Weave Communications, Inc.

Up to 981,405 Shares of Common Stock Offered by Selling Stockholders

We are registering the proposed resale or other disposition from time to time of up to 981,405 shares of our common stock (the “Resale Shares”) by the selling stockholders identified in this prospectus supplement. The Resale Shares were issued or may be issued to the selling stockholders in connection with the TrueLark Acquisition described below. We relied upon the exemption from registration provided by section 4(a)(2) and/or Regulation D of the Securities Act of 1933, as amended (the “Securities Act”), and the rules promulgated thereunder with respect to the initial issuance of Resale Shares.

To the extent that any selling stockholders resell any Resale Shares, the selling stockholders may be required to provide you with this prospectus identifying and containing specific information about the selling stockholders and the amount and terms of the securities being offered. You should read this prospectus before you invest. We will not receive any proceeds from the sale of our common stock by the selling stockholders.

On May 4, 2025, we entered into an Agreement and Plan of Merger, amended on May 16, 2025 (as amended, the “Merger Agreement”), by and among the Company, Project Sparrow Merger Sub, Inc., a Delaware corporation and a wholly-owned subsidiary of the Company (“Merger Sub”), Vidurama, Inc., a Delaware corporation doing business as TrueLark (“TrueLark”), Srivatsan Laxman, solely in his capacity as representative of the indemnifying stakeholders, pursuant to which we acquired TrueLark through a merger of Merger Sub with and into TrueLark (the “TrueLark Acquisition”). The closing of the TrueLark Acquisition occurred on May 16, 2025. In connection with the closing, 931,438 shares of our common stock were issued or are issuable to certain TrueLark stakeholders, and we paid cash in lieu of shares to unaccredited investors. In addition, a total of 49,967 shares of our common stock were held back by us from the merger consideration as security for potential post-closing adjustments and for indemnification and other obligations of the TrueLark stakeholders set forth in the Merger Agreement for a period of up to twelve months following the closing, which may result in the issuance of additional shares of our common stock to certain TrueLark stakeholders.

The selling stockholders may sell any or all of their Resale Shares from time to time on The New York Stock Exchange (the “NYSE”) or any other stock exchange, market, or trading facility on which shares of our common stock are traded or in private transactions. These sales may be at fixed prices, at prevailing market prices at the time of sale, at varying prices determined at the time of sale, or at negotiated prices. See “Plan of Distribution” in this prospectus supplement.

The selling stockholders may sell some, all or none of the Resale Shares offered by this prospectus supplement and we do not know when or in what amount the selling stockholders may sell their Resale Shares hereunder. We will not receive any of the proceeds from the sale of the Resale Shares by the selling stockholders. All expenses of registration incurred in connection with this offering are being borne by us. All selling and other expenses incurred by the selling stockholders will be borne by the selling stockholders.

We are registering the Resale Shares pursuant to a registration rights agreement, entered into in connection with the TrueLark Acquisition by and among us, TrueLark, and certain stakeholders of TrueLark.

Our common Stock is listed on the NYSE under the symbol “WEAV.” On June 4, 2025, the last reported sale price of our common stock on the NYSE was $9.68 per share. Our principal executive office is located at 1331 West Powell Way, Lehi, Utah 84043.

Description of the TrueLark Acquisition

On May 4, 2025, we entered into an Agreement and Plan of Merger, amended May 16, 2025 (as amended, the “Merger Agreement”), by and among the Company, Project Sparrow Merger Sub, Inc., a Delaware corporation and a wholly-owned subsidiary of the Company (“Merger Sub”), Vidurama, Inc., a Delaware corporation doing business as TrueLark (“TrueLark”), Srivatsan Laxman, solely in his capacity as representative of the indemnifying stakeholders, and the other parties thereto, pursuant to which we acquired TrueLark through a merger of Merger Sub with and into TrueLark (the “TrueLark Acquisition”). The closing of the TrueLark Acquisition occurred on May 16, 2025. In connection with the closing, 931,438 shares of our common stock were issued or are issuable to certain TrueLark stakeholders (the “Closing Shares”), and we paid cash in lieu of shares to unaccredited investors. In addition, a total of 49,967 shares of our common stock were held back by us (the “Holdback Shares” and together

S-1

with the Closing Shares, the “Resale Shares”) from the merger consideration as security for potential post-closing adjustments and for indemnification and other obligations of the TrueLark stakeholders set forth in the Merger Agreement for a period of up to twelve months following the closing, which may result in the issuance of additional shares of our common stock to certain TrueLark stakeholders.

The Offering

Our common stock is currently listed on the NYSE under the symbol “WEAV.” We will not receive any of the proceeds from the sale of the Resale Shares by the selling stockholders.

We relied upon the exemption from registration provided by section 4(a)(2) and/or Regulation D of the Securities Act of 1933, as amended (the “Securities Act”), and the rules promulgated thereunder with respect to the issuance of Resale Shares. See “Selling Stockholders” beginning on page S-7 of this prospectus supplement. We will not receive any of the proceeds from the sale of the Resale Shares.

RISK FACTORS

Investing in our securities involves a high degree of risk. You should carefully consider the risks referenced below and described in the documents incorporated by reference in this prospectus supplement, as well as other information we include or incorporate by reference into this prospectus supplement before making an investment decision. Our business, financial condition or results of operations could be materially adversely affected by the materialization of any of these risks. The trading price of our securities could decline due to the materialization of any of these risks, and you may lose all or part of your investment. This prospectus supplement and the documents incorporated herein by reference also contain forward-looking statements that involve risks and uncertainties. Actual results could differ materially from those anticipated in these forward-looking statements as a result of certain factors, including the risks referenced below and described in the documents incorporated herein by reference, including (i) our most recent annual report on Form 10-K which is on file with the SEC and incorporated herein by reference, (ii) our quarterly reports on Form 10-Q filed subsequent to such Form 10-K, each of which is on file with the SEC and incorporated herein by reference, and (iii) other documents we subsequently file with the SEC that are deemed incorporated by reference into this prospectus supplement.

Risks Related to the TrueLark Acquisition

We may not realize all of the anticipated outcomes and benefits of the TrueLark Acquisition.

The benefits we expect to achieve as a result of the TrueLark Acquisition will depend, in part, on our ability to realize anticipated growth opportunities and cost synergies. Our success in realizing these growth opportunities and cost synergies, and the timing of this realization, depends on the successful integration of TrueLark’s business and operations with our business and operations. Even if we are able to integrate our business with TrueLark’s business successfully, this integration may not result in the realization of the outcomes and benefits, growth opportunities and cost synergies we currently expect within the anticipated time frame or at all. Moreover, we anticipate that we will incur substantial expenses in connection with the integration of TrueLark’s business with our business. While we anticipate that certain expenses will be incurred, such expenses are difficult to estimate accurately, and may exceed current estimates.

Accordingly, the outcomes and benefits from the TrueLark Acquisition may be offset by costs incurred or delays in integrating the companies, which could cause the outcomes and benefits we anticipate to be inaccurate or not realized.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus supplement and the accompanying prospectus, including the documents incorporated by reference herein and therein, contain forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. All statements contained in or incorporated by reference in this prospectus supplement and the accompanying prospectus other than statements of historical fact, including statements regarding our future results of operations and financial position, our business strategy and plans, and our objectives for future operations, are forward-looking statements. The words “believe,” “may,” “will,” “estimate,” “continue,” “anticipate,” “would,” “could,” “should,” “intend,” “plan,” “expect” and similar expressions are intended to identify forward-looking statements. We have based these forward-looking statements largely on our current expectations and projections about future events and trends that we believe may affect our financial condition, results of operations, business strategy, short-term and long-term business operations and objectives, and financial needs. These forward-looking statements are subject to a number of risks, uncertainties and assumptions, including but not limited to the risks described in this prospectus supplement, the accompanying prospectus and any documents incorporated by reference herein or therein, including those described in the “Risk Factors” included and incorporated by reference herein. Moreover, we operate in a highly competitive and rapidly changing environment. New risks emerge from time to time. It is not possible for our management to predict all risks, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements we may make. In light of these risks, uncertainties and assumptions, the future events and trends discussed in this prospectus supplement and the accompanying prospectus may not occur and actual results could differ materially and adversely from those anticipated or implied in the forward-looking statements.

You should not rely upon forward-looking statements as predictions of future events. The events and circumstances reflected in the forward-looking statements may not be achieved or occur. Although we believe that the expectations reflected in the forward-looking statements are reasonable, we cannot guarantee future results, levels of activity, performance or achievements. Please take into account that forward-looking statements speak only as of the date of this prospectus supplement or the documents incorporated by reference, the date of any such document. Although we undertake no obligation to revise or update any forward-looking statements, whether as a result of new information, future events or otherwise, you are advised to review any additional disclosures we make in the documents we subsequently file with the SEC that are incorporated by reference in this prospectus supplement and the accompanying prospectus.

DESCRIPTION OF THE TRUELARK ACQUISITION

In addition, a total of 49,967 shares of our common stock were held back by us from the merger consideration as security for potential post-closing adjustments and for indemnification and other obligations of the TrueLark stakeholders set forth in the Merger Agreement for a period of up to twelve months following the closing (the “Holdback Shares”). Release of the Holdback Shares may result in the issuance of additional shares of our common stock to certain TrueLark stakeholders.

In connection with the closing of the TrueLark Acquisition, Weave entered into a registration rights agreement (the “Registration Agreement”) with TrueLark and certain stakeholders of TrueLark pursuant to which Weave agreed to register the Resale Shares under the Securities Act.

Weave is required under the terms of the Registration Agreement to prepare and file a registration statement or a prospectus supplement to an effective automatic shelf registration statement, covering the Resale Shares with the SEC as soon as practicable after the closing of the TrueLark Acquisition and to use commercially reasonable efforts keep the registration statement continuously effective until the earlier of the date that all Shares have been sold thereunder or are able to be publicly sold by relying on Rule 144 of the Securities Act without registration. We have filed this prospectus supplement to fulfill certain obligations under the Registration Agreement.

A copy of the Registration Agreement will be filed as an exhibit to a Current Report on Form 8-K filed under the Exchange Act, and incorporated by reference in this prospectus supplement.

PLAN OF DISTRIBUTION

We are registering the Resale Shares issued to the selling stockholders to permit the resale of these shares of common stock by the holders from time to time after the date of this prospectus supplement.

No broker, dealer or underwriter has been engaged in connection with soliciting such exchange, exercise, or resale, and no commission or other compensation will be paid to any person in connection with solicitation of such exchange, exercise, or resale. No broker, dealer or underwriter has been engaged in connection with this offering.

The selling stockholders, which as used herein includes donees, pledgees, assignees, transferees and other successors-in-interest selling shares of common stock or interests in shares of common stock received after the date of this prospectus from a selling stockholder as a gift, pledge, partnership distribution or other transfer, may, from time to time, sell, transfer or otherwise dispose of any or all of their shares of common stock or interests in shares of common stock on any stock exchange, market or trading facility on which the shares are traded or in private transactions. These dispositions may be at fixed prices, at prevailing market prices at the time of sale, at prices related to the prevailing market price, at varying prices determined at the time of sale, or at negotiated prices.

Sales of shares of our common stock by the selling stockholders named in this prospectus may be made from time to time in one or more transactions in the over-the-counter market, on any exchange or quotation system on which shares of our common stock may be listed or quoted, in negotiated transactions or in a combination of any such methods of sale, at fixed prices that may be changed, at market prices prevailing at the time of sale, at prices related to such prevailing market prices or at negotiated prices. The shares may be offered directly, to or through agents designated from time to time or to or through brokers or dealers, or through any combination of these methods of sale. The methods by which the shares may be sold include:

•block trades (which may involve crosses) in which the broker or dealer will attempt to sell the shares as agent but may position and resell a portion of the block as principal to facilitate the transaction;

•purchases by a broker or dealer as principal and resales by the broker or dealer for its own account pursuant to this prospectus;

•exchange distributions or secondary distributions in accordance with the rules of the applicable exchange;

•ordinary brokerage transactions and transactions in which the broker or dealer solicits purchasers;

•privately negotiated transactions;

•the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise;

•the settlement of short sales;

•a combination of any of the foregoing methods of sale; and

•any other method permitted by applicable law.

An agent, broker or dealer may receive compensation in the form of discounts, concessions or commissions from the selling stockholders or the purchasers of the shares for whom such brokers or dealers may act as agents or to whom they sell as principals, or both (which compensation as to a particular broker or dealer might be in excess of customary commissions). A member firm of an exchange on which our common stock is traded may be engaged to act as the selling stockholders’ agent in the sale of shares by the selling stockholders.

In connection with distributions of the Resale Shares offered by this prospectus or otherwise, the selling stockholders may enter into hedging transactions with brokers or dealers or other financial institutions with respect to our common stock. In connection with these transactions, the brokers or dealers or other financial institutions may engage in short sales of our common stock in the course of hedging the positions they assume with the selling stockholders. The selling stockholders may also sell our common stock short to effect its hedging transactions and deliver shares of common stock covered by this prospectus to close out short positions and to return borrowed shares

S-9

in connection with such short sales. The selling stockholders may also loan or pledge shares of common stock to broker-dealers that in turn may sell such shares.

In addition, any shares of our common stock covered by this prospectus that qualify for sale pursuant to Rule 144 of the Securities Act may be sold under Rule 144 rather than pursuant to this prospectus.

The aggregate proceeds to the selling stockholders from the sale of the Resale Shares offered by it pursuant to this prospectus will be the purchase price of the shares less discounts or commissions, if any. The selling stockholders reserve the right to accept and, together with its agents from time to time, to reject, in whole or in part, any proposed purchase of shares of common stock to be made directly or through agents.

Each broker-dealer that receives Resale Shares for its own account pursuant to this prospectus must acknowledge that it will deliver the prospectus in connection with any sale of the Resale Shares. If required, this prospectus may be amended or supplemented on a continual basis to describe a specific plan of distribution. We will make copies of this prospectus available to the selling stockholders, brokers and dealers for purposes of satisfying the prospectus delivery requirements of the Securities Act, if applicable.

In order to comply with the securities laws of some states, if applicable, the Resale Shares offered by this prospectus may be sold in these jurisdictions only through registered or licensed brokers or dealers. In addition, in some states the Resale Shares may not be sold unless they have been registered or qualified for sale or an exemption from registration or qualification requirements is available and is complied with as part of such sale.

The selling stockholders and any other person participating in such distribution will be subject to certain provisions of the Exchange Act. The Exchange Act rules include Regulation M, which may limit the timing of purchases and sales of any of our common stock by the selling stockholders and any other such person.

ABOUT THIS PROSPECTUS

RISK FACTORS

Investing in our securities involves a high degree of risk. Before making a decision to invest in our securities, you should carefully consider the risks described under the heading “Risk Factors” in the applicable prospectus supplement and any related free writing prospectus, and discussed under “Part I, Item 1A. Risk Factors” contained in our most recent annual report on Form 10-K and in “Part II, Item 1A. Risk Factors” in our most recent quarterly report on Form 10-Q filed subsequent to such Form 10-K, as well as any amendments thereto, which are incorporated by reference into this prospectus and the applicable prospectus supplement in their entirety, together with other information in this prospectus and the applicable prospectus supplement, the documents incorporated by reference herein and therein, and any free writing prospectus that we may authorize for use in connection with a specific offering. See “Where You Can Find Additional Information.”

We could be materially and adversely affected by any or all of these risks or by additional risks and uncertainties not presently known to us or that we currently deem immaterial that may adversely affect us or a particular offering in the future.

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

This prospectus and any prospectus supplement, including the documents incorporated by reference herein and therein, contain forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. All statements contained in or incorporated by reference in this prospectus and any prospectus supplement other than statements of historical fact, including statements regarding our future results of operations and financial position, our business strategy and plans, and our objectives for future operations, are forward-looking statements. The words “believe,” “may,” “will,” “estimate,” “continue,” “anticipate,” “would,” “could,” “should,” “intend,” “plan,” “expect” and similar expressions are intended to identify forward-looking statements. We have based these forward-looking statements largely on our current expectations and projections about future events and trends that we believe may affect our financial condition, results of operations, business strategy, short-term and long-term business operations and objectives, and financial needs. These forward-looking statements are subject to a number of risks, uncertainties and assumptions, including but not limited to the risks described in this prospectus, any accompanying prospectus supplement and any documents incorporated by reference herein or therein, including those described in the “Risk Factors” section incorporated by reference herein. Moreover, we operate in a highly competitive and rapidly changing environment. New risks emerge from time to time. It is not possible for our management to predict all risks, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements we may make. In light of these risks, uncertainties and assumptions, the future events and trends discussed in this prospectus and any prospectus supplement may not occur and actual results could differ materially and adversely from those anticipated or implied in the forward-looking statements.

You should not rely upon forward-looking statements as predictions of future events. The events and circumstances reflected in the forward-looking statements may not be achieved or occur. Although we believe that the expectations reflected in the forward-looking statements are reasonable, we cannot guarantee future results, levels of activity, performance or achievements. Please take into account that forward-looking statements speak only as of the date of this prospectus or, in the case of any accompanying prospectus supplement or documents incorporated by reference, the date of any such document. Although we undertake no obligation to revise or update any forward-looking statements, whether as a result of new information, future events or otherwise, you are advised to review any additional disclosures we make in the documents we subsequently file with the SEC that are incorporated by reference in this prospectus and any prospectus supplement. See “Where You Can Find Additional Information.”
