Weave, organized in 2008 as Recall Solutions: what the SEC filings say about the dental front desk

What it says#

Weave Communications, Inc. filed a Form S-1 registration statement with the SEC on October 18, 2021. Under the heading "Corporate Information" it gives the company's origin in two sentences: "We were organized in Delaware in September 2008 as Recall Solutions, LLC. We converted into a Delaware corporation in October 2015 under the name Weave Communications, Inc." That same September 2008 sentence appears verbatim in the annual reports since, including the Form 10-K for fiscal 2025 filed on March 5, 2026.

The S-1 also dates the company a second way. In management's discussion, the same filing opens a paragraph with "Since our founding in 2011, we have evolved our platform, innovating and improving the products and integrations we provide for small businesses." The two dates sit about seventy pages apart in one document. The legal formation date is September 2008; the operating story the company tells investors starts in 2011. The filings do not say what Recall Solutions, LLC actually sold, so the original product is a name and nothing more on this record.

What the company became is described in detail. The S-1 calls Weave "a leading all-in-one customer communications and engagement software platform for small and medium-sized businesses" and describes the product as spanning "all forms of communications and customer engagement ranging from answering phones, to scheduling appointments, to sending text reminders, to requesting client reviews, to collecting payments, to sending email marketing campaigns." The architecture matters more than the feature list: "We create a comprehensive communications hub by deeply integrating with SMB's system of record, whether a practice management system, CRM or ERP software." In a dental office, the system of record is the practice management software, and Weave sits on top of it.

The dental origin is stated plainly. The S-1 estimates that dental "accounts for a majority of the establishments within our customer base" and puts the company's dental market penetration at "approximately 10% as of June 30, 2021," with combined penetration across all its verticals at roughly 3 percent. Those are the company's own estimates of its own market, not third party counts. The 2025 10-K keeps the same lineage: "We started in dental and have since successfully expanded to optometry, and veterinary."

The dependency runs the other way too, and the S-1 says so in its risk factors: "dental PMS product Dentrix provides critical functionality to our platform for a significant portion of our customer base, pursuant to a contract that provides for integration through July 2026, subject to certain conditions including third party access approval and security protocols for data protection and system integrity." A note to the financial statements adds the structural fact behind that risk: "Less than five providers make up the majority of practice management systems maintained by dentists and optometrists in the United States."

The numbers, as reported. At June 30, 2021 Weave had 21,227 locations under subscription across approximately 20,000 customers in the United States and Canada, and said its platform was used by over 130,000 monthly active users. Revenue was $45.7 million in 2019 and $79.9 million in 2020; net loss was $32.1 million and $40.4 million in those years. Dollar-based net retention was 102 percent at the end of 2020. The company completed its IPO on November 15, 2021, selling 5,000,000 shares at $24.00 a share for net proceeds of $111.6 million, after its stock began trading on the New York Stock Exchange as WEAV on November 11. By December 31, 2025 it reported 39,625 locations, revenue of $239.0 million, a net loss of $28.1 million, net revenue retention of 93 percent and gross retention of 89 percent. The 2025 10-K describes newer products including an AI receptionist that follows up on missed calls, and Weave Enterprise for multi-location groups and DSOs.

Who it applies to#

Any practice that has bought a phone and messaging layer, from Weave or anyone else. The filings are useful to an owner because they state, in a document with legal consequences for inaccuracy, what the category actually is: a communications hub bolted to the practice management system, sold per location, priced as a subscription, with hardware on a three-year depreciation schedule and onboarding costs recovered over a customer's life.

Front desk teams are the users named. The S-1 says the platform is used by "monthly active users," which it defines as users at customers who log on at least once in a month, and its description of the work, confirming appointments, answering missed calls, collecting payments by text, is front office work rather than clinical work.

It does not apply to the clinical side at all. Nothing here is cleared, approved or evaluated by any regulator for diagnosis or treatment. The company is regulated as an interconnected VoIP provider, which is why the filings spend pages on FCC 911 obligations and state VoIP registration, and those are the obligations that travel with a cloud phone system in your office.

What changed#

Before this category existed, the practice management system was the whole software stack and the phone was a separate utility. What these filings document is the arrival of a second vendor with its own subscription, sitting between the practice and the patient, holding the office's phone number and its text history. The S-1's 2019 and 2020 revenue figures and its location counts show the category scaling through the period when practices were closed or limited by COVID-19; the company told investors the pandemic "did not have a negative material impact on our revenue."

What changed since is consolidation of more functions into that layer: payments in April 2020, analytics in May 2020, forms in May 2021, then insurance eligibility checks that the 2025 10-K says use robotic process automation to "access dental payer portals directly," an AI receptionist, and an enterprise product for groups. The layer that started as reminders now touches money, insurance and the first conversation a new patient has with the office.

Where the source is#

The primary source is Weave Communications, Inc.'s Form S-1 registration statement on EDGAR, filed October 18, 2021, which contains the corporate history, the product description, the customer counts and the risk factors quoted here. The Form 10-K for fiscal 2025, filed March 5, 2026, supplies the current product description and the 2023 through 2025 revenue, loss, location and retention figures, and repeats the September 2008 sentence. The Form 10-K for fiscal 2021 carries the IPO details in Item 5 and in the notes, and the final prospectus is the Form 424(b)(4) of November 12, 2021. All are free and public on sec.gov; the SEC asks that automated requests identify themselves, which is how these were fetched. Where a sentence in this entry describes what the platform does, it is the company's own characterization in a filing, not an independent test of the software.
