Israeli founders Maayan Salom and Or Avidov sold Elementary Data, a Y Combinator W22 startup, to Boomi for a reported $40-45M. Who they are and what's next.
Elementary Data (אלמנטרי דאטה), an Israeli data observability startup in Tel Aviv, was founded by Maayan Salom and Or Avidov and has been acquired by Boomi, a US integration software company, in a deal announced October 19, 2026. CTech by Calcalist reported a price of $40 to $45 million in cash and stock. Elementary, a Y Combinator Winter 2022 company, had raised $8.5 million, and all 17 employees are joining Boomi.

What did Boomi buy when it acquired Elementary Data?
Boomi bought a data observability and reliability layer. Elementary builds software that watches the freshness, volume and quality of the data that feeds dashboards, analytics models and, increasingly, AI agents, so that data teams find problems before business users do. The platform also tracks column-level data lineage and exposes data health information to AI tools through a Model Context Protocol server.
Elementary began as an open-source project for data engineers. Its open-source tool draws more than 1.1 million downloads a month, according to Dealroom, and the company says more than 1,500 data teams use its products. Customers named in coverage include Fiverr and Patagonia. A commercial product, Elementary Cloud, was added on top of the open-source core.
For Boomi, which connects data and applications for more than 30,000 customers, the pitch is simple. Moving data is one problem, and trusting it is another. Boomi chairman and CEO Steve Lucas framed the purchase around the idea that AI is only as trustworthy as the data behind it.
Who are Maayan Salom and Or Avidov?
Maayan Salom is the CEO and Or Avidov is the chief product and technology officer. CTech reports that both are veterans of the IDF intelligence unit 8200 (יחידה 8200). Before Elementary, Salom managed incident response engagements at Sygnia, and Avidov was director of engineering at Singular.
Y Combinator's company page lists Elementary as founded in 2021 and based in Tel Aviv. The Jerusalem Post puts the founding in August 2021. Some US coverage says 2022, so the safest description is a startup founded in 2021 that went through Y Combinator in the Winter 2022 batch.
| Founder | Role at Elementary | Background reported |
|---|---|---|
| Maayan Salom | CEO and co-founder | Unit 8200 veteran; incident response engagement manager at Sygnia; years in data analysis |
| Or Avidov | Chief product and technology officer, co-founder | Unit 8200 veteran; director of engineering at Singular |
The pairing is a familiar one in Israeli tech: one founder from security and analysis, one from engineering. The two built a product around a problem they described as constant for data teams, which is learning that a number is wrong only after someone senior asks about it.
How much did Boomi pay, and is it a good exit?
Boomi did not disclose the price. CTech by Calcalist reported $40 to $45 million in cash and stock, and several outlets later cited roughly $43 million. According to Dealroom and other coverage, Elementary had raised $8.5 million from TLV Partners, Cowboy Ventures, Y Combinator and angel investors, so the reported price is about five times the capital raised.
| Item | Detail |
|---|---|
| Acquirer | Boomi (Conshohocken, Pennsylvania) |
| Target | Elementary Data (Tel Aviv) |
| Announced | October 19, 2026 |
| Reported price | About $40 to $45 million, cash and stock (not confirmed by Boomi) |
| Capital raised by Elementary | $8.5 million (TLV Partners, Cowboy Ventures, Y Combinator, angels) |
| Employees | 17, all in Israel, joining Boomi |
| Y Combinator batch | Winter 2022 (W22) |
Is that a good result? For a 17-person company with a modest funding history, a mid-eight-figure price is a clean אקזיט (exit), though one analyst note described it as a targeted technology-and-team purchase rather than a trophy deal. Both readings can be true. The real test, as Dealroom put it, is whether Boomi folds its three Israeli acquisitions into one coherent platform.
Why did Boomi buy a third Israeli company?
Because the three deals fit together. Rivery moves data, Lunar.dev manages how AI agents connect to APIs, and Elementary checks that the data is reliable. CTech noted that the three acquisitions line up around the movement, access and quality of enterprise data.
| Israeli company | What it does | Deal notes |
|---|---|---|
| Rivery | Data integration | Acquired in 2024; reported at about $100 million |
| Lunar.dev | Connectivity between AI agents and APIs | Acquired in 2026; terms undisclosed |
| Elementary Data | Data observability and reliability | Announced October 19, 2026; reported $40 to $45 million |
Boomi has said it intends to grow its Israeli presence considerably. For Israeli data and infrastructure founders, a buyer that has now done three local deals is a signal worth noting.
How did Y Combinator shape Elementary's path?
Y Combinator gave Elementary early validation and a US investor network. The company's disclosed funding, $8.5 million by the end of 2022 according to Dealroom, came from a mix of an Israeli fund (TLV Partners), a Silicon Valley seed fund (Cowboy Ventures), Y Combinator itself and angels. That pattern, an Israeli engineering team with US go-to-market backing, is typical of how Israeli developer-tool startups grow.
It also helped that Elementary started open source. A free tool that data engineers can install in minutes builds a community first and revenue second. Boomi's announcement cited a community of roughly 4,000 members, which is the kind of distribution a larger platform company pays for.
What is the Y Combinator route for Israeli startups?
Y Combinator (YC) is the US accelerator behind companies such as Airbnb, Dropbox and Reddit. It invests in batches and runs a roughly three-month program that ends with a demo day. Israeli סטארטאפים (startups) have used it for years, from Guesty and Cleanly in the mid-2010s to newer developer-tool and AI companies.
How does YC work for an Israeli company?
According to a 2026 guide for Israeli founders from Velo Labs, YC's standard deal is $500,000: $125,000 for 7 percent plus $375,000 on an uncapped MFN SAFE. The same guide notes that YC invests only in US, Canadian, Cayman or Singapore corporations, so an Israeli company usually needs a parent company abroad, often through a Delaware flip. That is why many Israeli-founded YC companies are headquartered in the US on paper while the engineering team stays in Israel.
How many Israeli startups have been through YC?
There is no single official count. One public directory, built from YC's company listings, lists 28 YC companies based in Israel out of 6,207 across every batch since 2005. That figure counts only companies tagged with an Israeli location, so it understates the number of Israeli-founded teams, many of which list a US address. Treat it as a floor, not a total.
| Israel-based YC company | Listed in the directory |
|---|---|
| Elementary | Yes (W22; acquired by Boomi) |
| D-ID | Yes |
| Datree | Yes |
| Traceloop | Yes |
| Darrow | Yes |
| Cymmetria | Yes |
| Guggy | Yes |
| Sherloq | Yes |
Why do Israeli founders choose YC?
Three reasons come up repeatedly. The first is access to US customers and investors that a Tel Aviv base does not provide by default. The second is the signal a YC badge sends to later-stage funds. The third is the alumni network, which helps with early enterprise introductions. Elementary used all three, and the Boomi deal shows the model can end in a strategic sale, not only a venture-scale exit.
What does the deal say about Israeli startup exits in 2026?
It sits inside a busy exit month. Geektime counted 10 acquisition and merger deals by Israeli startups in October 2026, including Intel's purchase of the quantum computing company Classiq for about $2.3 billion and the sale of the eight-month-old startup Inferize for $150 million. Elementary's roughly $43 million is at the smaller end, but it shows that mid-sized outcomes are still available to well-run, low-burn teams.
The pattern across these deals is that US buyers are shopping in Israel for AI infrastructure, data quality and security. Freshworks, for example, bought two Israeli companies, Torii and Robusta, within two weeks, according to the same Geektime roundup. For Israeli founders in data and AI tooling, the buyer universe is wide.
What happens to Elementary's product and team now?
Both the commercial product and the open-source project continue under Boomi. Coverage of the announcement says existing customers should see uninterrupted service and that there are no immediate changes to the open-source code repository or its release process. All 17 Elementary employees, who are based in Israel, are moving over to Boomi.
The open questions are the usual ones after a tuck-in deal. Will the open-source community stay engaged under a larger owner, and how quickly will the Elementary technology appear inside the Boomi Enterprise Platform? Boomi says it will extend monitoring across data in warehouses and data moving between systems. Olam will follow how the integration develops.
