What is not verified
No revenue figure was found. The company says customers pay and lists a price, but no independent source confirms that these customers pay. A payment-processor profile, a filing or an interview with revenue would settle it. The funding amounts rest on the company's press release and on SiliconANGLE. SiliconANGLE's two named rounds add up to US$18.7 million, and it does not explain the other US$0.5 million. Software Testing Magazine says only that Momentic "claims" 2,600 users. No earlier name or earlier company was found; no source dates the team of 18. This story is grade E: the business is real and its product, price and customers are described from public pages, but no revenue figure was checked. Aiolum shows it as an idea worth studying, not as proof that it makes money.
Momentic is an end-to-end test platform. An end-to-end test opens the real app and clicks through a task, such as signing up, to check the whole path. Momentic's agent follows a test written in English and finds a moved button again, which the company calls self-healing tests. The tests are saved as YAML files (a plain text format) in the customer's own code repository.
Wei-Wei Wu (CEO) and Jeff An (CTO) founded the company in late 2023, as SiliconANGLE reported after an interview with Wu. The company's own site says it is a Y Combinator W24 company. SiliconANGLE reported a US$3.7 million seed round on 4 March 2025, and the company announced a US$15 million Series A on 24 November 2025. In November 2026 Y Combinator lists a team size of 18.
No revenue figure was found in any downloaded source, so the evidence grade is E. What is checked is a published price list, a company that sells it, and press that names customers. The statement that these customers pay comes from the company itself.

Why did Momentic work?
Four causes, in the order they mattered. Each one is a reusable lesson.
The founders built a tool for testing work they disliked
The Y Combinator launch post is signed by Wei-Wei and Jeff. It says: "We started Momentic because we hated testing." It also says: "At Nashi, I spent four hours every Thursday evening manually testing before a release." The about page says the CEO was Nashi's first employee and founding engineer.
Plain-English tests replace scripts that break when the screen changes
SiliconANGLE quoted the CEO: because a test is described as intent, the script can evolve "as long as the intent stays the same". The about page says every test is a YAML file the customer keeps in version control.
Plans charge by test step and by minutes of runtime
The pricing page charges US$0.0125 for a test step. The same page charges US$0.025 for a step made by AI or by failure recovery. It lists a hosted browser at US$0.005 a minute. Every plan includes a monthly balance, and there is no charge per user.
How it was built
These details come from the company's own pages. They are grade C. [2, 5]
- Tests are YAML specs that live in the customer's code repository and run in continuous integration systems such as GitHub Actions, the about page says.
- The agent runs tests on hosted browsers, iOS simulators and Android emulators. The same spec format covers web and mobile.
- The privacy policy says Momentic uses artificial intelligence tools from Anthropic, OpenAI, xAI and Google in its services.
- The company ships command-line tools and MCP servers. An MCP server is a standard way for an AI coding agent to call outside tools. Agents such as Claude Code and Cursor can use it to write and run tests.
Tools named in the sources
Each one opens its page in the Tools tab, with every story that uses it.
Who tried this before Momentic, and why did they fail?
Three companies in a database of failed startups built developer tools: mobile app testing, AI code completion and maps of code. The values below are from that database, read on 11 November 2026, and are not independently verified.
Testmunk
The promiseAutomated testing of mobile apps on real devices, to save developer time.
Why it diedThe record says it could not stand out from BrowserStack and Sauce Labs. It also says a device farm cost too much to run.
Kite DevTool
The promiseAI code completion inside the editor, to make developers faster.
Why it diedThe record says GitHub Copilot, launched in June 2021, gave better suggestions with large language models. Kite's older models could not match them.
CodeSee
The promiseMaps of a codebase, to help developers understand complex code.
Why it diedThe record says teams saw the need only now and then, and kept to free alternatives. Companies that could pay asked for custom work.
The failed startups come from our database of 1,749 dead startups, retold here in our own words. Its entries are AI-assisted summaries of public sources, so these cards carry no evidence grade.
What changed
Testmunk and Kite fell to larger competitors, and CodeSee found that a tool used only now and then was hard to sell. Momentic is a tool that runs on every code change, which is a frequent use. It also writes tests in plain English with an AI agent.
The funding is the other difference. Momentic raised US$19.2 million in total, according to SiliconANGLE. Testmunk burned US$120K by the record's count. Hosted browsers and devices cost machine time, and Testmunk's record names its device farm as a cost problem.
Can one person copy Momentic now?
The idea, yes. The business, only with funding and sales.
A solo founder can copy the first step: describe tests in English and let a model run them. The rest needs money. Hosted browsers, emulators and simulators cost minutes of machine time, and SiliconANGLE reported US$19.2 million raised in total.
Where it is still open: Test agents for one framework, one industry or one platform, such as games, voice apps or browser extensions.
- 1Pick one kind of app, such as web apps, and write tests as sentences that a model turns into steps.
- 2Keep the tests as files in the customer's repository, so the customer owns them.
- 3Charge from a monthly dollar balance, so the price follows the machine time used.
- 4Show a price list from the start, as the company did in December 2023.
How much revenue does Momentic make?
Each row shows the evidence grade and the source numbers from the list at the end of this page. The grades are explained in How Aiolum verifies.
| Fact | Value | Grade | How we know | Sources |
|---|---|---|---|---|
| Paid plans, November 2026 | Scale at US$500 a month; Enterprise custom; Free at US$0 | C | Pricing page, read 11 November 2026: "Scale ... $500 / month", "$500 of usage each month". The terms of use say a customer pays the fees "charged on the Momentic website" or on an order form. | [3, 4] |
| Founded | late 2023 | C | SiliconANGLE, 4 March 2025: the two founders "founded Momentic in late 2023". The company's about page and Y Combinator also give 2023. The press release of 24 November 2025 says the company's founding was in late 2023. | [8, 2, 7, 9] |
| Earlier name or product | none found | C | The earliest Internet Archive copy of momentic.ai is dated 30 October 2023 and already uses the name Momentic, with a waitlist. The terms and privacy pages name Momentic, Inc.; no source names an earlier company. | [12, 4, 5] |
| Operating company | Momentic, Inc. | C | Privacy policy, updated 8 May 2026, and the terms of use. San Francisco is given as the headquarters on the about page. | [5, 4, 2] |
| Team at the start and now | 2 co-founders; Y Combinator lists a team size of 18 | C | The about page names two founders. The Y Combinator company page, read 11 November 2026, shows "Team Size: 18" with no date. Y Combinator's launch post is signed by the two founders. | [2, 7] |
| Seed round | US$3.7 million, 4 March 2025 | C | SiliconANGLE reported the round, with FundersClub, General Catalyst, Y Combinator and AI Grant named as participants. | [8] |
| Series A | US$15 million, 24 November 2025 | C | The company's press release says Standard Capital led it. Standard Capital's portfolio page lists the round as "Series A" and "$15M". SiliconANGLE put the total raised at US$19.2 million. | [9, 13, 10] |
| Customer counts the company gives | 2,600 users; 1,600+ teams; 100+ engineering teams | C | Software Testing Magazine, 25 November 2025, wrote that Momentic claims 2,600 users. The Y Combinator page says 1,600+ teams. The customers page says "Plus 100+ engineering teams". | [11, 7, 6] |
| Usage counters on the home page | 117,010 bugs caught; 80,290 pull requests verified | C | Counters on the home page, read 11 November 2026, with no date and no method. They are the company's own numbers. | [1] |
| Early plans, December 2023 | Team plan at US$300 a month; free plan joined by waitlist | C | Internet Archive copy of momentic.ai of 7 December 2023: Team "$300 /month", 1,000 runs a month, 10 seats; the free plan said "Join the waitlist". | [12] |
| Time from the first public page to November 2026 | 36 months | calc | Calculated: 30 October 2023 to 11 November 2026, in whole months. | [12, 3] |
How to read this table: a grade C value is what the company says on its own pages or in its own press release. It can also be what a trade outlet reported from the company. A "calc" value (grade X) was computed on this page. No value comes from a payment processor, a filing or a journalist's own check of documents.
| Plan | Per month, billed yearly (US$) | Per month, billed monthly (US$) | Limit |
|---|---|---|---|
| Free | 0 | 0 | US$50 of usage a month, 5 concurrent browsers, 30-day results |
| Scale | 500 | US$500 of usage a month, 25 concurrent browsers, shared Slack channel | |
| Enterprise | custom | custom | SAML single sign-on, audit log, SLA, account manager |
Plans are usage-based. Each plan includes a dollar balance that test steps, hosted runtime, AI features and Mo draw from, with no charge per user. The Free plan needs no credit card. Usage never bills past the balance; runs pause at zero. Scale can add funds from US$50. Enterprise pricing is custom and based on tests.
When did Momentic launch, and how did it grow?
From a waitlist page in October 2023 to a platform with paid plans and a US$15 million Series A, in about three years. The sources are the company's pages, press, Y Combinator and the Internet Archive.

What could go wrong for Momentic?
The risks are the mirror image of the causes above.
What is not verified
No revenue figure was found. The company says customers pay and lists a price, but no independent source confirms that these customers pay. A payment-processor profile, a filing or an interview with revenue would settle it. The funding amounts rest on the company's press release and on SiliconANGLE. SiliconANGLE's two named rounds add up to US$18.7 million, and it does not explain the other US$0.5 million. Software Testing Magazine says only that Momentic "claims" 2,600 users. No earlier name or earlier company was found; no source dates the team of 18.
Home page counters, logo wall and testimonials
The home page shows counters without dates, such as "Bugs caught 117,010", and a list of well-known customers. It prints first-name testimonials with a title and company, such as "Erdem" at Notion. The customer cards on the home page carry a first name, a surname initial and a role. The home page also shows "Bugs found vs. Codex on QA Bench 3.1x". QA Bench is the company's own benchmark. The company also says it is "SOC 2 Type 2 certified"; the report was not read. The press release of November 2025 says the platform prevented more than 390,000 bugs in one month, a figure larger than the home page total. The two pages do not say how each number is counted.
Customer counts differ between pages
Three sources give three different counts. Software Testing Magazine reported 2,600 users, and the Y Combinator page says 1,600+ teams. The customers page says "Plus 100+ engineering teams" after its 11 named customers. They are different units and dates. A reader should treat each as the company's own claim. The Y Combinator launch post offers US$250 of free credits on sign-up, while the pricing page shows US$50 a month.
From two founders to a funded company
The company started with two founders. Y Combinator now lists 18 people, and its press release says it is hiring in engineering, product and go-to-market roles. A reader copying only the idea does not need that team. The sources report funding but do not say what it paid for.
