Momentic Raises $15M Series A to Build the Definitive Verification Layer for Software

For years, automated testing has promised to eliminate manual QA. Every new framework claims you can “write once, run forever, catch every bug.” The reality is harsher: flaky tests, constant maintenance, and regressions that still slip into production.

Now AI coding tools like GitHub Copilot and Cursor let developers ship code dramatically faster. Which is incredible, until you realize you’re shipping bugs faster too. Traditional testing tools was already struggling. Now it just can’t keep up.

Today, we’re announcing that Momentic has raised a $15 million Series A led by Standard Capital, with participation from Dropbox Ventures and existing investors Y Combinator, FCVC, Transpose Platform, and Karman Ventures. This funding accelerates our mission to build the definitive verification layer for software

Verification for Modern, AI-Native Software Teams

Momentic is the definitive source of truth for how your product works. Teams describe tests in plain English, and our AI handles everything else: navigating user flows, interacting with screens, and validating results.

Instead of tying tests to fragile DOM selectors, Momentic tracks user intent. When your UI changes, tests adapt automatically. The result is a verification layer that keeps up with the pace of AI-accelerated development. No brittle tests, no endless test maintenance, just signals you can trust.

We started Momentic after seeing too many engineering teams drowning in broken tests while bugs still reached production. AI has made us dramatically faster at writing code, but the tools responsible for verifying that code were stuck in the past. This round gives us the resources to build the intelligent guardrail that modern software development now requires.

Reliability at Billion-Step Scale

Companies like Notion, Quora, Webflow, and Xero already use Momentic to ship with confidence. In the last month alone, Momentic executed more than 200 million steps and caught over 390,000 bugs, automating the equivalent of nearly 300,000 hours of manual testing.

Since 2024, customers have run more than 2 billion steps on Momentic. Reproducing that manually would take multiple decades. This is what it looks like when verification moves at the speed of AI.

For many teams, Momentic becomes a core part of the development workflow. At Notion, every engineer runs Momentic tests on every PR, merge, and deploy. The result is faster releases with higher confidence in every deploy.

What’s Next

Most of all, I’m grateful to everyone who’s helped get Momentic here: our team, investors, friends and family, and especially the customers who trusted us early. Everything we build is shaped by working alongside you.

If you’re excited about our mission, we’d love to meet you. We’re hiring across engineering, sales, and marketing. Check out open roles here.

We’re just getting started.
