building the future of software testing @momenticai. formerly eng @retool, @robinhood, @google.

Proud to share we've raised a Series A led by Standard Capital!

We started out with a simple idea: make end-to-end tests not suck.

But as AI coding tools exploded in popularity, that kernel quickly evolved into a broader mission: to build the source of truth for how software should work.

We've already executed over 2 billion AI-powered steps on our platform.

We've prevented an estimated 400K bugs from reaching production.

Companies like @NotionHQ, @Xero, and @Quora trust us to validate every deployment before releasing.

And we're just getting started.

I'm beyond stoked to begin this next phase of our journey, as we grow the team and transform how software is built around the world! 🚀

Vanta invited me to a SOC 2 readiness call for a completely different company...and we dont even use Vanta

@MerrillLutsky @graphite legend! 🫡

[Jeff An @itsjeffan]

it's crazy how the same model deployed on different inference providers yields vastly different results.

im beginning to understand why researchers grow attached to a single cluster

@raunakdoesdev @Cloudflare your first mistake was paying for gcp support

[Jeff An @itsjeffan]

@wuweiweiwu @WorkOS you would think someone would get paged for this like instantly

[Jeff An @itsjeffan]

the incredible irony of using AI to estimate job loss caused by AI

[Jeff An @itsjeffan]

@chaitanyad0208 @steipete give @MomenticAI a try - we went a different approach and solved caching for mobile interactions

@skeptrune looks like Devin to me

new swag for the ergodox

[Jeff An @itsjeffan]

@Vercantez get better!

[Jeff An @itsjeffan]

@ansonlin entirely agree. unless you think there will be no novel user interfaces built in the future figma is not going anywhere

@HenryHaefliger this is why every morning i merge 5 auto-generated PRs before coffee

[Jeff An @itsjeffan]

Super excited to unveil what we've been focused on over the past few months!

This is not just an ordinary feature update, it's a paradigm shift for how testing should work.

It's been absolutely transformative seeing the reactions from beta users for our v3 testing agent, so much so that we thought a rebrand was in order.

[wei-wei @wuweiweiwu]

AI writes all your code. Does it still work?

That's the gap: coding agents are scaling output, but the same with bugs and incidents. The biggest bottleneck is QA: how can you make sure the code your agents just wrote doesn’t break everything?

The best QA are the ones who know everything about your product. Today, we give that knowledge to Momentic’s most capable agent.

Every Linear ticket, every PRD in Notion, every PR - Momentic knows all.

In just the past few weeks, our agents analyzed 70k+ test failures and created 600 tests. Achieving a 73% PR merge rate, and it’s growing fast.

We’re grateful for the trust of our customers, including Notion, Xero, Webflow, Retool, Runway, Bilt, and more.

@ben_finegold where are you playing?

[Jeff An @itsjeffan]

@wuweiweiwu or u might say "deadly turn"

[wei-wei @wuweiweiwu]

Our agent now triages every test failure for you > alerts your team if it's a real bug > fixes the test and opens a PR automatically when the user flow changes.

Beta testers already cut triage time by 30% 🔥

[Jeff An @itsjeffan]

@raunakdoesdev @useblacksmith yes we had to cache everything, turns out a lot of cdns block blacksmith. like our doppler installs would hang periodically

[Jeff An @itsjeffan]

thanks for the fun challenge and gear @Logitech!

a good bit of friendly competition to spice up @Microsoft Build

[Jeff An @itsjeffan]

learned 2 things today:
- there is a programming language called bicep
- people still write documentation in books

not sure which is more surprising

[Jeff An @itsjeffan]

@lizwessel unfortunately I think this is a feature and not a bug. IT team is never gonna replace themselves.
