@wuweiweiwu The truth is out

[Henry Haefliger @HenryHaefliger]

Is it just me or were none of these labelled 'preview' until everyone realized the @DevinAI got way worse after they switched from Opus 4.7 to Opus 4.8?

POV: your PM just discovered Claude Code

[Henry Haefliger @HenryHaefliger]

@wuweiweiwu You could point cursor at it -> watch it break again in prod and not know why

[Henry Haefliger @HenryHaefliger]

@RhysSullivan @aidenybai @wuweiweiwu we got u

@daltonc Whether you're early stage or late enterprise. Save yourself the pain later.

@Robbie @wuweiweiwu @Campusgrad Let us know how you go @Robbie !!

@wuweiweiwu Before @MomenticAI

[Henry Haefliger @HenryHaefliger]

This is the only way I've been adding new tests for the past few months, and our coverage is higher than ever

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.

@OpenAI @linear @cognition @github is late to the party but you know they're always down to clown

[Henry Haefliger @HenryHaefliger]

3/4 of these companies are having incidents or major app breakages right now. Says a lot about building with AI but zero testing.

@OpenAI @linear @cognition do any of you want to try Momentic?

[Henry Haefliger @HenryHaefliger]

@OpenAI @linear @cognition @DevinAI We finally got a status update...

[Henry Haefliger @HenryHaefliger]

@OpenAI @linear @cognition @DevinAI Correction: now they're just stuck in "setting up..." indefinitely

[Henry Haefliger @HenryHaefliger]

Clicking any PR notification in the @linear app right now causes it to immediately crash

@MomenticAI V3 launch behind the scenes (Brynlee is working on docs for me)
