Jeff An

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! 🚀

@mattaitken @bunjavascript @nodejs what's the implication? greater memory usage and possibly hanging application code?

Switching from Node to @bunjavascript gave us a 5x speed boost (28x better max latency) but there was a gotcha… Pending response promises don't resolve on client disconnect. @nodejs handles this automatically. Fix: resolve disconnects with 499. trigger.dev/blog/firebun

i swear there used to be a billboard here... something about delving into AI?

@jonathanzliu cursor crashes on me multiple times a day

i still use cursor. it's hella fast bro everything i tell it to do completes in <30secs i don't know why anybody would ever use anything else.

@adelwu_ @wuweiweiwu @daltonc just natural god given jaw line

@wuweiweiwu @itsjeffan @daltonc are you mewing @itsjeffan

Really enjoyed this convo that @itsjeffan and I had with @daltonc Here we discuss the founding of Momentic (back during buildspace it was called Screenwriter), the future of engineering, and our vision for the company Just realizing I'm permanently hunched 😆

@emkara exposed 😂

@daltonc @wuweiweiwu @MomenticAI @itsjeffan Rare moment to watch @itsjeffan out of the Patagonia and Arcteryx so it’s a must watch

Standard Capital just led the $15M Series A in Momentic. In the video linked below, I sit down with the founders of @MomenticAI, @wuweiweiwu and @itsjeffan. We discuss the company history, customers like Notion and Webflow, and what the future of vibecoding looks like.

Watch me fluster during my first ever podcast as we chat about our founding story, traction, and vision with one of the greatest minds in VC!

@daltonc @MomenticAI @wuweiweiwu Appreciate the fun conversation Dalton!

@wuweiweiwu Excited to see AI transform browser, mobile, and desktop testing!

Today, teams ship AI-generated code faster than they can verify it. AI will write most of the world's code, Momentic will make sure it works. We've raised a $15M Series A led by Standard Capital to build the definitive source of truth for software.

@topnames_MT down for us as well, no updates on the status page. can't even login to workos.com!

I'm migrating to WorkOS, and halfway through, WorkOS is down 🥶. Should I continue??? dashboard.workos.com

@cursor_ai @windsurf @warpdotdev ...seems like not a single provider properly sends notification/cancelled events!

has anyone successfully implemented tool cancellation in an mcp server? our abort signals don't seem to be firing when used through @cursor_ai , @windsurf or @warpdotdev

@forwarddeploy @saradu gets it done 🙏

Who are the best angels? The ones multiple founders would call their favorite for actually helping. I’m building a vetted list of Forward Deployed Angels. 👇 Tag the angels who have made the difference, i'd love to meet them and give em a hat

I TOLD U LAST DAY OF LAUNCH WEEK WOULD BLOW YOUR MIND Mobile testing is slow, flaky, and expensive. Timeouts every where. WebView context switching sucks. Emulators are slow af. Today we’re launching Momentic Mobile to change all that.

the lacroix tower is growing fast & we’re hiring a ton across gtm & eng - AE (2x) - SDR - Growth Marketer - Eng (♾️) come drink sparkling water with us jobs.ashbyhq.com/momentic

@raunakdoesdev doppler or bust

vercel env variables are such crazy bad dx it's insane no API, no bulk operations, crazy rate limits, and a max total environment variable size per project across all environments how does that make any sense

Kicking off launch week day 1: Momentic Copilot & MCP server Vibe coding meet vibe testing. The the quickest way to build and scale your end-to-end tests.

Confession time. Our AI-powered testing tool doesn't actually use AI. It's just my co-founder Jeff An running all our customers' tests from the office. While our competitors have spent millions training models for the last 12 months, we just ordered a $47 pair of binoculars from Amazon to help Jeff spot bugs more easily. Our customers have no idea and honestly, Jeff's still catching more bugs than most QA teams. Don't tell our investors though.

maybe now Gemini will stop making invalid tool calls in windsurf?

@AlvinRyanputra @raunakdoesdev @wuweiweiwu power move

fav part of tonight’s panel is @raunakdoesdev turning off the mic before passing it to @wuweiweiwu every time
