im 23, in sf for tech week, building agent swarms at acyclic (yc f26)
if you're here and building something real, let's connect
followers friday 🫡
went from ~430 to 606 followers this month, mostly from the demo videos. last few posts were mid ngl
building agent swarms at acyclic.dev in public, wins and Ls
if you're into agents, infra or evals, drop your handle below and i'll follow back (if you're not a bot)
flicked through one of my prs and found this
can someone explain how google's api keys actually work? GOOGLE_API_KEY vs GEMINI_API_KEY
and i can run gemini and gemma on gcp and on google ai studio. what's the difference, and why aren't they the same? (or are they?)

This is our YC launch.
I talk about armies of tiny servers.
you should watch it.
we are at the frontier but you can't use it cause we are pacing the frontier
Replying to @OfficialLoganK
Carbon is rolling out first to cyber defenders and we are working to make it more widely available soon!

here at @kaggle @GoogleDeepMind bench summit today
we're building benchmarks for swarm coordination, and for the pitfalls you hit when thousands of agents run at once
say hi if you're around
mocking tests is a problem which is getting bigger and bigger as products integrate with more and more apps and these guys are building at the frontier of the space, making it easier for everyone
Three months ago @ev_whitehouse and I set out to fix how agents get tested. Mocks aren't real enough and sandboxes don't scale.
Today we're launching Rystic (YC F26) : local copies of Slack, Stripe, S3 and the rest of your stack.
→ Save scenarios
→ Inject faults
→ Run at scale
Check it out below 👇
after the blacksmith raise, genuinely curious: what are people actually running CI on?
mine: blacksmith, 7/10. fast but expensive, even with the yc discount
it's 11pm on a friday in sf
everyone i know is out. i'm here with a whiteboard figuring out how to make 200 agents migrate a django app even faster than 49 minutes for $8
quit my cushy 6 figure job for this
late late night. who else is still building?
Demo #5: we pointed 200+ agents at a real e-commerce codebase and migrated it from Django 1.11 to 4.2.
Root → 15 orchestrators → one agent per file; 100s at once.
49 minutes. ~$8
Every transcript is public 👇

Shipping code shouldn’t mean hours of manual testing.
@Simulithic (YC F26) sends AI agents through your app like real users, across browsers, devices, and account types. It tells you what broke without you writing a single test script.
The teams that ship fastest will be the ones that can verify as fast as they build.
Get started today: simulithic.com
feels like everyone's token bills have crept up lately, curious where people are at
i'll go first: ~$3k/month, mostly on API and coding subscriptions. heavily subsidised by having way too many subs, one of my claude code plans burned the equivalent of $2.5k in API
reply with your spend (personal or company, ranges are fine) and what's eating it. coding agents, long-running agents, doc pipelines, something else?
230 agents running together rapidly to produce this exquisite rendering, check it out!
We gave blender to an agent swarm over just 15 minutes to create a complete model of an airship and this is what it achieved:
- 3 floors, 30 rooms and an exterior shell
- 4313 distinct parts and a 271 piece furniture library consisting of over 338k total triangles
- A rover hangar, drones, turbine hall, hydroponic garden, 3 distinct laboratories, an infirmary, radio room, a flight bridge
- Sleeping quarters, laundromat, communal mess, sky lounge (incl. musical instruments), library and much more
Resource usage:
- 230 agents
- 228 peak, 93 average CPU cores
- 2998 tool calls
Later this week i'll give it a shot at something photorealistic

Small businesses don't need a website builder. They need someone to do their marketing. They need Theo.
@theo_site (YC F26) is the AI agent that builds - or rebuilds - your site, then works 24/7 to get you found on Google and in AI search.
You run the business. Theo does the marketing. Free audit: theo.site

Demo 3: acyclic in 37 seconds.
npm install → sign in → describe the task. The swarm splits the work across agents in parallel, and one command applies the patch. Or let Claude Code drive it.
