everyone at WarpStream sells, but @turbopuffer takes it to the next level the employees will look you in the eyes at a dinner party after just meeting you five seconds ago and ask “does your company puf? should you be puffin’?” with a completely straight face

I can’t stress enough how little an idea matters compared to the agency of the people executing the idea. I have had the privilege of knowing and sometimes even working with some of the most successful people (by various metrics). The difference between mediocre and excellent work and outcomes is predominantly one of agency. In practice this means: they dont wait for things to happen to them they go out and make things happen for them. They don’t wait for someone else to do something, for someone to teach them, for someone to give them the path, etc. They just go out and find a way to do it. I think the single biggest superpower these people have is the realization/belief that the world around them is completely mutable. Most everything that happens is because a person made it happen. I used to tell people to look around the room you’re sitting in. Look at everything. Every noun. It almost all exists because a person willed it into existence. Nothing is stopping you from doing the same. I see people online all the time dismissing someone else’s success because “I had that idea first” or whatever. I mean… yeah? If so then the difference is… you. So a bit of a self own whenever I hear that. Number one tip: act with agency.

i’ve had jobs where teams just accepted that 500s were a thing that happened (potentially correlated with ex-googlers) but nope, we will page an operator at any time of night if our application returns a single 500 error. 500s are for real problems which either indicates an incident starting or a bug that needs to be fixed completely aligned with tpuff
our goal is "no 500s ever", but if that ever slips we do the next best thing!

Got a note from the @turbopuffer team that they were seeing 500 errors on a small number of our requests and they would investigate. Found the issue, patched it, and shipped it to prod. Continually impressed with their team. Can't think of another vendor has been so proactive

turbopuffer crossed $100M run-rate in March. 19mo after $1M. Profitable & <$1M raised. Cursor・Anthropic・Notion・Cognition・Harvey・Bridgewater・Ramp・Linear・Legora・Superhuman・Atlassian・Granola We’d be nowhere without them. We work like hell to exceed their expectations.

SID-1 is an agentic search model by @SID_AI → 1.9x recall over RAG + rerank → 24x faster, 99% cheaper than GPT-5.1 trained using large-scale RL on turbopuffer at 1k+ QPS bursts over 10M+ document corpora across thousands of steps tpuf.link/sid-1

Starting to map the graph for a founding engineer at Perfloop. Looking for real systems depth - perf, infra, observability, AI infra, devtools, databases, runtimes - plus extreme agency, product/architecture judgment, and native agentic building. Europe / near-Europe overlap preferred.

1/ When we launched Notion AI Q&A in Nov 2023, we knew we were embarking on an ambitious journey. What we didn’t anticipate was how quickly we’d need to scale—or how much we could optimize costs. Notion vector search over the past 2 years: 10x scale, then 1/10th cost. 🧵

we’ve reduced query prices by up to 94%, thanks to infrastructure improvements we've made under the hood puff harder, for much less

what if we dove into search infrastructure together under the fish?

yesterday: short human queries, scalar CPUs today: long LLM queries, wide SIMD lanes for FTS v2, we use a vectorized MAXSCORE algorithm instead of WAND, because dumb & serial beat smart & random algorithms on modern CPUs tpuf.link/maxscore

I think turbopuffer is about the best name for a tech company that I’ve ever come across
turbopuffer the fashion brand might become bigger than the database
