Sentra

We beat Mythos and Fable 5 in <36 hours. There's been endless hype around Mythos' capabilities since its announcement, so much so that Anthropic won't release it directly and instead publicized Fable 5, a safety-capped version of the same model. So once Fable 5 was out, we @sentra_app knew we had to test just how wide the gap was between it and what was already available. We took GPT-5.5, the current leading model on Terminal-Bench 2.1, and changed one thing: we gave it Sentra's Code Memory. The result: - A score of 88.31%, ahead of Fable 5 (80.5%) and Mythos 5 (88.0%). - 3.65x cheaper than the same model without Sentra. Accuracy up, cost down ~72.6%, tokens down 41.2%. All from one change: a task-scoped memory layer that keeps the agent from re-reading context it already has. We're now submitting through Terminal-Bench's official verification and will release every agent trajectory once verified. Benchmarks on @datacurve DeepSWE are coming soon.

Looking to hire senior engineers. After our recent benchmark post went viral The waitlist and hype for the @sentra_app code memory launch have gone out of control, and we need more talented engineers so we don't die.

Andrej Karpathy, Cofounder of OpenAI, now at Anthropic, on why agents are still a decade out from being useful. Every conversation starts at zero tokens. Restarting from scratch, every single time. Agent memory and organizational memory are the same problem. Success with AI in the next decade relies on solving it.

Brian Chesky, CEO of Airbnb, on why he reviewed every detail of his company for two years straight. 100-hour weeks. Just to know what was happening. Visibility is the foundation of leadership, and will always be the most expensive function to maintain by hand.

we just built yc's request for a company brain. not a knowledge base, but real memory that both humans and agents can interact with, with a full understanding of every interaction, decision, and commitment your team has ever made. we're currently onboarding select teams.. dm if interested!

What does it mean to have organizational memory?

@ashwingop is that @PalmerLuckey ??

We've raised $5M to build organizational memory. Every company runs on decisions, but as teams grow the, context behind them gets lost. We built Sentra to make sure that never happens again. Start using Sentra for free today!

Infinity used to be a philosophy problem. Then we built machines that think, and now infinity is in your face before your first cup of coffee. How do you know what actually deserves your attention right now?

Every conversation, decision, and debate your company has today is context you’ll wish you had tomorrow. Most companies let it evaporate. The best ones are starting to capture it. @sentra_app is building the essential memory infrastructure for them. @Forbes wrote about what we’re building. Read below 👇

Today, I’m excited to announce that @sentra_app has raised a $5M Seed. This round is led by a16z @speedrun and @scaletogether, with participation from @parable_vc, @ekaurghar, @PrecursorVC, @inovia, @BackwardsCapVC, and @AntigravitySF. We also have some of the best founders and operators backing us - @gokulr, @blader, Prasad Chintamaneni, @cailen, @KaitlynKnopp and more. @ashwingop @AndreyStarenky @alrey_ and I are tackling the unavoidable problem every growing company struggles with: context decay. When you're 3 founders, everyone knows everything. But scale to 50 or 100 people over a few months, and it gets hard to even know everyone's names, let alone stay in sync. People stop knowing why decisions were made. Or worse, people stop knowing what was decided at all. Context all too often stays in people's heads, never written down. At large companies, it gets very expensive. One leader told us their engineering team wasted a month building support for a feature that another team had already deprecated–nobody told them. Today, we try to prevent it with more documentation, more meetings, or more tools. But none of those really work. You drown in bureaucracy while tracking everything about what happened and nothing about why. Sentra does something that wasn't possible until now: it builds a living memory of your company as work happens. Not just what was decided, but why, what alternatives were considered, and how decisions connect across teams and time. What does that actually mean? Leaders get a weekly synthesis of where teams are drifting and what needs attention. New hires ramp in days instead of weeks because "who do I ask about X?" has an answer. Status updates and decision logs are automated–no more chasing people. Today, Sentra’s been deployed in dozens of companies all the way from Seed stage to Global Fortune 500 enterprises. Finally, a massive thank you to our early believers - @anneleeskates, @ekaurghar, Chuck Dietrich, Alex Yang, @tllshankar - to name a few, for their support and guidance from the earliest of days.
