Today we're launching @mastra `Harness` `Harness` gives you a `Session` with plan/build modes. It lets you manage thread lifecycle, spawn or fork subagents, approve tools per-call or session, ask user questions, queue/steer. With skills, sandbox, browser, heartbeat. channels:

there are now 10M developers using @supabase 3 million new developers in past 3 months

When YC bet on me as a founder, it changed the trajectory of my life. Grateful to be in a position to help founders who are just getting started!

Today we're introducing Slite as the first self-maintaining Knowledge Base Your wiki docs go outdated everyday, and your agents depend on them for your most ambitious workflows. Slite monitors your docs' accuracy from all other work tools (slack, jira, linear, codebase, etc) while you sleep and updates them. It even directly talks to your AI agents to give them accurate context without burning their context window or tool calls. You've been trying to build this 'company brain' for months now with hacky MVPs This is the final version of what you need, already built to be collaborative, headless, and secure. Check it out and HMU if you need this for your team, I'll be running personal onboardings for the next few days!

We are excited to announce that we have completed our 1st forward-flow loan sale of $8.5M with @3janexyz, a cryptonative credit protocol. This is the 1st phase of a broader $50M program and one of the 1st whole-loan purchases of a U.S. fintech loan book by a DeFi protocol.

Big tank. Big tests. Big milestone. Nova Stage 1 proto-qualification is complete. 46 structural objectives verified, plus key fluid systems, avionics, software, ground systems, and ops demos. (More detail in our linked blog post.) This is where new rockets often find the hard stuff; Nova (and the Stoke team) handled it. Our local partners at the @PORTOFMOSESLAKE , the Grant County Sheriff's Office and Public Works department, plus our vendor Norco made sure we had the support we needed every step of the way.

Walter (@walterindustry) is an AI employee for the manufacturing back office. He logs into the same legacy ERP a factory already runs just like a human would, and takes over the manual work no one ever wanted to do. Congrats on the launch, @nikolas_keller, @lukaspostulka! ycombinator.com/launches/Qdh…

Today we're announcing another $200M in funding at a $2.3B valuation to continue scaling the foundational layer of next-generation constellations: the satellite platform. For most of space history, progress was measured in firsts: first satellite, first human in space, first Moon landing. Those milestones mattered. But the next era will be measured in rate: how fast countries and companies can deploy new capability, replenish what is lost, refresh technology, and expand the infrastructure they depend on. To make that future real, the world needs constellations: many satellites working together as systems. That requires two industrial capabilities: frequent launch and rapidly manufactured satellite platforms. Apex exists to remove the satellite production bottleneck and unlock capabilities beyond what Earthbound systems alone can achieve. The strategy is simple, but difficult: own the world’s satellite platform category. Learn how this latest raise helps Apex make that a reality: apexspace.com/blog/apex-anno…

RASPIRE (@raspire_) is building app security at AI speed. As AI accelerates mobile attacks, their platform protects Android and iOS apps from fraud, reverse engineering, and API abuse with zero code changes. They're already securing apps used by 20M people across banking, fintech, and healthcare. Congrats on the launch, @EzV01d & @hsanmost! ycombinator.com/launches/QgY…

Supabase has raised $500M at a $10B valuation In this round we are giving @supabase employees the opportunity to cash out 25% of their vested options. We have done this in every round since inception. We do it as a “cashless transaction” so that employees don’t need to front any cash to exercise their options. This is the friendliest way we could design it until we can offer RSUs. On top of that, we give employees a 10 year exercise window: whether they stay or leave the company. The typical/default window is 3 months. IMO, equity is earned and employees shouldn't be penalized because they don't have the cash to exercise within 3 months of leaving a job (often that's the time they need the cash/certainty the most).

Opus 4.8 results are now on DeepSWE. Thanks for your patience. We wanted to it to be thorough and here are our findings. Deep dive on the results will drop in the coming days.

Empathy loop: think about the user and what they want, and give them it Conviction loop: believe you will create something of value for that user, even if most people think you won't

We raised another $106M at a $2.6B valuation since announcing our last round three weeks ago. Corgi has grown exponentially in the past couple of months, but we're only just getting started transforming one of the largest sectors in the US economy: insurance.
