Cellular covers about 15% of Earth's landmass. Everything past that has meant hardware too expensive to justify tracking. Today, we're opening satellite coverage to Bluetooth devices, plus a $200M Series C, crossing unicorn valuation. @sana_pashankar at @Bloomberg has more.

Next year, we're going to launch a spacecraft that will be given zero commands from Earth after it separates from the launch vehicle. The spacecraft will attempt to complete all of its mission objectives with no human operator in the loop. Today we’re introducing Autonomy-1, powered by our spacecraft intelligence model, Solo. 🧵

Growth this year at @supabase has been wild. Each month I wonder if going to peak, and yet the charts keep climbing What feels unprecedented is that all charts are trending up - even as sign ups grow, so does activation and conversion LLMs have changed the game - not only are there more builders than ever, they are able to build easier and get to a functioning app faster. It’s never been a better time to build

Pretty surreal seeing our name (and new branding) in lights last week. Thank you @NYSE for the recognition. Ad astra!

We're excited to announce that we're going to be joining Y Combinator in Fall 2026. The team is super pumped to be working with @golda and co to continue on our journey of creating the best in class open source models for agentic commerce.

Today, Stoke announced a $1 billion Series E, bringing our total capital raised to $2.3 billion. This funding will help us bring Nova Pathfinder to flight, accelerate development of our larger 15-ton-class Nova Block 2 vehicle, and build the production capacity required to fly at scale. This milestone reflects years of extraordinary work by the Stoke team and the conviction of customers and investors who share our belief that fully reusable space transportation is both possible and necessary. We are deeply grateful for their trust, and more energized than ever by the work ahead. Read the full announcement: stokespace.com/news/stoke-sp…

the top 3 frontier labs are now all run by YC founders

Apex is The Spacecraft Platform Company. For most of space history, progress was measured in firsts. First satellite. First human in space. First Moon landing. The next era will be measured in rate: how fast you can deploy, replenish, and refresh the infrastructure everything else depends on. That’s the New Space Race. Winning it takes constellations: many satellites working together as systems. And constellations require two industrial capabilities: launch and spacecraft platforms. Launch is ready enough. Platforms are not. Apex exists to remove that bottleneck.

Signups are now open on Code[dot]Storage. Today, more new repos are created per second on Code Storage than any other platform. Lovable, Bolt, Amp, Poke, and many more of the largest agentic workloads store their code and agent memory at scale using Code.Storage.

On August 12, @heartaerospace flew the world’s largest electric aircraft. piped.video/watch?v=fEudbAjs…

Supabase is now deploying >1m new Postgres databases every week & that doesn't include read replicas

We’ve decided to open-source a multi-agent harness we use internally at YC. We call it “QM” and it’s meant to be easy to customize, like Hermes or OpenClaw, but useful for a whole company. We use it across accounting, legal, events, and engineering (including building QM itself!). The whole project is under an MIT license. It is cloud-first and has Slack and web UI natively.

Kimi K3 is now available on Ollama’s cloud. To use it with Claude Code, run: ollama launch claude --model kimi-k3:cloud Currently Kimi K3 requires a Pro or Max subscription, and consumes extra usage credits. We’re quickly working on adding capacity to expand access.

Software engineering is becoming a hierarchy of loops. So today we're launching Mastra Factory: a system for agents to take software from issue into production. Get started with 𝚗𝚙𝚖 𝚌𝚛𝚎𝚊𝚝𝚎 𝚏𝚊𝚌𝚝𝚘𝚛𝚢:

The goal of Y Combinator has never been scarcity and that's implicit in the name. We think there should be more startups in the world, and YC exists to help create them. There are far more people who can, should, and will be in the arena. So yeah, we rented out an arena.

YC Startup School 2026 just got going 3x bigger than last year We made this event for first time very technical young people to come to SF and figure out if starting a company is for them Let you in on a secret: it is

AI is moving into the physical world. We're excited about a new wave of startups rebuilding the systems that power the real world, from education and healthcare to defense, finance, infrastructure, and work itself. ycombinator.com/rfs

Today, we are announcing H1. H1 is a model developed by @HandoffAI that performs autonomous construction takeoffs at the level of a human estimator. This is an incredible accomplishment for our team that has been in the works since we started the company in 2019. I also believe that this is a monumental step forward for the construction industry as a whole. Why does this matter? Until now, reading a set of construction drawings and extracting a detailed understanding of how to build a project required a human. That is what a takeoff is. H1 automates this process entirely, meaning that any construction drawing can now become machine-readable. With a single API call, you can accurately extract all of the characteristics of a building, including detailed material quantities down to every single stud and nail. Combined with Handoff’s existing AI estimating models and live construction cost data, this also means that every construction drawing can become an accurate construction budget, with materials that can be purchased directly through our supplier partners in just a few clicks. From the early days of Handoff, we said that we were codifying the language of buildings and developing an abstraction layer that would enable anyone to interact with construction blueprints as if they were structured data. This is no longer a demo. H1 is available to thousands of construction companies on the Handoff platform, as well as at thousands of Pro Desk locations across every US state. In addition to announcing our model, we’re publishing a research paper that describes how we built it. We’re also open-sourcing the benchmark we use to validate that Handoff outperforms every foundation model, as well as human estimators, on a set of permissioned construction blueprints. If you are a construction supplier or an enterprise looking to integrate AI takeoffs into your systems, please don’t hesitate to reach out to me and we’ll set you up with access. Let’s build something great.
