Today we’re announcing our pre-seed round and a new product: @starslingdev Review Runners - code review agents that use your model key, your team’s skills and scripts, and reviewers you define, all running in GitHub Actions. We’ve raised $3M from @BessemerVP and @ycombinator to make code verification agent-native. code → verification (ci + code review) → production

Introducing Superset for iPhone. Remotely control agents running on your computer. Review and ship PRs from your pocket.

Our third agent skill is live! Check your repo's GitHub Actions for 10 attack vectors that all map to public security incidents. npx skills add starslingdev/skills

The latest version of hpc-sandbox-benchmarks is live! We’ve added 5 additional sandbox providers: @microsandbox @namespace run.cloud @RunloopAI and @vercel Today we’re also releasing an interactive results explorer that allows you to cut the data across the benchmarks to see p50, p95, and specs for CPU, disk I/O, memory, network, etc. Try out the explorer, we’d love your feedback! And keep the PRs coming :) starsling.dev/hpc-sandbox-be…

Today we shipped sling, an agent-first CLI for your GitHub Actions 💫 Right now, if you ask your agent why a CI job failed, it goes and pulls the entire set of GHA logs and eats up your context window. 🪵 > sling why @starslingdev computes the run's logs and metadata, along with the evidence lines it matched to tell you why a run failed If you want to know what your GHA usage is, you have to go to the GH UI and click around to find it. 💸 > sling bill tells you how many minutes, how much you're spending, and across which runner labels Trying to understand what your slowest job is? You'll need to hunt around the GHA UI and even then you only get an average. 📊 > sling top and sling usage tell you runner minutes and cost across all workflows and repos, with p50, p95, p99, queue wait and a week over week trend starsling.dev/cli

The benefits of AI are dangerously concentrated. Today they accrue to a handful of labs and to one industry, software, whose work happens to look like the internet the models were trained on. Changing that is the single biggest untapped lever for economic growth this decade.🧵

Introducing Yutori Navigator 31 years ago, the modern web era began with Netscape Navigator. Today, we’re introducing Yutori Navigator — a web agent that autonomously navigates websites on its own cloud browser to complete tasks for you. Navigator achieves pareto-domination over Gemini 2.5, Claude 4.5, and OpenAI Operator • 10%-20% accuracy gains across benchmarks • 2-3x faster • Uniformly preferred in head-to-head human-evals Simply put, the best web agent in the world

Excited to announce the release of Westworld v1: A suite of highly realistic browser simulators with verifiable rewards for web agent benchmarking and RL

We’ve raised $5M in seed funding to power this journey, led by @HivemindCap , with participation from @cbventures , @alliance , @transposevc , @Polymorphic, @Tykhe_Ventures , and @ContributionCap . And today, we’re opening up our new site → zynk.money

announcing @adamdotnew’s $4.1m seed round, to build the future of cad we’re hiring.

We just raised an $11M seed to help developers build complex agents across any model and any tool in 5 lines of code. Our round was led by @KindredVentures (@stevejang) and @saga_ventures (@maxaltman, @braveben, @itsthomson). At @DedalusLabs, we believe the future of AI agents isn’t linear or deterministic. Agents should know when to stop, when to branch, when to reattempt a task, and when to pause and ask for context. As a developer, we make your job simple: define the prompt, select the right tools and guardrails, and let your agent run. We were tired of writing hundreds of lines of code and battling Dockerfiles and infra—all for a spaghetti agent that breaks under stress. With Dedalus, you don’t have to do things the hard way. Our open-source SDK supports vendor-agnostic model handoffs, chaining both local and hosted (MCP) tools, and streaming across any provider—all in 5 lines of code. Plus, our cloud infra lets you deploy an MCP server in 3 clicks so anyone can equip their agent with your tools. Let us do the heavy lifting so your agents can fly 🪽 Thank you to our incredible team and our early supporters: @c10n, @habibh from @e14fund, @YazanElBaba from @emergencecap, @donnystalter from @SunshineLakeVC, @karrwinn from @transposevc, @liquid2V, @fpvventures, @forwarddeploy, @AntWilson, @iamcal, @Thom_Wolf, @ashtom, @HazanPrinceton, @tri_dao

We’re excited to launch Dedalus Labs, an AI-native cloud platform for developers to build agentic AI applications. Connect any model to any MCP servers, local or remotely hosted by us, and build complex agents in 5 lines of code.

🚀 Huge congrats to the @trycua team — #1 trending on GitHub today! Incredible to see the momentum behind open-source infra for AI agents, and awesome to share the leaderboard with fellow YC alums. 👏 Always proud to back builders like this. 💪 cc: @francedot

Introducing slate. Slate is an agent built for long, hard, and edge-case coding tasks. Useful for: - Large scale migration work - Debugging systems end-to-end - Full feature development - etc. Now available. 1 month free. Link in bio.

Big news: Hubble Network has raised $70M in Series B funding, $100M total to date! With 7 satellites now in orbit, we’re making it possible for billions of Bluetooth devices to connect directly to space, no cell towers, no gateways. 🚀🚀 Details: payloadspace.com/exclusive-h…

日本はAI×ヘルスケア・介護分野で世界をリードできるポテンシャルがありますが、グローバルに挑戦する人材はまだまだ不足しています。 JIC、@transposevc、@IVS_Official主催のウェビナーでこの課題について、起業家の皆さんと率直に語り合うのを楽しみにしています！ 👉 lu.ma/at64xilf
