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 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. 💪

Humans make billions of calls every day. AI voice agents will perform a majority of these calls. Ensuring their reliability is tough — small changes can break responses, and manual testing doesn’t scale. Even when you ship your voice agents to production, teams spend hours manually listening to calls to find bugs and edge cases.
At @HammingAI, we automate testing, monitoring, and governance for Voice AI agents, helping teams catch failures, optimize prompts, and flag edge cases in production. Hamming makes your Voice AI agents trustworthy.
Thanks to our team, customers, and investors for believing in this mission.
🚀 Founder’s Day Tokyo kicks off with @garrytan, CEO of @ycombinator!
💡 Key insights:
1️⃣ People + Culture drive success – build what people want.
2️⃣ Resilience wins – success takes time; persistence pays off.
3️⃣ AI will create thousands of unicorns, and Japan will lead.
Thank you, Garry, for inspiring founders to think big! 🌏
