4 years of building. 3 years of no traction. 2 years of moving to Malaysia to reduce burn. 1 year of insane growth. Now at $200K MRR!

Smithery just launched Toolbox 🧰, a single MCP that dynamically routes to all 4000+ MCPs on our registry based on your agent's needs! Your agent can now use multiple @SmitheryDotAI MCPs without knowing which ones are needed in advance: 👇

Smithery instantly adds thousands of hosted MCP servers via a single link. Use @ExaAILabs and @browserbase in @OpenAI's new responses API playground.

After 6 years, it's a bittersweet moment for me to share that I've exited from Jenni! Building my startup from $0 to $6M ARR has been the craziest adventure of my life. I've learned so much and made many friends on the way. I'm proud of what our team has accomplished. My

Taken to the limit, AI coding is perhaps more akin to an advanced compiler. Compilers take high level code and turn it into low level instructions. AI compilers do the same but take natural language or human goals as input.

The story of how one Chipotle burrito 🌯 led me to co-found a $6M+ ARR AI startup: I started my freshman year and met @Davidjpark96 because we were both looking for roommates. We met up at a Chipotle near campus. We made our order (no guac), sat down, and talked about our

I'm incredibly excited to be joining forces with @kamathematic as co-founders to build the new agentic internet, one where tool calls are the new clicks!

📢 I'm cofounding @SmitheryDotAI with @Calclavia. In a world where no single model has all the answers, agents need a platform to access capabilities and context at scale. We're fixing this with a cohesive gateway to discover and distribute intelligence. Memo in thread 👇

I'm hiring founding engineers to join Smithery to build the AI gateway of the future. We're currently a team of 2 and the leading MCP platform. Our usage grew by 20x over the last few months. If you're obsessed with connecting agents to everything, let's chat!👇

Watched @karpathy's talk on the State of GPT. The most interesting slide was how LLMs learn a spectrum of performances, and you need to ask LLMs for good performance. Feels similar to Upside down RL (arxiv.org/abs/1912.02875) where you sample trajectories from desired rewards.
