Alex Atallah, CEO of OpenRouter, on coaching, Stripe acquisition, and the future.

Who is Alex Atallah?

Alex Atallah is the co-founder and CEO of OpenRouter, the AI model marketplace, router and gateway. He grew up in Boulder, Colorado, studied computer science at Stanford and worked at Palantir before starting an NLP company in 2015. At the end of 2017 he co-founded OpenSea with Devin Finzer and was its CTO as it became the largest NFT marketplace, stepping away in July 2022 while staying on its board. He is based in New York.

Who founded OpenRouter?

OpenRouter started in early 2023 as the first LLM marketplace. Alex Atallah built the first version on top of Plasmo, the browser extension framework created by Louis Vichy, who reached out, started contributing code and became his co-founder; Chris Clark, previously co-founder and CTO of Grove Collaborative, joined as the third co-founder and COO. The company is headquartered in New York.

What is OpenRouter?

OpenRouter is one API for 500+ AI models from 80+ providers: it routes each request to the best model and provider for the task, handles fallbacks, cost tracking and enterprise controls, and publishes usage-based model rankings. It serves over 10 million users, with customers including NVIDIA, Lovable, Replit, Amplitude and NIST. Monthly volume grew from about 1 trillion tokens in 2024 to 12 trillion in 2025 and 450 trillion in October 2026.

How much funding has OpenRouter raised, and what is the Stripe deal?

OpenRouter raised a $40 million seed and Series A led by Andreessen Horowitz and Menlo Ventures in June 2025, then a $113 million Series B led by CapitalG in May 2026, with NVentures, ServiceNow Ventures, MongoDB Ventures, Snowflake Ventures and Databricks Ventures, at a reported $1.3 billion valuation. In August 2026 Stripe agreed to acquire OpenRouter; the company keeps its brand, team and roadmap.

Does Alex Atallah work with an executive coach?

Yes. Alex Atallah works with an executive coach from Titan, which matches Series A to C founders with coaches who have built or run companies at scale. He found Titan through a friend in 2024, and his co-founder Louis Vichy found his coach there as well. He credits coaching with sharpening the clarity of his thinking and with more optimism, gratitude and courage in how he looks at problems.

What does OpenRouter do?

OpenRouter is the first and largest AI model marketplace, router and gateway. The three things we help people with: observing, governing and managing all of their AI model usage for a large team; discovering new models that are good for their use cases based on the benchmarks and the real-world revealed preferences people have; and getting the optimal inference, the highest quality, best prices and best performance in the market.

What were the early days like?

In the early days of OpenRouter, it was just Louis and me and a community of LLM enthusiasts and a few developers who would really push the limits of language models on things they were not capable of doing. That is where all the magic happened. People doubted OpenRouter because they didn't believe a competitive marketplace would emerge. They thought it would be a one-model-win future, or one provider winning all the inference.

How big is OpenRouter today?

In the last three years we went from about 1 trillion tokens per month in 2024, to 12 trillion in 2025, to 450 trillion per month now. Today OpenRouter is 100 people with over 10 million users. We serve a lot of great customers, including NVIDIA, Lovable, Replit, Amplitude, NIST and many more, and we're hiring.

When did you start thinking about a coach?

Right at the beginning, right when I started. I believe you should always look for growth opportunities in life, and I can't think of a moment where it makes sense to stop looking for them. Coaching is a good way of finding them. I found Titan through a friend and started working with their coaches in 2024. Louis and I both found coaches through Titan.

Where has coaching helped you?

Coaching helped me refine the clarity of my thinking: reword ideas, resolve contradictions, resolve ambiguities, so that both my team and I understand what we're doing and why. If you're feeling it, chances are your whole team is feeling it too. And it really helped me find more optimism, more gratitude and more courage when looking at my problems. There is always room to go deeper on those three.

What would you tell other founders?

Finding coaches is really hard, and the cost of going through candidates that aren't a good fit is high. Titan does so much research and vetting on coaches, and when I learned how they find and vet new coaches it greatly increased my confidence. I strongly recommend Titan for founders who are building scaling companies, and especially for founders with a growth mindset.
