Justin Liu and I are excited to announce Charta Health’s $22M Series A, led by Bain Capital Ventures, with participation from Madrona, SV Angel, Refract Ventures, South Park Commons, and strategic angels. This brings our total funding to over $30M. When we started Charta, we saw a major gap in healthcare infrastructure: billing and coding workflows - a process that touches hundreds of billions of dollars in healthcare - was still largely manual, slow, and error-prone. Most charts go unreviewed before billing, which leads to missed revenue, preventable denials, and unnecessary risk. Our mission was simple: if we could apply bleeding-edge AI technology to the pre-bill process, we could not only recover massive revenue but also improve care quality and reduce administrative burden. That’s exactly what Charta now does. Our platform reviews every chart before submission in real time, flagging missed codes, identifying patient care gaps, improving revenue integrity - all without disrupting existing clinical workflows. I’m incredibly proud of what our team has built - and deeply thankful to our early customers, advisors, and partners who’ve believed in the vision and trusted us to execute. A special thanks to those who’ve supported us: ✅ Aaref Hilaly and Alysaa Co at Bain Capital Ventures ✅ Kerry Kellogg, Ayokunle Omojola and Caesar Djavaherian at Refract Ventures ✅ Karan Mehandru and Sabrina Albert (Wu) at Madrona ✅ Ruchi Sanghvi at South Park Commons ✅ Mike Sho Liu at SV Angel ✅ And so many other operators and angels who’ve rolled up their sleeves with us - offering insight, time, and real conviction along the way. 💡 We’re especially focused now on growing our engineering team. If you’re excited to work on the hard technical problems that have real-world impact, and you want to help build a better system from the inside out, we’d love to hear from you. 👉 Roles are linked in the comments. Come build with us. Special thank you to Erin B. at Axios for covering the round!

I was honored to host a fireside chat with Clay Bavor, co-founder of Sierra (the AI-native startup recently valued at $10B), at last week's Fellows Forum 2025 organized by Fellows Fund. Before co-founding Sierra with Bret Taylor, Clay spent over 18 years at Google, where he played a pivotal role in shaping many of the company's most iconic products. His work spans from products at massive scale like Search, Ads, and Google Workspace (including Gmail and Docs) to pioneering projects in AR/VR and Google Lens. Most recently, he led Google Labs, which incubated next-generation AI applications like AI Studio and NotebookLM. It was incredibly inspiring to hear his vision for Sierra and the future of AI agents. His insights into the journey of building an AI-native company were particularly valuable, covering everything from the lessons he carried over from Google to the complexities of enterprise agents and Sierra's pioneering outcome-based pricing model. A few key takeaways: Lessons from his Google Experience 📍What he unlearned: Google's technology-first approach. In the enterprise world, you must start with the customer's problem. 📍What he brought forward: The ambition to build at the boundary of what’s possible and the importance of controlling your technological destiny through deep, in-house research. The Complexity of Enterprise AI Agents 📍The "Agent Iceberg": Clay described how the visible part of an agent is just the tip of the iceberg, with over 158 complex, unseen challenges below the surface - from latency optimization to release management. 📍Bespoke Voice Design: The platform supports over 34 languages and utilizes a dedicated "voice sommelier" to create custom voice experiences. Sierra's Outcome-Based Pricing Model 📍A True Partnership: Sierra only charges when its agents successfully complete a task, directly aligning its success with its customers' success. 📍Confidence in Performance: This model demonstrates deep confidence in the reliability and effectiveness of their AI agents.

Very excited to announce our investment in Charta Health today! At Madrona, we believe the most impactful AI companies don’t just speed up existing workflows — they reimagine them from first principles. Charta Health is building an AI-native platform that transforms chart review from a labor-intensive, error-prone process into a real-time intelligence layer — improving care quality, billing accuracy, and provider efficiency. Karan Mehandru and I have had the pleasure of getting to know founders Justin Liu, Scott Morris over the last couple of years and we’re thrilled to be partnering with them and the entire Charta team — alongside Bain Capital Ventures, SV Angel, Refract Ventures, and South Park Commons! More on why we invested below! 👇 https://lnkd.in/druSN-Na

We at Define Ventures have been believed in the impact and potential of AI from the very beginning, with the use cases spanning administrative efficiencies to improving the clinician experience. And our team has found a market eager to adopt AI as well: 75% of large payers and providers planning to launch AI this year. But building AI for healthcare isn’t just about having a great product—it’s about proving scalability and longevity. At Define Ventures, we’re focused on finding and supporting founders with the vision and execution to deliver on this promise. The surge in health tech AI funding is just the beginning. Thanks to Mario Aguilar for a great conversation on this topic https://lnkd.in/gkB6RXeJ
