I'm thrilled to announce @Stedi's $50m Series C, led by Lee Fixel from Addition with participation from @Stripe, @RibbitCapital, @USV, @FirstRound, @BoxGroup, and @BloombergBeta, along with angel investors including @tobi, Charlie Songhurst, @rauchg, @karimatiyeh, @Max, and more. This latest round brings our total funding to $142 million. We’ve grown enormously over the past year. Our number of paying customers has increased by 6x year over year, and our number of billed transactions has increased by over 7x. We’re now processing more than a billion claims and eligibility transactions annually – to frame this on a relative basis, we processed more transactions in February alone than we did in the first half of 2025 combined. This month, Stedi was named one of @TryRamp's fastest-growing vendors – across all categories, not just healthcare – for the second time in ten months; we’re the first non-AI company to make the list in five months. We’ve done all this while offering a level of support that (allegedly) doesn’t scale. We offer dedicated Slack and Teams channels to every customer and now have over 1,500 shared channels. Over the past 12 months, our median support ticket response time has decreased from 18.3 minutes to just 6.7 minutes, all while handling a 6.4x increase in support volume – with 100% of tickets answered by humans. Our customers send us thousands and thousands of questions and suggestions every month, day and night, and the learnings we get from this firehose of real-time feedback are the engine that turns our business. It is this process that has made us the fastest-growing clearinghouse by a wide margin. This latest round of funding allows us to continue to accelerate development across our platform and to continue to serve customers with a first-rate support experience. One key to that is continuing to build a world-class team – to that end, we are hiring for dozens of roles across engineering, product, design, operations, GTM, and more. If building the transactional layer for the future of healthcare sounds interesting to you, drop me a note.

We are thrilled to share that @jaltma is joining Benchmark as our newest General Partner. The Benchmark partnership is built on a shared commitment to the craft of venture capital, where our work is defined by the depth of service and commitment to the founders we work with. We believe this work does not scale and is best practiced where we win as a team of partners. By operating as a true partnership rather than a collection of individual franchises, we ensure that every founder we back benefits from our combined experience and a singular, shared commitment to their success. We first met Jack as a founder of Lattice over a decade ago. We followed Jack as he built Lattice into a leader in its category and navigated the turbulence that every software company faced in 2020. We admired Jack’s character and the way he prioritized transparency and authenticity to build a great team. That same value system defined his transition to founding a venture capital firm, Alt Cap, where he has made a familiar commitment to craft and service over capital. As an investor, Jack has partnered with some of the most ambitious founders of the generation with his investments in Legora, Rogo, Owner, Avoca, Rippling, and many others. Founders told us “I call Jack first to work through the toughest problems,” “He is my most trusted partner on the board,” and “Jack provides steady and grounded support that is rooted in having been a founder himself.” He combines relentless energy, deep intellectual curiosity, and a competitiveness to see founders win, all anchored by high integrity. We have always believed that our firm’s strength lies in its equal partnership: a small, focused group of individuals who operate with the same authority, responsibility, and singular mission to support entrepreneurs from the earliest stages. By joining our partnership, Jack brings a fresh perspective that will help us continue this mission. Welcome to Benchmark, Jack. – Ev, Chetan, Eric, Peter

Nvidia-backed startup Starcloud trained an AI model from space for the first time. Last month, the company launched a satellite with an Nvidia H100 graphics processing unit. Now, the company’s Starcloud-1 satellite is running and querying responses from Gemma, an open LLM from Google, in orbit, CNBC has learned. cnb.cx/3MEcWwt
