The small and mighty team of seasoned experts building (and increasingly assisted by) Charlie.
Riley Tomasek — Founder & CEO
Riley sets Charlie’s direction and leads the architecture behind its agent runtime. He keeps the product thesis and technical core in the same loop, connecting models, tools, devboxes, reliability, and customer evidence. Before Charlie, he engineered at Dropbox, cofounded Flight, which was acquired by Figma, and founded Dexa AI.
Jerrod Engelberg — COO
Jerrod closes the loop between customer learning and company decisions. He connects trust, economics, positioning, and rollout to design partnerships, customer success, go-to-market, and operations. Before Charlie, he led Codecov through its growth from open-source roots to its acquisition by Sentry and worked in venture investing and company-building at FundersClub.
Ryan Eiger — AI Engineer
Ryan makes the hard parts of agent work coordinated, testable, and improvable. He turns ambiguous behavior and recurring production failures into systems for routing, durable tasks and mailboxes, evaluation, diagnostics, and optimization. Before Charlie, he worked on Google Cloud Storage, prototyped a code-generation tool with early access to Google’s internal language models, and led LLM applications to chip-design verification at ChipStack.
Bart Tyrpien — Product Engineer
Bart turns Charlie’s asynchronous capabilities into a product teams can see, understand, and control. He gives that work a clear path into the customer experience, from onboarding and integrations to Activity and the dashboard. Before Charlie, he worked in product engineering at Modulo and Kraken and on Caesars Digital’s online casino product.
