Irina Denisenko
Irina Denisenko is the co-founder and CEO of Knox Systems, an Austin-based cybersecurity company that delivers 'FedRAMP as a Service' to help commercial software vendors get authorized to sell to the U.S. government in roughly 90 days instead of years. She started Knox in 2023 after living through the FedRAMP bottleneck herself as COO of Class Technologies, where she scaled the company to $50M in ARR. A repeat operator who also helped build drone company PrecisionHawk, Denisenko positions Knox as a challenger to Palantir's FedStart, backed by Felicis Ventures and roughly $31.5M in total funding.
Charles Packer
Charles Packer is the co-founder and CEO of Letta, the San Francisco startup building the memory layer for AI agents. He is the original author of MemGPT, the viral research project that reframed large language models as operating systems that manage their own memory. A UC Berkeley computer science PhD out of the BAIR and Sky Computing labs, Packer walked away from offers at OpenAI and Google DeepMind to build stateful agents that remember, learn, and improve after deployment - the layer he argues sits above the base models and separates a real agent from a chatbot with a nice interface.
James Detweiler
James Detweiler is a General Partner at Felicis, the venture firm behind investments in Shopify, Fitbit, and Twitch. Promoted to General Partner in February 2026, he has sourced, led, or co-led 25+ investments across AI, robotics, vertical software, and defense - including Skild AI (now valued at $14B), RunwayML, and Mercor. A summa cum laude Dartmouth grad in Physics and Mathematical Finance, he honed his AI investment lens at Zetta (the first AI-focused venture fund) and SVB Capital before joining Felicis. He founded the Felicis Fellows program to bridge top AI researchers and entrepreneurship, and coined the investment thesis 'The Great Splintering' - the idea that as thinking becomes cheap, value shifts to trust, judgment, and presence. He grew up in Santa Clara as the youngest of five children of an actress and a painter.
Renata Quintini
Renata Quintini is a Brazilian-American venture capitalist and co-founder of Renegade Partners, a $228M early-stage VC firm she launched in 2020 with Roseanne Wincek. Known for coining the 'Supercritical Stage' - the critical post-product-market-fit phase before full-scale growth - she brings two decades of investing experience from Felicis Ventures and Lux Capital, where she backed companies generating over $40B in enterprise value at exit, including Dollar Shave Club, Cruise Automation, Warby Parker, Wise, and Glossier. A Stanford-trained lawyer and MBA, three-time state karate champion, and Bossa Nova guitarist, Quintini is one of the rare women who runs her own venture fund.
Sundeep Peechu
Sundeep Peechu is a Managing Partner and founding member of Felicis Ventures, one of Silicon Valley's most consistent early-stage VC firms. A former IIT Madras engineer who went through Intel before pivoting to venture capital, he has backed transformational companies including Plaid, Canva, Notion, Cruise, Runway, and Mercor. Known for a decade-plus holding philosophy, hands-on founder support, and a particular obsession with AI and health tech, he has helped guide Felicis from a $41M debut fund in 2010 to a $900M Fund X in 2025.
Victoria Treyger
Victoria Treyger is a Senior Venture Partner at Felicis Ventures who spent 17+ years as a hands-on operator before crossing over to VC. She scaled Kabbage from a startup to nearly $300M in revenue across six straight years of 100%+ growth before its $850M acquisition by American Express in 2020. At Felicis, she backs fintech, SMB software, and health tech founders with the tactical depth of someone who has actually done the job.
