Follow me @samirkaji for my thoughts on the venture market, with a focus on the continued evolution of the VC landscape.

Welcome to another episode of Venture Unlocked. In this episode, I had the pleasure of welcoming Villi Iltchev, founder and managing partner of Category Ventures. Villi has had a long history in tech, both in operating roles at companies like Box and Lifelock, as well as investing roles at August Capital and Two Sigma, where he departed in 2024 to launch Category Ventures.

We covered a lot of ground in our conversation, including his inspiration for starting a new firm and the experiences that informed his true north. We also spoke about the fragmentation of the market and what it means to win in early-stage investing in a heavily crowded market of dedicated seed funds & larger funds who are active in see and Series A. I really enjoyed the authenticity of the conversation and hope you do as well.
