Hello, I'm Alex Kosik.

I’m a physician-turned-entrepreneur​,​ operator​,​ and investor who has spent the last 18+ years building​,​ scaling​,​ and advising technology companies across healthtech​,​ AI​,​ and deep tech. I’ve founded multiple companies​,​ served as COO and board member in venture-backed startups​,​ raised and deployed capital as a GP and angel investor​,​ and worked hands-on with founders navigating everything from 0→1 validation to 1→100 scaling. My background spans regulated and non-regulated markets​,​ including digital health​,​ medical devices​,​ AI platforms​,​ cleantech​,​ and consumertech. Founders typically work with me when they’re facing inflection points: sharpening product–market fit​,​ preparing for fundraising​,​ designing go-to-market strategy​,​ building execution discipline​,​ or making high-stakes decisions under uncertainty. My style is practical​,​ direct​,​ and outcome-oriented. No generic advice​,​ no theory without execution. I’ve mentored and advised over 1​,​000 founders globally and continue to work closely with early-stage teams as an advisor​,​ board member​,​ and fractional executive. I believe great companies are built by founders who think clearly​,​ move decisively​,​ and stay grounded in reality​,​ especially when things get messy.
