Building Lean: Lessons from a Solo GP and a Solo Entrepreneur
Early-stage startups raising under $10M are increasingly overlooked by large venture funds — and that gap has created space for a new model: the solo GP.
In this live, conversational webinar, we’ll explore how solo general partners are building fast, lean funds designed to serve founders earlier, move quicker, and win deals through relationships rather than heavy processes.
Join Alexander Bartolini, Solo GP and early-stage investor, and Sasha Batica, CFA, solo entrepreneur and operator, for an honest discussion on what it really takes to build — and back — companies in underserved early-stage markets.
We’ll cover:
Why larger funds have pulled away from small-ticket early-stage deals
How the solo GP model creates speed, trust, and founder-first alignment
What founders actually value in early-stage investors
The operational and fundraising realities of running a solo GP fund
How LP risk, continuity, and trust are addressed in lean fund structures
Whether you’re an emerging or solo GP, an LP exploring new fund models, or a founder navigating early fundraising decisions, this session will offer practical insights from both the investor and operator perspective.
