Co-Founder and Part-Time General Partner
CoalitionCheck size: $500K target investments, as published by Coalition.
Lindsay Ullman invests or supports investments through Coalition's published strategy: Back founders taking large swings at important problems, pairing a $500K early check with practical support from active founders and operators.
Founders with a deep personal why, unfair insight, exceptional competitiveness and strong founder-problem fit.
No categorical sector exclusions are public. Weak founder-problem fit, limited ambition or a lack of intense commitment run counter to the stated criteria.
Make the founder-problem connection unmistakable, show the unfair insight and early momentum, and ask for the specific operator help that can remove the next bottleneck.
