Founders of Science Exchange, Goldbely, and The Flex Company Discuss Fundraising

TL;DR

Three YC alumni founders (Science Exchange, Goldbelly, The Flex Company) discuss fundraising across seed to Series C stages. The first check is the hardest; later rounds are easier due to traction and metrics. Pivoting from story-driven pitches to economic/business-centric messaging resonated better with investors.

Key insights

• The first check is the hardest check to close (rated a 9/10 difficulty); subsequent rounds become easier (~4/10).
• Pitching an emotional or use-case story (e.g., “NASA used our platform to create the blackest material”) fails; investors respond to market size, transaction cost elimination, and billion-dollar poten
• For niche or taboo products (e.g., period products), investors may deflect with comments like “let me ask my wife”; those are signals to move on rather than pursue further.
