What we learned from B2B Marketplace YC applications

“You have 2 customers and $5.67 in revenue, one trading bot is 90% of your business, that's not a category yet.”

7.7/10·Real organic pull from agents is phenomenal for 5 weeks, but next 60 days must prove this scales beyond one lucky customer.

“Solo founder, part-time, few weeks in, no users, no revenue, no GTM plan for the brutal marketplace cold start problem”

6.5/10·Huge market and sharp vision, but needs to prove she can ship fast and solve two-sided traction before competitors move

“Five users in five months with zero revenue is not product market fit, it is a friends and family beta.”

5.3/10·Real pain point and credible wedge, but execution is too early and too slow to be compelling yet.

“You built a marketplace and only built one side, zero corporate buyers will route ESG budgets through your unproven crypto tokens.”

6.6/10·Rare builder who shipped working tech fast, but you are aggregating supply no one has agreed to buy yet.

“You are building a POS feature that will get commoditized before you prove the marketplace works.”

5.2/10·Real hustle and domain knowledge, but you need 50 active buyers and recurring revenue to prove this scales.

“You have 4 customers from your dad's network and no plan to get the next 50, that is not a GTM strategy, that is a warm intro.”

6.3/10·Real revenue in 3 days is impressive, but go full time, prove you can sell cold, and ship actual software or this dies.
