Competitive landscape

Edge: Crypto incentives + transparent scoring aim to solve evaluation data quality and provenance problems — a16z thesis that blockchains enable auditable reward markets for human feedback.

Model evaluation is bottleneck as labs proliferate. Yupp bets gamified consumer participation beats hiring labelers — but quality control is hard (a16z cites anti-cheating and zk research). Chatbot Arena is free alternative without token economics. $33M seed funds growth before proven enterprise data sales.
