Darwinian Ventures

Darwinian Ventures is Andrew McGrath’s fractional CMO practice for AI-native startups at the zero-to-one and one-to-ten stage. Engagements are hands-on: positioning, outbound architecture, paid acquisition, content systems, and the weekly operating rhythm that keeps leadership aligned to pipeline. The practice exists to install durable GTM infrastructure, not to rent advice by the hour.
