What founders say
“We 5x'd revenue in the time I worked with Frankie. … Pricing, hiring, expansion calls I used to sit on for weeks get resolved in one conversation.”
“In a three-week sprint, Frankie narrowed our ICP, coached me through my first enterprise sales cycle, and helped us book 30+ targeted conversations. Two weeks later: four VC term sheets.”
Let's find a way to work together.
Open for founder and cofounder coaching.
AI agent and fractional engagements are booked; new openings from Q1 2027.
