0-to-1 venture build
After years running fractional CMO engagements, the gap was obvious: clients needed something lighter than a fractional but more accountable than a favor. FOAF.pro filled it.
How David was engaged: Direct High Caliber AI engagement — David is the founder and operator of FOAF.pro.
David's work & commentary featured in
FOAF.pro stands for 'Friend Of A Friend, Professional' — a vetted network of senior execs available in fraction-of-a-fractional doses. It was born from pattern-matching across years of High Caliber AI fractional CMO engagements where the right answer wasn't 20 hours/week, it was 'the right person, fast, for a specific call.'
Stand up a credible new category from scratch: a brand, a vetted founding cohort, a way to match execs to client briefs, and enough early proof that the model worked at all.
Treated FOAF as a real venture, not a side project — brand, network, and operating motion in parallel.
Defined what FOAF was (and wasn't) versus traditional fractional placements and informal favors.
Brand, positioning, and site that signaled 'serious network' without 'overproduced'.
25+ senior execs in month one, 700+ combined years of leadership experience.
Ran multi-year client engagements off the network, validating the operating motion.
A working venture with paying clients, a credible founding bench, and a defensible position in the fractional-exec landscape.
