This is an Open Coffee for Fractionals session — part of my coaching practice.
Ying Wang joined after a two-week grind chasing a timeout bug in DigitalOcean. The fix turned into a Michelin-star dinner for the engineer who stuck it out. She’s interim CTO for a mortgage tech startup, deep in B2B SaaS, and thinking about when to niche further — and when to shift from a single full-time client to a true fractional portfolio.
Matt DiBerardino came in mid-career transition, looking to figure out what “fractional” really means and how it overlaps with consulting. We dug into definitions, positioning, and why the label matters when you’re trying to be found.
We got into:
Noel Putaansuu brought live data from his smoke-measurement system — graphs for opacity and color shift — and the question of whether extra measurements matter when scientists only care about one. We talked about signal vs noise, what data actually gets used, and how you translate technical readings into customer-level value.
No slides. No pitches. No agenda. Just honest conversation.
