For venture firms
Beyond the check. Real revenue growth.
Capital and a network aren't enough anymore. The firms that stand out help their companies execute, scale, and earn the next round. I'm the go-to-market operator who does that work inside your portfolio. I've done it before as a GTM advisor to the Andreessen Horowitz portfolio.

Who it's for
Firms without a full-time operator, and firms whose operators are stretched.
I partner with GPs as a fractional GTM operator across the portfolio. We agree on which companies need help and what outcomes matter, then I roll up my sleeves and get to work.
Most of your founders are brilliant builders who have never run a sales process. I meet them where they are, build trust fast, and work in the trenches with them: market strategy, pipeline, deals, hiring, and getting investor-ready for the next round.
How it works
One operator. Your whole portfolio.
Align with the GPs
We prioritize companies by stage and need, and set clear goals for each: first repeatable deal, first sales hire, or a credible plan for the next raise.
Work hands-on
Embedded time with priority companies, plus workshops and office hours for the rest of the portfolio, so every founder gets something useful.
Report back
Structured, consistent feedback to the partnership: what's working, where each company is stuck, and what it needs next.

Nick CanditoCo-Founder & Managing Partner, ACOFI've had the pleasure of working with Justin for over 15 years and have watched him work side by side with founders to scale their sales machine.
