E219: How Emerging Managers Can Beat Multi-Stage Firms

37 minutes

How do you underwrite pre-seed founders when the only durable asset is the human—before there’s product-market fit?

In this episode, I go deep with Mike Ma, Managing Partner at Sidecut Ventures, on his 30-day “work-alongside” diligence, why he optimizes for action-oriented self-awareness, and how to calibrate coachability—especially in go-to-market—without overfitting to investor bias. We unpack earned secrets, impact theses in education, climate, healthcare, and economic mobility, solo-GP advantages, alignment pitfalls from 2021-era rounds, and the mindset habits he wishes he’d had earlier: “write at a fourth-grade level” and “document your screw-ups.”

Highlights:

The 30-day “grind with them” model: watching founders operate to reduce storytelling bias.

What predicts pre-seed survival: action-oriented self-awareness (execute fast and integrate feedback fast).

Coachability, defined: focus on go-to-market (not deep tech) and respond to market-generated feedback.

Earned secrets: the unfair advantage born at the intersection of novel markets + lived expertise.

Why solo GPs can be more aligned: speed, conviction, and operator empathy at pre-seed.

Valuation ≠ victory: how 2021-style prefs/marks can zero founders despite solid outcomes.

Two habits for builders & investors: write simply and log your mistakes to kill self-deception.
