Mark Goldberg is a Managing Partner and Co-Founder at Chemistry, a new early-stage venture firm with a $350M debut fund backing standout software companies from Seed to Series A.

Before Index, Mark was one of the first business hires at Dropbox, helping the company navigate hypergrowth.

Discussed in this episode

Hiring strategy: network access > spreadsheet diligence
Culture principles: excellence, performance, “no one takes themselves too seriously”
Conviction-based investing vs consensus IC, and why omissions are the real killer
The hardest lesson in venture: managing co-founder dynamics (and when to just listen)

From starting as a small, operator-led rolling fund, to evolving to an institutional platform, AngelList has been a core partner in every phase of GTMfund’s growth. Their software-first fund admin infrastructure allowed us to scale without sacrificing agility — from onboarding hundreds of LPs seamlessly to handling compliance, capital calls, and reporting as our fund size evolved.

As we expanded from Fund I to Fund II, AngelList took care of the back-office operations, allowing us to stay focused on what matters most: investing in world-class founders and building the strongest go-to-market network in venture.

They’ve scaled with us across funds and into the future.
