P&L test for investing in sales tech

Jason Gelman’s Background

Jason Gelman is a Go-to-Market Operating Partner at Primary Venture Partners, one of the largest early-stage VC firm that just closed its $625 million Fund V (the largest to date) a few days ago, bringing total AUM to ~$1.6B.

Before Primary, Jason led Revenue Strategy & Operations at Compass, helping scale the company from ~$100M ARR to $6B through their IPO. He got his start in the New York tech scene after attending law school, where he quickly realized the meritocracy of tech was a better fit for him than the rigid hierarchies of the legal world. He’s never looked back.

At Primary, Jason has built out two core programs for portfolio companies: a Market Development team (centralized BD outreach on behalf of founders) and a Go-to-Market Engineering program (tech stack buildout and systems architecture). He's also leading the development of the firm's investment thesis around go-to-market tech.

Discussed In This Episode

• How Primary's portfolio support model actually works and why "advice-giving" doesn’t cut it

• The Market Dev team's unfair advantage: why outreach from Primary converts better than any vendor pitch

• The Go-to-Market Architect role: why it's different from a GTM Engineer (and why Clay's definition falls short)

• Why a profile with deep experience in legacy SaaS tools + fluency in modern AI will easily earn $500K to $1M+/year

•How to find the rare 3-in-30: RevOps chops + AI fluency + business acumen

• The Full Stack GTM person: one role replacing marketer + SDR + AE

• How the PNL test should filter every sales tech investment and why the old "time savings" ROI story is dead

• Where Salesforce is headed in the next 10 years and why its pricing leverage is finally at risk

• Why Slack might be Salesforce's best asset going forward

• Small teams doing massive revenue: what $1M+ IRR per employee actually looks like

• How to break into VC from a go-to-market background
