About Dave Rubinstein

GTM Advisor. Founding AE Recruiter. 300+ founder conversations.

Who is Dave Rubinstein?

Dave Rubinstein is a B2B GTM advisor and Founding AE recruiter, and co-author of the SPRINT framework introduced in Harvard Business Review (June 2026) with Prof. Vincent Onyemah of Babson College. He was a Founding AE at ExpoTV, taking the company from zero to $10M ARR, spent six years in sales leadership at Salesforce, and grew a territory from $1M to $25M at Outreach. Today he works with B2B SaaS founders at $500K–$10M+ ARR, drawing on 300+ founder conversations across 40+ countries.

I built this practice by talking to founders constantly. What began as a public goal — 100 founders in 100 days — became 300+ conversations across 40+ countries, a pattern library for what actually stalls early-stage B2B revenue, and what fixes it.

Before this, I was a Founding AE at ExpoTV, taking the company from zero to $10M ARR. I spent six years in sales leadership at Salesforce and grew my territory from $1M to $25M at Outreach. I've been on every side of the table — founder, operator, first hire, and leader — which is why I can tell the difference between a motion problem, a message problem, and a market problem.

I work from current market patterns, not old playbooks. The 300+ conversations aren't background. They're the product. Every week I publish one pattern from those conversations — what's showing up in deals right now, not what worked in 2022.

In June 2026, I co-authored “Startup Founders Need a New Sales Playbook” in Harvard Business Review with Prof. Vincent Onyemah of Babson College, introducing the SPRINT framework — drawn from interviews with more than 250 founders worldwide.

I work with B2B SaaS founders at $500K–$10M+ ARR who are either trying to fix a stalled revenue motion or make their first sales hire without breaking what's working.

But none of this is how it started. Here's the real story ↓

How this started

The practice grew out of the worst year of my life.

At the end of April 2025, I was fired — seven months in, the shortest tenure of my career.

A first-time founder wanted sales to grow faster than it was going to grow, and that was that. I told myself I’d take the summer off, play golf, and figure out what I wanted to be when I grew up.

A month later, I was diagnosed with prostate cancer.

The summer I’d pictured was gone. I knew that if I didn’t do something to distract myself, I’d go crazy. So I made a public goal on LinkedIn: I’m going to meet 100 founders in 100 days.

People responded. Most of them had never sold before — technical founders, building good products, thrilled to talk to someone who’d run go-to-market. We’d talk, and they’d say, can we do this again? Then they’d refer me to someone else. Then they’d post about it. It was the purest form of networking I’ve ever done.

I didn’t share what I was going through at the time. I just needed a distraction. There was no plan for a business.

Somewhere in there, a founder asked if I was documenting any of this. I record every call, so I figured I could. I started turning what I was hearing into a newsletter. The more I published, the more founders came.

The story I could tell was different from most. Not what worked in 2021 when money was free — but what a manufacturing-tech founder in Munich told me this morning, what a prop-tech founder in Boston told me yesterday.

So people started hiring me. And once we got their motion down, they’d ask the same next question: do you know anyone I can hire? So I started building the largest network of founding account executives anywhere.

In August 2025, I had my prostate removed. Knock on wood, I’m cancer free.

I’ve now met with more than 300 founders in over 40 countries. What I learned from them became an article in Harvard Business Review, and it’s the foundation of everything I share here.

I named it 100 Founders after the goal that pulled me out of an uncertain time. I hear that same uncertainty in a lot of the founders I talk to now — and that’s exactly who I built this for.

The newsletter from the story

It started as notes from those calls. It still is.

100Founders is the newsletter I started writing when a founder asked whether I was documenting any of this. One pattern a week from the conversations I'm having now — not what worked in 2021. Every Saturday.

If you'd rather start with your own motion: the 12-question diagnostic names your primary constraint in five minutes. Free, no call attached.
