Founder Testimonials

What founders say about working with David.

A small number of engagements, taken seriously. Here's what a few people David has worked with have to say.

Shafer's input saved us time, kept us from continuing to spread the upside too wide, and helped us focus for early execution.

Founding Board Member

From the Founders

Real engagements. Real outcomes.

David doesn't tell you what you want to hear. He tells you what his experience says you need to hear — and then he helps you figure out what to do about it. That combination is rare.

Brett F.,

CEO, Early-Stage Tech Venture

We came in thinking we had a capital and resource problem. David helped us see it was actually a focus problem. That reframe changed everything about how we built the next six months.

Tim R.,

Co-founder, Broadcast Innovation

The Discovery Sprint was the most productive 30 days we'd had as a company. We left with a roadmap we actually believed in — and the confidence to execute against it.

Oscar J.,

Founder, EdTech Company
