Preston Junger

Founder, Founders Help Line

Twenty-five years building and scaling revenue functions, from pre-revenue through $700M. I have sat in the CEO, COO and CRO chairs, and I have been the first person on the ground in a new market more than once.

I started Founders Help Line because founders kept calling me with the same problem and nobody was answering the phone. That is still the job.

WHO YOU ACTUALLY GET

A short list of people, and you will know which one is yours.

I run the first conversation on every engagement and I stay on it. If someone here fits the work better, you meet them before anything is signed. That is why there are six names on this page instead of forty.

What we do

Go-to-market and revenue

ICP and positioning, pipeline architecture, qualification standards, outbound, enablement and certification. The motion itself, built so it survives the person who built it.

Capital and the exit

Narrative, model and data room rebuilt to survive diligence. Running the raise. Preparing a business for a process two quarters before it starts.

People and leadership

Founder and executive coaching, board dynamics, executive hiring, and turning a group of good individual performers into a team that compounds.
