Shaun Clark Interview: How HighLevel’s Co-Founder Built Go HighLevel for Agencies

May 30, 2025•5 min read

I interviewed HighLevel co-founder and CEO Shaun Clark. HighLevel also featured me on its own show.

Here is what Shaun told me about building HighLevel for agencies only, the night five apps cost a roofer a lead, and why I run every client system on Go HighLevel.

The Night Five Apps Failed Me

At 11:42 p.m. a Colorado roofer called me, swearing the phone tree ate his $75-per-click Google lead.
Turns out lead #188 had been forwarded, zapped, tagged, abandoned somewhere between Calendly and the CRM-du-jour.

Five apps, one lost roof, zero excuses.

That was the moment I went looking for one platform that could do it all. It is the same problem Shaun Clark set out to solve.


How Shaun Clark Built HighLevel

Before HighLevel, Shaun ran an answering service for about 12 years and then built InvoiceSherpa, an accounts receivable automation tool. Selling software to small businesses one at a time was hard, and that pushed him toward agencies. In 2018, Shaun Clark, Varun Vairavan and Robin Alex founded HighLevel, an all in one, white label platform built for agencies. They bootstrapped it before taking minority growth investment in 2021 and 2024.

Today HighLevel says it supports more than 120,000 customers and over 1 million small businesses in 150+ countries. It ranked No. 426 on the 2024 Inc. 5000 and No. 516 on the 2025 list.


How a Roofing Crew Became a Case-Study Legend

I slammed HighLevel into that roofer’s duct taped stack:

  • Missed-call text-back = +38 % quote requests

  • Review automation = 97 new 5-star reviews in 30 days

  • Pipeline triggers = $1.3 M revenue lift in 60 days

In this episode, “Why Go HighLevel Said No to Everyone but Agencies,” Shaun and I talk about:

  • Why he built HighLevel

  • A community that polices itself and grew past 5,000 members

  • Being a second time SaaS founder

  • Why they stopped selling to lawyers and dentists and went all in on agencies

  • Shipping new features every week

  • Taking the risk, and what entrepreneurship asks of a marriage

  • Building an onboarding team so agencies stop getting burned

Beats, Bars, and a CRM

When Produced by Nef swapped Google Sheets for HighLevel, every Instagram DM paired to a beat-store funnel. He sold out two exclusive tracks in 48 hours, then cloned the snapshot for other producers at $297/mo.


Featured on HighLevel Spotlight Sessions

HighLevel invited me onto Spotlight Sessions, its own show on the official HighLevel YouTube channel, after I shared how Codie Sanchez’s Contrarian Thinking mastermind rewired my approach to scaling. The episode is “Mark Crandall On Taking Equity In Your Market.”

On that same platform, I mapped out the Testimonial Waterfall and automation sequence behind a $5.1M offer to buy a company I built, an offer I ended up walking away from. (Proof that owning your tech stack creates options you never saw coming.)

What a Go HighLevel Build Looks Like for a Client

Sarah Jones had wanted to get her business online for a long time and did not know how to start a landing page. We built two full landing pages and every automation in Go HighLevel, then recorded a walkthrough so she was comfortable running it herself. In her words:

"He did a great job and I'll definitely be using him again."
