How Andrew Kamphey Turned Google Sheets into a $5K/Month Business

Turning Spreadsheet Skills into Income

Andrew didn’t set out to build a training empire. He was the in-house “Google Sheets guy” at an entertainment startup, writing Apps Script to automate reports. Colleagues joked about his weird talent. Little did he know, this would become the core of a six-figure business.

Finding a Focus and Testing Ideas

In 2018 Andrew tried multiple side hustles—an influencer newsletter that sold for $37K and a small SaaS app that never got traction. When the pandemic hit in 2020, his partner pointed out that his spreadsheet demos deserved their own home. Combined with the lackluster SaaS growth, the timing was perfect to pivot.

A Lean 24-Hour Launch

Rather than overthink, Andrew opened Loom and recorded eight unedited tutorials in one day. Four free videos proved the value; four paid ones sat behind a paywall on Gumroad. He built a simple Carrd site, added a Gumroad button, and started selling—no upfront hosting fees, no design agency.

Gaining Traction with Marketplaces

After $390 in month one, the real break came via AppSumo. A lifetime deal shot subscriber count from a dozen to over 1,000. These were power users—finance analysts, marketers and operations pros—who shared feedback that shaped new modules and templates.

Diversifying Revenue Streams

Today Better Sheets brings in about $5K per month across multiple platforms: template sales on Gumroad (12%), subscriptions and consulting on Stripe (22%), AppSumo lifetime deals (50%), Udemy courses (10%) and YouTube ad revenue (2%). Free add-ons serve as a lead magnet for upsells.

SEO Efforts and Next Moves

Andrew has published a formula database, blog posts and free tools to drive organic traffic. Conversions remain low because many visitors seek quick answers, not courses. His focus now is on tightening that feedback loop—testing content themes faster—and expanding consulting services to cover upcoming expenses.

Key Lessons from Better Sheets

Turning a routine skill into a paid product takes less polish than you’d think. A rapid, no-edit launch lets you validate demand. Marketplaces can be growth engines when product-market fit is nailed. And a multi-pronged revenue mix keeps the business stable.
