How Will Cannon built two SaaS companies doing $30M by copying what works

Executive overview

Most founders waste time trying to invent new markets. Will Cannon built two SaaS companies past $30M in combined sales by finding markets with proven product-market fit and adding a small, targeted twist.

The twist comes from one-star reviews — find what customers hate about the market leader, then build the version that fixes exactly that.

Copy proven markets, find the gap in the leader's reviews, acquire customers with one repeatable channel.

The four-step framework

• Find a market with existing product-market fit — don't try to create a new category
• Identify your unique angle: pricing alone is not enough; it must fix a real complaint
• Mine one- and two-star reviews of the top players to find the twist customers actually want
• Acquire customers profitably using one core channel — cold email, cold calling, SEO, or ads
• Execution is the hardest part; expect to fail 15–20 times before one works

How Uplead was built

• Ran a data-list agency for 10 years; vendor data was only 50–60% accurate
• No tool existed that could export a prospect list with real-time email and phone verification
• Built Uplead to solve their own internal problem — the need existed because they'd felt it daily
• Grew to $1M ARR entirely through cold email before adding other channels

The cold email that drove $1M ARR

• Subject line: "Hi [first name]" — reads like a personal message, not a blast
• Opener: "I was checking out your LinkedIn profile and thought this could be valuable to you"
• Value prop: "We built a tool like ZoomInfo but with real-time verification and we're affordable"
• CTA: "Are you open to trying it out at no cost?" — low-friction, hard to refuse
• Short, human, one clear ask — no hype, no long pitch

How Signaturely was built

• 2020: saw that document signing was moving entirely online
• DocuSign dominated but was complex; identified "too complicated" as the core complaint
• Built a simpler alternative explicitly targeting users who found DocuSign hard
• Reached 1.6M users primarily through SEO: free tools (online signature generator) and ranked contract templates
• Templates and tools funnelled users directly into the product

Three market opportunities Will would pursue today

1. Simple CRM — large, fragmented market; multiple billion-dollar players; room for a simpler entrant
2. Payroll software for small businesses — fragmented, proven demand; copy FreshBooks' SEO-templates playbook
3. Website analytics tool — near-infinite addressable market; differentiate by adding AI and LLM-mention tracking

Advice for early-stage founders

• Start with small goals, then raise them — momentum compounds
• Don't sweat daily obstacles; stay focused on the big picture
• Expect failure; two successes came after roughly 20 failed attempts
• The playbooks already exist — most people just don't study them
