What this is
Most SaaS products leak revenue somewhere between a signup and a habit. A user arrives, pokes around, and quietly never comes back. At low volume that looks like a rough edge. Once you start spending to grow, it becomes the most expensive problem you have.
Product Proof is about finding those leaks. Where activation stalls, where onboarding loses people, where retention breaks, and what each one costs you in growth now and in valuation later.
Who it’s for
Series A-B B2B SaaS founders who are close to their product and scaling acquisition. If you’re pouring money into growth and you’re not certain it’s landing in a product that holds, this is written for you.
What you’ll get
One core idea per issue, drawn from patterns across real SaaS products. No growth-hack listicles, no fundraising hype. Just a clear look at where products lose users and what it’s worth to fix it.
I diagnose. I don’t sell you a fix. The point is to show you the gap and what it costs, so your team can act on it on your terms.
Who I am
I’m Matt Smartt. 18+ years at the intersection of product experience and commercial outcomes, across early-stage SaaS and large enterprise. My job has always been the same: find where the product experience breaks down, and show exactly what it costs.
