About the show
Sumofied is the podcast where AppSumo founders meet agency owners. Host Drew Rattray scores every tool against the Agency Viability Score (AVS) rubric: white-label depth, multi-client management, reseller viability, integration flexibility, and roadmap confidence, so agency listeners know what's actually worth buying. Learn · Launch · Scale.
SheetXAI
David De Souza is the founder of SheetXAI, a Google Sheets and Excel AI add-on that automates spreadsheet workflows for non-technical users. Before SheetXAI, David ran three agencies — most recently a customer success consultancy for SaaS companies, plus organic GTM at StartupHelpr and a Facebook ads shop for local businesses going back to 2018. He built the first version of SheetXAI overnight in December 2024 after one too many midnight VLOOKUP sessions on a client SEO project. Connect with David at sheetxai.com.
Key quotes
"I would say, and in all honesty, I don't think it's probably the best app for white labeling. It's more an internal tool. Like it helps your company focus on the stuff that actually matters for your company rather than necessarily it being something you sell to people." — David Souza
