XLSX
Find what's broken in your spreadsheet. Fix it in one click.
About
XLSX is a browser-based Excel auditor that shows you exactly what is broken in a spreadsheet and lets you fix it in one click. Open a workbook in your browser and XLSX scans it for broken formulas, error values, hidden sheets, and external links pointing at files you no longer control. Every issue is listed in a plain-English report grouped by sheet, so you can see the full picture before you change anything, then apply a one-click fix to the problems you actually want cleaned up. Privacy is central to the design: your file is never uploaded. The audit runs in your browser, so the workbook never leaves your machine. Scanning is free. Pro-style one-click fixes are a $9 one-time purchase, not a subscription. Built in Boston, MA by founder George Gilmer, founded 2026.

Our Elite price is $100 which is a lot to ask for in the App Store... but in the context of the user and what they're spending for their hobby — if you think about hunters spending thousands if not tens of thousands of dollars a year — and sometimes the deals you can get on these partners can make up the value of the app in a single purchase.
Brand Partnerships Can Justify a $100 Subscription When Discount Value Exceeds the Price
onX's Elite tier at $100/year bundles partner discounts from outdoor brands like First Light. For passionate hobbyists whose total annual spend on the hobby dwarfs the subscription cost, a single partner discount can recoup the price entirely. Contextualizing price against total hobby spend — not against other apps — eliminates sticker shock.
with Batistan which is the co-founder of Dram Magic we knew that it would secure 10K MMR because he had like this impact and with 10K MMR you can actually now spread with other creators you can actually do some ads
Give A Power-User YouTube Creator Equity To Lock In Distribution From Day One
Loick brings a YouTube creator on as equity co-founder to collapse the two biggest early risks — product and distribution — into one person. The creator guarantees baseline MRR (Drop Magic locked in ~$10K from Batistan alone), surfaces product feedback as a power user, and ships free iteration on scripts, funnels, and pricing until the unit economics are proven enough to replicate with paid creators.
There's a play for whatever you're stuck on.
