No More Hassle With Tabs

About
The browser tab bar was never designed to hold dozens of permanent utility tabs. Yet most workflows end up with tabs for AI chat, RSS, weather, to-dos, color pickers, and more. Individually they seem harmless. Together they fragment focus and create constant tab overload.
TabCmdr replaces them with a single command palette.

B2B SaaS you can consistently say 90% gross retention — people look for much higher rates. And CSS you look at, 70 is a really good first-year annual retention rate, so then mathematically you shouldn't take on that much debt because you don't have that much cash flow guarantee.
CSS retention 70% vs SaaS 90% → cap leverage at 2-3x EBITDA
Crowley sets the M&A-grade retention benchmark for consumer subscription: 70% first-year gross retention is considered strong, materially below the 90%+ floor for B2B SaaS. That gap is why he caps recommended debt leverage at 2-3x EBITDA for CSS deals vs 4-5x for SaaS. Don't pitch acquirers against SaaS comps — position honestly inside CSS norms.
We went big with a big budget on paid acquisition and it was basically impossible to make the economics work out. We were seeing ROAS as low as 10% — economically it was just setting money on fire.
Paid UA push hit 10% ROAS — economically setting money on fire
In 2019 Lose It! tried to break free of organic-only growth with a serious paid push. Predicted 10-day ROAS curves came in at ~10% of LTV. The deeper lesson: competitors who make paid work (Noom, MyFitnessPal at 2x the price) priced around paid CAC from day one. Lose It! priced around an organic base — paid couldn't retrofit.
There's a play for whatever you're stuck on.
