8.5-Yr Plutio ($20K MRR, Unsold at $1.3M) vs. 0-Follower French Artisan App Khosmos ($22.5K MRR) & Karma
Why should solo founders never build a horizontal 'All-in-One Workspace' (projects + tasks + proposals + contracts + invoices + time tracking + AI)? Three verified Stripe and Google Search Console ledgers prove why vertical single-feature wedges crush bloated suites: 1) UK founder Leo Bassam spent 8.5 years (since Mar 2018) building the all-in-one freelancer suite Plutio (Super Work AI, plutio.com, 6,315 X followers, DR 69.0). Despite $1,501,612 all-time revenue, maintaining 7 horizontal modules trapped it in an 11-month plateau ($20,085 MRR?MRR (Monthly Recurring Revenue)Normalized monthly subscription revenue from active recurring plans—strictly excluding one-time setup fees, lifetime deals, or pass-through marketplace GMV., $17,124 30d revenue, $221,592 LTM across 909 subs, just 439 monthly visitors), leaving it unsold for 8 months at a $1,300,000 asking price (14 offers); 2) Meanwhile, 0-follower French startup Khosmos (khosmos.fr, founded Mar 2023) serves one narrow blue-collar niche — French construction artisans (artisans du bâtiment) — generating 1-minute mobile quotes, electronic invoices, and mandatory reduced-VAT certificates (attestations pour la TVA réduite) at 23.99 EUR/mo. With 187,269 monthly GSC impressions, Khosmos hit $247,239 LTM, $22,505 MRR (865 subs), and $25,920 in Oct 2026 — overtaking 8.5-year-old Plutio! 3) Similarly, 82-follower New Zealand micro-plugin Karma (karmabot.chat) does just one thing inside Slack/Teams — peer recognition micro-bonuses at $3/user/mo — earning $748,996 all-time and $298,762 LTM!
How did a 0-follower French mobile invoicing app for construction tradesmen overtake an 8.5-year-old, DR 69.0, 6,315-follower 'All-in-One AI Workspace' in both MRR and LTM revenue? Let's audit the three primary-source Stripe and Google Search Console ledgers:.
