Everything you need to know about WhileYouSlept.lol — the daily SaaS revenue tracker powered by TrustMRR.
WhileYouSlept.lol is a daily revenue tracker that shows how much money SaaS startups are making every day. It pulls verified MRR (Monthly Recurring Revenue) data from TrustMRR and highlights the latest revenue milestones, acquisitions, and growth numbers shared by founders on X (Twitter).
TrustMRR is a platform where SaaS founders verify their monthly recurring revenue by connecting their Stripe or payment processor. WhileYouSlept.lol uses TrustMRR as its data source, so all MRR figures shown on the site are verified — not self-reported.
Startups listed for sale on TrustMRR are marked with a "For Sale" badge on WhileYouSlept.lol. You can spot them in the feed and in the featured section at the top of the page. Click through to TrustMRR for details on asking price, verified revenue, and how to make an offer.
WhileYouSlept.lol ranks all startups by daily revenue (MRR divided by 30). The top earners appear first in the feed. Cards expand on hover to show monthly MRR, 30-day growth percentage, and verified status. You can also browse the full leaderboard on TrustMRR.com.
MRR stands for Monthly Recurring Revenue — the predictable income a SaaS business earns every month from subscriptions. It is the most common metric for valuing and comparing subscription-based software businesses. ARR (Annual Recurring Revenue) is MRR multiplied by 12.
Startup revenue data is synced from TrustMRR daily at midnight Eastern Time. Founder tweets are scanned hourly for the latest revenue milestones, acquisition announcements, and growth updates.
WhileYouSlept.lol is a discovery tool — it helps you find SaaS businesses for sale with verified revenue. Startups marked "For Sale" link directly to their TrustMRR profile where you can see the asking price, revenue history, and contact the founder to negotiate a deal.
Click "Advertise" on the homepage to get a featured card at the top of the page for $49/week. Your startup will be shown to hundreds of founders, indie hackers, and SaaS buyers who visit daily. Payment is handled securely through Stripe.
Unlike marketplaces like Acquire.com or MicroAcquire, WhileYouSlept.lol is not a marketplace — it is a real-time revenue feed. It combines verified MRR data from TrustMRR with live founder tweets to show what is actually happening in the SaaS world right now. Think of it as a daily scoreboard for SaaS founders.
The feed highlights three types of milestones: MRR/ARR updates (e.g. hitting $10K MRR), SaaS acquisitions and exits (companies sold for a specific amount), and monthly revenue reports shared by founders. Only tweets with real dollar amounts are included — goals, advice, and speculation are filtered out.
