ChurnLens for SaaS Acquirers answers one question: is this subscription revenue real? — not "what the seller says" real, but "will it still be here in 12 months" real. Send a raw subscription CSV and get a complete buyer-side risk report — logo churn, revenue churn, HHI concentration, annual renewal cliff analysis, and a 0–100 Revenue Quality Score — in 2 business days, not days. Built specifically for SaaS buyers, not sellers.
ChurnLens replaces days of manual spreadsheet due diligence with a single CSV upload. It computes logo churn, revenue churn, HHI concentration, annual renewal cliff risk, and a 0-100 Revenue Quality Score — benchmarked against 14 SaaS verticals. Built for micro-acquirers, search funds, and PE analysts evaluating SaaS acquisition targets.

A SaaS business can show flat MRR while its real retention is collapsing. ChurnLens surfaces these signals before you buy, so you price the deal on true revenue quality.
ChurnLens analyzes five dimensions: revenue concentration, logo retention, annual-plan churn risk, inactive paid accounts, and MRR decline patterns. Each is weighted into a single 0-100 revenue-quality score benchmarked against comparable SaaS businesses. The score tells an acquirer whether reported MRR is durable or propped up by customers who are one renewal away from leaving, all before the deal closes.
Purchase price is usually a multiple of recurring revenue, so overstated retention directly inflates what you pay. A business with 20% hidden annual-plan churn is worth far less than its MRR implies. Buyers who skip churn diligence discover the decay only after closing, when it is too late to renegotiate. ChurnLens gives that visibility during the evaluation window instead.
Watch for revenue concentrated in a handful of accounts, a widening gap between signups and active users, annual contracts that never renew, and MRR that grows only through discounting. Each pattern signals fragile revenue. ChurnLens automatically flags these red flags from uploaded revenue data and ranks them by how much they threaten the durability of the recurring revenue base.
