Historical review from 2026-10-29. Current price and availability are unconfirmed; check the original marketplace.
Supascribe is a verified, 18-month-old marketing SaaS targeting Substack newsletter creators, reporting $2,432.80/mo in revenue and $2,117/mo in profit — an 87% profit margin that signals a lean, largely automated operation. The $75,000 asking price implies a 2.95x annual profit multiple, which sits at the lower end of reasonable for a software business with strong margins. The platform verification (TrustMRR, score 88) adds meaningful credibility to the financials. The primary limitation is a thin business description, leaving important growth, customer, and channel details to be gathered directly from the seller.
The software scope — a suite of growth tools for a single newsletter platform — is reproducible by a solo technical founder using AI-assisted development and existing Substack APIs for roughly $2,500–$8,000 in out-of-pocket costs over 6 weeks. However, the acquisition price is primarily purchasing 18 months of traction, verified $2,117/mo in profit, and an established user base within a niche community. The rebuild case weakens significantly when accounting for customer acquisition, SEO/word-of-mouth positioning, and the time required to reach equivalent revenue. The missing customer count and retention data are the main confidence gap; if the seller can confirm a stable and diversified subscriber base with low churn, the buy case strengthens considerably. On balance, the verified profit at a sub-3x multiple tips the verdict to buy, with customer retention data being the critical diligence item.
Cash estimate includes the AI tools, APIs and infrastructure needed for a solo founder to recreate the software. Build time is informational and lightly weighted. The verdict is driven mainly by customers, users, verified earnings, retention, distribution, brand, data and operating history.
