The sale listing
Listed on TrustMRR on Oct 20, 2026 at $75,000[1], about 2.6 times MRR × 12 and 3.0 times the last 12 months’ revenue.Derived The listing shows 757 interested buyers and 7 offers[1].
Market
Other tools also sell growth features to Substack writers. We found no rival with verified revenue on the same basis, so revenue is not compared.
For buyers: the listing, checked
A small, high-margin tool tied to one platform, priced near two years of revenue.
The base matters here because revenue includes yearly plans: the ask is 1.7 times 30-day revenue × 12 but 2.6 times MRR × 12, and 1.3 times a year at November’s pace[1].Derived October was the best month on record at $3,113, and early November is running faster still.Derived

Supascribe shows how one person can earn from a platform’s missing features with a capped free tier and usage pricing, and how much that business depends on the platform staying as it is.
Why we scored it this way
Copy
- Build what a growing platform leaves out. Substack’s gaps are Supascribe’s product. P1
- Give away a capped free tier. 1,000 views and 100 subscribers, then pay. P2
- Charge for usage above each plan. $2 per 10,000 views or 100 subscribers. P2
- Lead with search. The only channel listed, and a domain rating of 65. P3
Avoid
- Ignoring platform risk. One Substack release could copy the core. §10
- Reading the writer count as customers. §02
- Judging a yearly-billed product by one month. §02

- Little history is visible. One archived TrustMRR page and no archived pricing page.Check: not public.
- October may be a renewal month. Yearly plans bought last October would renew now.Check: November and December revenue.
