Composer.AI: a $2.1M AI music app, listed for sale while one site shows MRR down 69%
Figures are source-labeled by the listing sites named in each citation. WorkAINow has not audited them. Data as of 2026-10-20.
The angle: Composer.AI (also sold as SongMaker.AI / Muxa AI) is the highest-MRR AI app in our data that we hadn't covered yet. It's also the clearest example of why you need a date on every revenue number. Two listing sites show figures 3.4× apart, and the seller changed the asking price seven times in five days.
The numbers, side by side
| Metric | whatsthe.app (data dated 2026-10-01) | TrustMRR (synced 2026-10-20) |
|---|---|---|
| MRR | $76,012 | $22,565 |
| Last 28/30 days revenue | $77,375 (28d) | $25,764 (30d) |
| Active subscriptions | 5,685 | 3,755 |
| Lifetime revenue | not shown | $2,128,186 |
| Asking price | $1,500,000 | $1,100,000 |
Sources: whatsthe.app/muxa-ai, trustmrr.com/startup/muxa-ai. The whatsthe.app page links to the same TrustMRR listing (whatsthe.app), so both pages describe one business.
TrustMRR also shows MRR down 69.0% and revenue down 67.6% over the last 30 days, with a 40% profit margin for that period (TrustMRR). The gap probably comes from timing: whatsthe.app's figure is dated 2026-10-01, and TrustMRR's falling 30-day numbers suggest a sharp drop after that. That's our reading, not something either site states.
What it sells
The listing describes it as an app to "create original AI songs" (TrustMRR). The in-app purchases listed on whatsthe.app mix a subscription with consumable packs (whatsthe.app):
- Subscription: "suno-Pro weekly" $6.99 and "suno-Pro Yearly" $69.99
- Song packs: 20 Songs $3.99, 60 Songs $6.99
- Credits: $4.99, $9.99, $19.99; "extends" $0.99 and $1.99; "SingerModel" $2.99
Two products carry "suno" in their names. Whether the app uses Suno's models, or has any agreement with Suno, is unknown. No source we have says.
The for-sale story
- TrustMRR records seven asking prices between 2026-09-11 and 2026-09-15: $1.1M → $1.5M → $1.3M → $1.35M → $1.0M → $1.35M → $1.1M (TrustMRR asking-price history).
- whatsthe.app still shows $1.5M with a listing date of 2026-09-11 (whatsthe.app).
- Estimate: at today's TrustMRR figures, $1.1M is about 4.1× annualized MRR (method: asking price ÷ (12 × $22,565)). Against the whatsthe.app MRR, $1.5M is about 1.6× (method: $1.5M ÷ (12 × $76,012)). whatsthe.app shows 1.6× itself (whatsthe.app).
Distribution: one warning sign
The App Store link on the TrustMRR listing (apps.apple.com/us/app/muxa-ai-music-songmaker/id6503041526) returned HTTP 404 when we checked on 2026-10-20. Apple's lookup API returned no result for that ID in the US, GB, DE or TR stores (TrustMRR; WorkAINow check). Why it's gone (removed, renamed, region change) is unknown. A missing store page would be enough on its own to explain a falling MRR.
What other founders can copy
- Pair a subscription with consumable packs. Song packs and credits let one-off users pay without subscribing (whatsthe.app). Over its life the app has taken in $2.1M (TrustMRR).
- Don't build on a name you don't own. Products named after a third-party model ("suno-Pro") are a platform and trademark risk. We can't tell if that played any part here, but it's an easy risk to avoid.
- If you sell, pick one price and keep it. Seven price changes in five days, and two sites showing different prices, makes buyers ask questions before they make offers.
- Put a date on every number. A buyer who reads whatsthe.app sees $76K MRR. One who reads TrustMRR today sees $22.6K.
Unknowns
- Why MRR fell, and why the App Store page returns 404
- Team, country, acquisition channels and ad spend (none listed by either source)
