Where it sits in the data

Sublo's $1.6K in the last 30 days is higher than 81% of the 5,602 projects with payment-verified revenue in our dataset; the median across them is $150. Within the “Entertainment” category (351 projects) it is higher than 83% (category median $207). Snapshot: 2026-09-02 to 2026-09-30. The dataset only covers founders who chose to publish their numbers, so it leans toward businesses that work; use it for scale, not as an average.

Currency

All figures are in US dollars as published. A rough yuan or euro conversion is not applied here because prices, taxes and acquisition costs differ by country.

Could you build something like this?

My view: the demand is clear enough at the product level. The buyers are language learners, film fans and teachers who assign streaming exercises. The product gives each group a visible way to work with two subtitle tracks during ordinary viewing.

My view: distribution would need to come from browser extension discovery, search around language learning and streaming, and partnerships with teachers or viewing communities. The hard parts include keeping translations synchronized, supporting changing streaming interfaces, handling browser and service updates, managing support and dealing with the rules around modifying streamed video.

Verdict: Needs real work.

One thing to take from it

Sublo presents one focused job with a free entry point and a simple paid plan. The useful lesson is to make the core result visible immediately: two subtitle tracks, real-time translation and no account required.
