Where it sits in the data

Cassandra's $10K a month is higher than 66% of the 6,604 projects with founder-reported monthly revenue in our dataset; the median across them is $2K. Snapshot: 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?

In my view, demand would come from marketing teams that need evidence for channel and investment decisions. The buyer is the team responsible for measurement and budget allocation, and distribution would require product-led content, educational material, integrations, and direct sales work.

The difficult parts are data connections, incrementality measurement, forecast reliability, and support for different marketing environments. Regulation, enterprise procurement, data handling, implementation load, and competition would also require serious work.

Verdict: Needs real work.

One thing to take from it

The strongest lesson is to make an expensive analytical decision clearer with a focused workflow: measure past channel impact, test current impact, report results, and model investment decisions.
