Measuring productivity in software development is notoriously hard, but the demos I saw them give when the team of three people had been working together for three months showed more work then I would ever expect from a team of that size over that amount of time.
They already had their own custom agent harness and digital twin imitations of Jira and Slack and Okta and a bunch of other custom tooling.
It looked to me like way more than a 2x or 4x thing.
Opus can one-shot a simple Jira clone in under five minutes. I haven’t seen any of their work, but this “digital twin” story sounds like a marketing play.
I agree that productivity is very subjective too, in my experience a team of three developers with a solid plan could build a lot in three months even before AI.
The thing they're building here is specifically a clone of Jira that duplicates the official Jura API well enough that they can use it for integration testing without being held to Jira rate limits.
They do that by running the official client libraries against their implementation to make sure the functionality is all covered.
