It's really hard to put level 3 on a resume though. For example, I had a situation where we built a product from 0 to release in 2 weeks, got revenue and hundreds of buyers by the second month, without any funding. But just writing it that way doesn't make it clear whether it was luck, skill or the effort of colleagues.

You can give context, and what you did.

"After noticing the need for X, I proposed we build Y. As a team we build an initial prototype, and within two weeks we had revenue and hundreds of buyers."

Example from my resume:

"I created a new product from scratch for the company. I researched user needs, explored the solution space (http://...), and then built Telepresence (http://...), a local development environment for Kubernetes. As of Feb 2019 the project had grown to 1600+ GitHub stars and is now a CNCF Sandbox project."
