Startup failed (early employee).

Did my own startup; growth was insufficient. Ran out of runway (7yrs of doing startups).

Looked around & got a position as a Product Manager in AdTech, since I didn't want to get back into a dev role, and wanted to move more into the prod/mktg side.

Since then moved into an accelerator working with early-stage startups on mktg/prod.

Life's been much better than I expected when I failed.
