With the Series B round, my startup began actively managing tech debt.  When an engineer finds something major we create a Jira issue, user story style.  The head of product (a technical person) prioritizes a blend of product features vs tech debt for each sprint.  Usually that&#x27;s 10-25% tech debt, which includes mostly non-critical but beneficial refactoring as you described.  It&#x27;s worked well for us.
