Pilot Light Product
A small, deliberately scoped product kept running with low investment so a team retains the capability to ship in a category without committing to a full launch.
Why it matters
Pilot Light products preserve optionality — institutional knowledge, distribution, and infrastructure — at a cost that is easy to defend.
Example
A company maintains a single useful tool with one named owner and a quarterly check-in, ready to scale if the market signal turns on.
