Plenty of people start. Build your name as the one who ships the last ten percent.

Starting is common because it is the enjoyable part, while the final stretch is where the work turns tedious and unglamorous. That is exactly why finishing is rare and therefore worth something. A reputation for completing things is unusually cheap to build and nearly impossible to fake.

Take one stalled thing all the way to done this month, boring final details included. Notice how few people around you actually manage that. Then let it be known you are the one who does, not by saying so but by it being true repeatedly.
