I'm a technical founder living in San Francisco. I am good at what I do, but I hate, hate, hate self-promoting. Am I doomed, or am I still able to build cred in my field?
You wouldn't be asking this question if you weren't conscious of losing out to more "extroverted" brands / personas.
Without knowing the field, the business, or the details, any advice I (or others) might give may miss the mark.
You are who you are. So concentrate on changing something else.
Assuming you offer a great service or product, then your problem isn't satisfying customers; it's making the right first impression and getting them in the door.
First impressions derive from such things as (1) brand name / domain, (2) graphic design, (3) written content. Obviously that's no complete list. But maybe you can identify one of those for making improvements.
