Why I Replaced My Company List With a Signal Map

When I began looking seriously at the Bay Area technology and AI ecosystem, I did the obvious thing and made a company list. It became useless almost immediately.

A list could tell me that a company existed and whether it had an open role. It could not tell me what was changing around the company, how quickly it was growing, who had funded it, which teams were being built, or whether its current needs matched anything I could contribute.

I was applying into a shape I could not see.

So I built the SF Tech Signal Map: a living research database that draws together companies, products, funding, growth, hiring activity, relevant roles, events, and key people. Scheduled AI research agents keep those signals refreshed on a recurring basis, so the system keeps gathering rather than leaving me with a spreadsheet that began aging the day I made it.

The part that matters most is what it does with that information. It compares each company’s current position with my goals, background, and present strengths. It helps distinguish between a company I may be able to approach now with something useful to say and one that belongs in a longer-term relationship-building path.

That changes the outreach itself. Instead of sending another general message about my career transition, I can understand what a company is working through, identify where my background may connect, and approach someone with a question tied to an active area of their work.

The Signal Map is not a market report. It is a decision tool for my own transition. It helps me decide where to move, where to learn, who to follow, and where I may have something relevant to offer now.
