William Alan Callahan

Hello — I’m an entrepreneur that enjoys building relationships and businesses. I live in San Francisco and work in Silicon Valley, and grew up near Omaha, Nebraska, in the prairie of the United States.

Today, my highest professional priority is building aVenture, a research and investing platform that seeks to make investing in private startups easy.

My experience on the topic includes spending 5 years advising Morningstar on product development, 12 years building and managing another financial technology company, and more than 100 personal investments in venture capital and angel-backed startup companies.
