William Alan Callahan

Hello — I'm an entrepreneur that enjoys building.

I have a background that includes finance and technology. I live in San Francisco and work in Silicon Valley, and grew up in a small town 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 safer with better data. If you want to get in contact with me, you can connect with me on Discord, X, or LinkedIn.
