Founder at Crossbar TechnologiesMaker

I’ve spent over 25 years in adtech, building and selling adtech businesses. Crossbar is what I wish existed for indie builders: a slim bar you add to your site with one line of code. It shows other builders’ web apps to your visitors, and your web app shows up on their sites in return. No ad budget, no card, no tracking cookies. I built it because ads have priced out the people shipping the most interesting things.

    I’ve spent 25 years building and selling adtech businesses, and I built Crossbar because ads have priced out indie builders. Add one script tag and a slim bar appears on your site, showing other builders’ apps and some paid headlines. In return, your app shows up across their sites. No ad budget, no tracking cookies, and your visitors can close it anytime. I’m here all day and would love blunt feedback. How do you currently get your side projects in front of people?
