Michael, a Stanford Economist

I’m tired of fixing outdated advertising for marketplaces. I wish someone can have an ad engine that works right from the beginning.

Francisco, a Silicon Valley Engineer

Advertising isn’t as cool as it could be...

Yeah, let’s build that into an API maybe? The next generation of marketplace monetization tools!

Regina, a Vendor desperate to sell products!

Complex technology to simplify the advertising stress for vendors & retailers - love!

Francisco came from Chile to Stanford for an MBA. He took a marketplace design class with Michael and kept in touch for years after. Regina is a Gen-Z entrerpreneur / computer science student that started a DTC brand in school and ended up selling most of the products through retail and Facebook ads. Advertising was the signle most hard problem she faced during scaling her first business.

Through random chances of life and its events - the three met, first just virtually as it was in the midst of covid. Regina being a former small vendor with need for diverse advertising tools, Francisco an engineer that builds systems at scale, and Michael the brilliant economist with faith in simple product designs - decided to start a company together.

Empathy of Small Vendor, Baked in from Day One

Our dream of building a clean, effective, and simple to use ad alternative did not start with Topsort, but started within a college dorm room, as a small merchant’s struggle to learn direct-to-consumer paid ads, and also selling to B2B marketplaces as well as retailers.

What if ads just work without you losing a lot of hair and sleep over it? It’s the question we’ve strived to answer ever since.
