Founded in 2021 and headquartered in San Francisco, Topsort is a technology company specializing in AI-driven, auction-based advertising infrastructure for retailers and marketplaces. The company offers a platform that enables businesses to quickly launch, scale, and optimize their own retail media networks without relying on third-party cookies or invasive user tracking. Topsort operates globally, with additional offices in Boston, São Paulo, and Santiago, supporting clients across more than 40 countries.

As digital advertising shifts away from third-party cookies, retailers and marketplaces face challenges in monetizing their platforms while respecting user privacy. Traditional ad tech solutions often require extensive resources and technical expertise, making them inaccessible to many businesses. Topsort addresses this by providing a plug-and-play, AI-powered advertising infrastructure that enables companies to implement effective, privacy-compliant retail media solutions.

Joining Topsort offers the opportunity to work at the forefront of privacy-centric advertising technology, contributing to the democratization of tools previously exclusive to tech giants. The company fosters a collaborative, global work environment, emphasizing innovation, customer-centricity, and a commitment to ethical advertising practices. Employees are empowered to make significant impacts in a rapidly evolving industry.
