Topsort is moving through the retail media landscape with the kind of precision you usually only see in deep-space physics or championship-level chess, and the latest verified funding rounds make it clear that this team is not here for a cameo. Co-Founder & CEO Regina Ye, Co-Founder & CTO Francisco Larrain, and Co-Founder & Chief Scientist Michael Ostrovsky built a company that feels less like a startup and more like a global monetization backbone retailers have been waiting on for a decade. Upload Ventures led the $20M Series A, Pear Ventures and Quiet Capital came back with the kind of conviction that only comes from seeing the code up close, and strategic investors Moloco and RX Ventures added the weight that turns momentum into market gravity. When a company secures $28.5M in disclosed funding and an estimated $38M to $43M total with a $150M valuation, you are not watching hype, you are watching a system that works.
What makes Topsort electric is how the origin story snaps into place. Regina Ye learned the chaos of digital advertising while building ZIRUI, discovering firsthand how platforms turn sellers into spectators. Francisco Larrain engineered his way from Chile to a Groupon acquisition after building Zappedy, then stewarded 100+ engineers across multiple continents. Michael Ostrovsky brought auction theory that Silicon Valley platforms quietly lean on, backed by 6,400+ academic citations and years of advising major tech companies. Three founders with three different forms of firepower, and suddenly retailers everywhere get ad infrastructure that does not bleed data, does not cling to cookies, and does not require an army of analysts just to buy a sponsored listing.
You can measure Topsort’s reach by geography or by results, and either way the numbers refuse to stay quiet. Retailers across 40+ countries run on this platform, from Poshmark and DoorDash to Just Eat Takeaway, Coles, Magalu, Falabella, Farmatodo, LG Electronics, Liverpool, Weee!, Chiper, Atida, Breuninger, Ambev, Petco, HEB, Nana, OBI and more. Case studies read like performance poetry. Poshmark sellers hit a 43% sales lift and 3.8x ROAS. Concha y Toro clocked a 10.3x ROAS. La Rebaja surged 137% in ad revenue in just 2 months. Some retailers saw 60% revenue growth in 1 month after activating Topsort’s new AI model. When a company grows nearly 10x YoY and scales from ~63 employees to 121 across 6 continents, the signal becomes hard to ignore.
What makes the future even more interesting is the product ambition. In 2025, Topsort unveiled Toppie, Top Optimizer, and In-Store Journey, stitching together online and offline intelligence in a way that gives retailers both clarity and control. The acquisition of UK-based Phuzion Media extends that vision into physical stores, while partnerships with Skai and GroupBy widen access for advertisers chasing global reach. In a market sprinting toward $174.9B in 2025 and $196.7B in 2026, Topsort is not just scaling, it is shaping the path retailers follow next.
