Sept 30Define
The main day. Challenge conventional thinking, explore the rise of Commerce AI, and discover the products, customer stories, and engineering innovations driving the next era of commerce.
Oct 01Build
Opens with the people who actually built it, then you take over. Three tracks, small circles, real problems, no slides. Then Boston, on us, in the afternoon.
/Agenda
What we'll argue about
Not a trade show and not a booth floor. A room of operators, engineers and executives who are building this, arguing about where it goes.
- 01
Retail Media Was Just the Beginning.
The category is turning into commerce itself.
- 02
Ad Servers Are Dead.
What replaces the infrastructure the last decade was built on.
- 03
Everyone Is Becoming a Media Company.
Travel, finance, delivery, marketplaces. Same destination, completely different paths.
- 04
What Happens When Campaigns Build Themselves.
Live, on real workflows.
- 05
Sponsored Listings in a Searchless World.
If discovery moves to agents, what happens to the format everything was built on.
- 06
Behind the Build.
A realistic sense of what building this involves.
- 07
Working Sessions.
The three questions nobody has answered yet are better worked through together.
Who'sin the room
Retailers, marketplaces, delivery platforms, travel, fintech and publishers from around the world. Engineering and product leaders who have shipped this, executives deciding whether to, and agencies working out what a searchless ad world means for their clients.
Boston
The main event runs at a venue in Somerville. We will also host a reception inside one of Cambridge’s iconic natural history museums. Full travel details go out with your confirmation.

Greetings from Boston,
For those asking when we’d all be in the same room again: it’s happening! Topsort's new event is coming to our Hub in Somerville, Boston on Sept 29 – Oct 1, 2026and we are inside of an old chocolate factory (literally)!
Three days of commerce, retail media, and the people building both.
Expect fewer slides and more conversation. Product in the open, ideas that aren't finished yet, and a long table where merchants, advertisers, and engineers can finally compare notes.
To join:, and let us know you're coming.
P.S. Bring a question you haven't been able to answer. Somebody in the room probably has.
P.S. This is a cute photo of us playing at Standford last year!
