Aptos Xponential, NYC Edition 2025: a week in the Builder House

In February 2025, the Aptos Foundation invited our founder, Vin Lim, to Xponential in New York. Xponential is a working program, not a conference. Vin spent it in the Builder House: a table, a laptop, mentorship from the engineers who build Aptos itself, and a room full of founders from across the ecosystem.

Vin founded Arteesan, a blockchain-backed art platform our team built, where every work carries an on-chain certificate of authenticity and its full history of ownership. Behind that sits more than a decade of software engineering and ten years as a Google Developer Expert working on the open web. Aptos runs on Move, a language designed to make digital ownership safe to represent on-chain, which is the exact problem Arteesan works on. The fit was direct.

What the Builder House is actually like

A conference is a stage and an audience. The Builder House is a different kind of room. Aptos Xponential brings builders from around the world to New York for a week and pairs them with grants, product and design support, and direct time with the engineers who build the chain. You bring a project that is already in progress and work on it in the open: short demos to the rest of the cohort, one-to-one office hours with Aptos Labs and Foundation engineers, and honest feedback from people who have shipped before. You leave with the project further along than when you arrived, or you wasted the week.

That format suits how we work. We would rather sit with an engineer who has hit the same wall than watch a keynote about it. Most of Vin's days there were spent at a laptop, not in a seat.

What Vin brought to it: provenance you can verify

The project Vin took into the room is the one our team has spent years on. Arteesan puts art on-chain so two questions have permanent answers: is the work authentic, and whose hands has it passed through. For most of the market those answers live on paper that gets lost or faked. On Arteesan they live on a ledger no single party can quietly rewrite, and the record travels with the piece instead of sitting in a drawer.

Aptos matters here because of Move. Move treats a digital asset as a resource that cannot be copied or accidentally destroyed, which is a stronger foundation for ownership than a general-purpose contract bent into shape after the fact. For provenance, and for tokenising a work or a share in it, that safety is the whole point. It is the same argument that runs through our wider digital-asset infrastructure work, and the same platform that went on to be the official digital partner of CIMB Artober 2025, Malaysia's largest art exhibition.

What we brought back

Two things stuck with us. First, the engineers building Aptos care about the same problem we do: making digital ownership safe to represent and move on-chain, which is exactly what art provenance needs. Second, a week of building next to other founders is worth more than a week of talks about building. Vin came home with Arteesan further along, a shorter list of open questions, and people on the Aptos side we still talk to.

We build the software; the invitation was a chance to build it better, close to the people who build the chain it runs on. That is the kind of week that shows up later in the product, not the press release.
