KARTPULL is building the network that helps shoppers unlock greater purchasing power, and helps retailers create more value from every store visit.
Retail promotions are built around a threshold: spend this much, unlock this benefit. The threshold exists because it works — it lifts basket size and moves inventory. But it assumes something that is no longer true: that every shopper arrives with enough purchasing power to reach it alone.
Most don't. They fall short by a margin small enough to be frustrating and large enough to matter. At that moment there are only three outcomes, and two of them destroy value: the shopper over-buys something unwanted, or abandons the offer entirely. Only the third — reaching the threshold with intent — creates the outcome the promotion was designed for.
The result is a structural inefficiency sitting inside almost every store: demand that exists, intent that is real, and no mechanism to combine it. Retailers price the discount into the campaign and then don't get the volume. Shoppers see the offer and can't reach it. Nobody is at fault. The infrastructure simply doesn't exist.
Over the last decade, consumer behaviour reorganised itself around groups. Products are discovered through communities and creators. Decisions are validated by reviews, comparisons and group chats. Online, entire commerce companies have been built on group buying — one of the world's largest was built almost entirely on the insight that people buy differently together than they do alone.
Every stage of the customer journey has been rebuilt around this behaviour except one. The transaction itself is still modelled on a single person acting independently — one shopper, one cart, one threshold.
Each era of commerce technology solved a distance. Collaborative commerce closes the one that remains — the distance between shoppers standing in the same store.
Collaborative commerce doesn't manufacture demand or discount deeper. It connects purchasing power that is already inside the store, at the same moment, chasing the same offer.
Rare in retail: the shopper gains access to value, the retailer gains basket size and redemption. No margin is transferred between them — the offer was already budgeted.
No POS integration, no pricing change, no new hardware. The layer sits on top of promotions retailers already run, which is why it can spread at software speed.
Each side makes the network more valuable to the other. Because matching happens inside a store in real time, the advantage is earned market by market — which is what makes it durable.
Threshold-based promotions are near-universal in physical retail. Wherever they exist, the same fragmented purchasing power exists — which makes expansion a question of density and sequencing, not reinvention.
The mechanic doesn't change from category to category — which is what makes this a network to grow rather than a product to rebuild.
We're building the layer that lets shoppers act together inside physical retail.
We started with the simplest honest version of that idea: two shoppers, one store, one offer neither could reach alone. Not because it's the whole vision, but because it's the part that can be proven — and a network this only earns the right to expand by working, repeatedly, in one store before the next.
So we're beginning in Bengaluru, with a measured pilot, published targets and the discipline to stop if the numbers don't hold. What we're building toward is larger: an intelligence layer for physical retail, where promotions are shaped by real demand, and purchasing power is something shoppers hold together rather than alone.
Commerce spent two decades getting faster. We think the next decade makes it collective.
Whether you're exploring retail collaborations, partnerships, strategic opportunities, or simply want to understand what we're building — we'd be glad to hear from you.
