About CartAI

Checkout is the last mile of every commerce experience. We built the infrastructure for it.

CartAI lets banks, loyalty programs, gifting platforms and AI applications buy from merchants across the web on behalf of their customers, inside their own product, with the merchant still the merchant of record. The team has done the last mile twice before.

CartAI is Manil's third commerce infrastructure company. He co-founded Lash Delivery, which turned Texas alcohol law into the first rules engine usable by delivery apps. H-E-B acquired it in 2017.

He then co-founded Delivery Solutions, the omnichannel enablement platform behind same day delivery, click and collect, shipping and returns for leading US retailers. UPS acquired it in 2022.

Both companies solved the last mile of a transaction that everyone else treated as someone else's problem. CartAI does the same for checkout.
