About Checkmate and Mate. 🛍 📲
Checkmate is a multichannel offers network loved by 100M shoppers and hundreds of leading brands. mate. is your AI growth teammate, the eCommerce data network that agentically turns customer intelligence into revenue.
mate finds it, Checkmate goes and gets it. Checkmate is the distribution network, with 100M+ shoppers and 12B+ live intent signals. mate is the AI layer built on top of it: it resolves anonymous visitors, spots the revenue a brand is missing, and builds and executes the campaigns to capture it.
mate runs six agents for brands:
Mate Intelligence: a customer dashboard and AI chatbot that surfaces the revenue a brand is missing.
Enrichment: identity resolution that reveals and resolves anonymous visitors.
Growth: AI-built, single-use offers delivered across our network and a brand's own channels, priced on performance, with no retainers and no lock-in.
Social Activation: enriches social handles into full shopper profiles.
LLM Visibility: tracks and grows how a brand shows up in AI search and assistants.
Code Leakage: finds leaked discount codes and replaces them with single-use ones.
The combination is rare: a consumer product shoppers love and an AI growth engine brands depend on.
We work with leading brands like Everlane, Brooklinen, and Malbon, and we're backed by Google Ventures, Mantis VS, Fuel Capital, and others.
