Built on an AI-native foundation — and priced so you're not paying for the same customer twice.
Legacy vendors have not kept up
10+ year old software
Legacy vendors are built on tech from 10+ years ago, and now bolting AI on top. It’s slow and expensive.
The all-in-one compromise
All-in-one has always meant one channel done well, and the rest treated as afterthoughts.
Rising costs
Legacy tech and clunky bolt-ons means expensive R&D that gets passed onto you.
We built email for the AI era
Email built on top of the Agentic Context Platform: every detail a customer shares, wherever they share it- a form, conversation, or a past purchase- becomes part of the same Unified Profile.


Customer Signals
A signal can be structured data - like what a subscriber views, purchases, or shares through an onsite form or popup. It can also be unstructured: anything they share about their shopping preferences in conversations.
