Private beta · Composable customer layer

Your customer intelligence layer.
Plugs into everything.

Kernel isn't another platform to migrate to. It's the intelligence layer on top of the tools you already run, including Segment, HubSpot, Shopify, Stripe and Klaviyo. One customer view, AI you can act on, and value back into every platform you plug in.

Works standalone · Gets smarter with every source you plug in · Own your data

Built on top of the platforms you already run

ShopifySegmentStripeKlaviyoResendHubSpotWebflow

Your stack already owns the data. Kernel makes it work together.

Shopify has the buyers. Stripe has the payers. Klaviyo has the openers. Segment has the pipes. Kernel is the layer that unifies them, adds intelligence, and pushes sharper audiences back into every one of them. Every tool gets better at its own job.

  • One unified profile, merged from every source you connect
  • Complements your existing CDP, ESP and CRM. Never replaces it
  • AI agents that answer, segment and draft campaigns for you
  • Two-way sync: push audiences back to Klaviyo, Meta, Google Ads
  • Own your data: export as CSV or query via API any time

The layer your stack never had.

Unified profiles

Deduped, merged customer records across every business, source and channel.

Multi-workspace

Run every business you own from one login. Data stays isolated, or roll it up.

Event stream

Every action a customer takes, timestamped and queryable. No sampling.

Real-time segments

Save a query, get a live audience. Pipe it into any campaign tool.

API-first

Every read and write is a REST call. Webhooks in, webhooks out.

Portable by default

One click CSV export. No lock-in, no migration fees, ever.

Intelligence layer

The moat isn't storage. It's what you do with it.

Segment moves the data. HubSpot runs the workflows. Kernel is the brain that connects them: ask questions in plain English, get answers, segments and campaigns grounded in your actual customer data, then push them back into the tools that act.

Ask, don't query

Ask which customers are likely to churn in 14 days. Get an answer, a segment and a draft winback email.

Auto-segments

Kernel finds behavioural cohorts you didn't think to build. Ship them straight to your ESP.

One-click activation

Push any segment into Klaviyo, Mailchimp, Meta or Google Ads audiences. No CSV shuffle.

Not instead of. On top of.

Kernel doesn't replace your tools. It makes them better: cleaner data out, sharper audiences in, and more value flowing through every platform it plugs into.
