Gleap connecting customer messaging, feedback, automation, and AI agents in one workspace.
Trusted by 4,500+ companies
Customer.io is one-way. Gleap is the loop.
Customer.io sends. Users receive. When they reply or report a problem, Customer.io has no inbox, no AI, no agent. Gleap captures every reply, routes it with AI, and resolves 80% via Kai - same platform that sends your campaigns.
Gleap inbox capturing replies to campaigns that Customer.io can't handle.
Same event signal. Both directions.
Customer.io fires campaigns on events you instrument. Gleap fires campaigns on the same events - and also reads bug reports, support conversations, and feature requests to feed the AI agents. One signal, both directions.
Bidirectional event flow - campaigns out, support and bug signals in.
Email + push + in-app
Lifecycle, behavioural, triggered - full marketing automation included.
Token-based AI usage
Customer.io has no AI support agent. Kai resolves routine inbound with usage billed by actual tokens and selected model.
Bug reports → PRs
Kai Code captures replay + logs and starts plan mode. Customer.io has no equivalent.
Roadmap built-in
Kai PM ships a public roadmap and writes the release notes - Customer.io has none.

What you gain: Kai Code
Bugs in your campaign cohort become PRs.
A user triggered by your onboarding campaign hits a bug. In Customer.io, that's lost - there's no inbox. In Gleap, Kai Code captures session replay, logs, environment data, and starts a Kai Code run with the full context attached.
See Kai Code
A Kai Code bug report opening a Kai Code run from a campaign-triggered support conversation.
Kai PM clustering campaign-reply feature requests into a revenue-weighted roadmap.
What you gain: Kai PM
Feature requests from campaigns become roadmap items.
When users reply to your campaigns with feature requests, Customer.io has no place to put them. Kai PM captures, clusters, scores by revenue impact, and publishes to a public roadmap. The voters who replied get personalised release notes when you ship.

Switching from Customer.io
Does Customer.io have a support inbox?
No. Customer.io is one-way - campaigns out, replies bounce to your email. Gleap has a full multichannel inbox + AI agent that resolves 80% of conversations automatically.
Can one tool replace Customer.io and Intercom?
Yes - Gleap. Email + push + SMS + in-app campaigns (matching Customer.io's strengths) plus an AI support agent, bug reporting, public roadmap, and changelog (matching Intercom + more). One subscription.
What about Customer.io's segmentation and event triggers?
Gleap supports the same. Behaviour, attribute, event, schedule. Plus signals from AI agents - Kai knows the support history, Kai Code knows the bugs, Kai PM knows the feature requests. Richer segmentation than Customer.io can build alone.
Do you have an API and event ingestion?
Yes - full REST API, webhooks, MCP server. Server-side event ingestion identical in shape to Customer.io's. Migration is mostly remapping event names.
How long does migration take?
Most teams live in a day. Import contacts and campaign templates. SDK install is one line. Guided setup ~30 minutes.
Is Gleap SOC 2 certified?
Yes - SOC 2 Type 2 audited, GDPR compliant, EU/US data residency on Enterprise.
Send the campaign. Catch the reply. Close the loop.
