The Lifecycle Messaging Standard is open. No system holds it yet.

## What we build on Customer.io

2 projects from the LeanScale catalogue run on Customer.io, each with a typical timeline from our delivery record.

- **Email and nurture infrastructure** (Marketing Ops, Blueprint, Marketing automation): Templates, nurture programs and compliance your team can launch from. Typical timeline: 2–4 weeks.
