Why custom?
Beyond the default ConvertKit integrations.
ConvertKit (now Kit) is built for creators, but creator businesses scale into needing real integrations. We build ConvertKit integrations that move data between courses, communities, and ecommerce.
What we build with ConvertKit

Course platform integration (Teachable, Thinkific, etc.)
Custom subscriber tagging from purchase events
Webhook-driven automation triggers
What you can expect
What a ConvertKit integration usually delivers.
Subscribers that stay in sync with your real systems
Sign-ups, purchases and cancellations flow into ConvertKit automatically from your site, store or app, so your lists reflect who your customers actually are rather than a stale manual export.
Tagging and sequences driven by real behaviour
Events from your platform, such as a purchase, a booking or a plan change, trigger the right ConvertKit tags and sequences, so automations respond to what people do instead of only when they signed up.
Revenue you can actually attribute
Sales and product data joined to ConvertKit activity, so you can see which sequences and broadcasts drive income rather than guessing from open rates alone.
A sync that does not quietly drift
Webhook-driven updates with retry handling keep ConvertKit and your systems aligned, so a single failed call does not leave a customer tagged wrong for weeks.
How we build
Production-grade.
Not Zapier in a trench coat.
Every ConvertKit integration we ship handles failure properly: idempotent jobs, retry logic, dead-letter queues for unrecoverable cases, and observability so you can see exactly where data is at any moment.
Tested
Real test suite, real edge cases. Not just "it worked once."
Observable
You see what is happening — events logged, errors surfaced.
Maintainable
Documented, version-controlled, handed over properly.
