Why custom?
Beyond the default Slack integrations.
Slack is where teams already live. We build Slack integrations that surface the right signals in the right channels — new orders, support escalations, system alerts — and let your team act on them without context-switching to other tools.

How we build
Production-grade.
Not Zapier in a trench coat.
Every Slack 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.

FAQ
Common questions about Slack integration.
Can Slack integrate with HubSpot or Salesforce?
Yes — both with first-party apps and custom integrations. We build the custom version when you need specific channel routing, custom message formatting, or two-way actions the default apps do not support.
Do you build custom Slack apps?
Yes — internal Slack apps for your team are a common engagement. Slash commands, modal forms, message actions, and event subscriptions, all wired into your existing systems.
