Systems & identity integration

Enterprise Integrations

We connect your purchased platform to the tools you already run on — SSO, data warehouses, internal APIs — so it fits into your stack instead of sitting beside it.

Overview

A great product in isolation still creates friction if it doesn't talk to the rest of your stack. Enterprise Integrations wires your purchase into SSO, internal APIs, data warehouses, and whatever else your operations depend on, so it becomes part of the system rather than another silo.

Who this is for

  • Teams whose new platform needs to talk to SSO, warehouses, or internal APIs
  • Enterprises with a defined set of systems that must stay in sync
  • Buyers who don't want another data silo added to their stack

Who this isn't for

  • Teams without a clear list of systems to integrate yet (start with Map phase)
  • One-off manual data exports done rarely
  • New feature requests unrelated to system connectivity (see Custom Development)

Our approach

01

Map

Inventory the systems your new platform needs to talk to, and how data should flow between them.

02

Build connectors

Develop and test the specific integrations — SSO, webhooks, ETL pipelines, or custom APIs.

03

Validate

Run integration tests against real data flows before anything touches production.

04

Monitor

Set up logging and alerting so integration failures are caught immediately, not weeks later.

FAQ

Do you work with legacy or on-premise systems?

Yes, our team has experience bridging modern platforms with legacy on-premise systems via secure gateways.

Who maintains the integrations after delivery?

You own the code, but ongoing maintenance retainers are available if you'd rather we keep monitoring it.

Do you work with legacy or on-premise systems?

Yes — bridging modern platforms with legacy on-premise systems via secure gateways is common work for our integrations team.

Who maintains the integrations after delivery?

You own the code; ongoing maintenance retainers are available if you'd rather we keep monitoring it.

What happens if an upstream system changes its API?

Monitoring and alerting are built in specifically to catch upstream breakage fast, and retainer clients get priority fixes.

Can you integrate with internally built, undocumented systems?

Yes, though timelines extend slightly to account for reverse-engineering undocumented internal APIs.
