The Problem

Data Engineering is a Challenge

Users’ data is hidden behind walls built by service providers. Accessing this data directly is a complex, time-consuming process that requires custom code and workarounds.

Security is a Constantly Moving Target

Providers’ security requirements are only getting more stringent, creating additional hoops to jump through during reviews for security verifications and certifications.

Maintaining Integrations Is a Tax on Your Team

When you build your own integrations, you also have to maintain them. If a provider updates their API, it can introduce breaking changes that leave you scrambling for a fix.

The Solution

One Integration. Every Provider.

Integrate once and connect to every inbox, calendar, or address book in the world — in real-time and with no custom code required.

Security You Can Trust. Control When You Need It.

Get the control you need to ensure you access sensitive user data securely. Bring new products and features to market with complete assurance that your integration is fully compliant.

Outsource Maintenance to the Experts
