Why us
How we're different here
Built to survive Microsoft's release cadence
Outlook's add-in platform changes under your feet — new runtimes, deprecated APIs, shifting manifest formats. We build against the unified manifest where it's stable, pin what isn't, and maintain add-ins through platform updates so yours keeps working when Microsoft ships.
The unglamorous details, handled
Tenant consent flows, throttling, offline states, the web/desktop rendering differences nobody blogs about. This is the work that separates an add-in demo from an add-in your whole company uses daily.
FAQ
Common questions
Yes — validation, policy compliance, and the certification review loop, including resubmissions. We've been through it enough times to avoid the common rejections.
