Push notifications, user analytics, and payment rails wired together in a single SDK drop. Built for technical co-founders who need to be in production before demo day.
Your current stack is 5 SDKs, 5 dashboards, 5 billing accounts, and brittle glue code that breaks every sprint. Here's what that looks like side by side.

“Replaced 4 SDKs in one afternoon. Shipped the feature I'd been putting off for three weeks.”

“Demo day in 11 days. LaunchSDK got payments and push live in a single Saturday session.”

“The comparison table sold me before I even hit the signup. 35 LOC vs 643? Easy call.”

“Analytics are real-time. I watched signups tick up during our ProductHunt launch like a video game.”

“Firebase had us in vendor jail. One weekend migration and we're free. Revenue actually went up.”

“Crash reporting included at zero config? That alone saved us a Sentry subscription.”
