Case Study: OttoInvites builds a kids party invitation app in 60 hours with Datarockets

OttoInvites launches a kids party invitation app in 60 hours with Datarockets

The customer, OttoInvites, was an internal project created by datarockets to solve two parallel challenges. The first was a methodological need for a real-world product to develop and test their new AI development harness. The second was a personal problem faced by their founder, who needed a dedicated digital invitation platform to simplify the chaos of planning children's birthday parties.

datarockets built the OttoInvites application using their AI-first development process, which relied on context engineering and strict guardrails to enable a single engineer to work autonomously. The solution included a fully-featured SaaS product with multi-language support, real-time dashboards, and comprehensive testing. The vendor, datarockets, successfully launched the app in two weeks with 133 commits, proving their AI harness methodology and creating a blueprint for future Agentic Engineering projects.
