Circa
Hackathon concept to App Store launch in 17 days.
Circa turns context, interests, and intention into a considered date plan with real stops, pacing, walkability, and a quiet backup. Designed for two people who already want to meet and need the evening to feel deliberate, not generic.
The idea seeded at the OpenAI event and the GenSpark hackathon. The final build sprint, from concept lock to App Store, ran seventeen days, solo. No team, no partner. One person accountable for the brand, the product, the build, and the App Store cut.

The problem
After the match, the hard part is not finding another profile. It is turning mutual interest into a plan that feels natural, specific, and low-pressure.
Most people fall back to generic recommendations, endless back-and-forth, or one-place dates with no real arc.
The product
Circa builds a complete evening: a concept, a sequence of real stops, timing, walking notes, a map, and a quiet backup if the night needs to pivot.
It is designed for two people who already want to meet and need the evening to feel considered.
AI as the planning engine
AI is not the product's personality layer. It is the planning engine. Circa uses context, interests, vibe, constraints, and location intent to shape a route that feels coherent.
The AI earns its place by reducing planning friction, not by pretending to know the relationship.
“Applied AI is strongest when it disappears into a specific human workflow. The value is not an AI wrapper. It is the shipped product around it.”
The build
The constraint was speed without making the product feel disposable. The first version had to look considered, explain itself clearly, and survive the App Store.
The result is a focused iPhone app, a dedicated landing page, support and policy pages, and a complete App Store presence, shipped together.
Hackathon to App Store in 17 days
Circa went from hackathon concept to App Store availability in 17 days.
That timeline is the point: narrow the workflow, design the experience, ship the product, and make it usable outside the demo.
