Product
We’re a product engineering studio for ambitious teams
Custom platforms, native apps, and backends that absorb growth, from engineers who own the work end to end.
You’ve outgrown the platform that got you here. Leaving it feels riskier than staying.
Why Rare Days
1
We design and engineer it together.
Designers and engineers are in the room from day one, prototyping what can actually be built. The expensive calls get made while they’re still cheap.
2
We sort the hard parts first.
Permissions, audit trails, and load get settled in week one, not the week before launch. Nothing ships until the tests say it can.
3
We learned the fundamentals before AI.
Anyone can get a demo running. We build for month six, when real users and real permissions show up.
4
We build it, we run it.
We stay on after launch, refining as your product and your team grow. Our pod or our engineers inside your team, your call.
Platform Rebuilds & Migration
We move you off the platform you’ve outgrown and onto one you own, with web and native apps built on your own data model. Every user, record, and year of history comes with you. You get a platform that grows on your roadmap, not someone else’s.
Platform Migration
Web Applications
Native iOS and Android Apps
Community & Membership Platforms
“I love that I don’t have to be the smartest person in the room on the calls, because they’ve got really talented engineers and designers who add value and bring life to the vision.”
Jasmine Hadjis
CEO, IBE
Backend Architecture & APIs
We make the architecture calls early and test them against ten times today’s numbers, not just launch day. Data models, APIs, and access patterns get built to last. You get a backend nobody has to rewrite two years from now.

Security & Access Control
“Three years later, every card, video, and script a parent opens still passes through the same architecture and code.”
Aditya Jayaraman
Head of Engineering, Good Inside
End-to-End Engineering
Our engineers join your standups, sprints, and codebase, and own complete features front to back. We fill the gaps in your team, or bring an inherited vendor build up to your standard. You get depth fast, without slowing your roadmap.
Full-stack Product Engineering
End-to-end Feature Ownership
Vendor Codebase Takeovers
Embedded Engineering Teams
“Rare Days has exceptionally high standards for engineering and AI implementation. The turn around we had to release this product far exceeded our expectations. They helped level up our internal engineering team, and owned core parts of this product that accelerated us enormously.”
