Full Stack Apps
Our team builds highly performant full stack apps for Web, iOS & Android.
From auction engines to HIPAA-compliant patient apps, we architect and ship production systems that hold up at scale.
Rock Solid Business Machines
Our web, native, and desktop apps process millions of dollars each year for our clients through excellent maintainability, consistency and resiliency.
Our Process
We like to start new engagements with our Technical Blueprinting phase. We listen, research, test, and consolidate our plan into an architecture document that guides the build.
Our development process is agile, transparent, and collaborative, managed through lightweight weekly touch points, tight feedback loops, and waves of iteration.
As your product rolls out, we’re standing by, fixing bugs, performance-tuning, and shipping new features in real time.
An Embedded Finance Experience
Stripe brought us in at the very beginning of its Stripe Apps initiative to build one of the first apps in the ecosystem and set the bar for user experience.
We partnered with Stripe and Xero to concept, design, and implement an app that would integrate Xero financial data directly into Stripe’s user dashboard.

HIPAA compliant patient onboarding
When we built Tend’s Patient Onboarding, we wanted to allow customers to access real-time insurance estimates.
Using React & Ruby on Rails, we built a modern and performant experience, using HIPAA compliant components all the way through to the database.
Read about TendWe’re friendly and transparent because the best relationships produce the most meaningful work.
Safety & Testing
Through typesafe programming and a careful approach to programatic testing, we build solid, reliable apps that are easy to maintain and iterate on for years to come.
Your voice has a rhythm
We designed the app and website to be visual representations of human emotions, utilizing color and a curated collection of video to reflect each feeling and meet users where they're at.
The app uses AI to detect emotion in a user's voice and, in turn, provides music to support them based on their needs in that moment.
By combining voice analysis technology with thoughtful design and curated musical content, Thea creates a space where emotional wellness feels accessible, intuitive, and deeply personal.

We know to trust simple things because they have mastered intricacy. They have met the world and stayed intact.
A bridge is trusted when it bears load repeatedly. Meeting force again and again, proving it can hold, bend, and not break.
Today, our team is worldwide, but we started in NYC, and we’re still mostly based in the US Eastern timezone.
