Using our SaaS boilerplate

Authentication, billing, admin, and user management do not need to be built from scratch.

Senior Engineering

Production-grade quality

Built by an experienced SaaS developer with real product, architecture, and launch experience.

"The attention to detail, thoughtful approach, and creative inclination provided the most ideal outcome to jumpstart my SaaS product. In my capacity as a UX Lead at Apple I've worked with countless engineers - of which Kyle stands ahead of the pack. I hope to continue leveraging Gravity long into the future."

Case Study - Mogl

A custom SaaS product used by customers daily

Mogl.com helps brands and agencies take control of programmatic advertising, retail media, and data measurement. We built Mogl's SaaS application from the ground up using our SaaS boilerplate as a foundation.

That meant we could move fast on the things that matter: product workflows, UX, reporting, and differentiating features, while relying on proven building blocks for auth, billing, and admin.

The process: scope the product, ship and deploy the first release, then keep improving it. We have continued building new features for Mogl for over a year.

"Kyle was highly responsive and thoughtful in helping build our SaaS to fit our specific business needs, which made adoption and extension significantly easier. Gravity enabled us to ship a production-ready SaaS web app with confidence in both its technical and economic sustainability. Partners log in to our dashboard hub daily and have commented that it delivers the modern SaaS experience they expect."
