Mobile App Development
in Los Angeles
LA Is Home
ClearSummit was born in Los Angeles in 2014. We've grown from a small team to a boutique agency with engineers across the Americas—but LA remains our headquarters. Our operations lead is here, our roots are here, and we understand what it means to build products in this market.
We've shipped apps for Belkin (right here in Playa Vista), built e-commerce platforms for enterprise retailers, and helped LA-based startups raise significant funding with products we architected. Whether you're in Santa Monica, Downtown, or the Valley, we're local when you need us to be.
ClearSummit is not cookie-cutter—they tailored their approach according to my project while keeping in line with initial expectations around budget, scope, and deadline. They do what they say they're going to do.
Apps We've Built
From LA startups to global enterprises

Why LA Teams Choose Us
LA's tech scene demands quality. We deliver.
Years Building Apps
Local Presence
Test Coverage
ClearSummit creates elegant solutions to challenges we threw at them with a minimal learning curve. They have a rare talent of understanding what they're building and what user context it needs to function with.
How We Work
Validate First
We start with Product Liftoff™—a 4-week process that validates your idea, creates interactive prototypes, and produces a development roadmap that actually works. 75% of startups fail because they build the wrong thing. We make sure you don't.
Architecture That Scales
Our architects design systems before developers start coding. We've built platforms handling thousands of concurrent users—and we've rescued apps that crumbled under their first traffic spike. You get technical architecture docs, API specs, and a clear roadmap.
Ship Every Two Weeks
2-week sprints with working demos. You see progress, test features, and steer the product. Full transparency: access to our project management tools, Slack channels, and the engineers building your product.
Launch and Beyond
App Store submission, production deployment, post-launch monitoring—we handle all of it. But launch is day one, not the finish line. We stick around for feature iterations, scaling challenges, and whatever comes next.
iOS, Android, or Both?
The right choice depends on your product, timeline, and users—not on our preferences.
For most LA startups, React Native lets us ship faster with a single codebase while maintaining native performance. For hardware-intensive products like Phyn, we architect custom native bridges. For apps requiring specific platform features, we build native Swift or Kotlin.
We recommend what's best for your product, not what's easiest for us.
Our Stack
Technologies We Master
We choose tools that give you leverage, not tools that are trendy.

Is This Right for You?
We're a good fit if:
You're an LA startup that's raised funding and needs to ship a quality product fast. You're an enterprise launching a new digital product and can't afford junior dev mistakes. You want a local team that understands Silicon Beach.
We're probably not a good fit if:
You're looking for the cheapest option. You want to micromanage every technical decision. You need a team of 50 developers next week.
