Why We Built Appsanic: The Origin Story of an Agentic Mobile App Builder

Every company's origin story is a little different from how it actually happened. Time smooths the rough edges. Decisions that were scary become obvious in retrospect. The weeks of doubt turn into a clean narrative.

This is our best attempt at the honest version. Why we started Appsanic, what we saw that made us think it was worth doing, and what we were wrong about.

The observation that started it

In early 2024, the first wave of AI coding tools had arrived. Cursor. Copilot. GitHub's built in AI review. They were real tools, and they made real engineers meaningfully more productive.

But we kept watching a specific thing happen. Non engineers would try these tools, get excited for an hour, and then quietly stop using them. Not because the tools were bad. Because the tools asked the user to be an engineer, and the user wasn't.

The contract of an AI coding assistant was: you tell me what code to write, I write it, you review the diff, you merge. Every step of that contract assumes the human can read code.

The non engineers we watched (founders with ideas, domain experts, designers, PMs, operators) could write prompts. They couldn't read diffs. The tools that were supposed to democratize software development were democratizing it only for people who were already almost there.

That gap was the observation that started Appsanic.

The bet we made

Three things had to be true for a product in that gap to work.

One: the AI had to be good enough to run autonomously. Not accept a diff and apply it. Read the codebase, plan the work, write files, run tests, fix bugs, open a pull request. Without human review of every step.

In 2024 this was not yet true for most tasks. By mid 2025 it was true for mobile app development specifically. The combination of React Native conventions, Expo's tooling, and tight feedback loops made mobile the first domain where agents could genuinely run the loop.

Two: the target domain had to be one where non engineers had a reason to build. Most domains aren't. Most people don't need to write their own CRM or their own Linux distribution. But mobile apps are different. Everyone has an app idea. Physiotherapists want tools for their patients. Indie makers want to launch their side project. PMs want to prove a prototype. The demand was real and massive.

Three: the economics had to work. An AI that writes a whole app uses a lot of tokens. A consumer willing to pay for that output was only going to exist if the value delivered was in the hundreds of dollars. Launching a real app to the App Store qualifies. Launching a side project that sits in a drawer does not.

When we looked at all three, they lined up. Not yesterday. Not next year. Right now.

The early months

The first version of Appsanic was ugly, narrow, and nervous.

The agent could only build a specific subset of React Native apps. If you asked for something it couldn't handle, it tried anyway and failed badly. We'd watch users hit the ceiling in their first session and churn.

Our response was to narrow further, not broaden. We picked mobile apps. We picked the mobile app patterns that actually work for the users we had. We said no to web apps, desktop apps, games, and every "can it also do X" request.

The narrowness was the thing that turned a demo into a product. Every week we widened a little. Every month we saw users who hadn't coded before launch apps to the App Store. The first time one of those apps got 100 real users, we knew the thing we thought might work was working.

What we got wrong

A short list.

We underestimated how much polish matters. The first version launched apps that ran. They didn't launch apps that felt great. Users who weren't engineers were more sensitive to polish, not less, because polish was a thing they couldn't fix themselves. We spent the back half of year one rebuilding the design instincts of the agent.

We overestimated how much users wanted flexibility. We released a lot of configuration options. Nobody used them. The users who wanted fine grained control went back to their existing dev tools. The users who came to us wanted opinionated defaults. We ripped out a lot of options and the product got better.

We didn't think hard enough about exporting code. We assumed most users wouldn't want to export. We were wrong. Even non engineer users wanted to know they could leave. The moment we added "export to your own GitHub" as a first class feature, trust went up and paid conversion went up with it. Ownership is a feature, not a convenience.

We thought the model was the product. The model matters, a lot. But the product is everything around the model: the planning layer, the execution environment, the connectors, the export flow, the preview on your phone, the editor, the collaboration. We built enough of those things early. Others we're still building.

What we got right

A shorter list.

Mobile specifically. The decision to not try to build a general AI builder was the single best decision. It let us go deep on the corners of mobile (Expo, EAS, App Store submission, iOS and Android differences) that a general tool can't cover.

Plan first, type second. Our agent pauses before writing anything. We held that line even when benchmarks rewarded speed. The pause is where the quality comes from.

Real code, real ownership. We decided early that Appsanic outputs a real codebase to a real GitHub repo the user owns. This is the opposite of the traditional no code platform model. We think it's the right model and the market is starting to agree.

Small team, high bar. We kept the team small and the hiring bar extremely high. Every engineer at Appsanic could be releasing production software on their own. This makes the team meetings productive and the product unusually coherent for its age.

What Appsanic is

Today, Appsanic is a mobile app builder with an agentic AI at its core. You describe what you want. The agent plans, builds, refines, and hands you a real codebase. The real codebase goes to your GitHub. You publish it to the App Store. You own it forever.

We have two models: Fast, for quick iterations and most work; Pro, for complex features where the agent should think longer and hold more of your codebase in context.

We have connectors with the tools real apps need: Supabase, Stripe, RevenueCat, Sentry, Resend, Expo's EAS for builds. We don't reinvent these. We wire them up for you correctly.

We serve founders, operators, domain experts, and increasingly professional engineers who use us for the parts of mobile they don't want to do by hand.

We are not done. We are still a small team. We are still learning. We have opinions and we are willing to be wrong about them.

What we believe

A short list.

Software as a craft is not going away. Taste, judgment, and product sense are scarcer than code. The bottleneck of building software is shifting from the writing to the thinking. We like this direction.

Ownership is a feature. Users who own their code trust the tool more. Trust translates to retention. Lock in as a business strategy works for a while and then stops working.

Small teams with high standards beat big teams with low standards. Our own team is living proof. So are most of our favorite companies.

AI will keep getting better. Anyone who builds a product assuming the models stop improving is going to be wrong. We build assuming they keep getting better and think about how to stay valuable when they do.

Mobile apps matter. The phone is where people actually are. Every year that passes, more of economic activity happens inside apps. The tools for building apps should reflect that.

What's next

The next year at Appsanic looks like this, roughly.

Fewer surprises in the deploy path. App Store submission, TestFlight, Play Store rollouts, OTA updates. All should be as automatic as the code writing is today. We're close, not there.

More understanding of large codebases. An agent that plans well at feature one should still plan well at feature forty, once the codebase has its own conventions and history. That's a harder problem. Much of our engineering work is here.

Better collaboration with humans. The best future isn't the agent writing code alone. It's the agent and a person working as a small team. We're building tools that let an engineer jump into the agent's work at any point, fork the approach, redirect, and stay in the loop without reengaging every five minutes.

The quiet ceiling. Every new model we release moves the line of what an engineer less builder can plausibly attempt. That ceiling has been rising steadily and we have no reason to think it stops rising.

The invitation

If you've read this far, you probably care about the kind of company we are as much as what we sell.

We are trying to be useful to the specific set of people who have an idea, want to launch it, and don't want to spend a year learning React Native to do it. We are trying to do this without hand waving, without lock in, and without cutting corners that will hurt users later.

We are not the only people trying this. We think we're doing it a little differently and a little better than most. Time will tell.

Come build something with us.
