Your users are asking for an app. We build it without distracting your core team.
We ship companion apps — mobile extensions built for your users' on-the-go moments, not a clone of your web product. A dedicated mobile team for less than a single in-house engineer.

Sound familiar?
You know you need a mobile app. Here's why you haven't built one yet.
Build native mobile app (iOS + Android)
The backlog black hole.
Your users have been requesting a mobile app for over a year. It's sitting in your roadmap marked "Planned" — right where it was 18 months ago. Every sprint, web takes priority.
The $500k math doesn't work.
Senior mobile dev, designer, QA, PM — an in-house team runs $300-500k/year before benefits and recruiting fees. Plus 6 months of ramp before the first build ships.
The core-product distraction.
Mobile isn't just a build — it's another product to maintain forever. Every feature you ship on web needs porting. It divides attention away from the SaaS that actually pays the bills.
Here's the thing
A companion app isn't a mobile clone of your SaaS.
Your users don't need your entire admin panel in their pocket. They need the three workflows that matter when they're not at a desk — and they need them to feel native. That's what we build.
Standard mobile app
Companion app

After launch
Your dedicated mobile team. One 
slack message away
We install the AppStarter AI bot on your workspace. Report a bug, request a feature, or just ask a question — your team keeps using Slack. We handle everything else.
Customers keep asking for CSV export on reports — let's get it into next sprint's scope.
When your team discusses new features in Slack, our AI captures the conversation, extracts mobile requirements, and structures them into actionable tickets — automatically.

Results that speak for themselves
“AppStarter didn't just build us an app — they understood our business model, our users, and our growth stage. The companion app has been a game-changer for retention.”
“We went from zero mobile presence to live on both stores in 5 weeks. Our engineering team didn't lose a single sprint. That's exactly what we needed.”
“The AI Slack integration changed everything. Our product discussions automatically become mobile tickets. It feels like having an extra PM who never sleeps.”

Revenue impact
How much revenue is mobile already costing you?
Mobile cuts SaaS churn. Even a conservative 5% reduction is worth six figures for most SaaS. Try yours below.
