We build complex, production-grade applications and systems that real businesses and real users depend on every day.
Marketplaces with identity verification, payments and payouts. Field operations systems used by teams on the ground. Multi-country platforms running in five markets and 21 languages. Not brochure apps, not templates.
We work with founders and operators from the planning stage onward: shaping the idea into something feasible, building it, launching it, and staying on afterwards for growth and continuous development.
Petadev LLC is based in New York, with our engineering team in Budapest.
We build custom applications for iOS and Android platforms, tailored to business and user needs.
Development of web apps, admin interfaces, and internal systems that support business processes.
Scalable, secure server-side solutions for complex systems.
Connecting existing systems, API development, building automations.
Maintenance and optimization of existing applications, development of new features.
Let's talk through your project!
Business planning and market entry
We don't start at development, and we don't end there either. Most apps don't fail because of the development itself, but because nobody thought through the business side, or nobody can find the finished product. We help you think through the concept, bring the product to market, and then stand by you afterwards too, measuring, optimizing, iterating until it truly starts working.
From idea to working model
With a launch strategy
ASO and targeted campaigns
Measurement and iteration
A marketplace where users rent out their belongings and take on casual jobs, paying each other with a saved card and getting paid into a pooled account.
Cost-sharing platform for pilots building flight hours, matching them with passengers to split the cost.
The web management interface of Trinity Guard: employers assign tasks, follow shifts in list and calendar views, and receive instant notifications.
A hiking app that guides users along the route of the adventures they buy, with playful tasks, in-app card payments and a language switcher.
You pay as the work lands, not upfront. Each milestone has a defined scope and a working deliverable, you always see what you're paying for before the next stage starts.
No account managers, no handoffs to a junior team you never met. Our team is five people, the ones who scope your project are the ones who write the code.
The platforms we built in 2019 are in daily use today, across five countries and 21 languages. We don't ship and walk away, we build systems that survive contact with real users.
Identity verification, split payments, payouts, dispute handling, multi-country data sync. These are where projects usually stall, and where we've already done the work.
Most software doesn't fail at development, it fails when nobody maintains it. We stay on for growth, measurement and continuous development, with Google Partner certification behind the market side.
CEO, Trinity Guard LLC
I recommend Petadev. A reliable, conscientious team that genuinely knows what they're doing. If you need an app that works and looks good, they're the ones to go with.
CEO, Ostva LLC
Petadev delivered the features and hit the milestones we agreed on. They deliver on time, and when they're behind, they put in the extra hours to catch up. What stands out most is how customer-centric they are.
CEO, MyCalamari SL
A talented, hard-working and honest team with solid project management and communication. We've been working together for years without a hitch.

Whether it's a web or mobile application, our goal is to create solutions that are stable, scalable, and sustainable in the long run.
Throughout the entire process, we work together with our clients, from planning through development all the way to market launch.
