Finally, software you can ship in weeks.

The Johmacos is a small software studio in Vienna. We build web apps, mobile apps and AI-powered products for founders and businesses: fast, fixed-price and built properly.

01.What we build

Software for whatever your business needs next.

From a first MVP to a full production system. We scope it honestly, build it fast and hand you something real.

01

Web applications

Customer portals, dashboards, booking systems, internal tools and full SaaS products. Responsive, fast and built to grow with you.

02

Mobile apps

iOS, Android and cross-platform apps published to the stores, from consumer apps with live audio and payments to lean business tools.

03

AI-powered products

Chat assistants, intelligent automation and AI features built into your product. Done properly, not bolted on as a gimmick.

04

E-commerce & payments

Online stores, subscriptions and payment flows with Stripe, set up to take money from day one.

05

Data & automation

Systems that watch markets, crunch numbers and act on real-time data. The engineering behind our own trading platforms.

06

MVPs for founders

An idea and a deadline? We take you from concept to a launchable product that investors and first users can actually touch.

02.Selected work

Products we've built and run ourselves.

Every product below is our own, built with the same process we use for clients. Running them ourselves means we know what it takes to keep software alive after launch.

03.Why The Johmacos

Fast, affordable and well made. AI is what lets us offer all three.

Traditional agencies make you pick two. We build with AI at the core of the process, so the trade-off mostly disappears.

Speed

Weeks, not months

AI handles the repetitive scaffolding, so our time goes into the decisions that shape your product. You see working software early and often.

Cost

No agency overhead

No account managers and no meetings about meetings. You pay for focused building time, which keeps quotes well below traditional agencies.

Quality

Proven in production

Everything runs on the same stack as our own live products, tested against real users and real data. AI speeds up the work; it never replaces testing.

04.How it works
Step 01

Discovery call

Tell us your idea. We give an honest read on scope, timeline and cost, with no obligation.

Step 02

Plan & fixed quote

The idea becomes a concrete plan of screens, features and data, with a fixed price.

Step 03

Build in the open

Working previews throughout, not a big reveal at the end. Feedback goes in while it's cheap.

Step 04

Launch & support

We deploy and hand over the code and accounts. You own everything, and we stay available afterwards.

05. Contact

Have an idea? Let's build it.

Tell us what you want to make. You'll get a reply within 24 hours with an honest view on scope and cost.
