Software built to order , engineered to pay for itself.
Web, mobile, and backend systems for B2B companies. We model the cost before we write a line of code — and if the math doesn't add up, we tell you before we start.
Web applications
We build web applications that sit at the core of the business — client portals, quoting tools, dispatch dashboards, internal systems. Not marketing sites. Typical stack: React/Next.js + Node.js + PostgreSQL.
Every build opens with a discovery sprint alongside your team — we map the process, design the architecture, and model the business case. If the numbers don't hold up afterwards, we say so before we start. No commitment to continue.
After delivery you own the code and the infrastructure. We don't rebuild auth, billing, and audit logging from scratch — Montei Core handles those, cutting delivery time by roughly 40%.

IPEX: Omni-channel Communications Platform
For IPEX, we delivered a large-scale omni-channel platform combining VoIP telephony with WhatsApp and Messenger integrations.
Read the case →Mobile applications
Mobile apps for companies where the phone runs the business — taxi fleets, field service, retail. Native (Swift / Kotlin) or cross-platform (Flutter, React Native), whichever fits your use case.
We specialise in products that have to work offline, handle real-time sync, and survive 24/7 operation. Example: a dispatcher plus driver app for 100+ vehicles at EasyGo.
We estimate cost after the discovery sprint — typically a few days with your team, fixed scope. Before you put money down, you know the timing and the budget.

EasyGo: Dispatcher Platform and Apps for 100+ Vehicles
For EasyGo, we built a full dispatcher portal, mobile apps, and automated billing for a taxi operation with 100+ drivers.
Read the case →Backend, APIs & integrations
Backends and integrations for where off-the-shelf ERP/CRM stops being enough. Microservices, event-driven systems, custom APIs. We connect your SAP/Salesforce/NetSuite to whatever you need on top.
We usually work directly with your CIO/CTO. We map the data flows, surface vendor lock-ins, and design a phased migration. If a step isn't genuinely needed, it comes out of the plan.
We don't roll out a finished ERP — every information system is a custom build on proven cores (Montei Core: auth, audit, billing). That's the ~40% delivery saving, with zero lock-in to us.

Uber: Taxi kiosk check-in at Václav Havel Airport Prague
For Uber, we delivered a kiosk check-in system at Prague Airport that lets passengers order taxis without the mobile app.
Read the case →AI integration into an existing product
You have a working product and want to add an AI feature that genuinely saves time. This is where we build it. Integrating ChatGPT, Claude, custom models, RAG over your company data, autonomous agents with a human handoff.
It's different from AI Discovery — there we ask "where does AI make sense"; here you already know the use case and we ship it. Typically 2–8 weeks, fixed scope, a measurable metric (time saved, accuracy, conversion).
We don't build chat widgets bolted onto a website. We build AI that lives inside the process — a copilot for predictions, candidate scoring, automated support triage.

Besegma: AI Copilot for Predictive Analytics
For Besegma, we implemented AI copilot capabilities and service integrations to expand their predictive analytics product.
Read the case →MVP & new product launch
MVP development for founders and corporate innovation teams. We take you from the first whiteboard sketch to your first paying customer.
We open with a discovery sprint (typically a few days with your team) — mapping the target audience, defining what the MVP must do, modelling the business case. Then a fixed build, typically 8–12 weeks, plus 4 weeks of optimisation against real data.
When you take a new product to market, we don't stop at release notes. We set up the landing page, basic analytics, the first acquisition campaigns. And when you decide to take it from here yourself, you have everything you need.
