As a software development company in Budapest, we design and build the custom software a business runs on: desktop and web applications, ERP and CRM systems. Each system is built on a clear architecture, scales with the data and the number of users, and is documented for further development.
Our experience runs deepest in the demanding cases: performance-sensitive calculations, offline-first software, AI features, native code, and high-throughput backends.
Desktop and web apps
Backends and APIs
Data and hosting
Cross-platform desktop apps
One application for Windows, macOS, and Linux.
It runs as native code, keeps its data locally with background sync, and has direct access to the file system, peripherals, and connected devices.
High-performance web apps
Products, customer portals, internal tools, and dashboards that stay responsive on large datasets and under concurrent load.
Where a product requires it, we add real-time updates, fine-grained access control, and WebAssembly for computation in the browser.
High-throughput backends and APIs
The APIs and services behind your applications, designed for high throughput, low latency, and integration with third-party systems.
Performance-critical services are written in Rust, and every endpoint is typed and documented (OpenAPI), so other teams can build on it.
Native code
Rust for performance-critical components: memory-safe, with predictable latency and a small memory footprint
Local-first
Data is stored on the device and synchronised in the background with conflict resolution, so the application also works offline
Role-based access control (RBAC)
Single sign-on (OIDC, SAML), record-level permissions, and audit logging
AI features
LLMs integrated into the product: retrieval, tool use, structured data extraction and automations
Integrations
Typed APIs (OpenAPI), signed webhooks, payments, and e-invoicing (NAV, Peppol)
Observability
Structured logs, metrics, and traces (OpenTelemetry), with alerting on errors and latency
Example of what we deliver.
An ERP for liquid cargo operations: inventory, ownership transfers, blending, and transport documents in one system, with role-based access and a full audit trail. The web and desktop applications share one Rust core, and the desktop application works offline and syncs when the connection returns.
96%of operations recorded on the day they happen, from a little over half
79%faster to close the month (from two weeks to three days)
We analyse how the business operates, including its exceptions, before writing code, and prepare the specification ourselves.
02The best modern tools available+
The language, the database, and the hosting follow from what the workload requires.
03No overengineering+
The simplest system that runs fast, covers every workflow, and scales.
04Reliability and performance+
Performance targets and failure handling are part of the architecture from the start, verified by profiling and automated tests.
05Less consulting, more action+
Whatever stage your product is at, we move it forward with working releases you can use and review.
06Direct communication+
You talk directly to the engineers writing the code, so questions are answered by the people who know the system.
07Production-ready+
Monitoring, backups, automated deployment, and documentation are part of the first release.
08Fair price, no surprises+
A fixed price for the agreed scope. Anything beyond it is quoted before we start.
A first release (MVP) built to the standard of a finished product.
New software is judged against the mature products people already use, so we build the first release as a complete product: every workflow in the agreed scope, together with the admin interface, access control, reports, notifications, and the infrastructure it runs on (automated deployment, backups, monitoring).
The engineers who build the release also agree its scope with you. Common parts start from components we have already tested, so most of the time goes into your workflows, built on an architecture that scales as the business grows.
After launch, you agree to a short written interview for a case study. We agree what gets published before the project starts.
EU companies with a VAT number pay exactly this amount (reverse charge).
Questions about this service
Do you build websites?+
Not as a rule. We focus on applications: business systems, portals, and desktop software. For a marketing website, a web agency is usually the better and less expensive choice.
Do I need a CTO or a technical brief?+
No. We work directly with founders and the people responsible for the business workflow, and prepare the technical specification ourselves.
Can you build under our own brand?+
Yes. Agencies and product companies bring us projects for their clients. We work in your repository, follow your process, and the delivery goes out under your name.
What is included in the MVP price?+
The agreed first release: UI/UX design, development, testing, deployment, and handover. Our reference price is €11,500 (€9,200 as a founding client). Scoping is free, and bugs reported within three months of launch are fixed at no charge.
Do you build mobile apps?+
Yes. We build responsive web applications for phones and tablets, and a native app where a project needs one.
