Custom Software Development Services

SemBricks is a Dutch software development company that builds custom software around the way your business works. Off-the-shelf software forces you to adapt to someone else's process; custom software does the opposite. We design, build and run web applications, mobile and desktop apps, SaaS platforms, integrations, data pipelines and trading systems, from the first idea to software that runs in production for years.

Custom Software We Build

Applications. Custom web applications such as portals and business systems, mobile apps for iOS and Android, desktop applications and browser extensions.

Platforms and products. SaaS platforms, multi-tenant platforms and white-label software, and a fast start with an MVP or proof of concept.

Integrations and automation. Custom API development, API integration services, webhook integrations and business process automation that removes manual work between systems.

Data and insight. Data pipelines, data processing, reporting dashboards and real-time dashboards.

Tools for your team. Internal tools and business tooling that replace spreadsheets and copy-paste work.

Renewing what you have. Legacy software modernization and system migrations without stopping the business.

Trading and blockchain. Algorithmic trading software, trading bots, backtesting platforms and expert advisors, plus blockchain and web3 development.

When Custom Software Makes Sense

Custom software is not always the answer, and we will tell you when it is not. It pays off when:

• your processes are what sets you apart, and a standard package would force you to work like everyone else;
• your team works around the current software with spreadsheets, double data entry or manual checks;
• the systems you rely on do not talk to each other;
• a package's licence costs grow with every user while you only use a fraction of it;
• you are building a product of your own, such as a SaaS platform or a customer portal.

Often the best answer is a combination: keep the packages that work and build the missing piece or the integration between them. A build vs buy evaluation helps you decide with real numbers.

How We Work

1. Understand the work. We start with the people who will use the software, not only with a list of requirements.
2. Design. Screens, data model, integrations and architecture, captured in a design you review before development starts.
3. Short iterations. Working software in small steps, so you see progress and can steer early.
4. Launch. Data migration, training and a careful go-live, often next to the old way of working until everything checks out.
5. Operation and evolution. Hosting, monitoring, updates and new features, if you want us to.

Technology

We choose technology for what the software has to do: Rust where performance and reliability are critical, C# for business systems, TypeScript and Next.js for fast web front ends, and PHP where it fits the existing landscape. See all technologies we work with.

What You Can Count On

• Your code: ownership of the source code is set out in the contract, and it can be fully yours, including documentation and tests.
• Confidentiality: we sign an NDA on request before you share details.
• A Dutch company: clear agreements under Dutch law, and a team you can reach.
