Standard tools no longer fit what you do
You've been working for years with spreadsheets, Notion, Airtable or a combination of tools that were never really meant for what you're using them for. Everything is duct-tape. Every new hire needs to be onboarded into your creative workarounds. And as soon as you scale, it becomes clear these tools are blocking your growth.
Spreadsheets don't scale
Excel and Google Sheets work up to a point, after which they become fragile, slow and error-prone. Two people working simultaneously causes conflicts instantly.
Generic tools miss the mark
Notion, Airtable and other no-code tools promise flexibility but break on your specific logic, roles and reporting. You build workarounds on top of workarounds.
Hidden licenses and vendor lock-in
Traditional IT companies build on their own proprietary frameworks or closed platforms with hidden license fees. After delivery you find out you are legally locked in, paying for usage rights that were never explicitly mentioned in the sales conversation. This is effectively the market standard, but it absolutely does not have to be this way.
There comes a point where standard tools no longer cut it. You have five spreadsheets linked by references, a Notion workspace full of workarounds, and someone on your team spending three hours a day tracking data that should be running automatically. You need something custom, but every quote from a traditional IT firm is shocking. €80,000. €120,000. Eight-month timelines. Plus another €15,000 per year for maintenance. And you later find out they built the entire thing on their own proprietary framework that you can't escape from.
We build custom platforms completely differently. Our team consists of senior founders with combined experience building and scaling software companies with 40+ employees, supported by a full-stack developer with a background in cybersecurity and AI/ML. That means you work with experienced people directly, not junior consultants using your project as practice. We work with modern frameworks like Next.js, React, Astro and PostgreSQL. And we use AI smartly for high-volume work where it genuinely adds power, like content structuring, data migrations, test generation and documentation. Not for fundamental architecture decisions. Those stay with our team, because that is where the real value lies.
Here is what most IT companies will not tell you in the first meeting: they build on their own proprietary frameworks and closed platforms that you keep paying for through licenses or mandatory maintenance contracts. This is effectively the market standard. We at Managium absolutely do not work this way. Everything we deliver is transferable: complete source code, open technologies, database migrations and full documentation. Tomorrow you can switch to any other agency, in-house developer or internal team without anything breaking. We deliberately make ourselves redundant at delivery. We deliver custom platforms on average 30 to 50 percent cheaper than a traditional IT firm, and often three times faster. Not by compromising on quality, but because we work lean with a small, experienced team. No layer of junior consultants, no project managers, no account managers billing hours for progress updates. No handoff delays between departments. Just senior founders who have themselves built and scaled software companies to 40+ employees, plus a full-stack developer with a background in cybersecurity and AI/ML. We understand what an SMB CEO cares about because we have been one: speed, transparency, fixed price, and no hidden costs.
Mastone - Real estate portfolio platform with WWS points calculation
Context
Mastone manages a real estate portfolio and had to work with the new WWS points system. They used spreadsheets, could not share professional brochures with investors, and lacked oversight of their portfolio. They needed a full platform with an admin side and an investor portal, including complex calculations with more than 100 conditions.
Challenge
The WWS points calculation contains more than 100 conditions with specific weighting factors and exceptions. Manual calculation via spreadsheets was error-prone and time-consuming. They also wanted user management, role-based access, professional online brochures and a dedicated investor portal. A traditional IT firm quoted between €80,000 and €120,000 with a timeline of six to nine months.
Our approach
We built a custom platform with complete WWS calculation module, automatic brochure generator, admin environment and investor portal. Modern stack with Next.js, PostgreSQL and a custom authentication layer. AI was used for structuring and documenting the 100+ calculation rules, test generation and data validation. The team worked in sprints with weekly deliveries.
