Your tools should adapt to your business. Not the other way around .





















Tools built around your processes.
Custom CRMs
Your pipeline, your rules.
Your sales cycle stages, the data you need to see, automated actions at the right time. Your team opens one tool in the morning — everything is there.
Real-time dashboards
Drive by data, not by gut feeling.
One dashboard per role. The founder sees revenue and pipeline. Ops sees overdue tasks. Marketing sees cost per lead. Updated in real time, zero CSV exports.
Admin panels & portals
Centralize everything in one place.
Team management, order tracking, client portal, partner portal, billing back-office. One interface instead of 5 SaaS tools that don't talk to each other.
Integrations & workflows
Your tools, connected.
Stripe, accounting, emailing, business APIs. A qualified lead triggers a quote. A received payment updates the client tracker. Your team no longer has to play translator.
We built it for ourselves first.
Coddy — escape games in 9 countries. Behind the fully automated flow: booking management, real-time game tracking, multi-country admin, automatic invoicing. Not a single spreadsheet in the loop.
At Numinam, we build the same tools for companies that want to move beyond patchwork solutions.

Custom-built vs SaaS vs spreadsheets
| Numinam (custom-built) | SaaS (HubSpot, Pipedrive...) | Spreadsheets | |
|---|---|---|---|
| Process fit | Built around your processes | You adapt your processes to the tool | No structure |
| 3-year cost | Upfront investment, low recurring | 18K-72K€ (500-2,000€/month x 36) | Free... until the mistake that costs you dearly |
| Scalability | Modules added as you need them | Limited to the vendor's roadmap | Breaks when the team grows |
| Consolidated data | Unified dashboard, real-time | Siloed by tool | Scattered across 15 files |
| Security & GDPR | Secure architecture, EU servers | Depends on the vendor (often US) | A shared link is all it takes to break everything |
| Ownership | 100% yours, documented code | Tenant — you rent access | Yours, but fragile |

The price depends on the number of modules and the complexity of integrations.
Frequently asked questions about internal tools at Numinam
What types of internal tools does Numinam build?
Numinam builds custom CRMs, real-time dashboards, admin panels, client or partner portals, team management tools, and invoicing systems. Each tool is designed around the company's specific processes — not the other way around. The common thread: replacing spreadsheets and generic SaaS with a tool that fits exactly how your team works.
Why build a custom tool instead of using a SaaS like HubSpot or Pipedrive?
A generic SaaS works fine at first. But when your processes become specific — a particular sales pipeline, complex invoicing logic, business workflows the tool doesn't support — you end up paying for features you don't use while hacking workarounds for what's missing. A custom tool built by Numinam does only what you need, adapts as you evolve, and often costs less than a SaaS over 3 years (a €1,500/month subscription is €54,000 over 3 years).
Is it risky to build a custom internal tool?
The main risk with internal tools is building too much, too fast, without validation. That's why Numinam works in modules: we deliver a first module in 6-8 weeks, your team uses it, we collect feedback, then we build the next one. Each module works on its own. If you stop after the first one, you still have a working tool. Risk is managed at every step.
How long does it take Numinam to deliver an internal tool?
The first module is delivered in 6 to 8 weeks. A multi-module platform takes 10 to 14 weeks with progressive deployment. Complex projects (multi-entity architecture, data migration, deep integrations) span 14 to 20 weeks. At every stage, you have a usable tool — we don't make you wait 6 months before showing anything.
How much does a custom internal tool cost at Numinam?
Numinam offers three tiers: Starter Tool (€15,000 to €25,000) for a first module that replaces your spreadsheets, Growth Platform (€25,000 to €40,000) for a multi-module platform with dashboards and integrations, and Enterprise Suite (€40,000 and up) for a complete infrastructure that replaces your SaaS stack. Pricing depends on the number of modules, integration complexity, and data volume — not the number of meetings.
Will the internal tool replace members of my team?
No. The goal isn't to eliminate roles — it's to free your team from repetitive tasks so they can focus on high-value work. A salesperson who no longer spends 2 hours a day entering data into a spreadsheet is a salesperson with 2 more hours to sell. The tool doesn't replace people — it amplifies their impact.
Does the Numinam tool work with our existing software?
Yes. The tool is designed to integrate with your current stack: Stripe, accounting software, email services, project management tools, business APIs. Data flows automatically between systems, with no copy-pasting. If you use a tool that has an API (and most do), we can connect it.
Who owns the tool built by Numinam?
You do. 100% of the code belongs to you. No annual license, no vendor lock-in, no exit fees. The code is documented and maintainable — if you ever want to evolve it with a different team, you can. You own your tools. Period.
What happens after Numinam delivers the tool?
Numinam includes 3 months of support and maintenance after delivery (in the Growth Platform and Enterprise Suite tiers). Beyond that, you can subscribe to a maintenance and evolution retainer, or manage it internally — the code is yours. We don't create dependency. If you come back, it's because you want to, not because you're stuck.
We're a small team of fewer than 10 people — is it worth it?
Small teams often gain the most. When you're 5 or 8 people, every hour counts. A tool that saves 10 hours per week for a team of 8 is the equivalent of a part-time hire recovered — without recruiting. And Numinam's Starter Tool (from €15,000) is sized for exactly this type of team.
Why not build the tool ourselves in-house?
You can. But it means hiring a developer (€50,000/year minimum), managing the project (3-6 months before a first usable result), and maintaining the tool long-term. Numinam delivers a first module in 6-8 weeks, with design, development, integrations, and training included. The question isn't "can we do it in-house" — it's "is that the best use of our time and money."
How does Numinam protect data in internal tools?
Secure authentication, role-based permissions (each user only sees what they need to), encryption of sensitive data, traceable audit logs, GDPR-compliant EU server hosting, and automatic backups. Security is in the architecture from day one — not a patch added at the end.
How do you measure the ROI of a Numinam internal tool?
We measure 3 things: hours saved per week (how much manual work eliminated), errors removed (duplicate entries, lost data, missed follow-ups), and business impact (better lead tracking, faster invoicing, data-driven decisions). The math is concrete: 10 people × 10 hours saved/week × €35/hour = €18,200 saved per year. ROI is measured in months, not years.
10 people x 10 manual hours x 35€/h = 18,200€/year wasted.
And that's without counting data entry errors, leads slipping through the cracks, and employee turnover from people fed up with copy-pasting.
