## 2. What the holding does

Maximilius Holding bundles a vertically integrated set of vastgoed (real estate) activities. The holding does not sell to end-customers under its own name — that's the role of the operational subsidiaries — but functions as the strategic parent: it owns the property portfolio, sets sustainability strategy, allocates capital, and coordinates between the operating companies.

Core capabilities under the holding umbrella:

1. **Vastgoedontwikkeling** — sourcing, structuring and developing real estate projects (woningen, bedrijfspanden, transformaties)
2. **Renovatie** — partial and full renovations of existing properties
3. **Verduurzaming** — energy retrofits, label upgrades, isolation, HVAC modernisation, solar
4. **Aannemerij** — general contracting (via subsidiary Maxiko) for own and third-party projects
5. **Keukenproductie** — custom kitchen design, fabrication and installation (via WWS Keukens)
6. **Energielabel-certificering** — issuing energy performance certificates as certified EPA advisors (via Labelmax)
7. **Proptech** — software tools for property valuation, value-jump calculations and exit simulations (via Vastgoedcalculator)
8. **Portefeuillebeheer** — managing the holding's own real estate portfolio plus advisory work for external investors

## 7. Philosophy

Maximilius Holding is positioned as the antithesis of the private-equity-backed vastgoedfonds. Key tenets:

- **One owner, no exit clock** — long horizon, decisions made for the next decade rather than the next reporting cycle
- **Vertical integration as moat** — owning the chain from advisory (Labelmax) → calculation (Vastgoedcalculator) → development (Maximilius) → execution (Maxiko) → finishing (WWS) eliminates margin leakage and information loss between handovers
- **Sustainability as business model, not marketing** — Labelmax exists as a profit centre on its own merit, not as a green-washing badge
- **Operating profit > vanity revenue** — the holding optimises for retained, compounding capital, not topline growth at any cost
- **Discrete professionalism** — Dutch merchant-family register: serious, understated, results visible in the portfolio rather than the press releases

## 8. Technology and infrastructure

The holding operates several first-party software platforms:

- **Maximilius Portaal** (mijn.maximilius.com): unified portal for clients, partners, investors and tenants — built on Next.js + Supabase, with rol-based access (klant, partner, belegger, huurder, admin)
- **Vastgoedcalculator**: customer-facing valuation tool
- **Maxbouw / MaxBo.nl**: internal project management system replacing third-party software
- **Partner programme infrastructure**: Subdomain-per-partner whitelabel hosting (`<partner>.maximilius.com`) for makelaars en EPA-adviseurs
- **TeamLeader Focus**: CRM and quotation system
- **Yuki**: financial administration

Tech stack: Next.js 16, React 19, TypeScript, Supabase (PostgreSQL + Auth + Storage + Edge Functions), Cloudflare DNS, Netlify hosting.
