+# 💼 TaLibStandard — Commercial & Enterprise
+
+TaLibStandard is **open source** (GPL-3.0) for individual and research use.  
+For commercial applications, we offer flexible licensing and support options.
+
+---
+
+## 🎯 Who Is This For?
+
+| Use Case | License |
+|---|---|
+| Personal projects, research, academic use | ✅ GPL-3.0 (free) |
+| Startup / bootstrapped product | ✅ GPL-3.0 (free, GPL terms apply) |
+| Commercial SaaS or proprietary software | 💼 Commercial license required |
+| Trading firm / hedge fund / prop shop | 🏢 Enterprise license |
+| Cloud API or hosted service | ☁️ Enterprise / OEM license |
+
+> **GPL-3.0 means:** If you distribute a product that includes TaLibStandard, your product must also be open source under GPL-3.0. If you need to keep your code proprietary, a commercial license removes this requirement.
+
+---
+
+## 📦 Licensing Tiers
+
+### 🥉 Developer License — €299 / year
+> For independent developers and small teams (≤ 3 developers)
+
+- Commercial use in proprietary applications
+- Email support (48h response)
+- Access to all future versions in the license year
+- Named-developer license (non-transferable)
+
+---
+
+### 🥈 Professional License — €999 / year
+> For companies and teams of up to 10 developers
+
+- Everything in Developer
+- Priority email support (24h response)
+- Integration guidance session (1h/year)
+- Up to 10 developer seats
+- Use in multiple commercial projects
+
+---
+
+### 🥇 Enterprise License — from €3,999 / year
+> For hedge funds, prop trading firms, fintech companies, and larger teams
+
+- Everything in Professional
+- Unlimited developer seats
+- Dedicated support channel (Slack / Teams)
+- SLA: critical bugs fixed within 5 business days
+- Architecture review session (2h/year)
+- Custom indicator development (available as add-on)
+- OEM redistribution rights available
+
+---
+
+### ☁️ Cloud API (coming soon)
+> Hosted TaLibStandard as a service — no .NET required
+
+- REST + gRPC endpoints for all 200+ indicators
+- Pay-per-call pricing model
+- SDKs for Python, JavaScript, Rust (planned)
+- Ideal for: non-.NET stacks, serverless, backtesting pipelines
+
+---
+
+## 🤝 Custom Development
+
+Need an indicator that doesn't exist yet? Custom backtesting integration? Real-time SignalR feed?
+
+We offer **paid consulting** for:
+- Custom indicator development
+- Integration with trading platforms (TradingView, MT4/MT5, Interactive Brokers)
+- Performance optimization for high-frequency workloads
+- Quant workshop training (remote or on-site)
+
+---
+
+## 📩 How to Purchase or Inquire
+
+1. **Open an issue** with the label `[commercial]` in this repository, or
+2. **Contact us directly:** [atypical.consulting](https://atypical.garry-ai.cloud)
+
+We typically respond within 1 business day.
+
+---
+
+## 🔐 FAQ
+
+**Q: Can I evaluate TaLibStandard in a commercial project before purchasing?**  
+A: Yes. You can use the GPL-3.0 version for a 30-day evaluation. After 30 days, a commercial license is required for production use in proprietary systems.
+
+**Q: Does the commercial license cover NuGet packages?**  
+A: Yes — `Atypical.TechnicalAnalysis.Functions` and `Atypical.TechnicalAnalysis.Candles` are both covered.
+
+**Q: What happens if I upgrade my team size?**  
+A: Contact us. We'll prorate the upgrade to your current license period.
+
+**Q: Is source code access included?**  
+A: Yes — the source is on GitHub. The commercial license grants you the right to use it in proprietary software, not a separate private build.
+
+**Q: Do you offer volume discounts for multi-year contracts?**  
+A: Yes. Contact us for multi-year or multi-product quotes.
