Pricing philosophy
Energy trading companies are not price-sensitive for tools that work. A single good trade covers a year of tooling costs. But you are extremely sensitive to vendor lock-in and quality.
The open source earns trust. The premium earns revenue. We will never gate features that should be free. We gate convenience, scale, and support.
