Happy Stack Calculus Information

HSC specializes in helping startups and small businesses migrate costly AI workloads to highly optimized open source alternatives, removing dependency on frontier providers like Anthropic, OpenAI, and Gemini and returning full control of critical infrastructure to you and your team. Our clients typically see more than a 90% savings on their monthly AI bill within the first few months, and a complete reduction to only the cost of electricity once their initial hardware investment pays for itself. In addition to deployment and migration support, we help customers with machine learning pipelines covering a range of services including supervised fine-tuning, direct preference optimization, tokenization, and bespoke data aggregation tools. We support open source software and regularly contribute to the ecosystem by open-sourcing our tools and publishing research on platforms such as SSRN and arXiv.
