OpenPR·medium signal

BlackMagic AI announced public availability of its open-source GTM Engineering platform on April 28, positioning as the leading open-source alternative to Clay for go-to-market teams. Every agent, enrichment step, and workflow primitive is open, inspectable, and modifiable — teams can swap in their preferred LLMs, plug in proprietary data sources, and run the entire stack inside their own cloud. Early users report meaningful reductions in list assembly time and improved reply rates from better AI-driven personalization, all without vendor lock-in or per-credit pricing.
