Recently launched Productboard Spark, an AI-powered product agent that automates workflows from customer discovery through launch orchestration.

Luminary Cloud is a cloud-based SaaS platform that enables engineers to encode physics into AI, dramatically accelerating computational simulations for product design and optimization. The platform runs high-fidelity CFD and thermal simulations 100x faster than legacy software by leveraging GPU and cloud processing, with an AI copilot (Lumi AI) that automates tedious setup tasks like mesh generation. Customers across aerospace, automotive, and sporting equipment industries use Luminary to compress months of iteration into days or hours, with usage-based pricing that scales from quick conceptual designs to complex analyses. Key differentiator: AI-driven automation of simulation workflows combined with near-real-time cloud performance, versus traditional per-user licensing models.
