Addition, a venture capital firm, led a $100m Series D round in Snorkel AI, an AI development platform, with participation from Prosperity7, Greylock, Lightspeed, BNY and QBE Ventures. “We are seeing a surge of momentum around agentic AI, but specialized enterprise agents aren’t ready for production in most settings. Enterprises need domain-specific data and expertise to make this a reality. We’re excited to deliver on this need and help AI innovators develop expert data to bring their LLM and agentic systems into production with our new offerings, which round out Snorkel’s unified AI data development stack,” Alex Ratner, Snorkel AI Co-founder and CEO.
