The British Business Bank and the Sovereign AI Fund have backed the artificial intelligence developer in a record-setting seed round.
"David Silver is a generational talent who has consistently been on the cutting edge of AI development. Ineffable Intelligence has the potential to produce a paradigm shift in our scientific and technology landscape, and we are incredibly excited to be supporting him and his team in this endeavour."
The London startup secured $125m at a $1.5bn valuation to scale its conversation search technology.
"To make your company’s context work for you"
The Series A round was led by Atomico with participation from Index Ventures, Norrsken VC and Daphni.
"Invention is how we solve humanity’s biggest challenges, yet the systems that protect those ideas are decades out of date. AI will redefine how global organisations innovate over the next five years, turning IP from a cost centre into a growth driver. The companies that adopt Ankar now will shape the future of innovation."
The seed round was led by Index Ventures with participation from multiple venture firms and angel investors.
"Our platform dramatically streamlines this process and mountains of documents which slow down research today. But improving efficiency is only the beginning, building AI into the invention process, along with the inventors allows inventors to fundamentally expand the horizons of what we can imagine creating. We believe Ankar is creating the foundation for the next generation of breakthrough technologies."
Battery Ventures led the Series A round to support platform development and US expansion.
"Support is no longer just about closing tickets – it’s about building long-term relationships. The migration to collaborative, real-time channels is changing the way businesses interact with customers. Plain is the platform designed for this new reality, helping companies deliver support that’s fast, effective, and aligned with their customers’ needs."
