Dealstack, a platform founded by former Kirkland & Ellis Partner Joel Arnell and ex-Oaktree Capital investor Seb Lapinski, has closed a £4.3 million ($5.5 million) seed funding round. The raise includes participation from current and former professionals at firms such as Paul Weiss, Kirkland & Ellis, Latham & Watkins, KKR, CVC, TA Associates, and Goldman Sachs.
Dealstack automates key workflows—valuation waterfalls, employee equity and ownership tracking, structure charts, contract management and more—within a single platform built specifically for private capital. The company aims to replace outdated manual processes with structured, AI-driven solutions.
In just two years, Dealstack has been adopted by over 30 private capital firms representing $2.6 trillion in AUM. This includes 6 of the top 10 global firms by funds raised and 8 of the top 10 in Europe. It is also used by 7 of the top 10 global law firms by deal value and 9 of the top 10 in Europe.
Dealstack’s platform is built on a private capital-specific data model unique to each customer, enabling secure, AI-powered automation of complex workflows. The company positions itself as the infrastructure layer required to bring trusted AI into private capital operations.
