Mishcon de Reya has advised Cassi on its £500,000 pre-seed funding round, led by Twin Track Ventures. The round brings together expertise from defence, capital markets and growth equity. 

Cassi’s platform combines artificial intelligence, probabilistic modelling and collective intelligence to help organisations make better strategic and operational decisions. The technology enables leaders to define resolvable outcomes, quantify the probability of success and identify the factors that most influence results. Early benchmarks show Cassi’s forecasts outperform unaided human judgement by 50 percent, supporting boards and commanders in high-stakes decision-making across government, finance and critical infrastructure. 

Cassi was co-founded by Dr Keith Dear, CEO and former Expert Adviser to the UK Prime Minister, and Al Brown, Chief Technology Officer and former Royal Engineer. The company draws on deep experience at the intersection of national security, cognitive science and advanced computing. 

The Mishcon de Reya team was led by Attilio Leccisotti who commented: "We’re delighted to have advised Cassi on this initial round. Having worked with such a pre-eminent founding team, who are real experts in their field, we're really looking forward to supporting Keith, Al and the team going forward and witnessing Cassi grow."
