Pre-Seed
£2.3M

The pre-seed round was led by Outward VC and will support team expansion and international growth.

"Strategic procurement is one of the last frontiers for true automation because so much of it remains powered by intuition. Throughout my previous roles, I saw just how much instinct drives results, but also how much time is wasted and how much value is being left on the table because instinct alone can only go so far. Our goal at Monq isn’t to replace that judgment but to amplify it. By empowering procurement teams with strong, actionable, data-driven and intelligent insights, we’re giving enterprises the speed, clarity and confidence to negotiate at an entirely new scale while unlocking billions in hidden deal flow, value and efficiency before that value is lost to the company."
— Yasin Bostancı, Co-founder and CEO
Seed
£1.5M

The financing round was led by Cornerstone with backing from several early stage investors.

"Rising care costs, an overstretched social care system, and the demands of daily life can leave families feeling guilty and stretched thin as they think about their elderly loved ones. That’s why I’m thrilled to back George and Alex as they build Gladys, a managed social care platform that makes it easy to find and book trusted caregivers and companions. Their mission is close to my heart: giving families peace of mind and helping everyone grow old with dignity, in the home they cherish, for as long as possible."
— Rodney Appiah, Chairman
Pre-Seed
£1.0M

The AI-native RegTech startup has secured pre-seed funding to accelerate product innovation, integrations, and team growth.

"While we’re not publicly disclosing specific figures, we’ve raised sufficient capital to execute the next phase of our growth. We’re investing in three core areas: product innovation (deepening our AI-native capabilities with richer regulatory intelligence and more automated workflows), ecosystem integrations (expanding our ability to connect seamlessly with existing financial systems and compliance tools), and team growth (hiring specialists in financial crime ops and AI to support our growing customer base and accelerate execution). Everything we do is focused on solving 95% of the problem that begins after an alert is triggered."
— Kartik Dabbiru, CEO
