Founded by former Atomico veterans CTO Harry Uglow and CEO Paddy Lambros, Dex aims to enhance talent matchmaking and improve relationships between candidates and companies.

Lambros emphasizes that effective hiring is about building lasting partnerships between employees and employers, aligning with Dex's mission.

CEO Paddy Lambros highlights that Dex saves candidates time by managing their job searches and applications.

Differentiating itself from competitors, Dex positions itself as an 'AI voice talent agent' that engages candidates through calls to understand their experiences and career aspirations.

The platform serves both passive and active job seekers, automating the job search process and eliminating the need for traditional resumes and cover letters.

In addition to job matching, Dex provides candidates with personalized interview coaching and compensation insights based on extensive market data.

Currently in closed beta, Dex has attracted around two dozen U.K. tech firms, including notable unicorns, and plans to launch publicly later in 2025.

On April 29, 2025, Dex announced a successful $3.1 million pre-seed funding round led by a16z's Speedrun fund and Concept Ventures, with contributions from notable tech industry figures.

The funding will enable Dex to expand its engineering and marketing teams as it prepares for a public launch in the U.K., followed by plans for international growth.

The AI system behind Dex gathers extensive data from public datasets and interviews with recruitment leaders to refine its matchmaking algorithms.

Dex is designed to enhance employee retention by aligning job roles with professionals' skills, ambitions, and cultural preferences.

To enhance its technology, Dex employs large language models from providers like OpenAI, Google, and Meta, continuously updating its systems to leverage the latest advancements.
