AI recruiting startup Dex raises $5.3 million seed round, bringing total funding to $8.4 million

Dex, founded in early 2025 by Paddy Lambros, raised a $5.3 million seed round led by Notion Capital with participation from a16z Speedrun, Concept Ventures, and angel investors from OpenAI and other firms. The startup has now raised $8.4 million total, including a $3.1 million pre-seed round last year.

Dex operates as an AI talent agent: job seekers have conversations (voice or text) with an AI agent that asks about experience and ambitions, then surfaces matching roles from curated job openings, helps with company research, compensation benchmarking, and interview prep. The AI is built on models from Google, Anthropic, and OpenAI, paired with a proprietary matching engine. Dex charges employers 20% to 30% of a hired candidate's salary.

More than 15,000 engineers have signed up, and over 50 technology companies—including Lovable, ElevenLabs, Synthesia, Granola, and Fyxer—use the service. Since beginning to charge in late 2025, Dex has reached a roughly $1.8 million annualized revenue run rate.

Dex plans to open offices in New York and San Francisco later this year, expanding from its current headquarters in London.
