Shares in the data-infrastructure start-up jumped on their first day of trading as it set out plans to build a 'neutral' record of AI agent transactions.
Roundhouse AI (AIM: RHAI) made a strong start to life as a public company on Tuesday, with shares jumping more than 20% on its first day of dealings after the firm raised roughly £1.6m to fund its push into data infrastructure for autonomous AI agents.
The float priced new shares at 5p apiece via a placing and offer, valuing the business at around £14m at admission. Investors quickly bid the stock up to around 6.25p, suggesting appetite for early-stage exposure to the fast-growing theme of AI agents transacting with one another and with businesses.

Roundhouse's pitch centres on acting as an independent referee for the emerging 'agent economy', logging payments and interactions between AI agents and businesses to build a dataset that can underpin identity verification and reputation scoring. The group launched a free dashboard in September and said it is prioritising data coverage over near-term revenue.
Chief executive Matthew Lodge said AI agents were already beginning to pay each other and pay businesses, and argued the market needed 'a neutral record of who is paying, who is getting paid, and what it costs', a gap he said Roundhouse is positioned to fill.
Management has flagged plans to monetise the platform through paid products, including Agent Reputation Scores and an aGDP Index tracking AI-agent activity, once data coverage is broad enough to support reliable scoring. With no material revenue expected yet, the stock's near-term trajectory is likely to hinge on how quickly the company can scale usage of its dashboard and demonstrate traction among AI developers and enterprises.
