The inaugural Scaling Stateside 50 report by US Expansion Partners (USXP) highlights a significant gap between the domestic success of European B2B scaleups and their readiness for the US market. The 50 assessed companies achieved an average commercial strength score of 86 out of 100, but only 17 out of 100 for US market readiness.

The assessment reveals that 96 per cent of the companies lack essential US infrastructure, such as corporate entities, employer identification numbers, or payroll systems. Furthermore, over 80 per cent of these firms have no US-based employees, trademarks, or patent filings. Fintech and cybersecurity sectors currently lag behind SaaS and deeptech in US operations.

The ranking is based on a Foundation Score, which measures commercial performance, and a US Readiness Score, which evaluates market entry preparations. To qualify, companies must achieve a Foundation Score of at least 55. The list includes 50 businesses from 15 countries, with the UK and Germany each contributing 12 companies.

USXP plans to update the ranking quarterly and intends to track progress toward US readiness starting in the first quarter of 2027. The project is supported by partners including Wilson Sonsini Goodrich & Rosati, HSBC Innovation Banking, Carta, Frazier & Deeter, Dealroom.co, and London & Partners.
