US and UK startups share identical median 22-month pace from Series B to Series C+
- US and UK median time from Series B to C+ is both 22 months
- US rounds show a wider 25th to 75th percentile spread than UK
- Earlier stage transitions generally accelerate faster in the US than UK
Across 389 consecutive Series B to Series C+ round pairs tracked from 2015 to today, startups in the United States and United Kingdom share the same median progression time of 22 months. This parity contrasts with earlier funding stages where the US consistently shows faster median transitions.
At the Series B to C+ stage, the US 25th to 75th percentile range spans 12 to 37 months, while the UK range is narrower from 11 to 34 months. This indicates slightly greater variability in US startup progression speed at this growth phase.
MEDIAN MONTHS TO NEXT ROUND BY COUNTRY AND STAGE
Comparing earlier stages reveals a different pattern: the US median time from pre-seed to seed is 20 months versus 16 months in the UK, and from seed to Series A, the US median is 15 months compared to 22 months in the UK. The US also moves faster from Series A to Series B, with a 19-month median versus 23 months in the UK.
The equal median pace from Series B to C+ highlights a convergence in growth velocity between the two ecosystems at later stages, despite the US maintaining a quicker pace at earlier rounds.
