We’re lean, ambitious, and obsessed with building a category-defining company. In just 12 months, we’ve grown ARR by 15x, achieved product–market fit with leading multi-billion-dollar PE firms, and expanded across the US, UK, and Europe. Backed by top VCs and senior PE execs from Warburg Pincus, KKR, and Goldman Sachs, we’re just getting started.
