The most striking aspect is the speed: the company went from a US$8 billion valuation in December to US$11 billion in March 2026, and now to US$15.5 billion in September, according to the chronology reported by TechCrunch. In total, Harvey has raised more than US$1.55 billion since 2023, with at least eight priced capital rounds in that period, five of them since 2025 alone.
