Romania-based UiPath, which develops AI-based bots that automate mundane enterprise tasks, confirms it raised $153M Series B at $1.1B valuation led by Accel
Context & Ripple Effects
UiPath's trajectory has been unusually compressed: it raised a $30M Series A led by Accel in April 2017 at an estimated $109M valuation, and less than a year later the same lead investor has taken it to a confirmed $153M Series B at $1.1B — a tenfold valuation step in eleven months. The earlier reports of a ~$120M round at $1B+ made the unicorn status likely; this confirmation settles both the size and the price.
The round matters because enterprise back-office automation was still an unproven category at this scale, and Accel backing it twice signals conviction rather than opportunism. The subsequent coverage shows the bet compounding: a $225M Series C at $3B six months later, an upsized $265M total Series C, and eventually a $225M Series E at $10.2B in 2020.
First-order effects
- UiPath enters the unicorn club with fresh capital to scale its AI-based bots across enterprise customers, with Accel now holding a doubled-down position from Series A through B.
- Accel's early check converts into one of its most valuable positions on record, validating its strategy of leading small early rounds in Eastern European founders and following on aggressively.
Second-order effects
- The speed of UiPath's re-rating forces other enterprise automation vendors to raise at comparable valuations or concede the category's financing benchmark to a single company.
- Accel's later mega-fundraises — including a $4B Leaders fund and a $5B pool explicitly aimed at writing large late-stage checks globally — mirror the follow-on playbook this round established: hold winners and keep funding them at growing check sizes.
Third-order effects
- If the pattern holds, robotic process automation consolidates around a few heavily capitalized platforms, with later-stage investors (CapitalG, Sequoia, Alkeon appear in the later rounds) crowding in behind the original lead.
- Romania-origin enterprise software reaching decacorn-scale private valuations points to a structural shift in where category-defining automation companies are built and who funds them.
The trend: Enterprise automation startups are compressing the path from early-stage bet to multi-billion-dollar platform, with lead investors like Accel using successive mega-funds to concentrate capital in breakout portfolio companies.
