Quick Answer
A private startup valued at $1 billion or more. The term was coined by Aileen Lee in 2013 to describe the rarity of such companies.
A unicorn is a private startup company with a valuation of $1 billion or more. The term was coined by venture capitalist Aileen Lee in a 2013 TechCrunch article, chosen to reflect how rare such companies were at the time. As of the mid-2020s, there are over 1,000 unicorns globally — the status has become less rare but remains significant. The emergence of unicorns reflects the increasing scale of venture-backed companies and the availability of massive growth capital. The $1B threshold is somewhat arbitrary but serves as a proxy for the scale of success required to generate meaningful returns for large VC funds. Variants: decacorn ($10B+, e.g., Stripe, SpaceX), hectocorn ($100B+, e.g., OpenAI). Many unicorns have struggled post-IPO when public markets applied more rigorous valuation scrutiny.
In Practice
When Stripe raised its Series B in 2014 at a $1.75B valuation, it officially joined the unicorn club. Despite being only four years old, the payments company had achieved the rare milestone that historically took decades for private companies to reach. By 2021, Stripe's valuation had grown to $95B, making it one of the most valuable private companies globally and demonstrating how quickly unicorns can scale in today's market.
Why It Matters
Unicorn status serves as a psychological and market milestone that attracts top talent, premium customers, and elite investors. Reaching $1B valuation signals a company has achieved significant product-market fit and scalable business model. For VCs, unicorn investments often define fund performance and reputation, as these companies typically generate the outsized returns that drive venture capital economics and LP satisfaction.
VC Beast Take
The unicorn label has lost much of its mystique as cheap money inflated valuations across the board. What once took exceptional execution now sometimes reflects market froth more than fundamental value creation. The real unicorns are companies that combine billion-dollar valuations with sustainable unit economics and clear paths to profitability—a surprisingly rare combination even today.
