The six most valuable companies in the world were once venture-backed startups. Alphabet, Amazon, Apple, Meta, Microsoft, and Nvidia, started out as small, private companies. They raised money from venture capitalists (VCs) to fuel their growth. They developed new technologies—search engines, online marketplaces, personal computers, social networks, operating systems, and graphics processing units. And then they did what most fast-growing private companies used to do—they went public.
Venture-backed startups used to have predictable lifecycles. A startup would raise a new round of capital every twelve to twenty-four months. After several rounds, the startup’s founders and employees would want to convert their shares to cash, and its VCs would need to deliver returns to their limited partners (LPs). The startup would exit the private market, so its shareholders could exit their investments. For some startups, the exit was an initial public offering (IPO). For others, the exit was an acquisition by a larger company.
The predictability of the startup lifecycle made the private-public divide coherent. When a startup grew enough to have a significant impact on society, it would usually become a public company or be sold to one.
Around the turn of the century, though, the startup lifecycle began to change, and the private-public divide began to blur. The number of IPOs fell precipitously. The share of startups exiting by acquisition rose. Many startups stayed private even as they grew into large companies. Some became “unicorns”—private companies valued over $1 billion. READ MORE
