What Is Venture? An Interstellar Journey Toward a New Definition
Over the past few years, there has been a rollercoaster of enthusiasm, pessimism, opportunism, skepticism, and confusion within the venture capital industry. How a company identifies, or how we identify a company, changes depending on where the company sits in its life, what industry it is in, and how the broader universe of capital markets choose to participate in the company’s journey.
This has prompted an increasingly common and fundamental question: “What is venture?” Or, depending on the mood, a more tense and concerned, “What is venture?!”
Given this, it seems worth:
- Defining what we know venture is.
- Considering and asking the question, “Is this venture?”
- And identifying a new capital market dynamic, where we boldly state, “This is venture!”
Venture is this: A traditional definition
When speaking to clients about what venture is, I often quote Joseph Schumpeter or Nikola Tesla. Their works describe the entrepreneur’s obsessive commitment in a way I have found evocative: According to Tesla, “the entrepreneur’s emotion can cause one to forget food, sleep, friends, love, and everything.”
This start of the journey is where venture capital traditionally invests: at the intersection of innovation and the entrepreneur at the company formation stage, and post this fusion event, a new star is born.
The journey of the entrepreneur can be thought of like this star: a nebulous idea catalyzed by venture capital to create a celestial body. Value added venture capital, through subsequent rounds, continues to fuel its rise as it ascends through the atmosphere leading up to what is believed to be the ultimate celestial moment: the IPO, the supernova.
In venture speak, investing in a seed or series A for as little as approximately $2 million on a $10 million valuation and following through subsequent rounds up until the IPO is the ultimate textbook journey.
The most recent successful venture backed IPOs have tapped the public markets at valuations between $5 billion and $10 billion. From a return standpoint, this translates to a potential 500x to 1000x return for the original investor who participated in the protostar stage. Examples of recent IPOs that fit this valuation profile include Astera Labs, Reddit, Rubrik, and ServiceTitan.
Since venture has been an institutional asset class, the company life cycle described above is mostly accepted as what venture is.
But for some, the journey does not end with IPO.
Is this venture? A blurred line in modern times
More recently, the line defining venture has blurred, most notably between venture capital, private equity, and even the public markets which are at times acting as the pathway.
If you look back at some of the largest private equity deals over the past two years, they are public to privates in what were once successful venture backed companies that IPO’ed but, regrettably, could not achieve market dominance. To use the metaphor from above, they gave in to gravity and reentered the private market atmosphere in search of value-added capital.
There are various case studies for the “why,” but for many, it is a valuation and transformation arbitrage to help a company on its journey from “grow at all costs” to the “rule of 40.” But trust, once the private market mission is complete, the likely goal is to harness escape velocity following a slingshot assisted orbit around the moon, to again enter the public domain — as a mature, growing, profitable company.
Recent examples here include Qualtrics, Squarespace, Nuvei, Darktrace, and Alteryx. The facilitators were well known private equity shops including Advent, Permira, Silver Lake, Thoma Bravo, Insight, among others. These are firms that define private markets and now serve as mission control for the companies they own.
Prior to their successful IPOs, these companies were in venture portfolios of funds managed by Accel, Index, Insight, Sequoia, and even Ryan Reynolds. We believe most limited partners (LPs) would consider this to be an A-list of venture managers who, like their bigger siblings above, also define their own private markets. The companies noted above were key contributors allowing these market definers to achieve A-list status.
What is interesting about the first venture definition versus this second venture definition is that these technology companies are being traded within the capital markets at valuations between $5-10 billion using the public market as a kind of wormhole.
For many purists, it is a stretch to call this venture. But if we accept the company is a healthy grower, aspiring to define its market, recalibrating, and course correcting, on a mission to achieve better, faster, cheaper in this trade through the wormhole, can we accept that this is venture under a more liberal definition?
If your answer is still “no way!” then bear with me for just a minute more.
This is venture: Defining the universe!
Now that we have established venture’s traditional journey from entrepreneur and an idea to $5-10 billion IPO, transitioning in and out of the public and private markets at the same $5-10 billion value, let’s discuss the more provocative cohort that has emerged as market leading and market defining companies, choosing to totally bypass the IPO — at least for now.
Dare we call these iconoclasts the Masters of the Universe?
This cohort, which includes SpaceX, ByteDance, Stripe, Databricks, OpenAI, Anthropic and others are lining up in this unprecedented Space Race. They continue to raise venture capital from traditional venture firms, secondary investors, private equity, sovereign wealth funds, and leading financial institutions.
They are not raising $2 million on $10 million, or even $100 million on $2 billion. They are raising $1 billion, $5 billion, $10 billion on $50 billion, $100 billion, $300 billion values. These valuations are 10-50 times the values of the most recent, and so-called “most successful” venture-backed IPOs.
Recently, this part of the capital markets has caused much debate. At the core is the question, “is this venture?” It is investing in emerging companies in emerging industries. These industries have current and future total addressable markets bigger than any we have ever seen. Some experts estimate the markets for Space and Artificial Intelligence will each reach $2-4 trillion within 10 years.1 These companies are on a one-way mission to define their markets. But it is not $2 million on $10 million, it is $10 billion on $100 billion.
Regardless of whether it is venture or not, it is a very large private market investment opportunity that is attracting attention, enthusiasm, and capital. And, if we revisit Schumpeter and Tesla, they are embodied by words like disruption, innovation, productivity, growth, thrill, success, and emotion, “which can cause one to forget food, sleep, friends, love, and everything.”

The closing from the captain’s log
At the beginning of Star Trek, Captain Kirk delivers his iconic monologue. It famously starts, “Space, the final frontier.”
I believe this to be the true venture journey: the point of inception when the entrepreneur and an idea together combine at the company formation stage, seeking to achieve the most ambitious of all outcomes, the IPO.
And then the protagonist entrepreneur pivots to, in Kirk’s words, “exploring strange new worlds, seeking out new life and new civilizations.” The entrepreneur encounters the public to private transaction, challenging what they think they know or believe to be the truth. The public market is supposed to be the end of the venture journey, the celestial moment, not the beginning. Is this venture?
Not long after, they come across life forms they have never seen before, in markets so vast they are almost immeasurable. Growing at 100+% per year, defining their markets, but 25 – 50 times the size of their closest peer, “boldly going where no company has gone before!”
Today, this is venture — and what an exciting journey it continues to be.
