The Full Picture

1. The growth happened before you could buy a share

In June, SpaceX went public.

Six months earlier, a private tender valued it near $800 billion. It closed its first public day around $2 trillion.

Everything under that number — twenty-four years of launches, Starlink, and government contracts — was built before a public investor could buy a single share. Public buyers got the finished building at the finished price.

If your portfolio is all public markets, that is your exposure now. The map ends at the ticker. The territory doesn’t.

One thing straight up front: SpaceX is an outlier. Most private companies fail or return far less than that, and buying private means paying today’s price, not capturing yesterday’s rise. That is exactly why this market takes discipline. You’ll see that word a lot on this page.

2. There are three equity markets. You own one.

Public — listed, liquid.
Late-stage private — multibillion valuations, real revenue, not listed yet.
Venture-stage private — the start-ups building what’s next.

Most portfolios: 100% the first, 0% the rest.

That used to be fine. In 1999 the median company going public was five years old. By 2024 it was fourteen. Nine more years of growth now happens behind the curtain, funded by private capital that didn’t exist at scale a generation ago. That is how SpaceX showed up at its IPO already worth trillions — and it’s where much of the next decade’s value is being created right now.

You didn’t do anything wrong. The rules moved.

Zero private exposure is no longer a neutral default. It’s a decision to skip two of the three equity markets.

Maybe the right decision — this isn’t for everyone, and private companies can lose everything. But make it a decision, not an accident.

The rule I keep coming back to: access gets you in the room; discipline decides what belongs.

Two things about the guide you’re walking with: every PEP fund is audited by an independent firm, and we write five memos before we buy anything. You’ll see both below.

3. Don’t take my word for it

In August, Vanguard — the firm that put low-cost index investing on the map — published a framework for how much private equity belongs in a portfolio.

Their range: 0% to 40% of your total equity allocation.

Think about who is saying that. Vanguard’s entire thesis is “own the whole market.” When they write a framework for the part of the market that has left the index, that isn’t marketing. That’s an admission.

Three things to notice. They lead with zero; a framework that can’t say zero isn’t a framework. They measure against your equity allocation, not your overall portfolio — this is equity, just unlisted. And their stated condition for making it work: access to highly skilled managers at a reasonable cost.

To be straight: Vanguard’s framework covers private equity broadly, not late-stage companies specifically, and none of it is investment advice. The right number for you depends on your liquidity needs, time horizon, and risk tolerance — a conversation worth having with your advisor.

4. How a share with no ticker changes hands

There’s no exchange for private companies. So how does anyone buy a share?

Someone sells one. An early employee with eight years of paper wealth and a mortgage. An early-stage fund that needs to return capital to its own investors. A company running a tender offer so its people can take some money off the table. Every share of a private company is owned by somebody, and some of them want liquidity before the IPO.

That’s the secondary market. It’s real, it’s large, and it’s hard. You have to find the seller, agree a price with no public quote, clear the company’s transfer restrictions, and then hold a position with no guaranteed exit. Almost nobody can do that alone. That is the work PEP does — and finding the seller is where we start with an edge.

PEP is a spinout of Alumni Ventures, whose 40-plus investment professionals sit on more than 1,400 cap tables. When a shareholder in one of those companies wants liquidity, we are often an early call — not because we outbid everyone, but because we already know the company, the board, and the seller. Most buyers in this market start with a search. We start with a map.

Two ways in:

Funds — one commitment, a diversified portfolio of late-stage positions.
SPVs — one company per vehicle, for investors who want to size a specific position.

So far: Fund I holds SpaceX, Anthropic, Stripe, Revolut, Clay, Open Evidence, Supabase, Whoop, and Deepgram — all bought private, before any IPO.* Getting in isn’t getting in cheap. You pay today’s price, and these positions are illiquid and can lose value.

5. Five ways a great company becomes a bad investment

The most expensive sentence in private markets: “It’s [famous company] — how risky can it be?”

Quite risky. Access to a famous name feels like a strategy because access is scarce. Scarcity isn’t quality. Companies can carry multibillion-dollar valuations and no revenue. A secondary investment goes wrong in five distinct places, and we write a separate memo to try to break every deal in each one:

The company — durable business, or big-name backers and momentum? Sellers usually know more than buyers.
The price — a great company doesn’t stop you overpaying. It makes overpaying feel safe.
The counterparty — the seller, the SPV manager, the administrator. Does each one need this to close cleanly?
The asset — are there real shares at the bottom of the stack? A vehicle in a vehicle in a vehicle is where equity goes missing. It’s also why every PEP fund is independently audited: the shares get counted by someone who doesn’t work for us.
The deal — the documents. Lockups, transfer limits, carry, and exit mechanics that only matter when things go wrong.

Each memo is a real gate. Each has killed a deal. That costs us: we move slower, we lose allocations, we’ve passed on names that would have made great marketing.

Don’t fall in love with the company before you understand the investment.

6. Build the portfolio. Don’t pick the winner.

Read Fund I by job, not by logo:

SpaceX (now Nasdaq: SPCX) — bought private; listed in June.
Anthropic — the model layer of the AI economy
Stripe — the rails under digital commerce
Revolut — consumer finance, digitized
Clay — applied AI for sales and marketing
Open Evidence — applied AI for doctors
Supabase — developer infrastructure, the backend for AI code
Whoop — subscription health platform blending AI, software, a wearable, and labs
Deepgram — the infrastructure under voice AI

Different markets, business models, and exit paths. On purpose. Each one cleared the five gates — and then a sixth question no memo can answer: right deal, but right fit next to what’s already owned?

That sixth question is why PEP has both funds and SPVs. The fund is your diversified base across the late-stage market. SPVs let you size a specific name on top of it. You build the portfolio; we build the access and run the diligence.

The most important sentence on this page: the temptation is to find the one company that changes everything. The job is a portfolio that works without every assumption being right.

One listing proves a path exists — not that every position finds one, or that the exit price satisfies.

7. What the SpaceX IPO actually taught

In June, the theory behind this page stopped being a theory.

SpaceX closed its first public day near $2 trillion — 2.6x its last private price, six months earlier. The IPO didn’t start the story. It put the story on general release.

Fund I investors held a position bought private and carried to a public listing. That’s the thesis working mechanically. Exits are real, not theoretical.

The honest part: private pricing can be wrong too. Growth slows. Liquidity takes longer than anyone plans. Some companies never exit. You can lose everything. Anyone who tells you otherwise is selling access, not judgment.

But the voice saying “I’ll just wait for the IPO” — you now know what waiting bought SPCX buyers. Sometimes that’s still the right call. It’s no longer the default one.

So the question is yours: should scaled private companies have a deliberate place in your portfolio?

8. The one formal step before Fund 2

If your answer is “not for my portfolio” — good. That’s an informed decision, and it was the point of this page.

If it’s “worth a serious look,” there is one formal step before you can invest in any PEP fund or SPV: verifying your accredited status. Here’s exactly what it involves.

Who: an independent third-party verifier, North Capital — not PEP. Your documents go to them. We get a yes or no.
What: an SEC requirement for offerings like our flagship fund and SPVs. A CPA or attorney letter, or income/asset documents reviewed by the verifier.
How long: about ten minutes of your time; confirmed within a few business days.
What it commits you to: nothing. It’s a credential, not an investment. When the next fund or SPV opens, you read the offering documents on your schedule instead of racing a deadline.

What’s on the other side of it: funds that are independently audited every year, positions sourced through the Alumni Ventures network, and a team that writes five memos before it buys anything.

The same rule that kept this market closed to most investors is the one that opens it to verified ones. Clear the step now, before there’s anything to decide.
