Evaluation of Pre-IPO companies: what metrics to look at before investing

Evaluating a pre-IPO company means checking whether the entry price matches the quality of the business, not only whether the company will grow. The key metrics are revenue and its growth, gross margin, net revenue retention (NRR), burn rate and runway, unit economics, the Rule of 40, valuation to revenue and the round's structure, including liquidation preferences.

In pre-IPO deals, money is lost not only on weak companies but also on good ones bought too expensively. A private company's price changes only at a new round or trade, so it can lag behind reality. If the market is new to you, start with how the pre-IPO market works.

Why can a strong company be a poor pre-IPO investment?

Because the return depends on the price paid, not on the company alone. If the valuation already assumes the best case, even solid growth may leave no room for a gain.

In early 2021 Instacart raised money at a $39 billion valuation, or $125 a share. In September 2023 it priced its IPO at $30 a share, about $10 billion on a fully diluted basis, CNBC reported. The company had not failed: it had to cut its price sharply to attract public investors.

The same revenue can justify very different valuations, as explained in how investors value startups and why revenue alone proves nothing.

Which metrics should you check before investing in a pre-IPO company?

Eight metrics cover most of the picture: how the company earns, how efficiently it grows, how long its cash lasts and what exactly the investor buys.

None of these has a universal threshold, and ARR, NRR or "adjusted EBITDA" are defined by the company itself. For public companies, the SEC's guidance of January 30, 2020 expects a clear definition of each key metric and of how it is calculated. Ask a private company for the same, plus the period and whether the figure is audited.

How do you tell high-quality revenue from bought growth?

Start with the business model, then check whether revenue repeats. High-quality revenue comes back each year from customers who stay and spend more, at a margin that leaves money for the business.

$100 million of ARR in software with high retention is not the same as $100 million of turnover in a marketplace with a thin commission. Questions to ask:

• Who pays, for what, and why they will keep paying.
• How much revenue depends on the largest customers.
• Whether gross margin rises or falls with volume.
• How long it takes to recover the cost of winning a customer.
• Whether cohorts, customers who signed up in the same period, keep paying: growth bought with discounts looks durable only on a chart.

How do burn rate and runway show whether the company can reach an IPO?

Runway is cash divided by monthly net burn, in months. If it is shorter than the road to an IPO or break-even, the company will need another round on terms that affect existing shareholders.

The burn multiple shows the cost of growth: net burn divided by net new ARR. David Sacks of Craft Ventures, who proposed it in April 2020, reads 3x or more as a sign that product-market fit may be weaker than it looks.

Closer to an IPO, growth alone is not enough: investors look for a path to profit or steady cash flow. How expectations change by stage is covered in the guide to Series A, B, C and D rounds.

What do the Rule of 40 and revenue multiples say about the price?

They show whether growth and profit support the valuation and how it compares with listed peers. Neither is a verdict on its own.

In a February 2015 post, investor Brad Feld described the Rule of 40 for SaaS companies with at least $50 million in revenue, using EBITDA as the profit measure: growing 50% a year, a company can lose 10%; growing 20%, it should earn 20%. Compare scores only on the same profit measure.

Aswath Damodaran's January 2026 data put the aggregate EV/Sales of 309 US-listed system and application software companies at 11.4x, against about 4x for all 5,994 US companies in the set. Large companies dominate these totals.

A premium to listed peers needs a reason: faster growth, higher retention or better margins. Otherwise the investor pays for access. A useful test is what the stake would be worth if the company listed at its peers' multiple, after fees and a lock-up.

How can the structure of the round change your return?

The terms decide who is paid first, and how much, when the company is sold or lists. Two stakes at the same headline valuation can return very different amounts.

• Liquidation preference. Preferred stock is paid before common stock; at 1x, holders get back what they invested.
• Participation. Non-participating preferred takes its preference or its share as if converted into common stock, whichever is larger; participating preferred takes both.
• Seniority. A large late round can be paid ahead of everyone else.
• Vehicle. Through an SPV or a fund, the investor owns an interest in the vehicle, pays its fees and may face resale limits.

In the 166 financings Cooley handled in Q2 2026, 95.8% had a 1x preference and 96.4% used non-participating preferred stock. Harsher terms deserve a question about whom they protect.

How does liquidity affect the price you should pay?

Private shares cannot be sold at the click of a button, so the entry price should compensate for years of waiting and an uncertain exit. Otherwise the investor carries that risk for free.

Exit routes include an IPO, a tender offer, a secondary sale, a buyback or a sale to a strategic buyer, each with its own timing and discount. Some companies stay private for years. The details are in how pre-IPO differs from an IPO and the complete guide to pre-IPO investing.

What are the risks of relying on these metrics?

The numbers may be incomplete. Pre-IPO investments can lose part or all of their value; good metrics reduce uncertainty but do not remove it.

• Data. Private companies generally do not publish audited quarterly reports.
• Information gap. A seller on the secondary market may know more than the buyer.
• Valuation. Multiples move with the market, as the Instacart case shows.
• Timing. An IPO can be delayed for years or never happen.
• Structure. Preferences and fees reduce what reaches an individual investor.
