How Venture Debt Warrants Work: A Founder's Guide

You need $2-5 million to hit your next growth milestone, but giving up 25% equity in a Series B feels premature. This is the classic founder’s dilemma. While venture capital is a common path, the dilution can be steep. This is where venture debt becomes an attractive option, but it comes with its own unique terms, specifically, warrants.

So, what are they? And more importantly, how much of your company are you really giving up?

This guide breaks down how venture debt warrants work, what to expect, how to measure the risk, and what it means for your cap table.

What Is a Warrant in a Venture Debt Deal?

A warrant gives a lender the right, but not the obligation, to buy a specific number of your company’s shares at a preset price (the “strike price”) before a set expiration date.

Think of it as a long-term stock option for the lender. They provide the loan, and in return, they get a chance to share in your company’s future success. If your company’s value grows, they can exercise the warrant, buy shares at the original, lower price, and see a return. If not, the warrant expires worthless, and they are not required to do anything.

Most warrants last 5-10 years.

Why Do Lenders Ask for Warrants?

Lenders use warrants to balance their risk and reward. Unlike equity investors, a debt lender’s primary return comes from interest payments. Their upside is capped. Warrants give them a small piece of equity potential to compensate for the risk they take on, especially with high-growth, pre-profitability tech companies.

Let’s look at the funding landscape:

Chart comparing risk levels of bank loans, venture debt, and venture capital.
  • Banks: Banks take on the least risk. They lend to stable, profitable companies with hard assets. They protect themselves with strict rules (covenants) and, in return, offer low interest rates without asking for warrants. Most early-stage SaaS companies don’t qualify for bank loans.
  • Venture Debt Lenders: These lenders work with high-growth companies that have product-market fit but may not be profitable yet. A SaaS company with strong recurring revenue but few physical assets is a perfect example. To balance this higher risk, lenders charge higher interest rates and ask for warrant coverage.
  • Venture Capital (VC): VCs take the most risk by investing in early-stage companies for a significant equity stake. Their entire model is based on one or two companies in their portfolio achieving a massive exit (like an acquisition or IPO) to pay for all the others that fail.

Warrants place venture debt between the low risk of a bank loan and the high dilution of a VC round.

How Much Equity Dilution Should I Expect from Warrants?

The amount of potential dilution is defined by the warrant coverage, expressed as a percentage of the total loan amount. Typical coverage ranges from 5% to 30%, depending on the risk of the deal.

Here’s a simple example:

  • Loan Amount: $4 million
  • Warrant Coverage: 10%
  • Warrant Value: $400,000 (10% of $4M)

This means the lender receives a warrant giving them the right to purchase $400,000 worth of your company’s stock.

The good news? This does not mean you give up $400,000 of your company. The lender must still pay the $400,000 to exercise the warrant and buy the shares. If exercised, this warrant typically translates to just 1–2% of total equity dilution. It’s a small slice of ownership, not a controlling stake.

How Is the Warrant Strike Price Determined?

The strike price is the price per share the lender will pay if they decide to exercise the warrant. A lower strike price is better for the lender, as it creates more potential profit.

There are three common ways to set the price:

  1. Price of the Last Equity Round: This is the most straightforward method. The strike price is set at the per-share price from your most recent funding round (e.g., your Series A).
  2. A Negotiated Value: If you haven’t raised a recent round, you and the lender can agree on a fair company valuation to determine the strike price. This usually involves reviewing your revenue, growth rate, and market comparables.
  3. A Discount to a Future Equity Round: If you plan to raise a new round soon, the strike price can be set at a discount (e.g., 15-25%) to the valuation of that future round. This gives the lender a guaranteed return for taking on risk before the new valuation is set.

Are There Any Upsides to Warrants for Founders?

While warrants represent potential dilution, they offer a few benefits:

  • Access to Less-Dilutive Capital: The primary benefit is getting the growth capital you need without the 20-25% dilution of a typical equity round.
  • Future Cash Injection: If the lender exercises the warrant, your company receives cash for the shares sold. It's a small but helpful capital infusion.
  • Alignment of Interests: A lender holding warrants is more invested in your long-term success. They want to see your valuation grow, making them a more aligned partner than a traditional creditor.

What Are the Risks of Issuing Warrants?

For founders, the main risk is straightforward:

  • Future Equity Dilution: If your company succeeds and the lender exercises its warrants, your ownership stake and that of your existing shareholders will be diluted. While small, it still impacts the cap table.
  • Selling Shares at a Discount: If your company’s valuation skyrockets, the lender gets to buy shares at the original, much lower strike price. This is the cost of securing the debt when you did.

For lenders, the risks are greater. Warrants have a finite life, offer no voting rights, pay no dividends, and can expire worthless if the company’s value doesn’t increase past the strike price.

Founder FAQs

1. Can I negotiate the warrant coverage on my loan?

Yes. While lenders often start with a standard range, coverage is negotiable, especially if you have multiple term sheets, strong financial metrics, or a recent funding round that reduces perceived risk. You can push for lower coverage, a shorter warrant term, or alternative structures like a success fee to reduce potential dilution.

2. What happens to warrants if my company is acquired before they’re exercised?

In most cases, warrants either convert into shares before the sale or are “cash-settled,” meaning the lender receives the value they would have earned had they exercised. How this plays out depends on the warrant agreement, so review it carefully to understand if you’ll need to account for this payout during M&A negotiations.

3. Can warrants be repurchased or cancelled after the loan is repaid?

Sometimes. Some lenders will agree to cancel or sell back unexercised warrants if you repay the loan early or after a set period. This typically requires a negotiated buyback price. If reducing future dilution is a priority, it’s worth discussing this option when structuring the deal.
