Can I Sell Some of My Own Shares When We Raise Our Next Round?

You’ve spent years building your startup.

You’ve accepted a modest salary, worked long hours, and reinvested nearly everything back into the business.

Now you’re preparing for a successful fundraising round.

The valuation looks promising, investor interest is growing, and for the first time you’re wondering whether you can sell a small portion of your own shares.

You’re not planning to leave the company. You simply want some financial security after years of taking personal risk.

Many founders eventually ask this question. Founder secondary sales have become more common in venture-backed companies, particularly as startups stay private for longer. However, selling your own shares involves much more than finding a willing buyer. Company agreements, investor approvals, transfer restrictions, and tax consequences all play an important role in determining whether a secondary sale is possible.

What Is a Founder Secondary Sale?

A founder secondary sale occurs when an existing or new investor purchases shares directly from a founder rather than buying newly issued shares from the company.

Unlike a primary financing:

• The company does not issue new shares.
• The company does not receive additional capital.
• The founder receives the sale proceeds directly.

This allows founders to obtain some personal liquidity while continuing to own and operate the business.

Your Shares May Not Be Freely Transferable

Many founders assume they can sell shares they already own whenever they choose. In reality, startup equity is often subject to contractual restrictions.

Stockholder agreements commonly require:

• Board approval before shares can be transferred.
• A Right of First Refusal (ROFR) that allows the company or existing investors to purchase the shares before they are sold to someone else.

Ignoring these requirements may create contractual problems and could prevent the transaction from moving forward.

Before discussing a secondary sale with a potential buyer, founders should understand exactly what their existing agreements require.

Timing Matters

Not every fundraising round is an appropriate time for founder liquidity.

Meaningful secondary transactions become more common around Series B or Series C, once the company has demonstrated stronger traction and investor demand has increased.

Earlier-stage investors often expect founders to remain heavily invested in the company’s future.

As the business matures, a carefully structured secondary sale may be viewed more favorably because it allows founders to reduce personal financial pressure while continuing to build the company.

Selling Too Much Can Send the Wrong Message

Investor perception matters. Founders commonly sell only about 5% to 10% of their holdings during a secondary transaction.

Selling a modest percentage may demonstrate that the founder remains committed to the company’s long-term success while gaining limited personal liquidity.

Selling a much larger portion of your ownership may cause investors to question your confidence in the business and could affect fundraising discussions.

Taxes Can Significantly Reduce Your Proceeds

The amount you receive at closing is rarely the amount you ultimately keep. Founder secondary sales may create:

• Capital gains tax.
• Possible effects on Qualified Small Business Stock (QSBS) treatment.
• A sale price that differs from the preferred share price negotiated in the financing round.

Understanding these issues before agreeing to a transaction helps founders evaluate the actual after-tax benefit rather than focusing only on the headline purchase price.

Discuss Founder Liquidity Early

Secondary sales often become part of broader fundraising discussions.

Rather than surprising investors late in the process, founders are generally in a stronger position when they raise the topic early with their lead investor.

Open discussions make it easier to understand:

• Whether investors support founder liquidity.
• How much of the founder’s ownership investors consider reasonable to sell.
• Whether any approvals will be required before closing.
• How the secondary sale fits into the overall financing structure.

Clear communication early in the fundraising process can reduce delays and avoid unnecessary misunderstandings.

Common Founder Mistakes

• Assuming founder shares can be sold without restrictions: Stockholder agreements frequently require board approval and may include a Right of First Refusal that limits who can purchase the shares.
• Selling too large a percentage of ownership: A modest secondary sale is often viewed differently from selling a substantial portion of your holdings, particularly during earlier financing rounds.
• Focusing only on the headline purchase price: Capital gains taxes, QSBS implications, and pricing differences between common and preferred shares may significantly affect the founder’s actual proceeds.
• Waiting until due diligence to mention the secondary sale: Discussing founder liquidity with key investors early in the fundraising process generally creates a smoother transaction.

10-Minute Founder Secondary Self Check

• Do my shareholder agreements allow me to transfer shares?
• Does my company have a Right of First Refusal?
• Is my fundraising round at a stage where founder liquidity is realistic?
• Am I selling only a reasonable percentage of my ownership?
• Have I calculated my after-tax proceeds?
• Have I reviewed whether the transaction affects my QSBS treatment?
• Have I discussed the proposed secondary sale with my lead investor?

If you cannot answer yes to all of these, you are not ready to sell founder shares yet.

Bottom Line

Founder secondary sales have become increasingly common as startups remain private for longer, but they require careful planning. Transfer restrictions, investor approvals, tax consequences, and fundraising dynamics all influence whether a secondary sale strengthens your financial position or creates unnecessary complications. Understanding these issues before negotiating a transaction allows founders to achieve personal liquidity while maintaining investor confidence.
