Secondary Sales for Founders — When and How to Take Money Off the Table
A practical guide for startup founders considering selling some of their equity in a secondary transaction. Covers timing, mechanics, tax implications, and common mistakes.
Secondary Sales for Founders — When and How to Take Money Off the Table
You've been grinding for years. Ramen-profitable turned into real revenue. You just closed your Series B. Your equity is worth something real on paper — but your bank account still looks like it did in year one.
At some point, every founder asks the question: Can I sell some of my shares?
The answer is yes. But the how and when matter enormously. Get it wrong and you can blow up investor relationships, trigger tax disasters, or violate your own company's agreements. Get it right and you take some well-deserved risk off the table while keeping everyone aligned.
I've helped dozens of founders navigate secondary sales. Here's what you need to know.
What Is a Secondary Sale?
A secondary sale is when an existing shareholder — you, the founder — sells some of their shares to another party. Unlike a primary fundraise where the company issues new shares and receives the proceeds, in a secondary transaction the money goes directly to you.
The buyer is typically one of three parties:
- An existing investor who wants to increase their ownership
- A new investor coming into a funding round who buys some shares from founders alongside the primary investment
- A secondary fund or marketplace that specializes in buying pre-IPO equity
The company doesn't receive any capital from a secondary sale. That's the key distinction and one reason investors pay attention to how much founders are selling.
When Founders Typically Sell
The realistic window for most founder secondaries opens at Series B or later. Here's why:
- Pre-Series A / Seed: Almost never appropriate. You're still proving the business works. Selling equity at this stage sends a terrible signal and most investors would view it as a red flag.
- Series A: Rare, but occasionally a small amount ($100K–$250K) gets negotiated into the round. It's becoming more accepted, but don't push it.
- Series B+: This is the sweet spot. The business has real traction, the valuation is meaningful, and investors generally understand that a founder who's been at it for 5+ years deserves some liquidity.
- Series C and beyond / Pre-IPO: Very common. At this stage, secondary sales are often formalized through structured tender offers.
The general principle: the more proven the business, the more acceptable the secondary.
Tender Offers vs. Direct Sales
There are two primary mechanisms for founder liquidity:
Tender Offers
A tender offer is a structured, company-sponsored process where eligible shareholders (founders, early employees, sometimes all shareholders) can sell a portion of their shares. These are typically organized alongside or between funding rounds.
Tender offers are cleaner because:
- The company controls the process
- Pricing is standardized (usually at the last round's price or a slight discount)
- Legal and compliance work is handled centrally
- Everyone gets the same terms
If your company is running a tender offer, participate. It's the path of least resistance.
Direct Sales
A direct sale is when you independently find a buyer and negotiate a transaction. This is messier:
- You need to find a willing buyer
- You'll need company cooperation (more on transfer restrictions below)
- Pricing is negotiated bilaterally
- Legal costs are on you
Direct sales work but require more effort and more care around compliance with your company's governing documents.
Transfer Restrictions: The Stuff That Can Kill Your Deal
Before you sell a single share, you need to read three documents:
1. Your Stockholders' Agreement (or Investors' Rights Agreement)
Almost every venture-backed company has one. It almost certainly contains:
- Right of First Refusal (ROFR): The company and/or existing investors have the right to purchase your shares at the same price and terms before you can sell to a third party. This means if you find a buyer at $50/share, the company or investors can step in and buy those shares instead.
- Co-Sale Rights (Tag-Along): If you sell shares, other shareholders (usually investors) may have the right to sell a proportional amount of their shares in the same transaction, on the same terms.
Both of these require you to give proper notice before completing any sale. Skip this step and the transfer may be void — or worse, you've breached your agreements.
2. Your Company's Bylaws and Certificate of Incorporation
These may contain additional transfer restrictions, including board approval requirements for any share transfers.
3. Any Lock-Up or Restriction Agreements
If you signed anything at the last funding round restricting sales for a period of time, that matters too.
The bottom line: You cannot just sell your shares to whoever you want, whenever you want. Your company's documents almost certainly require notice, board consent, and compliance with ROFR/co-sale provisions. Work with counsel to navigate this before you have a buyer lined up.
How Much Is Reasonable?
The unwritten rule: 10–20% of your holdings is generally considered acceptable in a single secondary transaction.
Sell 5–10%? Nobody blinks. Sell 15–20%? Probably fine at Series B+, especially if the business is performing well. Sell 40%? You're going to have a very uncomfortable board conversation.
The reason is alignment. Investors want founders who have significant skin in the game. If you sell so much that your remaining equity doesn't motivate you to push for a massive outcome, you've undermined the entire incentive structure that venture capital is built on.
A few guidelines:
- Keep the bulk of your equity intact. Your biggest payday should still be at exit.
- Don't sell more than your lead investor is comfortable with. Have the conversation before you start the process.
- Consider selling in stages. A small secondary at Series B, another at Series C, etc. This is more palatable than one large sale.
Investor Attitudes: The Stigma Is Fading (But Not Gone)
Five years ago, many VCs viewed founder secondaries as a sign of wavering commitment. That attitude has shifted significantly.
Today, most sophisticated investors recognize that:
- Founders who've been building for 5–7 years have made enormous personal financial sacrifices
- A founder who takes some risk off the table is often more focused, not less — financial stress is distracting
- The alternative is founders who burn out or make conservative decisions because they can't afford to take risks with the company
That said, norms still exist:
- Don't bring it up in your first meeting with a new investor. Let them bring it up, or raise it late in the process after terms are largely agreed.
- Frame it correctly. "I'd like to take a small amount of secondary" is fine. "I need to cash out" is not.
- Be transparent. Trying to do a secondary behind your board's back is a relationship-ender.
- Performance matters. If the company is crushing it, nobody cares about a 10% secondary. If you're missing targets, even 5% looks bad.
The best founders I work with treat secondaries as a normal part of the conversation, not something to be ashamed of. The investors worth working with feel the same way.
Tax Considerations: Don't Leave Money on the Table (or Give It to the IRS)
This is where founders most often screw up. A secondary sale is a taxable event, and the tax treatment depends on several factors:
Long-Term vs. Short-Term Capital Gains
If you've held your shares for more than one year, you'll pay long-term capital gains rates (currently 20% federal + 3.8% NIIT for high earners). If you've held for less than a year, you're paying ordinary income rates — potentially 37%+ federal.
Make sure your shares have been held long enough. If you exercised options recently, count from the exercise date, not the grant date.
QSBS: The Big One
Section 1202 Qualified Small Business Stock (QSBS) exclusion can allow you to exclude up to $10 million (or 10x your basis, whichever is greater) in capital gains from federal tax. This is potentially the single most valuable tax benefit available to founders.
But here's the catch: QSBS requires a 5-year holding period. If you sell shares before you've held them for five years, you lose the exclusion on those shares entirely.
I've seen founders leave millions on the table by doing a secondary six months before they would have qualified for QSBS. Do the math. If waiting gets you a tax-free sale, it's almost always worth it.
Other QSBS considerations for secondary sales:
- The shares must have been acquired at original issuance (not purchased on the secondary market)
- The company must be a qualified C corporation with aggregate gross assets under $50M at the time of issuance
- Certain share transfers can disqualify QSBS eligibility — get specific advice here
State Taxes
Don't forget state income tax. If you're in California, you're paying an additional 13.3% on the gain regardless of federal treatment. Some founders have timed moves to no-income-tax states before large liquidity events. That's a separate conversation, but it's worth having.
Board and Investor Approval Mechanics
The typical process for a founder secondary:
- Inform your lead investor and board informally. Get a temperature check before formalizing anything.
- Identify the buyer and agree on terms. Price, quantity, any conditions.
- Deliver formal ROFR/co-sale notice per your stockholders' agreement.
- Wait the notice period (usually 30 days) for the company or investors to exercise their rights.
- Obtain board approval if required by your governing documents.
- Execute the purchase agreement and transfer shares.
- Update the cap table and company records.
Do not skip steps. Do not try to shortcut the process. I've seen deals blow up because a founder sold shares without proper notice and the company treated the transfer as void.
Common Mistakes
After years of advising on these transactions, here are the mistakes I see most often:
- Selling too early. A secondary at seed stage signals you don't believe in the company. Wait until the business supports it.
- Not checking transfer restrictions. Your stockholders' agreement has ROFR, co-sale, and board consent provisions. Ignoring them can void the transfer.
- Blowing your QSBS eligibility. Selling before the five-year hold is one of the most expensive tax mistakes a founder can make. Run the numbers.
- Not getting proper board consent. Even if your docs don't explicitly require it, surprising your board with a secondary sale is a trust-destroying move.
- Selling too much. Taking 30%+ off the table signals misalignment. Keep the bulk of your equity intact.
- Poor timing. Don't try to do a secondary when the company is struggling or during sensitive negotiations. Read the room.
- Using the wrong counsel. Your company's lawyers represent the company, not you personally. Get your own startup-savvy attorney for secondary transactions.
The Bottom Line
Secondary sales are a normal, healthy part of the startup lifecycle. If you've been building for years and the company is performing well, you've earned the right to take some chips off the table.
But do it right. Check your agreements, talk to your board, understand the tax implications, and keep the amount reasonable. The goal is to reduce your personal financial risk without undermining the alignment that makes the whole venture model work.
