How to structure an investor-friendly secondary share sale

Secondary share sales, where existing shareholders sell their equity to new investors before an IPO or acquisition, are no longer a niche part of startup finance.

As private companies remain private for longer and traditional exits stretch out, secondaries are emerging as a core tool for liquidity and strategic alignment in the venture ecosystem.

Secondary transaction volumes surpassed $60 billion in global markets, driven by delayed IPO timelines and growing demand for liquidity before exit).

For founders and leadership teams, structuring a secondary sale is about unlocking cash in a way that keeps investors comfortable, preserves cap table stability, and reinforces trust, not undermining it.

In this article, you’ll learn how these sales work, what investors care about, how to time and structure them strategically, and how to communicate the transaction to keep investor confidence strong.

What is a secondary share sale?

A secondary share sale happens when an existing shareholder, typically a founder, early employee, or early investor, sells their existing shares to a new buyer without the company issuing new equity.

The company doesn’t receive fresh capital; instead, the seller converts existing equity into cash.

This distinguishes it from a primary funding round (where new shares are issued and capital flows into the business). A well-structured secondary sale can help employees realise value, allow founders to de-risk, and introduce new investors into the cap table without dilution.

Secondaries unlock liquidity without diluting existing shareholders, but they do change who owns the company.

Why investors care about how secondaries are structured

Investors are more open to secondary sales today than they were a decade ago. Historically, selling a large chunk of founder shares could be interpreted as a lack of confidence and jeopardise future rounds. (Some investors still view large founder sell-downs with caution, especially if not paired with a primary round).

That’s why how you approach the transaction, and how you structure and communicate it, matters.

What investors typically focus on includes:

• Timing relative to milestones. Investors prefer secondary transactions that align with key company achievements, such as a successful funding round, strong revenue traction, or product milestones, because they signal confidence and momentum, not desperation.
• Percentage sold. Small sell-downs (e.g., single digits of founder holdings) are usually interpreted as de-risking rather than cash-ing out. Large sell-downs early in a company’s life may raise questions about founders’ commitment.
• Buyer identity. Institutional secondary buyers or existing investors participating in a controlled way tend to inspire more confidence than unknown buyers, especially if the company’s governance already accommodates structured transfers.
• Consent and process. Most cap tables contain transfer restrictions, rights of first refusal (ROFR), and co-sale/right of tag-along clauses, which require company and investor approvals. Properly navigating these without surprises fosters trust.

Investors gauge secondary sales not just by whether they happen, but how they are executed.

When a secondary sale makes sense

Timing a secondary sale poorly can send the wrong signal, but done at the right point, it reinforces confidence.

Three scenarios where secondaries are generally appropriate:

1. Meaningful business milestones achieved. When the company hits significant revenue targets, lands key customers, or completes a strong capital raise, secondary liquidity can reinforce confidence rather than undermine it.
2. Late-stage lifecycle. Most founders consider secondary sales around Series C or later, or in the pre-IPO phase, when valuations are higher and the business is significantly de-risked.
3. Strategic retention needs. Allowing early employees to unlock incremental value can improve retention and morale without creating dilution.

Conversely, a secondary sale can be counterproductive when:

• It occurs too early or without significant strategic context
• It involves selling a large percentage of founder holdings without clear rationale
• It is executed without transparent communication to existing investors

Good timing and strategic alignment matter far more than speed or headline liquidity.

Core elements of an investor-friendly secondary structure

An investor-friendly secondary sale is one that’s transparent, orderly, and value-protective. Here’s how to think about the key components, explained with narrative context first and then summarised.

Company and investor consent

Most private companies have transfer restrictions and rights of first refusal (ROFR) in their articles or shareholder agreements.

These clauses allow the company (and sometimes existing investors) to buy shares first before they’re offered to outsiders.

Early engagement with the board and major investors to negotiate waivers or pre-approvals avoids last-minute friction.

Valuation and pricing

Unlike a primary round, secondaries don’t inherently set a new valuation for the company.

Pricing typically reflects recent financing round terms or agreed benchmarks, with discount considerations based on liquidity and buyer demand. Anchoring price discussions to credible and recent valuation metrics helps avoid signalling problems.

Alignment with primary rounds

Many investor-friendly secondaries are structured alongside a new funding round.

This provides a built-in valuation anchor and frames the secondary as part of overall momentum, not a separate cash-out event.

Documentation and legal compliance

Because secondaries involve transfers of ownership, they often trigger legal and tax considerations, such as 409A valuation impacts and tender-offer rules for larger transactions.

Consulting specialist counsel early reduces surprises and builds investor confidence.

Here’s a practical checklist to guide the process:

• Secure board and investor approvals early
• Tie secondary pricing to recent credible valuation benchmarks
• Consider pairing with a primary funding round
• Perform legal and tax compliance reviews
• Communicate clearly with all stakeholders

Structure and communication are as important as the economics of the sale itself.

Handling dilution and cap table impacts

One common concern with secondaries is how they interact with share dilution. While secondary sales don’t create new shares and therefore don’t dilute ownership, they can still impact the cap table in subtle ways.

For example, selling large blocks of shares to new investors can shift control dynamics and voting power, even if the overall share count doesn’t change. Understanding how changes in who owns the shares, not just how many, affects governance and future decisions is critical.

Because secondary buyers might expect certain rights (e.g., information rights or pro-rata participation in future rounds), structure these carefully so they don’t unsettle existing investors.

Communicating the sale to keep investors comfortable

Transparent and proactive communication matters. Investors want to understand:

• Why the sale is happening
• How much is being sold
• That the founder remains committed
• How pricing was determined

Framing the sale as a strategic liquidity event rather than a sign of checking out aligns incentives and preserves trust.

Industry advisors often recommend anchoring secondary sales around company milestones or existing financing conversations to signal confidence and continuity.

How you frame and communicate the sale can be as impactful as the sale itself.

Summary

A thoughtfully structured secondary share sale can be a powerful tool for founders, early investors, and employees.

It provides liquidity, rewards early stakeholders, and can deepen investor relationships when done with care. But missteps, particularly around timing, communication, and governance, can create confusion, erode confidence, or skew control dynamics.

Start with clarity on timing and purpose, align with strategic milestones where possible, secure necessary approvals early, and communicate openly with all shareholders. When you do this, a secondary sale becomes a confidence-building tool.

Secondary sales are a fantastic tool for turning equity into outcomes without rushing toward an IPO or raising money you don't need.

They give private companies a way to create liquidity for shareholders, reward long-term contributors, and bring fresh investors on board – all while maintaining a tight grip over the company's direction.
