Startup Secondary Transactions: Founder & Employee

How to run a secondary transaction to give founders and employees liquidity in 2026.

How to Run a Secondary Transaction for Your Startup

Secondary transactions — founder + employee liquidity in private companies before IPO — became structurally important in 2023-2026 as median time-to-IPO extended to 10+ years (from ~6-7 years in 2010s). Buyers include dedicated secondary funds (StepStone, Industry Ventures, Greenspring / StepStone, HarbourVest, Coller Capital, Lexington Partners, Ardian, Portfolio Advisors, Committed Advisors), platforms (Forge Global public, EquityZen, Hiive, Nasdaq Private Market, CartaX / wound-down 2023, Setter Capital), plus growth funds running direct secondaries (Sequoia Capital Fund, General Catalyst continuation, Tiger Global secondary, Coatue direct-secondary, Greenoaks, Iconiq, Franklin Templeton, T. Rowe Price, Fidelity, BlackRock).

Why secondaries matter more in 2026

Median time-to-IPO has extended to 10+ years (from ~6-7 years in 2010s). 2022-2024 IPO window largely closed for venture-backed companies (materially fewer IPOs than 2020-2021 peak). Employees face 10-year ISO exercise windows expiring, RSU double-trigger vesting cliffs, and life-event liquidity needs. Founders face dilution + concentration risk with 90%+ net worth in illiquid equity. Secondary transactions provide interim liquidity while allowing companies to stay private longer. Common secondary types include company-run tender offers (all-employee, priced by third-party 409A + negotiated with buyer), direct secondaries (specific holder to specific buyer, often as part of primary round), warehousing (buyer acquires and holds pending liquidity), and structured deals (preferred conversion, participation, ratchets).

The most active secondary buyers in 2026

Dedicated secondary funds: StepStone (acquired Greenspring 2021 — largest venture secondary buyer, $60B+ AUM), Industry Ventures (dedicated venture secondary since 2000, multiple fund vintages), HarbourVest, Coller Capital, Lexington Partners (Franklin Templeton subsidiary), Ardian (French PE + secondary), Portfolio Advisors (StepStone subsidiary), Committed Advisors, Whitehorse Liquidity Partners (structured secondaries), Kline Hill Partners, Pomona Capital, plus AlpInvest / Carlyle (secondary + primary hybrid).

Platform secondaries: Forge Global (public — merged with SPAC 2022, has consolidated the SharesPost + Forge marketplace), EquityZen (accredited investor platform), Hiive (post-2022 platform focused on well-known unicorns with active bid-ask), Nasdaq Private Market (institutional tender offers), Setter Capital, plus Carta CartaX shut down 2023 (Carta focused on cap table + valuation services after CartaX wound down amid customer data-use controversy).

Direct-secondary growth funds: Sequoia (Sequoia Capital Fund evergreen structure allows crossover primary + secondary), General Catalyst (multiple continuation vehicles + direct secondary), Tiger Global (secondary-heavy 2021-2022 rounds, materially rationalized 2023-2024), Coatue (direct secondary in AI + growth names), Greenoaks (direct secondary in specific names), Iconiq (direct secondary in specific names), plus mutual funds (Fidelity, T. Rowe Price, BlackRock, Franklin Templeton) with private-company holdings taking direct secondary positions.

Tender-offer-specific: Manhattan Venture Partners, SharesPost / Forge, plus tender-specific arrangements with StepStone / Industry Ventures / HarbourVest as anchor buyers for company-sponsored tenders.

Secondary transaction types

Company-run tender offer: Company sponsors an all-employee liquidity event, typically at a discount to the most recent primary round 409A (5-25% discount common — reflects illiquidity + secondary preferred/common structure). Company selects anchor buyer(s), negotiates price + terms, files SEC tender offer materials, employees elect participation within window (typically 20 business days), buyer purchases shares from participating employees.

Direct secondary: Specific holder (founder, early employee, angel investor, seed VC) sells to specific buyer, typically as part of primary round or standalone. Company + preferred holders often have ROFR (right of first refusal) + co-sale rights that must be waived or exercised. Board approval typically required.

Warehousing: Buyer acquires shares and holds pending future liquidity (IPO, acquisition, subsequent secondary). Common for hard-to-source names.

Structured secondary: Preferred conversion, participation caps, ratchets, or other structure to enable buyer to underwrite while accommodating company + seller constraints.

Tax reality — 409A, RSU, ISO, QSBS Section 1202

409A valuation: Governs the strike price of options and the tax-recognized value of vested RSUs. Third-party 409A valuations (Aranca, Carta, Scalar, Value Scope, Solium) are typically updated annually or after material events. Secondary transactions above 409A can trigger 409A revaluation.

ISO (Incentive Stock Options): Long-term capital gains treatment if held 2+ years from grant and 1+ year from exercise. AMT (Alternative Minimum Tax) exposure on exercise. 10-year post-termination exercise window (Section 422 requires exercise within 90 days of termination for ISO treatment, though many companies extend to 10 years for NSO treatment). Selling ISO shares in secondary triggers capital gains (long-term if holding period met, short-term otherwise).

NSO (Non-Qualified Stock Options): Ordinary income at exercise on spread (FMV - strike), capital gains on subsequent appreciation. No holding period restriction for exercise.

RSU (Restricted Stock Units): Ordinary income + payroll tax at vest (double-trigger commonly requires IPO or acquisition liquidity to actually vest). Selling vested RSU in secondary triggers short-term (if less than 1 year from vest) or long-term (if more than 1 year) capital gains.

QSBS Section 1202: Federal tax exclusion up to $10M or 10x basis (whichever greater) per shareholder per issuer for qualified small business stock (C-corp, less than $50M gross assets at issuance, active business) held 5+ years. State treatment varies (California + Pennsylvania don't conform, New Jersey partial). Section 1202 is one of the most valuable tax benefits available to founders and early employees — plan secondary sales to maximize QSBS treatment (partial sales, spousal stacking, gifting).

Common mistakes when running a secondary

Running a tender offer without SEC compliance (Rule 13e-4 issuer tender rules for reporting companies, Rule 14e for non-reporting — 20 business day window, equal treatment, disclosure obligations). Setting the tender price too close to primary round 409A (secondary buyers require illiquidity discount — 5-25% typical). Not addressing 409A revaluation implications (tender above 409A can trigger revaluation and impact option strike prices for future grants). Failing to plan QSBS Section 1202 sequencing (5-year holding period, $10M or 10x basis exclusion — partial sales + spousal stacking can multiply). Ignoring board + preferred ROFR + co-sale rights on direct secondaries. Not disclosing all material information to tender participants (creates litigation risk). Confusing warehousing with genuine secondary (warehousing creates buyer overhang for future liquidity).

What are the main startup secondary transaction types?
Company-run tender offer sponsors an all-employee liquidity event, typically priced at a 5-25% discount to the most recent primary round 409A (reflects illiquidity plus secondary preferred / common structure). The company selects anchor buyer(s), negotiates price and terms, files SEC tender offer materials, and employees elect participation within a window (typically 20 business days). Direct secondary is a specific holder (founder, early employee, angel investor, seed VC) selling to a specific buyer, typically as part of a primary round or standalone — the company plus preferred holders often have ROFR (right of first refusal) plus co-sale rights that must be waived or exercised, and board approval is typically required. Warehousing is when a buyer acquires shares and holds pending future liquidity (IPO, acquisition, subsequent secondary) — common for hard-to-source names. Structured secondary uses preferred conversion, participation caps, ratchets, or other structure to enable the buyer to underwrite while accommodating company and seller constraints.
What tax rules matter most for founder and employee secondary sales?
409A valuation governs the strike price of options and the tax-recognized value of vested RSUs, and secondary transactions above 409A can trigger 409A revaluation. ISO (Incentive Stock Options) receive long-term capital gains treatment if held 2+ years from grant and 1+ year from exercise, with AMT exposure on exercise. NSO (Non-Qualified Stock Options) trigger ordinary income at exercise on the spread (FMV minus strike), with capital gains on subsequent appreciation. RSU (Restricted Stock Units) trigger ordinary income plus payroll tax at vest (double-trigger commonly requires IPO or acquisition to actually vest). QSBS Section 1202 provides federal tax exclusion up to $10M or 10x basis (whichever greater) per shareholder per issuer for qualified small business stock (C-corp, less than $50M gross assets at issuance, active business) held 5+ years — state treatment varies (California and Pennsylvania don't conform, New Jersey partial). Partial sales, spousal stacking ($10M per spouse), and gifting to family members can multiply the QSBS benefit. Consult tax counsel before running secondary.
How should founders price a tender offer relative to the primary round 409A?
Secondary pricing is typically at a 5-25% discount to the most recent primary round 409A, which reflects illiquidity plus secondary preferred / common structure. Well-known unicorns with active bid-ask on Hiive / EquityZen may trade closer to or above 409A. Pre-IPO companies with visible IPO timeline may trade at a premium to prior primary. Companies with valuation reset exposure (2021-2022 peak rounds) may trade at a material discount. Get third-party price validation from multiple buyers before committing. Also consider 409A revaluation implications: a tender above 409A can trigger 409A revaluation (typically upward), which impacts option strike prices for future grants (higher strike equals less employee wealth creation per option). Some companies structure tenders at or below 409A to avoid revaluation; others accept revaluation and communicate transparently.
What is the typical timeline for a company-sponsored tender offer?
A tender offer typically runs 8-12 weeks. Weeks 1-4: anchor buyer(s) selection plus preliminary pricing negotiation. Weeks 4-6: 409A valuation update plus tender materials preparation (including comprehensive disclosure of 409A methodology, material adverse changes, use of proceeds, and financial condition). Week 6: SEC plus Blue Sky filings (Rule 13e-4 issuer tender for reporting companies, Rule 14e for non-reporting). Weeks 6-10: 20 business day tender offer window during which employees elect participation. Weeks 10-12: settlement plus proceeds distribution. Direct secondary transactions typically run shorter (4-8 weeks): buyer identification plus preliminary pricing (weeks 1-2), ROFR plus co-sale plus board approval (weeks 2-4), definitive documents plus closing (weeks 4-8). Communicate transparently with employees and shareholders throughout.
