The People Running Duolingo

Governance grade: B. Real-money skin in the game, a credibly independent board (7 of 9), and a CEO whose total cash pay is $767,500 — about the same as the median employee multiplied by 2.6. The only structural weakness is a dual-class share structure that hands the two co-founders ~76% of the vote while owning roughly 14% of the economic equity. That mismatch is the one fact that decides whether you trust this company.

1. The People Running This Company

Duolingo is run by the two PhDs who founded it in 2011, plus a small, technically deep operating team. The slate matters because (a) the co-founders still control the vote, and (b) the CFO seat just turned over for the first time in years.

Luis von Ahn's reputational risk is not corporate misconduct — it is judgment. His April 2025 internal "AI-first" memo (gate hiring on automation, evaluate employees on AI usage, phase out contractors) leaked publicly, triggered a backlash, and was walked back twice — once in an August 2025 NYT interview ("We've never laid off any full-time employees… This was on me") and again in April 2026 when AI-tied performance reviews were reversed. The pattern: bold internal calls, then public retreat. Operating execution has not yet been affected, but it is a data point on crisis judgment.

2. What They Get Paid

The CEO is paid like a cap-table consultant, not a Fortune 500 chief. Von Ahn has taken $750K base + zero new equity every year since the 2021 IPO. His total comp ($767,500) is 2.6× the median Duolingo employee — extraordinarily low; most large-cap US CEOs run 200×–800×. His upside is locked in the 2021 founder PSU award: 1,200,000 PSUs (600,000 for Hacker) with a 10-year life and ten price hurdles tied to multiples of the $102 IPO price. As of December 31, 2025, eight of ten tranches had vested. With the stock at $175.50 at year-end (and meaningfully lower after the February 2026 sell-off), the two remaining hurdles look further away. Net effect: the founders' incremental incentive after this award largely depends on existing share value, not new grants.

For non-founder NEOs, pay is structured cleanly: small salary, large time-vested RSUs over four years, no cash bonus plan, no options, no perks. Total NEO pay ($5.4M for the CFO and CEO of Engineering each) is in line with Duolingo's $1.04B revenue and Bumble/Pinterest/Match-Group peer group. Say-on-pay passed in June 2025 with ~98.8% support — a confidence signal from public shareholders, who collectively hold roughly 24% of the vote.

The chart above tells the cleaner story than the summary table. CEO reported pay (gray line) has been flat at ~$767K since 2022; "compensation actually paid" (blue, SEC mark-to-market) swings from +$140M in 2023 to −$44M in 2025 purely because of PSU revaluation. The pay-for-performance link is real — it just sits in the founder PSU, not in annual grants.

3. Are They Aligned?

This is where Duolingo deviates most from peer governance norms. Insider economic ownership is among the strongest in the sector; voting alignment is among the weakest.

Each Class B share carries 20 votes; Class A carries 1. The two co-founders own 6.18M Class B shares and effectively vote 76% of the company despite owning roughly 14% of the cash flows. Public shareholders — including some of the most sophisticated institutions in the world (Baillie Gifford, BlackRock, Capital World) — collectively own ~78% of the economics and ~8% of the vote. There is no sunset clause on the dual-class structure in the filings.

Insider trading: founders take divergent paths

Three signals in this chart:

1. Von Ahn has not sold a single open-market share. His only 2025–2026 disposition was a 1,000-share gift to the von Ahn Foundation. His ~$588M economic stake remains intact.
2. CTO Hacker sold heavily — ~$19.8M across eight planned tranches between August and November 2025, finishing before the February 26, 2026 earnings call that took the stock down 23%. All sales were under a 10b5-1 plan adopted September 2024, and a Schedule 13G/A in April 2025 had already disclosed a ~12% cut in his beneficial stake. Pre-planned does not mean uninformed — the timing pattern is worth a footnote even if it is procedurally clean.
3. Director Jim Shelton bought 5,000 shares at $99.76 (~$499K) on March 3, 2026 — the only insider open-market purchase in the dataset, made a week after the crash. The signal is small in dollars but valuable in conviction.

Founder PSU vesting — the alignment scoreboard

Eight of ten founder PSU price hurdles have been satisfied. The structural alignment benefit of this award is largely behind shareholders, not in front of them. After 2031, the founders would need a new equity contract for the company to recreate today's pay-for-performance tightness; the board has signaled the PSUs were intended as exclusive equity for the co-founders through the tenth IPO anniversary, so any post-2031 grant will be a fresh negotiation worth watching.

Capital allocation, dilution, related parties

Share count discipline is unremarkable for a young SaaS. The 2021 equity plan provides for an annual increase of up to 5% of common stock outstanding; the board waived the corresponding ESPP increase for 2026, signaling restraint. SBC runs high in absolute dollars but is concentrated in time-vested RSUs to non-founders. No buyback. No dividends. No warrants. No executive has pledged any stock, and hedging by insiders is prohibited.

Related-party transactions are limited to standard indemnification agreements; there are no disclosed material related-party deals above the $120K Item 404(a) threshold. The audit committee approves any future ones in advance. The single related-party-adjacent fact worth flagging is the director-to-CFO Munson move — disclosed and lawful, but it reduces the number of independent directors who can challenge management on accounting matters until a replacement audit-committee member is named.

Skin-in-the-game score

9 out of 10. Founders hold ~$1.1B of stock between them at the December 31, 2025 closing price; the CEO has never sold a share outside a foundation gift; hedging is banned and no pledging exists. The one point withheld reflects (a) Hacker's aggressive 2025 selling cadence and (b) the fact that the founder PSU — Duolingo's flagship alignment vehicle — is already 80% earned.

4. Board Quality

Nine directors, seven independent under Nasdaq rules. Three classes of directors with staggered three-year terms (an entrenchment defense that requires three years to flip the board). Four standing committees — Audit, Compensation, Nominating & Governance, and an M&A Committee — each chaired by an independent director. The audit committee chair (Sara Clemens) is the designated audit committee financial expert.

Board expertise scorecard

What this board is great at: consumer technology, product, content/games. Bohutinsky (Zillow COO), Clemens (Twitch/Pandora COO), Gordon (Electronic Arts) and Ross (Microsoft/Halo) collectively understand how a freemium consumer brand scales and monetizes. Schlosser adds founder-CEO operating perspective from Oscar Health.

What this board is light on: deep finance and risk/audit talent. Sara Clemens carries the entire audit-committee-financial-expert load. Munson, the prior audit chair, has just moved to CFO. The next director hire should be a sitting CFO or an experienced public-company audit committee chair from outside consumer/gaming. Otherwise, the audit and risk function is structurally thinner than the company's $400M+ in annual booking volume warrants.

Compliance lapses

Board attendance was above 75% for every director in 2025. No Section 16 settlements, no SEC actions, no shareholder lawsuits had been filed at the time of the proxy (April 2026); two plaintiffs' firms (Faruqi & Faruqi, Johnson Fistel) have publicly solicited claims after the February 2026 stock drop, but no complaint has been filed and the cause cited is operating disclosure, not governance misconduct.

5. The Verdict

Grade: B. Duolingo earns a clean B on the substance of governance: a founder-CEO with ~$590M of personal economic stake who has not sold an open-market share, a CEO pay ratio of 2.6:1 that is among the lowest in US large-cap tech, a fully time-vested RSU structure for non-founders, a 7-of-9 independent board with a credible committee structure, prohibited hedging, no pledging, and a clean related-party record. The single fact that holds the grade below A is the dual-class structure: the two co-founders control 76% of the vote on 14% of the economics, the structure has no sunset, and the staggered board would take three years to flip even if outside shareholders organized.

Most likely to drive an upgrade: (a) introduction of a sunset on the high-vote Class B (rare in founder-led tech, but Lyft and Pinterest have both made gestures), (b) hire of an independent CFO-quality audit committee chair to backfill Munson, and (c) a renewed founder PSU on terms that re-engage long-dated alignment after tranche 10 lapses or is hit.

Most likely to drive a downgrade: (a) any acceleration of CTO Hacker's selling pace beyond the existing 10b5-1 plan, (b) a related-party transaction involving the von Ahn Foundation or any founder-affiliated entity, (c) a CEO recanting cycle of the same pattern as the 2024–2026 AI / contractor episode but on a topic that materially hits financials, or (d) say-on-pay support falling below 90%.

The one thing to monitor: whether the next director added to the audit committee is genuinely independent and finance-deep, or just another consumer-tech operator. That single appointment will tell investors whether the board is willing to strengthen its own oversight muscle, or whether the founder-control culture is hardening into something that will eventually be priced as a discount.
