Board seats, vetoes, drag-alongs and anti-dilution decide who holds power in a crisis

Control terms rarely matter when a company is thriving. They matter in down rounds, disputed sales and restructurings - exactly when founders and small investors most need to understand them.

The point

I think control terms are where small investors are most exposed and least informed. Nobody asks an angel's permission to add a veto or a full ratchet, but the angel lives with the consequences in the one scenario where they matter most. Reading these clauses at the time you invest is the only moment you can decide whether you are comfortable with them.

What is it?

Key control and protection terms:

Term What it does Board composition who sits on the board and who holds a majority Protective provisions require investor consent for specified actions Drag-along lets a majority force others to join a sale Tag-along lets minority holders join a sale on the same terms Anti-dilution adjusts investors' conversion price in a down round Founder vesting shares earned over time, reset or accelerated in some cases

Anti-dilution compared. An investor bought 1,000,000 preferred shares at 2.00 (2,000,000 invested). The company has 10,000,000 fully diluted shares. It then raises 3,000,000 at 1.00 per share, issuing 3,000,000 new shares.

Full ratchet: conversion price drops to 1.00 Investor converts into 2,000,000 / 1.00 = 2,000,000 shares

Broad-based weighted average: New price = 2.00 x (10,000,000 + 3,000,000 / 2.00) / (10,000,000 + 3,000,000) = 2.00 x 11,500,000 / 13,000,000 = about 1.7692 Investor converts into 2,000,000 / 1.7692 = about 1,130,435 shares

Full ratchet gives the investor about 869,565 more shares than the weighted average version, all of them diluting founders and other common holders.

A drag-along can force a small holder to accept a sale they oppose, if the required majority approves. A tag-along protects a small holder from being left behind when a majority sells.

Why does an investor care?

Because these terms are dormant when things go well and decisive when they do not. A board majority can replace a CEO. Protective provisions can block a rescue financing. A full ratchet can transfer a large share of the company in a down round.

Small investors rarely negotiate these terms but are bound by them, so understanding them is part of knowing what you own.

Educational, not personalised financial advice. Nothing in the Investor Academy is a recommendation to buy, sell or hold anything — what is right for you depends on your own circumstances and the rules where you live.

Example

A down round with full ratchet protection. Continuing the example, before the new round the investor's 1,000,000 shares were 10% of 10,000,000.

Full ratchet: 2,000,000 shares of 14,000,000 total (10,000,000 existing + 1,000,000 ratchet adjustment + 3,000,000 new) = about 14.3% Weighted average: about 1,130,435 of about 13,130,435 = about 8.6%

Under full ratchet, the earlier investor's share rises despite the company doing worse, and common holders absorb both the new round and the ratchet adjustment.

The common mistake

Ignoring control and anti-dilution terms because they seem unlikely to matter. They are designed for bad outcomes, which are common in early-stage investing.

How it works

Step 1: Map the board

Count seats by group and identify who controls a majority now and after likely future rounds.

Step 2: List the protective provisions

Note every action requiring investor consent and whether it could block a needed financing or sale.

Step 3: Identify anti-dilution type

Check whether it is full ratchet or weighted average, and compute its effect in a hypothetical down round.

Step 4: Read drag-along thresholds

Find what majority can force a sale and whether minimum price or other protections apply to minority holders.

When to use this

When joining a round, evaluating an existing stake, or when a company faces a down round or sale.

When not to use it

Do not assume standard terms apply. Always read the actual documents, since protections vary and can be modified by later rounds.

How investors actually did it

A recurring pattern: weighted average as the market norm

Surveys of venture financing terms published by law firms have consistently reported broad-based weighted average anti-dilution as the most common form in venture rounds, with full ratchet provisions relatively rare and more frequent in difficult funding environments.

A full ratchet is a departure from common practice. Treat it as a significant term worth understanding before investing.

Do this now

  • Check whether a company you hold has full ratchet or weighted average anti-dilution
  • Find the majority required for a drag-along

  • A term sheet sets two things: who gets the money and who gets the say — Every clause in a term sheet affects either the economics - how proceeds are divided - or control - who can make or block decisions. Valuation is only one economic term among several. (10 min)
  • A smaller slice of a much bigger company is usually the good outcome — Each funding round reduces existing holders' percentage. Dilution is not a loss in itself; it becomes one when the company's value does not rise enough to compensate, as in a down round. (12 min)
