Seed-stage shareholders’ agreements: key clauses founders should know

Why shareholders’ agreements matter more at seed than at pre-seed

At pre-seed, shder agreements are often light. The company is small, trust is high, and expectations are informal. Seed changes the game. More capital enters. New investors join the cap table. The company starts to scale. From that point on, ambiguity becomes expensive.

The shareholders’ agreement is where trust is translated into enforceable rules. Founders who treat it as “standard paperwork” usually regret it later not because clauses are abusive, but because their implications were misunderstood.

Governance: control, balance, and trust

Governance is not just about formal power. It defines how decisions are made when pressure increases.

Board composition: what works in practice

At seed stage in Europe, the most effective boards usually have 3 to 5 members:

• 3 members: typically two founders and one investor
• 5 members: founders, lead investor, and possibly one independent or observer

Larger boards slow execution. Smaller boards lack balance.

Best practices:

• Founders retain operational control
• Investors gain oversight, not management authority
• Independent board members are rarely mandatory at seed

Good governance is not about control. It is about decision quality.

Reserved matters: where power really sits

Reserved matters define decisions that require investor consent. This section has more impact on daily life than many founders expect.

Typical seed-stage reserved matters include:

• Issuing new shares or modifying share capital
• Significant acquisitions or asset disposals
• Changes to business scope
• Executive compensation and key strategic hires
• Amendments to governance documents
• Liquidity as a reserved matter (often overlooked)

In Europe, it is increasingly common to include a liquidity clause as a reserved matter.

Usually framed around:

• A 5 to 10 year horizon
• An obligation to initiate or consider a liquidity process
• Not a forced sale, but a structured discussion

This protects investors from permanent illiquidity while preserving founder flexibility. Founders should ensure the clause encourages a process, not an automatic outcome.

Founder lock-up and leaver clauses

Seed investors invest in teams. Founder commitment is therefore central.

Lock-up

Founders are typically restricted from selling shares for several years. This is standard and rarely negotiable.

Good leaver / bad leaver

The distinction matters more than the label.

Founders should carefully review:

• What qualifies as a good leaver (health, mutual agreement, investor-led removal,…)
• What triggers bad leaver treatment
• How shares are valued in each case

Unclear leaver clauses are one of the most common sources of future conflict.

Preferred shares: understanding the mechanism

Seed investors in Europe usually invest through preferred shares.

What preferred shares actually do

Preferred shares grant investors specific rights, typically:

• Economic preference (through liquidation preference)
• Certain governance protections
• Enhanced information rights

They do not grant day-to-day control.

Liquidation preference (high level)

At seed stage in Europe:

• 1x non-participating liquidation preference is standard
  Investors recover their investment first, then remaining proceeds are shared pro rata

Complex preference structures at seed are uncommon and should raise questions.

Anti-dilution: more than just down-round protection

Anti-dilution clauses are often reduced to “down-round protection.” This is incomplete.

Their broader purpose is to allow investors to maintain a minimum level of ownership when value creation underperforms expectations typically, but not exclusively, in down-round scenarios.

At seed stage in Europe:

• Anti-dilution clauses are generally moderate
• Full ratchet mechanisms are rare
• Broad-based weighted average structures are more common

Founders should focus less on formulas and more on intent:

• Does the clause apply only in real value-destructive situations?
• Is it proportionate?
• Does it preserve long-term alignment?

Protection is legitimate. Punitive mechanics are not.

Transfer restrictions and liquidity mechanics

Seed-stage agreements strongly limit share transfers. This is normal and healthy.

Common clauses include:

• Pre-emption rights
• Approval rights
• Tag-along and drag-along clauses

These mechanisms protect fairness and cap table stability. Founders should ensure they understand how liquidity is expected to happen, not just that it might happen one day.

Information and reporting rights

Reporting obligations formalise trust.

Typical expectations at seed include:

• Regular financial reporting
• Budget and cash runway visibility
• Strategic updates

These clauses rarely become problematic when communication is clear. Most investor tensions arise from lack of information, not from over-reporting.

What is usually negotiable — and what rarely is

Often negotiable:

• Scope of reserved matters
• Board composition and observer rights
• Reporting frequency

Rarely negotiable:

• Preferred share structure
• Core investor protections
• Transfer restrictions

Effective negotiation is selective. It focuses on what will matter three to five years later.

Founder takeaway

Before signing a seed-stage shareholders’ agreement, founders should remember:

• Seed legal terms shape daily governance, not just exits
• Preferred shares and anti-dilution clauses are about alignment, not control
• Liquidity clauses define expectations long before they are triggered
• Legal clarity early prevents conflict later

Fundraising is only a means. As we explain in What it really takes to raise a pre-seed or seed round in France & Europe, strong companies are built through clarity, discipline, and alignment including legal alignment.

At seed stage, the shareholders’ agreement is not a constraint. It is part of building the company.
