Pre-seed: what founders really need to prepare

Updated March 2026 - Pre-seed is often presented as a vague seed phase, reserved for startups at the very beginning of their journey. In practice, this is a very demanding step. At this stage, the challenge is not only to convince an investor. It is necessary to show that there is a market thesis, an execution capacity, a first level of traction or validation, and a credible use of funds. The pre-seed is not a pitch competition. It is a construction exercise.

In summary: pre-seed financing is the first round of financing for a startup, occurring before the seed. In France, the amounts are generally between 100,000 and 500,000 euros.

What is pre-seed and how does it differ from seed?

Pre-seed financing is located chronologically and strategically between personal seed funding (love money, founder savings) and the institutional seed round. The distinction is not just a question of amount: it concerns the level of maturity of the project.

CriteriaPre-seedSeed
Project stageIdea, prototype, MVPValid product, first customers
Typical amount France100,000 to 500,000 euros500,000 to 3 million euros

Main objectiveValidate the problem and the productValidate the model and accelerate growth
Expected dilution5 to 15%15 to 25%
Cash flow horizon12 to 18 months18 to 24 months

In 2026, the border between pre-seed and seed is clarified. Funds now require stronger traction signals, making pre-seed even more strategic.

What is the average pre-seed amount in France and Europe?

The pre-seed amount varies considerably depending on geography, sector and the profile of the founding team.

In France

The pre-seed startup France is between 100,000 and 500,000 euros. Deep tech projects can exceed this ceiling.

In Europe

Amounts range from 100,000 to 1 million euros, with major centers in London, Berlin and Paris. France has established itself as a major ecosystem thanks to the French Tech network and Bpifrance.

In the United States

The American market displays higher amounts, up to $2 million for projects with high potential.

Hayot Expertise Advice: pre-seed is not an end in itself. It is a way to reach the milestones that will open the door to the seed. You have to raise just enough to achieve this, without excessively diluting the founders. An oversized pre-seed round can become a trap if the objectives are not achieved.

Who are the pre-seed investors?

Pre-seed investors form a diversified ecosystem.

Business angels

Business angels are the most active in pre-seed. They invest between 10,000 and 100,000 euros each, often in a syndicate, and provide networking and mentoring.

Pre-incubators and accelerators

Structures like Station F or Numa support founders with a structured program and access to a network of investors.

Specialized pre-seed funds

Funds like Kima Ventures or Breega are positioning themselves specifically in this phase with tickets from 50,000 to 300,000 euros.

Love money and public subsidies

Love money remains a fréquent source. The Bourse French Tech from Bpifrance and regional aid constitute valuable non-dilutive financing.

What légal instruments should I use for pre-seed financing?

The choice of the légal instrument is decisive for the flexibility of the arrangement.

InstrumentAdvantagesDisadvantagesTypical usage
Capital increaseSimple, transparentImmediate dilution, évaluation necessaryOrganized tour
BSA-AIRFlexibility, deferred évaluationLégal complexityQuick angel investment
Current account agreementSpeed, no dilutionPriority reimbursementTemporary founding contribution
Participatory loanDéductible interestFinancial cost, compulsory reimbursementAdditional financing

The BSA-AIR: the preferred instrument in 2026

The BSA-AIR (Share Subscription Warrants - Réservé Investment Agreement) has established itself as the référence instrument for French pre-seed rounds. It makes it possible to defer the valuation of the company until the next round of financing, thus avoiding difficult negotiations on a premature valuation.

Hayot Expertise Advice: at pre-seed, credibility is often born from clarity. A founder who knows how to explain his assumptions, his costs and his thresholds inspires more confidence than an overpromising and vague file. The choice of légal instrument must be validated by an accountant familiar with startups.

How to prepare your pre-seed fundraising?

Succeeding in pre-seed fundraising requires methodical preparation. Here are the key steps:

1. Validate the market thesis

Before raising, make sure the problem you are addressing is real, painful, and that potential customers are willing to pay for a solution.

2. Build a Working MVP

A prototype or an MVP (Minimum Viable Product) is often the minimum expected. It demonstrates your ability to execute and allows you to collect initial user feedback.

3. Prepare an investor file

Your file must include:

  • a clear pitch deck (10 to 15 slides);
  • a business plan with explicit assumptions;
  • a présentation of the founding team;
  • an analysis of the address market;
  • a detailed fund use plan.

4. Structuring the légal framework

The constitution of the company, the shareholders' agreement and the protection of intellectual property are essential prerequisites.

5. Target the right investors

Identify those who have already invested in your sector and your stadium. A relevant pre-seed investor understands your market and can support you all the way to seed.

Errors that weaken a pre-seed crop

Some errors recur frequently:

  • absence of clear thesis: the founder does not know how to explain why his project deserves to exist;
  • use of funds too broad: the budget does not correspond to any specific milestone;
  • cap table mal pensee : répartition du capital desequilibree ou dilution prematuree ;
  • insufficient légal documentation: shareholders' agreement absent, intellectual property not protected;
  • confused indicators: absence of clear KPIs;
  • burn level not controlled: expenditure forecast inconsistent with the amount raised.

Frequently asked questions

What is the différence between pre-seed and seed?+

Pre-seed occurs at the idea or prototype stage, with amounts of 100,000 to 500,000 euros in France. The seed concerns projects with a valid product, for amounts of 500,000 to 3 million euros.

How long does a pre-seed round last?+

A pre-seed round generally takes between 3 and 6 months, from preparing the file to signing the first checks.

Do you need a business plan for a pre-seed raise?+

Yes, but not in the traditional sense. We expect a framework with explicit assumptions, investment priorities and clear milestones.

What dilution to accept in pre-seed?+

A dilution of 5 to 15% is reasonable. Beyond that, the founders risk being too diluted in subsequent rounds.

Is the pre-seed accessible without turnover?+

Absolutely. The majority of pre-seed rounds concern projects without income. Investors evaluate team quality, market size and execution ability.
