Non-compete and non-solicitation clauses in tech startups: practical guide 2026

Why these clauses are strategic in tech startups

In startups and IT services companies, value rests on code, data, products and customer relationships. When a developer, enterprise salesperson or data lead leaves, leaked know-how or a move to a competitor can be very costly. Non-compete and non-solicitation clauses protect these interests, but are valid only if they meet strict French employment-law conditions.

The principle is simple : any restriction on freedom to work must be justified and proportionate. This guides judicial and administrative analysis (see in particular the Labour Code and case law presented by the ministry and official portals : code.travail.gouv.fr — Labour Code guidance, Service-Public.fr — official guidance, Legifrance — art. L1121-1).

Non-compete clause : validity conditions and good practice

Cumulative conditions (reminder of the principle)

• Written : the clause must appear in the employment contract (or a signed amendment).
• Legitimate interest : protection of a real asset (customers, secrets, product roadmap, etc.).
• Limited in time and geographical scope, and confined to a defined activity.
• Proportionate to the employee's duties (case-specific assessment).
• Specific financial compensation, paid after termination throughout the clause's application.

These are established requirements reiterated by the administration : Labour Code — Non-compete guidance and Service-Public.fr — official guidance. They derive from proportionality (freedom to work : art. L1121-1 C. trav.).

Duration, geographical scope and functional scope

• Duration : aligned with the actual risk of diversion or reuse of know-how (frequently 6 to 12 months in tech, up to 24 months in specific justified cases). The longer the period, the more substantial compensation should be.
• Geographical area : restricted to markets actually served (e.g. Île‑de‑France or the EU if the activity was pan-European). Worldwide coverage requires exceptional justification.
• Activities covered : describe the prohibited activity (e.g. : “development and marketing of X cybersecurity SaaS solutions for enterprise customers”), and avoid disproportionate general wording (“any competing activity”).

Financial compensation : amount, payment and social contributions

• Calculation formula : percentage of reference gross salary (average over the last 12 months, including variable pay) or an indexed fixed amount.
• Payment : generally monthly throughout application. Avoid a single payment at the end, often considered unfavourable to the employee.
• Social contribution treatment : non-compete compensation is treated as remuneration and subject to social contributions (URSSAF : urssaf.fr — social contribution authority).

Warning : without specific compensation, the clause is void and ineffective (Service-Public.fr — official guidance).

Employer waiver : deadlines and drafting

• Expressly provide an employer right to waive unilaterally, with a clear deadline (e.g. : “up to 15 calendar days after notification of termination”), notification arrangements and release effect.
• If the employer waives in the required form and within the deadline, the clause ceases to apply and future compensation is not due.
• Without a waiver clause, or if the deadline is missed, compensation becomes payable if the clause applies.

Plan exits (dismissal, resignation, mutually agreed termination (rupture conventionnelle)) to meet waiver deadlines.

Consequences of invalidity or breach

• Invalidity of a poorly drafted clause : no remaining prohibition; compensation already paid is sometimes reclassified as salary paid without being due.
• Breach of a valid clause : interim proceedings (temporary prohibition), damages, repayment of compensation received.

Non-solicitation clauses : customers, suppliers, employees

Non-solicitation seeks to prevent a former employee from approaching the company's customers or poaching its staff. Two frameworks must be distinguished.

In the employment contract

• Customer non-solicitation : if it actually restricts professional activity, it is often treated as a non-compete and must meet similar conditions (proportionality, duration, scope, dedicated compensation). Take care in tech, where the customer portfolio is key.
• Employee non-solicitation : possible, but with a restricted group of people covered (directly managed teams, key people), and limited duration (often aligned with the non-compete). If its scope prevents forming/managing a team in the same sector, it may be treated as a restriction on freedom to work and require the safeguards of a non-compete.

Useful reference : official general reminders on proportionality and freedom to work (L1121‑1 C. trav., Ministry of Labour).

In B2B (subcontracting, IT services companies, partnerships)

Clauses prohibiting solicitation of staff or customers in subcontracting agreements are permitted if proportionate (limited to relevant teams/projects, defined duration, no anti-competitive object). However, general no-poach agreements between competitors may constitute unlawful restrictive agreements under competition law (reduced mobility and wage competition) : see guidance on restrictive agreements on Service‑Public Pro — business guidance and Article 101 TFEU on EUR‑Lex — EU law portal.

If negotiating non-solicitation in a subcontracting agreement, use these subcontracting good practices and limit the clause to what is strictly necessary (project, named people, 6–12 months after the engagement ends).

Practical drafting : checklist for HR directors and founders

• Map the legitimate interest : source code, datasets, architecture, customer portfolio, pricing strategy.
• Calibrate duration (often 6–12 months) and area to markets actually targeted.
• Define the prohibited activity through sector/product keywords (e.g. “IAM SaaS for mid-sized companies in France”, not “any competing activity”).
• Set compensation : clear percentage of reference gross pay, monthly payment, specifics on variable pay/bonuses.
• Insert a waiver clause (short deadline, notification arrangements, release effect).
• Provide a reasonable penalty clause for breach (in addition to damages), ensuring proportionality.
• Coordinate with NDAs and intellectual property to cover secrets, code and sensitive data (see our NDA advice and source code protection).
• Check the applicable collective agreement (e.g. Syntec) : certain sector practices exist even without specific provisions. Our full review of choosing a tech startup's collective agreement and its effects.
• Choose the right employment contract and plan ancillary clauses (see permanent vs fixed-term startup contracts).
• Freelancers and non-solicitation : address this in B2B contracts and manage the risk of reclassification as employment.

Three practical tech scenarios

1) SaaS back-end developer

• Risk : reuse of proprietary architectures/procedures.
• Target clause : 12 months, France + countries where the product is marketed, activity restricted to “SaaS solutions in [field] for [customer segment]”, monthly compensation.
• Non-solicitation : key customers in the technical portfolio only, same duration.

2) Enterprise sales

• Risk : diversion of accounts and pipeline.
• Target clause : 6–12 months, area = territories covered, activities = selling competing products to the same account types, compensation adapted to variable pay.
• Non-solicitation : named customers (top 50), 12 months, active solicitation only (no ban on responding to unsolicited approaches if proportionality requires).

3) Head of Data

• Risk : leakage of algorithms, labelled datasets, MLOps strategy.
• Target clause : 12–18 months if justified, very precise functional scope (AI solutions for sector X), area = markets actually served, enhanced compensation.
• Non-solicitation : named data engineers and critical data partners, aligned duration.

Quick compliance checklist

• Signed contract containing the clause, clear wording, informed employee.
• Legitimate interest set out in the clause or preamble.
• Measured duration and area, precisely named activity.
• Specific compensation, calculation method and monthly payment specified (URSSAF : social contribution treatment).
• Employer's waiver right, deadline and arrangements notified.
• Defined non-solicitation scope : listed people/customers, short duration, no general no-poach agreement (see Service‑Public Pro — business guidance and art. 101 TFEU).

Quick FAQ

Is the clause valid without compensation?

No. Without specific financial consideration, a non-compete clause is void (Service‑Public.fr — official guidance).

Can all work for a global competitor be prohibited for 2 years?

Only if strictly justified and proportionate (markets actually served, duties performed). Otherwise, the clause risks invalidation (code.travail.gouv.fr — Labour Code guidance).

What about no-poach agreements between competing businesses?

Avoid horizontal no-poach agreements : they may constitute unlawful restrictive agreements (see Service‑Public Pro — business guidance and EUR‑Lex — art. 101 TFEU).
