Why a specialized startup lawyer?
Launching a startup means navigating a complex legal environment where intellectual property, digital law and corporate law intersect.
Whether you're building a SaaS platform, an AI solution, an e-commerce marketplace or an innovative service, the legal decisions made in the first weeks are structuring. Unlike generalist firms, INFLUXIO combines deep IP expertise with specific knowledge of tech ecosystems. We understand your product, your market and your growth challenges.
Creating your startup: legal foundations.
The legal structuring phase determines much of your startup's future.
Choosing the right legal structure.
The SAS (Simplified Joint-Stock Company) is the standard for French startups: statutory flexibility, ability to create share classes, BSPCE compatibility, and attractiveness for investors. SASU for solo founders, SAS as soon as a team forms.
Drafting bylaws.
The bylaws define governance rules, capital allocation, and decision-making processes. INFLUXIO drafts tailored bylaws that anticipate future fundraising rounds and partner changes.
Shareholders' agreement.
The shareholders' agreement (pacte d'associés) complements the bylaws: vesting clauses, good/bad leaver, tag-along/drag-along, preemption rights, non-compete. A well-drafted agreement prevents costly disputes between founders.
Founders' IP assignment.
All intellectual property developed by founders before incorporation must be formally assigned to the company. Without this, investors will refuse to invest and the company's valuation is compromised.
Fundraising: legal support from seed to Series A.
INFLUXIO supports startups through every stage of fundraising, whether pre-seed, seed or Series A.
Term sheet negotiation.
The term sheet sets the terms of the investment: valuation, investment amount, governance rights, liquidation preference, anti-dilution protection. We negotiate terms that protect founders while remaining attractive to investors.
Due diligence.
Investors conduct legal, financial and technical due diligence before investing. INFLUXIO prepares your data room, anticipates investor questions, and manages the due diligence process to minimize friction.
Investment documentation.
Investment protocol, bylaw amendments, shareholders' agreement update, subscription forms: INFLUXIO drafts and negotiates the complete investment documentation.
Post-closing and investor relations.
Post-fundraising governance: information rights, strategic committee, reporting, anti-dilution, ratchet.
BSPCE, BSA, BSA AIR and employee incentives.
Attracting and retaining talent is a key challenge for startups. BSPCE (Bons de Souscription de Parts de Créateur d'Entreprise) are the most tax-efficient tool for startups less than 15 years old.
BSPCE: conditions and implementation.
BSPCE are available to SAS companies less than 15 years old, not controlled by another company, and subject to corporate tax. The exercise price, vesting schedule and exercise conditions must be carefully defined.
BSA (Share Subscription Warrants).
BSA are more flexible than BSPCE and can be issued to advisors, consultants and board members who don't qualify for BSPCE.
BSA AIR (Accord d'Investissement Rapide).
The BSA AIR is a simplified financing instrument inspired by the American SAFE (Simple Agreement for Future Equity). It allows an investor to provide funds quickly in exchange for BSA whose exercise price will be set during a subsequent funding round, with a negotiated discount.
Ideal for early-stage funding (pre-seed, seed), the BSA AIR avoids premature valuation negotiations and accelerates financing operations.
IP and tech protection for startups.
Your intellectual property is your startup's primary asset, regardless of your sector.
Trademark strategy.
Your brand name must be protected by trademark registration (INPI, EUIPO) before launch. INFLUXIO handles prior art searches, filing and monitoring.
Software and algorithm protection.
Software is protected by copyright in Europe. Your code, architecture and documentation must be properly documented and assigned. AI models require specific protection strategies.
Data and GDPR compliance.
GDPR compliance is a prerequisite for any startup handling personal data. INFLUXIO implements privacy by design, drafts privacy policies, and sets up compliant data processing frameworks.
Trade secrets.
Protection of confidential information (French law of July 30, 2018): NDA, access restrictions, traceability.
Tech and commercial contracts.
Business and technology relationships must be properly framed, from development to market launch.
Terms of service / Terms of use.
Mandatory for any e-commerce, marketplace or SaaS activity.
SaaS contracts and software licenses.
SLA, uptime, reversibility, liability, digital law compliance.
Development contracts.
IP rights assignment on outsourced developments. Without an express clause, rights remain with the contractor.
Partnership agreements.
Commercial, technology or distribution partnerships drafted to protect your interests and IP.
GDPR, AI and cybersecurity compliance.
GDPR compliance is a prerequisite scrutinized during due diligence. INFLUXIO supports you: processing records, privacy policies, data processing agreements, DPIA, and cybersecurity incident management. For startups using AI, we align GDPR obligations with those of the AI Act.
The INFLUXIO approach: a firm rooted in innovation.
INFLUXIO is not a generalist corporate firm. We support startups that innovate in tech, AI, SaaS, e-commerce, media and creative industries. From intellectual property to digital law, from corporate structuring to fundraising, we provide comprehensive support perfectly tailored to the challenges of high-growth companies.
Useful glossary in startup law.
- Shareholders' agreement
- extra-statutory agreement between a company's shareholders to organize their relationships (preemption, drag-along, tag-along, leaver, vesting clauses), distinct from the bylaws.
- BSPCE (Founder Share Warrants)
- incentive instruments reserved for employees and managers of startups (Article 163 bis G of the French General Tax Code), benefiting from a favorable tax regime.
- Term Sheet
- non-binding letter of intent setting out the main conditions of a fundraising round (valuation, governance, investor protection clauses) before signing the final documentation.

FAQ
Frequently asked questions.
Startup creation package (bylaws, shareholders' agreement, BSPCE): €3,000-8,000 excl. VAT. Fundraising support: €5,000-15,000 excl. VAT depending on complexity. INFLUXIO offers packages adapted to startups.
From the very beginning. Founders' IP assignment, choice of legal structure, and the shareholders' agreement are critical decisions that are costly to fix later.
A BSPCE (Bon de Souscription de Parts de Créateur d'Entreprise) is a share option specific to French startups under 15 years old, offering favorable tax treatment for employees and founders.
The BSA AIR (Accord d'Investissement Rapide) is the French equivalent of the American SAFE (Simple Agreement for Future Equity). It allows an investor to fund a startup without immediately setting a valuation. The BSA exercise price is determined at the next funding round, with a negotiated discount (typically 15-25%). It's the ideal tool for fast early-stage fundraising.
