Encrypted electronic signatures, powered by AI and available in 47 languages

The global electronic-signature market is projected to exceed $35 billion by 2030 (Grand View Research, 2024). It is one of the decade’s fastest-growing segments. Yet it has settled into four compromises that few people now question.

In summary

Project overview

The challenge

Bring together document sovereignty, ease of use, competitive pricing and international reach in a market led by US electronic-signature providers.

Our work

Design and build, in six months, an encrypted platform powered by Mistral AI, hosted in France and localised into 47 languages.

The result

A production-ready application starting at €25 per user per month, with an NPS of 86 in beta and sovereign document infrastructure.

Context

The global electronic-signature market is projected to exceed $35 billion by 2030 (Grand View Research, 2024). It is one of the decade’s fastest-growing segments. Yet it has settled into four compromises that few people now question.
02 — Challenge

The challenge

No mainstream electronic-signature platform combines the four capabilities the European market expects but still cannot obtain in one place.

  • Pricing remains high.

    Established providers charge between €38 and €62 per user per month (public pricing for DocuSign Business and Yousign Pro, May 2026). For a ten-person team, the annual bill exceeds €4,500 before add-ons. The pricing model has not evolved in a decade.

  • Data sovereignty is not guaranteed.

    Market leaders fall under the US CLOUD Act. Even when data is hosted in Europe, it remains legally accessible to authorities outside Europe. For a law firm, notary, clinic or local authority, this is a structural vulnerability.

  • Confidentiality depends on trust, not architecture.

    On every established platform, the provider can technically access the content of signed documents. Confidentiality is a contractual promise, not a cryptographic property. If the server is compromised, the documents can be read.

  • The user experience remains overly technical.

    Interfaces are designed for legal departments, workflows are cumbersome, and AI is added as a marketing veneer with no meaningful effect on the workflow. Individuals, freelancers, SMEs and mid-market companies are poorly served.

Validature was designed to address all four blind spots at once.

03 — Solution

The solution

Logiks designed, developed and operates Validature end to end, from the initial product brief to the infrastructure’s daily operation. Six months of development brought together a multidisciplinary team of five, working day and night on a project that allowed no careless trade-offs. Applied cryptography, AI integration, a carefully crafted front-end experience, deep localisation and European regulatory compliance all had to be delivered simultaneously.

In 1883, Auguste Kerckhoffs established the founding principle of modern cryptography: a system’s security must never depend on keeping its mechanism secret, but on keeping its key secret. One hundred and forty years later, we built Validature on precisely that foundation.

Vault Encrypted: confidentiality by architecture

This is Validature’s most structurally important capability. We benchmarked the leading general-purpose electronic-signature platforms for freelancers, SMEs and mid-market companies—DocuSign, Yousign, Adobe Acrobat Sign and Dropbox Sign—and found no native mode equivalent to Vault Encrypted. Documents are encrypted on the client side; the exclusive key is not retained by the provider; and the platform is technically unable to read the signed content.

Specialist products exist in the high-security segment, but they serve a different market, with heavier integration, less mainstream usability, and different budgets and adoption requirements. For the most sensitive use cases, documents are encrypted before reaching the server. The decryption key never resides server-side: it is generated and retained in the sender’s environment, then transmitted to the recipient through a controlled access mechanism.

Validature never sees it, stores it or has the ability to reconstruct it. No key on the server. No possibility of reading the document. No reliance on a contractual promise. Confidentiality is guaranteed by design. If James Bond had to sign a mission contract, he would use Validature.

French AI from Mistral, integrated into the workflow

We chose Mistral because document data could not be allowed to leave the country. Validature embeds French AI at the heart of every stage: automatic document classification (contracts, certificates, NDAs, quotations and deeds), contextual drafting assistance, legal-consistency checks, clause suggestions, summary generation and identity-document processing. Artificial intelligence does not merely support the signing process; it orchestrates it.

Automatic brand personalisation

Validature analyses each client’s website and extracts its visual identity: colours, typefaces, tone and hierarchy. That identity is then applied automatically throughout the recipient journey, including invitation emails, the signing page, notifications and acknowledgements. Signatories receive an experience branded to the sender without any manual configuration. Where competitors charge extra for personalisation, Validature includes it by default.

AI-enhanced KYC

Identity verification is built in. Automated identity-document processing, biometric checks, fraud detection and cross-verification are coordinated through an AI layer that reduces friction without weakening regulatory standards. Surgical precision, without the interrogation.

47 languages

With 47 languages available throughout the signing experience, Validature exceeds the public benchmarks of the market’s leading providers: DocuSign reports 44 localised languages, Adobe Acrobat Sign 34, Dropbox Sign 22 and Yousign eight. Validature adapts automatically to each market’s legal and cultural conventions, including contractual wording, legal formats and typographic hierarchy. A contract signed between a Paris law firm and a Japanese partner is displayed according to the conventions of each party.

Compliance and sovereignty

Validature operates SES and AES signing workflows in accordance with the eIDAS framework: signatory identification, one-time passwords, audit trails, evidence of consent, document integrity and detection of subsequent changes. QES deployment is under way, as is ISO 27001 certification. Hosting is provided by OVH in France and AI by Mistral in France. Signed documents are neither stored nor processed by any US hyperscaler.

04 — Impact

The impact

Six months of development. A production application available at validature.com.

At €25 per user per month on monthly billing, Validature is priced below every comparable provider: €60 for DocuSign Business Pro, €48 for Yousign Pro and €28 for Adobe Acrobat Pro for Teams (public pricing, May 2026). It also delivers strict document sovereignty: OVH hosting in France, Mistral AI processing, European storage, and no transfer of signed documents to US hyperscalers.

Non-sovereign dependencies are restricted to specialist functions—payment, one-time passwords and cryptographic key management—with no access to the content of signed documents.

Three effects.

  • First, a measurable user experience.
    Net Promoter Score reached 86 during the beta phase, a level few B2B applications achieve at launch. Every workflow was designed to minimise the number of clicks required to achieve the same outcome. AI handles everything that can be automated: field recognition, pre-filling, signatory suggestions and error detection before sending. The user signs; Validature handles the rest.

    Production usage metrics—including signature volume, completion rate and average workflow time—will be published over the first months of operation.

  • Second, sovereignty embedded in the architecture, not written into a contract.
    Vault Encrypted is designed to make documents unreadable even if the server is compromised, provided the user-side decryption key remains secure. Confidentiality is no longer a commercial promise; it is a verifiable technical property.

  • Finally, proof that sovereignty and affordability are not contradictory.
    We are often told that building in France costs three times as much. Validature demonstrates the opposite: sovereign hosting, sovereign AI, European compliance and a lower price than US providers. Sovereignty is not a tax; it is an architectural choice.

If your organisation is looking for a sovereign electronic-signature solution, or if you are developing a product with comparable technical demands, we would be happy to discuss it.
