How Sara Sebti Turned a Banking Problem Into the AI Startup ShareID

In the startup world, some companies begin with market research, trend analysis, or investor predictions.

Others begin with frustration.

That was the case with ShareID, the French AI-powered digital identity startup cofounded by Sara Sebti and Sawsen Rezig.

What started as a personal inconvenience eventually became a privacy-focused identity authentication platform serving businesses dealing with fraud prevention, compliance, and secure customer verification.

But the most important lesson from ShareID’s story is not just the technology.

It is how the founders identified a painful real-world problem, understood the structural weakness behind it, and built a scalable business around trust, privacy, and digital security.

The Problem That Sparked the Company

In 2020, Sara Sebti changed her phone number.

That simple action unexpectedly locked her out of her bank account for nearly three weeks because the bank could no longer authenticate her identity through its existing security systems.

For most people, this would have been a temporary annoyance.

For Sebti, it exposed something much larger:
modern digital identity systems were still highly fragmented, inefficient, and dependent on outdated authentication methods.

She later described the experience as “incredible” because such a small change created a major access problem in a highly digital financial system.

That moment became the foundation of ShareID.

The Founders Behind ShareID

The company was not built by beginners unfamiliar with finance or technology.

Sara Sebti had nearly a decade of experience working with regulatory and risk-related requirements inside financial institutions. Her background included financial engineering and fintech entrepreneurship.

Her cofounder, Sawsen Rezig, brought deep technical expertise:

• PhD in computer vision
• Experience in biometrics
• Personal data security research
• Work experience at Cisco Innovation Labs

This combination mattered enormously.

One founder understood:

• financial regulations
• compliance systems
• enterprise pain points

The other understood:

• AI
• biometrics
• computer vision
• identity verification technology

Many startups fail because founders have only technical vision or only business understanding.

ShareID’s founders had both.

Understanding the Bigger Market Problem

Sebti’s frustration revealed a structural issue affecting millions of users and businesses globally.

Traditional identity verification systems rely heavily on:

• passwords
• SMS verification
• static credentials
• centralized databases

These systems create several problems:

• SIM swap fraud
• account takeovers
• data breaches
• poor user experience
• high operational costs
• regulatory complications

The global shift toward digital banking, fintech, remote onboarding, and online financial services increased pressure on businesses to verify users securely while reducing friction.

This became especially important after:

• rapid fintech expansion
• remote identity verification growth
• increasing cybercrime
• stricter privacy regulations such as GDPR

Research in digital identity and self-sovereign identity has increasingly emphasized the importance of user-controlled, privacy-preserving authentication systems.

ShareID entered this market at the right time.

What Makes ShareID Different

Many identity verification startups already existed before ShareID.

So the question became:

Why would businesses choose another identity platform?

The answer was privacy.

Unlike many competitors, ShareID positioned itself around a critical promise:
the company does not permanently store users’ personal or biometric data.

Instead:

• identity data is processed temporarily
• encrypted
• converted into unique hashes
• then removed from storage systems

This approach reduced:

• breach risks
• privacy concerns
• compliance burdens

At the same time, ShareID used AI-driven systems for:

• liveness detection
• anti-spoofing verification
• government ID analysis
• facial authentication

The platform claimed document authenticity precision rates up to 99.9% across more than 120 countries.

In practical terms, the user experience became dramatically simpler:
instead of repeated manual verification, users could authenticate themselves with a simple facial verification process.

The company described this as:
“authentication with official identity.”

The Hardest Early Challenge Was Not Funding

Many startup stories focus heavily on fundraising.

But ShareID’s early difficulty was data access.

To build effective AI systems capable of detecting authentic and fake identity documents, the startup needed high-quality datasets.

That was difficult.

According to Sebti, it took nearly a year to secure partnerships with the French military police to access the required databases for training their AI systems.

This is an important startup lesson:
deep-tech businesses often struggle more with infrastructure, datasets, regulations, and technical validation than with idea generation itself.

Ideas are cheap.

Execution barriers are not.

Why Timing Helped ShareID Grow

Several global trends accelerated demand for ShareID’s solution:

Identity fraud and digital impersonation have become major concerns across financial systems and online platforms.

Businesses increasingly needed systems that balanced:

• security
• compliance
• speed
• privacy
• user experience

That combination became ShareID’s positioning advantage.

Funding and Expansion

ShareID attracted backing from investors including:

• NewFund
• 212Founders
• CDG Invest

The company reportedly raised around:

• €2 million / approximately $1.9 million in seed funding

The startup also expanded:

• AI development operations in Morocco
• enterprise identity services
• international deployment ambitions, including the US market

ShareID’s Larger Vision

ShareID does not simply want to become another KYC platform.

Sara Sebti described the long-term ambition as becoming:

“the Google Connect with an official identity.”

That statement reveals the company’s strategic thinking.

The founders are not merely solving onboarding friction.

They are attempting to build a reusable identity trust layer for the internet.

If successful, such systems could eventually become core infrastructure for:

• banking
• fintech
• healthcare
• telecom
• enterprise authentication
• digital government services

Key Business Lessons from ShareID’s Journey

1. Great Startups Often Begin With Personal Pain

Sebti did not start with:

• market trends
• VC hype
• fashionable AI ideas

She started with:
a frustrating real-world problem.

The strongest startup ideas often emerge from:

• repeated friction
• inefficient systems
• painful customer experiences

2. Domain Expertise Creates Stronger Startups

ShareID’s founders deeply understood:

• regulations
• financial systems
• AI
• biometrics
• privacy infrastructure

This reduced the gap between:
idea → execution.

Many founders underestimate how important industry understanding becomes in regulated sectors.

3. Privacy Can Become a Competitive Advantage

Most companies treat privacy as compliance.

ShareID turned privacy into product positioning.

That distinction matters.

As cyberattacks and data breaches increase, user trust itself becomes a market differentiator.

4. Deep-Tech Startups Require Patience

Training AI systems, obtaining datasets, ensuring compliance, and building enterprise-grade security infrastructure take time.

Deep-tech success rarely happens quickly.

The invisible work is often:

• research
• partnerships
• infrastructure
• testing
• legal validation

5. Timing Matters as Much as Innovation

ShareID emerged during a period when:

• remote verification demand exploded
• digital fraud increased
• privacy laws tightened
• fintech adoption accelerated

Even strong ideas need the right market timing.
