Meet our founders

Built on a belief. Driven by purpose.

Clausom begins with a simple conviction: the technology people rely on should respect the people who use it.

Founder & CEO

Mudassirkhan Pathan

LinkedIn

Mudassir is an engineer and technology entrepreneur who creates technology that gives people more control over their digital lives. For more than 11 years, he was a co-founder of Intangles, the Pune-based predictive AI company, where he built the engineering organisation from the ground up and helped lead the company from a first product to a Series B. By the time he stepped down as Head of Engineering in January 2026, Intangles was monitoring more than 500,000 vehicles across four continents and had closed a $30 million Series B led by Avataar Venture Partners.

His engineering depth spans data, software architecture, systems and product engineering, and he works from first principles with a bias for execution. He matches that with how he leads: he builds teams that see the problem clearly, take pride in their work, and ship products that are both functional and delightful.

As founder and CEO of Clausom, he sets the company's direction and still leads the engineering of its flagship product, holding both to one standard: Zero knowledge, Zero compromise. He believes technology should empower people, not betray them, and that privacy-preserving technology should be the default in the modern digital world. A quantum-computing geek and philomath, he is endlessly curious about how technology creates new industries, and he built the product for where cryptography is heading, not only where it is today.

What we build

Security for fiveeveryday moments.

Our scope covers how people type, sign in, store, connect and pass information on. Our first product starts with storing, signing in and passing on — more to share soon.

The idea

Privacy built intothe architecture.

Most services protect your data with policies: promises about how they will behave with information they can read.

Zero-knowledge design removes the need for the promise. The service is built so it never holds readable data in the first place.

  1. 01

    On your device

    Information is encrypted on your device before it leaves.

  2. 02

    On the server

    The service stores only encrypted data it cannot read.

  3. 03

    The keys

    The keys stay with you, not with Clausom.

  4. 04

    Who can read it

    You, and the people you choose.

Why we exist

Usefulness shouldn’tcost you access.

Almost everything personal now lives online. The more useful a service becomes, the more it tends to ask for — and people rarely get a real choice.

Clausom exists to show that a service can be useful without making access to private information the price of entry.

Now digital

  • Documents
  • Identities
  • Conversations
  • Finances
  • Memories
  • Relationships

Does a service really need to see all of this?

Our answer

Rarely.
So we design for less.

Our vision

Zero knowledge asthe standard, notthe exception.

We imagine a future where people benefit from zero-knowledge security without needing to seek it out or understand it first — simply a better foundation for digital services.

Not a feature.

A default.

Our mission

Protect
every person’s
digital life.

How we approach it

  1. 01

    Design out access

    Products built so they cannot see, store or sell what they hold.

  2. 02

    Start where it matters most

    Our first product begins with the information people most need to protect and pass on.

  3. 03

    Grow one product at a time

    Extend the same architecture, deliberately, across a privacy-first ecosystem.

Principles

Five principles,in practice.

No data monetisation.

Your digital life is not for sale. We build technology to protect your data, not profit from it.

01 · Privacy First

Privacy comes before the feature.

Privacy is considered at the start of every decision, not added once the product is finished.

In practice

A feature that cannot work without unnecessary access to your information is redesigned until it can.

Our beginnings

Started with aprinciple, not aproduct catalogue.

We are a young company and say so openly. Here is what has happened so far, and what is still a plan. Starting in India, with a global ambition.
