Our story

You only wanted
to get in.

You came online to get something done. First came the form: your name, your email, your phone number. All that, just to get in.

And somehow, it followed you home.

An overflowing inbox. Texts you never asked for. Unfamiliar numbers you let ring. There’s a reason we rely on spam filters and screen our calls.

Our data is already out there. Each new account can add another link back to us, connecting what we do to who we are.

Meanwhile…

Platforms like Facebook, Google, Instagram and TikTok collect your data under the terms you agreed to.

You’re told your data has no value. Yet it powers personalization and earns them trillions of dollars from companies looking to reach you.

You create the value. They control the data and keep the revenue.

What if we broke that chain?

What if getting in didn’t mean giving yourself away?

What if that data could come directly from the owner—you?

Those are the questions that started Mementom.

Mementom lets you sign in without giving the site your name, phone number or an email tied to your identity. Without giving yet another piece of yourself away.

A company can still remember your preferences and offer something that fits. A relationship built around what you need, without asking who you are.

See how it works

Your access. Your choice.

You’re in control

To create your keyring, pick an image or take a photo. Type the caption it brings to mind. That’s your first key, and one is enough to get started.

Add more keys, change them or remove them whenever you need to. You decide what stays and what goes.

When you sign in to a Mementom partner, a secure window randomly picks one of your keys. It shows you the picture and asks for its caption. If your keyring has the right access, you’re in.

What does your data get you?

Your sizes, tastes and interests can make recommendations more useful and offers more relevant, without telling a company who you are.

Clothes that fit. Suggestions that reflect your tastes. Experiences that remember your preferences.

You choose what’s worth it.

In Mementom, you can receive offers, questions and requests to buy or subscribe to relevant data. Choose what interests you. Ignore the rest.

You choose what to share, when, and with whom.

Get paid for what you share.

Your interests, experiences and opinions have value. We’re building ways for you to earn through Mementom by answering questions, engaging with offers or sharing insights you choose.

You decide what’s worth sharing and what you’ll accept in return. Taking part is always your choice.

Mementom is always free for you to use.
No fees, whether you choose to earn or not.
