About Ew2health

A small team. A specific problem. A long-term mission.

Ew2health was founded by a physician, a physicist, and an operator who all believed the same thing: that the way obesity care treats behavior is the reason most treatment fails. We are building the technology that fixes that.

Our mission

To make obesity something from the past.

It is a long mission. But every clinic we work with retains patients who would otherwise have disappeared — one decision at a time, supported by this technology.

How we started

The phone call that changed the design.

In the early days of building the weight-fluctuation algorithm, Renato needed real data to test his model. He called a friend and asked for help. The protocol was simple: step on the scale four times a week.

I need to see my weight four times a week?!? Renato, I can help you giving you US$ 10k but don't ask me to step on the scale everyday!

— A friend, on the phone.

That refusal was not laziness. It was the most honest research finding of the project: people avoid the scale because it has become a verdict — a daily confrontation with a number that can crush a week of effort in one reading.

That is the moment Sinque was born — not as a tracker, but as a numberless monitoring system designed around one truth: behavioral data only works if patients actually engage with the tool that captures it.

The team

Six people. One direction.

The founding team is a physician, a physicist, and an operator. The extended team brings clinical operations in Brazil and behavioral analytics research in the Netherlands.

Where we are

Two operational homes. One expansion underway.

Operational in the Netherlands and Brazil from day one — building into the United States next.

Netherlands

Headquarters

Ew2health B.V. is registered and headquartered in the Netherlands. The technical and product teams, the founders, and the corporate operation all run from here.

Brazil

Operational since founding

Brazil has been an operational home from the start. Clinical deployment, customer success, and much of our real-world data come from Brazilian medical weight-loss clinics.

United States

Expansion underway

The US is the world's most significant GLP-1 market and the next geography Ew2health is building into. Mayo Clinic Platform participation is part of that foundation.

Recognition and partnerships

Tested with serious institutions.

Validation program

Mayo Clinic Platform Data Accelerate

In 2026, Sinque was selected to participate in the Mayo Clinic Platform Data Accelerate program — contributing to and validating against tens of thousands of GLP-1 treatment records.

Clinical pilots

Petrobras and Hospital Israelita Albert Einstein

Pilot deployments in two of Brazil's most respected medical institutions: the Petrobras Workplace Nutrition Program (12- and 6-month real-world data) and Hospital Israelita Albert Einstein (earlier scientific pilot).

Accelerator

Health Impact Accelerator, Netherlands

Selected as a participating company in the Health Impact Accelerator program in the Netherlands, recognizing innovation in metabolic and obesity care.

SCIENTIFIC RESEARCH

LUMC and NeLL 

Together with LUMC and NeLL, Ew2health will investigate how predictive information can be best presented to different users. Ew2health received a grant for this project.

If you would like to talk to us — about your clinic, about partnership, about anything — the door is open.
