Our Story

Why We Started Defacto

We built Defacto because we saw what happens when quality has no way to prove itself - and when customers are left guessing.

01
Built a brand from scratch

Created OMG Bubble Tea - the first RTD bubble tea for European retail. Austrian tea extracts. Dutch-engineered pearls, no shortcuts. Scaled to €15M+ revenue.

02
Watched ghost brands destroy the category

Cheap knockoffs from shadow factories from China flooded the market. Food colorings instead of real extract, metals and everything that can be bad in the product.

03
The market rewarded the wrong brands

Quality didn't matter - marketing did. Consumers had no way to tell the difference between an honest product and a convincing fake.

04
Became a parent, saw the other side

Standing in a store aisle, reading ingredient labels, realizing nothing could be trusted at face value. The same system that failed me as a founder was failing me as a dad.

05
Understood what was actually missing

Not another badge or certification. Real infrastructure that takes actual lab data and makes it visible to consumers - right on the product page.

Started Defacto

We turn your Certificate of Analysis into something shoppers can see and understand. We're not here to judge - we're here to make your honesty visible.

Real Labs. Real Science. Real Results.

Every product verified twice - by an independent lab and Defacto's Quality department - then published right on the product page.

Where the first test happens

An ISO 17025-accredited lab runs the same instruments the FDA would use if supplements were tested before market. The sample is the same one you can buy.

Where the second pair of eyes comes in

Our quality team reads every certificate against the label claims. Under-dosed, off-spec, or contaminated - badge doesn't go live. No exceptions, no override.

The moment
The moment

Where the work finally pays off

A person flips a bottle before checkout. They see the badge. They open the report. They read the numbers - and decide. That's the whole point.

Scientists. Builders. Parents.

We've built brands, shipped products, and we know what it's like when consumers can't tell the real from the fake.

Quality & Science
Reviewed by our Quality & Science team.

Our Promise

To brands

We will never sell a badge. Defacto verification has to be earned through evidence. There is no shortcut, no premium tier, and no way to buy a result. A product either meets the standard or it does not.

That is the only way trust works.

To consumers

If you see Defacto on a product page, the data is real. The lab is independent. The results are verified by us and public. No exceptions. You can manipulate influencers. You can manipulate reviews. You can't manipulate science.

Our Mission

We are building the trust layer for modern commerce.

A world where brands do not just make claims - they prove them. Where customers do not have to decode labels, search for hidden lab reports, or guess what is real. And where every verified product page tells the story behind the product, not just the story written for marketing.

One claim. One ingredient. One verification at a time.

A new standard for truth

We're building a new standard for truth. One where every claim is earned, every ingredient is verified, and every product page tells the real story - not the marketing one.

Every claim earned Every ingredient verified Every product page real
