University of Porto Startup Develops Eco-Friendly Razor Gentler on the Skin

March 11, 2026

A startup Decimal Devotion, incubated at UPTEC – the Science and Technology Park of the University of Porto, recently launched what it describes as an ‘environmentally friendly and gentler on the skin’ shaving razor.

In a statement, it explains that the new device, named NATU, combines the ‘speed and convenience of disposable blades with the benefits of traditional razors, the safety razors‘.

The product is made from solid aluminum, rust-resistant, and entirely produced in Portugal. It has a flexible head that adapts to the body’s contours, can be used by men and women, and uses blades made from a fully recyclable material.

NATU’s creation follows the first brand launched by Decimal Devotion, TATARA Razors, a stainless steel shaving razor aimed at the male audience.

“With the feedback we have received over the last nine years, we have realized that many users appreciate the ecological philosophy of traditional shaving machines, but they face adaptation difficulties or miss the convenience of disposable blades that can be found anywhere and are easy to use in areas such as underarms, legs, or head,” says João Gomes, one of the creators of NATU, alongside Luís Oliveira and André Guimarães.

All of them mechanical engineers trained at the Faculty of Engineering of the University of Porto, so NATU is the result of the founders’ learnings, as well as their knowledge in casting, machining, laser and prototyping.

NATU, priced at 59 euros, can be used with standard blades, which cost about seven cents each and can be used three to five times, “thereby representing a large saving on blades in the long term,” say the creators.

The funding was secured through the Kickstarter crowdfunding platform, which allows users to support the project directly with an amount of their choosing, or through early purchase of the product at a lower price.

With the initial goal of raising 10,000 euros of funding, the team surpassed this target and raised about 16,000 euros from over 250 supporters.

2026 marks the start of NATU’s journey, which is now available for purchase through the brand’s website.

Regarding the future, João Gomes says the team wants to go beyond the online market. “We intend to position NATU in pharmacies, stores and supermarkets with a sustainable component,” he reveals.
