OUR STORY
It Started With an Email. And a Mother. And a Moment.
THE SPARK
An Unexpected Email. A Daughter’s Gift. A Mother Named Coty.
In January 2026, Sergio Cutrera received an email from Matthew McConaughey’s newsletter. The subject was one word: Unbelievable.
Inside, McConaughey cited a Harvard study that stopped Sergio mid-scroll. Harvard psychologist Prof. Ellen Langer had taken a group of elderly men and immersed them in the sights, sounds and culture of 1959 — the music they loved, the TV shows they watched, the news of their era. By the end of the week, they were measurably younger. Physically. Not metaphorically.
That same week, Sergio’s daughter handed him a gift — McConaughey’s poetry book. She didn’t know about the email. Some coincidences arrive in pairs.
“If we turn the clock back psychologically, can we also do it physically?”
— Prof. Ellen Langer, Harvard University
Sergio thought of his mother, Coty. And he thought: what if the past wasn’t just a memory — what if you could step back into it, anytime, through the screen?
That question became Tiempa.
THE SCIENCE
The Counterclockwise Study, 1979
Prof. Ellen Langer’s landmark 1979 study took eight men in their 70s and immersed them in a retreat designed to feel exactly like 1959. No mirrors. Portraits of their younger selves. Perry Como on the radio. Ed Sullivan on black-and-white television. Current events discussed as if they were happening now.
They didn’t just remember the past. They lived it. And by the end of the week, they were measurably healthier — improved flexibility, memory, hearing, posture, and cognitive function. Outside observers said they looked younger. The science said they were.
Tiempa is not a medical tool. It is not therapy. It is entertainment — built on the simple, proven idea that immersing yourself in the world you grew up in feels profoundly, powerfully good.
THE PLATFORM
A Digital Time Machine. Built for Real People.
Tiempa is a Retro Time Travel TV platform. You pick a decade. You pick a country. And it takes you back — curated TV shows, films, music, news and advertising from 1940 to 2020, organised by year.
It is not a streaming service. It is not a clinical tool. It is a place to sit down, press play, and feel at home in a moment that shaped you.
Australia first. Argentina. Then the world.
THE FOUNDER
Sergio Cutrera
Sergio is a Sydney-based entrepreneur, technologist and solo founder. He built Tiempa from a personal conviction: that the stories, songs and moments we grew up with deserve a better home than a scattered YouTube search.
He is the son of Coty — whose world, like so many others, became smaller as she got older. Tiempa is partly his answer to that.
He is also the founder of MeliGuard, an aged care wellbeing platform developed in collaboration with Cicada Innovations in Sydney.
