ABOUT US
What is Livio?
Livio is an AI-guided weight loss app with a personal coach built in. Our mission is to help you lose weight in a way that actually fits your life – no rigid diets, no all-or-nothing pressure, just consistent progress guided by AI every single day.
Livio was built because we know weight loss is hard – not because people lack willpower, but because most apps just track numbers without ever guiding you. We created something different: an AI coach named Kai who learns your habits, builds your personalized weight-loss plan, and adapts when life gets in the way.
We believe sustainable weight loss should be achievable for everyone — no matter how busy your schedule, how many diets you’ve tried before, or where you’re starting from.
Why We Created Livio?
We created Livio because we were frustrated with weight loss apps that track everything but guide nothing. Counting calories in a spreadsheet doesn’t tell you why the weight isn’t coming off. Logging workouts without a plan doesn’t get you to your goal. We wanted to build something smarter — an AI-guided weight loss app that actually coaches you, not just records you.
We also know that most weight loss programs fail because they’re built for perfect days — and nobody has perfect days. So we built Livio to work on the messy, busy, real days too. Your AI coach Kai adapts your plan, picks you back up when you slip, and keeps your weight loss moving forward without making you feel like a failure. That’s the app we wished existed. That’s why we built Livio.
Co-Founder & CEO
Leo Gestetner
20 years ago, I was almost 250 pounds and about 35% body fat. A good friend then got me into running, having never done much exercise before!
Fast forward 20 years and I’m under 160 pounds and 12% body fat and running the fastest I ever have, doing half marathons and triathalons.
I’ve realized I want to build a sustainable lifestyle and longevity — not living longer but living healthy until the end. For me, this journey includes physical, spiritual, emotional, and intellectual health.
I have been a serial entrepreneur for over 30 years and am currently the Co-Founder of Thankz, Zenvoy and Heath Capital.

Jenna Gestetner
I have 6+ years experience working at the intersection of health care, design, and marketing – helping brands communicate, build community, and make health feel more human. I am also a Certified Personal Trainer and Certified Nutrition Coach.
My perspective really changed because of my own experience living with chronic conditions. I grew up with undiagnosed health issues but wanted to see the same results as everyone else I saw – Keto, 75 Hard, you name it. None of it worked. I was burned out and it wasn’t realistic for my lifestyle and how my body functions.
So, I decided to use the science behind why those methodologies work and use them to build habits that do fit my lifestyle. I started implementing habits like walking a mile every morning, drinking enough water, and eating more protein. These habits may seem small, but they had a drastic impact on my life.
Even when my health was at its worst, I felt the best about my life, because I finally felt in control of my health. Each and every day, I make decisions to do small things that make me feel good and serve myself. That’s exactly what Livio is built for: helping you build habits that actually fit your life and support your health long-term, one action at a time.
Co-Founder & CTO
Nick Brandt
Originally I was a chef with a deep passion for food, but life had other plans. Over the past 20+ years, I transitioned into the tech world, managing SaaS projects, where my focus has been on leading remote teams and hiring offshore talent.
As Co-Founder and COO of Thankz, I help companies efficiently recruit and manage remote workers. My technical knowledge and love for food and cooking make working with Livio the perfect outlet for my interests.
When I’m not working, I indulge in my passions—travel, photography, art, going to the gym, and, of course, cooking. In the face of the challenges of middle age, like managing my weight, I practice low-carb diets most of the time and remain committed to staying healthy and active.
Co-Founder & AI
Kai
Hi, I’m Kai — Livio’s AI weight loss coach and one of the co-founders of this app. Yes, I’m AI. But I’m not your average chatbot. I was built with one purpose: to help you lose weight in a way that actually works for your life.
You can find me on Livio’s social channels, where I break down the science behind weight loss — from how to break a plateau, to the best macros for fat loss, to why sleep matters more than most people realize.
Inside the app, I’m your 24/7 AI-guided weight loss coach. I’ll build your personalized weight loss plan, log your meals from a photo or description, create fat-burning workout plans, track your fasting windows, and check in on your progress every single day.
Whether you want to lose 10 lbs or 100 lbs, whether you’ve tried every diet or are starting from scratch – I meet you where you are and guide you forward. That’s what an AI weight loss coach should do. That’s what I’m here for.
