Most tools designed to help people change behavior fail at the same point: the moment they add more steps than the habit they’re trying to build. Fitness apps are a clear example. The more features they add to help users track progress, the more work they create, and the more reasons users find to stop.

Zoe Pineau lived this problem before she decided to solve it. She lost 150 pounds in nine months by treating weight loss as a mathematical process, tracking every macronutrient with discipline. But when she tried to share that method with others, she hit the same wall every time: people understood it, agreed it worked, and didn’t do it. Friction got in the way of creating the habit of logging workouts and meals.

Her first app, MyFit Suite, tried to make tracking easier with a cleaner interface. Six years of development later, she concluded that easier wasn’t enough. In a saturated market, a better version of the same thing is still the same thing.

That experience led them to build Fitly AI, this time starting from a different approach: instead of complex features, it uses AI to let users describe their workouts and meals in one clean interface and coaches them to stay on track.

Practical Takeaways for Founders

Zoe and her husband Brad built Fitly AI in one month, compressing what previously took six years by using AI across development, design, and marketing. That speed only became possible once they were clear on what they were actually solving. Three lessons from that process are worth carrying into your own work.

Simplicity is a retention strategy

Friction is not a minor inconvenience; it is the reason most apps fail. Fitly AI was built around one question: what is the minimum a user needs to do to get the result they want? For Zoe and her husband, the answer was a single sentence. Every feature decision followed from that.

Lead with transformation, not product specs

When pitching investors who don’t share your context,  explaining rarely works. Zoe leads with her transformation photos because they make the problem undeniable before she explains the solution. Find the equivalent in your own story: the thing that requires no fitness knowledge to understand but makes the investor feel the gap your product fills.

Track everything, then share it

Zoe tracks everything the team accomplishes over 30 days and turns it into a short business update. It keeps the team motivated and keeps investors informed without requiring a formal meeting. In a long fundraising cycle, visibility compounds.

These three takeaways point to the same thing: decisions that reduce the distance between where someone is and where they need to be, whether that is a user, an investor, or your own team.

3 Magic Moments In The Episode

Zoe’s doctor told her the only options were surgery or hypnosis. She left that appointment believing nothing else was possible. What followed is one of the more unexpected founder origin stories I have heard so far.

AI-generated infographic about the contents of episode 158 of Women Disrupting Tech. The infographic was made using NotebookLM on the basis of the episode transcripts and the show notes from Riverside.

The book that changed her mindset

Standing in a store, Zoe picked up a book about a woman who had gone from obese to competing in fitness shows. The realization that hit her was simple: the only difference between them was habits. Not genetics, not circumstance. Habits. That single insight drove 150 pounds of weight loss in nine months and eventually became the philosophical core of everything Fitly AI does.

The shortest feedback loop in product development

Zoe is not just the co-founder of Fitly AI. She is its most demanding user. She tracks her workouts and meals in the app every day, and Brad, her husband and developer, watches that happen in real time. When something creates friction for Zoe, it gets fixed. No user interviews, no surveys. The feedback loop is a conversation across the dinner table.

Built for the day after a bad day

Zoe is a perfectionist. One missed day used to mean the whole week was written off. Gentle Mode was built to solve that: it tracks exact numbers in the background but only shows the user a percentage, enough awareness without the spiral. The pirate coaching personality works on the same principle. Humor lowers the stakes. Both features exist because Zoe needed them herself.

These moments matter because they show how lived experience, when taken seriously, becomes product logic.

The Quote from the Episode

Picture of Zoe Pineau with a quote from episode 158 of Women Disrupting Tech, which features an interview with her. The episode is titled 'How She Turned Fitness App Frustration into an AI Fitness Coach with Zoe Pineau'. The quote is “Your habits control your outcomes.”

"Your habits control your outcomes.”
— Zoe Pineau, co-founder of Fitly AI

Zoe said this in the context of her own weight loss journey, but it applies equally to how she built Fitly AI. The product exists because she took that principle seriously enough to remove every obstacle standing between a user and the habit they are trying to build.

If you know a woman who is looking to improve her fitness, tell her about the episode.


Zoe’s episode sits at the intersection of three patterns that keep appearing across Women Disrupting Tech conversations this season. Each one points to the same underlying shift: the founders gaining traction are the ones who make it easier for users to get results, not the ones who give them more to manage.

Removing friction is the new differentiator

Femke Delissen (Ep. 150) monitors elderly patients using WiFi signals instead of cameras or wearables, removing the friction of wearing a device entirely. Carmen van Vilsteren (Ep. 151) argues that a product fitting existing clinical workflows will always beat a technically superior but complex alternative. Zoe’s answer to the same problem is a single sentence replacing multiple screens. The specific context differs across these episodes. The logic is identical.

The shift from apps to agents

Rachel Gilley (Ep. 156) spent her episode explaining how brands need to show up when AI platforms answer questions, not just when users search. Zoe predicts that users will eventually manage fitness, finances, and scheduling through one preferred agent that coordinates specialized tools behind the scenes. Both guests are responding to the same structural change: the interface layer is moving from applications to conversation.

Founders are building faster with less

Marsha Goei (Ep. 149) validated her dating app concept using paper profiles, WhatsApp, and Excel before writing a line of code. Sabrina Nowicki (Ep. 153) prototyped in Figma and tested with real users before hiring engineers. Zoe compressed six years into one month using AI across development, design, and marketing. The pattern is consistent: separate validation from building, and use every available tool to close the gap between idea and product.

These trends matter because they are not isolated experiments. They are a signal about where the most effective founders are placing their bets.

Coming Up On Women Disrupting Tech

Maaike Steinebach has a specific image for what it takes to keep a fragmented industry moving in one direction: dog walking. Not the easy kind, the kind where you're holding five leashes at once, a startup, a government body, an investor, a healthcare provider, an insurer, and every one of them wants to go a different way.

That image comes from episode 159, where Maaike and Sophie van Dijk talk about building FemTech NL, the organization they co-founded to connect the more than 90 FemTech companies currently working in isolation across the Netherlands. The episode traces how a fragmented industry, one where labs, startups, hospitals, and investors rarely see each other's work, starts to move toward collaboration instead.

In this short clip, Maaike walks through what happens the moment one of those puppies pulls in a different direction, and why keeping all of them aligned takes more than good intentions.

What I Want to Leave You With

Most tools designed to help people change behavior fail at the moment they add more steps than the habit they are trying to build. Zoe's episode is essentially a fifty-minute proof of that idea.

What makes her story unusual is that the insight did not come from market research or competitor analysis. It came from standing in a store, reading a book, and realizing that the gap between where she was and where she wanted to be was not fixed by adding more. It was fixed by changing one thing at a time until the habit held.

That is also how Fitly AI was built. Not by adding features, but by asking what the minimum viable habit looks like and removing everything that gets in the way of it. The product reflects the person who built it, which is rarer than it sounds.

For founders, the question worth sitting with is this: how much of what you are building is actually serving the user, and how much of it is serving your assumptions about what a complete product should look like? Zoe spent six years on the first version of that answer.

About Zoe Pineau

Zoe Pineau is the co-founder and CMO of Fitly AI, a chat-based fitness and nutrition coaching platform based in Charlottetown, PEI, Canada. A certified personal trainer and nutritionist, she lost 150 pounds in nine months through macro tracking and went on to compete in bodybuilding. Her personal transformation is the foundation of everything Fitly AI does.

Before co-founding Fitly AI, Zoe spent six years building MyFit Suite alongside her husband, Brad. When users began gravitating toward conversational AI, the two rebuilt the product from scratch, this time with conversation as the interface rather than the feature.

Zoe has been featured in Oxygen Magazine and is the primary public face of Fitly AI. You can follow her on Instagram, TikTok, and connect with her on LinkedIn.


About Fitly AI

Fitly AI is a chat-first fitness and nutrition coaching platform available on iOS and web. Instead of navigating menus or searching food databases, users describe what they ate, snap a photo of their plate, or ask for a workout program in natural language. The AI handles the rest, including logging, tracking, and personalized coaching.

The platform combines a full macro and nutrition dashboard with a conversational AI coach that builds context over time. It tracks meals, workouts, water intake, weight, and personal notes, and adapts its advice based on what it knows about the user: their goals, injuries, preferences, and history. Coaching personalities are customizable, from a drill sergeant to a chef to a pirate, depending on what keeps the user engaged.

Fitly AI integrates with ChatGPT and Claude via Model Context Protocol, allowing users to update their fitness data through whichever AI assistant they prefer. The founding team sees this as part of a broader shift: away from standalone apps and toward specialized agents that work behind the scenes inside a single conversational interface.

Fitly AI was built by Pineau Labs and launched on June 18, 2026 at the Atlantic Venture Forum Showcase in Halifax. It is currently pre-seed and bootstrapped. You can learn more at fitly.chat.
