Company profile
researched Sep 2026Madbarz is a Zagreb-based fitness technology company whose main product is a mobile application for bodyweight (calisthenics/street workout) training. The app offers pre-built workouts, workout plans for all fitness levels, the ability to create custom routines from a library of more than 350 exercises, and video tutorials for each exercise. Completed sessions are logged into a history and converted into statistics covering activated muscle groups, calories burned, workout duration, repetitions and consistency, presented as graphs. Workouts range from about five minutes to one hour and can be performed without equipment, including without a pull-up or dip bar; saved routines can also be used offline, with results syncing once the device is back online.
Alongside training, Madbarz sells a nutrition product built around more than 65 whole-food recipes sorted into breakfast, lunch, dinner, side dishes, snacks and treats, plus 14 goal-oriented eating guidelines. Nutrition plans are split into two goals - building lean muscle and burning fat - with serving sizes tailored to each, and are positioned as requiring no calorie counting or advanced cooking skills. The company also runs a blog with workout, nutrition, education and user success-story content.
The Madbarz brand originated in 2013, when Luka Macner assembled a global online community centred on bodyweight training and then decided to build tools for that audience because no comparably focused product existed on the market. Work on the app concept began roughly a year before the company's first investment was announced, and the app was launched around mid-2015.
Founding story
The Madbarz brand was created in 2013 when Luka Macner gathered a global community around bodyweight training and subsequently decided to build products specifically for that community, as no comparable market offering existed. Development of the application concept started roughly a year before the first investment was announced in 2015, with Macner and Nikola Mratinić as co-founders.
Business model
Madbarz operates a freemium model: the core app is free to use indefinitely, while Madbarz Premium, a subscription sold inside the app and on the website, unlocks more than 45 workout plans, the nutrition guide, the "Me" statistics page and unlimited creation or saving of custom workouts. Premium is offered with a seven-day free trial at $59.99 per year, $24.99 per three months, or $299.99 as a one-time lifetime purchase, with subscriptions cancellable at any time and a 30-day refund policy (iOS purchases refundable only through Apple). Standalone nutrition guides - Build Muscle and Burn Fat - are sold as one-time purchases discounted from $14 to $9.80, unlocking an online nutrition platform; PDF products are not refundable once downloaded.
Revenue comes from consumer subscriptions to Madbarz Premium (annual, quarterly and lifetime tiers) purchased through the iOS and Android app stores or the madbarz.com website, plus one-time sales of nutrition guides and other digital products.
Traction
The app launched around mid-2015 and reported approximately 700,000 users by June 2016, with about 2,000 new registrations per day, more than two million workouts completed over the preceding year, an average in-app session of roughly 20 minutes, and about 50,000 weekly "respects" exchanged between users. By April 2018 the company was reported to have around one million users. Pre-launch it had over 190,000 Facebook fans and more than 40,000 people on its waiting list.
Latest developments
Madbarz was listed among the startups admitted to the Techstars London accelerator class announced in April 2018, with a three-month program and a demo day scheduled for September; at that time the app was reported to have about one million users. The company currently markets Madbarz Premium subscriptions and paid nutrition guides on its website.
▸Full profile — market position, technology, go-to-market, geography, history, risks & controversies
Market position
The company positions itself in the bodyweight-training segment of the fitness app market, which its co-founder described as young relative to running or gym apps that have existed for nearly a decade and count between 10 and 80 million users. Management said only a few competitors operate in bodyweight training and that none offered a complete solution combining workouts with additional content such as nutrition plans. Madbarz was one of 11 companies selected from more than 1,000 applications for the fifth class of Techstars London.
Focus on bodyweight training rather than gym or running use cases, combined with a bundle that includes structured workout plans, customizable routines from a large exercise library, detailed progress and muscle-activation analytics, video tutorials, offline access and an integrated nutrition guide - a combination the founders described as absent among the small number of competitors in the segment.
Technology
A hybrid mobile application released for multiple operating systems alongside a web training platform. Features include an exercise library of over 350 movements with high-quality video tutorials, muscle-activation tracking, calorie, duration and repetition analytics displayed as graphs, offline use of routines and saved workouts with later synchronization, and a social "respect" mechanic allowing users to endorse each other's workouts.
Go-to-market
The company built an audience first through a global bodyweight-training community and social media, reporting more than 190,000 Facebook fans and over 40,000 people on the app waiting list before launch, growing by roughly 400 sign-ups per day. Distribution is direct-to-consumer via app stores and the madbarz.com website, supported by content marketing through a blog covering workouts, nutrition and education, and by published user success stories. Accelerator participation (Zagreb Entrepreneurship Incubator, Techstars London) provided mentor networks and a route toward the U.S. market.
Consumers of all fitness levels interested in bodyweight and home training, from beginners through advanced street-workout practitioners, including people seeking fat loss, lean muscle gain or short workouts that fit a busy schedule. Programs are segmented by goal and audience, such as For Busy Men, For Busy Women, Home Transformation and 6 Pack Abs.
Geography
Headquartered in Zagreb, Croatia, with an international consumer user base; the company participated in the Techstars accelerator in London and cited access to the U.S. market as a reason for taking investment from Hungary-based Traction Tribe.
History
After starting as a bodyweight-training community in 2013, Madbarz went through the Zagreb Entrepreneurship Incubator (ZIP) program, where it met Hungarian fund Traction Tribe during an investor visit; the fund contacted the team and the first investment closed 25 days after initial contact, announced in 2015 with the startup valued at HRK 6.8 million. At that point the web training app had been in closed beta for about a month and a beta of the hybrid mobile app was being released to testers for three operating systems, while the company was recruiting a frontend developer. The app launched around mid-2015. In June 2016 the seven-person team was accepted into the fifth class of Techstars London, receiving $120,000 and running the program until 20 September 2016. In April 2018 Madbarz was again reported among Croatian startups admitted to Techstars London, alongside Memgraph.
Risks & controversies
Commentary published alongside the 2015 investment announcement questioned whether social media followings and waiting-list sign-ups constituted meaningful traction for a service that had not yet launched, noting that a large share of the Facebook likes originated from Mexico City. A local commenter also questioned the sequence of the company receiving investment and subsequently returning to an accelerator program.
