Product Marketing Course

Kateryna Litvynchuk, CEO at FitMe — the leading business within the Gismart ecosystem and a fast-growing Health & Fitness app globally. 6 years of experience scaling B2C mobile products across different consumer niches.

Over the last 3 years, focused on building FitMe into a lovemark brand for millions around the world.

Switched from tax consulting to product marketing after 5 years advising 45+ of Ukraine's largest businesses.

Ran 200+ A/B tests in 2.5 years with a 15%+ win rate.

Built 15 funnels that together generated nine-figure ARR.

Currently leads Product Marketing at FitMe, a subscription fitness app for any age and fitness level.

9+ years in product marketing working at the intersection of product, marketing, and analytics, building growth systems rather than isolated campaigns.

Scaled multiple digital products through full-funnel optimization — from acquisition to monetization and retention. Drives revenue growth via LTV, pricing strategies, and structured experimentation.

Started as the first marketing hire at MyGrowth; later led a new RnD product to Top-3 in Gismart portfolio. Concentrates on what actually drives revenue: funnels, monetization, and scalable growth mechanics.

Specialized in profitable web2web funnels - every funnel launched achieved unit economics.

Led cross-functional teams across product, UA, creative, and development and owned the full funnel cycle: creative, UA, monetization, analytics/attribution, payments.

Lectured at Superludi School and the Visa & PrivatBank entrepreneurship program.

Built a systematic, data-driven, and performance-based approach to developing web funnels. Relies on the following core mantras:

• Data holds all the answers - but only if you know how to ask the right questions.
• Small changes only bring small results.
• A poorly launched test is far better than no test at all.
• Data-driven doesn’t mean A/B testing everything.
• Scalability is a byproduct of logic, not luck.
• One change at a time

Has 4+ years in marketing, 3 of them in edtech. Managed seven-figure monthly budgets across Facebook, Google and Apple Search Ads. Built the Google Ads team and later the PMM team. Worked cross-functionally on both brand and performance initiatives.

Now leads product and growth at Spilio, an edutainment product. Works across web funnels, paywall and pricing experiments, and the analytics behind them. Responsible for building and improving product itself to enable business scale.

In Gismart Academy, Kate teaches how to know your users — from identifying your audience through Customer Personas and Jobs To Be Done to turning research into product decisions and messaging that different segments actually respond to.

Started her career in finance, then made the switch to marketing — and stayed. Has hands-on experience across media buying, creative production, and product marketing. Has a strong analytical mindset — every decision is backed by data.

Launched 5+ products on web-to-app funnels across different niches: entertainment, utilities, health & fitness, and lifestyle. Worked with both mobile apps and web products.
