Katia Fediunina

I'm Katia. I've personally run acquisition, product growth, positioning, lifecycle, and the economics underneath all of it. Four tabs, one person. I can see the whole growth system, find the real constraint, and fix it with a lean team. Pick the lens that matches what you're hiring for.

Marketing leader with 15+ years building and scaling consumer products.

I build growth systems across acquisition, positioning, product, content, PR, influencers, SEO, and lifecycle — with CAC/LTV discipline and strong cross-functional ownership.

I connect marketing, product, and operations into one growth system — not isolated campaigns.

Product-growth leader who finds what actually blocks growth.

I work at the intersection of product, marketing, analytics, and user behavior — improving activation, conversion, retention, monetization, and market fit.

I find the real constraint: positioning, activation, retention, monetization, or product friction. Then I fix it with the product team.

User acquisition with cohort logic, LTV, and payback discipline.

I have scaled paid acquisition across Meta, Google, TikTok, Apple Search Ads, and other channels — but I don't treat volume as success unless the economics work.

Performance with discipline: cohort logic, LTV, payback, and scalable acquisition — not vanity volume.

Senior growth and marketing support for early teams.

I help founders and teams diagnose growth constraints, sharpen positioning, structure GTM, and turn messy marketing problems into clear priorities and experiments.

Useful when you don't need another agency — you need senior judgment, structure, and a practical growth plan.

How I can help

Growth Diagnosis Sprint

For early teams with traction, but unclear growth constraints

+

I review your product, funnel, channels, positioning, metrics, and current assumptions to identify what is actually blocking growth.

Typical output

  • Growth constraint diagnosis
  • Funnel and channel review
  • CAC/LTV and payback logic
  • Priority growth hypotheses
  • 30/60/90-day action plan

Best for: Founders who know they need growth, but are not sure whether the problem is acquisition, positioning, product friction, monetization, or focus.

App Acquisition & Growth Strategy

For teams that want to understand app acquisition before scaling spend

+

I help define which channels are worth testing, what metrics matter, what needs to be tracked, and how to approach acquisition without burning budget blindly.

Typical output

  • Channel testing strategy
  • Measurement and analytics recommendations
  • Budget prioritization
  • Creative and audience hypotheses
  • CAC/LTV logic
  • First experiments roadmap

Best for: Consumer apps, marketplaces, subscription products, healthtech, edtech, and early mobile products.

GTM / Market Entry Sprint

For companies launching a new product, market, or geography

+

I help turn messy market context into a practical launch plan: ICP, positioning, local messaging, channel priorities, budget logic, and first experiments.

Typical output

  • Market and competitor research
  • ICP and demand validation
  • Positioning and messaging adaptation
  • Channel and budget prioritization
  • Launch roadmap

Best for: Teams entering Brazil, LATAM, Europe, or multilingual markets — especially consumer apps, marketplaces, subscriptions, edtech, and healthtech.

Product Growth & Funnel Sprint

For products where acquisition is not the only problem

+

I review the user journey to identify where activation, conversion, retention, monetization, or trust breaks down — and turn those insights into product and growth experiments.

Typical output

  • Activation and onboarding review
  • Conversion and retention friction map
  • User journey analysis
  • Experiment backlog
  • Product and marketing recommendations

Best for: Teams that suspect growth is blocked by UX, onboarding, positioning, monetization, lifecycle, or product-market fit.

Fractional Growth / Marketing Support

For teams that need senior growth direction before hiring full-time

+

I can support strategy, prioritization, team and agency guidance, experiment planning, and cross-functional alignment across marketing, product, analytics, sales, and operations.

Typical support

  • Weekly growth leadership support
  • Growth strategy and prioritization
  • Team or agency guidance
  • Experiment planning
  • Funnel and performance review
  • Product and marketing alignment

Best for: Founders and early teams that need experienced growth leadership without adding a permanent senior hire immediately.

AI / Growth Workflow Experiments

AI is part of how I work, not a separate offering. It lets one experienced operator cover ground that used to need a team: research, analysis, creative testing, reporting, and lightweight internal tools. I'm interested in projects where that covers a real problem.

  • AI-assisted research workflows
  • Marketing automation prototypes
  • Creative testing workflows
  • Competitor or market intelligence systems
  • Growth reporting or insight extraction
  • Lightweight internal tools for marketing teams

For the right project, I am open to a limited pilot, collaboration, or proof-of-concept format. It has to be useful, practical, and connected to a real business problem — not AI for the sake of AI.

Not sure what you need? Send me the context. I can usually tell after one conversation whether the problem is acquisition, positioning, product friction, monetization, or focus.

Let's talk

Deep in one thing, useful across many.

I go deep on growth economics: CAC, LTV, cohorts, payback. Around that core I work across product, positioning, lifecycle, content, PR, and operations. T-shaped on purpose.

Most growth problems aren't marketing problems.

They're positioning, product friction, or incentive problems. My job is to find the real constraint before spending budget on the wrong one.

Goals first, tactics second.

My favorite question is "why?" If the goal, the success metric, and the outcome aren't clear, execution is just noise.

I do a lot with a lean team.

I've built functions from scratch and run them without big headcount. I own outcomes, not just outputs, and I move across whatever needs to move.

AI as leverage, not decoration.

AI removes the grunt work so I spend my time on judgment and prioritization. It's why one experienced person can now cover ground that used to need a team. This site is one small example: I built it myself with AI.

Research & analysis with AI Ideation with AI Low-code prototypes Vibecoding / landing page experiments

Languages: Russian (native)  ·  English (C1+)  ·  Portuguese (C1+)  ·  Spanish (working)

I'm selective about where I go next. I do my best work when these line up.

Stage & product

  • Early or scaling digital-product companies: marketplaces, subscriptions, consumer apps, healthtech, edtech, AI.
  • Products I can stand behind. Real outcomes for users, not physical goods or hype.
  • A real product and team, credible enough to commit to for two to three years.

The problem & the role

  • Genuine ownership of a growth system, not a single channel to execute.
  • 0→1 or market expansion, where range and judgment matter more than headcount.
  • A lean setup where being T-shaped is an advantage, not a rounding error.

Market & language edge

  • LATAM, Brazil, or Europe, where Portuguese, Spanish, and Russian plus localization are an asset.
  • International, flat, direct teams. Outcomes-led, not heavy top-down.

Open to full-time, fractional, and focused consulting. Remote-first, Western European time (Lisbon, London).

This page is a prototype I built and shipped myself using AI. I treat landing pages and growth experiments the same way: build it, ship it, test it, learn.
