I start with an audit of the founder's vision, market and competitor analysis, formulate ICP and JTBD hypotheses, calculate SAM/TAM/SOM, and lock in a North Star metric with a tree of supporting metrics. Then I build a 6-12 month roadmap prioritized via RICE/ICE, tie it to OKRs and unit economics. You receive all artifacts in Notion or Confluence and can hand them to your team without me.
I combine qualitative JTBD interviews, the Sean Ellis test, GA4/Mixpanel/Amplitude analytics, and cohort retention analysis. If 40%+ of users say they would be very disappointed without the product and D30 retention flattens, that signals PMF. Until then I do not recommend scaling marketing, because it only accelerates churn.
Personas describe who your user is, while JTBD shows why they hire your product in a specific situation. This makes product decisions far sharper: you see real competitors (sometimes it is Excel or nothing), understand triggers, barriers, and success criteria. Across 130+ projects, JTBD framing helped me find non-obvious segments that delivered most of the revenue. More on the product strategy page.
OKRs bridge the North Star and the team's daily work. I write 3-5 quarterly Objectives, attach Key Results through AARRR metrics, validate ambition (60-70% achievement target), and set a weekly check-in cadence. This frees the founder from micromanagement and gives the Chernivtsi team transparent rules of the game. Without OKRs, strategy turns into wishful thinking.
I use RICE (Reach, Impact, Confidence, Effort) for large bets and ICE for fast experiments. Each idea gets a score, and we discuss assumptions in the Confidence column, where most team disagreements actually live. After prioritization the backlog is split into Now/Next/Later and tied to OKRs. The endless CEO-versus-PM debates disappear.
Yes. I build a P&L model in Google Sheets with MRR, ARR, CAC, LTV, payback period, gross margin, and churn. The model is sensitive to scenarios: you can see how a 10% price change or a 1.5 pp churn reduction affects cash runway. For SaaS teams from Chernivtsi IT Cluster this often becomes the key argument with investors or the board.
A standard engagement is 6-10 weeks: 2 weeks of research (interviews, data, market), 2 weeks of synthesis (ICP, JTBD, North Star), 2-3 weeks of planning (OKRs, roadmap, P&L), and 1-2 weeks of validation with the team. For early-stage startups I run a 3-week sprint format. We always lock scope in a kick-off document to prevent unjustified scope creep.
Common situation at early stages. I can act as fractional CPO 2-3 days a week: running the backlog, rituals, and team communication while you hire a PM. In parallel I help with hiring: writing the role profile, running case interviews, and onboarding the new hire into all artifacts. This way the strategy does not die the day I leave the project.
For Chernivtsi IT Cluster teams I recommend a beachhead model: one segment in one country where the ICP feels the pain most sharply. I help with customer development, positioning localization, channel selection (often Product Hunt, niche communities, outbound), and the legal structure for accepting payments. I cover this in depth as part of product strategy.
Chernivtsi is a natural hub for cross-border trade. I help design products that account for EU VAT and customs nuances, multicurrency (UAH/EUR/RON/MDL), copy localization into 3-4 languages, and integrations with Nova Post and Romanian carriers. Strategy splits B2C tourists from small B2B in border towns. The conversion side I cover in more detail in conversion optimization in Chernivtsi.
Yes, and it is one of my favorite segments. For Bukovyna winemakers I have built strategies for DTC subscriptions, wine clubs, and tourism routes through vineyards. For agritech I have helped with crop monitoring platforms and marketplaces between farmers and Chernivtsi or Lviv HoReCa. The key in every case is the JTBD of the grower or farmer, not trendy AI features. Strategy disciplines the product around real value.
Medtech in Chernivtsi is a blend of Bukovyna Medical's academic expertise and technical teams. I help validate the clinical hypothesis, plan pilots with clinics in the Shevchenkivskyi district, and ensure GDPR and Ukrainian health-data compliance. Strategy matters even more here because the sales cycle is long and an ICP mistake costs 12-18 months. I usually pair this with conversion optimization for the clinic sales funnel.

Chernivtsi is a city of around 265 thousand people with Austro-Hungarian heritage and UNESCO status. It uniquely blends the academic tradition of Yuriy Fedkovych Chernivtsi National University, the medical expertise of Bukovyna State Medical University, the technological energy of Chernivtsi IT Cluster, and a strong entrepreneurial spirit in Bukovyna winemaking, gastronomy, tourism on Kobylianska, and cross-border trade with Romania and Moldova. This makes product strategy in Chernivtsi specific: teams mix global ambitions with very local context, and template frameworks do not work here. I am Oleksandr Filyuk, with 15+ years and 130+ products behind me, and I build strategies that respect the reality of Shevchenkivskyi and Pershotravnevyi districts.
My process is built around three artifacts that stand the test of time: ICP, a North Star metric, and an OKR rhythm. I start with deep JTBD interviews, often run in cafes on Turetska or Soborna, because in-person conversations reveal nuances that Zoom misses. Then I size SAM/TAM/SOM against real data, not marketing slides. On that foundation a North Star metric is born: a single metric that correlates with long-term user and business value. I cross-check it through the AARRR funnel and HEART framework to make sure we are not optimizing what is easy to measure but what truly matters.
For prioritization I apply RICE at strategic level and ICE for tactical experiments. For hypotheses, JTBD statements and the Sean Ellis test. For analytics, GA4, Mixpanel, Amplitude, and Hotjar, with a focus on cohort retention and a metric tree. For unit economics I build a P&L model with MRR, ARR, churn, LTV, CAC, and payback period. For the roadmap I prefer Now/Next/Later over rigid quarterly plans because for Chernivtsi IT Cluster teams and cross-border businesses flexibility beats the illusion of predictability. The whole system snaps into OKRs and weekly team rituals, giving transparency to the founder and freedom to the product manager.
Over years of practice in Chernivtsi I have built up four strong segments. First, Chernivtsi IT Cluster startups, mostly SaaS and dev-tools aiming at global markets, where strategy focuses on beachhead, customer development, and the right first market. Second, DTC projects in Bukovyna winemaking, where I help with subscriptions, wine clubs, and tourism-product fusion at the vineyards. Third, cross-border e-commerce aimed at Romania and Moldova with multicurrency and EU logistics. Fourth, medtech around Bukovyna State Medical University, where strategy often saves teams from 12-18 months with the wrong ICP. I cover each segment in more depth in case studies and within product strategy.
Founders in Chernivtsi often ask where to start: strategy or funnel optimization. My answer is simple. Without a clear PMF and ICP, no landing-page optimization will save you, you will just burn traffic faster. Product strategy answers the question of what to do and why, while conversion optimization in Chernivtsi answers how to do it better within the existing product. At maturity the two services work in tandem: strategy sets the North Star, the CRO team runs tactical A/B tests and improves AARRR metrics. I often run both tracks in parallel for the same client.
The first step is a free 45-minute session where we discuss your product context, current metrics, team challenges, and whether I am the right person for your stage at all. If yes, I prepare a short proposal with three engagement scenarios: a 2-week express audit, a full 6-10 week strategy cycle, or fractional CPO for 3-6 months. I work online and offline in Chernivtsi, from an office near the Town Hall to quiet cafes on pedestrian Kobylianska. If you are a founder in Shevchenkivskyi or Pershotravnevyi district, or you lead a team in Chernivtsi IT Cluster and look for someone who can own product strategy without fluff, get in touch and let's talk.
