Chernihiv — a city with a unique combination of ChNTU's engineering tradition, an active Chernihiv IT Cluster, and businesses recovering after war trials. I'm Oleksandr Filyuk, with 15+ years of practice in product strategy and 130+ delivered projects. I see how Chernihiv teams — from startups near Mahistratska to manufacturing companies on the outskirts of Desnyanskyi district — face the same problem: plenty of energy and ideas, but no clear system for converting them into stable MRR growth. Strategy is the missing layer.
Product strategy is not a deck with beautiful slides. It's the company's operating system: it defines who you build for (ICP), what job your product does (JTBD), how you win competitive battles, and which metrics measure progress. Without this system, the dev team builds features 'on request,' marketing wastes budget on irrelevant audiences, and the CEO makes decisions based on intuition instead of data. I build strategy that combines the JTBD framework, North Star metric, AARRR funnel, and RICE prioritization into a single living artifact your team uses daily.
My process begins with deep context immersion. The first 5-7 days I conduct 15-20 interviews: with your team (CEO, PM, design, engineering, sales), with 8-10 customers in different segments, with 3-5 market experts. I use JTBD methodology to uncover real purchase motives, which often differ from what the sales team reports. For Chernihiv B2B products this matters especially: the Ukrainian market is small, an ICP mistake costs months of wasted investment and runway.
Next I build the SAM/TAM/SOM model, analyze competitive landscape, form positioning hypotheses. I use RICE for feature prioritization and ICE for early-stage products. Each hypothesis goes through Sean Ellis test and retention analysis. The resulting roadmap is laid out across 3-6-12 month horizons with quarterly OKRs tied to P&L. I don't leave the team alone with the document — I run workshops in Chernihiv (center, Heroes Alley, or coworking near Krasna Square) and online, so every team member understands strategy at decision level, not just slide memorization.
Chernihiv region is a hub with a strong agricultural sector, historical tourism (Chernihiv Detinets, Boldyna Hora, Kotsiubynskyi Park), wood processing, and musical instrument manufacturing. Each of these niches has its strategic logic. For agritech I build models accounting for seasonality and the long farmer decision cycle, for tourism — strategies combining international flow (through EU programs) with local loyalty, for manufacturing companies — digital transformation through DTC e-commerce reaching new customer segments directly.
A separate category is startups in Chernihiv IT Cluster. I've worked with teams building SaaS, marketplaces, B2B services for Western clients. For them product strategy is a survival question: small runway, limited team, need to find PMF fast. I shorten the strategic cycle to 3 weeks and focus the team on 1-2 key hypotheses simultaneously. The third category is businesses recovering from war damage. Here strategy starts with asset audit and search for new revenue models that account for shifted consumer behavior and supply chain realities.
My 'toolkit' of strategic instruments is built up over 15 years and 130+ projects. The base layer — JTBD maps, ICP documents, North Star metric, AARRR funnel, SAM/TAM/SOM model. On top — prioritization frameworks RICE/ICE for backlog management, OKRs as execution operating system, HEART for UX metrics. For analytics I work with GA4, Mixpanel, Amplitude, FullStory, Hotjar — choosing the stack for your stage and budget carefully. If analytics is poorly configured (and in 70% of Chernihiv teams this is the case), I do an audit and tracking plan as part of strategy.
Separately I bring unit economics metrics: LTV, CAC, payback period, MRR, ARR, churn. For Ukrainian startups it's critical to see early whether unit economics work before scaling marketing. I help build a P&L model and 18-month financial forecast that allow the CEO to make decisions about hiring, investments, new markets based on numbers rather than fear or enthusiasm. All artifacts live in your Notion or Miro — I don't lock knowledge behind a paywall, I transfer it to the team for ongoing use.
Chernihiv today is a region with a paradoxical combination of challenges and opportunities. On one hand — war consequences, talent outflow, limited capital access. On the other — a tight professional community through Chernihiv IT Cluster, low talent competition compared to Kyiv, the ability to build products for global markets with less expensive operational base. This window of opportunity won't stay open forever — companies investing in strategy today will have a structural advantage over those waiting for 'better times' in 2-3 years.
I see my role as a partner who helps Chernihiv business not just survive but grow on this window. Learn more about my product strategy service or related areas: conversion optimization in Chernihiv.
