01 · THE CAREER
Every step taught me a different altitude of the same job: make the thing people need, then make the org that makes the thing.
Ad-tech SaaS: Voluum & Zeropark. Cut 45 scattered initiatives down to 4 core rebuilds and 6 strategic bets, set the group's market positioning, and led its product and AI transformation — while still shipping experimental products myself, on principle.
Turned feature factories into teams that own outcomes: product triads, a real user-research culture, separate strategies for both products. Time-to-value down 60%, team eNPS from 20 to 54 — and a promotion to CPO after 14 months.
Strategy consultancy run by practitioners who still practice. Workshops that end in decisions, then execution support — for Allegro, Betfan, Kuźniar Media, Valueships, Rohlig SUUS Logistics.
The parachute gig: pivoted a marketing agency into a SaaS for US home-service pros. Shipped v1, got the first 1,000 paying customers, built the activation engine, handed over.
Clarified the B2B2C Partners strategy into two product lines and shipped the Partners Portal from zero: retention up 12%, issue-resolution time cut ~5×. Led the product-practice transformation on the side.
Owned the calendar — where users spend 90% of their time. Built the area's 3-year strategy, cut lost jobs 6% for the key segment, and sold everyone on an engine rebuild with zero "immediate value" that unlocked everything after. First PM in Poland; hired 3 PMs and 2 designers.
Innovation arm of the world's biggest food delivery (2M daily users). White-label groceries engine built in a month, live in Talabat and Hungerstation in two, 20% of early restaurant customers converted to grocery delivery.
Co-built Netguru's product management practice. Click & collect for Żabka, a US insurtech, a Berlin catering app — alongside the future founder of Gorillas.
Started in the warehouse, got moved to planning, then built an Excel macro that planned the entire production line for me — components, forecasts, output. That was the day I realised I don't want to plan products. I want to build them.

02 · SIDE PROJECTS
Deep in the Claude ecosystem, always an experiment or two running. The current cast:
Your calendar says you're free. Your nervous system disagrees. Reality Check shows how loaded the coming weekends actually are — so you know whether to answer the kayaking invite with "of course!" or "how about mid-July?"
STATUS: SHIPPING · SAVING MY WEEKENDSOne shared space for a personal trainer and the person they coach — training plans, progress, and the small wins that get lost between gym sessions.
STATUS: IN THE GYM · REPS: COUNTINGAlways brewing. Built fast, validated faster — the same way I tell companies to do it, just with more coffee and two dogs supervising.
STATUS: BREWING · ETA: ONE WEEKEND03 · EDUCATION
Education always mattered to me — but too many programs are theory taught by people who left the field. I'm building the antidote.
"Interesting lecture" is a failing grade.
"I actually built something" — that's a pass.
— the whole idea behind the program

04 · WORK WITH ME
Beyond the day job, there are exactly two doors — pick by how much is on fire. Either way, the same beliefs apply:
A consultancy run by practitioners who still practice. We don't hand you a deck and leave — we facilitate your answer with your people, then stay to execute it.
ALLEGRO · BETFAN · KUŹNIAR MEDIA · VALUESHIPS · ROHLIG SUUS

Your Head of Product left, the roadmap is a rumour, and the board meeting is in three weeks. I parachute in.
DONE AT: OLLY OLLY (AGENCY → SAAS, FIRST 1,000 PAYING) · RAMP NETWORK
call me when it's messy.
THE CONSCIOUS NO'S → no roles where the strategy is fixed and I'm just there to execute · no slides-and-leave consulting · no organisations that don't want to be challenged · no micromanagement cultures
05 · SECOND OPINIONS
"A very down-to-earth CPO. What truly sets Piotr apart is his ability to balance high-level vision with pragmatic execution — empowering individuals to take ownership, always ready to support without micromanaging."
"I like their style — organised, professional, assertive, sharing knowledge in a way that's light but effective. They work a bit like therapists you resent for only asking questions. But asking is a craft."
"An astute product manager with an indisputable talent for setting his team up for success. He never shied away from reaching out to users through every channel he could find — and is never afraid to question the status quo."
