Nerds.family

Co-founder, Chief of Product & Psychometrics EdTech & Talent nerds.family

Nerds.family is a workforce development platform I co-founded with Oskar Lakner (CEO), Dorota Piekarska (CMO), and Marcin Ostrowski (CTO). We build practice-based academies where people entering or transitioning into tech careers learn by doing real work — not by sitting through lectures or collecting certificates.

The Academy 360 Model

We call our approach Academy 360 — a full-cycle model that connects companies, mentors, and learners through hands-on academies designed to grow talent pipelines, not just train individuals.

Participants work through six sprints over two to four months, building a fully functional application independently with mentor support. Tasks are tailored to individual strengths and weaknesses — each decision affects what comes next. Both individual and team work are simulated. By the end, participants have a deployed, shareable product they built themselves. All academies run in English.

The model is built on a simple conviction: skills are proven through real work, not declared on paper. We critique traditional bootcamps and CV-filtering because they optimize for credentials over capability. Our platform matches trained candidates with employers based on demonstrated competencies, shared values, and actual work output.

Relativity Partnership

Our flagship partnership is with Relativity, the legal technology company. Nerds.family powers the Ascent Academies phase of Relativity’s Relevate workforce development program — delivering self-paced, globally accessible academies across three career tracks: Engineering, Product Management, and Customer Success. Each cohort runs 20–30 participants through three to four months of free, practice-based training with legal data intelligence woven throughout.

My Role

I lead product strategy and bring the behavioral science lens to how we design learning experiences, assess participant progress, and match talent to employers. The psychometric thinking shows up everywhere — in how we structure adaptive task sequences, how we measure skill acquisition, and how we define “fit” in ways that go beyond resumes.

The Team

We’re a small team based primarily in Gdansk and Krakow — developers, educators, and one psychometrician who keeps asking whether we’re actually measuring what we think we’re measuring.

If you’re building a talent pipeline or rethinking how your organization grows capability, reach out. I’ll tell you honestly whether Academy 360 fits.
