About
Adrian Brzenska
16 years in sales, an agency of his own, and one focus: what happens to your clients after the sale.

- Background
- 16 years in sales. From €500 one-off deals to six-figure ARR, from new business to account management. Plus a performance marketing agency of his own for boutique fashion labels: starting at around €500 a month per client, up to €6,000 for individual clients.
- What stuck
- Revenue is rarely won or lost at the lead. It's decided afterwards: whether the promise from the sales call holds up day to day, whether the client sees early proof, and whether they stay. And whether a business takes on the clients that actually fit it.
- How the work gets done
- The clearest picture comes from watching the actual work, not from a questionnaire. BiasGap makes that observation measurable and covers the breadth. Depth and context come from conversations with you, your clients and your team.
- What you can expect
- Direct contact, no sales team in between. A clear assessment, stated plainly and specific enough to act on. If everything after the sale already works for you, you'll hear that too.
