WHY I BUILT DISCOVERY STACK
SEO is degrading as the primary discovery channel. B2B companies have a roughly ten-year window — 2026–2036 — to build durable discovery positions before AI ads get expensive. Discovery Stack is the framework that helps them do it.
In 2024–2025 I ran B2B sales consulting from karoltabis.com. I was suffocating — a market flooded with paid ads, BOFu categories dominated by entrenched brands. In 2025 I decided: build my own product. That is how TrenujHandlowca was born.
The classic SEO playbook was not enough for TH growth. I started research — forty articles in April–May 2026, first framework drafts, validation on my own case. On May 26, 2026 I formalized the pivot: from B2B sales consulting to Discovery Stack thought leadership + implementation program.
Why this timing: the AI Overview era is just starting to collapse the classic SEO funnel. Many companies are 2–3 years behind the leading edge in GEO adoption. I bring an unusual profile: founder-builder with skin in the game, GEO/SEO operator, twenty years of B2B sales in the background — tested first in a Polish market that had no playbook to copy.
FIVE PRINCIPLES I HOLD EVEN AT THE COST OF SALES
PRINCIPLE · 01
TRANSPARENCY IN NUMBERS
I publish TrenujHandlowca baseline openly — positive or negative. Competitors lie with numbers. I do not.
PRINCIPLE · 02
ANTI-BUZZWORD
No "AI revolution," "10x growth hacks," or "synergistic platforms." Concrete framework + concrete components.
PRINCIPLE · 03
RESEARCH-BACKED CLAIMS
Every claim with evidence. Minimum five research citations per essay.
PRINCIPLE · 04
SKIN IN THE GAME
I built Discovery Stack for myself (TrenujHandlowca) before selling it to external clients.
PRINCIPLE · 05
LIMIT: 3 COMPANIES PER YEAR
Scarcity is not marketing. Twelve weeks of 1:1 work requires calendar capacity.
ONE CROSS-PLATFORM ENTITY
Schema.org Person linked cross-domain via sameAs. AI recognizes me as one entity across platforms — Discovery Stack, TrenujHandlowca, karoltabis.com, ORCID, GitHub. That is not decoration. It is an operational component of the stack.
