AdBrainiacs

What AdBrainiacs does

AdBrainiacs is a digital marketing agency operating as a sole proprietorship registered in Łódź, Poland, and founded by Paweł Sierpowski. The firm specializes in full-funnel growth management for e-commerce brands, integrating Meta Ads (Facebook and Instagram), Google Ads (Search, Display, Performance Max), and Klaviyo email automation as a unified system rather than siloed channels. Its core differentiator is the proprietary Predictable Growth Blueprint — a 4-phase methodology comprising Deep Research, Scientific Testing, Stabilization, and Precision Scale — that prioritizes 3-5 days of consistent ROAS monitoring before increasing budgets by 20-30% every 3-5 days via a Safe-Scale Protocol.

The agency's technology stack is methodology-driven rather than platform-driven: it relies on the Variable Isolation Protocol for rapid creative testing (15-20 variations, 24-48 hour kill criteria), daily monitoring of seven named performance metrics, and partner-certified integrations with Google, Meta, and Klaviyo. Reported operational scale includes $5M+ in cumulative ad spend managed, 1,000+ campaigns executed, 16 countries served across 4 continents, and an average client contract length of 12+ months despite the absence of long-term contract requirements. Documented case-study outcomes include 7x revenue growth and 5.3x ROAS for PurelyB, 9x peak ROAS for a premium beauty brand, 300% revenue growth in under a year for a portable camping brand, and ~€10k in Black Friday sales from under €2k ad spend for a Polish language-learning platform.

Commercially, AdBrainiacs operates a direct-to-consumer agency model with no intermediaries, resellers, or marketplace listings. Client acquisition runs through a free 30-minute strategy audit booked via Calendly, with the founder providing direct strategic access throughout engagements. Pricing is not publicly disclosed but is structured around ongoing management fees consistent with retainer-based managed services. The company is founder-owned and bootstrapped, with no external investors, parent entities, or public listing, and headcount remains at 1-10 employees — positioning AdBrainiacs as a boutique fractional-CMO operation rather than a scaled agency.
