KB&B

What KB&B does

KB&B is a Hamburg-based, privately held marketing agency founded in 1999 that operates exclusively in the family and children marketing vertical across the DACH region (Germany, Austria, Switzerland). The company delivers an integrated service offering organized into nine specialized units — Family Strategy, Family Facts, Family Creation, Family Digital, Family Social Media, Family Audio, Family Media, Family Education, and Family Sales — covering research, strategy, creative production, and multi-channel activation for brand clients targeting families with children. Its customer base spans 100+ brand clients across FMCG, toys, media, pharma, tourism, gaming, and government, including Deutsche Bahn, PLAYMOBIL, SONY Music/Europa, Ravensburger, DMK Group, Tessloff Verlag, ROFU Kinderland, and Super RTL.

The company's core technology assets are its proprietary research and media platforms. FACT FAMILY is an exclusive research panel with 30,000+ participating family members that enables direct child surveying — a rare capability in the DACH region due to regulatory constraints on child research — paired with FACT INSIGHTS, an AI-powered analysis platform that performs automatic topic and sentiment recognition across 50+ languages. FAMILY PULSE, developed with ROFU Kinderland, analyzes 70,000+ children's birthday party boxes to produce a proprietary BrandScore. The HEAROOZ podcast network reaches 248K-300K+ monthly downloads across 24+ series with Top-5 Kids-Chart placements. StoryWonder is a generative-AI storytelling platform that transforms licensed brand worlds (PLAYMOBIL, WAS IST WAS) into personalized audio adventures where children become protagonists, with 50,000+ installations and a 4.4-star rating. Owned media brands (miniLOK, LeseLOK, familie&co, baby&co, PapaBlogs, Kinderzeit) provide direct audience access to children, mothers, fathers, and educators, generating 29M+ annual social reach and 1M+ monthly reach without intermediaries.

KB&B generates revenue through three streams: project-based marketing consulting and strategy services across its nine service units, media sales across its owned brand portfolio, and creative production services. The company uses a consultative B2B go-to-market anchored by a free 30-minute strategy session for prospect qualification, followed by project engagements. International expansion is enabled through The League network of partner agencies in London, Madrid, Paris, and Milan. The agency is founder-owned by Rolf Kosakowski (Managing Director/Owner), with Lennart Kosakowski as COO and a specialist management team across units; no external investment or parent company is disclosed.

Recent moves6 records

Expansion highlights6 records

Broad incumbents

• UFA GmbH (Bertelsmann): Major German production house behind children's brands such as Bibi Blocksberg and Benjamin Blümchen. Operates in the kids/family content and brand world space that KB&B services as a marketing partner.
• Super RTL / TOGGO (RTL Group): Germany's leading children's TV broadcaster and digital kids brand (TOGGO), part of RTL Group. Existing KB&B client; competing vertically integrated kids-marketing and content proposition.
• Scholz & Friends: Major German creative agency group with family, kids and youth marketing work (e.g. for Ferrero, brand-world campaigns). Overlaps with KB&B in family creative campaigns but competes from a generalist platform.
• Mediaplus (Serviceplan Group): Largest independent German media agency, part of Serviceplan Group. Comparable in media planning capabilities but offers broad-portfolio services rather than KB&B's exclusive family specialization.

Direct peers

• Dubit Limited: UK-based digital agency and research firm specializing in kids, tweens and family audiences across digital platforms and gaming. Direct international peer for KB&B's Family Digital and Family Facts services.
• The Insights Family (Kinder, Jugend & Familie insights): Germany-based market research firm specializing in kids, youth and family panels across multiple countries. Direct peer to KB&B's Family Facts unit and FACT FAMILY panel, competing for the same brand-research budgets in DACH and internationally.
• SuperAwesome (Epic Games): SuperAwesome is the leading kidtech platform for COPPA/GDPR-compliant advertising, engagement and consent. It is the most direct competitor to KB&B's child-safe digital and audio stack and is already a documented partner on Roblox under-13 bookings.
• EDEL Kids (Edel AG): German family-and-kids audio label and brand management business, including podcast and music for children. Directly comparable to KB&B's HEAROOZ audio and StoryWonder personalized content offerings.
• Studio 100 Media: European family and kids entertainment company (Maya the Bee, Heidi) with brand management, licensing and media operations. Overlaps with KB&B's brand-world development for PLAYMOBIL-style IPs and family marketing services.

Emerging players

• Kind und Konsum (Kids & Consumption consultancy): Munich-based specialist consultancy advising brands on children as consumers. Smaller-scale consulting peer with overlapping family marketing expertise but without KB&B's owned-media scale.
