Award-winning Kraków performance agency with medical marketing know-how but no dental-only service
About Harbingers
Harbingers is a marketing agency in Kraków, registered as Harbingers sp. z o.o., with offices on the fifth floor at Mosiężnicza 3. It has a wide offer: SEO and GEO, paid media across Google, Meta, LinkedIn, Microsoft, TikTok and Allegro, content marketing, social media, branding, web analytics and AI-driven automation. Most of its public track record comes from e-commerce, and the company works as a business advisor that in some cases ties its fees to growth in client revenue.
The business is run by CEO Kornel Dulęba with managing partners Filip Krasiński and Piotr Kwinta. The team started as a handful of people, grew more than tenfold and counted 80 specialists in 2022, drawing on over 15 years in digital work. The company has changed headquarters three times, most recently in 2020. The current limited company dates from 2017.
There is no page aimed only at dentists. Healthcare relevance comes from a health and beauty industry page, a specialist-sectors page that includes healthcare among the fields served, and a set of blog articles on medical marketing. One of those articles explains paid campaigns for medical providers: long-tail keywords, location targeting, call and location extensions, and conversion goals such as booked visits. It cites the Endodentist clinic as an example of district-level targeting and summarises the 2023 Polish rules that stop doctors and clinics from comparing themselves with rivals, running promotions or promising treatment results. That regulatory awareness matters for clinics, because generic ad copy can easily break those limits.
For specialist sectors the agency uses a four-stage method: analysis and interviews, strategy with agreed KPIs, implementation, then reporting and refinement. Services for these clients include local SEO, expert articles, lead-capture landing pages, UX review and email automation linked to CRM tools. A blog interview with the head of Kliniki.pl, a Polish medical booking marketplace, explores AI analysis of clinic phone calls, though Kliniki.pl is not named as a client.
Evidence of results sits mostly outside dentistry. Named partners include Castorama since 2019, OKNOPLAST, Neonet, Capgemini, Empik and Kärcher. The agency has 98 awards and nominations, among them a 2021 Global Content Award, a European Search Awards win in 2023, Gazele Biznesu listings in 2022 and 2024, and the EMEA main prize at the 2025 Google Ads Impact Awards. Google Partner status was confirmed in 2024. It has a 4.7 Google rating from 67 reviews.
This agency fits larger Polish clinics, multi-site dental groups or dental product retailers that want a big team with analytics and paid-media depth. A single-chair practice wanting a packaged dental SEO plan will find no published dental pricing and no named dental clients.
