We are not building an agency. We are building an ecosystem of solutions
Semidea Group is more than just a holding of three brands – it is a deliberate ecosystem where each company operates like a specialized organ within a single organism. Each brand has its specific role, its own tools, and unique expertise, but they are all united by one goal: the real growth of your business.
We are not interested in building an agency that does “everything for everyone” – instead, we have created three precisely specialized brands that solve specific business challenges. When you need comprehensive marketing support, we direct you to Semidea.pl. When your problem is a lack of hot leads – LeadRadar.pl has a ready solution. Do you run a cinema, theater, or event center? EventSell.pl are experts who have known this industry inside out for 20 years.
Together, we create a coherent system that works effectively – without overlapping roles, without competence chaos. Only clearly defined specializations that complement each other.


Semidea.pl – comprehensive marketing partner
For whom: B2B, B2C, e-commerce companies, and businesses planning international expansion that need a strategic partner at every stage of development.
What we do: Comprehensive 360° marketing – from strategy, through performance campaigns (Google Ads, Meta Ads, LinkedIn), SEO, and content marketing, to creating websites and online stores. But that is not all – our key differentiator is the development of distribution in Poland and abroad. We help companies scale into markets such as Germany, France, Norway, Spain, or the USA.


We are not just another agency that only executes tasks. We act like a true business partner – proactively, with initiative, and with an emphasis on measurable results instead of empty promises. The “results, not promises” philosophy is not a slogan; it is the way we approach every project. We hold official partnerships with Google, Meta, and Allegro Ads, which gives us access to the latest tools and technical support.
We start with a free marketing audit, which demonstrates our analytical competencies even before a contract is signed. Then, we build a data-driven strategy, execute campaigns, and provide cyclical optimization – in a loop of continuous improvement.
When to choose Semidea.pl:
- You need comprehensive marketing support from strategy to execution
- You want to scale your business into foreign markets
- You are looking for a partner who will proactively advise instead of just waiting for a brief
- You care about transparency, analytics, and measurable results (ROI, lead cost, conversions)


LeadRadar.pl – fabryka gorących leadów
For whom: B2B and B2C companies that are tired of wasting salespeople’s time on cold calls and want a predictable customer acquisition system. Ideal for law firms, manufacturers, real estate agencies, training companies, aesthetic medicine, insurance, or the RES industry.
What we do: We deliver 100% exclusive hot B2B and B2C leads. This is not about reselling contacts from a database – these are precisely generated inquiries from individuals actively seeking your service right now. Every lead goes only to you, never to the competition. No more racing for the same contact.
It does not end with providing a contact – we put a proprietary CRM system in your hands that organizes leads, automates notifications (so you call within minutes of an inquiry), and learns from your successes thanks to Conversion API. The system knows which leads resulted in a sale and automatically looks for similar profiles.
Why LeadRadar: We eliminate randomness. Instead of shooting blindly with a broad branding campaign, we precisely target individuals at the moment of their purchasing decision. We utilize paid social (Facebook, Instagram, LinkedIn), Google Ads, SEO, B2B cold mailing, conversion-optimized landing pages, and retargeting that recovers lost sales opportunities.
You pay for the effect – for verified data, not for “reach” or “likes”. Each lead is someone who filled out a form, left a phone number, and expressed specific interest in your offer.


When to choose LeadRadar.pl:
- Your sales team is wasting time on empty calls and low conversion is frustrating you
- You want a predictable customer acquisition system, not random sales spikes
- You need territorial exclusivity for leads (no competition for the same contact)
- You care about full transparency – you see exactly how much each lead cost and which channel generates contracts
EventSell.pl – cinema marketing experts
For whom: Cinemas, theaters, sports and recreation centers, and event centers that want to fill their halls, increase attendance, and effectively promote special events. Ideal for multiplexes, arthouse cinemas, drive-in cinemas, and cultural facilities.
What we do: Tailor – made marketing for the entertainment industry. Our team consists of people who have worked in cinemas since 2000 – from managing chains (Silver Screen, Multikino, OH KINO) and C – level marketing, to selling popcorn behind the counter. We know this industry inside out because we have been a part of it ourselves.


We create websites for cinemas with showtime integration and ticket sales systems, publish showtimes in Google search results (allowing viewers to find screenings in seconds), run Google Ads, Meta Ads, and TikTok Ads campaigns tailored to the specifics of film premieres, optimize SEO for local events, and build social media engagement.
But it is not just about movie tickets – we help cinemas leverage the full potential of their space: birthdays, corporate events, hall rentals, organized groups (schools, kindergartens), and special screenings. Through 3D virtual tours, we showcase the interiors of facilities, which increases interest in rentals.
When to choose EventSell.pl:
- You run a cinema, theater, sports center, or event venue
- You want to fill your venues and increase attendance without wasting your budget
- You need specialists who understand the specifics of the entertainment industry (you do not have to explain to us what KDM or RPH is)
- You are looking for comprehensive solutions: from a website to advertising campaigns and virtual tours
