500 USD Launch of marketing for mobile application
App Store Optimization (ASO)
Marketing launch of the mobile application Hava TV — a case study on how we brought a product to market that was only 50% ready, without a team and without a structured marketing plan.
A team was formed from scratch, a launch strategy was developed, and traffic was directed to cost-effective GEOs. Through a combination of targeted advertising, organic reach, and SEO landing pages, the project gained its first users and real traffic even before the full release.
… The result — 88,481 visits to the landing pages and over 20,000 app installations through advertising and organic reach.
The case demonstrates how to launch digital products quickly, intelligently, and with a focus on scaling, even when the product is still "in progress."

400 USD As a nutritionist, I received 32 sales with an average check of $100 per month.
Social Media Advertising
Targeted advertising for a nutritionist - a case study on how we launched sales without a blog, warming up, and daily content. Only a clear offer, lead form, and properly assembled funnel.
In a month, the advertising brought in 186 applications at $2.2 each, from which the client received 32 sales with an average check of $100. We proved that even in a competitive niche of expert services, Instagram can sell consistently if you build a system rather than "content for the sake of content."

500 USD As a security agency from Latvia, it received 84 contracts in 1 month.
Social Media Advertising
Targeted advertising for the security agency SP Legion (Latvia) - a case study on how in 1 month we built a lead generation system that brought in 114 applications at €0.71 and 84 annual contracts.
Through deep segmentation of the target audience, separate offers and creatives for each type of client (homes, small and large businesses), we transformed chaotic advertising attempts into a stable, predictable flow of clients. Without "shooting in the dark," with clear logic and a focus on contracts, not just applications.
… This case is about systematic targeting that truly sells and scales.

1000 USD Complex marketing for TIVA Pharm
Contextual Advertising
Comprehensive marketing for TIVA Pharm — a case about how we transformed a large e-commerce with over 50,000 items and constant advertising bans into a stable, manageable sales system.
We structured the marketing so that the business no longer depended on Google Ads: we launched email funnels, organized analytics, rebranded, built safe advertising for "white" products, and implemented advertorial strategies. As a result — growth in LTV, transparent ROI, and stability without the daily fear of bans.

447 USD Case. Launching an online accounting school from scratch.
Social Media Marketing (SMM)
About the project
There was an idea to launch a full-fledged online school for accountants, both for beginners and for active accountants, for professional development and learning new professions in various fields. After completing the courses, students can work for European companies, both offline and remotely online.
The owner of the school had practical experience conducting courses, but at another school, as a speaker.
…
Having a lot of experience and practice in conducting courses, the goal was to create her own online accounting school, which she approached me for.
Initial data
There was only an idea. There was absolutely nothing for the launch. No numbers, websites, pages, etc.
Action plan
After thoroughly analyzing the market, competitors, target audience, etc., we decided to conduct the first launch through a series of free live broadcasts with 4 introductory lessons on accounting for beginners, and in the last lesson, sell the main product - an advanced accounting course with an average check of 1200 zlotys/300$.
The launch of advertising campaigns was conducted on Facebook, Instagram, and YouTube.
What was accomplished
1. Detailed analysis of the market, competitors, target audience
2. Developed a promotion strategy for the school across all possible channels
3. Search and selection of the necessary team of specialists/marketing team
4. Developed a website and landing page with courses and webinars
5. Developed a proprietary platform for the school's courses
6. Created and packaged pages on social networks (Facebook, Instagram, YouTube)
7. Content plan for all involved social networks
8. Management of social networks
9. Creation and setup of Google Analytics, GTM
10. Developed a brand book for the company
11. Created and set up advertising accounts on all necessary platforms
12. Developed a sales funnel from the first touch to the moment of actual sale
13. Developed a Google spreadsheet for reporting and tracking sales and applications
14. Developed a plan and structure for selling webinars
15. Set up a service for conducting webinars
16. Moderation of webinars
17. Developed chatbots for automating the process of bringing people to webinars
18. Set up email marketing to warm up the audience for webinars and for selling the course
19. Developed creatives for launch on all necessary platforms
20. Wrote technical specifications for videos for advertising campaigns for the school owner
21. Wrote sales texts for chatbots and advertising campaigns
22. Launched advertising campaigns
23. Launched retargeting campaigns for those who visited the website and did not register for webinars, and for those who attended webinars and did not purchase
Results of the first launch
We have 98 applications for the course totaling 93,990 zlotys/23,953$.
Actual sales amounted to 76,760 zlotys/19,562$.
Actual marketing and advertising expenses were approximately 5000$. Unfortunately, we could not calculate the exact amount of expenses, as there were many small expenses that were not initially documented, and later we could not accurately account for them, which was a small mistake at the very beginning.
Based on the above figures, the net income from the first launch is 14,562$.

450 USD How a developer from Switzerland received 63 investment applications in 2 months
Social Media AdvertisingTargeted advertising for a developer from Switzerland (Garon) — a case study on attracting real investors in the complex real estate niche.
In 2 months, we launched an advertising system to find investors in the international audience and received 63 investment applications, of which 7 turned into real investments and closed project financing. No "hype," no mass traffic — just precise work with the target audience and validated hypotheses.
… The case shows that even in high-stakes and skeptical niches, targeting can provide not just leads, but money and investors, if there is a strategy and clear logic for engagement.
