We are building a sports booking platform that connects sports clubs and individual trainers with people looking for sports activities.

For sports businesses, our platform works as a CRM and booking system where they can publish services, manage schedules, communicate with customers and receive bookings.

For users, it is one place to discover sports activities, compare options and book them easily.

The product is already being developed, and now we are looking for someone who can help us solve one of our most important challenges: bring sports clubs, trainers and other sports providers onto the platform and help them start actively using it.

At the moment, clubs can use the platform for free, so this role is not primarily about selling a subscription.

It is about understanding club owners, building trust, introducing them to a new way of working, helping them understand the product and finding creative ways to grow our network of sports partners.

What you will do

You will own a large part of our business development, partnerships and communication with sports providers.

Your responsibilities will include:

• Finding and contacting sports clubs, studios, academies, trainers and other sports providers.
• Speaking directly with owners, managers and decision-makers.
• Building genuine relationships with sports businesses instead of relying only on standard sales scripts.
• Presenting our platform and demonstrating how the CRM works.
• Helping new partners understand the system and complete onboarding.
• Helping clubs publish their services, schedules and other information correctly.
• Following up with partners after onboarding and helping them become active users of the platform.
• Understanding why some clubs decide to use the platform and why others do not.
• Collecting feedback, requests and problems reported by clients.
• Keeping clear notes about client conversations, requested improvements, product issues and ideas.
• Organizing this feedback so that it can be easily communicated to the founders and product team.
• Helping us distinguish between one client's individual request and a problem that may affect many clubs.
• Building relationships with municipalities, sports departments, sports federations, associations and other organizations connected to sport.
• Looking for opportunities to work with sports communities, events, universities, companies and local organizations.
• Developing creative ways to attract clubs that go beyond traditional cold outreach.
• Thinking about advertising, partnerships, referral programs, local campaigns and other growth experiments.
• Tracking contacts, meetings, follow-ups, onboarding and activation in a structured way.

Communication with clients is a critical part of this role

We are looking for someone who can create an easy and natural connection with different kinds of people.

You should be genuinely interested in understanding how a club operates, what problems it has and what would make its daily work easier.

We do not want someone whose main goal is simply to convince the client that our product is good.

We want someone who listens.

Sometimes a conversation with a club owner may reveal that something in our product is confusing, missing or unnecessarily complicated.

In these situations, we expect you to understand the client's real need, ask the right questions, document the feedback and communicate it clearly to the team.

You will act as an important connection between the people using our product and the people building it.

Digital skills

You do not need to be a programmer and we do not expect you to write code.

However, strong modern computer skills are very important for this position.

You should:

• Feel confident working with web applications and CRM systems.
• Be comfortable learning new software without needing detailed instructions for every step.
• Understand basic concepts of modern digital security, such as MFA and why account security matters.
• Be comfortable working with online communication and productivity tools.
• Be able to demonstrate our CRM to clients confidently.
• Be able to explain digital concepts to clients who may not be technically experienced.
• Keep information about leads, conversations and client feedback organized.
• Write clear notes after meetings and calls.
• Report bugs, problems and improvement requests in a way that is understandable to the product and development team.
• Be curious about technology and interested in understanding how digital products work.

You do not need technical expertise, but you should feel comfortable in a technology-driven environment.

We are looking for someone who

• Is open-minded and genuinely curious about people.
• Is a good listener.
• Can quickly build a comfortable connection with business owners and managers.
• Tries to understand the client's real problem instead of immediately trying to sell something.
• Can translate client feedback into clear information for the product team.
• Is comfortable starting conversations with people they do not know.
• Can speak confidently with business owners and decision-makers.
• Has experience in business development, partnerships, sales, customer success, growth or a similar role.
• Is proactive and does not wait for a prepared list of tasks.
• Likes experimenting and finding unconventional ways to reach customers.
• Can understand why a customer says "no" and use that information to improve our approach.
• Is comfortable working in an early-stage startup where many processes are still being created.
• Can work independently and take ownership of results.
• Is organized enough to manage a pipeline of contacts, meetings and follow-ups.
• Understands that getting a club registered is not enough. The goal is to help the club actually start using the platform.

Experience in sports, fitness, marketplaces, SaaS, CRM products, local business sales, customer success or working with public organizations would be a strong advantage.

Location

We are based in Gdańsk and would prefer someone who is also based in Gdańsk or nearby.

Being local is an advantage because this role can involve meeting club owners, visiting sports facilities, attending local events and building relationships with organizations and public institutions.

However, Gdańsk is not a strict requirement.

We are open to strong candidates from other locations who are comfortable traveling to Gdańsk and meeting partners in person when needed.

This role is probably not for you if

You prefer receiving a ready-made list of leads and following a fixed sales script.

We need someone who naturally asks questions such as:

"Why isn't this club interested even though the product is free?"

"What problem does this club actually want us to solve?"

"What part of our CRM is difficult for them to understand?"

"Are several clubs asking us for the same feature?"

"Where can we find another 100 clubs like this?"

"What would make this club recommend us to other clubs?"

"Could we work with the city, federation or sports association?"

"Can we create a partnership instead of contacting every club individually?"

"Can we launch a campaign around a specific sport or local community?"

"How can we make onboarding easier?"

What success looks like

Success is not measured only by the number of emails sent or calls made.

We want to see:

• Meaningful conversations with sports businesses.
• Clubs and trainers joining the platform.
• Partners completing onboarding.
• Partners actively using the CRM.
• Real sports services and schedules being published.
• Users being able to discover and book these services.
• Useful client feedback reaching the product team.
• Product improvements based on real market needs.
• Partnerships that give us access to groups of sports providers.
• Acquisition methods that we can repeat and scale.

Why this role is interesting

This is an opportunity to join an early-stage product where your work can directly influence both the growth strategy and the product itself.

You will not simply be selling a finished product.

You will help us understand the market, build relationships with sports businesses, discover what clients really need and help shape the product around those needs.

You will work closely with the founders and product team, while also spending significant time talking directly with the people who use the platform.

If you enjoy communication, technology, sales, partnerships, experimentation and building something from zero, we would like to talk.

— Experience with a modern frontend stack (React/Next.js or similar)
— English at B2+: documentation, tools and part of our communication are in English
— Independence: the ability to take a task, see it through, and propose a better solution

— Basic understanding of web application security
— Experience working with analytics and SEO requirements at the markup level
