Enriching lives through experiences that move the heart — HEARTBEATS’ vision of “a society where every fan’s passion overflows”
Representative Director and CEO
Yuta Umesawa
HEARTBEATS is a startup in the sports and entertainment field that advances the industry through the passion of fans.
We place the highest value on what fans love. At the same time, we aim to maximize the power of what each HEARTBEATS team member loves and deliver new value to the world.
Even when the challenges are difficult, we are committed to making society better through the power of sports and entertainment.
Let us take on that challenge together, so that sports and entertainment become truly indispensable to society, not just “amusement.”



We would like to introduce the roles and rewards of each organization: the Content Partnership Business Division, the Creative Division, and the Engineering Division.
The Content Partnership Division is the core organization that creates services delivering new experiences and ways to enjoy content for fans, together with some of Japan’s leading content holders.
Teams are organized by partner content holders such as professional baseball teams and artist agencies, and each team drives its operations with the goal of delivering the best possible experience to its respective fan base.
While carrying out a variety of missions, including achieving each team’s mid-term outlook and business targets, “Planning & Sales” professionals who serve as account managers oversee communication with content holders and overall project planning. They lead projects forward in collaboration with members across different functions within the company.
They also play a role in jointly developing digital experience strategies in alignment with the content holders’ mid-term strategies.
It is a highly rewarding role, as each team’s product strategies and daily planning efforts are delivered directly to some of Japan’s most prominent content and their fans, and user feedback and performance metrics are reflected immediately in one’s work.
The Creative Division is the frontline team that produces the cards and designs fans hold in their hands. The subjects of these designs are extraordinary figures such as famous athletes and artists. By expressing their appeal through graphics and video, the team creates experiences that bring fans joy and excitement.
The greatest reward is seeing fans’ reactions come back immediately in response to the team’s creative work. It offers a daily sense of fulfillment from moving people’s hearts through creativity.
In addition, the division works across a wide range of IP genres including sports, music, and idols, providing an environment where new forms of expression can be constantly explored. By engaging with diverse projects across different genres, team members can build their careers while developing a broad set of skills.
The team brings together creators with different areas of expertise, who learn from one another while pursuing new forms of expression. The opportunity to take on creative work that connects directly with fans is a unique attraction of the Creative Division.
The Engineering Division works daily on developing new features and improving UI/UX so that we can continue delivering the best possible experience to fans and make the service even better.
With the belief that improvements to the developer experience ultimately benefit users as well, the team actively introduces consistent design principles, leverages generative AI, and holds study sessions.
One of the key rewards of software development at HEARTBEATS is the ability to actively discuss with the business side what kinds of excitement and thrills we can deliver to fans, and then translate those ideas into actual development.
It is also engaging to work on non-functional improvements unique to a growing product, such as enhancing processing efficiency to ensure stable performance even with a large number of users.
It is a challenging role for software development specialists who aim to excel in both technology and user experience.
