🔥 Spike Studio's Team & Culture

At Spike Studio, the culture is built around one core belief: enthusiasm creates progress. No matter how advanced the technology is, true transformation only happens when people bring passion and energy to their work.

As their CEO often says, “People with passion ignite teams, and that energy inspires others to move forward.” That’s the spirit behind their cultural statement: “Enthusiasm Enriches.” The belief is that enthusiasm enriches not only work, but also relationships and lives as a whole.

This culture is supported by three key values that define how people at Spike Studio work and grow together:

1. 🌱 Be Curious

Stay curious about how AI and technology are changing the world.

Spike Studio values those who keep learning with excitement — not just about technology itself, but about the new possibilities it creates for business and society.

2. 🐉 Dragon Hunting

Don’t be afraid to take on tough challenges.

Just like in a game, fighting only “easy enemies” won’t help you grow.

Spike Studio encourages their members to take on the “dragons” — the big, complex problems — because that’s how individuals and teams truly evolve.

3. 🌈 Good Vibes

Spike Studio believes great work comes from a positive atmosphere.

Respect, empathy, and open collaboration are at the heart of the company's teamwork. They strive to build a team where people genuinely enjoy working together and feel proud of what they create.
