It became the #1 blockchain game by all-time NFT volume, introducing millions to crypto through gameplay. - **[Ronin]**: An EVM-compatible blockchain specifically crafted for game developers building player-owned economies. It is the #1 gaming-centric blockchain by all-time NFT volume. It provides the infrastructure for fast, low-cost transactions. - **[Mavis Ecosystem / Mavis Products]**: A suite of tools and infrastructure products designed to give game developers everything they need to build and scale blockchain-infused games, including wallets, marketplaces, and SDKs. ## Market Standing - **Valuation/Market Cap**: Not publicly disclosed.

The company is deeply integrated with the broader Web3 and gaming ecosystem. - **Growth Signals**: Despite a headcount reduction (-26.9% YoY to ~108 employees), the company is actively hiring (6 open positions as of mid-2025, with job postings up 500% year-over-year).

The company has weathered major market downturns (the "crypto winter") and emerged battle-hardened, with a focus on long-term building. ## Competitive Advantages - **Proven Track Record**: Sky Mavis is the team behind Axie Infinity, the single most successful blockchain game to date, which proved the viability of player-owned economies at scale. - **Full-Stack Ownership**: They control both the top game (Axie Infinity) and the underlying infrastructure (Ronin), creating a unique, integrated flywheel.

They are actively courting third-party game developers to build on Ronin, aiming to become the default blockchain for Web3 gaming. - **Infrastructure as a Product**: They are productizing the tools and infrastructure they built for Axie Infinity (the "Mavis Ecosystem") to lower the barrier to entry for other game studios. - **Delivering Real Utility**: Moving beyond pure speculation, Sky Mavis is focused on building practical, fun applications that demonstrate the value of blockchain ownership to a mainstream audience. ## Why Work Here - **Impact and Ownership**: The company culture emphasizes "Ownership" — employees are given real stake in the products they build and are expected to take ownership of their work. You will work on "things the world has never seen before" and conduct experiments blending gaming, economics, and political science. - **Remote-First, Global Team**: While headquartered in Singapore, the team is distributed across 11+ countries (with a large hub in Vietnam). They offer "work arrangements" to support flexibility. - **Benefits**: The company offers a comprehensive benefits package including: competitive salary, top-tier healthcare (medical, dental, vision), mental health counseling/workshops, guild sponsorships for team bonding, personal vacation sponsorship, learning & development sponsorship, and a Macbook for every new joiner. - **Culture**: Described as "fast-paced, active, and immersive," with a focus on "fast iteration, calculated experimentation." The environment is for "explorers" and "paradigm builders" who are comfortable with ambiguity and a high degree of autonomy. The employer rating on LinkedIn is 3.6/5.0, with compensation rated highest (3.8) and culture (2.7) and career (2.9) as areas for improvement. - **The Mission**: The company's stated mission is "Economic freedom, for everyone," which provides a strong sense of purpose beyond just building a product. ## Sources 1.
