In their own words

About the company & team

Squads is a financial technology company building products and APIs for the stablecoin economy. We build on open infrastructure, global money and internet capital markets to deliver better financial services to every business, individual and developer.

  • Squads Multisig: The premier multisig platform for Solana.

  • Altitude: A global business account to save, earn and move money.

  • Fuse: A personal finance app for stablecoins and tokenized assets.

These three products are powered by our stablecoin infrastructure and developer platform: Grid.

Our investors include Haun Ventures, Multicoin Capital, Electric Capital, Coinbase Ventures, Toly, Mert, and others.

Squads Multisig is our self-custodial platform for securing and managing assets on Solana. It's built for Solana treasuries, program upgrades, validator operations and token management.

Trusted by 450+ teams to secure over $10 billion in value, Squads Multisig is used by almost every team in the Solana ecosystem, including leading protocols such as Jito, Jupiter, Drift, Kamino, and Helius.

  • Kindness Matters. We show kindness and respect to all users, customers, and team members in every interaction (internal and external). Being kind compounds and strengthens our relationships.

  • Craftsmanship Excellence. We deeply care about the quality of everything we create. Every contribution, regardless of size, must meet our high standards for excellence.

  • Radical Transparency. We communicate openly and honestly with each other. Respectful candor is valued over comfortable silence, as we can't afford to miss insights due to fear of speaking up.

  • Bias for Action. We believe action produces information. At no more than 20% completion of a project we must have a working prototype to test and iterate on.

  • Speed with Purpose. We move with urgency and focus. Slow and expensive usually go together. Good, fast, and cheap outcomes are perfectly achievable through disciplined execution.

  • Professional Integrity. We never speak negatively about competitors, partners, vendors, or others. Such behavior reflects insecurity and provides no value.

  • Creative Problem-Solving. We value innovative thinking that challenges conventions. The best solution aligns with the task at hand, not necessarily with how things have always been done.

  • Team Over Ego. We share both successes and failures collectively. No individual's ego should surpass our commitment to the product and its impact.

  • Results Over Hierarchy. We do not care about titles in this company. No politics, no hierarchy. All we care about is winning together.
