Today we announced the close of our $7 million seed round. The round was led by Polychain Capital, with participation from venture capital and strategic investors including dao5, Amplify Partners, Polygon, Blizzard, Axelar, and more. Founded last summer by a former fraud operations executive and computer security professors from UC San Diego and Carnegie Mellon University, Cubist is developing security-focused dev tools that help Web3 developers make safer dapps faster.<br> <br> Despite incredible advances in Web3 technology, dapp developers are still forced to cobble together custom infrastructure from incompatible languages, protocols, and security solutions. They spend long hours trying to make sense of low-level details of where and how their dapps will execute, creating an industry-wide drag on developer productivity. Worse, this status quo gives developers thousands of opportunities to make devastating mistakes.<br> <br> Cubist makes Web3 development efficient, seamless, and *safe*. Through our modular set of security-focused dev tools, Cubist brings software engineering best practices to the entire lifecycle of a dapp—from Continuous Integration (CI) testing to push-button deployment backed by secure credential management. This secure-by-design tooling empowers developers to design the best applications without needing to navigate complex interfaces and infrastructure. <br> <br> Cubist’s first offering is our newly released, [**open-source software development kit (SDK)**][SDK], the first SDK designed for multi- and cross-chain development and testing. Cubist’s SDK allows users to write cross-chain dapps as if they run on a single chain, and change chains or bridge providers with a single line of configuration. We are also building enterprise security offerings.<br> <br> “The future of Web3 will be powered by dapp developers building amazing applications. However, this future will not be possible if developers must continue to build custom tooling and infrastructure, stitch together incompatible point solutions, and lose sleep over the security of their tech stacks. This stifles innovation and leads to serious security vulnerabilities,” said **Riad Wahby, Co-Founder and Chief Executive Officer of Cubist**. “We’re building Cubist to break this bottleneck and let developers focus on delivering the best, most secure applications possible. Cubist’s obsessive focus on helping developers efficiently and securely build dapps will set the standards for both safety and productivity, and we can’t wait to help build the future of Web3.”<br> <br> “Even some of the most exciting innovations in Web3 have suffered from technical mistakes that are easy to make, expensive to find, and hard to fix. The problem is that developers simply don’t have the tools they need to prevent these critical errors,” said **Ann Stefan, Co-Founder and Chief Operating Officer of Cubist**. “Cubist takes a security-first approach that gives developers peace of mind at every stage of development. With the support of our investors and community, we look forward to making Web3 a safe, fruitful place for builders.”<br> <br> “Cubist is on an exciting growth trajectory, led by a team that is uniquely positioned to address today’s Web3 development and security challenges. By positioning themselves at the union between security, efficiency, and developer familiarity, Cubist is defining the next iteration of developer platforms to bring a better experience for all in Web3,” said **Luke Pearson, Senior Research Cryptographer at Polychain Capital**. “With Cubist, Web3 development will be faster, safer, and simpler. We are thrilled to support this incredible team.”<br> <br> “We met Cubist early in their journey and were immediately compelled by what they were building. Our conviction has grown even stronger with their first-of-its-kind developer toolkit,” said **Tekin Salimi, Founder of dao5**. “Developers looking for first-class security and a unified multi-chain development environment should look no further than Cubist. We can’t wait to see what’s next for the Cubist team.”<br> <br> “Web3 has the potential to be transformative—but many Web2 developers remain hesitant to dive in because they just don’t have the time to study every esoteric component of the Web3 tech stack. Cubist, backed by a world-class technical team, is raising the level of abstraction to eliminate this barrier,” said **David Beyer, Partner at Amplify Partners**. “I’m really excited for Cubist to unlock Web3 for the next wave of developers.”<br> <br> Our team brings many decades of combined experience in retrofitting security for real-world systems like Web browsers and runtimes, and collectively we have published over 80 research papers on computer systems, programming languages, security, and cryptography.
