We’ve built a community of developers, engineers, CTOs, and VPEs that recommend, review, and share their technology stacks. They have significant buying power and a need for tooling and infrastructure services, from startups to large enterprises. The options they have are confusing and increasing in number by the day - they’re desperate to get help choosing the right solutions. StackShare lets technologists see all the best tools and services, who are using them, and why. | | Seed | Sep 20, 2021 | | | Flume | Flume is a modern fiber company bringing new home broadbands options.
