Sigma Startups

Knapsack is a SaaS platform that helps design and engineering teams collaborate on design systems by allowing them to reuse modular design patterns and components. Founded by Chris Straw and a co-founder in 2020 after their design systems agency (Basalt) collapsed during COVID, the company grew from $900/month to $40,000/month in under 12 months by pivoting from enterprise-focused sales to a product-led growth model with a $25/month entry point. They raised $2.3M at a $7.5M post-money valuation in January 2021 and currently serve 80 customers with a net dollar retention of 190%.
