Build the technology stack every startup needs to move fast.
Early-stage startups need a lean stack that keeps a small team fast: collaboration, a simple CRM, payments and accounting, plus product analytics once there is a product to measure. The rule is to buy affordable tools with free tiers, avoid lock-in and add systems only when a real workflow breaks.
