Brad Menezes, CEO of Superblocks, believes billion-dollar startup ideas can be found by studying system prompts used by AI startups.System prompts are detailed instructions used by AI startups to train foundational models in specific domains and tasks.Superblocks shared 19 system prompts from popular AI coding products like Windsurf, Manus, Cursor, Lovable, and Bolt.Menezes highlighted that prompt enrichment around the system prompts is crucial, constituting 80% of the 'secret sauce'.The three components of system prompts to study are role prompting, contextual prompting, and tool use.Role prompting gives models purpose and personality, while contextual prompting provides relevant context for actions.Tool use enables models to perform agentic tasks beyond text generation, such as editing code and querying databases.Superblocks aims to allow non-programmers to write apps by handling security and access to enterprise data sources.Menezes restricts software engineers at Superblocks from building internal tools, encouraging the use of the product for various needs.Superblocks has gained customers like Instacart and Paypaya Global, focusing on providing vibe coding tools for enterprises.
