Matt Shumer

Matt Shumer is one of the original prompt engineering pioneers. As CEO of OthersideAI and creator of HyperWrite, he built one of the first AI writing assistants, reaching nearly two million users. But it's his work on prompt engineering techniques that made him truly influential. He created GPT-Prompt-Engineer, an open source tool for automatically generating and testing optimal prompts, and pioneered the prompt expansion technique that was later adopted by DALL-E 3 and Ideogram. His deep understanding of how to get the best results from language models has made him a go-to resource for developers building on top of AI. His viral blog post on X about AI's looming impact was viewed by more than 50 million people, making it one of the most-read AI takes in history. He also invests through Shumer Capital, backing AI infrastructure and agent-native products at pre-seed and seed stages.
