Vellum is venture-backed and has received $24.5 million of funding to date. Vellum.ai builds tooling to improve generative AI prompting, born from founders' experience building production LLM applications. The product includes side-by-side model output comparison, company-specific data search to add context to prompts, testing, version control and fine-tuning/semantic search capabilities. The team—led by CEO and co-founder Akash Sharma with co-founders Noa Flaherty and Sidd Seethepalli—spun out of work at Dover and surfaced at Y Combinator’s Winter 2023 demo day. Vellum positions itself to help companies take LLM prototypes into production by preventing hallucinations and handling edge cases through refined prompts and prompt-chaining logic. The startup reports 40 paying customers and revenue growing roughly 25%–30% month-over-month, with pricing in the three- to four-figure-per-month range and a healthy seed-stage run rate. The founders argue the expanding enterprise demand for LLMs will drive continued need for prompt-engineering tooling.
