Toolkit is building the world’s first ERP compiler:
⚡ Toolkit invented a way to create customized ERPs directly from spreadsheets at zero-marginal cost. It uses an ML + compiler architecture and takes minutes rather than years to implement.
💡 Because manufacturing ERPs are stuck in the 1980s: slow, low-quality, and built by expensive consultants.
💰 $124B/year dinosaur industry. Toolkit is architected to become the first winner-take-all ERP.
🛠️ Deeply technical founders, backed by the fund that backed Brex, Snowflake & Anduril ($3.4M Seed raised Q4 2024).
🚀 Founders forge founders. Join Toolkit to solve real, hard problems, then start your own company after.
