Spellbook Tech Stack

AI contract drafting and review platform for legal teams

Software Development Toronto, ON 201–500 employees Founded 2018 Privately Held

Spellbook is a Microsoft Word-integrated AI platform for contract work, adopted by 4,000+ in-house legal teams and law firms. The stack—OpenAI, Anthropic, React, Node.js, MongoDB, AWS—reflects a consumer-grade product philosophy (frontend-first, serverless infrastructure). Active hiring is skewed heavily toward sales (11 roles) and marketing (3) relative to engineering (5), signaling a shift from product-market fit to revenue acceleration. Security investment (penetration tests, threat modeling, bug bounties) is front-and-center, critical for a product handling sensitive legal documents.
