Spellbook embeds AI-powered contract analysis directly into Word, serving 4,000 in-house legal teams and law firms. The stack reveals a dual-focus organization: frontend (React, TypeScript, Node.js) paired with LLM APIs (OpenAI, Anthropic) for contract intelligence, plus a full sales and marketing apparatus (HubSpot, Salesforce, LinkedIn Recruiter). Hiring velocity is accelerating with sales roles leading by 10x over engineering, signaling a shift from product-market fit validation into revenue scaling—a pattern reinforced by active projects around lead generation, ad creation, and converting early traction into category leadership.
