Allium is building a canonical data layer for onchain finance, ingesting and standardizing data across 140+ blockchains to serve institutions, engineers, and AI agents. The company powers financial reporting, trading systems, and market intelligence for customers including Visa, Stripe, major banks, and Big 4 accounting firms.
As Head of Legal, you will own Allium's day-to-day legal operations and build the legal function as the company scales from Series B. You'll have substantial ownership from the start, working closely with founders and leaders across Finance, Sales, Product, and Engineering, with outside counsel available for specialist matters.
Key responsibilities include:
- Lead commercial contracting: Draft and negotiate enterprise customer agreements, data licenses, partnerships, and vendor contracts. Work with Sales and Finance to resolve issues and move deals through signature.
- Shape data and IP rights: Establish practical positions on data acquisition, permitted use, redistribution, derived data, AI use, and post-termination rights. Align supplier rights with customer commitments.
- Advise on products and partnerships: Work with Product and Engineering early on new offerings. Translate privacy, IP, and regulatory considerations into clear recommendations.
- Build legal operations: Develop templates, negotiation playbooks, approval guidelines, intake workflows, and a reliable contract repository. Use AI and automation thoughtfully with appropriate confidentiality protections.
- Coordinate broader legal needs: Partner with leadership and outside counsel on corporate governance, financings, employment matters, compliance, and other issues. Manage priorities and legal spend.
- Make obligations actionable: Help teams understand contract commitments and policies, and work with owners to implement them.
Allium values obsessiveness about quality, pro-athlete consistency, extreme ownership, high agency, leading by example, strong opinions about the future, and business acumen. The company is Series B-stage, recently named to The Information's Top 50 Startups and The Generalist's Future 50.
