About Luthor

Luthor blends AI-native workflows with the judgment of former SEC attorneys, examiners, and seasoned compliance pros to deliver a full-stack compliance program so RIAs and broker-dealers can scale with confidence.

The problem we're solving

Every year, investment advisers, broker-dealers, and fintechs burn countless hours (and risk seven-figure fines) piecing together filings, surveillance, policy updates, and marketing reviews across disconnected tools and consultants. The result: launch delays, surprise deficiency letters, and teams stuck in compliance quicksand instead of serving clients.

How we solve this problem

Luthor replaces scattered tools and consultants with one AI-powered platform. Our LLM agents scan disclosures, AML and trading data, records, and marketing content for rule breaches, producing audit-ready docs in seconds. Former SEC attorneys validate every critical result, marrying speed with proven judgment. RIAs love us because we just do it all for them so they can go back to serving their clients.

Why we're hiring

Demand for a turnkey, AI-driven compliance solution is skyrocketing, and we’re onboarding RIAs faster than we can expand our team. Backed by real revenue and fresh capital, we’re looking for talented builders and regulators-turned-innovators to define the future of end-to-end financial compliance.

About Luthor

Luthor builds AI-powered marketing compliance agents for fintechs, banks, investment advisors, and broker-dealers. Our AI streamlines approvals, helping teams publish content faster—without compliance bottlenecks.

In regulated industries, every piece of marketing—tweets, LinkedIn posts, blogs—requires compliance approval, often delaying go-to-market by weeks. These slowdowns cripple growth. We’ve found that 60-75% of compliance checks can be quickly automated with AI. The challenge now is achieving a model with 95%+ accuracy, and that’s what we’re building.

Our vision is to be the marketing compliance layer for the entire internet.

Today, Luthor is already trusted by leading firms with $5.7B+ in AUM, backed by strong capital, and growing fast. Join us at the ground floor.

This is startup life in its truest form: fast-paced, challenging, and immensely rewarding. You’ll take ownership of your work, see the immediate impact on customers, and help define the engineering culture for years to come.
