Brett M. Renzenbrink


Brett works as “Outside CLO” (Chief Legal Officer) for a number of startups, emerging companies, and established organizations, from single member LLC startups to companies with nine-figure enterprise value and hundreds of employees. In this role, Brett adds accretive value to his clients’ growth, while forecasting blind spots and mitigating risk. In particular, Brett enjoys working with entrepreneurs, investors, and business owners to design corporate strategy and build out plans to finance growth; developing and implementing best practices for compliance with employees and independent contractors; negotiating with vendors and customers to create maximum net-benefit relationships; and instituting proactive and preventative litigation strategy and defending and enforcing corporate rights when suits are initiated.

Though industry agnostic, Brett has extensive experience working with venture capital funds and SPVs (including those with a cannabis-venture investing thesis), technology/SaaS-based companies (including blockchain/crypto/NFT-related), and transportation/logistics companies (in particular 3PLs) on architecting motor carrier/customer strategy and handling unique employee, supply chain, and compliance issues. He also has a track record of implementing creative techniques to assist clients, including architecting the “shared services platform” for nonprofits that dovetails with the “Outside CLO” platform, and goes over and above to establish extreme, results-oriented client service.
