Steven M. Ayr

Partner


Administrative Assistant

Abby Kraus

Steve is a corporate attorney who represents businesses and their founders through all stages of their life-cycle, from early-stage formation and financing, to their day-to-day operations, and through exit. Industry agnostic, Steve is the first call on legal matters for founders in a range of industries, to whom he provides practical, efficient, and tailored advice taking into account each client’s unique business, challenges, and priorities.

As counsel to early-stage companies, Steve works with founders to form their entities, put the legal pieces in place to be operational, and take in the financing that will help them grow and execute on their vision.

As a company grows, much of Steve’s focus is on drafting and negotiating the agreements that form the backbone of an operating business, but Steve also has a particular focus on intellectual property and data privacy matters, helping clients manage and protect IP portfolios, draft and maintain online privacy policies and disclosures, and maintain compliance with data privacy regulations.

Finally, Steve frequently represents founders and companies in the sale of their business. As deal counsel, Steve functions as part of a team, including a client’s tax advisors, employment counsel, and regulatory specialists when needed, to ensure that the client realizes the most value out of what they’ve built.

Prior to Casner & Edwards, Steve started his own law practice right out of law school in 2009, before joining a small startup-focused law firm that was acquired by Casner & Edwards in 2017.
