"Working with David Yamaguchi was an outstanding experience. He delivered a full suite of foundational legal documents for my tech startup—including NDAs, software development agreements, and master contractor agreements—with precision, clarity, and founder-first protection built into every line. David was responsive, efficient, and incredibly sharp when it came to aligning legal strategy with business goals. His ability to turn feedback into actionable revisions while keeping the documents clean and enforceable made the process smooth and stress-free. If you're a founder, entrepreneur, or growing business in need of high-quality legal work, I highly recommend David. He’s professional, detail-oriented, and clearly understands how to protect companies without overcomplicating things. Would absolutely work with him again."
