Our Leadership Team
Success Through sophistication
As CEO and co-founder of Donblas, Princess leads a deeply experienced leadership team in building predictive case technology that models the structure beneath legal language — enabling law firms and businesses to anticipate outcomes through disciplined, data-driven analysis.
Her insight comes from living the challenge firsthand. With over a decade of legal experience, she has navigated the full spectrum of complex legal challenges. As in-house counsel at Eldridge, she managed complex transactions across tech, media, and real estate, where critical decisions required synthesizing evolving information and making confident calls despite unavoidable ambiguity. She saw the legal industry poised to benefit from the predictive intelligence already revolutionizing finance, healthcare, and technology.
This insight deepened when she launched The Chief Counsel, a boutique practice advising startups and growth companies on financing, compliance, and governance. Working with founders taught her that legal risk is not just a cost. It is a competitive differentiator when managed strategically. The challenge, however, was that most companies lacked the resources or tools to turn legal insights into business advantage.
Donblas solves this. By combining legal expertise with advanced AI, the platform delivers what Princess wished she had had her entire legal career: clear, actionable intelligence that turns legal complexity into confident decision-making.
