About Big Sister
Big Sister was born from a simple but powerful idea: no ambitious Registered Manager should have to give up on their dream of business ownership due to lack of funding, support, or guidance.
With decades of experience in global business development, we’ve helped 500+ healthcare businesses launch, grow, and secure £5 billion+ in government contracts. We saw firsthand the challenges faced by talented professionals who wanted to step into leadership but were held back by financial barriers, compliance complexities, and the uncertainty of going it alone.
That’s why we created Big Sister—a partnership, not just an investment. With our 50/50 co-ownership model, we provide funding, strategy, and hands-on support to ensure your business doesn’t just launch—it thrives.
