WhiteHat Jr founder Karan Bajaj’s cancer care startup Complement 1 has raised $16 million in its seed funding round led by Owl Ventures and Blume Ventures, the company announced on Wednesday.
According to the company, it is emerging from stealth to launch the first tech-enabled, clinically validated lifestyle modification platform for cancer patients and high-risk individuals—delivering personalised daily guidance and education through one-on-one dedicated CoActive Coaches.
With the new capital, Complement 1 plans to scale up its coaching infrastructure and operations across the US, advance its AI-driven personalisation engine, and partner with cancer centres, health plans, and employers to bring the programme to their cancer patients, high-risk individuals, and survivors. The company will also invest in product development to enhance the digital user experience for both patients and coaches.
“Lifestyle change is one of the most powerful yet underused tools in cancer care,” said Bajaj, CEO and co-founder of Complement 1. “Every oncologist will tell you patients need more support incorporating clinically recommended physical activity, nutrition, and mind-body practices. We’ve cracked the code on daily engagement with personalised, compassionate coaching—helping patients make meaningful, lasting improvements during and beyond treatment.”
