Our take
Numan is a digital health startup that was initially focused on treatments for men, offering a range of solutions for erectile dysfunction (ED) and hair loss, both themes related to male self-esteem that are often avoided and ignored.
The company has since expanded into areas like premature ejaculation and weight loss, alongside a comprehensive suite of diagnostic blood tests, live doctor consultations, and various personalised supplements. More recently, it has expanded its weight loss category into women's health, paving the way for a broader range of female treatment categories. In practice, Numan’s platform enables free online medical consultations, clinically proven treatments, diagnostics and personalised treatment plans.
And with solid funding, Numan is now working on further investments in technology and expansion of its operations. It's also made a number of key senior hires recently which will be sure to help enhance the company's product offerings and broaden its services to ultimately reach more customers.
