Performr.ai

Performr.ai is a London healthtech building wearable, on-body sensors that aim to provide continuous health and performance data without drawing blood. The company's stated goal is to deliver something close to a blood-test panel — vitamins, minerals, hormones — through a smartwatch-format device, in real time.

The technology centres on molecular-level biomonitoring through non-invasive sensors. Rather than building yet another fitness tracker optimised for one type of user, the team is positioning Performr as a wearable that adapts to the wearer's changing priorities across training cycles, life stages and health conditions, with the pitch being that it should remain useful long after most wearables end up in a drawer.

Performr was founded in late 2024 by Fizel Nejabat, previously the co-founder and COO of Series B fintech Algbra. The company is in early development, working towards a consumer launch of its first device.
