WakeCap
WakeCap is a construction-technology company that puts a small IoT sensor into standard safety helmets to give project owners live, site-wide visibility into workforce, safety, productivity and progress.

Its technology has been deployed across roughly $80 billion of active projects - including Aramco, NEOM, Qiddiya and King Salman Park - and has tracked more than 150 million labor hours. WakeCap raised a $28M Series A in 2025 and operates from Riyadh, Dubai and San Francisco.

Bloomlife is a San Francisco maternal health company that pairs FDA-cleared wearable sensors with a connected-care platform so high-risk pregnancies can be monitored from home. Born from a co-founder's own NICU experience, the company shifts prenatal care out of the clinic and into the living room - tracking fetal heart rate, blood pressure and glucose, then feeding the data to clinicians through risk-stratification tools meant to catch complications earlier.
