A New York company whose website and mobile app enables consumers to purchase discount prescription drugs online and pick them up from a participating pharmacy is hiring some serious ecommerce and social media talent.

Blink Health LLc launched as a free consumer website and app in February 2016 to let users search for the lowest available prices for generic prescription drugs and now claims to have 35,000 participating pharmacies and more than 500,000 consumers purchasing prescription drugs through its app. To support its ongoing growth, it has hired a trio of executives with experience at Amazon.com, Facebook Inc. and Microsoft Corp.

Blink Health has named Bharath Chinamanthur as executive vice president, engineering and operations. Chinamanthur joins Blink from Charles Schwab, where he worked as senior vice president for the Advisor Services Technology organization. He previously spent 11 years in an executive role in Amazon’s consumer and B2B divisions, where he helped launch Amazon Business. Healso was responsible for technical and operational merger and acquisition integration at Amazon Retail.

The company also hired Christopher Plambeck as senior vice president, data sciences and monetization, and Madan Nagaldinne as chief people officer. Plambeck, who has been self-employed for about the past year, earlier worked at Amazon in the hardlines business and oversaw book buying at Amazon.ca. He also spent over seven years at Facebook, initially overseeing monetization analytics and pricing, then led the marketing science group in the Asia-Pacific region.

Nagaldinne comes to Blink Health from Compass, a provider of online technology for buying and selling real estate, where he worked as chief people officer. Prior to Compass, Nagaldinne spent over 20 years developing workforces at companies including Facebook and Amazon. At Amazon, he is credited with helping increase the ecommerce giant’s footprint across Asia from 200 employees to more than 5,000.

Blink negotiates directly with pharmacies and pharmacy chains for discounted prices. Users of BlinkHealth.com or the app can shop for a drug and its price, pay online and then download a receipt they bring to a Blink Health participating pharmacy to pick up their order. Blink does not ship orders directly or hold any inventory.

The company, which didn’t break out online sales, claims to provide the lowest prices by using proprietary technology to group patients together so that they get bulk discounts.
