Sight Sciences, Inc., a venture-backed, commercial stage ophthalmic medical device company today announced it has closed an oversubscribed $10 million Series C round of growth financing and strengthened its leadership team with a seasoned ophthalmic industry veteran. Allegro Investment Fund, a privately held fund based in Menlo Park, CA, led the round with full participation from all existing Series A and Series B investors.

The company intends to use the funds to build out a market-leading commercial team in the United States, launch its breakthrough ophthalmic devices in Dry Eye and Microinvasive Surgery, scale up manufacturing, and complete clinical studies geared towards expanded product indications and strategic product positioning.

"Allegro has supported Sight Sciences from the beginning, and we have witnessed its technology platforms mature into breakthrough products that eye care providers confidently use to care for their patients," said Staffan Encrantz, Chairman at Allegro Investment Inc. "We look forward to supporting the Sight team as they work to elevate the standard of care globally in both glaucoma and dry eye, two diseases in need of high-yield innovation and more effective solutions."

"We are excited to partner with Allegro and welcome Staffan Encrantz to our board of directors as Chairman," said Paul Badawi, President and CEO of Sight Sciences. "Allegro is a skilled growth investor with a long-term view and strong history of supporting innovative companies like Sight Sciences as we achieve commercial scale and market leadership."

Simultaneously, the company announced the appointment of Shawn O'Neil as Senior Vice President of Sales and Marketing.

He is perfectly suited to lead our upcoming product launches and commercial scale-up and will make a substantial impact in creating value for all Sight Sciences stakeholders - patients, providers, payors, and shareholders," said Badawi.
