Northeastern taught grad how to analyze cells. Now, it’s her business

By Hannah Morse October 26, 2026

Under the stars at Banff National Park in Canada, Hannah Sheehan Sauve looked for a sign.

She and her now-husband Jeff were contemplating whether starting a company together was the right step.

He had a career in sales and she was a scientist at a Cambridge, Massachusetts-based pharmaceutical research and development company. Her job centered around a technique known as flow cytometry – designing experiments for researchers, analyzing data and running an instrument that uses lasers and liquid to study a range of drug influences on the smallest parts of a cell.

Sheehan Sauve knew the market needed a one-stop shop for these services. 

Flow cytometers can be cost-prohibitive for burgeoning biotech and pharmaceutical startups that use this tool to validate the treatments they are developing. The device costs from $60,000 to $600,000 – and that doesn’t factor in the expense of having an in-house staff scientist to operate the tool and translate the results. 

Then, while at the park’s Lake Louise in 2024, the couple saw the northern lights, also known as the aurora borealis. For Sheehan Sauve, that was the sign they needed to start SauveBio.
