Terry-Ann Burrell

CFO - Beam Therapeutics


Beam found themselves at a critical stage in their organization’s development: after having raised $200 million in private funding, the company was certainly well capitalized but wanted the option to tap into public investors. In order to have that option, they needed a highly respected Wall Street veteran deeply connected to The Street and able to articulate the Beam story in a way that would fully capture the company’s ambition and potential.


The challenge of recruiting a seasoned Wall Street banker to a private, entrepreneurial startup resides in psychological nuance. Investment banking is a radically different environment than a high science platform company. But there are transferrable skill sets around crafting narratives. Finding a banker with the requisite narrative gifts and managerial potential capable of being a team player in an early stage company was a challenge.


Occam successfully placed Terry-Ann Burrell, former Managing Director of Healthcare Investment Banking at J.P. Morgan, as Chief Financial Officer of Beam. Terry-Ann is thriving in her new role and successfully prepared the company for its February 2020 IPO.
