RTW does deeper diligence than nearly any other investor I know. RTW’s research and guidance in the early days of Rainbow and noninvasive hemoglobin was a valuable resource. They helped us understand the opportunity and have been a trusted partner since.

RTW really took the time to understand our business, and they understood that the reasons that other people had said no were actually the very reasons to say yes. They backed us early and made good on their promise to be a true partner long after Establishment Labs' IPO. They are the entrepreneur's investor and a real value add.

RTW’s passion for science and rational approach toward therapeutics development have been essential to the RCKT story. Rod and team have an uncanny ability to identify opportunities that no one else has, well ahead of the curve, and the rigorous discipline to water them gently. We value them highly as top shareholders, as founders and integral members of the Board, and most importantly as friends.

The RTW team did deep commercial diligence into the potential for a prophylactic HAE medicine well before other investors. Combined with their deep understanding of science, RTW was a terrific long-term shareholder, as we advanced DX-2930 through the clinic and sought to bring this important therapy to patients.
