Securing investors through targeted outreach

Securing 3 new investors with a 40% open rate and a 19% reply rate
Sierra Medical's mission is to change the landscape of medical diagnostics — creating a generalised model using spectroscopy that streamlines laboratories and delivers fast, affordable and accurate screening tests.

“I trusted my gut engaging with the Darwin team, and it paid off. Very happy with the work, they delivered where others couldn’t.”
Challenge
Sierra Medical came to Darwin needing help expanding into the US: investor outreach, communications with existing stakeholders, and keeping up credibility on social media, where their previous provider simply wasn't cutting it.
They had no outreach infrastructure, no marketing resource, and were overwhelmed by the complexity of breaking into a new market without the internal know-how to do it.


Solution
We built and launched an automated investor outreach campaign in lemlist, targeting 70 high-value healthtech investor organisations across the US. Rather than cold, generic emails, we tied every sequence to key industry events happening in the US, giving investors a timely reason to reply and to meet.
Alongside this, we restructured their stakeholder communications and took over social media management, designing a consistent, recognisable content style: data-led posts on the scale of the problem, thought leadership from the team and announcements such as new advisory panel members. Social engagement rose by 64%, giving investors a credible, active company to find when they looked Sierra Medical up.
