Life sciences, healthcare and health tech are some of the most complex buying environments in the world. Tallis helps vendors fix their GTM, navigate them, and grow the accounts that matter.
Tallis is a commercial advisory practice for vendors selling into life sciences, healthcare and health tech.
We work with commercial teams that have a real product but a hard market: buyers who are slow, political, evidence-driven and rarely in a rush. We've operated on the vendor side of that relationship for over a decade. We know where the deals stall, why they go quiet, and what it actually takes to close and keep them.
Tallis doesn't sell frameworks. It brings experience.
We work in two modes depending on what you need. Both start from the same place: an honest read of your commercial position.
For vendors whose GTM isn't converting at the rate it should
We run a structured diagnostic of your commercial motion: ICP clarity, pipeline quality, messaging, buyer navigation, and how you're managing the accounts already in front of you.
The output is a clear picture of where revenue is being left on the table and what to do about it. Most clients leave with a sharper ICP, a tighter value narrative, and a cleaner view of which accounts to prioritise and how.
For investors who need to know if the commercial story holds
We apply the same diagnostic to health tech and life sciences vendors on behalf of investors: pressure-testing market sizing, revenue assumptions, ICP fit and GTM execution before capital is deployed.
Independent. Evidence-based. Written for people who need to make a decision.
Account intelligence built for the rhythm of pharma and healthcare selling.
Managing a high-value account in pharma or the NHS isn't a CRM problem. It's a coordination problem: keeping your team aligned on the right stakeholders, the right signals, and the right next move across a buying cycle that can run for years.
SignalBook is an AI-augmented account workspace built for exactly that. Currently in early pilot with a small group of vendors.
We'll respond within one business day. The first conversation is always without obligation.
