About Verant

Turning complexity into clarity isn't just a tagline. It's a description of what supply chain leadership actually looks like when it's done well — and a fair summary of why Verant exists.

Biotech companies at every stage need senior supply chain leadership, and the options for getting it are limited. You can hire full-time and wait months for the right person. You can bring in a large consulting firm and receive junior staff doing billable hours. Or you can go without, and manage the risk.

Verant offers a fourth option. Senior, experienced supply chain leadership — embedded in your organization, working as part of your team, available without a full-time headcount commitment. And when the work calls for hands-on operational support alongside strategic oversight, we bring in experienced supply chain professionals who work within the same framework and to the same standard.

The firm was built on a career that spans early-stage clinical organizations and large commercial operations — building supply chain functions from nothing, managing global networks at scale, running S&OP for a commercial portfolio across multiple continents, and serving as the supply chain lead through some of the most complex regulatory timelines in the industry. Across small molecule, large molecule, cell and gene therapy, and mRNA vaccines. Across companies at every stage from seed-funded startups to large commercial biotechs.

What that accumulation of experience produces is judgment. The ability to look at a supply chain situation — whatever stage, whatever complexity — and know quickly what matters, what doesn't, and what needs to be built next.

Rhiannon's career in biotech supply chain spans both ends of the complexity spectrum — from early-stage clinical companies building their first processes to large commercial organizations managing global supply networks across dozens of markets. She has worked across small and large molecule therapies, cell and gene therapy, and mRNA-based vaccines, at companies ranging from seed-funded startups to one of the largest commercial biotechs in the world.

Her path to supply chain began in the laboratory — cell culture development at Biogen, where she spent years supporting BLA filings, process characterization studies, and tech transfers to large-scale manufacturing. That scientific foundation shapes how she approaches every supply chain challenge. In biotech, supply chain decisions aren't purely operational. They're scientific decisions too, and leaders who understand that distinction make better ones.

Her subsequent career has covered the full scope of supply chain leadership: building clinical supply functions from scratch at Bioverativ and Turnstone Biologics; leading global supply planning at Moderna across its commercial portfolio, including serving as Supply Chain Product Lead for the COVID vaccine; and most recently building and leading the supply chain organization at Lyra Therapeutics as the company moved toward commercial readiness.

Rhiannon holds a Master of Science in Engineering Management from Tufts University, a Bachelor of Science in Chemical Engineering from Northeastern University, and the APICS CSCP certification. She is based in Topsfield, MA.

On the name

On the name

Verant comes from the Latin verare — to be true, to speak with accuracy. It's a name chosen for a practice built on giving clients honest assessments rather than comfortable ones.

The cairn in the mark carries a parallel idea. A cairn is a stack of stones placed on a trail by those who have passed before — not a monument, but a marker. Something left behind to help others find their way. That's a reasonable description of what good supply chain leadership does: it builds infrastructure, processes, and organizational capability that stays useful long after the engagement ends.
