Strong marketing messaging for life science brands
Biotheia helps life science companies translate their deep domain expertise into clear and effective messaging that the market notices and responds to.

How's your messaging performing?
Your company has years of deep scientific expertise, but your marketing messaging may not reflect it.
As a result:
- It’s hard to generate (quality) marketing leads
- Lead generation over-relies on sales
- Your marketing simply doesn’t represent the business properly.
The truth is that if your core messaging is undefined and unclear, everything built on top of it will be … not good enough.
Why is it hard to fix messaging from inside
The fact is that messaging problems are hard to solve internally. That’s because:
- Leaders don’t have time or space to step back strategically and think
- They’re too close to the business and can’t see the gaps easily
- There’s constant internal change to manage + competing priorities
Leaders know the messaging needs work, but it keeps getting deprioritized because there’s always a more pressing priority.
Strategic messaging for life science companies
Biotheia is a marketing consultancy that specialises in messaging audits, development and implementation for life science companies.
We work with senior leaders to:
Critically assess what’s broken
Develop clear messaging that fills the gaps
Implement that messaging across high-visibility customer touchpoints
This is not surface-level copywriting.
You’ll get a strategic messaging framework with rapid implementation that market actually notices and responds to.

Services at a glance
We’re here to help life science businesses overcome marketing challenges caused by unclear messaging, at a strategic and execution level.
You can use our services individually, or combine them into a broader package if you need end-to-end support.
Messaging implemented where customers see it
Once you have new messaging, you’ll want to roll it out rapidly so it starts delivering results.
We will write copy to implement messaging across high-visibility customer touchpoints, such as:
- Homepage
- LinkedIn profile
- Conference banners
Additional touchpoints can be supported, depending on your needs.

Testimonials

Michael Ries, Director of Marketing & Sales
Cube Biotech
"Teja supported us with a product launch by creating a messaging strategy and comms deliverables. The launch was a great success for us. The project itself was running smoothly, the feedback loops were great and the internal team was also happy. The output documents were very professional."

Tim Craggs, CEO
Exciting Instruments
"Teja’s deep sector-specific marketing expertise, gained over many years working with scientific instrumentation, made her ideally positioned to support Exciting Instruments as we launched our marketing initiatives. She provided both strategic and tactical guidance through a well-researched, thoughtful, and targeted marketing plan. Working with her has been an absolute pleasure; she helped us scale our marketing efforts with professionalism and diligence, taking us swiftly from 0 to 1 and setting us up well for the future".

Nasr Esfahani, Founder
Guaranta
"I hired Teja to create a marketing plan for my microfluidics consultancy business. She first built an actionable marketing strategy that was perfect for the size and scope of my company. We also implemented numerous marketing-led updates to the content and structure of my website. Teja was fantastic to work with, her communication was excellent, and she was always punctual. I’m thrilled with the outcome. 🙂 I now have clear business messaging and a concrete marketing plan. I’d be delighted to work with her again".

Blaž Cugmas, CEO
Vetamplify
"Teja helped us get started with marketing when we launched our veterinary CRO business. Although our business field is very niche with almost no good examples, her consultation was full of actionable value, and we successfully launched a website and initial marketing activities. Teja's guidance was easy to follow. As a result, the first stage of business development was well realized".

Samuele Lisi, Consultant
Sustainable Marketing Consultant, Life Sciences
"Clarity, confidence, expert insights. This is what you get with a coaching session with Teja. I am also a marketer, but Teja brought me an extremely valuable external perspective. Before meeting her, my offer had gaps, and I struggled with pricing. But she provided insights that would have taken me forever to see. Thanks to that, I tweaked my messaging and secured leads through a multichannel marketing campaign. When you're a founder, a consultant, or the only marketer on your team, getting expert support can unblock a sticky situation and empower you to face them now and in the future".

Victor Lee, Founder
MedProductions
"I highly recommend Teja for her strategic marketing expertise. She helped us bring clarity and direction to MedProductions’ marketing when we had too many ideas and no clear focus.
Her guidance helped us prioritize what actually works. Her recommendations led to more targeted engagement from our ideal clients and has already started bringing in inbound leads.
Her insights have been thoughtful, practical, and directly impactful to our growth. We continue to consult with her whenever we need expert marketing advice."
