About Biotheia: a life sciences marketing consultancy
Helping life science brands get noticed with clear and effective messaging.
What is Biotheia
Biotheia is a life science marketing consultancy run by Teja Sirec.
We’re here to help overcome marketing challenges caused by unclear messaging, whether at a strategic or execution level.
The services include messaging audits, messaging development and messaging implementation, as well as wider support with marketing strategy.
Mission and vision
I’m on a mission to fix the most overlooked growth blocker in life science marketing: unclear, empty messaging. Messaging is a growth driver, one that attracts the right customers.
I believe that commercial leaders shouldn’t rely on guesswork, unstructured opinions, or personal taste. Strategic messaging should be treated like any other critical system: audited, designed, and implemented with current best practices.
This is why I help life science companies visualise gaps with messaging audits, develop clear messaging narratives, and implement them across high-visibility touchpoints — so their expertise translates into visibility and better commercial outcomes.
About Teja Sirec
PhD in Life Sciences | Chartered marketer | SOSTAC® Certified PlannerI’m Teja Sirec, founder of Biotheia and a strategic marketing consultant specialising in messaging for life science and biotech companies.
I work with commercial leaders who feel their legacy marketing messaging is no longer aligned with the current business reality, which is stalling growth and creating friction.
My approach is pragmatic and execution-focused with particular attention to high-visibility customer touchpoints where new messaging makes the most impact.
My professional background spans both sides of the equation: a PhD in Life Sciences, and Chartered Marketer status, plus years of strategic and hands-on experience driving marketing programmes for life science companies.
My life sciences background
I have spent 15 years in the life sciences as a lab scientist (initially) and a marketer (now).
In the commercial environment, I worked in content, strategy and leadership-oriented roles in life science businesses, marketing the products and services to:
Academia
Biotech companies
Pharma and Biopharma
Contract organisations (CDMO, CRO, CMO)
I’m experienced in building life science marketing strategies, creating messaging frameworks and turning them into marketing outputs that drive growth.
Most of my customers are analytical instrumentation companies, reagent and consumables suppliers, and service-based businesses (CxOs, or other custom services).
Who I help
I work with commercial leaders in life science companies who know their legacy messaging is holding them back — but want a structured, pragmatic way to fix it.
Companies that require strategic messaging support typically navigate change:
Messaging misaligned with new business reality
Mergers and acquisitions
Business strategy pivots
New product launches
How I help
I help life science companies fix their marketing messaging.
I do this in 3 stages:
1) I audit your messaging to identify gaps between messaging and current business reality.
2) I develop strategic messaging frameworks to define how to communicate your desired positioning.
3) I implement messaging across high-visibility customer touchpoints by writing quality copy for key assets to roll out your new messaging rapidly.

"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."
