Marielle Delphine Briant | Product design & strategy
Proof of concepts that convert into long-term investments
I help early-stage, health tech startups go from $1-10M by launching B2B products that turn pilots into paying customers
Who I work with
Healthcare Founders
You’ve worked hard for the first few years, quickly shipping features to find product-market fit. As a Founder, you have the domain experience to understand the opportunity, but lack the expertise to translate customer requirements into potential design solutions. Your team is great at implementing features and prioritizing user needs, but less adept at solving for your customer’s pain points.
Product Leaders
You’re trying to work out what is the right set of things for your team to focus on that will have the greatest impact on the business. You need a thoughtful designer who understands the full business scope of what you are trying to achieve, can help to provide structure to the project, and executes well against priorities.
User experience has replaced price and product as the key brand differentiator. You’ve probably witnessed this yourself – nobody pays just for a "product” anymore.
In fact, my combined 10 years of experience working with startups in both the software and health tech space has taught me that customers will accept a product that is not A+ if you’re on your way to solving a problem that they can’t solve anywhere else.
That’s where I come in.
I help early-stage, health tech companies get out of obsessing over products and feature delivery and start focusing on problem-solving.
Experiencing any of these problems?

Lack of a clear Unique Selling Point (USP). You’re still learning how to articulate your value proposition so you’re not yet giving users a compelling reason to stick around

Loosing customers before you even launch. Your customers want personalized experiences and immediate value for less effort but your product is not intuitive or easy to use

Lack of clear goals or a destination. Your team has been working hard but needs some help connecting the dots to align the product roadmap to your company strategy.
I offer three paths to launching your B2B product:

Kind words from clients, mentors, and friends:

Keeping both your customers and users in mind at all times is critical for any business. Marielle’s business and enterprise acumen was something we really needed on our team. Her ability to constantly bring the focus back to the customer and help us to design features more holistically was a big value add.
Mel Faxon
COO/Co-Founder, Mirza

I can confidently say that Marielle is in the top 5% of people I’ve ever had the pleasure of working with. When we met I was launching Ollie's Tea and in the process of validating product-market fit. Marielle was instrumental in helping me save both time and money at a crucial time for my business. She brought a thorough design process to the project and her design council – which I am lucky to still benefit from today, has been invaluable.
Ronny Obiri
Founder/CEO, Ollie's Tea

Marielle is a highly strategic designer. I’ve seen firsthand the value she brings to her craft and clients. Her unique background spans industries and company sizes which brings focus and momentum to her efforts. Whether you’re an early-stage founder or established team, expect unprecedented results should you be lucky enough to hire her.
Andrew Graunke
VP of Enterprise Design, Toptal

Marielle is a true champion for User Research. I highly recommend her for any project that involves an in-depth understanding of people's feelings and motivations. In UX we throw around the word “empathy” a lot but Marielle is truly empathic. She's confident and poised, but also approachable and friendly – all of which make great attributes for talking to users. And did I mention she can make a pretty awesome spreadsheet?
