How to Navigate Undefined Markets in Medtech

Interview with Materna Medical CEO Tracy MacNeal

Key Learnings From Tracy's Experience

  • Use clinical data to bridge B2B and B2C — but don’t mix models without a strategy. Consumer interest can accelerate clinical adoption, but only if both channels reinforce the same strategic goal. Clinical data gives you the credibility to communicate clearly to patients and providers alike — but without alignment, you risk burning capital without traction. Choose your primary channel early, and treat the other as a multiplier, not a distraction.


  • If you’re in an undefined market, expect to do the groundwork yourself. In emerging or overlooked conditions, there may be no consensus on definitions, inclusion criteria, or even the name of the problem itself. Materna’s team aligned KOLs to publish a white paper before running trials — a move that proved just as critical as the device itself. It’s slow, high-effort work — but it builds the foundation for clinical trials, FDA clearance, and long-term category creation.


  • Lead investor conversations with a focus on returns — and back it with founder fit. Investors want to know how much and how soon they’ll get paid back, but in early-stage medtech, they’re also judging whether the founder can weather what’s ahead. It’s not just about confidence — it’s about being able to project clarity, earn trust, and stay steady when plans inevitably change.

Despite being one of the world's most advanced healthcare systems, the United States faces a troubling reality in maternal care. While childbirth represents the leading cause of hospitalization, American maternal outcomes lag significantly behind other industrialized nations, with complications occurring at rates far exceeding international standards.

"Black women are three or four times more likely to die compared to white women with the same symptoms," says Tracy MacNeal, CEO of Materna Medical, noting that all women face a 20% lifetime risk of having pelvic floor surgery. "She's five times more likely to have pelvic organ prolapse if she's had a vaginal delivery."

For Tracy, these aren't just statistics — they represent a massive clinical need and market opportunity hiding in plain sight. After talking to hundreds of investors about Materna's work, she notes an unusual dynamic: "I rarely see startups with a market opportunity that size with no competition. No one has ever asked me how we're different from the other company that's doing this.

Materna is developing two devices addressing different aspects of pelvic health: Ellora, aimed at preventing childbirth injuries during delivery, and Milli, designed to treat vaginismus, a pelvic floor condition that makes intercourse painful or impossible. Together, they represent Materna's mission to "empower women to protect and restore their pelvic health" in a field where innovation has been virtually stagnant since the 1960s.

The company's early pilot study with Baylor College of Medicine showed a 60% reduction in pelvic floor injury rates — an impressive result that caught Tracy's attention and ultimately convinced her to take the CEO role.

"It would be much better if instead of treating prolapse and the associated incontinence later, women could have a baby vaginally and walk out with the same pelvic floor they walked in with," she explains.

How to Make B2C and B2B Work Together in Medtech (Instead of Against Each Other)

When Tracy joined Materna, she inherited a unique commercialization challenge: Their first product, Milli, was being sold direct-to-consumer as a wellness device, while their pipeline product, Ellora, required complex hospital sales with global codes and new technology add-on payments.

The fundamental issue was organizational: "They're just not the same call point. They're not the same sales team. And that's just impossible," Tracy explains.

Rather than abandoning either approach, Tracy developed a strategic B2B2C model that leverages the strengths of both channels while addressing their fundamental weaknesses. The key insight: clinical data serves as the bridge between consumer demand and physician adoption.

Her first move was taking Milli through two FDA clearances, transforming it from a wellness product to an FDA-cleared medical device. "I don't need FDA clearance to sell something, but without it, I can't say what the product is or what it's for," she notes. "Given how deeply underserved that population is — they don't know that what they have is common, they may not know that it's treatable — they certainly need someone to speak plainly to them. In order to speak plainly, you have to have FDA clearance and clinical evidence."

The strategy is already demonstrating results. Milli now has over 5,000 patients and 15,000 patient emails in their database, along with relationships with 5,000 healthcare providers. "We've built up that channel so that our second product, Ellora, can drop into it," Tracy explains. "When we commercialize Ellora, we'll sell into hospitals, but we'll also use those Milli channels."

This approach addresses two critical challenges of direct-to-consumer strategies in medtech. First, customer acquisition costs can be prohibitively expensive, especially for medical device companies without the deep pockets of pharmaceutical giants. Second, traditional medtech acquirers often lack consumer-facing capabilities, potentially limiting exit opportunities.

"When it's done right, you can really accelerate adoption among doctors when patients show up asking for it," Tracy observes. "There's an opportunity, and our acquirers  recognize it as such,  that you can use patient demand to accelerate your revenue growth when you launch."

The B2B2C model also provides crucial market validation. "Anything you could sell to a consumer, you should be able to sell to a doctor as well," she notes. "I think a lot of players end up going D2C, patient pay, because they couldn't get funding to do it right — to run proper clinical trials showing superiority and get FDA clearance to make those claims."

What You Should Do When the Medical Community Can't Agree on What You're Treating

Materna's clinical development strategy illustrates the challenges of working in undefined medical markets. When Tracy began developing clinical trials for Milli four years ago, she encountered a tricky problem: the medical community couldn't agree on basic definitions of the condition they were treating.

"We were so early to the game that there was not enough information — even in a systematic literature search — about this condition to get the inclusion criteria," Tracy recalls. "There wasn't even alignment among our key opinion leaders about what this was called, who has it, and how they would know."

The condition, vaginismus, affects up to 17% of American women at some point in their lives according to American College of Obstetricians and Gynecologists (ACOG) estimates, yet it's not comprehensively taught in medical school and is under-researched. Patients seeking help face a frustrating journey: "On average, our patients see six or seven clinicians who dismiss them and tell them it's all in their head, that they just need to relax and have a glass of wine. They've often been suffering on average for five or more years,” Tracy says. After using Milli, “patients can see significantly reduced pain and anxiety, and most are making progress on their goals in as little as 90 days.  There is no reason for women to struggle with this condition for so long, when Milli makes it so treatable."

Rather than abandon their clinical strategy due to the lack of medical consensus, Tracy orchestrated a solution that required both scientific rigor and diplomatic skill. "We got those key opinion leaders together and that team wrote the white paper. We're taking a stand. This is what this condition is. This is what it's called.  This is how we define it as a medical community."

The process required finding common ground among disparate medical opinions. "We had our chief medical officer interview three or four of the KOLs, and where everybody agreed, that was the white paper. Then there was an addendum with case studies written by each of those KOLs."

This collaborative approach extended beyond mere consensus-building. The team then conducted what is called a "Self Selection Study," the first of its kind in the field of vaginismus, proving that patients could accurately self-diagnose when given proper information — a finding that became part of their FDA labeling and enabled over-the-counter clearance.

"We proved that if you give patients the right information, they know what they have," Tracy explains. "It's not rocket science, and we don't need to be protective or paternalistic about it."

Materna's dual-product approach also helped their clinical strategy. Since Milli was already generating revenue, investors felt more confident funding Ellora's expensive clinical program. "Ellora needed a large clinical trial with 700 patients because it's in labor and delivery, which is a super high-risk area. That wasn't probably going to have an easy time getting funded, but our investors liked that we had a post-revenue product," says Tracy.

For founders working in similarly undefined clinical areas, Tracy emphasizes the importance of thoughtful self-awareness: "You have to figure out what your strong suits are and play to them and have your eyes wide open about what your soft spots are and not deny them…figure out how to get around them and build a strong company despite them."

Raising Money When You’re Not a ‘Fundraising CEO’

Tracy’s approach to fundraising reflects both her engineering mindset and hard-won lessons from the trenches of medtech. When she interviewed for the CEO role at Materna Medical, she was candid with the board: “If you're looking for someone who has a great Rolodex of venture capitalists in Silicon Valley, that's not me. I don't know anybody, actually.”

What she did bring — and confidently pitched — was a deep background in complex B2B business development and a knack for telling compelling stories. “If you're looking for someone who's comfortable walking into a room and telling a story to people I don't know, yeah, I can do that,” she told them.

Tracy likens fundraising to matrixed selling: a process of navigating uncertainty, aligning stakeholder incentives, and earning trust. “You're trying to find your people, you're telling a story, you're selling,” she explains. But that story has to hit a specific note: “The number one thing that investors are listening for is when they are going to get their money back and how much they’re going to get. Everything else is subordinate to that.”

This clarity has shaped how she runs investor meetings. Founders can easily get caught up in features, markets, or regulatory nuance. Tracy keeps the focus on financial return — and the CEO’s believability in delivering it. “When things go wrong, which they inevitably will, who are you going to be? Are you someone they need to fire, or someone they can lean on to get their return on investment?”

Importantly, she’s also had to evolve her own relationship with leadership and confidence. “A lot of us are brought up to make people comfortable and not take up too much space,” she reflects. “But there are times you have to be incredibly brave and bold — and be okay with making people uncomfortable.”

This balancing act — between humility and conviction — is especially critical for medtech leaders navigating long, complex development cycles. “I believe in my story,” she says. “I had contingencies, upsides, and downsides. Where the rubber really meets the road is the financial model. What do I know, what don’t I know, and how can I help people come with me and feel safe?”

Her advice to fellow CEOs: prioritize self-awareness and honest, trust-building communication. “I'm not into manipulating people or making them want something they don't want. We’re developing a specific type of field that's so strong that the right people are attracted to it.”

Looking Ahead: What’s Next for Materna

As Materna looks ahead to Ellora’s anticipated 2026 launch, Tracy remains focused on the broader transformation the company hopes to drive in women’s health. If successful, Ellora could become the first product in decades to receive a new reimbursement code and additional payment in labor and delivery — a milestone that may unlock further innovation in a historically overlooked space.

Materna’s approach — combining rigorous clinical evidence, patient-centered design, and thoughtful commercialization — offers a potential model for other medtech founders tackling underrecognized markets. “If you're working in a space that's  underdefined and you are genuinely a first mover, it's going to be expensive and it's going to take some time,” Tracy says. “Figuring out how to do it affordably, thoughtfully, without blowing too much capital is key.”

For her, the work goes beyond commercial success. The maternal health disparities that first drew her to Materna remain a driving force. “This is major quality-of-life stuff that people live with and don’t talk about.”

Her advice for early-stage medtech founders is clear-eyed: “If you succeed, you’ll probably be doing it for 10 years. It used to be five, but it’s gotten longer. So you better love it — because it’s a journey.”
