Company Building Starts with Discipline

Interview with Evident Vascular CEO Howard Rosen

Key Learnings From Howard's Experience

  • Go slow early so you can go fast later. In medtech, rushing product development often leads to misfires with regulators, customers, or commercial teams. Evident invested its first year in validating the problem, assessing the market, assembling the right KOLs, and staying laser-focused on what truly belonged in their first-gen system.


  • De-risking starts long before submission. At Evident, multiple pre-submission meetings helped shape a smarter, more confident regulatory path — even without clinical trials. For Howard, early engagement with FDA wasn’t optional; it was a deliberate way to de-risk development, align expectations, and avoid surprises down the road.


  • Your board isn’t just oversight — it’s strategy. The right partners bring more than capital; they bring patience, trust, and alignment when things inevitably get hard. A strong board sets the tone for how you operate — and how you're perceived. The same goes for strategics: don’t just seek attention, build relationships early and show up with a clear, credible message.

In medtech, there are rarely second chances when commercializing your technology.

Howard Rosen, co-founder and CEO of Evident Vascular, has spent three decades proving this principle — and building a career on it. With two successful exits to Philips and deep experience across startups and strategics, he’s developed a contrarian philosophy: forget “fail fast.” In healthcare, you launch right, or you don’t launch at all.

That mindset shaped his approach when Vensana Capital handed him an early concept with big potential. The target? Intravascular ultrasound (IVUS), a category where clinical demand had grown steadily — from 15% to 30% in peripheral arterial procedures — but the underlying technology hadn’t kept pace.

"Some companies focus on ease of use, and some companies focus on image quality, but no one company could do both," Howard explains.

Evident aims to overcome that trade-off, combining superior image quality with AI-powered interpretation and streamlined workflows. The company has moved at remarkable speed, going from concept to planned FDA submission in just four years — all by following a counterintuitive playbook: sometimes the fastest path forward requires the discipline to deliberately slow down.

Disrupting a legacy market takes more than innovation. It takes deliberate strategy: building slowly, launching methodically, and resisting the pressure to sprint before the track is laid.

Why Fast Isn’t Always Best in Medtech

Howard’s “go slow to go fast” philosophy runs counter to typical startup urgency, but it’s grounded in the realities of medtech. In a field where rushing can lead to regulatory missteps, product-market mismatches, or failed adoption, a thoughtful upfront strategy is often the quickest path to a successful launch.

At Evident, that mindset shaped three foundational decisions:

1. Validate the Market First, Then Build the Product

Evident began not by designing a device, but by deeply understanding the problem. “We really spent our time from the ground up assessing the market,” Howard says. “Just doing all the basic things you need to come up with a unique design that’s differentiated.”

That meant an entire year of voice-of-customer work — not just asking what physicians wanted but digging into why existing solutions fell short. Starting from a loose concept, the team validated every assumption before committing resources. The result: clear alignment around the one problem no company had solved — delivering both image quality and ease of use in IVUS.

2. More Than Advisors: KOLs as Cultural Architects

Howard also approached building an advisory board with unusual intentionality. Rather than stacking the deck with obvious names, he curated a cross-specialty group that reflected the realities of peripheral vascular care — interventional radiologists, interventional cardiologists, and vascular surgeons — from diverse practice settings.

But what really made the difference: how early and directly those KOLs engaged with the team. “Before we even moved in here — when there were just a couple of us — I had each physician come in and talk to the team,” Howard says. “About their cases, about IVUS, and why a better solution is so important.”

That early exposure created what Howard calls a “foundational aspect of our culture.” These advisors weren’t just opinion-givers — they were mission-shapers.

3. Discipline Over Features: Defending the First-Gen Product

The third pillar of Evident’s approach: ruthless focus. From the start, Howard and his co-founders Danielo Piazza and Patrick Phillips, enforced strict guardrails on the company’s first-generation product. “With software and other bells and whistles, it’s very easy to have scope creep,” he says. “I started saying no as a complete sentence.”

And it wasn’t just engineers pushing new ideas — even their scientific advisory board brought big visions. Rather than squash innovation, Howard redirected it: “Yes, we can do these things — but not in the first gen. Let’s build a real pipeline, and we’ll get there. But we must stay maniacally focused.”

That same discipline extends to commercial planning. Despite his background in sales and marketing, Howard is resisting the urge to scale quickly. “There’s nothing like being in the lab the first time. And with this kind of technology, we’re going to be very methodical about where we go before we scale.” Because, as Howard confirms, “how a product performs in a clinical study is very different than how it performs in a commercial environment.”

De-Risk Early: Submission Isn’t Where the Journey Begins

The same discipline that guided Evident’s product development carried through to its regulatory strategy. On paper, Evident’s pathway is well understood from contemporary FDA guidance: a predicate-based 510(k) clearance with no clinical trials required. But Howard knows from experience that “well understood” doesn’t mean risk-free.

“We’ve had numerous presubs, and we have more ahead of us before we submit,” he says. The goal isn’t just box-checking — it’s relationship-building. Howard learned from past companies that regular FDA engagement is essential, regardless of how familiar the regulatory path may seem. “Whether it’s a modular PMA or not, to me, you’re constantly talking to FDA along your journey. FDA wants you to talk to them.”

That mindset reflects Howard’s commercial background: relationships matter more than transactions. “You don’t want to submit something that’s not fully ready for them to receive,” he says. He likens it to cold calling — showing up with no context or trust.

 This goes against the usual thinking that a predicate-based 510(k) doesn’t require much interaction. Howard sees that as a missed chance to de-risk. For him, it’s simple: your first submission isn’t the time to take risks. “I don’t think there’s room for creativity there,” he adds. “It may sound conservative, but you want to de-risk as much as you can with the resources you have.”

The benefits are both strategic and practical. Early and frequent engagement with FDA has given Evident clarity on expectations, reducing the chances of costly delays or unexpected requirements. “It actually saves FDA time as well,” Howard notes.

More broadly, this regulatory strategy mirrors Howard’s company-building philosophy: build trust early, then leverage it for more ambitious goals. For a startup preparing its first submission while developing a pipeline of future applications, establishing that foundation with FDA could be a critical long-term advantage.

Multiple pre-submission meetings also serve as a form of market validation, ensuring Evident’s regulatory interpretation aligns with FDA expectations. In a space where larger incumbents often have longstanding agency relationships, that kind of proactive engagement helps level the playing field — and can become a strategic asset.

Why Board Composition Beats Valuation Every Time

Just as strategic engagement helped Evident build a relationship with the FDA, Howard brought the same relationship-first mindset to the investor landscape. When he set out to raise the company’s Series B round, he faced “a slog” — a nine-month process that tested his resilience and challenged conventional startup wisdom about how to pick the right investors.

“It was hard, and I learned a lot,” he says. “We're in the business of making a lot of friends. You learn not to take the ‘no callbacks’ personally — everyone has their own priorities.”

But the most important lesson didn’t come from pitch meetings. It came from observing what happens after the check clears — in the boardroom. Howard learned from mentors like Bruce Shook how critical board cohesion can be. “The way Bruce ran board meetings at Intact and Vesper — I learned so much from that. It showed me how important the team around the table really is.”

That experience shaped Howard’s belief that board composition matters more than valuation — a contrarian view in a world often obsessed with headline numbers. “I think it’s actually more important,” he says. Having a patient, collaborative board is absolutely critical. Such a board brings valuable perspectives, fosters thoughtful decision-making, and ensures alignment across key stakeholders, which is essential for navigating challenges and driving long-term success. I’m very fortunate with Justin Klein and Cynthia Yee from Vensana and my two independent board members, Bruce Shook and Scott Ward — they’ve seen a lot, and it shows.”

The real value of the right board becomes clear when things go sideways — as they inevitably do in medtech. Howard boils it down to three principles: transparency, trust, and teamwork. “What we do is hard, and we’re crazy to do it in a way — but we love it,” he says. “That’s why it’s so important to have people around the table who understand that, too.”

For founders evaluating competing term sheets, Howard’s advice is direct: don’t chase the highest valuation if it comes with the wrong partners. In medtech — with its long timelines and regulatory complexity — experienced, patient capital always beats short-term optics.

The Top-Down, Bottom-Up Approach to M&A

The same thinking applies to strategic acquirers. Having sat on “the other side” during his time at Boston Scientific, Howard knows how hard it is to break through. “Business development leaders are getting pinged by hundreds of companies every year,” he says. “Don’t waste their time. Develop trust early. Build a reliable message. That’s how you find the right fit.”

For Howard, the most effective M&A strategies combine top-down and bottom-up momentum: building strategic interest over time and real clinical buzz from physicians for your technology. “This is where your physician collaboratives come into play” — not just for product development, but for building market pull.

At the end of the day, acquirers are driven by familiar forces. “It’s all the fear and greed levers,” he adds. “They either want your tech to grow their presence or revenue — or they don’t want someone else to have it because it’s a big threat to them.”
