In this live episode from the LSI conference, Etienne Nichols sits down with Justin Bushko—known as the "MedTech Man" and author of Medical Device Fireside Chats—to dive into what separates thriving medical device companies from those that fail.

From costly engineering missteps like ignoring tolerance stack-ups to the human factors issues that derail usability in the OR, Justin shares battle-tested advice based on his experience reviewing hundreds of device designs. He also delivers a wake-up call to startups overly focused on licensing or acquisition as the endgame. Whether you're an engineer, founder, or CEO, this episode offers critical insights into how to build a product that works—and a company that lasts.

Standout Quotes

“If your partners can’t explain how and why they did your tolerance analysis, they probably didn’t do it right—and it’ll cost you nine months later.”

—Justin Bushko, on the hidden dangers of relying too heavily on outsourced design partners.

“Founders aiming for a quick exit send the wrong message. Build something sustainable. Acquisition should be a byproduct—not the goal.”

—Justin Bushko, challenging the exit-first mindset common in early-stage MedTech.

Top Takeaways

DFM & Tolerance Analysis Are Non-Negotiable: Skipping detailed design-for-manufacturing and tolerance stack analysis often leads to failure right before tooling and commercialization—when funds are already tight.
Human Factors Must Be Built-In Early: Surgeons may not use your product as intended. Validate with a wide range of KOLs to uncover unintended use or misuse.
Test for High-Risk Use Cases Early: For devices like inserters, test mechanical thresholds that could lead to field failures. Don’t wait until post-market feedback.
Understand Economic Buyers, Not Just KOLs: A surgeon’s support doesn’t guarantee adoption. You need champions who can advocate to hospital boards and procurement teams.
Stop Chasing Exits—Build Real Companies: Investors and acquirers see through the “quick flip” mentality. A sustainable business model attracts more serious interest.
