A talk in a trig class, and everything after
Tracy MacNeal was fifteen, sitting in a high-school trigonometry class, when a woman engineer walked in to describe her work. It was the kind of ordinary event that turns out to be a hinge. MacNeal enrolled at The Cooper Union in New York City to study chemical engineering, and she has been building things ever since.
That origin - a single visitor, a single conversation - has stayed with her. It is the reason she talks openly about representation not as a slogan but as a practical mechanism. Careers get made and unmade by who happens to walk through the door. Hers exists, in part, because someone bothered to show up.
After Cooper Union she went to Merck & Co., where from 1997 to 2001 she worked as a new product analyst and process engineer. The job took her between New York City and London before she was twenty-five, an early lesson in operating across borders and functions. She later earned an MBA from Duke University's Fuqua School of Business, pairing the engineer's toolkit with the operator's. Two toolkits, and a habit of using both at once.
From 2011 to 2017 she was chief strategy officer and EVP of sales and marketing at ATW Companies. From 2017 to 2019 she served as President of Diagnostics & Digital Health and chief marketing officer at Ximedica, the product-development firm. Then, in 2019, she took the top job at Materna Medical, a women's health technology company based in Mountain View, California.
Across those moves the sector kept changing - pharmaceuticals, then diagnostics, then digital health, then devices - but the shape of the work did not. MacNeal keeps choosing the harder problem: the product that is complicated to explain, the category that does not yet have a name, the market with no obvious competitor because no one has built it. She is candid about the cost of that choice.
On building where the map runs out
If you're working in a space that's underdefined and you are genuinely a first mover, it's going to be expensive.
The number one thing that investors are listening for is when they are going to get their money back.
If you succeed, you'll probably be doing it for 10 years. You better love it - because it's a journey.
If we're not focused on the patient's best interest, the deal is no good.
Those lines capture a leader who refuses to romanticize the startup path. She talks about a decade-long marathon, not an overnight sprint, and she leads investor conversations with financial clarity rather than mission-washing. It is a form of respect - saying the quiet part out loud so that everyone in the room knows the terms of the deal.
The same directness shows up in a story she tells against herself. Early in her career she vented her frustration at a customer. He never forgave her. The moment taught her that words are a kind of inventory, best spent with care, and she now puts real energy into honoring the humanity of everyone she works with. It is a small anecdote that explains a lot about how she runs a company.
Beyond Materna, MacNeal serves on the board of AdvaMed, the medical technology industry association, and chairs its Women's Executive Network. She frames that work the way she frames the trig-class story: you open a door, and then you hold it open for the next person. Running a company and building a national network for women leaders are, in her telling, the same project seen from two angles.
What ties it together is temperament. Colleagues and interviewers describe someone intellectually humble enough to name her own gaps and decisive enough to move anyway, a storyteller who happens to have an engineer's respect for evidence. She will do the unglamorous foundational work herself - aligning experts, publishing the white paper, building consensus - before she asks anyone to buy. In markets that don't exist yet, that patience is the whole game.
