Jeff Elkins Has Spent 30 Years Learning What Tiny Tools Must Get Right
Before Jeff Elkins became a repeat medtech CEO, he learned to scale products, read clinical data and worry about the expensive mistakes nobody else could see. His career is a practical study in how engineering judgment becomes company judgment.
Benjamin Claman Put the Blimp Back to Work
The Alaska-raised engineer started with cargo, found a market in attention, and turned an old aircraft into a new kind of media platform.
He Spent a Decade Installing Turbines. Then He Tried to Make Venezuelan Commerce Click.
Alejandro Flores-Hernández took a field engineer’s appetite for systems into Maracaibo’s messy mix of payments, delivery and online shopping. QUIK is his attempt to make the whole machine run from one tap.
Christopher South Built a Three-Hour Answer to Advertising’s Expensive Question
An engineer, an abandoned startup and a rush of sales calls became Spot Trender. Christopher South’s career is a study in how to turn a failed first draft into a faster way of listening.
Matthew Irvin Is Teaching the Grid to Use Time
The Maplewell Energy co-founder spent his career around power plants and utility constraints. Now he is betting that smarter timing - from refrigerated drinks to distributed batteries - can make the electric system more flexible.
Deep Chakraborty Is Building Memory for the Rooftop
He arrived in America with one suitcase, a sitar and a ticket he still keeps. Decades later, Deep Chakraborty is trying to give every solar roof something the industry has often misplaced: a continuous memory from first sketch to long-term performance.
Melanie Allen
Melanie Allen is the Senior Vice President and Chief Marketing Officer of Brooks Running, the Seattle-based, Berkshire Hathaway-owned performance running brand. A first-generation college graduate with a mechanical engineering degree from Michigan State University, she took an unusual route into marketing - from vehicle climate-control systems at Ford, to Pampers R&D and brand work over 14 years at Procter & Gamble, to coffee innovation at Starbucks, and finally to running shoes. Since joining Brooks in 2017 she has led the brand's global marketing, e-commerce, corporate responsibility and emerging business, helping steer the company through eight straight years of growth to roughly $1.3-1.4 billion in annual revenue and campaigns like the Cynthia Erivo 'Shine Under Pressure' partnership under the 'Let's Run There' platform.
Josh Mackanic
Josh Mackanic is the founder and CEO of CivilGrid, a San Francisco construction intelligence platform that stitches together utility, environmental, and geotechnical site data so engineers stop discovering surprises with a backhoe. A licensed mechanical engineer with a decade inside PG&E and an MBA from Wharton, he has shepherded north of half a billion dollars of gas, electric, and renewable infrastructure into the ground.
Andrej Strojin
Andrej Strojin is the co-founder and CEO of HAVERHILL, a Warren, Rhode Island fine-jewelry house that makes 14k gold, birthstone-personalized pieces to order rather than in advance. A Slovenian-trained mechanical engineer and former Deloitte and Strategy& consultant, he met fifth-generation jeweler Haverhill Leach on a dating app in 2018, married her four months later, and turned her artisan brand into a fast-scaling direct-to-consumer operation. When COVID shut down suppliers before Mother's Day 2020, the couple built a jewelry assembly line in their garage and cut turnaround from seven days to one. Under Strojin the company has quadrupled sales, reached $16M in 2024 revenue, and landed on the Inc. 5000 three years running.
Fletcher Wilson
Fletcher Wilson is the co-founder and CEO of Throne Labs, the company behind the largest network of connected public restrooms in the United States. A mechanical engineer trained at Penn and Stanford, he spent nearly a decade building InterVene, a medical-device startup, before turning his attention in 2020 to a problem hiding in plain sight: the disappearance of clean, accessible public bathrooms. Throne's solar-powered, sensor-equipped units deploy in under two hours, are free to use, and have logged more than a million uses across 20-plus cities. In October 2025 the company raised an initial $15 million Series B led by Brentwood Associates.
Sungwoo Min
Sungwoo Min is the founder and CEO of Nventric, Inc., an Arcadia, California medical device company that designs, develops, and contract-manufactures vascular devices for the neurovascular, electrophysiology, and coronary markets. A Stanford-trained mechanical engineer who cut his teeth on R&D and marketing at Abbott Vascular and later led R&D programs at Johnson & Johnson, he started Nventric in 2019 to build the kind of life-saving catheters, stents, and thrombectomy systems he used to ship at the giants - this time end to end, ISO 13485 certified, with operations in the US and South Korea. He is a named inventor on multiple US patents for mechanical thrombectomy devices.
Valentina Ratner
Valentina Ratner is the co-founder and CEO of AllSpice.io, the 'GitHub for hardware' that brings version control, collaboration, and automated design review to the engineers who build PCBs, schematics, and bills of materials. An Argentina-born mechanical engineer turned Amazon PM turned Harvard MS/MBA, she launched AllSpice after watching brilliant teams build complex machines on archaic, file-shuffling workflows. In June 2025 she raised a $15M Series A to take the company's AI design-validation agent out of private beta, with customers spanning Blue Origin, Bose, and Tools for Humanity.
Anna-Katrina Shedletsky
Anna-Katrina Shedletsky is the CEO and co-founder of Instrumental Inc., a Palo Alto-based AI manufacturing software company she founded in 2015 after six years at Apple—where she spent 300+ days in Chinese factories debugging manufacturing issues for the iPod and led product design for the original Apple Watch. At Instrumental, she is converting those factory-floor battle scars into software that uses AI and cameras to find defects and eliminate waste on electronics assembly lines, with customers including Cisco, Honeywell, Bose, Meta, and Lenovo. The company has raised $80.3M in total funding and was named Fast Company's #2 Most Innovative Manufacturing Company in 2021. She also founded the Women in STEM Mentorship Program (WISMP) at Stanford in 2013, which now spans multiple universities.
Trae Vassallo
Trae Vassallo is a Stanford-educated mechanical engineer, venture capitalist, and technology leader who co-founded Good Technology (acquired by Motorola for $500M), served as a General Partner at Kleiner Perkins for 14 years investing in companies like Nest Labs and eero, co-founded Defy Partners (raising $151M+ in capital), and now leads business operations and strategy at Apple. She holds 13 patents across technologies and disciplines, and became a pivotal figure in the conversation about gender bias in Silicon Valley after testifying about sexual harassment in the landmark Ellen Pao v. Kleiner Perkins case and co-authoring the influential 'Elephant in the Valley' survey.
