One the Come Up

Today I was joined by Thor Retlzaff, co-founder of Wasted*, a urine-mining company that turns pee into fertilizer via infrastructure (such as porta potties). Retlaff's career began at Lewis and Clark College, where he majored in anthropology and sociology. Inspiration would come to Retralaff and his cofounders through a series of mountaineering expeditions in the backcountry of the Arctic, Patagonia, Nepal, and in their backyard of Lake Tahoe. On these adventures, they were exposed to the human waste crisis happening in our pristine natural ecosystems — where untreated waste was leaking from pits into the surrounding environment; this originally spawned the nonprofit Do Good Sh*t. In 2020, Retlzaff and his cofounders started Wasted* after realizing that "liquid gold" is filled with vital nutrients such as phosphorus and nitrogen that can be used in our fertilizer. Today, Wasted* is working on expanding beyond the New England states and bringing to market The Can -- which is a fully independent operating porta potty that can create fertilizer all on its own and requires 90% less water than typical porta potties.

Tessa Zimmerman was the inaugural graduate of the Watson Institute's partnership with Lynn University, where she earned a first-of-its-kind bachelor's degree in Social Entrepreneurship. Inspired by her own experience of struggling with anxiety in the classroom and the lack of mental health resources in schools, Zimmerman wrote her college thesis on training and equipping teachers with bite-sized well-being tools. This idea later became her nonprofit, Upstream Education. Today, Upstream partners with individual educators, schools, and districts to equip them with bite-sized well-being tools based on mindfulness and positive psychology practices. Upstream is one of the first nonprofits on the podcast, and Zimmerman and I discuss the business models of nonprofits, how grant funding works, and how being a nonprofit allows Upstream to expand its reach.

Today I was joined by Sandra Takei. Takei's career began at UC Berkeley where she majored in Biology, thinking about becoming a nurse. After realizing she was more interested in creating change at the macro level, Takei transitioned to studying pedagogy. The first guest on the podcast to study at King's College London, Takei obtained her master's in science education and PhD in education research from there. Her PhD research investigated why high school students matriculating in universities choose or don't choose to study physics or modern languages. Today, Takei works at Stanford helping professors tailor their curriculum and classes to become better teachers.

Today I was joined by Christian Brown, co-founder and CMO of Glewee. If Brown wasn’t a founder, I’d venture to say he’d be an oracle. Here’s my evidence: it’s the first day of freshman year for Brown at Danvers High and in Advertising 101 he predicted the growth of micro-influencers in the coming decade (more on that story in the podcast). As a junior, he started laying the foundations of Glewee as just an idea for a clothing company for a DECA project, he launched the company his senior year and kept it during college, eventually selling thousands of items and using the profits to fund his travels and influencer network. Suggestion here: DECA needs an incubator arm. Today, Glewee is a marketplace for brands to find small to medium sized influencers and create campaigns. The first guest that completed undergrad in Chicago (DePaul University) this podcast is also good for those thinking to further their education in Chicago.

Geri Kirilova is a partner at Laconia Capital, an early-stage venture capital firm investing in technology companies transforming established industries. In this conversation, Kirilova reflects on her path from NYU Stern to helping build Laconia, why she chose an unconventional career over a more traditional route, and the role luck, failure, and relationships have played along the way. She also discusses her approach to mentorship, the value of putting yourself in positions to get lucky, and her move from New York to Zurich, where she sees an emerging technology ecosystem and an opportunity to bridge European startups with the U.S. market.

Today I was joined by Mitchell Hora, Founder and CEO of Continuum Ag, a company that uses soil-health data and its TopSoil platform to help farmers improve their soil and profitability. Hora’s career began at Iowa State (also included in this discussion, a list of all the reasons why Iowa State is better than the University of Iowa). Continuum Ag was founded in 2015 as an agricultural consulting company focused on soil-health testing before expanding into agricultural data and technology. Today, its TopSoil platform helps farmers organize farm data, measure the carbon intensity of their crops, and certify lower-carbon grain, which can create opportunities for farmers to receive premiums through biofuel and sustainability markets.

The first Swede on the podcast, Hamza Qadoumi is a co-founder of Ecobloom, a Stockholm-based AgTech company that specializes in crop-monitoring technology. Qadoumi’s career began at KTH Royal Institute of Technology, where he obtained his degree in mechanical engineering. Further, as just the second guest to attend university in the Netherlands, Qadoumi obtained his master’s degree from Delft (as a side note, he now considers the Netherlands a second home)! Ecobloom was founded in 2018, initially developing EcoGarden, a miniature greenhouse and aquaponics system designed for growing food at home. The company later shifted its focus toward commercial growers with EcoSense, a crop-monitoring platform that uses cameras, sensors, and AI to identify plant stress and disease and recommend potential actions. Today, Ecobloom’s technology is used by farms across 12 countries, with the broader goal of making food production more efficient and sustainable.

An interesting episode on modern slavery.

Griffel’s career began at NYU, where he double majored in philosophy and finance (the first guest to study either major and to attend NYU). Beginning his career in 2010 as Head of Marketing at appssavvy, he led company-wide marketing initiatives before founding The Front Labs in 2011, a product-focused incubation lab in New York. In 2013, he co-founded One Month (YC ‘13), serving as CEO and later Chairman through 2021, building it into an online learning platform focused on accelerated technical and entrepreneurial skill development. He went on to co-found Ophelia (YC ‘19) in 2019, where he served as President and COO through 2023 and now continues as Board Observer, while also taking on senior advisory and executive roles at Invisible. Alongside his operating work, he has been involved in academia at Columbia Business School, where he became an Assistant Professor of Professional Practice in 2025. He is currently completing his MBA at Columbia while continuing his work in AI, healthcare, and entrepreneurship education. Further, Griffel is the third NJ native on the podcast!

Today I was excited to be joined by David Marella, Senior M&A Associate at BakerHostetler. Always one for superlatives, I would like to recognize Marella as the first Ocean County native on the podcast. Something of a hometown hero, Marella began his education at Toms River East High School. As an undergraduate student, Marella experienced a change of pace at Rutgers University where obtained his bachelor’s in Economics and Political Science; he obtained his JD at Seton Hall Law School in 2015 where he graduated Cum Laude. David Marella began his legal career as a Corporate Associate at Gibbons P.C. in Newark, where he worked from 2016 to 2017 and then returned after a six-month stint in government service. In 2017, Marella served as an Advisor to the Executive Director of the President’s Commission on Combating Drug Addiction and the Opioid Crisis within the Executive Office of the President. He then resumed his corporate law practice at Gibbons before clerking for Paul B. Matey at the United States Court of Appeals for the Third Circuit in 2019. After completing his clerkship, Marella returned to Gibbons as a Corporate Associate and remained there until 2021. He subsequently joined Squire Patton Boggs as a Corporate Associate in New York, where he worked for nearly three years before moving to BakerHostetler in 2024. He currently serves as a Corporate M&A Associate at BakerHostetler in New York, advising clients on mergers and acquisitions and other corporate transactions.
