Clarke: building software good enough to look like magic.
Shreyans Chopra
Shreyans Chopra is the founder and CEO of Mstack, an AI-native specialty chemicals company based in Houston that helps North American and global buyers source custom chemicals from a diversified manufacturing network. A chartered accountant turned BCG consultant turned Lightspeed India investor, he started Mstack in July 2022 and scaled it to more than 100 enterprise customers and operational profitability, raising a $40 million Series A led by Lightspeed and Alpha Wave in 2024. In 2025 the company launched Chemstack AI, an R&D platform that compresses molecule synthesis timelines from roughly 18 months to days.
Sumer Johal
Sumer Johal is a technology executive and entrepreneur with more than 25 years building digital-first organizations across agtech, bioenergy, semiconductors, financial services, and consumer retail. He grew up in a farming family in Punjab, India, studied computer science and electrical engineering at MIT, and has spent the past decade focused on food and agriculture. He founded the food-industry big-data company Agralogics, launched and led AgStack at the Linux Foundation, ran the precision-agriculture company Semios (which rebranded as Almanac), and became CEO of Full Harvest, the B2B produce marketplace, as it moved into AI-driven agentic orchestration for the food supply chain.
Egor Kirin
Egor Kirin is the founder and CEO of Agro.Club, a full-stack B2B agriculture marketplace that connects input manufacturers, distributors, farmers, and grain buyers across Europe, South and North America. After nearly a decade of executive roles at Monsanto and a stint leading marketing at EuroChem, he left corporate agriculture at 31 to build a technology and embedded-finance platform aimed at making the grain supply chain more efficient, transparent, and secure.
Mike Shebat
Mike Shebat is the co-founder and CEO of Traba, a New York-based labor marketplace that supplies vetted on-demand workers to warehouses, distribution centers, and light industrial employers. He started the company in 2021 after seeing, from inside a McMaster-Carr shipping floor and later Uber Eats, how often temp workers simply don't show up. Traba has raised roughly $46 million from Founders Fund and Khosla Ventures, and Shebat, a Forbes 30 Under 30 honoree, runs it on a famously intense in-office schedule.
Zachary Irwin
Zachary Irwin is the co-founder and CEO of Downstream, a Dallas-based marketplace that lets contractors book equipment rentals, dumpsters, portable toilets, and site services with a few taps - the way you might order a pizza. Started in 2022 as 'Trash Gurus' and rebuilt into an AI-driven procurement platform with 100,000+ listings, Downstream raised an $8M Series A in November 2025 co-led by Brick & Mortar Ventures and Moneta Ventures. Irwin came to construction's least glamorous corner from an unlikely place: years as a healthcare-software (Epic) consultant building oncology and pharmacy systems across 22 states.
Dallas Hogensen
Dallas Hogensen is the co-founder and CEO of Felux, a Cleveland-based digital marketplace and operating platform for the steel and metals industry. A ranch-raised Oregonian and former college football player turned serial startup operator, he scaled Lyft Business toward $1 billion in revenue and co-founded two companies (Liveli and Signal HQ) before relocating his family to Ohio to digitize a $2 trillion industry famous for handshakes and fax machines. Under the irreverent banner #makingsteelsexy, he has grown Felux's platform volume from roughly $10M to hundreds of millions in transactions, raised more than $24M in venture capital, and set out to put Cleveland back on the map as a hub for industrial technology.
Martin Hunt
Martin Hunt is the co-founder and CEO of Garage, an AI-powered marketplace where fire departments, ambulance services, and local governments buy and sell their most expensive gear - fire trucks, ambulances, rescue equipment, and surplus apparatus. A volunteer firefighter at 15 in Delaware who later worked in private equity at Goldman Sachs, Hunt built Garage after a friend in the fire service asked for help unloading old equipment and he found no good way to do it. Out of Y Combinator's Winter 2024 batch, Garage now operates across all 50 states and raised a $13.5M Series A in August 2025, bringing total funding to $18M.
Matt Garippa
Matt Garippa is the co-founder and Chief Business Officer of Order.co, the New York B2B purchasing platform formerly known as Negotiatus. A former fixed income trader who pivoted from Wall Street trading desks to building software, he and his brother Zach started the company in 2016 after a friend running a CrossFit gym complained about the grind of ordering supplies. Today Order.co helps hundreds of finance and operations teams - including WeWork and SoulCycle - consolidate purchasing, payments, and spend control, and Matt leads its business strategy, partnerships, and analytics, now centered on AI-driven procurement.
Nihad Rahman
Nihad Rahman is the CEO of ezCater, the Boston-founded online marketplace that turns office lunch into logistics across 100,000+ restaurants. He joined in 2022 as CFO after two decades in finance at JPMorgan Chase and General Electric, stepped in as interim chief in January 2025, and was handed the permanent job that May - succeeding 16-year co-founder Stefania Mallett. He runs a roughly 850-person company from Bronxville, New York, commuting to the downtown Boston headquarters rather than the other way around.
Ali Amin-Javaheri
Ali Amin-Javaheri is the co-founder and CEO of Knowde, the B2B digital marketplace and data platform transforming how the $5 trillion global chemicals industry does business online. With 11 years of experience at ChemPoint - where he helped scale the chemical distribution startup to over $400M in revenue - Ali built Knowde from a PowerPoint vision into a platform hosting 8,000+ supplier storefronts and 230,000+ chemical products. Backed by Sequoia Capital, Coatue, and Sound Ventures (Ashton Kutcher's fund), Knowde has raised $180.8M total, including a $60M Series C in August 2024. Ali's drive is deeply personal: his father Mehdi fled Iran in 1985 and struggled to find work commensurate with his chemical engineering degree, and Ali grew up reading chemistry trade magazines, determined to modernize an industry built on relationships and paper catalogs.
Mohamed Batterjee
Dr. Mohamed Mazen Batterjee is the Co-Founder, CCO, and investor behind Aumet, an AI-first procurement operating system reshaping pharmaceutical supply chains across the Middle East. A scion of one of Saudi Arabia's oldest pharma dynasties, he parlayed a DBA from IE Business School and 15+ years running Batterjee Pharmaceuticals into co-founding a platform that now connects 12,000+ pharmacies, 1,000+ suppliers, and has processed over $1 billion in GMV. Aumet closed a $12M Series A in May 2026, bringing total funding to $21.84M.

With a pharmacy background from the University of Jordan, Jaber has helped grow Aumet into an AI-first procurement platform serving 12,000+ pharmacies and 32 hospitals across the MENA region, processing over $1 billion in GMV and raising $21.84M in total funding.
Marcus Shen

A former Yahoo! VP of Corporate Development and KKR advisor, Shen joined B-Stock as CFO in 2019, rose to COO, and took the CEO role in March 2022. Under his leadership, B-Stock has become a defining force in the recommerce economy, selling 160 million units annually and keeping nearly 300,000 tons of inventory out of landfills.
