    S13E13 - What Does a Billion-Dollar Exit Really Look Like?

    How Does Water-as-a-Service Drive Billion-Dollar Exits in Infrastructure Investment? 🙌 Supporters 🙌 A big thank you to my partner SimpleLab: https://link.dww.show/simplelab ⬇️ IN THIS VIDEO ⬇️ Seven Seas Water Group is a vertically integrated water infrastructure platform that designs, builds, finances, operates, and maintains water and wastewater treatment facilities under long-term service agreements. The company recently completed a successful exit from Morgan Stanley Infrastructure Partners to EQT Infrastructure, operating over 210 water-as-a-service contracts across the Caribbean and United States with particular expertise in brackish water desalination and decentralized treatment systems. Henry Charrabe is the CEO of Seven Seas Water Group who led the company through a successful four-year transformation and exit, previously serving in executive roles at Fluence Corporation, and is recognized for pioneering the application of water-as-a-service business models in US municipal and industrial markets. 🌶️ KEY SPICES 🌶️ 💰 Vertically integrated platform - Seven Seas handles design, engineering, financing, construction, and operations in-house, eliminating margin stacking for lower costs and faster execution than multi-partner competitors ⚡ Proven track record at scale - 210+ active water purchase agreements with 15-30 year terms demonstrate repeatable success new entrants cannot easily replicate 🔄 Patient capital meets expertise - The exit proves infrastructure investors holding 4+ years combined with deep water knowledge generate exceptional returns in underinvested US infrastructure 📊 Public vs private dynamics - Public water equities offer lower risk and liquidity; private funds deliver superior returns for patient capital—both forming a necessary growth ecosystem 🥜 IN A NUTSHELL 🥜 Why is water-as-a-service winning? Performance-based contracts align incentives—investors only get paid when delivering contracted water quality and quantity. What makes the US market attractive? Massive infrastructure underinvestment, creditworthy municipal off-takers, and decentralized systems create exceptional deployment opportunities. How do private and public returns differ? Private water investments achieve 10x returns with patient capital, while public equities deliver 14-15% annually with lower risk and immediate liquidity. Why fewer IPOs today? Cyclical markets favor private-to-private exits when strategic buyers offer better valuations than public market multiples. What's the biggest opportunity? Reducing waste beats new supply—California loses 32% to inefficiencies, making conservation more economically attractive than desalination. #️⃣ Mentioned Links #️⃣ Seven Seas' website Loughlin Water Partners Orange Ridge Capital Robin Castelli's book ⏰ TIME CODES ⏰ 00:00 Live from NYC's Climate Week 04:00 Henry Charrabé (Seven Seas Water) 25:49 John Rosenberg (Loughlin Water Partners) 40:08 Robin Castelli (Orange Ridge Capital) 50:01 Closing Hosted by Ausha.

    SPECIAL: How SOURCE Lost Everything in Just 12 Months

    🤔 What Happened to Source Global's Water-from-Air Technology? 🙌 Supporters 🙌 A big thank you to my partner SimpleLab: https://link.dww.show/simplelab My best water tech analysis straight to your inbox SOURCE (formerly Zero Mass Water) produced drinking water from air using solar-powered Hydropanels. Founded in 2015 by Cody Friesen, it raised $270 million, becoming one of water tech's most-funded companies. 🥜 IN A NUTSHELL 🥜 What was Source Global's core technology? Solar-powered Hydropanels that extract drinking water from atmospheric humidity, requiring no electrical or water infrastructure. Why did the company fail despite massive funding? Ran out of cash after failing to raise funds, faced major quality issues from Malaysian manufacturing, and had unsustainable costs versus traditional water delivery. What were the main product problems? High failure rates within 2-3 years, frequent fan and battery breakages, and warranty quietly reduced from 10 to 5 years. Did Source attempt a business pivot? Acquired Proud Source Water and launched Sky Water, building Hydropanel farms to produce canned atmospheric water at scale. What remains of Source Global today? The founder and executives left in early 2025. Hydropanels and Sky Water are out of stock, but the acquired Proud Source Water business continues operating. #️⃣ Mentioned Links #️⃣ SOURCE's SEC filings (over the years): Source on Glassdoor Source's troubles in Allensworth My own interview with Source, four years ago Source's website (still active) Cody Friesen's LinkedIn profile Proud Source Water's website The Marianna Hydropanel Farm on Google Maps Thunderf00t's original video Hosted by Ausha.

    Why 32 Companies Fight Over 24 Electrochemical Oxidation PFAS Destruction Deals

    How Do 32+ Electrochemical Water Oxidation Technologies Compete for PFAS Destruction Market Share? Listen to this! More #water insights? Connect with me on Linkedin: https://www.linkedin.com/in/antoinewalter1/ 🙌 Supporters 🙌 A big thank you to my partner, Georg Fischer: https://www.gfps.com/com/en/products-solutions/solutions/design-prefabrication.html#! How Do 32+ Electrochemical Water Oxidation Technologies Compete for PFAS Destruction Market Share? Electrochemical Water Oxidation is an emerging treatment technology that uses electrical current to break down persistent contaminants like PFAS in industrial wastewater. With 32 identified companies developing proprietary systems—17 specifically targeting PFAS destruction—this crowded market represents both intense competition and strong validation of a rapidly growing industrial need. Antoine Walter is a water technology analyst and podcast host who has interviewed nine electrochemical oxidation companies, conducted comprehensive market research across 32 players in the space, and provides strategic insights for entrepreneurs, investors, and water industry executives navigating this competitive landscape. 🌶️ KEY SPICES 🌶️ ⚡ Power Density Range: Technologies span three orders of magnitude (100-10,000+ A/m²), with higher densities potentially enabling more compact treatment systems 💎 Electrode Materials: Boron-Doped Diamond (33%) and Titanium suboxide (28%) lead among PFAS-focused companies, with Mixed Metal Oxide dominant overall 🎯 Market Maturity: 53% of PFAS-targeting companies operate at TRL 8 with only two at full commercial deployment (TRL 9) 🧪 Defluorination Proof: Four companies have achieved third-party verified >90% defluorination, with half reporting complete PFAS destruction capabilities 🏭 Minimal Chemistry: 58% operate with minimal chemical addition, and 83% self-clean through electrical reversal or direct capacity 🥜 IN A NUTSHELL 🥜 What's the actual market size? Only an estimated 250 of 10 million global industrial facilities have addressed PFAS in wastewater, with perhaps 24 choosing electrochemical oxidation—creating fierce competition for limited installations. How do electrode materials differ? Boron-Doped Diamond offers superior performance but higher costs, while Mixed Metal Oxide and Titanium suboxide provide alternatives, with some companies opting for sacrificial anodes to reduce expenses. What determines system performance? Power density, pH tolerance (46% work at neutral pH), electrode lifetime, and reactor design collectively influence treatment efficiency and operational costs more than any single factor. Are these technologies deployment-ready? Most companies (TRL 7-9) have moved beyond lab-scale, though only Axine and AECOM have reached full commercial deployment with multiple installations. What's the investment opportunity? The collective $120M raised across startups represents capital-efficient validation, with regulatory pressure intensifying and the addressable market potentially growing 10x within three years.

    S13E12 - Can We Actually Afford to Clean Up Forever Chemicals?

    How Can We Afford to Remove PFAS from Our Environment When Treatment Costs Exceed Global GDP? 🙌 Supporters 🙌 A big thank you to my partner SimpleLab: https://link.dww.show/simplelab ⬇️ IN THIS EPISODE ⬇️ PFAS (per- and polyfluoroalkyl substances) are persistent synthetic chemicals used in countless everyday products that contaminate drinking water, wastewater, and the environment. These "forever chemicals" accumulate irreversibly in our bodies and ecosystems, creating mounting health risks for current and future generations while presenting unprecedented economic and regulatory challenges. Dr. Ali Ling is a professor at the University of St. Thomas specializing in PFAS management and wastewater treatment, with a decade of consulting experience helping industrial and municipal facilities address emerging contaminants, and expertise in big-picture systems thinking for environmental risk assessment. 🌶️ KEY SPICES 🌶️ 💰 Cost-Effective Approach - Source reduction is 1,000 times cheaper than environmental cleanup, with upstream industrial controls costing hundreds versus millions of dollars per kilogram of PFAS removed 🔬 Technology Expertise - Comprehensive knowledge of GAC, ion exchange, destruction technologies, and emerging treatment solutions across drinking water, wastewater, and industrial applications 📊 Data-Driven Strategy - Evidence-based analysis showing that removing PFAS at current production rates would exceed global GDP, making source control the only viable path forward 🎯 Risk Prioritization - Understanding that drinking water represents less than 20% of human PFAS exposure, with diet and indoor dust contributing significantly more to health risks 🌍 Future-Focused Thinking - Emphasis on persistence as a critical factor, recognizing that today's PFAS releases create irreversible accumulation threatening future generations 🥜 IN A NUTSHELL 🥜 Why is cleaning up PFAS from the environment economically impossible? Removing PFAS from the environment at the rate we produce it costs millions of dollars per kilogram and would exceed global GDP, while upstream source control costs only hundreds to thousands of dollars per kilogram. What's the biggest misconception about PFAS treatment? Most people focus on drinking water cleanup as a past problem, but we're still actively producing massive amounts of PFAS today, and drinking water represents less than 20% of human exposure to these persistent chemicals. Should utilities treat PFAS in wastewater effluent? Treating municipal wastewater effluent is extremely expensive and environmentally impactful, whereas addressing industrial discharges and landfill leachate at their concentrated source points is far more cost-effective and logical. How do we prevent regrettable substitution when phasing out PFAS? The European Union is implementing better frameworks that assess both persistence and toxicity before approving chemicals, while companies like IKEA and H&M have successfully phased out PFAS entirely from their supply chains. #️⃣ Mentioned Links #️⃣ Ali Ling's LinkedIn profile Ali's paper on the costs to remove PFAS from the environment Hosted by Ausha.
