Digitization and Smart Water? 💪 Get the Water Market pulse for free. In one hour per week, while you do the dishes! 📈 We talk water investment, water tech, water entrepreneurship and water market with entrepreneurs, thought leaders, book authors, scientists, investment funds, VCs, and C-Level experts from water majors. ➡️ Leverage their insights, advice & experience and ensure to stay on top of best practices 🗓️ Tune in every Wednesday (don't miss out! 😅) 🌐 Find all the detailed episode notes, interviews, infographics, and more at http://dww.show Currently in its 10th Season, the "(don't) Waste Water" podcast has already welcomed around 250 guests from Water Majors (SUEZ, Veolia, Jacobs, Xylem, Kemira, Evoqua, Aquatech, SKion Water...), Scale-Ups (Cambrian Innovation, Epic Cleantec, Gradiant, Liqtech, 374Water, Gingko Bioworks...), Start-Ups (Puraffinity, KETOS, 120Water, ZwitterCo, Membrion, Source...), Universities (Berkeley, the Columbia Water Center), Investment Funds (Sciens Water, Mazarine, Burnt Island Ventures...), Business Accelerators (Imagine H2O, Elemental...), Book Authors (Seth Siegel, David Sedlak, David Lloyd Owen...) or Market Intelligence Companies (BlueTech Research, Global Water Intelligence, World Bank, OECD, Isle Utilities...). Or simply water legends like Gary White, Mina Guli or Andrew Benedek! On the "(don't) Waste Water" podcast, I strive to make the Water Industry easy to understand for everyone, starting with water professionals, executives, and investors. Hence, he opens the microphone to seasoned, inspirational water experts to discuss their field of excellence. No one can claim an all-around in-depth understanding of a matter as complex as Water. But piece by piece, you can rebuild the puzzle. With curiosity, patience, and passion, Antoine Walter explores topics such as Advanced Treatment Technologies, Water-Energy Nexus (Hydrogen, Lithium...), PFAS removal, Nature-Based Solutions, Wastewater Reuse, Distributed Water Treatments, Water Finance, and Water Entrepreneurship. I actually firmly believe that regular listeners of the "(don't) Waste Water" podcast may, in the end, claim a "Water MBA!" A particular field of interest is how innovation forms, grows and gets widely adopted in a complex and conservative field like the Water Industry. This may be one of the keys to achieving the United Nations Sustainable Development Goal n°6 - #SDG6. Oh, and in short, about me: I'm a water engineer turned avid student of the water business, market, finance, and tech. I'm married, a happy father of three, and I'm French (nobody's perfect 😅).

    H2O Innovation is a Quebec-based water solutions company founded in 2000. Through strategic M&A, it evolved from a membrane filtration startup into a diversified platform with four pillars: systems, specialty chemicals, operations & maintenance, and water infrastructure development—with the mission to Simplify Water.

    Guillaume Clairet is COO at H2O Innovation and GP at the Cycle H2O fund, with 20 years steering the company's M&A-driven transformation from startup through 18+ acquisitions to a private equity-backed platform targeting $1 billion by 2030.


    🌶️ KEY SPICES 🌶️

    🔧 Four integrated pillars—systems, chemicals, O&M, and water infrastructure development—enable full lifecycle customer relationships from CapEx through recurring revenue

    📈 Proven M&A machine with 90%+ acquisition success rate versus the industry standard where two-thirds of deals fail

    🌍 Global distribution network serving OEMs across Turkey, Peru, Chile, and Australia with specialty chemicals and components

    💧 Water reuse leadership through the Water Infrastructure Development division offering turnkey solutions with no upfront capital under long-term contracts

    🤝 Patient private equity partnership with Ember Capital allowing accelerated growth while preserving management continuity and institutional investor alignment


    🥜 IN A NUTSHELL 🥜

    How did H2O Innovation transform from a startup to a platform company? Starting as a membrane filtration technology company in 2000, H2O Innovation strategically shifted focus from pure CapEx sales to recurring revenue streams by acquiring specialty chemicals companies PWT and Genesis, then rolling up five O&M contractors across North America.

    What makes their acquisition strategy different? Rather than relying on investment banking processes, H2O Innovation sources most deals directly through trade shows, customer networks, and industry relationships—prioritizing cultural fit, synergy validation, and fair valuations over competing in auctions.

    What changed after Ember Capital's take-private transaction? The 2023 privatization brought renewed appetite for bigger swings and faster decision-making while preserving continuity through existing institutional investors CDPQ and IQ rolling over their stakes alongside management remaining invested.

    What is the Water Infrastructure Development pillar? Acquired through NextEra Distributed Water, this fourth pillar offers industrial and institutional clients turnkey water reuse solutions where H2O Innovation finances, builds, owns, and operates decentralized treatment systems under 30-35 year contracts.

    Where is H2O Innovation heading by 2030? The company targets over $1 billion in revenue through continued tuck-in M&A, exponential growth in water processing agreements, and geographic expansion.

  • The Future of Water Tech VC: Why Specialists Are Finally Emerging.
    Dec 17 2025

    How is Cycle H2O (a new Water VC) De-Risking Early Stage Water Tech Investment?

    Cycle H2O is a Canadian water-focused venture capital fund investing $500K-$2M checks in early-stage water technology companies. The fund targets 12 portfolio companies across industrial, municipal, and agricultural water sectors with $30 million ready to deploy.

    Simon Olivier is a senior partner at Cycle Capital and head of the Cycle H2O Water Fund, bringing 30 years of corporate experience, including building GE's renewable energy business from the ground up, acquiring Enron's wind assets in 2001, and now applying energy sector investment lessons to water tech & the water VC field.


    🌶️ KEY SPICES 🌶️

    🔬 Three-headed de-risking structure: Cycle Capital brings VC management expertise, H2O Innovation provides market intelligence across 75 countries, and the fund team delivers strategic guidance as a "copilot investor"

    ⚡ Energy-to-water playbook: 30 years of renewable energy experience reveals water tech is following the same arc—but with higher stakes since water has no substitute

    💼 Business continuity focus: Invests in B2B solutions where industrial users pay for water efficiency because it directly impacts their bottom line, not just compliance

    🎯 Exit-first valuation: Maps potential exits before cutting checks to avoid down rounds—seeking the "Goldilocks valuation" where both founder and investor stretch

    🌍 Impact without compromise: Treats environmental and financial returns as inseparable, positioning water as a strategic business asset rather than a feel-good cause


    🥜 IN A NUTSHELL 🥜

    Why focus on early-stage water tech? The greatest impact and value creation happens early, but the risk is high—hence the unique fund structure with strategic partners who provide due diligence support and accelerate time-to-market for portfolio companies.

    How do you compress the industry's notorious 12-16 year adoption cycle? By investing in companies addressing urgent market fundamentals like the Legionella detection company Bio Alert, and leveraging H2O Innovation's global network to fast-track pilots and distribution partnerships.

    What makes a quick "no" for investment? Missing barriers to entry like IP, undifferentiated "me-too" products, no clear roadmap to monetization, or incomplete founding teams—though exceptional strength in one area can offset weakness in another.

    Why avoid policy-dependent business models? Regulations change overnight; instead, the water VC targets industrial users where water efficiency drives business survival, making adoption a financial imperative rather than a compliance checkbox.

    What returns can water tech deliver? The fund targets 10x returns as achievable across the portfolio, expects two to three zeros from twelve investments, and bets that rising water scarcity will drive up valuations as water becomes properly priced as a finite resource.

    🧴 L'Oreal's Burgos "waterloop factory" reuses 100% of process water for Kerastase production

    🧪 Hungarian startup Cycle ferments sewage sludge into bio-acid cleaners shipped worldwide


    🥜 IN A NUTSHELL 🥜

    Can you really eat products from desalination waste? Aqualia's Alma de Mar table salts and UAE-grown Salicornia demonstrate that brine valorization creates food-safe, even gourmet products through controlled crystallization and aquaponic farming.


    How are beverage companies using wastewater? H2O Innovation, Epic Cleantec, and Singapore's NEWBrew produce beers from purified wastewater, while Good Vodka upcycles 15 million tons of annual coffee cherry waste and Old Humble proofs whisky with collected Texas rainwater.


    What makes water-smart clothing different? Everlane's Saitex partnership recycles 98% of process water, Triarchy replaces chemical bleaching with ozone, and Girlfriend Collective turns plastic bottles into sportswear while capturing microplastics.


    Which home products close the water loop? Porcelanosa ceramics operates zero liquid discharge, EnviroCopy paper circulates water 30 times per production cycle, and Vuna's Aurin turns urine into nitrogen fertilizer now scaling across Europe.

Exactly what it says on the tin. A great resource for people interested in wastewater or who want to keep up with recent developments particularly from an environmental perspective. Only negative is that sometimes mic quality can be noticeably low, though it varies depending on the speaker and does not impact ability to understand.
