“Some social and humanitarian problems simply cannot be solved with donations or nonprofit structures alone. When the goal requires long-term sustainability, you will not solve it until you bring a market discipline to it. It’s the only way. ”
— Talmage Payne
In this episode, I talk with Talmage Payne, chairperson of TapEffect. He’s an entrepreneur, humanitarian, and investor who has spent much of his career operating in some of the most difficult markets on the planet.
TapEffect is a rural water utility in Cambodia that builds piped water systems for low-income communities. It operates at the intersection of rural infrastructure and blended finance, combining viability-gap grants, patient equity, and bank debt to reach communities most funds ignore.
Talmage has spent more than two decades building commercially viable ventures in environments traditionally dominated by humanitarian aid (like Cambodia, Southeast Asia, Afghanistan, Vietnam, West Africa).
His work spans housing, water, and agriculture, but always starts in the same place: How do you solve a real-world problem and make it last?
At World Vision he led large-scale humanitarian and development programs. Later at Hagar he helped build highly specialized services for women and children recovering from trafficking and extreme abuse.
Then he launched First Finance to provide home loans for borrowers long excluded from formal banking. He also helped build a straw mushroom buying platform that raised rural incomes by offering a reliable market and consistent prices.
Each venture showed what works. And the real friction point: building infrastructure is easy, but keeping systems working is hard. Hand pumps break. Public wells sit idle. “If you don’t have revenues, who’s going to maintain it and take care of it?”
TapEffect took a different approach. Instead of drilling another grant-funded borehole, they built centralized piping systems stretching 60 to 70 kilometers and serving up to 6,000 households. They priced connections around what local families could afford (often with viability-gap support for poorer homes). And they solved costly water losses using AI-enabled leak detection.
They’ve reached over a dozen villages with chlorinated piped water and are continuing to scale the model in Cambodia. Patient capital from World Hope and Habitat’s Shelter Venture Fund de-risked the early buildout. Clarion Newlife Capital backed the commercial model. And today, commercial banks are willing to lend into new TapEffect systems.
That way of thinking shapes how he approaches impact investing. It’s not enough to mean well. You need to ask hard questions on both sides of the ledger.
Talmage often explains that through his “two-wallets” idea: people demand discipline and returns with their investment wallet, but relax expectations with their philanthropy wallet. They end up giving to good stories without testing sustainability or accountability.
He argues that those worlds should overlap. We need investment discipline inside our giving and impact values inside our investing. Blended finance turns that idea into practice:
– First, grants take early risk
– Then, patient equity gets systems running
– At the end, commercial debt scales what works
In Cambodia, he’s also met people who just can’t wrap their heads around TapEffect because it’s a business. They insist the utility must be community-owned. His response is simple: “Go live with a community-owned system. You won’t like it.”
Systems last only when capital is accountable, revenue is measured, and outcomes are real.
TapEffect focuses on tangible outcomes: how many households are connected, how reliably systems keep delivering clean water over time, how much revenue customers generate by using it, and how many hours of manual water collection families are able to eliminate.
Talmage has lived through enough cycles to know that structure matters more than slogans. He’s seen aid programs collapse without follow-up. He’s watched training schemes underperform because they ignored local incentives. He’s helped build platforms that changed rural incomes.
The pattern is always the same: structure creates value, and value reshapes behavior.
Talmage’s work shows that impact isn’t an idea on paper. It’s a system that has to stand on its own feet. When capital is accountable, and customers value the service, solutions endure. That’s how clean water becomes infrastructure instead of charity. And how blended finance becomes a tool for real change.

“The single most important challenge in the impact investing space right now is simple: we need more impact investment. More capital, more patient investors, and more venture philanthropy that de-risks good returns for meaningful impact . ”

“What falls apart in the NGO model is the accountability that comes from capital being deployed. Money isn’t a bad thing. It’s a way to measure, and it creates accountability. ”
