💎 If you've invested in Aquaria, Mothership Materials, Carbon Bridge, or Tikal Industries (the sexy cement co), you know Andrew Eil. 

We all win when people like Andrew get to do what they’re best at: using deep domain expertise to spot and accelerate the most important innovations on the planet.

My 30 minute call with Andrew lasted nearly 2 hours. I left convinced I want to invest in every deal he brings to Play Money. Enjoy!

Everyone Wants Climate Wins. Almost No One Knows How to Pick Them.

Most VCs say they invest “early.” Almost none of them are willing to fund the moment that actually matters for climate deep tech: the messy, expensive leap from lab to first real customers.

That’s the gap Andrew Eil lives in.

Andrew has spent nearly 20 years in climate finance, technology, policy, and risk. He’s worked with governments, development banks, corporates, and founders to answer one hard question: Which climate technologies actually have a shot at becoming big, durable businesses? 

Today, he’s turned that playbook into sourcing and leading some of the highest‑conviction climate deals on Play Money.

And the way he evaluates companies is very different from most investors you’ve met.

Aquaria is one of the most talked-about climate resilience companies of the year. And it's no surprise: they've grown from $490K to $24M+ in revenue in under 18 months by turning air into drinking water.

Aquaria has been extended to 12/12 due to high interest.

Why Angels Should Care About “Andrew Deals”

Here’s how Andrew describes the companies he loves:

Deep tech and hardware, not hype. The science is de‑risked (thanks to millions in grants), and now the real challenge is commercialization, not “can the physics work.”

No government crutches. If a business model only works with subsidies, procurement, or fragile policy support, he passes. Climate may be the mission, but the customer must buy for hard‑nosed cost, risk, or operational reasons.

Radically better economics. He wants tech that can be 50% cheaper than existing solutions, or an order of magnitude better—often by using waste feedstocks, modular production, and novel processes. No green premium. Green and cheaper.

“Hair‑on‑fire” problems. If no one in the C‑suite is losing sleep or their job over the problem, he’s not betting his time or capital on it.

He also looks for something most investors misread:

Founders with “too many” potential markets.

Where others see lack of focus, Andrew sees resilience. If the tech can win in multiple verticals, the company has life rafts when the first go‑to‑market doesn’t pan out. The key is a clear first beachhead plus believable backup plans—not a single, brittle bet.

How He De‑Risks Startups (and Why Founders Fight to Work With Him)

Andrew isn’t a traditional “fundraiser" or fund manager. He’s effectively a fractional risk officer and commercialization strategist embedded with early‑stage teams.

The kinds of things he does with founders:

Designs the capital stack, not just “the round.” Instead of “raise a $2M seed with a lead,” he helps right‑size the cash needed to hit real de‑risking milestones (pilots, first contracts, bankability) and then matches that with the right instruments: angels, SPVs, grants, prizes, corporate pilots, and more.

Runs scenario analysis like a risk manager. He asks: What if policy flips? What if input prices swing 20%? What if supply chains get hit? Does the business still stand? If the answer is “only if everything goes perfectly,” he walks.

Pushes tech out of the lab. He borrows the best of software—rapid prototyping and early user feedback—and forces deep‑tech teams to test whether customers truly understand, use, and value the product before they burn years perfecting it in isolation.

Founders who clear that bar don’t just get an angel. They get a zealous advocate who will bulldoze a path through capital markets and early customers with them.

Why Play Money is Leaning in

On Play Money, you’ve already seen Andrew’s fingerprints on deals like Aquaria, Mothership Materials, Carbon Bridge, and Tikal (cement is sexy!).

Over the next few months, you’ll see more “Andrew deals” on the platform—and more behind‑the‑scenes education on how he thinks, so you can evaluate these opportunities with the same lens instead of sitting on the sidelines because they feel “too technical.”

If you care about climate and believe in backing real companies with real moats this is where things get interesting.
