---------------

Andrew Eil is a climate finance and risk specialist turned full‑time climate tech deal lead who has spent nearly 20 years at the intersection of technology, policy, and capital markets. He previously built and ran a climate risk consulting practice for corporates and financial institutions and co‑founded Climate Finance Advisors, a boutique advisory firm focused on commercializing climate‑friendly technologies and crowding in private capital, including in emerging markets. Over those years he worked across government, development banks, philanthropy, and the private sector, giving him a granular view of why climate technologies fail to scale and how to design around those barriers.

That background makes him unusually strong as a startup evaluator. He approaches climate startups like a risk manager, using scenario analysis to test how a business holds up under different market, policy, supply‑chain, and climate futures rather than relying on high‑level TAM slides. Because he has spent decades cataloging the structural headwinds and tailwinds that determine whether a climate solution can commercialize, he can quickly spot when a deep‑tech or hardware company has real product‑market potential, robust economics, and resilience across multiple go‑to‑market paths—skills he now applies as a hands‑on advisor, angel, and SPV lead for early‑stage climate tech founders.

Why climate deep tech on Play Money?

Andrew focuses almost entirely on hardware and deep tech climate companies that sit between “the science works” and “VCs care.” These are typically late pre‑seed to seed companies where the core tech is de‑risked (often via grants) and there is early product–market fit, but revenue is minimal and institutional VCs still say “come back at $1M ARR.” That gap is exactly where angels can have outsized impact and return, because valuations are still low relative to the potential.

Playbook tip: As an angel, expect these to be real businesses solving hard problems, not hype cycles. You are often funding the first commercial pilots and early deployments that turn “good science” into “bankable company.”

Q&A: Who is Andrew and what’s his edge?

Q: Andrew says he’s “new” to angel leadership. Should that worry me?
A: Andrew has only been leading deals for about a year, but he has ~20 years in climate finance, technology, policy, and risk, plus hands‑on work in commercializing climate tech globally (including in emerging markets). What looks like “gut” is actually decades of pattern recognition around what fails and what survives in climate markets.

Q: What exactly does he do for founders and investors?
A: He scouts startups from elite climate/deep‑tech incubators, accelerators, conferences, and networks, runs his own founder AMAs, and does deep, question‑driven diligence before ever bringing a deal to investors. With selected founders, he works almost like a fractional team member: helping map capital sources (grants, angels, SPVs, corporate, non‑dilutive), refine go‑to‑market, and navigate risk and commercialization barriers.

Playbook tip: Treat “Andrew is leading” as a strong prior that (a) the founder has cleared a high bar and (b) there is a serious, long‑term partner in the trenches with them, not just a check‑writer.

What stage and profile of startup does Andrew like?

Stage sweet spot

Late pre‑seed / seed. Product and core tech are de‑risked; often early pilots or strong proof of concept.
Often pre‑revenue or early revenue, but with a credible, near‑term commercial path.

Founder profile

Technical founders who know their market “in their bones,” often older and battle‑scarred rather than fresh out of big‑name tech.
Founders who have taken “lumps” trying to commercialize, not just building in the lab; they understand workflows, users, and how value is actually created.

Playbook tip: When you see an Andrew‑backed deal, expect gritty, technical founders with real domain depth rather than polished “beauty contest” pedigrees.

What does Andrew screen out?

Andrew passes quickly on:

Companies dependent on government subsidy, regulation, or procurement to make the business work.
Models where profitability lives inside a narrow band of commodity or market prices (e.g., works only if input prices stay within ±20%).
Hyper‑crowded, fast‑copycat software/AI categories where defensibility is unclear and customers struggle to see meaningful differentiation.
Extremely capex‑intensive sectors (fusion, large nuclear, certain hydrogen plays) that require tens/hundreds of millions and fragile policy support.

Playbook tip: If a company “only works if XYZ policy happens” or “only works if commodity prices stay here,” assume Andrew is not touching it. When he is in a deal, he believes it survives multiple macro and market scenarios.

How does Andrew think about risk?

Scenario analysis, not TAM slides

Andrew is skeptical of TAM as a core decision metric, especially for “blue sky” markets that don’t exist yet. Instead, he runs structured “what if” scenarios: different political regimes, supply‑chain shocks, climate impacts, technology cost curves, and customer behavior shifts to see if the business can stay resilient.

Playbook tip: When evaluating an Andrew deal, ask yourself: “If this market develops slower, regulations change, or input costs swing, does this business still have ways to win?” That is exactly how he is thinking.

Structural headwinds and tailwinds

He looks for:

Acute, intensifying problems (e.g., wildfire risk, water stress, insurance issues) that must be solved, not “nice to have” ESG upgrades.
Markets where climate and economic forces guarantee demand growth, even if timing is uncertain (e.g., resilience, risk analytics, low‑cost circular inputs).

Playbook tip: If customers would buy this even if they didn’t care about climate at all, purely for cost, risk, or operational reasons, that’s a strong positive signal.

What kind of business models and tech does he favor?

Radical cost advantage, not “green premium”

Andrew wants technologies that are so cost‑advantaged they can undercut incumbents (including “brown/gray” competitors), not just match them with a green story. He loves models using waste feedstocks (sometimes with negative input costs) and novel processes that make production radically cheaper and modular.

Playbook tip: In his world, “no green premium” is table stakes; the dream is “green and much cheaper.” Look for language about order‑of‑magnitude savings, negative cost inputs, or structurally higher margins than incumbents.

Platform, modular, multi‑market tech

He intentionally seeks technologies that:

Can be deployed at different scales (small to large) because they are modular.
Have multiple plausible verticals; the company can pick low‑friction early markets and pivot if the first one struggles.

Some investors fear “too many possible markets = lack of focus.” Andrew views optionality as a key resilience feature, so long as the founders have a clear current go‑to‑market plan.

Playbook tip: Don’t confuse “platform” with “unfocused.” Ask: Do they have a sharp initial GTM and believable backup markets if they need to pivot? That’s exactly the balance Andrew prizes.

How does he think about government, grants, and non‑dilutive capital?

Many of Andrew’s companies have been heavily de‑risked with grants and public funding before angels see them. He sees this as a feature: angels are stepping in after the hardest science risk is removed, to fund commercialization, pilots, and early scale‑up.

At the same time, he avoids companies whose ongoing business model depends on government checks or fragile policy regimes. He also helps founders mine non‑dilutive sources (SBIR, ARPA‑E, DOD programs, philanthropy, state/local schemes, prizes) to stretch equity capital.

Playbook tip: When you see “millions in prior grant funding” plus “now raising seed,” translate that as: “Taxpayers paid for a lot of the science risk; angels can now fund the commercial unlock at relatively low entry valuations.”

How big is the funding gap and what are angels filling?

For the kinds of climate deep‑tech companies Andrew backs, the critical gap is usually low single‑digit millions: enough to build and operate a few commercial pilots or fulfill key early contracts to become credibly “bankable.” Institutional VCs are increasingly demanding Series A–level revenue and traction in what used to be seed rounds, which many deep tech founders simply cannot reach without that interim capital.

Playbook tip: Think of your check (and the SPV) as buying the company the right to prove itself in the field—funding the first real deployments that unlock later VC and project finance.

How does Andrew work with founders on capital strategy?

Many founders show up saying, “We’ve been trying to raise a $2M seed with a lead for nine months and getting nowhere.” Andrew often:

Re‑examines how much they truly need now versus later and whether equity is the right tool.
Redirects fundraising away from traditional VC to a mix of angels, SPVs, crowdfunding, grants, prize competitions, corporate pilots, and other lower‑friction capital.

He looks for “resource magnetism”: founders who can find creative ways to bring in money and non‑cash support, but also recognizes that most don’t know the full menu of options across philanthropy, government, corporates, and impact capital.

Playbook tip: When Andrew leads an SPV on Play Money, you’re usually part of a carefully constructed capital stack designed to get the company to its next truly meaningful de‑risking milestone, not just “more runway.”

How does Andrew think about product–market fit and commercialization?

Beyond the lab

He is wary of deep‑tech teams that stay in the lab for years aiming for perfection before customer exposure. He wants to see some version of rapid prototyping and early market feedback, adapted from software best practices to hardware constraints.

Playbook tip: Look for signs that the company has already put imperfect versions of the product in front of real customers, learned, and iterated, even if the tech is complex.

“Hair‑on‑fire” problems

Andrew looks for customers with urgent, job‑threatening problems, not “nice‑to‑haves.” In his experience, many sustainability products fail because nobody in the C‑suite loses sleep (or their job) if they don’t buy them.

Playbook tip: When reading a memo, ask: Who is losing sleep over this problem? If there isn’t a clearly desperate buyer persona, Andrew probably wouldn’t be leading the deal.

Why does he love companies like Mothership Materials

Without sharing confidential details, Andrew has a few “highest conviction” companies that illustrate his thesis:

Companies like Mothership that, once proven, can generate eye‑popping margins because they fundamentally change cost and performance economics in their category.
Companies like Athena Intelligence in wildfire risk, where better tools could prevent catastrophic, multi‑billion‑dollar losses by telling society exactly what to do, where, and when—yet today’s customers barely know how to tell a good tool from a bad one.

He is especially drawn to “underdogs”: founders without flashy pedigrees, in hard‑to‑sell markets (insurance, utilities, government), who nevertheless have demonstrably better technology and are finally on the cusp of a breakout.

Playbook tip: Expect Andrew deals to feel a bit “under the radar”—less polished, more substance. The upside is that valuations are still sane while the technology edge is very real.

How does he think about portfolio construction and returns?

Andrew invests at valuations that are often in the single‑digit to low‑double‑digit millions for companies he believes can credibly become hundreds‑of‑millions to billion‑dollar businesses. He’s explicit that the math works even if only a fraction of the portfolio is a big win, due to the multiple on low entry prices.

Playbook tip: As an angel alongside him, the game is not to predict perfection in every company, but to (a) trust the bar he sets, (b) build a portfolio across several of his deals, and (c) let the math of low‑entry‑high‑upside work over time.

How seriously does Andrew take trust and curation?

Reputation is everything in his model. He is extremely reluctant to promote companies he hasn’t diligenced or that sit outside his lane; when he does share something outside his conviction, he labels it clearly as “not diligenced.” Bringing a company to his network is effectively giving it an “Andrew stamp of approval,” a privilege he guards carefully.

Playbook tip: When you see “Andrew is leading this SPV” on Play Money, treat that as a meaningful filter. He is acutely aware that one bad or lazy recommendation can destroy trust he has spent years building with both founders and investors.

What does this mean for Play Money angels?

You are being shown a very small, highly filtered slice of climate deep tech that has already passed a demanding risk, resilience, and commercialization screen.
The “information gap” is about how to think like Andrew, not whether the deal is worth looking at; this playbook is meant to close that gap so more of you can invest with confidence.
Over time, the shared goal is that when an “Andrew deal” hits the platform, enough of you understand his framework that high‑quality climate companies can reliably raise the low‑single‑digit millions they need to break out.

Playbook tip: If you care about climate and returns, and you resonate with this framework, consider anchoring part of your Play Money portfolio in Andrew‑led deals and learning his pattern‑recognition over time. The edge here is not just the companies; it’s the way he selects and supports them
