Climate Tech Early Customer Acquisition: How Founders Get First Deals

01

Scott Graybeal

CEO of Caelux

Lesson 01 of 09

Sell to the End Buyer to Create Demand on the Supply Side

Scott Graybeal built Caelux’s early customer acquisition strategy around the buyers who fund projects rather than the manufacturers who would integrate the product.

The logic was explicit: if the people writing the checks are asking for your technology by name, the supply side faces pressure to move regardless of their own timeline. “We work a lot with the downstream players in the market, meaning the asset owners and developers that will be the biggest beneficiaries of the technology that we’re bringing to the market. And so getting them excited, having these early demonstration projects is absolutely key to our marketing strategy.” The goal was to build a history with those buyers before the product was fully adopted upstream: “We want them to spec us in for the next project.

So even if module companies, if they may be a little slow to adopt, we want to ensure that the folks that are writing the checks understand what’s available and have a history of working with them.”

Kathy Hannun

Founder and CTO of Dandelion

Lesson 02 of 09

Borrow the Financing Infrastructure From an Adjacent Industry

When Kathy Hannun identified that upfront cost was blocking conversion, she looked to the solar industry for a solution rather than building one from scratch.

“The simple idea of applying financing to geothermal, which seems very intuitive. It’s just copying what solar did and bringing it to geo. But it really wasn’t being done at that time.” She then went directly to the solar finance companies that already existed and pitched them to expand their products to a new category.

“We were able to pitch, why don’t you expand it to geothermal? And it was very hard actually. Everyone said no.

Except for EnerBank was the only company that said yes, but you only need one.” That single yes unlocked a zero-down purchase option that transformed who could buy. “It allowed us to offer a zero money down product which was also used by half of our customers. I think maybe a little bit more than half in the beginning.

So you’re doubling the market with financing.”

CEO & Co-Founder of Modo Energy

Lesson 03 of 09

Name Your First Target Customers Before You Define Your ICP

Quentin skipped abstract ICP frameworks in the early days and got specific: “We originally built the service with an ICP with 20 names on it.

So we wrote down the actual names and put them on the wall of the people that we wanted to.” The approach came directly from Geoffrey Moore’s beachhead logic: “It was after reading the Crossing the Chasm book about having a really small beachhead and expanding from there.” That level of specificity also created an unexpected sales signal. “It was such a small market at the time that these folks could not believe that we were building software for them. Somebody is building software for just 20 of us.” Being built for a tiny, named audience turned out to be a feature.

Early customer acquisition gets easier when your list is small enough to be personal. A prospect who feels like one of twenty is far easier to convert.

Allison Wolff

CEO of Vibrant Planet

Lesson 04 of 09

Get a Working Product Into a High-Stakes Environment Before You Sell

Allison Wolff’s approach to early customer acquisition started with a conviction she traced directly to her Silicon Valley career: “One of the things I learned working in Silicon Valley for my whole career was you have to show people what’s possible.” Rather than pitching a concept, Vibrant Planet invested in getting a functioning MVP deployed in a credible, high-risk context that target customers could see and react to.

From there, the sales process became a co-design process: “We really co-designed the system with them as they were going through a risk management workflow. We built it side by side with them, and then they became our earliest and biggest paying customers once they saw the potential of the system to help do what they needed to do.” Giving prospects something real to engage with, rather than a demo or a deck, was what converted early interest into first revenue.

Manik Suri

CEO and Founder of GlacierGrid (exTherma)

Lesson 05 of 09

Prove Measurable Value Before Asking Prospects to Commit

Manik was direct about what it takes to close early customers with no brand, no track record, and a lean budget: “when you’re selling to businesses, you’ve got to demonstrate some type of value that’s measurable if you really want to get people to put dollars behind it and invest, and especially when you have no reputation and limited product in kind of a small marketing budget.

I think it’s really about staying close to the customer’s pain and being able to show that you’re solving some problem for them in a value creating way.” When the company tested its new product with existing customers, that principle showed up in the results: “what we were able to do early on was work with existing co-inspect customers, test our new product with them, and what we saw was a lot more pull than push. The adoption was way faster than anything we’d seen with the first product we launched.” Measurable value, demonstrated early, is what converted skeptical prospects into committed buyers.

Dr. Kai Philipp Kairies

CEO and Co-Founder of ACCURE

Lesson 06 of 09

Convert Industry Relationships Into Your First Paying Customers

Before ACCURE had a sales team or a marketing function, Kai had nearly a decade of relationships with the people his company needed to sell to.

As he described it, “the first contracts that we got, the first one, and then also the next three or four ones, they all came from my network. So it was people that I had a relationship with that trusted me, and that most of them had worked in other situations with me or my team before. So they knew that we were solid, they knew that we could deliver.” The pitch wasn’t a cold value proposition.

It was a conversation built on shared history: “we said, hey, with all the information that we got to know you in the last time, this is something we believe could be really good for you. And they said, yes.” Founders with deep domain experience should treat their professional network as their first and most valuable sales channel before building anything else.

Founder and CEO of Beebop.ai

Lesson 07 of 09

Build Domain Credibility Before You Need to Sell

When Jan-Willem launched Beebop, he didn’t start from zero.

The team’s prior work in the market meant that early conversations with large utilities started from a foundation of trust rather than skepticism. “We had a track record as pioneers in this market” and “were able to step in to a few large suppliers, utilities, and get their trust to help them build their virtual power plant.” That credibility translated directly into revenue before the platform was complete: “we had customers almost from the start of just right when we started, the companies that we’re super grateful to that trusted our team and paid us to set up this virtual power plant and where we helped them set it up while we were building the platform.” The lesson is that domain reputation, built before a company exists, can compress the early sales cycle in ways that no cold outreach strategy can replicate.

Gary Ong

CEO and Founder of Celadyne Technologies

Lesson 08 of 09

Enter Emerging Markets Early to Build Relationships Before You Need Them

Gary Ong’s ability to reach major enterprise buyers without a formal sales function came directly from how early he entered his market.

“Back in 2018, when no one was doing hydrogen, if you were in the hydrogen space, you kind of knew everyone, so it wasn’t that hard to get to even the Toyotas of the world.” When it came time to acquire customers, those relationships were already in place. “The way we’ve approached it is we used a lot of our connections that were available to us through the hydrogen ecosystem already.” The result was a sales motion built entirely on proximity to buyers: “In my business, marketing looks a lot more kind of high touch B2B, marketing, where you literally know the purchasing decision makers and so on and so forth, and they know you rather than a scattershot approach where you do social media and stuff like that.” Founders who move early into an emerging space accumulate relationship capital that becomes a structural advantage when the market matures.

Lesson 09 of 09

Serve Early Customers for Free to Accelerate Early Customer Learning

When Greenly moved into corporate carbon accounting, Alexis started by working with small companies at no cost.

“We started working with SMBs, with very small companies, tech companies like trying it out, doing it for free.” The goal was market understanding, not revenue. That period of free work gave the team enough signal to see the opportunity clearly: “But we start to get it and we understand there’s a market and if the price is low enough, you’re kind of disrupting this consultancy led business by broadening the base of companies that would want to do this.” Removing price as a barrier early accelerates learning and gets real customers using the product before you’ve committed to a model. When price is no longer the obstacle, you find out quickly whether the real obstacles are the product, the workflow, or the buyer’s willingness to change how they work at all.
