Mitchell Possada is on a mission to help hardtech climate founders unlock better capital.
Hardtech climate innovation sits at the heart of the energy transition. From advanced batteries to carbon capture and next-generation manufacturing, these technologies tackle the “atoms problem” of climate change, the physical systems that power our world.
Yet the path to scaling these innovations is rarely straightforward.
Unlike software startups, hardware-heavy climate ventures often face long development timelines, expensive proof-of-concept stages, regulatory hurdles, and large capital requirements before revenue becomes predictable. Many founders focus on raising the next round of equity, but far fewer think deeply about the long-term structure of their capital formation.
For Mitchell, Partner at High Impact Capital Partners, helping founders navigate that complexity has become a mission.
“Hardtech innovation is some of the most interesting and pressing innovation,” he says, “yet it also has one of the hardest paths to success given the long trajectory to a liquidity event.”
After decades working with entrepreneurs, he’s come to believe that the companies that succeed aren’t just good at fundraising, they build their businesses in ways that make them increasingly bankable over time.
The key shift is subtle but powerful: instead of asking how do we raise the next round?, founders should ask how does our capital formation strategy shape the business we are building?
Because in hardtech climate ventures, the structure of capital can determine the speed of scale.
What originally drew you into the world of hardtech and cleantech finance?
Hardtech innovation is some of the most interesting and pressing innovation, yet it has one of the hardest paths to success given the long trajectory to a liquidity event.
There is a lot of satisfaction in helping founders get unblocked and set on an accelerated path to success.
How do you define success, both for yourself and for the founders you support?
I encourage founders to define success themselves by asking a simple question:
What does success look like one year from now, three years from now, and five years from now?
That clarity becomes the foundation for building both the business and the financing strategy.
Why do hardtech climate startups need a different financing trajectory?
Hardtech cleantech businesses are predominantly hardware companies that need to plan their capital formation carefully as they grow.
That means mixing equity funding and debt financing at the right milestones and growth inflection points.
By the time a company reaches Series A, founders should already be thinking about how to accelerate their bankability, because capital stacking will increasingly become necessary.
At the Seed stage, founders may rely heavily on equity and non-dilutive grants. But those resources typically reach their limits early. After that point, building a venture-scale business requires demonstrating that the company can support more sophisticated financing structures.
What do most founders underestimate about financing hardware-based climate ventures?
Many underestimate the complexity of financing hardware ventures.
Capital providers often hold more leverage in these businesses because the risks are higher. Hardware companies frequently face regulatory hurdles, expensive proof-of-concept phases, and uncertainty around manufacturing scale.
In many cases, there is no prior example of the technology being produced at scale, which means investors and lenders must evaluate both engineering and operational risk.
Why do so many early-stage companies struggle to move beyond grants and equity?
Early-stage companies often need to navigate the Technology Readiness Level (TRL) journey just to reach a point where commercialization timelines can be validated.
First-of-a-kind technologies must demonstrate proof points across manufacturing, supply chains, and real-world deployment before capital providers become comfortable funding scale.
Until those milestones are achieved, access to more sophisticated financing remains limited.
What does “accelerating bankability” actually mean?
Accelerating bankability starts with organizational alignment.
Companies need to plan where revenue will come from and ensure that revenue becomes predictable and scalable enough to support financing structures.
This means disciplined execution around cash flow management, billing, and receivables, building the operational credibility required for lenders and investors to trust future projections.
What is capital stacking – and why does it matter?
Capital stacking is a strategy that combines different layers of equity and debt financing, each with different levels of risk and return.
The top of the capital stack is typically the most secure and lowest-risk debt. The bottom of the stack is equity, which carries the highest risk but also the highest upside.
For founders, this structure allows a company to control more of an asset while using less of its own capital, by bringing in different types of investors and lenders at different stages of growth.
But it requires careful planning.
Founders should be able to clearly communicate:
who the next capital partner will be
when they enter the capital stack
and what milestone unlocks their participation
Why does capital efficiency matter so much for hardware startups?
Being capital efficient means not spending before you truly understand what the customer wants you to build.
Founders should align product development, market positioning, and financing with the stage of evolution of the business.
The cost of failing to plan capital effectively isn’t just financial. It can lead to a loss of momentum, missed customer opportunities, and reduced access to future capital.
What happens when founders don’t plan their capital formation early enough?
One common challenge appears when founders try to do too many things at once.
For example, a company might simultaneously try to acquire manufacturing capacity, buy out intellectual property licensing, and launch multiple products at the same time.
That complexity can quickly create confusion around the use of funds, making it harder for investors to understand how capital translates into milestones and value creation.
When that clarity disappears, financing becomes harder and growth slows.
If you had to sum up your philosophy on funding in one sentence?
Have your capital formation strategy drive your business plan and go-to-market strategy.
What’s a mantra you live by?
“Leave a wake of smiles, laughs, and people feeling loved.”
Hardtech climate startups are tackling some of the most complex challenges of the energy transition, and that complexity extends far beyond engineering.
Building the right technology is only half the battle. Designing the right capital structure can be just as critical.
In the next part of this conversation, we move from strategy to execution exploring how founders can shorten sales cycles, use debt intelligently, and communicate their capital strategy clearly to investors and lenders as they scale.
