The Best Cleantech Marketing & Sales Partners of 2025
So, the revolutionary solution is all built, real impact, real traction. But somehow, cleantech teams are also expected to be marketing geniuses, sales superstars, and brand architects all at once.
Here’s what most “How to Scale Your Startup” Medium articles don’t mention: doing it all internally isn’t sustainable.
And honestly, it’s not the best use of time.
The right growth partner can accelerate what matters most.
Whether that’s building a sales engine, refining the brand, or generating qualified leads.
Common challenges start to surface websites that no longer reflect the company’s value proposition, messaging that’s out of sync with buyer intent, or investors asking,
“But how do you actually sell this?” All while battling for visibility in search, where algorithms quietly decide whether the company gets seen or sidelined.
To help skip the research lag, we’ve compiled a list of five growth partners trusted by cleantech companies across sales, brand, digital presence, PR, and lead generation.
Each has delivered measurable results in the climate tech space.
1) CleanTech GrowthLab
Superpowers: Paid Media • SEO • Performance Marketing
At Cleantech GrowthLab, we work exclusively with climate companies to build scalable growth engines. Founded by Eben Meyer, we bring cleantech expertise together with 12+ years growth marketing experience driving B2B demand through paid media, SEO, and lead generation.
Our proven playbooks help teams prioritize high-leverage marketing actions at each stage, from generating pipeline to converting it. On average, our clients have seen a 40% lift in qualified conversions within 90 days.
We focus on four core levers:
Reaching high-intent buyers through targeted media and messaging
Building conversion journeys with performance data at the core
Aligning brand and content with what customers actually search for
Equipping teams with sales tools that reduce friction and build trust.
Checkout our Cleantech GTM Canvas, which outlines a step-by-step approach to setting up early marketing and sales motions.
Because we work exclusively in cleantech, we understand the urgency, the stakeholders, and the complexity, so there’s no time lost in explaining the intricacies. We move fast and bring proven strategies to grow faster.
2) Spiral Grain
Superpowers: GTM Strategy • Founder‑Led Sales Support • B2B Positioning
Spiral Grain, led by Blake Newcomer, works directly with founders to turn go-to-market strategy into pipeline. Rather than delivering a static playbook, they embed with early teams to shape positioning, messaging, and sales motions in real-time.
They’re especially effective for startups building founder-led sales functions. Their frameworks help founders identify target segments, articulate value clearly, and convert early traction into repeatable wins.
Also noteworthy: Blake started the Growth Compass Podcast; a useful amplifier for early-stage teams. Featuring interviews with cleantech founders and practical GTM insights, it’s a channel that builds visibility and credibility ahead of fundraising or sales cycles.

5) Orange Bird Agency
Superpowers: PR Strategy • Media Relations • Messaging for Climate Solutions
Orange Bird offers public relations services tailored to cleantech and circular economy companies. Since 2017, they’ve developed strong media relationships across the sustainability ecosystem, helping clients gain visibility with relevant outlets and investors.
Their process includes:
Strategic narrative development aligned with buyer and investor personas
Targeted media outreach based on sector relevance and credibility
Reputation-building through consistent, values-driven messaging
They also provide a structured 9-step PR roadmap, ideal for startups preparing for funding rounds or major product milestones.
Scaling Cleantech with Speed, Strategy, and Certainty
The core solution is built. The need is validated. The next step is scale and that rarely happens in isolation.
Each partner in this list was selected for their track record in cleantech, clarity of execution, and ability to accelerate key areas of growth: demand generation, brand positioning, sales enablement, and market visibility.
In a sector where every hour matters, time spent on fixing conversion flows or refining messaging is time lost from advancing the technology itself.
