In recent years, the rise of climate and impact startups has been inspiring. Founders are building solutions to some of the world’s most pressing challenges, from renewable energy innovations to social entrepreneurship. Yet, despite the urgency of these missions, many of these startups struggle to survive.
After speaking with several founders who had to shut down their ventures, a common theme emerged: no product-market fit.
While passion and purpose are essential, they can’t replace the need for a product that the market actually wants. A CB Insights report shows that 35% of startups fail due to lack of market need, making it the most common reason for startup failure. This issue is even more pressing in the climate and impact sector, where aligning solutions with real-world demand can be challenging.
What is Product-Market Fit?
Most founders understand the importance of product-market fit (PMF), but achieving it in the climate and impact space requires additional nuance. Climate startups face not only the challenge of product development but also the responsibility of addressing systemic environmental or social issues.
In our conversations with climate founders, we often hear that while the mission is clear, the market need isn’t well defined. As Marc Andreessen, one of Silicon Valley’s top investors, puts it: “Product-market fit means being in a good market with a product that can satisfy that market.”
Without it, even the best-designed solutions will struggle to gain traction.
Three Key Stages of Achieving Product-Market Fit for Climate and Impact Startups
Here are three key stages that can help climate and impact startups achieve product-market fit:
- Hypothesis Testing
- Market Validation
- Scaling with Focus
1. Hypothesis Testing: What Problem Are You Solving?
Before committing resources to any solution, founders should begin by hypothesizing what problem they are trying to solve and for whom. This is especially important for climate and impact startups, where solutions often address complex, systemic issues like carbon reduction, biodiversity loss, or social inequality.
Example Hypotheses for Climate Startups:
- “Consumers are willing to pay a premium for biodegradable packaging if it reduces environmental harm.”
- “Municipal governments will invest in carbon offset technology to meet sustainability goals.”
At this stage, founders should focus on problem discovery rather than building an entire product. Tools like design thinking and lean startup methodologies can help structure this process:
- Customer Interviews: Direct conversations with potential customers in different niches (e.g., governments, non-profits, sustainability-conscious consumers) can help validate whether the problem is significant enough for people to pay for a solution.
- Problem-Solution Fit: Do customers feel the pain point as urgently as you do? Would they adopt your product if it existed today? If so, under what conditions?
Framework Tip: Use Lean Canvas to outline the problem, potential solution, key metrics, and customer segments. This keeps your focus sharp as you iterate on your initial hypothesis.
2. Market Validation: Test Across Multiple Niches
Once you have identified a problem worth solving, the next step is to validate your product by testing in different customer segments. For climate and impact startups, there’s an even greater need to target different stakeholders—each with different incentives and purchasing criteria. These might include:
- Governments looking to meet sustainability targets.
- Businesses searching for ESG-compliant solutions.
- Consumers prioritising sustainable living.
Instead of going all-in on one solution for one audience, consider using the “bowling pin strategy.” This approach focuses on winning over a single niche before expanding to other customer segments, like knocking down one bowling pin that leads to knocking down others.
Example: Oatly's founder shared in their interview with us that, initially focused on families dealing with milk protein allergies—a small but underserved niche. After gaining traction with this group, they expanded into the coffee market, where their oat milk became a favorite due to its superior texture compared to other plant-based milks.
Tactical Steps to Validate Your Product in Different Niches:
- Micro-Market Testing: Set up small pilots across different customer groups. For example:
- Test a renewable energy solution with urban municipalities versus rural communities.
- Offer a limited run of sustainable consumer products and track which demographic responds most positively.
- Use Minimal Viable Products (MVPs): Build simple, functional versions of your product to validate core assumptions. For instance, an MVP for a carbon offset project might include a basic online platform and partnerships with companies looking to buy offsets.
- Track Key Metrics: As you test in multiple segments, monitor early signals of traction:
- Conversion Rates: What percentage of interested customers are converting into paying users?
- Retention Rates: Are early adopters sticking with your product over time?
- Referrals: Are your users recommending your solution to others?
Framework Tip: Create a Customer Acquisition Funnel for each niche you’re testing. This allows you to assess which group responds best and where your resources should be focused.
3. Scaling with Focus: Double Down on the Most Promising Niche
Once your MVP has gained traction, and one or more customer segments show strong signs of adoption, it’s time to double down. Rather than attempting to serve every niche at once, scale within the most promising market segment.
Scaling Insights from Oatly: After success in the coffee market, Oatly expanded into mass retail, but they did so strategically. They focused on markets (like health-conscious millennials) that aligned with their initial product values.
What This Means for Climate Startups:
- Focus on Vertical Growth: If your carbon offset solution is gaining traction with local governments, grow within that segment by expanding into additional municipalities.
- Avoid Horizontal Growth Too Early: Don’t jump to other products or services until your core product is thriving in its target market.
Framework Tip: Use the OKR (Objectives and Key Results) framework to ensure your scaling efforts remain aligned with your overall mission. Focus on clear, measurable outcomes for growth.
Customer Personas: The Key to Understanding Your Market
To effectively explore different niches, founders need a deep understanding of their potential customers. This is where customer personas come in. A detailed profile of your ideal customer, customer personas help better align product development, marketing, and sales strategies.
In the climate and impact space, your customers might be local governments, NGOs, or sustainability-conscious consumers, each with different needs and challenges.
Research shows that companies using customer personas generate 5 times more revenue than those that don’t. For more on this, check out our post on Mastering Customer Personas (link in comments).
What About Marketing and Brand Building?
One mistake many founders make is focusing too much on marketing and brand building before validating their product. While having a strong brand is important, it should come after you’ve confirmed product-market fit.
As Paul Graham, founder of Y Combinator, famously said:
“It’s better to have 100 users that love you than a million users who kinda like you.”
