Is Growth at All Costs the Right Path for Pro-Planet Startups?

For decades, the venture capital (VC) model has driven some of the world’s most transformative businesses. But for founders building pro-planet solutions, one question looms large:

Can we pursue sustainable, impactful growth on a planet with finite resources?

The answer isn’t a simple yes or no. For some startups, chasing rapid growth makes sense—especially if network effects or virality drive their business models. For others, success hinges on finding patient, aligned capital that supports sustainable scaling.

Let’s break it down.

The Role of Network Effects

Network effects occur when every new user makes your platform more valuable to the next.

Take Airbnb, for example:

• Every new host increases the variety and accessibility of stays for guests.

• Every new guest boosts demand, incentivising more hosts to join.

This creates a positive feedback loop, making the platform increasingly valuable for everyone.

For startups like Airbnb, scaling fast is essential to capturing market share and eliminating competitors. Here, VC funding plays a crucial role, enabling rapid user acquisition and platform dominance.

But not every startup relies on network effects.

Consider a unicorn like Canva. Whether it has 100 users or 10 million, the platform experience remains largely the same for each individual user. Canva’s success doesn’t depend on its user base growing exponentially—it comes from offering a valuable service to its customers, one design at a time.

The Power of Virality

Even without network effects, some startups achieve exponential growth through virality.

Take Calendly:

• Users share scheduling links with others, exposing the platform to new users organically.

• This “invite-as-you-use” model means every customer becomes a marketing channel.

Virality allows startups to scale efficiently, with existing users driving new customer acquisition at little to no cost. For such models, raising VC money to fund initial growth can create compounding returns.

The Bottom Line: Unit Economics

Regardless of your model, unit economics—the cost of acquiring and servicing a customer versus the revenue they generate—are critical.

For businesses with strong unit economics, external funding can accelerate growth. But startups with poor unit economics (spending more to acquire customers than they earn) risk scaling unsustainably, even with ample VC backing.

For pro-planet founders, the question becomes:

What kind of capital aligns with your growth strategy?

Finding the Right Capital Stack

Mission-driven startups often face unique challenges: longer development timelines, heavy upfront costs, and the need for sustained impact. While VC funding plays an important role, especially in deep tech or capital-intensive sectors, it’s not the only option.

Building the right capital stack—combining patient capital, grants, equity funding, and other sources—can better align with a startup’s mission and sustainability goals.

Takeaways for Pro-Planet Founders

If you’re building a startup that drives planet-positive impact:

1. Understand Your Model

   • Does your business thrive on network effects or virality? If yes, scaling with VC funding might make sense.

2. Focus on Aligned Capital

   • Seek investors who share your vision and understand the unique challenges of your sector.

3. Prioritise Sustainable Growth

   • Fundraising is a means to an end, not the goal itself. Secure the right capital, then focus on delivering solutions that make a difference.

Scaling Sustainably

The world needs pro-planet solutions now more than ever. By understanding your growth model and aligning your funding strategy, you can scale both impact and sustainability.

Whether you’re raising your first round or building for the long term, the key is balancing growth with purpose—because the best businesses aren’t just profitable; they’re transformative.
