Profile:

Climate tech strategist at the intersection of technical validation and commercial viability.

After profiling 100+ sustainable aviation startups through interviews, podcasts, and in-depth case studies, I've developed deep pattern recognition for what separates the 10% that reach commercial scale from the 90% that fail, even with promising technology.

My work focuses on the "three valleys of death" in climate tech: the critical funding and operational chasms between lab→pilot, pilot→commercial, and market entry→scale. I help startups navigate these valleys, and help investors identify which companies will actually make it.

Background: Built and scaled two agencies from zero to £3M+ turnover. Now applying that operator experience to climate tech advisory, due diligence, and investment readiness work.Key Skills:

• Sustainability Strategy Development

• Climate Tech Advisory

• Business Scaling

• Content Creation & Thought Leadership

• Project Management

• Marketing & PR

What Sets My Work Apart

1. Operator Experience Meets Technical Depth
I've built businesses from zero to £3M. I understand what founders face because I've faced it. But I also understand the technical side, SAF pathways, hydrogen production routes, battery chemistry trade-offs. This combination is rare.

2. Pattern Recognition at Scale
After 100+ startup profiles, I've seen the patterns. I know which founder mistakes are recoverable and which are fatal. I know which technical approaches have hidden commercial barriers. I know which partnerships accelerate and which distract.

3. The "Three Valleys of Death" Framework
Most people talk about "the valley of death" as a single phenomenon. Through research for Sustainability in the Air: Volume Two, I identified three distinct valleys, each with unique characteristics and survival strategies. This framework helps founders anticipate challenges and helps investors identify which companies can navigate each valley.

4. Honest Assessment
I'm not in the business of selling hope. If a technology has fundamental flaws, I'll say so. If a business model doesn't work at scale, I'll explain why. This honesty makes my positive assessments more valuable, when I say something will work, people trust it.

5. Network Effects
Through the book, podcast, and 100+ published analyses, I've built relationships across the ecosystem: founders, investors, corporates, policymakers. These connections create value for advisory clients through introductions, partnerships, and market intelligence.

Current Focus

For Startups: Investment readiness, strategic positioning, and navigating the three valleys of death

For Investors: Due diligence on climate tech opportunities, deal flow assessment, and pattern recognition consulting
