Your case is different. But not that different.

I advise, build and write at the intersection of technology, human systems and environmental risk, bridging the technical and commercial sides of organisations. 25 years of failures, misunderstandings and disappointments, put to work.

Who I work with:

  • Startups turning a good idea into an organisation that delivers
  • Scaleups where what worked at 8 people breaks at 20
  • Consultancies moving from selling hours to selling a product
  • Enterprises who need reliable environmental data and service providers
  • Investors who need to look past the pitch deck

Questions I help answer:

  • What do we build next, and what do we refuse to build?
  • Who do we hire, and when do we need real management?
  • What is our product, and what stays consultancy?
  • How do we connect landscape risk to our supply chain?
  • Is this company’s tech what they claim it is?

I build products to show how I think, not just say it. I write about it in near real time so you can follow along, steal my ideas.

Go To Market strategy, and its discontents

When I started working, I didn’t know what a Go To Market (GTM) strategy was. When I joined a company as a co-founder, 15 years later, I still had never heard of a GTM. Now, another decade along, I still only have a vague idea of what it actually means. So I wrote an essay on what GTM is, how it relates to the Consultancy 2 Saas maturity model and how you can recognise common mistakes. The essay is written from the lens of “a new product in a new market”: growing companies in the environmental supply chain risk sector. It doesn’t take much imagination to apply the model to other sectors as well. ...
