"It wasn't selling I believed in running." Phil Knight founder of Nike
We like you, believe in what we are doing, we're not selling a service because we want to sell (don't get us wrong we love doing it) but because we, like you, want to make an impact. Our impact is making your impact bigger, much bigger. If you are a climate, climate-tech or sustainability startup or scale-up, we help you sharpen your story, find your customers, and build a pipeline that helps fund your mission.
Three tiers, one method
"Product and sales first, everything else after" Bloomberg built the product first, but selling was the only process he ran at the same time as development from day one. You can't start selling too soon - begin with our quick, low-commitment, no cost way to get expert eyes on your sales strategy, then scale support to match your ambition and budget, all the way up to a Fractional Head of Sales.
A quick, low-commitment, no cost way to get expert eyes on your sales strategy, working with our most experienced and senior volunteers. Two to three short calls plus analysis over 1–2 weeks, delivered as a clear one-page “story + numbers.” Act on it yourself, or implement later with us. Investors love their start ups to have an expert verified sales plan. We will build you a Customer Value Proposition you can use to help drive your business.

Keen to take that next step and start the scale up, but budget is a big constraint. Talk to us about our funded options, we'll already be working together on one of the programmes above and ideally have already seen some sales. In which case we can potentially find small scale investment to start scaling sales on a case by case basis. NB: Please don't approach us cold, we can only offer this to qualifying existing clients. Separately - NGOs & unfunded start ups can be supported by our corporate clients.

How Half for Profit worksFrom first call to live, in five clear steps
Strategy Sprint - Teams call(s) & Delivery
With our experienced senior exec volunteers - two or three calls as needed. We dig into your specific sales and marketing challenges and explore whether this partnership will be valuable. Together we build your customer value proposition and business-development plan. It is yours to use entirely on your own, at no cost, or you can implement it with CML and our volunteer network.
Managed support - Volunteer setup
If you want to develop some of those ideas and implement them. You review and sign our Volunteer SLA covering roles, expectations and confidentiality. We invoice for the first three months, with no commitment beyond. We assign you volunteers keen to help you get your work done, guided by our senior team.
Managed support - Onboarded & live
Your volunteer team gets to work, prioritising the plan with weekly check-ins and the flexibility to adjust scope as your needs evolve. Our senior team are still available for discussion if need.
Managed support - Three-month review
Did we achieve what we set out to? We review the impact together and decide what you want to do next. You can finish here and always come back to us later, continue with the managed support for a further 3 months, or move up to our Fractional Head of Sales model
