Get in touchWhen you need more capacity and pace than the volunteer model can give, CML steps up on a fully commercial basis, like a dedicated agency, with the same people, method and climate focus you already trust.
- Greater capacity, faster delivery
- The same team that knows your story
- Half of our net profit funds the next climate venture
Can’t afford £200/month? You may qualify for sponsored support, funded by corporate partners who back early-stage climate ventures: same method, same senior volunteers, delivered as part of a sponsored cohort.
Need more than the £200/month Pro level? We become your agency.
As you grow, you may need more capacity and pace than our volunteer model can give. When that point comes, CML can work with you on a fully commercial basis, like a dedicated sales and marketing agency, with the same people, method and climate focus you already trust.
It is a natural next step, not a different supplier: the team that knows your story simply scales up to deliver more, faster.
Hire us, and half of our net profit funds the next climate venture.
Every penny you spend on commercial work does double duty: half of CML’s net profit goes towards supporting other climate and sustainability ventures, the startups and NGOs that can’t yet afford help. You get agency-grade delivery, safe in the knowledge your spend keeps accelerating the wider mission.
How Half for Profit worksFrom first call to live, in five clear steps
A 45-minute Teams call
Two or three calls as needed. We dig into your specific sales and marketing challenges and explore whether this partnership will be valuable.
Plan review
Together we build a business-development plan. It is yours to use entirely on your own, free of charge, or you can implement it with CML and our volunteer network.
Volunteer SLA & invoice
You review and sign our Volunteer SLA covering roles, expectations and confidentiality. We invoice for the first three months, with no commitment beyond.
Onboarded & live
Your volunteer team gets to work, prioritising the plan with bi-weekly check-ins and the flexibility to adjust scope as your needs evolve.
Three-month review
Did we achieve what we set out to? We review the impact together and decide what you want to do next.
Entirely confidential
Everything we discuss and produce is treated in strict confidence. Our Volunteer SLA sets out clear expectations on confidentiality and conduct, so you can share openly and move quickly.
Flexible by design
Scope flexes with your priorities. Scale support up as you grow, or step back at the end of any three-month cycle. The plan is always yours.
A proven path, from understanding your business to closing the sale
Every engagement follows the same disciplined sequence, adapted to your stage and sector.
