- Third Sphere

I really enjoy your monthly newsletters and read them (and various links therein) with interest.  I would actually go so far as to say that your newsletter is the most interesting of all VC letters that I read, probably largely because it is focussed around solving the largest problem in history.

I love these newsletters, I think the Third Sphere programme produces some of the most interesting startups in the climate sector. I often refer to the start-ups in report recommendations.

I learn more about what’s happening in the climate tech scene through Third Sphere’ newsletter than any source out there!

Just a note to say how much I love these. They cut through the newsletter noise really effectively and I usually learn something. Keep ‘em coming!

Just want to say I love these updates and you pull together some really important links that I don’t otherwise come across.

Will keep following with interest.

Amazing community, looking forward to continuing to build connections w/ a number of folks.

Once a month we produce our email updates covering new investments, insights and opportunities at the intersection of startups, cities and climate change. There is no time to waste, so we mark the weeks since we started and begin each subject with the current week.
