- 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.
