What they've been talking about across their social media accounts

- Dedicated focus on finding novel hardware and software solutions for climate change while ensuring these innovations reach beyond wealthy urban populations. Specific examples of this interest include tracking unexpected sustainability trends like the rise of non-psychedelic mushroom startups and exploring bioluminescence as a viable alternative to traditional lighting.
- Hands-on enthusiasm for coding and leveraging artificial intelligence to build practical tools and streamline workflows. A great example of this is a weekend project using Python and artificial intelligence assistance to build an event check-in application, as well as writing a script to automate buying hundreds of audiobooks for the climate tech community. There is also a strong desire to see these generative artificial intelligence tools applied directly to solving climate challenges.
- Deep curiosity about the behavioral economics and psychological hurdles consumers face when transitioning to green technology. A relevant example is analyzing the deep cultural attachment people have to gas stoves and wondering if electric stoves might need digital flames to boost adoption, comparing it to how some electric vehicles use artificial engine sounds to comfort drivers.

Third Sphere is an early-stage climate fund that concentrates 80% of its portfolio in hardware-enabled solutions while most VCs avoid hardware, building specialized playbooks for funding physical systems and pioneering climate resilience beyond just carbon reduction. The firm operationalizes a "Seedstrapping" model that combines $250k-$1m investments with AI-driven efficiency and alternative financing to help hardware companies reach $1m ARR or $10m in pre-orders within six months, making traditional growth VC optional.
