By facilitating collaborative identification of problems that connect researchers to funding we're accelerating research in climate biotech.

Homeworld Collective @homeworld.bsky.social · 29/07/2025

This marks the execution of our first true Roadmap-Ignite-Fund-Synthesize (RIFS) cycle and the results exceeded our expectations. Our funding hypothesis was simple: surfacing important problems would be mutually reinforcing to funding solutions.

Garden Grants addresses both issues by spotlighting the most urgent challenges and supporting the bold approaches researchers propose to solve them.

Homeworld Collective @homeworld.bsky.social · 11/04/2025

Why share problems openly? Homeworld identified two critical gaps in the climate biotech space: risk-tolerant funding and limited interaction and collaboration among teams.

Homeworld Collective @homeworld.bsky.social · 11/04/2025

By sharing the problems transparently (while keeping proposed solutions confidential), we aim to foster cross-pollination of ideas, stimulate community discourse, and attract philanthropic funding into climate biotech.

◾️Want to help shape this? We’re deciding whether to extend this AI-based TEA tool more generally. If you think a low-cost, AI-driven TEA can speed up your biotech journey, please let us know. Your feedback will guide us on whether to invest more resources into making this tool widely accessible.

Homeworld Collective @homeworld.bsky.social · 07/03/2025

◾️Where are we now? We’ve wrapped up our prototype stage (read the report in our latest blog post) and are shifting our focus to biomining. Jesse and Jayme are spearheading a new TEA product specifically for biomining, and we’ll roll out a usable version soon.

Homeworld Collective @homeworld.bsky.social · 07/03/2025

At Homeworld, we have been prototyping an AI-driven TEA tool in order to help biotechnologists map their ideas to deployments. ◾️Why use AI? Currently, it costs $5k-$10k to even get a basic model started, but AI can deliver a solid starting point for a fraction of that.

pMMO naturally destroys methane, making it a potentially powerful tool for methane mitigation. But pMMO’s sensitivity to its membrane environment, as well as a lack of tools for manipulating and measuring its activity, make it hard to engineer. Key challenges include:
