The Opportunity

Problem

Remote climatetech workers face team misalignments due to ineffective virtual collaboration tools ill-suited for complex carbon tracking models.

Solution

ModelMerge acts as version control for carbon models, allowing remote teams to branch, diff, and merge complex tracking files without conflicts. It highlights misalignments in emissions calcs and suggests merges, reducing review cycles. Teams stay aligned via pull requests tailored for model data.

Target Audience

Remote workers in climatetech teams building carbon tracking models

Differentiator

Intelligent diffing for carbon formulas and datasets, beyond code-focused GitHub
