What can Terralyn automate?

If you can write a workflow as a list of steps, Terralyn can automate it. Common use cases include:

  • Stakeholder requests: Respond to investor and board inquiries in minutes, not days
  • Data collection and structuring: Turn PDFs, spreadsheets, and raw uploads into clean, analysis-ready outputs
  • Emissions calculations: Scope 1, 2, and 3 tracking with automatic emission factor application
  • Data quality control: Anomaly detection, duplicate removal, schema harmonization
  • Reporting: Generate CSRD, SB-253, and GHG Protocol-ready disclosures

We have templatized automations for utilities data, invoice processing, and supply chain analysis. We can also build custom workflows for your specific needs.

Who is Terralyn built for?

Terralyn is built for enterprise sustainability teams drowning in manual data work. Our typical customers are:

  • Sustainability analysts spending 50%+ of their time on data wrangling
  • Sustainability leaders looking to scale operations without scaling headcount
  • Companies in retail, real estate, manufacturing, and financial services with complex data environments

If your team is stuck formatting spreadsheets instead of driving impact, Terralyn is for you.

What makes Terralyn different from other sustainability platforms?

Traditional sustainability platforms focus on compliance tracking and dashboards, but still require you to clean and format data manually before uploading. Terralyn automates the messy middle: the repetitive, manual work that legacy tools ignore. We're AI-native, not AI-bolted-on. Our platform was built from the ground up to automate sustainability workflows, not just display data.
