Common questions
What is the difference between Maiven and Watershed?
Watershed is a sustainability data platform: it ingests emissions data, calculates footprints, and produces reports against frameworks. Maiven is regulatory intelligence: it tracks the policy and regulation that drives what you have to measure and report, and analyses what each change means for your business.
Should I choose Maiven or Watershed?
It depends on the question. For emissions data management and reporting, Watershed. For tracking regulation, understanding what is changing, and getting business-specific impact analysis, Maiven. Most sustainability teams run both.
Does Maiven cover the same regulations Watershed reports against?
Maiven covers the regulations themselves: CSRD, CSDDD, SEC climate rules, ISSB, CBAM, and the wider ESG agenda across 200+ jurisdictions. We track the rule, analyse what it means, and surface the deadlines. Watershed handles the data collection and reporting against those rules.
Can the two work together?
