Persefoni

Persefoni gives a single sustainability owner a concrete free entry point for an organizational inventory, including data arising from event operations. A team needing collaboration, permissions, integrations or detailed exportable reporting should assess the Advanced and add-on quote before treating the free plan as the complete solution.

Honest Limitations

Free Pro is limited to one user

The current FAQ distinguishes single-user Pro from Advanced collaboration and role-based access.

Detailed reports and personal support can cost extra

The free Report Builder is different from paid GHG Metrics Reports and optional Concierge Support. Confirm the exact export required by your reporting process.

Event-level allocation needs design

The product measures organizational emissions. Confirm how shared venues, suppliers and travel records can be attributed to individual events without duplication.

Older users reported learning and import friction

Nicolas Z. described difficulty navigating the interface in March 2023; Sara D. described spreadsheet glitches that support resolved that month. These dated accounts do not describe the current release as a whole.

Pricing Breakdown
Plan Price Details
Persefoni Pro Free Single user, unlimited assets and historical years, Scope 1–3 coverage and the included Sustainability Report Builder.
Persefoni Advanced Quote required Collaboration, governance, integration and more complex organizational reporting requirements.

Hidden Costs to Watch

  • ! Staff time to clean financial/activity records and choose reporting boundaries remains necessary.
  • ! Detailed quantitative exports, extra support and multi-user needs may require paid options.
  • ! Confirm Advanced implementation, contract term, export rights and hosting requirements in the proposal.

Persefoni belongs in an event technology stack when the event operation contributes to an organization-wide carbon inventory. Its free plan provides a defined starting point for one user, but the reporting outputs and collaboration requirements should drive the final plan choice.

For an event team, the most useful pilot is a small set of real venue, travel and procurement records. Confirm how the data is categorized and exported before assuming that a corporate inventory automatically produces a defensible footprint for each event.

The fit assessment follows documented scope. Reviews are dated individual accounts; no hands-on product test or vendor interview is claimed.
