Persefoni Pro
Carbon accounting is complex and time-intensive. If you're not a sustainability professional, you likely don't even know where to begin.
Many organizations either need to (due to regulation) or want to (for values or stakeholder pressure) calculate their carbon footprint, but the barrier to entry, both in complexity and cost, is too high.
What if we could empower any organization, in any industry, to calculate their carbon footprint?
What if we could make it a simple, guided, step-by-step experience that makes it impossible to get lost?
What if we could eliminate the barriers, technical, financial, and educational, that prevent organizations from taking climate action?

Metrics for success
To guide our launch and measure early traction, we identified a few key indicators of success
📈
2,000 organizations onboarded within the first year
This target was based on market sizing from our sales team and our strategy to capture the long tail of smaller organizations looking for a simplified carbon accounting solution.
👥
250+ monthly active users (MAUs)
Because carbon footprint tracking typically follows an annual cycle, our goal was to sustain a healthy core of active users engaging monthly, especially during key reporting windows.
💬
Tangible feedback showing ease and clarity
Beyond quantitative metrics, we aimed to gather direct user feedback signaling that Persefoni Pro made carbon tracking simple, intuitive, and actionable , a marked improvement over legacy tools or spreadsheets.
Persefoni’s goal was to lead the carbon accounting market. We had gained traction with our enterprise offering for organizations that:
Had dedicated sustainability teams who understood what they needed
Had the budget to commit to enterprise-level agreements
But a huge segment was being left behind. These were small and mid-sized organizations that needed or wanted to calculate their carbon footprint, but lacked the resources, knowledge, or budget to do so.
Enterprise Offering
Free Tier
Simple and supportive – Designed for users with zero sustainability experience
Accurate and credible – Not just another footprint estimator, but a true, reportable, auditable carbon footprint
Free (to try) – No upfront cost. Users could explore, get value, and upgrade only if and when it made sense for them
Once the journey was shaped, we interviewed potential users for feedback.
This step was critical. We needed signal from real users that this was the right approach.
One of my favorite product design principles came into play here:
A dollar in ideation costs 10 dollars in design and 100 dollars in development.
Validating early helps reduce risk and ensures we are solving the right problem in the right way.
I take notes in a spreadsheet during interviews, then import them into FigJam for affinity mapping.
At Persefoni, we always built high-fidelity designs alongside clickable prototypes. Every major feature was fully navigable from start to finish, with defined micro-interactions. This approach:
Gave engineers a clear reference
Helped us catch UX issues before they got expensive
Let stakeholders interact with the experience instead of just reviewing it
Engineers had been involved early on to stay aligned, but now we needed to turn designs into live software. On this project, I also stepped into a product manager role and wrote tickets for the engineering team.
This turned out to be a huge advantage. I was deeply familiar with the flow and design, so I could write clear and well-scoped tickets. It also helped close the gap between design intent and implementation.
Honestly, one of the best design tools is a well-written Jira ticket.
Persefoni Pro, our free carbon accounting tool, launched in Spring 2024, giving organizations an accessible way to measure and manage their emissions.
✅
6,000+ organizations onboarded within the 9 months
Originally targeting 2,000 orgs, we more than tripled our goal, demonstrating a clear demand for streamlined, self-serve carbon accounting—especially among smaller and mid-market companies.
✅
Averaging 500 monthly active users (MAUs)
We doubled our MAU goal, with sustained engagement throughout the year, including spikes around reporting season. This showed that users weren’t just signing up, they were returning regularly to manage and update their data and as we updated the tool with new functionality.
✅
Consistent user feedback highlighting clarity and ease-of-use
Users praised Persefoni Pro for its ease of use and appreciated the guided workflows and intuitive UI. This qualitative signal reinforced that we were solving real pain points and delivering meaningful value.
Users said
"Persefoni Pro simplified something I thought I was going to spend weeks on. Since then, it’s refocused us on what we’re going to do next.”
