The best part of the job is the customers. We get to know each team that uses Grumbic, and most of what we ship comes from those conversations.

What we believe
The values we keep in mind every time we ship, design, or talk to a customer.
The math doesn't bend
Methodology stays consistent, even when results are inconvenient. We won't soften a calculation to make a deck flow better.
Sustainability is the work
Carbon work is hard, slow, and unglamorous. We chose it on purpose.
Trust is earned in the details
Trust isn't earned with a good pitch. It's earned when something goes wrong and we're still next to the customer.
Built with sustainability teams
We design alongside the sustainability, finance, and operations teams who use Grumbic every day.
Local before global
What works for a team in Santiago shouldn't be retrofitted for one in Madrid. Local context shapes the product.
We know the problem from the inside
We spent years inside the problem. We know it from both sides: the consultant's, and the software's.
Things people ask
The same questions, asked enough times that we wrote them down.
Who started Grumbic, and why?
Camilo and Faustino. Camilo spent over a decade in carbon footprint and energy efficiency; Faustino in tech. Companies already have most of the data to measure their footprint, but the process is still manual, slow, and expensive. The value isn't in measuring once, it's in doing it continuously. So we built that.
How big is the team?
Small, and we like it that way. That lets us stay close to every team that uses Grumbic.
How do you decide what to build next?
Most of what ends up in Grumbic started as a conversation with a customer. There's a roadmap, but it changes as we listen.
What's it like working with you as a customer?
Hands-on and very direct. We have a WhatsApp group with each customer, not a ticket queue. We talk to the teams every week.
Can I meet the team before signing up?
Yes, we prefer it. Most of our customers have spoken with someone on the team before paying for anything.
