Powering the clean energy transition
We build Payaca, the AI-native software that solar, heat pump, battery and EV charger installers run their whole business on, from the first inquiry to the final invoice.
What we build
Payaca is the CRM, the project management tool and the field service system for solar, heat pump, battery and EV charger install businesses. Each job lives in one record, from the design or first enquiry through the quote, the install and the permit, inspections and PTO to the final invoice.
Agent Dave, the AI built into Payaca, works on that same data when your team asks him to. He can write up and price a proposal, draft an automation for you to check before it goes live, or tell you which invoices are still unpaid.

Our vision. To inspire and enable a world powered by renewable energy, where businesses play a pivotal role in achieving a sustainable, net-zero future.
Our mission. To build intuitive software that empowers businesses to scale renewable energy operations and drive the shift to a sustainable future.
The Payaca playbook
How we operate, what we value, and what we expect from each other.
Why we exist
The transition to sustainable energy is being held back by operational complexity. We exist to fix that. We build one system that lets clean tech businesses run more installs without losing control, from design or inquiry to payment, so they can focus on the critical work of building a clean energy future.
Operating principles
Take action. If you see a problem, address it. Don't wait for permission or consensus. Make the best decision you can with the information you have, then move forward. Ask for opinions but not permission.
Be transparent. We share information openly: product roadmap, key metrics, customer feedback, and our mistakes. We document our decisions so future team members understand why we built things the way we did.
Design for simplicity. Our customers don't have time for complexity. Neither do we. Before we add a feature, a setting, or a workflow step, we ask: what's the simplest version that solves the real problem?
Challenge ideas, support people. Strong disagreement on product direction or technical approach is expected and healthy. Arguments should win on merit. But supporting people completely means active help, not passive encouragement.
How we work together
Decisions
Most decisions should be made by the person closest to the problem. If you're accountable for shipping a feature, you have authority over the technical approach. Escalate only when you need input you don't have or when the decision has significant cross-team impact.
When things break
Everyone is responsible for fixing critical issues proportional to their expertise and role. If a customer's quote generation is broken before a big install, the person who can fix it fastest owns it, regardless of whether it's "their code" or "their job."
Failure and learning
Failure is fine if you learn from it and share what you learned. Shipped a feature that customers didn't use? That's valuable data. What's not fine is repeating the same mistake or hiding problems until they become customer-visible disasters.
What we look for
We hire and promote based on:
- Results: Do you ship features that customers use? Do you solve real problems?
- Customer empathy: Do you understand the operational challenges of a scaling installation business?
- Judgement: Do you make good decisions with incomplete information?
- Impact: Improvements to the product and team.
- Collaboration: Do you make others more effective?
We don't optimise for credentials, years of experience, or likability. We don't tolerate high performers who damage the team.
We're building the one system that helps clean tech companies scale and accelerate the clean energy transition. That requires a team that ships high-quality work, operates with integrity, and is obsessed with helping our customers grow.
