“Six weeks in and I'm still a little surprised by…”
Six weeks in and I'm still a little surprised by how well this holds up when you're not sitting at a desk. Half my week is split across client sites and co-working spaces, and the Hero Platform just works from my phone without feeling like a stripped-down afterthought. I built our first carbon reduction plan from a café, walking through each prompt in maybe eight minutes. That's not an exaggeration. For a team our size, where nobody has a dedicated sustainability role, having something that doesn't demand a proper setup session is genuinely refreshing.
The carbon footprint measurement tool is similarly accessible on mobile. Quick, no jargon, and the results feel credible rather than vague. My only tiny gripe is that uploading data from the smart plug rental occasionally requires a bit of fiddling on smaller screens, but it's a minor friction. Customer service has been prompt every time I've had a question, usually same-day. For what they charge, this is excellent value, and the CRAB workshop materials translated well to an async, remote-first team like ours.
