Who builds this, and why.

Larssoni is built by Oscar Wirén, an independent maker in the UK.

For years I made dashboards for other people, then watched them die the moment I sent them: a login wall, a blank page, or a PDF that was wrong by Tuesday. The work was good. Getting it in front of someone was the part that kept breaking.

So I built Larssoni to fix exactly that. The hard part was never making the dashboard — you already did that, and it’s good. The hard part is giving it a home: a link that always opens, for exactly the people you choose, with numbers that keep themselves up to date from your spreadsheet. That’s the whole product, and I kept it that focused on purpose.

I try to be honest about the edges. Some dashboards can’t update themselves, and you’ll know before you pay. Your links keep working if you stop paying, and you can export or delete everything in one click — no email to support, no dark patterns. Where something is still a draft — the legal pages, for now — it says so. I’d rather under-promise than have you feel misled.
