About · solo build, in public

A $100B industry, still counted by hand.

Sponsorlens is one founder building the measurement layer for sponsorship. Social analytics run today. Broadcast computer vision is in development. Everything ships in public.

Our mission

Make every euro of sponsorship measurable — and defensible.

Sport is the last giant industry where ten-figure budgets move on the strength of a slide deck. Brands can't prove their ROI. Clubs can't prove their value. Both sides leave money on the table, every season.

I'm building the measurement layer: contracts, matchdays, jersey deals, LED rotations, viral posts, turned into numbers a CFO can sign off on.

If you care about sport and you care about craft, you'll probably like what I'm building.

Illustrative scenario · not a client result

What a 20-week pilot could look like.

An illustrative pilot: social analytics and per-sponsor reporting wired against a real season schedule, with match-day computer vision in active development. Every number below is a target we would commit to, not a result — Sponsorlens has no clients yet.

How we work

Four values, non-negotiable.

Written here because it's easier to stay accountable in public.

01

Transparent by default

Public pricing. Public roadmap. A public study. If I can't explain a number, I don't ship it.

02

Measurement is a craft

I build models I would bet on, not ones that happen to make customers feel good. Integrity over vanity.

03

Customer-first, truly

Support goes straight to the founder. You won't hear 'I'll escalate it', you'll hear 'I'm shipping it.'

04

Data you'd trust with your kids

EU-hosted by default, never used to train shared models, deleted on request. Your sponsors deserve that.

Founded by

A solo founder, shipping in public.

Sponsorlens is an independent project, built from scratch, without a pre-existing team or external funding.

Our story

A roadmap built in the open.

  • 2026

    An idea, then a prototype

    Sponsorlens starts as a solo side-project, a hunch that sponsorship measurement deserves a real data layer, not a PDF recap.

  • 2026

    Public build

    The site goes live. The product roadmap is public from day one, features ship small, often, and in the open.

  • 2026

    The public study

    CA Osasuna measured from public data: 283 posts in 90 days, one broadcast highlight read frame by frame, a weekly report every Monday.

  • Next

    The first design partners

    Now looking for the first club to run a real pilot. One partner at a time, shaped around real sponsorship workflows.

Design partners

Want your sponsorship measured, not estimated?

I'm looking for the first design partners: clubs, leagues and brands who want their exposure measured. You get the founder, the public roadmap, and a report every Monday.
