Launching in 10 days: free color analysis from an actual photo. Poke holes in my pitch?

siOsi reads one selfie or any picture and returns your 12-season color type, undertone, gold vs silver, and whether your hair color fights your skin tone then grades the makeup you're actually wearing: flash white-cast, oxidation, coverage. 1st check-up: free, instant, no signup, 9 languages.

The one-liner I'm taking into launch day: "A quiz asks what color you are. siOsi looks." If that reads wrong to you, I'd rather hear it now than on the 22nd.

What made you build your product? Drop the real story below.

I'll go first.

Six months ago I was running growth for a small team. Seven tools open at once. I'd draft something in Notion, paste it into the CRM, copy the numbers from Analytics into a Sheets report nobody read, then schedule the post in a different tab. Every week the same loop. Nothing talked to each other, so I was the integration layer.

The customer complaint I almost ignored became our best product feature.

We had a user who submitted four support tickets in two weeks about the same thing: she couldn't filter her dashboard by date range without exporting to CSV first.

I'll be honest - my first read was that she was a power user with niche needs. We had bigger things to build.
