Potential co-founder asking for 25% equity and 100k salary

I am the solo founder of a bootstrapped startup and we have been around since early 2024, in Gen AI Space, Silicon valley.

We recently crossed 1.2MM in LTR and have built a good customer base.

I have been working with someone who I feel might be a good cofounder but they are asking for 100k salary and 25% equity.

Both seem too high to me, I initially offered 15% equity.

Edit: it seems high to me hence the question. Edit 2: 7 employees so far (all contract)
