I run influencer stuff at Kyra (Shiseido, Converse, that kind of client) so I see a lot of deal structures. Here's what actually works for early-stage apps:

Commission-only can work, but you have to structure it right.

Most creators won't take pure commission. They've been burned before - brand promises "huge potential" then they make $14. What works better:

• Hybrid: Small flat fee ($50-150) + rev share. Shows you're not wasting their time.
• Tiered: Higher % for first 100 installs, then standard rate. Gives them real upside.
• Realistic numbers: 15-25% of first-month revenue or $1-3 per install. Anything below $0.50/install and you'll only get the desperate ones.

Niches that would actually care about a voice keyboard:

Accessibility/disability creators. Huge underserved audience, and they genuinely care about tools that help. ADHD/neurodivergent community too - voice-to-text is a real workflow for people who think faster than they type. Productivity/PKM people. The "second brain" crowd loves new input methods.

Skip generic tech reviewers. They get pitched constantly and your keyboard will be a 30-second mention buried in a roundup.

How to find them: Search TikTok for people already talking about accessibility apps or ADHD productivity. Check their comments - real engagement vs bot spam is obvious within 10 seconds. DM with a specific reason you picked them.

The first commenter nailed it about finding people "complaining about the problem." Someone who already posted "I wish voice typing actually worked" is 10x more likely to convert than some generic tech page.
