Only verified people you approve get through.
haih screens the sales outreach coming at you, so only verified people you’ve approved can reach you, and your data stays yours.
Every request reviewed by a person
The problem
You can’t tell who’s real anymore.
Sales emails, calls and DMs all look personal now, whether or not anyone wrote them. So you stop reading, and somewhere in the pile is the one vendor who could have helped.

How haih works
haih checks everyone at the door.
A person reviews every buyer and seller before they can reach anyone. You decide who you talk to and can change your mind anytime.
Your profile goes where you go.
Your profile, preferences and relationships belong to you, not a vendor’s database. Change jobs and they come with you.
For buyers
You decide who gets in.
Your lobby is where verified requests wait. Only sellers you’ve chosen reach you, and your needs stay private until you share them.
Up to 10 at a time. Accept, snooze or decline.
No one reaches you without your say. A small lobby keeps attention honest.
2 verified1 invited
Sales email, sorted.
Connect your email. haih turns vendor outreach into cards you can flag, dismiss or invite into your lobby.
Compare vendors side by side, weighted by your needs.
Sellers never see your needs unless you turn them on.

Connect your email.
haih finds vendor outreach in your inbox, pulls out what’s actually offered, and matches it to what you’re working on.
Set your needs and your limit.
Tell haih what you’re evaluating and how many vendors you’ll see. Everyone else waits.
Decide in one place.
Verified vendors side by side, ranked against your priorities. Connect when ready, decline without awkwardness.
