Where they pull apart

Debounce

Stands out: A verification API with a public per-check floor and a free start, so no $35/mo gate if your list is small.

Watch out: Per-check looks cheap until you run a million rows. There is no timed trial; free credits are the on-ramp.

Not the right fit for

People who need a finder
Teams that want a sequencer
Buyers who need a flat $32/mo all-you-can-verify

Kickbox

Stands out: Unknown results are refunded as credits, so you do not pay for a check that returns no clear answer.

Watch out: Packs are paid upfront, not billed monthly. Very large volumes move to custom pricing through sales.

Not the right fit for

Buyers who want a flat monthly subscription
Teams that need lead search and verification together
