Depth over breadth. 20 fields per credit, no per-seat caps.Seamless.AI scrapes contacts on demand with per-seat tiers and monthly credit caps. Kustiq returns a 20-field company profile per credit with SMTP-verified contacts, ICP scoring, and rule-based churn risk on every profile. Pro adds the churn dashboard with Stripe-grounded CLTV bands and a calibrated 90-day churn probability. No per-seat caps, and seats aren't billed separately.
§1The short version
Kustiq differs from Seamless.AI in three ways most outbound teams notice on day one.
- Sales intelligence per credit, not a single contact record. Kustiq returns a 20-field profile with verified contact, ICP score, and churn risk per credit. Seamless.AI returns one contact record per credit.
- Live SMTP verification, not pattern matching. Every Kustiq email is verified with a live RCPT TO handshake. Seamless.AI relies on email-pattern matching plus periodic validation.
- No per-seat fees, no per-seat caps. Kustiq Pro is $119/mo total for the team. Seamless.AI Basic starts around $147 per user per month, with monthly credit caps on lower tiers.
Search-volume vs scoring. Seamless wins on bulk-contact-search hours per day; the monthly-cap motion is built around SDR prospecting volume. Kustiq wins on which-account-deserves-a-call. If you can't tell which side of that line your team sits on, run both in parallel for a month. The faster surface for your scoring question is the one to keep.

§6Other Seamless alternatives we compete with
§7Six questions, six intents
01 · Real?Is Kustiq a real Seamless.AI alternative?
Kustiq is a Seamless.AI alternative for company profiles instead of single contact search. Seamless does real-time contact search. Kustiq returns a 20-field profile per credit with a verified contact, ICP score, and churn risk. For company-level prioritization, pick Kustiq. For bulk contact search inside a static-record motion, Seamless does that better.
02 · Catch?What is the catch · why is Kustiq cheaper?
Kustiq doesn't sell per-contact reveals at the volume Seamless ships for. $0.15 to $0.30 per profile, credits spent only on delivered profiles (failed runs auto-refund). Where Kustiq breaks down: at 5,000+ contacts a month, Seamless's per-record economics are competitive.
03 · MigrateCan I migrate my Seamless.AI lists to Kustiq?
Kustiq takes a Seamless company list: export it to CSV, paste or upload it into Contact Finder, and get up to 3 SMTP-verified contacts per company in minutes. Most teams run their top accounts through Contact Finder first and decide on Seamless renewal at the next cycle.
04 · MissingIs Kustiq missing anything Seamless.AI has?
Kustiq does not offer the real-time bulk contact search that Seamless sells for high volume work. Seamless sets monthly caps around SDR teams' prospecting volume. Kustiq has neither feature and doesn't fit that workflow.
05 · PricingHow does Kustiq pricing compare to Seamless.AI at 5 seats?
Kustiq Pro costs $119 / mo for five users with no per-seat fees. Five seats on Seamless Basic is ~ $735 / mo · $8,820 / yr. Five users on Kustiq Pro is $119 / mo · $1,428 / yr, with no seat fee and no per-seat caps. Kustiq covers the team for under 17% of the Seamless bill, with sales intelligence on top.
06 · Both?Can I use Kustiq and Seamless.AI together?
Kustiq can run with Seamless.AI when Kustiq scores companies before contact search. Kustiq writes ICP-fit and churn-risk back to HubSpot. Seamless pulls additional contact depth at qualified accounts. Both can sync to the same CRM company records.
