Same dataset, three pricing shapes.
Per-contact cost is what one verified contact actually costs at typical use. Kustiq brackets the full span: list-builder workloads sit near the floor, single-account research sits near the ceiling.
| Tool | Per-contact cost | Per-seat fee | Verification quality |
|---|---|---|---|
| ZoomInfo | $1.20 to $3.40 | $15,000/yr min | HQ-stale, no SMTP |
| Apollo | $0.80 to $1.60 | $49/seat/mo | Email pattern guess |
| Kustiq | $0.15 (Pro) to $0.30 (entry) · no per-seat fee · SMTP-verified at request time | ||

Questions about tech detection.
How does Kustiq detect a company's tech stack?
Detection is deterministic and signature-based. The pipeline fetches the public surface of a domain, runs script-tag, header, DOM-attribute, and runtime fingerprints, and emits a confidence-scored list of technologies. Not header sniffing, not third-party stack databases, not a last-quarter snapshot. The fingerprint runs at profile time against the live site.
How fresh is the data on this hub?
Can I export a list of every company running a given tech?
Insight ($39/mo) exports up to 200 profiles per month as CSV, with the stack column included. Pro adds HubSpot sync. Extra credits cover ad-hoc list builds without a seat fee: $0.30 entry, $0.20 at the volume floor, $0.15 effective on Pro.
What does a full Kustiq profile include beyond the stack?
Stack detection is one column. The full profile adds SMTP-verified contacts, named decision-makers rather than generic inboxes. It adds the most recent buying signal: funding, hiring, press, or product launch. Returned in 60s. Free tier is 1 profile a week anonymous, 3 with an account. Try one.
Detection on demand
60s is all it takes to learn what a company runs.
Paste a domain. Kustiq returns the stack, contacts, and the buying signal that fired most recently. From $0.20. No seat fee.
