Know a prospect's stack before you spend a sequence slot
Paste a domain. In seconds you see the tools a prospect actually runs — and a one-line read on whether they're worth a touch.
- CRM, analytics, auth and payments, grouped by what they mean for the sale
- A verdict, not a logo list: qualify, route, personalize, or skip
- Reads through React & Next.js SPAs that leave Apollo and BuiltWith empty

The 20 seconds before you decide to touch an account
You have more accounts than sequence slots. The research to qualify one is a tab-hop through LinkedIn, their homepage, and a job post that lies. So most reps skip it and send “just checking in.”
A scan collapses that into one card with a call:
Manual pre-call research
Three tabs, ten minutes, and the job post lies.
Qualify
— right stack, worth the slot
Route
— send to the rep who owns this play
Personalize
— here's the opener their stack earns
Skip
— no fit signal, don't burn the touch
Skip — no CRM or MA detected
The skip is the point. TechSpy will tell you an account isn't worth a touch instead of padding a score to look useful.
The output is a brief, not a logo wall
Every scan returns the detected tools grouped by what they mean for the sale, a fit read, the angle to open with, and an explicit flag when it's not worth chasing. Each tool carries a confidence marker (High / Medium / Low) so you know what's a solid signal versus a maybe — and when a scan is blocked, it says so instead of faking certainty.
No 0–100 fit score. A verdict, the evidence behind it, and what to do next.

Contrasting example
Detected stack → the play
The pattern in the scan tells you the move. This is the row you'll screenshot.
Job posts lie. The footprint doesn't.
“We already pay for enrichment.” Sure — and half of it is aspirational. A job post asking for Marketo experience isn't a Marketo deployment. Self-reported stacks are what a company wants to be running, dated whenever someone last updated a form.
TechSpy reads what's serving traffic right now, timestamped. And when Cloudflare or a bot wall blocks the scan, it tells you — no invented 100%.

You're not going to leave Salesforce to check a scan. So push the detected stack and suggested angle into Salesforce, HubSpot, Clay, or Slack via Zapier or the API — enrich the account fields, drop a brief on the record before the call.
Or export the brief as a PDF and attach it. Zapier, the API, MCP and the CLI come with Plus (30 scans a day) and Max (unlimited scans); PDF export is on Max.

Worth a look if the stack changes your pitch
For
- Integrations & add-ons that plug into a specific CRM/stack
- RevOps / analytics / attribution
- Security, auth & compliance sellers
- Devtools & API products
- AEs who personalize by stack
Not for
- Pure-volume outbound where every account gets the same email
- Offers that don't change based on the prospect's tools
Scan an account. If the stack doesn't change your angle, skip it.
That's the whole rule. Run a domain, read the brief, decide in seconds whether it earns a slot.
