Pass a company domain and get back a flat list of the technologies that company runs, resolved by a multi-provider waterfall for 1 credit.
Find Company Techstack is a SyncGTM MCP tool that takes a company website domain and returns the technologies that company runs. It uses waterfall enrichment, trying providers in sequence until one returns a stack, and charges a flat 1 credit per lookup. It resolves a stack from a domain, so it answers "what does this account run" and not "which companies run this tool".
Takes one parameter, `domain` — a bare company website domain like `stripe.com`. Deep URLs, LinkedIn pages and company names are not accepted, and there is no batch or filter parameter, so 40 domains is 40 calls.
Runs waterfall enrichment: providers are tried in sequence until one returns a stack, so you never pick a vendor yourself.
Returns two fields — the `domain` you passed and a flat `technologies` array of vendor names, e.g. `["HubSpot", "Segment", "Cloudflare"]`. No categories, no confidence scores, no install dates; grouping those names into CRM or CDP is something your client does after the call.
Does not return emails, phone numbers, funding, revenue, headcount or industry. It is a stack lookup and nothing else.
Does not run in reverse. "Which companies use HubSpot" is a different question, and the BuiltWith-backed reverse tool is still on the catalogue's Coming soon list.
Costs 1 credit per lookup, flat — half the price of `enrich_organization` (2 credits), which returns technologies inside a full firmographic record. An empty stack still bills 1 credit.
Download the skill file — it saves as find-company-techstack.zip.
In Claude, open Settings → Capabilities → Skills and upload the .zip (or unzip the find-company-techstack/ folder into .claude/skills/ for Claude Code).
Connect the SyncGTM MCP server. Browser sign-in, no API key — follow the setup guide for your client at docs.syncgtm.com/mcp_server/setup.
Type /find-company-techstack and paste your domains, one per line, as bare hosts: `stripe.com`, not `https://stripe.com/pricing` and not a LinkedIn page.
The thing worth tuning is not a tool parameter — `domain` is the only one the tool takes. It is the flag rule you give the skill: name the vendors that decide the outcome ("flag anything running HubSpot") and you get a filtered answer instead of every vendor for every account.
Confirm an account already runs the CRM or CDP your product plugs into before an SDR opens with an integration angle. You match the partner's name against the returned list; accounts with no match go to a different message.
Flag the accounts whose stack names a direct competitor and quote the specific tool, so the AE can time the pitch against the renewal and lead with the switch story.
Score inbound demo requests on the company domain from their work email, then route accounts whose list contains Salesforce to the enterprise queue and HubSpot accounts to mid-market. Skip free-mail domains — gmail.com returns nothing and still costs 1 credit.
Write the returned vendor names into the empty Tech Stack field on account records so territory rules, playbook triggers and list views can actually fire on it.
Outcome: A CSV of the accounts whose stack names a direct competitor, each with two to three owning contacts and deliverability-checked emails, ready to load into the displacement sequence.
Outcome: Every inbound request scored and routed the same morning, with 2-credit enrichment spent only on accounts that already run the integration.
Outcome: A 60-row tiering sheet showing stack, traffic and tier per account, where only the top 15 consumed 3-credit calls and carry named contacts.
Paste any of these into Claude once the skill is installed and the SyncGTM MCP is connected.

Stop after 40 and report credits used.Check my credits first, then run find_company_techstack on these 25 open-opportunity domains and return a table of domain, technologies, and whether Salesforce appears in the list. Cap it at 25.For notion.so, monday.com and airtable.com, run find_company_techstack and tell me whether Google Analytics, Amplitude or Mixpanel appears in each list. If a stack comes back empty, say empty — do not guess.Run find_companies with industries Software Development, employee_count_ranges 201-500, countries United States and limit 50, then run find_company_techstack on each returned domain and show me only the ones whose list contains Segment, RudderStack or mParticle. Report total credits used.Pass bare domains. `stripe.com`, not `https://stripe.com/pricing` and not a LinkedIn page — `domain` is the only parameter this tool takes.
Ask for the filter and name the vendors. The response is a flat list of names, not categories, so "flag the ones running HubSpot" is a match your client can actually make; "list all technologies for 60 companies" is a wall of text.
Treat an empty stack as a real answer. Coverage is thinner for small and private companies, and an empty result is common and valid — never let the assistant fill the gap with a guess.
Do not pay 2 credits for a 1-credit question. `enrich_organization` also returns technologies but costs double; use it only when you need industry, size and funding in the same call.
Dedupe and cap the batch before you run. 1 credit per lookup means a 400-domain paste is 400 credits, and empty results still bill — run `check_credits` (free) first.
Remember it only runs one direction. The reverse lookup is not on the server yet, so to answer "which companies use HubSpot" build the domain list with `find_companies` (0.3 credits per result) first, then check each domain here.
