Tech Stack Change & Displacement Intelligence

Find companies that appear to be removing or replacing competitor software. This Apify Actor monitors observable website technology changes and turns them into explainable technographic sales signals for B2B sales, RevOps, competitive intelligence, and AI agents.

Instead of answering only “what technology does this company use?”, it helps answer “what changed, what may have been replaced, and which accounts deserve research now?”

Open the Actor on Apify

Start here: turn public website changes into account research

Who it's for: B2B prospecting agencies, RevOps teams and technographic data products monitoring target accounts.

Pilot: Provide 20 company domains and one or two technologies that are visible on public websites (for example chat widgets or marketing tags). Run an initial baseline, then a second comparable observation later. Review only evidence-backed additions, removals and plausible same-category replacements.

Important: A single scan does not establish that a company has left a competitor. The first observation establishes a baseline. A change requires at least two comparable observations and may still return INSUFFICIENT_EVIDENCE. We do not infer confirmed buying intent or internal CRM migrations from website tags.

Quick start — one domain, then repeat later

This is an Apify Standby API/MCP product. Clicking a normal Start run on Apify only returns a readiness record; use the hosted HTTP endpoints or MCP tools to analyze domains. Use your own APIFY_TOKEN from Apify; never publish it.

curl -X POST 'https://tryva--competitor-displacement-intelligence.apify.actor/v1/change' \
  -H "Authorization: Bearer $APIFY_TOKEN" \
  -H 'Content-Type: application/json' \
  -d '{"domain":"example.com"}'

Repeat the same request later to compare public signals with the stored baseline.

Scan a target account list

curl -X POST 'https://tryva--competitor-displacement-intelligence.apify.actor/v1/displacement/search' \
  -H "Authorization: Bearer $APIFY_TOKEN" \
  -H 'Content-Type: application/json' \
  -d '{"competitors":["Intercom"],"replacement_candidates":["Crisp"],"domains":["example.com"],"min_evidence_score":70}'

Results include accounts, scanned, failed and evidence scores. An empty accounts array is a valid result, not a promise that no real software change occurred. The technology must be publicly observable and fingerprints must support it.

Pricing, usage, measurement

• Current Store events: $0.01 per scan, $0.02 per change comparison, $0.03 per displacement analysis, where charged under the Apify billing contract.
• No prospect email addresses or private internal technology usage are supplied.
• For pilot evaluation, track valid scanned domains, comparable observations, change detection precision, and human-verified useful signals. Evidence score is not purchase probability.
• Prefer synthetic/sample domains for demonstrations and respect the target site's access rules.

Want to pilot? Message the Tryva publisher via its Apify Store profile with a 20-domain target list and the publicly visible technology categories you're interested in.

Find companies leaving competitor software

Use the Actor when you want to monitor a target-account list for evidence that a competitor technology was removed and a plausible same-category replacement appeared.

Example:

{
  "competitors": ["Salesforce"],
  "replacement_candidates": ["HubSpot", "Pipedrive"],
  "domains": ["company-a.com", "company-b.com"],
  "min_evidence_score": 70
}

Typical questions it supports:

• Which target accounts appear to have removed Salesforce, HubSpot, Marketo, Intercom, Segment, or another monitored technology?
• Which companies show a possible technology replacement?
• Which accounts changed their visible tech stack since the previous observation?
• Which technology-change signals have enough evidence to justify follow-up research?

The Actor does not claim confirmed buying intent, an active procurement process, or a confirmed internal migration. It reports observable public-web evidence and conservative inferences.

Technology stack change monitoring

The Actor keeps bounded observations for monitored domains and compares scans over time.

Available REST operations:

• POST /v1/scan — inspect the currently observable website technology stack.
• POST /v1/change — compare the current observation with stored history.
• POST /v1/displacement/search — scan up to 1,000 domains for competitor-removal and replacement evidence.
• GET /v1/history/{domain} — retrieve recent observations for one domain.

This makes it useful as a lightweight tech stack change API, competitor technology monitoring API, and technographic signal source.

Sales trigger and RevOps workflows

Common workflows include:

• Competitor displacement prospecting — prioritize accounts where a named competitor appears to disappear.
• Technographic sales signals — use stack changes as a reason to research an account now.
• RevOps account prioritization — enrich a target-account list with evidence-backed change signals.
• Competitive intelligence monitoring — track additions, removals, and likely same-category replacements.
• AI sales agents — call the same engine through MCP and return structured reason codes.
• Agency research — monitor client or prospect ecosystems for visible vendor changes.

MCP tools for AI agents

MCP is available over Streamable HTTP at /mcp.

Tools:

• scan_technology_stack
• detect_technology_change
• find_competitor_displacement
• get_technology_history

The MCP surface uses the same snapshot, comparison, evidence, and quality-gating engine as the REST API.

What does a result mean?

Signals include:

• NO_CHANGE
• OBSERVED_ADDED
• OBSERVED_REMOVED
• LIKELY_REPLACEMENT
• INSUFFICIENT_EVIDENCE

Machine-readable reason codes include:

• competitor_removed
• competitor_added
• same_category_replacement_detected
• scan_quality_comparable
• scan_quality_insufficient
• change_confirmed
• insufficient_evidence
• no_material_change

A LIKELY_REPLACEMENT requires reliable removal and addition evidence, a shared technology category, adjacent observations, and comparable scan quality.

A degraded scan exposes provisional_removed and cannot produce a removal or replacement claim.

How is this different from a one-time tech stack detector?

A one-time technology detector tells you what is visible now. This Actor adds a time dimension: it stores bounded observations, compares them, and reports additions, removals, and possible same-category replacements.

That makes it useful when the business question is not only “who uses X?” but “who appears to be moving away from X?”

Data source and evidence

The detector uses Opentechalyzer built-in MIT fingerprints with --no-external.

No external intent-data feed, Wappalyzer database, private telemetry, or paid enrichment provider is required by the Actor.

Snapshots and bounded history use the named Apify Key-Value Store technology-change-buying-signals-v1.

Evidence score is not purchase probability. Public website technology evidence can be incomplete, blocked, delayed, or unrelated to an internal system of record. Treat every displacement signal as a research trigger, not as confirmation of a buyer or migration.

Pricing

Apify PAY_PER_EVENT:

• Technology scan: $0.01/domain
• Technology change detection: $0.02/domain
• Competitor displacement analysis: $0.03/domain

Displacement analysis is the primary paid event.

FAQ

How can I find companies that stopped using a competitor?

Provide the competitor technology, optional replacement candidates, and the domains you want to monitor. Repeated observations allow the Actor to detect when public website evidence for that technology disappears and whether a plausible replacement appears.

Can I use this as a BuiltWith or Wappalyzer alternative?

It overlaps with technology detection, but its main purpose is different: change detection and displacement monitoring. It is designed to compare observations over time and expose evidence behind additions, removals, and likely replacements.

Does a removed technology mean a company is ready to buy?

No. A removal is an observable technographic signal, not confirmed purchase intent. Use it to prioritize account research, not to claim knowledge of an internal buying process.

Can I monitor many companies?

Yes. /v1/displacement/search accepts up to 1,000 domains per request.

Can an AI agent use it?

Yes. The Actor exposes MCP tools for technology scanning, change detection, displacement search, and history retrieval.

What is competitor displacement intelligence?

Competitor displacement intelligence is the process of identifying evidence that a target account may be removing or replacing a competing technology, then using that evidence to prioritize research, monitoring, or outreach.
