The Contact Data Layer for Apps

Visit LeadFuze

LeadFuze is no longer the prospecting application it was known as. Its own signup page carries an "Important Announcement: We have shut down direct software access and are now exclusively offering a full data license with monthly updates." What remains is a data business - an identity graph of US B2B and B2C profiles, sold as a bulk licence, an enrichment API, and a visitor-identification product - aimed at companies building their own tools rather than at sales reps.

From official docs
data/enrichmentsignals/intent

Status: Pivoted, with the original product discontinued. The vendor's start page carries an explicit shutdown notice: "We have shut down direct software access and are now exclusively offering a full data license with monthly updates." The company and the data business are live, but the prospecting software that most directory listings still describe is not.

Core capabilities

Vendor's own claim
  • Full data licence: the identity graph delivered in bulk with monthly refreshes, via S3 and Parquet, with custom segmentation
  • Enrichment API: submit an email address or LinkedIn URL, receive 50+ fields in real time
  • Identity resolution / visitor identification: a pixel that resolves anonymous site traffic to a person, not just a company, with 50+ fields per visitor and webhook delivery
  • Claimed B2B-to-B2C and cross-device identity bridging into a single unified profile
  • Native integrations plus a Zapier connector to 1,000+ tools

What is LeadFuze

Vendor's own claim

A data supplier positioned as infrastructure. The vendor claims 269M+ profiles established since 2014, broken down as 131M+ mobile numbers, 176M+ email addresses, 101M+ LinkedIn profiles, 91M+ with revenue data and 124M+ with net worth data, refreshed monthly. The pitch is explicitly to builders - "Everything you need to build next-generation sales and marketing tools" - with three delivery shapes: bulk Parquet on S3, a lookup API, and a website-visitor pixel. The net-worth and B2C consumer data are notable and unusual for a tool that sits in B2B sales directories.

Ideal customer profile

Our read

Companies building contact-driven products, agencies running outreach and ad-targeting for clients, and data teams that want to own an identity graph rather than query someone else's UI. The delivery formats - S3, Parquet, webhooks - say plainly that the buyer is expected to have engineers.

Who should look elsewhere

Our read

Anyone looking for the LeadFuze they remember. Direct software access has been shut down by the vendor's own announcement, so there is no application for a rep to log into and build lists in - if you wanted a prospecting UI, this is now the wrong product entirely. The commercial floor has moved with it: the vendor states the licence runs $1,500-$2,000 per month depending on term, which is a data-infrastructure budget, not a seat purchase, and the entry point is a request-access form rather than a signup. The graph is also US-only by the vendor's own description ("the totality of US B2B and B2C data"), so international coverage is not on offer. And person-level visitor identification plus consumer net-worth data is a category that will need a serious privacy and compliance review in most organisations before it can be used at all.

Tools in the same layer

Our read

No curated rival set covers this tool yet, so these are simply other tools in the same architectural layer and product form. Treat it as a starting point, not a shortlist.

LeadFuze FAQ

Can I still sign up and use LeadFuze as a prospecting tool?

No. The vendor's own start page states: "We have shut down direct software access and are now exclusively offering a full data license with monthly updates." If you are here because of the prospecting application, that product is gone.

From official docs
What is on offer instead?

Three things: a full licence to the identity graph delivered as Parquet on S3 with monthly refreshes and custom segmentation; a real-time enrichment API that takes an email or LinkedIn URL and returns 50+ fields; and an identity-resolution pixel that turns anonymous website traffic into named, enriched individuals with webhook delivery.

From official docs
What does the data licence cost?

The vendor states $1,500 to $2,000 per month depending on term, and frames that against "$10,000 to $20,000 per month from other providers". We are recording this as a vendor statement, not as retrieved pricing - LeadFuze publishes no pricing page, and we could not retrieve one, so there is no plan structure, no tier breakdown and no confirmation of what the term commitment is.

Vendor's own claim
How big is the dataset?

The vendor claims 269M+ profiles, including 131M+ mobile numbers, 176M+ emails, 101M+ LinkedIn profiles, 91M+ records with revenue data and 124M+ with net worth data, established since 2014 and refreshed monthly. These are the vendor's own figures; we have not sampled the data.

Vendor's own claim
Does it cover markets outside the US?

Nothing we retrieved indicates international coverage; if you need it, ask before you sign.

From official docs
Does it identify individual website visitors or just companies?

Individuals, by the vendor's claim - the licence description says it detects website visitors via pixel, "identifying not just the company but the actual person visiting", with 50+ fields per visitor and behavioural insights. That is a materially different privacy proposition from company-level identification and should be reviewed as such.

Vendor's own claim
Is there usable API documentation?

We do not know whether documentation is behind authentication or simply absent.

Our read
Which tools does it integrate with?

We cannot tell you. Zapier is named as the fallback, connecting to 1,000+ tools.

Our read

Verify before you buy

  • A pricing page - none exists that we could find, so the $1,500-$2,000/month figure is an unverified statement on a marketing page rather than published pricing
  • The contents of the API docs page (it rendered as the words "API Docs" alone)
  • The list of native integrations (the integrations page rendered its introduction but not the list)
  • The date the software shutdown took effect, and whether existing customers were migrated
  • Data provenance and consent basis for the B2C/consumer attributes
  • Social profiles
