US contact data and enrichment API, $50K a month, self-reported: priced monthly

LeadFuze sells US B2B and B2C contact data, identity resolution, enrichment API, and data licensing. Its $50K a month was founder-reported on the Indie Hackers product page (not independently verified), as of September 30, 2026.

What it actually sells

LeadFuze provides US B2B and B2C contact data with monthly refreshes, identity resolution, an enrichment API, and data licensing. Its site says it provides “the totality of US B2B and B2C data with monthly refreshes to fuel innovative tools.”

The product list includes real-time contact verification, automated list building, enrichment for email addresses and LinkedIn URLs, custom segmentation, and identity graph delivery through S3 and Parquet. The site says it can identify website visitors through a pixel, including the actual person visiting.

How it charges

A full data license costs $1,500 to $2,000 monthly depending on term, with monthly updates. The site says, “However, we are licensing this for $1,500 to $2,000 per month depending on the term.”

Where customers come from

The site presents several product-led entry points: an enrichment API, website visitor identification through a pixel, webhook delivery, and cloud data delivery through S3 and Parquet. The site says, “Real-time enrichment for any identifier. Built for apps needing instant context.”

What stands out

The site lists more than 269 million profiles and more than 131 million mobile numbers. It says the B2B database verifies contact information in real-time, builds lists automatically, and integrates with existing tools. The site also lists 50+ fields per visitor for turning anonymous traffic into enriched, qualified leads.

Where it sits in the data

LeadFuze's $50K a month is higher than 82% of the 6,604 projects with founder-reported monthly revenue in our dataset; the median across them is $2K. Snapshot: 2026-09-30. The dataset only covers founders who chose to publish their numbers, so it leans toward businesses that work; use it for scale, not as an average.

Currency

All figures are in US dollars as published. A rough yuan or euro conversion is not applied here because prices, taxes and acquisition costs differ by country.

Could you build something like this?

In my view, this needs real work. The buyer would be a business building sales, marketing, outreach, advertising, or contact-driven applications. Distribution would have to come through developer channels, direct sales, integrations, and useful product surfaces such as APIs, webhooks, pixels, and data delivery.

The hard parts are maintaining accurate data, handling verification and identity resolution, keeping monthly refreshes reliable, supporting different delivery formats, and managing customer integrations. Regulation, data permissions, support load, and competition would also matter.

Verdict: Hard to replicate.

One thing to take from it

My view is that the product shape connects contact data, identity resolution, enrichment, visitor identification, and several delivery methods. The pages show monthly licensing, product-led interfaces, and published data coverage, with reported revenue of $50K a month, founder-reported on the Indie Hackers product page (not independently verified), as of 2026-09-30.
