Ansafi vs PredictLeads

Three differences that matter, and the places where PredictLeads is genuinely better.

1. What you pay for

PredictLeads prices per API call — roughly $0.002 to $0.04 each, from about $40/mo. That is fine when you know exactly which accounts to ask about, and expensive when you do not: every exploratory query has a meter on it. Ansafi prices per technology watched. Once a competitor is in your set, every company running it is included, with no per-record cap. Records are bounded by how much change actually happens; the number of competitors you sell against is not. See pricing →

2. Where the data comes from

Ours is built on HTTP Archive — an Internet Archive project backed by Google, Mozilla, Fastly and Akamai, which loads millions of real sites in a real browser every month and publishes the dataset openly. If a row looks wrong you can open the prospect's site and check it in about thirty seconds. PredictLeads aggregates from sources you cannot re-run yourself. How it works →

3. What is in a row

A technology lookup tells you the prospect uses the thing you filtered on. Ours carries their whole detected stack — an average of 17.3 technologies per prospect across 716,977 profiled domains — with categories, version strings and the crawl month the signal came from, so your team can audit a trigger before anyone sends on it.

Where PredictLeads is better

Signal breadth. They track hiring, funding, job posts and news events alongside technology. We track technology and the changes to it, nothing else.
Freshness. Event-driven signals land far faster than a monthly crawl published four to six weeks after the month it covers.
Entry price. About $40/mo gets you started against our $249/mo Starter, if your volume is genuinely small.
Customer proof. They publish named customer testimonials. We are newer and do not have them yet.
Large enterprises. Big firms run marketing and commerce on subdomains a homepage crawl never sees. This data is strongest in the mid-market.

If you want many signal types on a metered API, buy theirs. If you want to watch a set of competitors, see every company that leaves one, and audit the source yourself, that is this. Browse the catalogue →
