Source-derived summary

Nextag was an independent price comparison service website for products, travel, and education. It started as a website where buyers and sellers could negotiate prices for computers and electronics products. From 2000, the business model focused on comparison shopping. NexTag also owned Hamburg, Germany-based Guenstiger.de. It provided functionality for tracking the historical prices of a product across various sellers.

Nextag's headquarters were in Redwood Shores, California.

In June 2007, Providence Equity Partners purchased a two-thirds majority of the company for $830 million, valuing NexTag at approximately $1.2 billion. Los Angeles-based private equity firm Regent purchased the company in March 2015.

The NexTag.com website went offline on or about December 28, 2018, with no formal public closure announcement. Industry sources reported in January 2019 that the company had gone out of business.

Editorial analysis

Why this record matters

“NexTag” is worth following because a concise public description often conceals a longer documentary argument. Here, NexTag, price and comparison provides the most credible route into that argument.

Evidence profile

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 16, 2026. The linked authority identifier is Q1816104. 2 of 2 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 2000, 2007, 2015 and 2018.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
