# Blekko: A Technology Company
Blekko was a web search engine company that aimed to provide superior search results compared to Google by combining human curation, social recommendations, and algorithmic transparency.[1][3] Founded in 2007 by Rich Skrenta, a prominent Silicon Valley programmer, Blekko raised $56 million in venture capital and operated until its acquisition by IBM in March 2015.[2][4][5]
The company's core mission centered on democratizing search through transparency and user control. Rather than relying solely on algorithmic ranking, Blekko employed human editors and professionals to curate results from 3 billion trusted websites, explicitly excluding content farms and low-quality SEO-optimized pages.[1][3] This approach positioned Blekko as an alternative to the "black box" nature of traditional search engines, appealing to users who valued data transparency and search customization.
Blekko emerged in 2007 when Rich Skrenta, an established figure in Silicon Valley programming, founded the company with the ambitious goal of challenging Google's dominance.[4] The search engine launched publicly on November 1, 2010, introducing a novel paradigm that prioritized editorial oversight and user agency over pure algorithmic automation.[3]
The founding reflected growing frustration with search engine optimization manipulation and content farm proliferation. Skrenta's vision attracted significant venture capital backing from major technology investors, signaling confidence in the alternative search model.[1] The company's early positioning as a "Google killer" resonated with professional searchers, data analysts, and SEO specialists who sought deeper insights into search mechanics and ranking transparency.
Blekko's competitive advantages centered on several distinctive features:
Blekko represented a broader 2010s movement questioning the concentration of power in algorithmic search and data collection practices. The company rode emerging concerns about search engine transparency, SEO manipulation, and user privacy—issues that would gain mainstream attention in subsequent years.[6]
The timing positioned Blekko within a cohort of alternative search engines (including DuckDuckGo and Wolfram Alpha) challenging Google's near-monopoly.[2] While these competitors ultimately captured limited market share, they influenced industry discourse around algorithmic accountability and user control. Blekko's emphasis on transparency and human curation prefigured later debates about AI explainability and content moderation that would dominate tech policy discussions.
Blekko's acquisition by IBM in March 2015 marked the end of its independent operation, though the company's technology and team were integrated into IBM's broader search and data capabilities.[5] The acquisition reflected IBM's interest in Blekko's advanced web-crawling and categorization technologies rather than the search engine itself.
While Blekko never achieved mainstream adoption against Google's entrenched position, its legacy persists in shaping expectations around search transparency and user agency. The company demonstrated that alternative search models could attract significant capital and user interest, even if they couldn't overcome network effects and market dominance. Today's renewed focus on AI transparency, algorithmic accountability, and user control suggests Blekko's core principles remain relevant—even if the company itself became a historical artifact of the 2010s search wars.
Blekko has raised $51.0M across 6 funding rounds. Most recently, it raised $30.0M Venture Round in September 2011.
