Company profile
researched Aug 2026Perfect Audience was a San Francisco-based self-service display and social advertising platform that let businesses retarget prior website visitors. Advertisers installed a single JavaScript tracking tag, which set an anonymous browser cookie and grouped visitors into lists based on the pages they viewed; the advertiser then uploaded creative, chose an audience, set a budget and CPM bid, and launched a campaign. Perfect Audience purchased impressions through ad exchanges and served ads when tagged visitors appeared on Facebook or participating sites.
The platform spanned Facebook Exchange (FBX), Google's DoubleClick Ad Exchange, Twitter, and other exchanges and networks, with reach described as more than 100,000 websites including Google, Microsoft, OpenX, PubMatic, and Rubicon Project inventory. Its dashboard reported click-through rates, sales, and ad spend, and users could create retargeting lists and conversion goals immediately on signup. Later additions included a reporting API for agencies and larger customers (2013), Perfect Product Retargeting connecting Google Merchant feeds to dynamic Facebook ads (2014), and a one-click Shopify product-feed integration (2019, post-acquisition). Named customers included American Apparel, bebe, Eventbrite, New Relic, 99designs, and Rackspace.
Founding story
Founder Brad Flora trained as a journalist at Northwestern's Medill School and, after graduating in 2008, started the Chicago news site The Windy Citizen and an advertising company, NowSpots, both partly funded by the Knight Foundation, which awarded $250,000 to the real-time ads project in 2010. NowSpots converted a local business's social and blog updates into live display ads and was accepted into Y Combinator's Summer 2011 batch, but newspaper publishers proved unwilling to sell the format. Flora partnered with developer Jordi Buller (referred to as Jordan Buller in contemporaneous coverage), and after asking other YC founders what they would buy from an ad platform, the team pivoted to retargeting — a service they had already been running manually for hundreds of advertisers — and launched the self-service Perfect Audience product in October 2012 after Facebook opened Facebook Exchange to approved partners.
Business model
Software-as-a-service, self-service advertising platform with no setup fees, no maintenance fees, no managed-service requirement, no minimum campaign spend, and no contract. The company stated it charged only when it served an advertiser's ad, retaining a small percentage of media spend; published CPM pricing was roughly $0.25-$0.75 for Facebook retargeting and $1.50-$2.50 for web retargeting.
Revenue derived from a margin on advertising impressions served through the platform, priced on a transparent CPM basis rather than setup or management fees. One secondary account states the company reached positive cash flow and a multimillion-dollar revenue run rate within months of launch; a third-party estimate places revenue in the $1M-$4M range.
Traction
Reported thousands of advertisers, billions of monthly impressions, positive cash flow, and a multimillion-dollar revenue run rate within months of the October 2012 launch, including 2,500 advertisers and 4 billion monthly impressions as of March 2013. Headcount grew from four employees at the start of 2013 to nine by July 2013 and 14 at the time of the June 2014 acquisition; YC lists team size as 11.
Latest developments
Following the June 2014 Marin Software acquisition, Perfect Audience was integrated into Marin's Audience Marketing Suite in September 2014 and continued to ship product updates such as a one-click Shopify product-feed integration in March 2019. Marin sold the business to SharpSpring for approximately $4.6 million in November 2019, and Constant Contact completed its acquisition of SharpSpring in September 2021. One aggregator lists the entity's status as inactive, while another lists it as a subsidiary of Marin Software.
▸Full profile — market position, technology, go-to-market, geography, history, risks & controversies
Market position
Positioned as an accessible alternative to enterprise retargeting vendors and agency-managed services, competing on self-service setup, no contracts or minimums, and transparent CPM pricing. Early access to Facebook Exchange, which was initially restricted to approved partners, provided a distribution advantage; one retrospective source notes that advantage narrowed as Facebook, Google, and other platforms built native self-service retargeting.
No managed-service requirement, no minimum campaign spend, no contract, and no setup or maintenance fees; campaign setup in minutes from a single tracking tag; transparent CPM-based pricing said to be lower than competitors; and combined reach across Facebook Exchange and open-web exchanges from one vendor.
Technology
A JavaScript site tag placed an anonymous browser cookie and segmented visitors into retargeting lists by pages viewed. Campaign management, creative upload, budget and CPM bid setting, conversion-goal tracking, and reporting were handled in a web dashboard; media was bought programmatically through Facebook Exchange, Google's DoubleClick Ad Exchange, Twitter, and networks such as OpenX, PubMatic, and Rubicon Project. Later features included a reporting API, dynamic product ads driven by Google Merchant feeds, and a Shopify feed integration.
Go-to-market
Self-service online signup with a free-trial spend credit and low minimum spend, supported by the company's own advertising bought through its platform, a two-sided referral program sharing revenue with referrers, and a public relations and thought-leadership program aimed at business, ad-tech, and vertical-industry influencers. The company was also hiring engineering, product, and sales staff in 2013 to expand into larger businesses and agencies.
SaaS companies, online retailers and e-commerce brands, small and mid-sized web businesses, startups, and digital agencies — advertisers with modest budgets that previously could not access agency-grade retargeting. Named customers included American Apparel, bebe, Eventbrite, New Relic, 99designs, and Rackspace.
Geography
Headquartered in San Francisco, California, United States; the platform served advertisers buying inventory across web, Facebook, and Twitter, including international publishers such as The Guardian.
History
Sources give inconsistent founding years: Y Combinator lists the company in its Summer 2011 batch, one profile and a 2013 founder pitch give 2011, while Marin Software's acquisition release and other directories state 2012 (the year the retargeting product launched). The self-service platform launched in October 2012 alongside disclosure of about $1.1 million in seed funding. By March 2013 the company reported 2,500 advertisers and 4 billion monthly impressions and shipped a reporting API; in March 2014 it launched Perfect Product Retargeting. Marin Software acquired the company on June 2, 2014 for $22.8 million plus $2.7 million in retention grants, folding it into Marin's Audience Marketing Suite in September 2014. Marin subsequently sold the business to SharpSpring for approximately $4.6 million in November 2019, and Constant Contact completed its acquisition of SharpSpring in September 2021.
Risks & controversies
Retrospective commentary notes that the company's early advantage rested on privileged access to Facebook Exchange rather than proprietary data or workflow depth; once Facebook, Google, and other platform owners offered native self-service retargeting, a third-party dashboard's differentiation eroded. The predecessor product, NowSpots, failed commercially because newspaper publishers would not sell the format. The business subsequently changed hands at a materially lower valuation ($4.6 million in 2019 versus $22.8 million in 2014). Source records also conflict on founding year (2011 vs. 2012), headcount (9, 11, or 14), the founder's first name (Jordi vs. Jordan Buller), and whether a third founder (Kurt Mackey) was involved.
