Yottaa, the Boston-based startup which aims to speed up website performance, netted $9 million in Series B funding from initial investors General Catalyst Partners, Stata Venture Partners and Cambridge West Ventures as well as some new-but-unnamed backers. That brings total venture funding to $13 million for the two-year-old company.
Yottaa, which offers both website performance optimization and security services, targets both small-and-medium businesses (SMBs) and large enterprises. SMBs often don’t do a lot to speed up their website performance simply because many of the available solutions — from Cisco(s csco) or F5 Networks — are too pricey or difficult to implement, according to Yottaa CEO Coach Wei. “In SMBs, we compete with ‘do nothing,'” Wei said in an interview Monday.
In enterprises, it faces off against traditional content delivery networks (CDNs) from Akamai(s akam) and Limelight. As GigaOM reported last spring, Yottaa uses third-party clouds, including Amazon Web Services (s amzn) to deliver its optimization services.
The new funding will help the company — which already claims good customer momentum — build more. Since Yottaa’s Site Speed Optimizer launched in October, 2011, the company’s site has drawn 100 million unique visitors. Some 80,000 web sites have used Yottaa’s services to date, Wei said. Under the company’s freemium model — site monitoring is free but optimization and security services are not . Yottaa does not disclose how many customers are paying.
