Instart Logic, provider of a cloud-based service for web publishers that dramatically improves web user experience even over mobile and WiFi networks, today announced a $17 million Series B funding round. This brings total funding to $26 million, which includes investments from Andreessen Horowitz, Greylock Partners, Sutter Hill Ventures and Tenaya Capital, with additional investments from Silicon Valley leaders.

"Today's web and mobile users expect near instant delivery of applications, but the explosion of apps combined with the proliferation of mobile devices has resulted in debilitating performance issues that degrade the user experience," said Peter Levine, partner at Andreessen Horowitz. "Enter Instart Logic, which has developed a unique and elegant solution that was built from the ground up to resolve the mobile bottleneck and transform the user experience."

"This is a breakthrough technology that will disrupt the market," said Brian Melton, partner at Tenaya Capital who led the firm's investment in the Series B round. "Early customers of Instart Logic reported dramatic results."

Instart Logic's service solves the problem of deteriorating web application performance and diminishing user engagement driven by two technology trends. On one hand, web applications continue to grow in size and complexity, as static web sites are supplanted by immersive, interactive applications. On the other hand, more and more people access these web applications over increasingly congested networks, resulting in poor user experiences.

"Yesterday's solutions for speeding up delivery of web and applications are showing their age, as they addressed core network congestion but not the last mile," said Dr. Peter Danzig, who formerly served as a vice president at Akamai and was an early investor in Riverbed. "By approaching this problem thinking mobile first, Instart Logic was able to develop a sophisticated solution."

Built by a team of experts with diverse experience across big data analytics, large-scale web application infrastructure, virtualization and networking, Instart Logic's service deploys entirely new technology to allow users to start interacting with rich Web applications dramatically faster than legacy solutions. Reducing the time-to-engagement improves the user experience significantly, making immersive web applications stickier and more profitable for publishers.

Instart Logic's founding executive team -- Manav Mital, Hariharan Kolam and Raghu Venkat -- came from the engineering group at Aster Data, the big data analytics company acquired in 2011 for $263 million by Teradata Corporation. Instart Logic's team bring years of experience from Google, Facebook, Amazon, VMware, Citrix, Akamai, Adobe, and Mozilla.

Instart Logic successfully completed its beta program in December 2012. The vast majority of beta customers -- including a Fortune 500 company -- are now using the service in production for mission-critical applications. These paying customers use Instart Logic's service to drive conversions and increase user engagement across a broad set of industries including retail, travel and hospitality, enterprise SaaS, online gaming, and media -- sectors where immersive and interactive experiences are essential.

Instart Logic invites Web publishers to participate in its limited availability program by registering here http://www.instartlogic.com. The product will be generally available later this year.
