importantly, we are a major player in the consumer distribution of U.S. insurance, as each month, EverQuote gets more website consumer visits than all of the largest of the U.S. insurers and EverQuote connects insurance providers with more than $3 million quote requests each quarter.
We have built a deep provider network with over 160 of the 1,500 largest insurance carriers operating in the U.S. including the top 20 P&C companies, and since we recognize the value of the agency channel for consumers, we have 7,500 agents participating in our marketplace as well. Over the past eight years, we have driven substantial revenue growth and have grown to over 250 great employees, including more than 150 data scientists, analysts and engineers whose collective talent, when leveraged with our accumulating data, proprietary technology and market breadth, represents our most critical assets. We have grown a lot and we’re proud of what we’ve accomplished and of our great team but we are still in the early days and as we look forward, see substantial growth built to come. We expect our growth to continue for three main reasons: network effect, opportunities to drive further penetration of our current market and the powerful long term secular trends we see driving a shift from offline to online in insurance.
First, as a leading insurance marketplace, EverQuote benefits from a number of network effects, from growing data distribution and technology advantages in many aspects of our business and, as in any network-driven business, we think these will drive growth and margin over time. For example, our success in improving customer acquisition and customer matching are both fundamentally driven by data and the breadth and scale of our many data assets is a substantial and growing competitive advantage.
Over the last eight years, we’ve accumulated data from over 131 billion ad impressions, served 40 million consumer quote requests derived from over $440 million of online market spend. As our data assets grow, our algorithms for bidding and consumer alignment become more powerful and sophisticated, improving our value for consumers and providers.
In addition, our success as a marketplace and value to consumers also depends on the breadth of our provider network. Again, today we work with more than a 160 participating insurance carriers and over 7,500 local insurance agents and we are focused on continually expanding our provider coverage. The breadth of our provider network allows us to provide multiple relevant matches to consumers and we believe is a substantial competitive advantage and it also allows us to offer a strong consumer value proposition.
The second reason we expect growth to continue is that we believe EverQuote can drive greater penetration of insurers’ online advertising budgets as we grow and optimize our business. While we are already the largest online marketplace for insurance shopping in the U.S., we plan to drive greater penetration in the insurance market with a variety of internal and external initiatives of scale. In particular, we continuously invest in data, product, provider distribution and new verticals with the goal of driving greater traffic, improving consumer engagement and outcomes, all while pursuing data-driven optimization to improve the economics of our provider partners.
For example, we plan to attract more consumers to our marketplace. We believe there is substantially more consumer traffic to capture by expanding on existing sources, exploring new channels such as online video, and across new verticals. We also expect, over time, greater brand awareness of EverQuote as our algorithmic performance advertising continues to scale. In addition to attracting more consumers, we’ve built a dedicated engineering team to accelerate provider integration to drive improved performance for consumers and providers and this team added 13 new or expanded integrations in the second quarter. Further, in distribution, we continued to add new providers and during the second quarter we had 15 new carrier partners across auto, home and life. With hundreds of remaining carriers and tens of thousands of remaining agents still not yet participating in our marketplace and plenty of room to grow with the providers who are already on the platform, we believe we have substantial room to expand by adding new provider partners.
