Thank you, Brian, and thanks, everyone, for joining us today. I'm going to spend a few minutes on our results for the second quarter as well as the key trends that we believe are driving those results and then spend a few minutes providing an update on several important positive operational developments in the business. Mark will then walk through our financial results and our outlook for the remainder of the year. During the second quarter, we delivered strong results across every key measure of the business, including revenue, ARR, RPO, subscriptions, gross margins and profitability. Based on the strength of these results, the strong demand drivers we are seeing in our key end markets and the confidence we have in our outlook for the remainder of the year, we are again raising our guidance for 2023. Revenue in the second quarter was $19.8 million, up 119% year-over-year. Our growth continues to reflect strong customer acquisition activity, expanding ARPUs and deal sizes and overall growth in the number of active subscriptions. We welcomed over 70 new customers in the second quarter and activated 600 new multiyear subscriptions of Evolv Express. We now have nearly 3,400 units deployed. Based on our strong subscription growth in the first half of the year and our pipeline for the second half, we think it's likely that we will end the year with close to 4,500 subscriptions compared to our early estimates of 4,000. Our robust growth in customers and subscriptions continue to drive accelerated visitor screening activity during the quarter. We screened over 170 million visitors in the second quarter, more than double our screening activity in the year ago period. We're now averaging nearly 1.9 million visitors screened a day, up from 900,000 visitors in the second quarter of last year. We have now screened over 750 million visitors and are on pace to reach 1 billion within visitors screened before the end of the year. Our customers use Evolv Express to detect over 179,000 weapons in the first half of 2023, which is more than we were tagged our customers all of last year. More scanning and detection data means our systems get smarter and more accurate over time. We grew ARR from $42 million at the end of Q1 to $54 million at the end of Q2, reflecting growth of about 30% sequentially and 160% year-over-year, again, fueled by increased subscriptions and the accelerating shift to reoccurring revenue. We remain well positioned to more than double our ARR in 2023. This growth, coupled with continued gross margin expansion, and prudent expense management, gives us confidence in our ability to deliver adjusted EBITDA ahead of our earlier targets. Mark will share more thoughts about this and those results of our upwardly revised outlook in the moments ahead. Our strong results continue to reflect several powerful growth trends. We continue to see broad adoption of our AI-based solutions with strong end market demand in education, health care and professional sports. The education market, which represents about 60% of our business in the second quarter grew by nearly 50% sequentially. Our solutions are now being used to screen about 250,000 students every single day, a tenfold increase from just a year ago. We added nearly three dozen new education customers in the second quarter. We can now be found in 14 of the top 100 school districts in the country. We're pleased to welcome the Prince William County School District in Virginia, the San Antonio Independent School District in Texas, the Northwest India [ph] Lighthouse Charter Schools, Nova Southeastern University in Florida, the Westminster Public School in Colorado, the Providence St. Mel School in Chicago, the NASH County Public Schools in North Carolina and the Jackson Public Schools in Mississippi. We continue to exceed our early leadership position in the health care market, which includes over 6,000 hospitals and where over 70% and of workplace violence takes place. We added0 another 15 new health care customers in the second quarter, including the ChristianaCare Health System, which is comprised of three hospitals throughout the Northern Delaware system, Sanford Health with operations throughout both North and South Dakota and the Singing River Health System on the Mississippi Gulf Coast. We saw a 50% sequential increase in activity in our health care business in Q2. We are now screening over 300,000 hospital visitors every single day compared to just 20,000 a year ago. Professional sports remained a high-visibility vertical for us. Some of our most recent wins in the market include Mercedes-Benz arena in Berlin, Germany, and our 12th National Football League franchise to Houston Texans. We're proud to now partner with over 40 professional teams across the National Football League, Major League Baseball, the National Hockey League, Major League Soccer. We screened close to 20 million fans across professional sports in the second quarter, a nearly 3x increase year-over-year. We expect to be screening close to 1 million football fans on any given Sunday this fall when the 2023 NFL season kicks off. We continue to see accelerating momentum with our channel partners. About 70% of our bookings activity in the second quarter came through the channel. We continue to work very effectively with dozens of channel partners, including Alliance Technology, which is a particularly strong partner in the education vertical. Johnson Controls, Motorola, STANLEY Securitas, Stone Security, Allied University, ICU technologies and many others. We're pleased to host the first ever Evolv Technology Partner Summit in the second quarter. The collaboration event was attended by over 100 executives and sales and technical personnel from across our partner ecosystem and was a great opportunity to align on go-to-market strategies, product innovation and technical training. Another important trend that we saw throughout the second quarter was the increased adoption of our subscription model about 75% of all unit bookings in the second quarter were via our pure subscription model. That was directly correlated to the gross margin expansion, we delivered in Q2. Finally, we continue to see growing deal sizes. In fact, our average deal size was up about 20% year-over-year reflecting both higher selling prices per unit and an increase in the average number of units per deal. I want to briefly highlight some important developments during the second quarter on the product innovation and partnership front. First, starting with product innovation. We're absolutely delighted to announce the general availability of Evolv Express 6.0. This is the latest upgrade of our Cortex AI software platform that we released in the second quarter. We believe it offers several key technical breakthroughs. First, we're now able to offer our customers a new higher sensitivity threat level, which provides enhanced detection of some smaller bladed weapons. While we have long provided exceptional detection capabilities with guns and bombs and larger tactical knives, 6.0 is designed to extend our detection capabilities, with respect to smaller bladed weapons. Interestingly, knife tagging by our customers was up 39% sequentially and 25% year-over-year in the second quarter. This surge, in bladed weapon tagging is significantly faster than our growth in subscriptions and in new customers. Another important breakthrough with 6.0 is that it enables our customers to reconfigure more easily evolve Express units, which our customers say is important in tight lobby spaces like schools and in hospitals. Customers can now change the system's physical configuration and the software will automatically adapt to it. So we're making it even easier for our customers to deploy our technology without sacrificing detection capability. Like all our releases, 6.0 is available to our customers as an upgrade delivered to an ongoing subscription. This is both an expectation and a benefit of being a SaaS company. We don't merely drop off the sensor platform, but we can efficiently deliver more value and features to our customers over the four-year subscription contracts with software enhancements. Turning to two important partner developments. I want to take a moment to update investors on our work with Ricoh and with Columbia Technology. We're delighted with our new partnership with Ricoh, one of the largest service delivery organizations in the world. Our new support and service partnership expands our customer service program by leveraging Ricoh's well-established and comprehensive Service Advantage program. We believe this will extend our own coverage and provide better, faster service for our rapidly growing customer base. The Ricoh partnership is designed to provide our customers with increased field service resources, expanded technical support and an expedited part availability. The partnership will provide an increased workforce of highly trained field engineers, eventually including about 250, Ricoh technicians located throughout the United States. We believe this will provide faster enablement of resources to customers for break/fix and preventative maintenance services. We're also now able to augment our own staff resources with third-party technical engineers, who can provide meaningful first response Level 1 technical support from the moment the first phone call comes in. Finally, in the coming months, we expect to expand the number of locations around the country where parts are stored enabling even faster delivery. Another important milestone for us in the second quarter was our expanded partnership with Columbia Technology. Columbia Technology, which has been our long-time contract manufacturer, is now an authorized distributor of Evolv Express. Simply put, customers that prefer to purchase the hardware component of Evolv's Express can now do so by placing an order with one of the -- one of our approved reseller partners which in-turn will place a hardware order for Evolv Express directly with Columbia Tech under, a separate reseller agreement. So customers don't have to turn to Evolv, to purchase the hardware component of their Evolv Express System. Concurrently, the approved reseller, partner will place a second order with us for a long-term Software Subscription contract, which will power the newly purchased Evolv Express. The complete solution will be distributed by Columbia Technology. This is an important expansion of our strong partnership and is designed to make it even easier for our customers to procure and deploy, Evolv Express directly from our manufacturer. We believe this expanded partnership will ensure that we can fully support the contractual preferences of our customers, particularly those with grant Resources or accustomed to working under a CapEx model. We believe this expanded partnership with Columbia Technology and our new partnership with Ricoh are two important steps, in supporting our long-range plans to cost effectively develop into a $1 billion ARR business. So before I turn things over to Mark, let me briefly summarize. We're reporting solid second quarter results, highlighted by strong growth in revenues, ARR and RPO. We again delivered strong growth in both the new customer acquisition and in expanding deployments within our existing customer base. We saw a significant improvement in gross margins, reflecting accelerated adoption of our pure, subscription model. We continue to see evidence of the leverage in our business model as revenue growth again, outpaced operating expense growth. We expect to execute well, on our growth plans for 2023 and which is focused on doubling our ARR, and we believe that the strength of our balance sheet will enable us to reach cash breakeven without the need to raise any additional capital. With that, let me turn things over to Mark, who will take you through our financial results and our outlook. Mark?
