Good afternoon, everyone. I'm James Reinhart, CEO and Co-Founder of Thredup. Thank you for joining ThredUp's First Quarter 2024 Earnings Call. We are pleased to share ThredUp's financial results for Q1 and have important news to share about how we expect our business financials to improve in the back half of the year. We will provide an update on adjusted EBITDA margin expansion, expectations for free cash flow in 2024 and key company-specific initiatives around AI that we are excited to announce today for the first time. I will then hand it over to Sean Sobers, our Chief Financial Officer, to talk through our first quarter 2024 financials in more detail and provide our outlook for the second quarter of 2024 and the remainder of the year. We'll close out today's call with a question-and-answer session. Let me start with our Q1 results, which were in line with our expectations despite an ongoing difficult consumer backdrop. Our revenue was $79.6 million, representing a year-over-year increase of 5%. Consolidated gross margin came in at 69.5%, representing 8% gross profit growth year-over-year. Recall we believe gross profit growth is the best way to measure the underlying growth in our business due to our continued transition to consignment, especially in Europe. U.S. gross margins reached a record high of 80.1%. Active buyers reached $1.7 million, increasing 4% year-over-year, while orders reached $1.7 million, growing 9% compared to the same time period last year. Of note, adjusted EBITDA totaled negative $736,000, or minus 0.9% of revenue, due to ongoing leverage in our business as well as some reorganizing that we did in March. Our U.S. business was adjusted EBITDA positive for the third quarter in a row and was free cash flow positive for the quarter. Now let me turn to the future, as we have important context to share about how our business is transforming into an AI-powered resell company and what the year ahead will look like. In March, we reduced headcount and reorganized several parts of the business, enabling us to invest more in AI product development, boost processing in our distribution centers and increase marketing spend. We cut approximately $13 million in operating expenses and reinvested roughly half of those savings into high potential growth areas. The result of these changes is that we expect to achieve positive adjusted EBITDA in Q2, nearly triple our full year adjusted EBITDA results compared to our last outlook, and to generate free cash flow on a full year basis in 2024. We have now pulled forward our free cash flow expectations by a full year. We view this to be an important milestone for the company as we turn the page from answering questions about profitability to focusing on how we expect to invest earnings over time and growing our business to capture the long-term opportunity in resale. With that in mind, let me turn to the progress we've made across our product investments that are improving the customer experience and planting new seeds for sustainable long-term growth. In just the last 60 days, we have launched a new AI search experience and created 2 new AI-powered tools that allow consumers to thrift any style that inspires them. These tools make ThredUp the easiest place to thrift, no matter when the inspiration strikes, whether that's from the high street, when they see their favorite outfits, when shopping online at any of their favorite stores, or even if they want to tell us about an event that they're shopping for and have us do the work to inspire them. All 3 of these features are now live in beta form. You can try the new visual search in our search bar, and you can visit our ThredUp concept store on your smartphone at thredup.com/concept to see the other new tools in action. The competitive advantages that we have been talking about for many years, our supply chain infrastructure, proprietary data and marketplace dynamics, are now being amplified by AI technology breakthroughs that have only recently started to take shape. I want to emphasize my belief that AI strengthens the advantages we already have in place and deepens the long-term defensibility in our business. With our business expected to generate free cash flow this year, we remain ever committed to investing in new vectors of opportunity to grow our business faster with an eye towards creating stronger long-term earnings, and this goes beyond just AI. In Europe, the transition to consignment continues, and we are making progress across our key strategic areas. Of note, we set new records in Q1 for the number of bag requests in a week, the number of bags returned in a week and the number of consignment bags processed in a week. We processed more consignment bags in Q1 than we did in all of 2023 combined. After concluding our write-off at the end of 2023, we believe our assortment strategy is paying off. Our sell-through rates are among the strongest they have been since we acquired Remix in late 2021. We also announced last week that we have hired Florin Filote as our GM of Europe. He is relocating to our European headquarters in Sofia, Bulgaria. Florin brings 2 decades of experience building and scaling marketplaces, and we believe he is absolutely the right person to continue scaling top line revenue and driving margin expansion in Europe. He will run our EU business while sitting on our U.S.-based executive team. I'm also just as excited that Dan DeMeyere, who previously was running our EU business while being based in the U.S., will return to the U.S. business as Chief Product and Technology Officer as we scale all of our tech and AI products. Next, we've continued to scale our Resale-as-a-Service, or RaaS, business. In Q1, we added 8 new brands to our client roster, and you can now get a ThredUp co-branded cleanout kit in 800 retail stores across the country. And with some clients, we've begun natively integrating the ability to order a cleanout kit right from their e-commerce checkout page. We are also looking to expand our RaaS footprint in Europe and believe commercial agreements with brands and retailers there can further accelerate our transition to consignment. Now let me turn to our impact. As we remain committed to balancing purpose and profits, it's also worth noting how we're driving impacts beyond our core business. We recently started to see our advocacy efforts take shape at the federal level. As a founding member of the American Circular Textiles Coalition, we helped advocate for the inclusion of $14 [ billion ] of incentive for textile circularity in the Americas Act, a bipartisan trade bill that was introduced by U.S. Senators, Bill Cassidy and Michael Bennet in March. This is a historic moment as it's the first time federal legislation has contemplated circular fashion. We believe recognizing circularity potential to strengthen the U.S. economy from both an environmental and international trade perspective is a huge step forward for the industry. Until fashion is no longer one of the most damaging sectors of the global economy, we will continue to advocate for the government to provide resources that make fashion and textile industries more sustainable and planet-friendly. In conclusion, before I turn it over to Sean, I want to emphasize a few milestones and guiding principles. We think about our earnings this quarter being a reestablishment of who we are and where we're headed along these 4 dimensions. First, over the past 2 years, including the midpoint of our 2024 guidance, we have expanded adjusted EBITDA 1,800 basis points and now expect free cash flow on a full year basis in 2024. Second, while driving adjusted EBITDA margin expansion, we have not compromised driving growth. At the midpoint of our 2024 guidance, the underlying growth rate of our business over the past 2 years, which is gross profit growth due to the consignment shift, is 24%. This year represents annual double-digit growth despite an ongoing volatile consumer environment. Third, we now have the ability to more rapidly improve the customer experience, especially with emerging AI technology and invest in growth while simultaneously achieving our free cash flow goals. We believe we are in a position to manage the magnitude of growth and profits effectively regardless of where the consumer environment goes. Finally, we want to reestablish the trust of the investment community, that we are great stewards of capital, that our most innovative days are ahead of us and that we do not want to just meet our expectations, we want to exceed them. That is the journey we begin anew today. With that, I will now turn it over to Sean to go through our financial results and guidance in more detail.
