Thank you, Greg. We had a solid quarter and ended the year considering the current macro backdrop. Total fourth quarter revenue increased 22% year-over-year to $165 million and for the full year, revenue increased 22% to $629 million, both of which were within our guidance range, including the negative impact of FX. Since nearly 60% of our revenue is from outside of the US, the year-over-year increase in total revenue includes a negative impact of 4 percentage points from changes in FX rates in both Q4 and the full year. We also exceeded the high end of our Q4 and full year 2022 adjusted EBITDA margin guidance ranges as we continue to focus on operational efficiencies and driving towards profitability. Q4 revenue growth was driven by the strength of Udemy Business. The segment accounted for 50% of total full year revenue for the first time, well ahead of the goal we set at the time of our IPO. That being said, we did experience some elongating sales cycles, pushing some deals into Q1. At the same time, the consumer marketplace remains healthy. Although segment revenue was down year-over-year in Q4, driven by the negative impact of FX, Udemy's marketplace continues to produce a steady source of organic leads and serves as a powerful content creation engine that provides fresh, high quality courses that ultimately feed the Udemy's business content library. As we move down the P&L, note that all financial metrics are non-GAAP unless stated otherwise. I will keep my remarks focused on the fourth quarter results. Our news release, which can be found in our Investor Relations Web site, includes the financial tables with results for the three and 12 month periods ended December 31, 2022. Q4 gross profit was $94 million, up 29% year-over-year. Gross margin was 57%, a 320 basis point improvement from Q4 of 2021, driven by the continued revenue mix shift to Udemy Business since content cost as a percent of revenue are lower for that segment. Total operating expense was $119 million or 72% of revenue compared to 75% in Q4 of last year as we continue to focus on driving company wide operational efficiency. Within OpEx, sales and marketing expenses were 47% of total revenue compared to 50% for the same quarter last year. We typically experienced some seasonality during the fourth quarter when we ramp up our marketing investments around Black Friday. Due to the current macroeconomic environment, we reduced spend on consumer marketing this year in order to maintain a reasonable ROI and also shifted the balance of spend toward Udemy Business where we see greater long term growth potential. R&D expense was 14% of revenue compared to 12% in Q4 2021. We are investing in areas that we believe support learner outcomes and increase ROI such as immersive learning modalities, business skills, AI and machine learning. And finally, G&A expense was 11% of revenue versus 13% a year ago. On the bottom line, net loss in the quarter was $23 million or negative 14% of revenue. Adjusted EBITDA loss was $20 million or negative 12% of revenue, well ahead of our guidance range of negative 17% to negative 15%, driven by our continued focus on efficient expense management. Moving on to key cash flow and balance sheet items. We ended the year with $465 million of unrestricted cash, cash equivalents and marketable securities. Increasing DSO changes in working capital timing and a onetime payment to settle our instructor withholding tax reserve resulted in a negative $34 million in free cash flow for Q4. Now turning to our results by segment, starting with our Enterprise segment or Udemy Business. We grew Q4 revenue to $91 million or an increase of 57% year-over-year, which includes a negative 4 percentage point impact from changes in FX rates. Segment gross profit for the quarter was $60 million or 67% of segment revenue, roughly flat year-over-year. Annual recurring revenue was $372 million at the end of Q4, up 55% year-over-year. We saw a bit of a deceleration in ARR growth, primarily due to the reasons Greg outlined earlier but ended the quarter with nearly 14,000 Udemy's business customers, up 32% from a year ago. We continue to see strong adoption and retention across all geographies, particularly with larger companies, but that is being somewhat offset by softness in smaller businesses and elongating sales cycles. In many cases, we are landing with meaningfully higher deal sizes and contract lengths and continue to gain traction with our newer products, Udemy Business Pro and cohort learning. Those trends impacted our customer retention, resulting in Q4 Udemy's business net dollar retention rate of 115%, or a 200 basis point decrease from the prior quarter. However, net dollar retention for our Udemy's business large customers or those with at least 1,000 employees was 123%, which was flat with the prior quarter. Not only are we seeing solid retention of our existing customers but those larger customers are looking for the most efficient solutions to partner with to achieve their long term company wide learning and development goals, which is driving an increase in seat expansion and contract lengths. Turning to our Consumer segment. Although Q4 revenue was $75 million or down 4% year-over-year, that includes a negative 5 percentage point impact from FX. Taking the FX impact into consideration, it is encouraging to see the continued resilience of our marketplace even in this challenging environment. Segment gross profit was $37 million or 50% of segment revenue, approximately 240 basis points higher than in Q4 2021. The year-over-year expansion in Consumer segment gross margin was primarily driven by the timing of revenue recognition relative to instructor payments. Our marketplace continues to be vibrant and healthy. During Q4, our platform saw nearly 35 million monthly average unique global visitors, up 6% year-over-year and more than 1.3 million monthly average buyers purchased a course of subscription, down approximately 2% year-over-year on meaningfully lower consumer marketing spend. Now I'd like to introduce our outlook for the next quarter and full year 2023. We are cautiously optimistic about 2023 as we balance the momentum we are seeing in our main growth engine with the macro uncertainty. Many of the positive trends that we experienced at the end of 2022 are expected to continue this year, including a shift from offline to online learning and vendor consolidation. We believe that growth maybe somewhat offset, especially in the near term by smaller corporations reducing their learning and development budgets and companies in all geographies closely evaluating vendors, which may translate into sales cycle elongation across the board. We also expect our Consumer segment revenue to decrease slightly year-over-year due to the FX impact and shifting our spend to the Udemy Business growth engine. For modeling purposes, while we do not plan to provide segment guidance going forward, we wanted to share some high level insight on our anticipated Udemy Business and consumer segment quarterly patterns with our outlook, so you can better understand how we're thinking about the respective businesses. With all that in mind, we expect Q1 revenue to be between $168 million and $172 million, with Udemy's business segment revenue as a percentage of total revenue remaining relatively flat with the prior quarter due to our Q4 2022 consumer promotion cycle and revenue recognition. Assuming foreign currency exchange rates remain constant, FX is expected to negatively impact Q1 year-over-year total revenue growth by approximately 6 percentage points. For Udemy Business, while we expect Q1 year-over-year growth to moderate as compared to Q4, we believe a year-over-year growth rate in the mid 40s is achievable. For the rest of the year, while Udemy Business’ growth may slow a bit, we believe that we can sustain mid 30s year-over-year growth each quarter, including the negative effect of FX and continued macroeconomic pressure. By year end, we anticipate Udemy Business revenue will grow to approximately 60% of total revenue. Turning to Consumer. We expect segment revenue to be up slightly in Q1 compared to Q4. However, we anticipate consumer revenue to be down low double digits year-over-year on a percentage basis in Q1, including the impact of FX. Similar to last year, we expect consumer revenue to be down sequentially in Q2 as a result of our most significant promotions occurring around year end, which benefits Q1 due to the timing of revenue recognition. We expect growth rates to improve in the back half of the year due in part to the easing of the impact from FX headwinds. Taking all of that into consideration, for the full year 2023, we expect revenue to be between $700 million and $730 million or 14% year-over-year growth at the midpoint, including an estimated 3 percentage point negative impact from FX. And finally, for adjusted EBITDA margin, excluding severance costs, we expect Q1 margin of negative 10% to negative 8%. We expect to deliver adjusted EBITDA margin expansion each quarter on a sequential basis, with the most significant increase from Q1 to Q2, driven by the cost savings associated with the reduction in workforce. As I mentioned earlier, we expect to be profitable on an adjusted EBITDA basis for the second half of the year, with Q3 expected to be near breakeven and Q4 to be positive. As a result, we expect full year 2023 margin to be between negative 4% and negative 2%. At the midpoint, this implies nearly 500 basis point adjusted EBITDA margin expansion for the full year. Importantly, we remain confident in our ability to deliver full year profitability on an adjusted EBITDA basis in 2024. As Greg said at the outset, we are cautiously optimistic about 2023 and the opportunity ahead. The trends we are seeing today, particularly in our Udemy Business segments, are very encouraging for the long term. We will continue to make strategic investments in areas of the business that represent the greatest long term growth opportunities while committing to continued cost discipline in order to deliver a profitable second half of the year. And with that, we'll open up the call for your questions. Moderator?
