Thank you, Brian. Let's turn to our fourth quarter and full year financial results and our guidance for the first quarter and full year of 2019. Q4 was a very strong quarter for HubSpot. We delivered strong revenue growth, over $25 million of free cash flow and $14 million of non-GAAP operating profit. Fourth quarter revenue grew 35% year-over-year on an as reported basis and 37% in constant currency, up nearly two points from Q3 2018 constant currency revenue growth. The sequential increase in the quarter is the result of continued traction from our 2018 product launches and strong install base [ph] sales. Q4 subscription revenues grew 35% year-over-year as reported, while services revenue grew 49% year-over-year. Services revenue growth in Q4 benefited from a mix shift towards our professional and enterprise SKUs and an uptick in classroom training. While we're pleased with this overall performance, keep in mind that services revenue represents a small percentage of our overall revenue, and we expect services revenue to grow more slowly than subscription revenue in 2019. Full year 2018 revenue grew 37% as reported and 35% in constant currency. As Brian discussed, we had a really strong year of revenue growth overall in 2018 driven by several factors, including strong lead generation, new product releases and a seasoned sales force that executed very well. HubSpot ended 2018 with 56,628 total customers, which was up 36% year-over-year. Average subscription revenue per customer in Q4 was $10,012, down 2.4% year-over-year and up slightly compared to Q3. While we are encouraged by the sequential increase, we continue to expect this metric to bounce around depending on product mix and the amount of new versus installed base selling in any quarter. International performance also continued to be strong in Q4, with international revenue growth of 48% year-over-year on an as-reported basis and 52% in constant currency. Domestic revenue growth reaccelerated in Q4 to 28%, up two points from Q3. International revenue represented 38% of total revenue in Q4, up three points from last year. During 2018, we opened a new office in Bogotá and announced plans to open an office in Paris later this year. We continue to see lots of opportunity for more growth outside the United States. Deferred revenue as of the end of December was $185.5 million, a 33% increase year-over-year. While calculated billings, defined as revenue plus the change in deferred revenue, was $166.9 million, up 33% year-over-year. Currency movements within the quarter resulted in a headwind to calculated billings, which grew 35% in constant currency, up one point compared to Q3 constant currency billings growth. The remainder of my comments will refer to non-GAAP measures. Fourth quarter gross margin was 82.3%, up slightly sequentially and up one point year-over-year. Subscription gross margin was 86.5%, flat sequentially, while services gross margin was 2.5%, up nearly 16 points sequentially and up 20 points year-over-year. Full year gross margin was 81.6%, up nearly one point compared to 2017. Fourth quarter operating margin was 9.8%, up 5.8 and 5.4 points from Q3 and Q4 of last year, respectively. Full year operating margin was 6.3%, up four points versus 2017. As we've talked about in prior quarters, the adoption of ASC 606 had a positive impact on operating margin for the year because we extended the period of time over which we recognized commissions expense. This contributed three points of margin expansion to our 2018 results, while the underlying business delivered one point of leverage. We continue to drive operating leverage in the business that is consistent with our long-term framework for growth and profitability. And we remain committed to the framework going forward. At the end of the fourth quarter, we had 2,638 employees, up 27% year-over-year. Attrition remained favorable throughout 2018, which positions us well to execute on our 2019 growth plan. CapEx, including capitalized software development costs, was $8.1 million in the quarter and $33.5 million for the full year. Moving on to earnings. Net income in the fourth quarter was $15.8 million or $0.37 per diluted share. Full year net income was $36.9 million or $0.89 per diluted share. With that, let's dive into guidance for the first quarter of 2019. Total revenue is expected to be in the range of $146.5 million to $147.5 million. Non-GAAP operating income is expected to be between $9.5 million and $10.5 million. Non-GAAP diluted net income per share is expected to be between $0.23 to $0.25. This assumes approximately 44.4 million fully diluted shares outstanding. And for the full year of 2019, total revenue is expected to be in the range of $648 million to $652 million. Non-GAAP operating profit is expected to be between $46 million to $50 million. Non-GAAP diluted net income per share is expected to be between $1.08 and $1.16. This assumes approximately 45.6 million fully diluted shares outstanding. We expect full year free cash flow to be about $60 million. As you adjust your models, keep in mind the following: Currency movements created a four point positive impact on reported revenue growth in both Q1 and Q2 of 2018, was roughly neutral in Q3 and was a headwind of a little more than one point in Q4. Given the volatility and FX rates throughout 2018, we thought it would be helpful to provide some additional context for how FX will impact our as-reported growth rates in 2019. At current spot rates, we're forecasting foreign exchange headwind of approximately $8 million to as-reported 2019 revenue, which would equate to a 1- to 2-point negative impact to as-reported growth. Substantially, all of these currency impacts will occur in the first two quarters of the year. Our 2019 guidance implies two points of normal course operating margin improvement, offset by one point of margin pressure from the amortization of sales commission's expense under ASC 606. This will result in one point of operating margin improvement on an as-reported basis. Furthermore, we expect to realize the majority of our operating leverage in the first and fourth quarters. CapEx as a percentage of revenue for 2018 was 6.5%, which is a couple of points below our historic average. We expect CapEx as a percentage of revenue to return to 8% in 2019, primarily as a result of the build-out of our new Dublin facility. To close, 2018 was an especially strong year of operational and financial performance, and we believe we are well positioned to build on this momentum in 2019. With that, I'll hand the call back over to Brian for his closing remarks.
