Dominic Phillips: Thank you, Sanjit. Q3 was highlighted by several new records for important operating metrics and surpassing notable milestones. First, we surpassed $1 billion of ARR and just our eighth year of selling to customers. Second, this was our third consecutive quarter of accelerating year-over-year net new ARR growth at a larger scale. Third, we achieved a quarterly record number of large customer additions with both 100k plus and 1 million plus ARR customers. Fourth, our video-based safety and vehicle telematics products each surpassed $400 million of ARR while still growing more than 30% year-over-year. And lastly, we achieved our first quarter of positive non-GAAP operating profit led by a quarterly record non-GAAP gross margin.
Q3 was another quarter of sustained high growth at scale. Our ending ARR was $1.003 billion, growing 39% year-over-year, and Q3 revenue was $238 million, growing 40% year-over-year. Several factors drove our strong topline performance in Q3. First, we continue to focus on serving large enterprise customers to drive durable and efficient growth at scale. We now have 1,663, 100k plus ARR customers, a quarterly record increase of 148, representing 49% year-over-year growth. We also saw particular strength within our largest customers. We now have 71 $1 million plus ARR customers, a quarterly record increase of nine, representing 54% year-over-year growth accelerating from 51% year-over-year growth last quarter at a larger scale. 100k plus ARR customers also represent our fastest-growing cohort and make up 51% of our total ARR up from 47% one-year ago.
And our land-and-expand strategy for large customers continues to pay off. In Q3, four of our five largest net new ACV transactions were new logos, including three new $1 million plus ARR customers that each landed with our three largest products, Video-Based Safety, Vehicle Telematics and Equipment Monitoring. Additionally, almost 60% of the 100k plus ARR customer additions in Q3 were expansions to existing customers, allowing us to achieve our target dollar-based net retention rate of 115% and 120% for core and large customers respectively. Second, our customers increasingly utilize Samsara as a system of record for physical operations by subscribing to multiple applications all on one unified platform. More than 90% of our large customers and 75% of our core customers subscribe to multiple application licenses.
As a result, our two vehicle-based applications, video-based safety and vehicle telematics, each represent more than $400 million of ARR and our largest non-vehicle-based application equipment monitoring, which is used to locate and manage field assets, is more than $100 million of ARR. In addition to large scale, each of these product categories is growing more than 30% year-over-year. Additionally, our largest transactions increasingly include multiple products. In Q3, nine of our top 10 net new ACV deals included two or more applications. Our largest new logo in Q3 a leading U.S. aggregates company with over 1,000 on and off-road vehicles and over 6,000 field assets across more than 500 locations landed with video-based safety, vehicle telematics and equipment monitoring.
Partnering with Samsara, the customer is eliminating more than 50,000 hours of manual reporting and data input work, gaining insight into equipment utilization, providing safety coaching, and saving millions of dollars on annual fuel spend. Third, we continued to demonstrate strong execution in several frontier markets. Most notably, 17% of net new ACV came from international geographies tied for our strongest quarter ever, driven by strength in Mexico and Europe. Additionally, our construction and public sector verticals each contributed their highest net new ACV mix over the last three years, led by new customers such as the City of New Orleans, serving nearly 400,000 residents and millions of visitors annually. This large municipality landed with video-based safety, vehicle telematics and equipment monitoring across 41 city departments, including Police, Fire, Public Works, Code Enforcement, Parks and Parkways, Sanitation, and more to proactively manage maintenance, improve operational efficiency and safety, and increase asset utilization.
And lastly, we saw strength in emerging products that provide additional expansion opportunities within our existing customer base. Mobile Experience Management or MEM is a new software-only product that allows customers to manage mobile devices in the field through features such as end-to-end visibility, remote access, and display customization. Q3 was our first full quarter selling MEM, and we’ve already crossed $1 million of ARR. In addition to driving strong topline growth, we continued to deliver operating efficiency improvements across our business as we scale. Non-GAAP gross margin was 75% in Q3, a quarterly record and approximately 2 percentage points higher year-over-year, driven largely by optimizing cloud, cellular and support costs.
Non-GAAP operating margin was positive for the first time at 5% compared to negative 10% in Q3 last year, an improvement of approximately 15 percentage points year-over-year. And adjusted free cash flow margin was 4% or $9 million in Q3 compared to negative 9% or negative $15 million in Q3 last year, an improvement of 12 percentage points or $23 million year-over-year primarily from improved operating leverage and continued working capital improvements. Okay, now turning to guidance. Based on our Q3 results and increased forecast visibility for the last quarter of the fiscal year, we are raising our revenue and profitability guidance both in dollars and margin. For FY2024, we are raising our revenue guidance to between $918 million and $920 million or 41% year-over-year growth.
As a reminder, our fiscal year always ends on the Saturday closest to February 1st, which means every six years, our fiscal year calendar includes 53 weeks instead of 52. As such, FY2024 includes an extra week in Q4, resulting in 14 weeks instead of our typical 13-week quarter. We expect the additional week will add approximately 3 percentage points of year-over-year growth in FY2024, which was factored into our prior guidance as well as the updated guidance provided today. Additionally, we don’t expect this will have a material impact on FY2024 ARR because sales quotas are consistently set regardless of the number of days or weeks in a fiscal quarter or a year. Similarly, we don’t expect a material impact on our key profitability metrics because additional expenses will be required to support the additional revenue.
