Rob will be stepping down as our CFO by the end of May or earlier depending on when we name his successor. We have initiated a search and expect to name a successor as soon as possible. Rob has been a highly valued team member of Brightcove for more than 12 years and nearly six as our CFO. He has been a great business partner to me and our entire team. On behalf of all of us at Brightcove, I want to thank Rob for all he’s done for the company and also for helping us manage a smooth transition to a new CFO this year. So, with that, I’m going to turn the call over to Rob for a deeper dive on Q4 and the numbers, and I’ll be back for QA.
Rob Noreck: Thank you, Marc, and good afternoon, everyone. I’ll start by saying thank you to Marc, the entire team at Brightcove and the Brightcove Board for an incredible run with the company. As Marc mentioned, I’ll be stepping down in Q2, but I will be here to manage this transition smoothly. I’m incredibly supportive of the management team we have here, and I believe deeply in their ability to execute, all of which makes this the right time to affect this transition. So, with that said, I will begin with a detailed review of our fourth quarter and finish with our outlook for the first quarter and the full year 2024. Total revenue in the fourth quarter was $50.2 million, above the midpoint of our guidance range. Please note that our guidance included approximately $1 million for a live event that was subsequently canceled towards the end of the quarter.
Breaking revenue down further, if we exclude overages of $900,000 in the quarter, revenue was $49.3 million, up 3% year-over-year. Subscription and support revenue, which includes overages, was $47.8 million and professional services revenue was $2.4 million, flat and up 54%, respectively. 12-month backlog, which we define as the aggregate amount of committed subscription revenue related to future performance obligations in the next 12 months, was $127.3 million. This represents a 6% year-over-year increase. Total backlog was $183 million, up 19% year-over-year and our highest total backlog ever. We continue to see success shifting the mix of our new business and renewals towards multiyear contracts. This is positively impacting our total backlog and improving the predictability of the business.
On a geographic basis, we generated 60% of our revenue in North America during the quarter and 40% internationally. Breaking down international revenue a little more, Europe generated 17% of our revenue, and Japan and Asia-Pacific generated 23% of revenue during the quarter. Let me now turn to the supplemental metrics we share on a quarterly basis. Net revenue retention in the quarter was 95% and which compares to 93% in the third quarter of 2023 and 94% in the fourth quarter of 2022. This is largely in line with recent quarters and continues to reflect the impact from the lower add-on sales performance in the year. We expect that as we continue to expand our add-on sales capabilities, make improvements in our renewal business and increase our focus on multiyear deals, this metric will improve over time.
Recurring dollar retention rate in the fourth quarter was 94%. The improvement in recurring dollar retention rate over recent performance was driven by a strong underlying gross retention rate. As we continue our strategic focus on multiyear deals, this metric continues to become less meaningful as it only captures renewals in the quarter and upsells at the time of renewal and does not factor in the impact of multiyear deals. Our customer count at the end of the fourth quarter was 2,559 of which 2,028 were classified as premium customers. Looking at our ARPU within our premium customer base, our annualized revenue per premium customer was $96,200 and excludes our entry-level pricing for starter customers, which averaged $3,900 in annualized revenue.
This is up 8% compared to $89,000 in the fourth quarter of 2022. Looking at our results on a GAAP basis, our gross profit was $30.8 million, operating loss was $2.3 million, and net loss per share was $0.06 for the quarter. Turning to our non-GAAP results. Our non-GAAP gross profit in the fourth quarter was $31.6 million compared to $30.7 million in the year ago period and represented a gross margin of 63% compared to 62% in the year ago period. Non-GAAP operating income was $2.1 million in the fourth quarter compared to non-GAAP operating loss of $1.4 million in the fourth quarter of 2022. Adjusted EBITDA was $5.5 million, representing an adjusted EBITDA margin of 11% and a 366% increase year-over-year and above the midpoint of our guidance range.
This is our second consecutive quarter of double-digit EBITDA margins, driven by the cost savings initiatives we have implemented over the course of the year. Non-GAAP diluted net income per share was $0.04 based on 43.6 million weighted average shares outstanding. This compares to a net loss per share of $0.02 on 42.2 million weighted average shares outstanding in the year-ago period. Looking at our full year 2023 results. Total revenue was $201.2 million compared to $211 million in 2022. Please recall that the majority of this year-over-year decline is related to a decrease in our overage revenue which decreased $7.4 million from $12.2 million in 2022 to $4.8 million in 2023. On a GAAP basis, gross profit was $123.8 million. Operating loss was $21.6 million and net loss per share was $0.53 based on 43.1 million weighted average shares outstanding.
On a non-GAAP basis, gross profit was $127.1 million. Loss from operations was $693,000, adjusted EBITDA was $11.9 million, and net loss per share was $0.04 based on 43.1 million weighted average shares outstanding. Turning to the balance sheet and cash flow. We ended the quarter with cash and cash equivalents of $18.6 million. We generated $4.2 million in cash flow from operations and free cash flow was $1.4 million after taking into account $2.8 million in capital expenditures and capitalized internal use software. I would like to finish by providing our guidance for the first quarter and the full year 2024. For the first quarter, we are targeting revenue of $49 million to $50 million, including approximately $800,000 of overages and approximately $2.4 million of professional services revenue.
