All right. Thank you, Fionna, and welcome, everyone, to our earnings call. This is the first quarter in 2020 that was impact-free from the COVID situation in China as COVID-19 gradually fade off between late May and early June. But even without the short-term demand caused by COVID in China, we still delivered another quarter of outstanding results with revenue of USD 30.8 million for the third quarter, an increase of 81% year-over-year.
Our number of registered applications reached more than 240,000 at end of September, adding nearly 10,000 per month in Q3. Our number of active users reached more than 1,800, up 95% year-over-year. Outside of China, we continue to see strong demand for our real-time voice and video products in both mature use cases such as entertainment and gaming and emerging use cases such as education and virtual demand.
We also made solid progresses in our products, brand and ecosystem in this quarter. In particular, I'm proud of our marketing and design team who created an amazing experience at our RTE2020 Virtual Conference with more than 8,000 registered attendees, and tens of thousands of unregistered viewers, 170 guest speakers and over 100 companies all over the world participated.
We also had our first RTE start-up challenge with more than 130 start-ups joining the competition. More than 75% of these start-ups are already founded, and 50 of them were selected to join our start-up program, where they will receive premium platform usage credit and dedicated technical support. At Agora, we constantly support start-ups at early stage to cultivate innovation and accelerate the emergence of new use cases for RTE technology. At RTE2020, the discussions will focus not only with exists -- not only with what exists today but how to reimagine model simulation or innovative RTE application and build the future together.
The traditional concept of communication is all about the exchange of information, but creating a successful real-time engagement use cases requires a lot more than that. It is about creating a shared moment and space for people to begin and interact with the user. We focus our attention on the 3 pillars of real-time engagement: shared context, interactivity at any scale and ubiquity. To create shared context, the offer is more than just video and voice but also use case specific core such as signaling, virtual events -- virtual environment, augmented reality objects, content moderation, voice recognition and so on. We can't do all of these ourselves so we have partnered with leading third-party service providers.
Now many of those features can be easily used by developers as part in a smaller platform. Our plan is to make Agora platform the engine for developing any real-time engagement application. Shared context also depends on having smooth, lax, and [ zero-fee ] experiences that simulate real life. That is why we are rolling out our experience level agreement, or XLA. With XLA, Agora will not only let you know what the number of minutes you are running on are of premium quality, but we will also guarantee our performance on the 4 core metrics that are critical to any of your experiences. Channel join successful rate, audio fluency, video fluency and transmission latency.
Since its launch, we have signed up dozens of well-known Internet companies for XLA. Of course, fully immersive experience should be available for any size of talent, which brings us to the second pillar of real-time engagement, interactivity at any scale.
Since the very beginning, we have designed our platform to be highly scalable. For example, recently, we supported an education customer in South Asia, with more than 50,000 concurrent video users in one fully interactive classroom.
At Agora, we feel real-time engagement should be available anywhere to anyone and in any app. So that brings us to our third pillar, ubiquity. For this to become reality, we have been making our technology broadly available and easy to adopt. We are committed to supporting all popular operating systems, browsers and development frameworks.
Earlier this year, we add React Native and Flutter SDK to our list of supported SDKs. In this quarter, we also released our Unreal SDK for gaming and RTOS SDK for IoT devices, which will release more space for RTE use cases to grow.
As we discussed in the past, we have seen sterling entrepreneurs who have some great ideas but lack the time, resources to build an app from scratch. So we want to make it even easier for anyone to create their own RTE apps. For this reason, we launched the Agora Education Application PaaS and Agora RTE App Builder. With Agora Education aPaaS, you can create an online education application with very limited coding, whether it's one-on-one classroom, small class or interactive large class with massive number of attendees.
Agora's RTE App Builder was even a step further. Whether you are a CEO, Director or a product manager, you can now create a product-ready -- or production-ready conference app with no coding at all in a matter of minutes, and you can then customize the design and specify the specification of the app in many ways based on your unique requirements.
Last but not the least, security, compliance and privacy protection are critical to our success. In this quarter, we made steady progresses in enhancing our operational standards such as best practice in software development, data access and management and end-to-end encryption. Recently, we were awarded 3 ISO certificates on our information security management system, which further attest to our rigorous security practice and strengthens the trust developers have in Agora.
Now let me turn this over to Jingbo, who will review our financial results.
