- Microsoft Teams had 320 million monthly active users in 2024, way beyond 65 million monthly and 42 million daily active users of Slack.
- By 2025, Slack was projected to reach $4.22 billion in revenues worldwide, whereas Microsoft Teams surpassed the $8 billion mark in 2023, jumping from $6.8 billion in 2020.
- Microsoft Teams revenue grew rapidly early on, from $10 million in 2017 to $800 million in 2019 and $7.7 billion in 2021, quite outpacing Slack’s steadier growth graph.
- In 2023, Slack had about 32.2 million daily active users (DAUs) and was forecasted to see this number jump to 38.8 million in 2024, while Teams maintained at a massive 320 million DAUs.
- Monthly active users of Slack increased from 43.1 million in 2022 to 54.1 million in 2023 and will become 79 million in 2025; the daily engagement being so high with Teams indirectly envisages a much larger MAU base.
- Slack has a focus on startups and SMBs, registering 63,035 users from companies making $1–10 million annually, whereas Teams has a stronger enterprise presence but does not give any revenue-delineated user figures.
- Slack is much more popular amongst younger users, especially those in the 25 to 34 age group (33.29%); Teams has a stronger presence among users who fall into the 35 to 44 (31.23%) and 45 to 54 (29.98%) age groups.

- The GP Bullhound report Slack vs Microsoft Teams statistics predicts that Slack will generate $4.22 billion in revenue worldwide by 2025, embellished with a higher estimation due to the growth trajectory of the digital communication and collaboration industries. This estimation translates the continued upward trend of Slack in revenues, which proves the phenomenon of demand in remote and hybrid working environments.
- The revenue increases year by year, driven by the momentum of widespread user adoption for team communication.
- Meanwhile, compared to Teams by Microsoft, the revenue growth has been much steeper and faster ever since Teams came into existence in 2017.
- It was just $10 million for the first year, but it quickly breached $200 million in 2018 and grew to $800 million in 2019.
- Then the pandemic hit in 2020, and it exploded the revenue as the platform for remote work solutions.
- Now it is almost $8 billion with an estimated revenue of $7.7 billion in 2021 and reached $8 billion plus in 2023, which has cemented its place in the top ranks.
- Because of the integration with Microsoft 365 and enterprise acceptance during and after the pandemic, Microsoft Teams has generated revenues in leaps and bounds than Slack. Slack, on the other hand, uses an approach that emphasises the usability of its platforms, innovation, and adoption by agile teams and mid-sized organisations.

- According to a Statista report, Slack vs Microsoft Teams statistics state that in 2023, Slack gained another big leap in daily active users, going from 25.7 million in 2022 to about 32.2 million, while Microsoft Teams recorded about 320 million daily active users, which is significantly higher throughout the entire year.
- The user growth of Slack will continue, with daily active users being anticipated to rise to 38.8 million in 2024 and to 47.2 million by the end of 2025, whereas Microsoft Teams has already saturated the market at a far larger scale.

- In contrast, whereas Microsoft Teams’ MAU figures are never broken out, their tremendously high daily usage speaks of a strong engagement base from corporate adoption and integration with Microsoft 365.
- The rapid rise in Slack’s user base exhibits growing worldwide interest from businesses and organisations toward more flexible and integration-rich teaming tools.
- Alongside this, the huge dominance of Teams is attributed to its inclusion inside Microsoft 365 and the fact that it was the go-to application for teamwork during the Coronavirus pandemic, which saw daily home internet data usage in the USA jump by 4.4 GB, almost a 40% increase compared to March 2019.
- This overall trend gave a boost to the growth of platforms, such as Teams, when demand increased for video conferencing, messaging, and collaboration across devices, stretching from smartphones to gaming consoles.
- While Slack is steadily growing, gaining favour among smaller teams and startups, Microsoft Teams remains the strongest in the enterprise communication domain, courtesy of its early scaling during the pandemic and bundling of its product.

- Revenue-wise, user distribution is not disclosed by Microsoft Teams, but given its stronger appeal to the enterprise and public sectors, there may be a concentration of large-scale or institutional users. While overall, it seems Slack is dominated by startups, tech, and marketing firms, Microsoft Teams dominates larger enterprises, education, government, and private health sectors.

FAQ.
Microsoft Teams considerably outclasses Slack in terms of users, having had 320 million MAUs in 2024, whereas Slack is estimated to have 65 million MAUs and 42 million DAUs. The user superiority of Teams comes mainly from the integration with Microsoft 365 and large enterprise adoption.
Microsoft Teams leads in revenue, generating over $8 billion in 2023, up from $6.8 billion in 2020. In contrast, Slack is projected to reach $4.22 billion in global revenue by 2025, showing steady but slower growth. The fact that Teams is bundled with Microsoft 365 accelerated its financial dominance alongside its early pandemic adoption.
IT service, education, healthcare, and government are all led by Microsoft Teams. Slack, conversely, takes marketing and advertising (7%), internet/tech startups, and, at least in terms of small to mid-sized enterprises, perhaps the strongest user base there.
Slack is popular primarily with young professionals: 33.29% of users are between 25 and 34 years old, and there is a balanced gender split. On the other hand, Microsoft Teams tends to draw an older crowd of the 35-54 category, with more than 61% of its users falling therein, and 20.82% belong to the age group of 55 and above, being too industry-oriented.
While rubbing shoulders with 129 million Asian-Pacific downloads alone in the second quarter of 2020 and 8.6 million in the Middle East & Africa, Microsoft Teams very well takes the crown for the highest global downloads, witnessing deep levels of implementation throughout enterprises. In contrast, Slack recorded 900,000 downloads in February 2023 (600,000 for iOS and 400,000 for Android) and crossed the 10-million mark for total Android downloads.
