The 5 Best Team Chat Apps for Businesses in 2025

Finding the perfect team chat app for your business feels like dating in the digital age – you've got options galore, but most of them leave you wondering "is this really the one?" Whether you're building a scrappy startup or managing a Fortune 500 enterprise, the right communication platform can make the difference between a team that moves mountains and one that can't even agree on lunch orders.Let's face it: email is about as modern as sending smoke signals, and WhatsApp is great for sharing memes with your college friends, but not so much for managing quarterly projections. Your business needs something more sophisticated – something that can handle everything from quick "where's the coffee?" messages to complex project coordination.In this comprehensive guide, we'll dive deep into the 5 best team chat apps for business in 2025, helping you navigate the crowded landscape of business communication tools to find your perfect match. Think of this as your wingman in the world of workplace collaboration.

Remember when business communication relied solely on scattered emails or personal messaging apps? Those days are thankfully behind us. Here's why dedicated team chat apps have become essential for modern businesses:

Communication Efficiency That Actually Works

Team chat apps help businesses improve response times, reduce confusion, and strengthen teamwork across different departments or locations. Unlike email threads that spiral into confusion faster than a group text about dinner plans, team chat apps organize conversations logically and keep everyone on the same page.

Real-Time Collaboration Without the Chaos

Modern teams don't work in silos. Whether you're coordinating a product launch or troubleshooting a client issue, implementing a team chat is a great way to streamline your business communication and promote collaboration and transparency between your staff. It's like having a virtual office where everyone can pop in and out of conversations as needed.

Remote Work Revolution Requirements

With hybrid and remote work becoming the norm, these apps are especially important for mobile, remote, or deskless teams who need real-time access to conversations and company updates. Your team chat app becomes your digital headquarters – the place where culture, collaboration, and productivity converge.

Not all chat apps are created equal. Here's what separates the champions from the wannabes:

Essential Features Checklist

• Instant messaging with threaded conversations

• Group channels for different teams and projects

• File sharing capabilities (because nobody likes email attachments anymore)

• Video and audio calling for when typing just won't cut it

• Mobile apps that actually work well

• Search functionality to find that important message from three months ago

• Integration capabilities with your existing business tools

• Security features to keep your conversations private

Pricing That Makes Sense

Compare the pricing plans of different team chat apps and consider your budget. Some apps offer free versions with limited features, while others may have subscription-based plans with more advanced functionalities. The key is finding the sweet spot between features and cost that works for your team size and needs.

User Experience That Doesn't Require a PhD

A team chat app that is easy to use and navigate ensures quick adoption and seamless communication among team members. If your team needs a week-long training course to send a message, you've chosen the wrong app.

1. Slack - The OG That Still Delivers

Slack is the premier traditional team chat application, with a history of strong focus on the user experience. Widely popular chat features pioneered by Slack include emoji reactions (2015) and emoji user statuses (2017).Why Slack Rocks:

• Intuitive Interface: Users generally feel that Slack has the best UI among traditional team chat apps

• Integration Paradise: Slack ties in with more than 800 different app integrations

• Familiar Territory: Slack's popularity makes team onboarding easier, because many people have used it before

Pricing Breakdown:

• Free Plan: 90-day access to message history, 10 app integrations, 1:1 audio/video meetings, and 1:1 messages with people outside your organization

• Pro Plan: $8.75/month allowing for unlimited message history, group video meetings, outside organization groups, and unlimited integrations

• Business+: $15/month with all the previous features along with message export for compliance, provisioning, and increase in storage

Perfect For: Established teams that need extensive integrations and don't mind paying premium prices for premium features.

The Reality Check: The free plan can be limiting, and the paid plans are expensive compared to other team chat apps. But if budget isn't your primary concern, Slack delivers exceptional value.

2. Microsoft Teams - The Corporate Giant's Answer

Teams is the most commonly used business chat app, in large part due to Microsoft's anti-competitive strategy of bundling Teams with the Office 365 suite. But beyond the controversial bundling, Teams has evolved into a legitimate powerhouse.Why Teams Wins:

• Office 365 Integration: Teams come with deep integration of the Office 365 apps, giving you full access to create, edit, format Word, Excel, PowerPoint, and other Office 365 applications

• Meeting Powerhouse: Microsoft Teams allows hosting meetings with up to 100 attendees in its free version, which upgrades to 250+ participants when using a paid plan

• Value Proposition: Comparing the pricing plans, Microsoft Teams offers more storage for similar pricing. In addition, Microsoft Teams is already included in the business and enterprise subscriptions. If your company is already subscribed to Microsoft 365, you can use the premium version of Teams without incurring additional costs

Pricing Structure:

• Free Version: Limited channels, meetings, and storage of 5 GB while still allowing for unlimited chat, file sharing, collaboration, and data encryption

• Paid Plans: Bundled with Microsoft 365 subscriptions

Perfect For: Organizations already invested in the Microsoft ecosystem who want seamless integration across all their productivity tools.

The Honest Truth: It's been built to check the standard procurement department checkboxes, not to provide an excellent user experience. We've talked to hundreds of Teams users, and they almost universally have feelings somewhere on the "dislike it" to "hate it" spectrum. However, for many organizations, the integration benefits outweigh the UX concerns.

3. Discord - The Dark Horse for Business

Yes, you read that right. While Discord shines for casual use, it's not built with business in mind, but hear us out – this gaming-focused platform has some surprising business advantages.

Why Discord Deserves Your Attention:

• Superior Voice Quality: It can be set up to become virtual meeting rooms where you can immediately chat with people in your server

• Free Forever: Discord is and has always been free, in contrast with Team which is a paid app, and Meets, which is free for now. Another thing going for it is the fact that it's a true freeware solution

• Video Capacity: Discord supports 25 ongoing video calls (more than Microsoft Team's 20, but shy of Google Meet's 250)

The Business Reality Check: Discord works best for creative teams, tech companies, or businesses with a more casual culture. If you deal with extremely sensitive data, no. You'll need to explore Microsoft Teams (or even, Skype), which come with robust true end-to-end encryption. This ensures sensitive talking points (corporate or trade secrets, or other confidential information) are only seen by the intended recipient. While Discord does encrypt information, it is decrypted in Discord servers, and not truly at the "end" recipient.

Perfect For: Creative agencies, gaming companies, tech startups, and teams that prioritize voice communication and don't handle sensitive data.

4. Google Chat - The Workspace Integrator

Google Chat is a rather minimalist messaging app that helps your team stay connected and work easily. Because it's integrated with Google Workspace, it works with other Google applications like Gmail, Calendar, and Drive, making it a great choice for companies with an already well-established Google base.

Google Chat's Strengths:

• Seamless Integration: Perfect if you live in Google Workspace

• Simple Design: The interface of this application has a simple and intuitive layout that allows any team to dive into their conversations straight away without any redundancy. Besides that, it is prepared for small and huge teams; regardless of the size of your company, Google Chat can answer your communications

• Mobility: Always stay connected, anywhere, anytime, with Google Chat on mobile, web, and desktop. On mobile, the app lets you send messages, share files, and collaborate on the go. Web and desktop versions open up a larger interface for more comfortable conversations and team management

The Trade-Off: Compared to Slack or Pebb, Google Chat can feel bare-bones. It's functional but not feature-rich, making it ideal for teams that prefer simplicity over sophisticated functionality.

Perfect For: Teams whose requirements are light, no-frills communication, with some collaborative featuresand who are already heavily invested in Google Workspace.

5. Chanty - The Budget-Friendly Powerhouse

Chanty is a straightforward team messaging app that sets itself apart by emphasizing task-oriented communication. Rather than just serving as a general chat tool, Chanty organizes conversations around specific tasks, making it a good choice for teams with clearly defined objectives and workflows.

Why Chanty Stands Out:

• Affordable Excellence: Chanty's paid plan to be competitively priced, making it an attractive option for teams seeking value without sacrificing core features

• Task Integration: AI-powered team chat with built-in task management features. Unlimited message history in the free plan for easy access. Intuitive and user-friendly interface for smooth onboarding

• Unlimited History: Unlimited message history in free plan

The Limitations: Chanty's integration with third-party apps could be more robust. While it works well for teams looking for a simple, cost-effective communication tool with a focus on tasks, its limited app integrations may be a drawback for teams relying on other productivity tools.

Perfect For: Teams with a structured workflow that need a lightweight communication tool to keep everyone on track, especially smaller businesses and startups watching their budgets.

The ROI of Better Communication

Think better communication is just a "nice to have"? Think again. A 2025 Workplace Trends Survey reported that 44% of employees consider "transparent and easy communication" a top reason to stay at their current job. In other words, your chat app choice could literally affect your retention rates.

Productivity Gains That Actually Matter

When your team can collaborate effectively, magic happens. Projects move faster, fewer things fall through the cracks, and everyone spends less time in unnecessary meetings. It's like giving your entire organization a productivity superpower.

Integration with Your Business Ecosystem

Speaking of productivity, if you're running B2B outreach campaigns or managing complex sales processes, your communication tool should play nicely with your other business apps. For example, teams using platforms like Emelia.io for their cold email and LinkedIn outreach campaigns benefit tremendously when their chat app can integrate with their sales and marketing stack, keeping all team communication and campaign coordination in one seamless workflow.

Small Teams (Under 10 People)

For smaller teams, focus on simplicity and cost-effectiveness. Chanty or Google Chat often provide the best value without overwhelming your team with features they don't need.

Medium Teams (10-50 People)

You're in the sweet spot for most platforms. Slack offers the best balance of features and usability, while Microsoft Teams makes sense if you're already in the Microsoft ecosystem.

Large Enterprises (50+ People)

Microsoft Teams typically wins for large organizations due to enterprise features, security, and cost-effectiveness at scale. However, Slack remains popular for companies prioritizing user experience and extensive integrations.

Remote-First Companies

Prioritize platforms with excellent mobile apps and video calling capabilities.

Discord surprisingly excels here for creative teams, while Microsoft Teams dominates for traditional businesses.

Start Small, Scale Smart

Don't try to migrate your entire communication infrastructure overnight. Start with one team or department, learn what works, then expand gradually.

Establish Communication Guidelines

Create clear rules about when to use chat versus email versus video calls. This prevents your team chat from becoming just another noise source.

Leverage Integrations Wisely

Connect your chat app to the tools you use most frequently, but don't go overboard. Too many integrations can create notification fatigue faster than you can say "productivity boost."

AI Integration is Coming Fast

Microsoft Copilot creates better meeting and IT administration experiences than Slack's AI, which is limited in scope and functionality. Expect AI assistants to become standard features across all platforms.

Security Will Become Even More Important

As remote work continues, expect enhanced security features and compliance capabilities to become table stakes for business chat apps.

Voice and Video Will Rule

Text is great, but voice and video communication will become increasingly important as teams look for more human connection in digital workspaces.

What's the most popular team chat app for business?

Microsoft Teams has 320 million active monthly users, while Slack has 65 million, making Teams the most widely used platform primarily due to its bundling with Office 365.

Are free team chat apps good enough for business?

Many free plans offer excellent value for small teams. Chanty provides unlimited message history for free, while Discord offers robust voice communication at no cost. However, larger teams typically need paid features for advanced security and administration.

Can team chat apps replace email entirely?

Not entirely, but they can significantly reduce email volume. Team chats excel at real-time collaboration and quick updates, while email remains better for formal communication, external contacts, and documentation.

How secure are team chat apps?

Security varies significantly. Microsoft Teams and Slack offer enterprise-grade security, while Discord provides basic encryption but isn't suitable for sensitive business data. Always review security features based on your industry requirements.

What's the best team chat app for remote teams?

Microsoft Teams and Slack both excel for remote work, offering comprehensive video calling, screen sharing, and collaboration features. Discord can work well for creative teams that prioritize voice communication.

How do team chat apps integrate with other business tools?

Integration capabilities vary widely. Slack leads with 800+ integrations, Microsoft Teams integrates seamlessly with Office 365, and Google Chat works perfectly with Google Workspace. Consider your existing tool stack when choosing.
