GroupMe

GroupMe is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand GroupMe rather than just read about it. In short: GroupMe (also stylized as groupme) is a mobile group messaging app owned by Microsoft. It was launched in May 2010 by the private company GroupMe.

Key takeaways

GroupMe belongs to computer science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect GroupMe to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of GroupMe from memory before moving on to harder problems.

Reference excerpt

GroupMe (also stylized as groupme) is a mobile group messaging app owned by Microsoft. It was launched in May 2010 by the private company GroupMe. In August 2011, GroupMe delivered over 100 million messages each month and by June 2012, that number jumped to 550 million. In 2013, GroupMe had over 12 million registered users. In March 2024, reports noted that while Microsoft had discontinued development of Skype for consumers, it continued to actively support GroupMe. The app received recent updates and was highlighted as a messaging platform still maintained by Microsoft, contrasting with the declining attention given to Skype.

History

Grouply, the app that would become GroupMe, was created in May 2010, at a hackathon at the TechCrunch Disrupt conference. Its creators, Jared Hecht and Steve Martocci intended the app to replace email chains as a method of communication. After investors took notice of the app, Hecht and Martocci took a loan from Hecht's parents and began working on their app full-time. The name was changed to GroupMe in August. The same month, GroupMe raised $85,000 from investors. The app was released on the App Store in October 2010. In January 2011, GroupMe received US$10.6 million in venture capital from Khosla Ventures, General Catalyst Partners, angel investors, and others. In August 2011, Skype acquired the one-year-old start-up for around $80 million. Skype had itself been purchased by Microsoft in May 2011, with the purchase finalized in October 2011. The app underwent a redesign in late 2012. Initially, groups were limited to 100 members, but a support request could get a group's limit raised as high as necessary as it approached the limit. In 2019, GroupMe stopped offering group member limit increases; however, the app increased the standard limit from 100 to 5000. Following Skype's downfall and subsequent shutdown, GroupMe would not shut down but rather be moved under the Microsoft AI division and will be integrated with services such as Microsoft Copilot.

Usage GroupMe works by downloading the app or accessing the service online, and then creating an account by providing your name, cell phone number, and password, or connecting through a Facebook or Twitter account. The service then syncs with your contacts and from that point forward the user can make groups, limited to 5000 members. An individual who is part of an active group has the ability to turn off notifications for the app; users will still receive the message, but will not be notified about it. Each group is given a label and assigned a unique number. Some of the features of the app include the ability to share photos, videos, locations, create events, and emojis from various packs. GroupMe has a web client as well as apps for iOS, Android, Windows Phone, and Windows 10. GroupMe messages can be received and sent through SMS (available only in the United States). Users begin by creating a “group” and adding contacts. When someone sends a message, everyone in the group can see and respond to it. The app allows users to attach and send pictures, documents, videos, and web links. Users can also send private messages, but only to users who are also active on the GroupMe app.

GroupMe has been studied as a communication tool in higher education settings. Research has explored its use for facilitating course-related discussions, supporting collaboration in small groups, and supplementing classroom learning in both online and face-to-face contexts. Another study examined how platforms like GroupMe can support literacy learning by encouraging communication in multiple modes, including text and images, framing this form of digital discourse as a legitimate academic genre.

Worked examples

Example 1 — a first encounter with GroupMe

Start with the simplest possible case. Write down what GroupMe claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to GroupMe before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about GroupMe ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of GroupMe

In research: GroupMe appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses GroupMe in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: GroupMe is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2011 mergers and acquisitions, American companies established in 2010, Android (operating system) software, so understanding it makes those chapters shorter.
In everyday life: Look for GroupMe outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is GroupMe in simple terms?

GroupMe (also stylized as groupme) is a mobile group messaging app owned by Microsoft. It was launched in May 2010 by the private company GroupMe.

Why does GroupMe matter?

Because it connects several computer science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study GroupMe?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
