Have you wondered how some of the best-known startups have scaled up so efficiently? There is a pretty good answer to this question, and it’s generally through Lean Methodology. Companies that have embraced this methodology worldwide have given rise to a whole new way for entrepreneurs to scale their businesses early in their development.

Whether through customer feedback, constant experimentation, or continuous development of core products, Lean Startup methodologies allow a business to grow without sacrificing talent or time. Perhaps most importantly, we have seen this in action through several companies that have incorporated Lean practices and are now among the biggest brand names in the world.

1. Instagram

Originally founded as “Burbn,” Instagram began as a mobile check-in app in 2010 by Kevin Systrom and Mike Krieger. As Instagram started its pivot, it used Lean Methodologies to become a photo-sharing platform and has since become the most notable photo-specific site across the social media landscape. 

As a result of its pivot, Instagram gained 1 million users within the first two months and another 10 million in its first year. This would lead Facebook to acquire the company for $1 billion in 2012, having already achieved 30 million users. 

Fast-forward to 2025, Instagram now claims over 2 billion monthly active users and remains one of the world’s most dominant social media platforms. This is a clear demonstration of the power of lean pivoting and a customer-driven focus. 

As Burbn was Instagram’s initial MVP, the company was heavily focused on combining the popularity of check-in functionality alongside gamification and photo-sharing. The company was resource-strapped initially and only launched to a few early adopters. Thanks to the Instagram team’s early focus on gathering user feedback and data, it wasn’t focused on building too many unnecessary features. 

Instagram’s founders, Systrom and Krieger, were heavily engaged with users and believed in maintaining direct communication. Through this communication, they learned that photo-sharing, especially with built-in filters, was easily the app’s most popular and engaging feature. The feedback from users also reminded them that check-in and gamification features weren’t as important. This led the founders to create a feedback loop to help them prioritize photo-sharing and drop the two other core features of the app. 

Relaunching Instagram and focusing on photo-sharing was the future. This pivot required the company to remove any other non-core features and rebuild the app in just eight weeks. 

By focusing on upload speeds, simplifying the interface to be photo-specific, and introducing new photo filters, the app developers were quickly addressing customer pain points. The biggest takeaway is that Instagram’s team learned that users wanted a photo-heavy, mobile-first app through lean methodologies. 

Slack

One of the foremost communication apps in the workspace and a staple of small and large businesses around the globe, Slack needs little introduction. Founded in 2013 by Stewart Butterfield, it might surprise many people to learn that Slack was originally a gaming startup known as Glitch. 

Receiving early angel funding, the company released its first computer game, which sold poorly, leading to the company “unlaunch” the game, and it never returned to store shelves again. At this moment, the company pivoted to “Slack” as a “real-time collaboration app.” 

Ultimately, Slack’s pivot was a wild success as the company grew to 2 million daily active users by 2016 and 12 million by 2019. After being acquired in 2020 for $27.7 billion, more than 750,000 organizations rely on Slack for internal communication across different business functions.  

During the development of Glitch, the future Slack team built an internal chat tool to better coordinate their work on the game. Just by happenstance, with the game failing and customer feedback poor, the company had this incredible opportunity to pivot and focus on the chat app, becoming the MVP. Best of all, the app had already been tested internally with a small group of other startups. 

Early beta testers of the Slack platform were able to provide feedback through analytical details, interviews with the Slack team, and surveys. The Slack team learned people wanted more search functionality and a mobile app. During this process, one of Slack’s best features, integrating with third-party services like Google Drive, came to life. 

Thankfully, Glitch’s failure led the team to focus on the chat app, simplifying and beautifying its interface for a larger group of users. Based on user feedback, the company also added features and integrations with tools like Google Drive, Dropbox, and GitHub. The company also did a great job with A/B testing to help users better organize the many channels they subscribed to, so it best met the demands of launching in large markets. 

Zappos

Founded in 1999, Zappos quickly pioneered the online shoe industry by incorporating lean principles that went on to build one of the most customer-centric brands still in business today. Zappos is legendary for its customer service, and I can personally speak from experience when I needed shoes for my wedding, Zappos overnighted them to me without a charge, permanently winning my loyalty. 

Launching the company with future CEO Tony Hsieh, Nick Swinmurn wanted the site to adopt a business model similar to drop shipping. Swinmurn went directly to local shoe stores, took pictures of the shoes, and then launched them on the site using this photography. When someone wanted to purchase the shoes, Swinmurn would go to a store, buy them, and then ship them for a small upcharge.

Zappos has since been sold to Amazon but remains one of the world’s most prominent online shoe businesses. Its lean approach allowed it to minimize risk and solidify a business model while learning that customer service was its key differentiator. 

With Swinmurn photographing inventory, posting listings, and buying shoes at retail pricing, Zappos’ current business model wasn’t very profitable. However, it was a fantastic opportunity to test whether there was both demand and a shipping model that could work to scale the business. It allowed Zappos to grow without holding inventory or requiring extensive infrastructure like a warehouse. 

In the initial stages of Zappos, the company was gathering customer feedback through order patterns and inquiries about the available products. This allowed the brand to learn about its customers’ likes and the most common sizes it needed. Swinmurn also contacted customers directly to understand their troubles when ordering shoes. He also realized that free shipping and easy returns were key to growing a loyal customer base. 

With a core model taking shape, Zappos had to pivot by introducing an unheard-of 365-day return policy. This policy would help reassure customers during the early days after the dot-com bust that buying online was safe. The company also tested free two-way shipping, another customer need that many retailers were not addressing. These learnings helped transform Zappos into a leading customer-focused and service-driven retailer. 

Dropbox

Arguably, one of the most famous examples of a company using Lean Methodology to scale to a billion-dollar brand is none other than that of Dropbox. Founded in 2007 by Drew Houston and Arash Ferdowsi, Dropbox is known today as a cloud-based file storage and synchronization service. 

In April 2025, Dropbox was valued at more than $8.30 billion. Since then, it has become one of the leading names in its space and competes directly with industry titans like Microsoft, Apple, and Google over file storage. With over 700 million registered users and 18.16 million paying users, Dropbox boasts users in 180 countries. 

Creating a three-minute demo for the brand as Dropbox’s MVP, Drew Houston developed a sizzle reel showing how seamlessly Dropbox could handle file sync across any number of devices. The video was shared on Hacker News, targeting early adopters of new services. This low-cost MVP tested whether there was any demand for such a product from a company other than Microsoft or Google. 

With thousands of beta testers from the Hacker News video, user feedback came in quickly and instantly. Between forums, emails, and surveys, Dropbox was almost overwhelmed by the user feedback it received. Here, the company learned about customers’ desperation for a reliable product that could work cross-platform while allowing for easy use. A continuous feedback loop continues today as the company looks to evolve its product to meet user demand. 

Early versions of Dropbox focused heavily on creating a user interface that was not complex and could easily be navigated with any number of files uploaded. The team used a Build-Measure-Learn cycle to continue testing new features, eventually introducing popular features like version history and shared folders, which were tested with beta groups before being widely rolled out. 

Other Useful Tools and Concepts

After this detailed reading on Lean Methodologies, it’s time to change things up. This is now a great opportunity to read all about Lean Six Sigma and how it differs from the concept of Lean. It’s also an excellent opportunity to read about digital transformation and how it’s causing companies to pivot in similar directions as Lean. 

There is also an opportunity to examine how Six Sigma and Design Thinking can be combined to help reach new analytical and creative approaches. Alternatively, some midnight reading might be good for Digital Kaizen, which is all about how some companies want to transform the concept of continuous improvement. 

Conclusion 

Along with the companies mentioned here, Lean Methodology has benefited companies like Airbnb, Buffer, Groupon, and many more. There is no question that this methodology will continue to be a dominant way for new startups to find their niche and scale to that rare unicorn level of reaching a $1 billion valuation.
