How Buffer went from a two-page test to paying customers in seven weeks and a multi-million-dollar business
TL;DR
Joel Gascoigne built Buffer to schedule his own tweets, tested demand with a two-page site, and launched on November 30, 2010, seven weeks after starting. He got his first paying customer within four days. Buffer has raised only $4 million, grew past $22 million in annual recurring revenue, and in 2025 reported about 67,000 paying customers. The lesson: test demand and pricing before you build the real product.
How it started
Joel Gascoigne wrote on Buffer’s blog that he wanted to take the scheduling feature of Twitter clients and make that one feature excellent. His idea was a way to queue tweets without scheduling each one. He had suggested it to existing apps and they had not built it, so he decided to build it.
He says he started coding before testing the business, then stopped and tested demand first. He made a two-page minimum viable product, tweeted the link, and asked people what they thought. Some gave their email and feedback, which he treated as early validation.
Next he added a pricing page in between the two pages to see whether people would click on paid plans. A small number did, so he started building the real product in evenings and weekends over seven weeks.
How they got the first customers
Buffer went live on November 30, 2010, timed to a Hacker News thread about a November Startup Sprint. Gascoigne says he received useful feedback from the Hacker News community.
He had his first paying customer within four days of launching what he called a rough-around-the-edges product. After that, he wrote, he stopped adding features and shifted attention to marketing and customer conversations. By about two and a half months after launch, Buffer had over 500 users, with around 4 percent upgrading to paid plans, according to his February 2011 post.
What drove growth
Gascoigne said in a 2025 Business of Software talk that his co-founder Leo Widrich joined in 2011, they went through an accelerator program, and they raised $450,000. By the end of 2011 Buffer was a team of three with annual recurring revenue of about $200,000. By the end of 2013 it had 16 people and $2.3 million in ARR. The company added LinkedIn and Facebook after starting with Twitter, and in 2013 became known for salary transparency.
In 2014 Buffer turned down its largest acquisition offer and raised a $3.5 million round at a $60 million valuation, keeping control. The company raised $4 million in total across two rounds and has spent $10 million since 2017 buying out investors and alumni.
Growth was not a straight line. ARR plateaued around $22 million in about 2020 and fell about 20 percent over three to four years, to $17.1 million. By the talk, Gascoigne said Buffer was back to about $22.7 million in ARR, growing 22 percent year over year, with about 67,000 paying customers and around $2.5 million in net income on track for 2025.
Lessons you can copy
- 1Test demand with a page before you write the productA two-page site plus a pricing page told Gascoigne whether anyone cared and whether they would pay. It cost days, not months.
- 2Test pricing early, not just interestThe extra pricing click showed which plans people clicked. Willingness to pay is a stronger signal than a signup alone.
- 3Use a public deadlineGascoigne tied his launch date to a Hacker News challenge. A public commitment kept him from endlessly polishing.
- 4Shift to marketing once the product is good enoughAfter the first paying customer, he stopped piling on features and focused on customers and promotion.
- 5Keep control of your companyBuffer raised little money and kept its board small. That control let the company pick a slower, independent path after an acquisition offer.

Not entirely. It raised $4 million in total over two rounds, the last in 2014, and Gascoigne says it has since spent $10 million buying out investors and alumni.
What happened when Buffer’s growth stalled?
Gascoigne told Business of Software that ARR plateaued around 2020 and declined about 20 percent over several years before returning to growth by 2025.
