Hi there,

Throughout September, we continued to see positive growth across key metrics. Most notably, we added more than $1M in cash over Q3 and finished September with $294K in net income, bringing year-to-date profit to $1.59M. It was our third straight month of $300K+ cash growth, and we’re on track to cross $4M in total cash on hand in October, a remarkable turnaround from our $2.7M low earlier this year.

This consistency is the result of the Buffer team staying focused and deeply committed to building for our customers.

Looking ahead, we’re investing in the foundations to support this momentum: expanding our team, preparing for our Community launch, and continuing to refine how we serve creators and small businesses around the world.

Read on for the September results and my reflections on what we’re learning as we grow.

  • Margins remained strong with Gross Margin at 84%, EBITDA Margin at 15.8%, and Rule of 40 at 39.6%. Net income finished at $294K, bringing YTD net income to $1.59M and projections for FY25 to $2.28M.

Note-worthy Updates & Reflections

Building the Team to Support Growth

We’re in a season of hiring as we continue to double down on areas that are working for us and invest in new parts of the product and our team.

We’re getting ready to welcome two new engineers and a growth marketer, and we’re continuing to expand across Customer Advocacy, Marketing, People, and Engineering. You can view open roles on our Journey page.

Each of these roles is key to supporting our growth, from improving product velocity to serving more customers faster.

Quality of Life Improvements

A small group of Buffer teammates partnered cross-functionally to remove friction in several key areas of our product. We’ve been quite pleased with the end results and shared all 18 changes to Buffer in this blog post.

Improving our Zapier support

This last month, we added support for to our Zapier integration after several user requests. Buffer users who leveraging Zapier can now add multiple images to TikTok posts, add a first comment on LinkedIn, and add topics to their Threads posts zia Zapier.
