Fastest company ever to $1b annualized revenue Nope it’s not Higgsfield or Cursor or Cognition. Met a data company yesterday that did 0 revenue in November 2025 and 80m “in month revenue” in September 2026. They will hit $1b annualized from 11 months of being started. They are still under the radar so I can’t share who they are. Hopefully soon, with their permission. I don’t make the rules.

Promoted employee posts (This post was written for LinkedIn, but the same logic applies to customer / employee posts on X. A domain buying company promoted my positive post about them for several months, and I believe it was hugely ROI positive for them) Serval does an excellent job of getting every employee to post on LinkedIn about their Serval experience, and then promoting those posts. These promoted posts are the best ads since they are diverse, authentic and credible in a way no brand campaign can be. Each post reaches a different network, speaks in a different voice, and carries the implicit endorsement of someone who chose to stake their own reputation on the company. It also compounds. Every post is a recruiting pitch, a customer reference, and a culture signal at once. Prospects see a team that believes in the product. Candidates see people who are proud of where they work. Competitors see momentum. And paid promotion flips the usual math. Instead of spending to make a generic message feel human, Serval spends to amplify messages that are already human. The creative costs nothing, and it's the best creative they have. The lesson for founders: your employees are your most underused distribution channel. Make it easy and safe for them to share their story, then put money behind the ones that land.

All the focus on top line growth ignores burn / efficiency. There are actually two paths, one is super fast growing but highly inefficient / high burn. The other is fast growing but efficient. If you're in a large market and have grown revenues from 5 to 15M this year, or 3M => 12M, burning sub-5M (burn ratio of 0.5) and you can't raise, please message me. We at @MarathonMP absolutely love companies that compound efficiently for years.

Great list. We @MarathonMP have a strong and value-added presence in NYC thanks to my partners @AlexGorgoni and @ChaseAPackard, who I believe are two of the best and most thoughtful investors in tech today. In Marathon fund 1, 50% of portfolio companies are HQed in NYC. We also have a great space for founders to work out of. Two of our companies were incubated in the space.

Thank you Ramesh for your friendship and partnership over the years. Excited to see the @MarathonMP hat in the wild, and hope to see it become an essential piece of tech swag that every entrepreneur and leader proudly sports to showcase their commitment to the marathon of company building!

Our swag. Our brand. @MarathonMP New colors coming soon!

Great collab between @MarathonMP and our friends at @GVteam on the consumer AI builder dinner. Most participants want to do it again, which is a good signal :)

SWAG At @MarathonMP, our swag game is focused on our hats. While we have great branded shirts, backpacks, etc, it’s the hats that founders, LPs and others love (and love to wear). A founder’s termsheet closing condition was that they get one hat in every color :) The hat simply reads “Marathon”. The word is incredibly malleable and everyone can affix their own meaning to it (for example, the Nike logo on the side, coupled with Marathon, can lead the observer to the conclusion that the wearer is a runner, and in fact that’s the most common “stop in the street” reaction our hats get :)) Of course, the reason we chose Marathon as our name is that it epitomizes the endurance and grit needed to build legendary companies. And we are here as the founder’s supporter and helper through the company building marathon. But there’s no reason to not have fun along the way, and swag is a great way to showcase the philosophy. They also come in 6 different colors (more coming soon!) so you can build your own collection, one for each day of the week. We hope to get one to you when we meet you in person!

My partner @MBGilroy's interview perfectly captures our philosophy at @MarathonMP. One of our core tenets is to prove to founders BEFORE we invest that we will be one of your best SDRs (i.e. help connect you with potential customers) and also one of your best recruiters (i.e. help connect you with potential talent).
