Announcing our $10M Seed Round led by @Accel alongside incredible angels 💫 It's never been easier to build & ship software. But it's also never been harder to monetize it. We’re building the open-source monetization platform to empower future one-developer unicorns. How? 🧵

we’re a billing platform. nobody has ever been excited about a billing platform. but you’ll be excited the first time it tells you a customer is burning through your margins before they sink your business.

Back in 2012, it was encouraged for startups to delay monetization. Growth first, revenue later. Fortunately, our industry learns from mistakes. That’s why we reward ARR today. … extrapolated after a week from launch and with negative gross margins.

Given upgrades and the current scientific methodology of calculating AI ARR: $/minute × 1440 (day) × 366 (assume leap year) I'm thrilled to report that Polar surpassed $21.1M ARR within 10 minutes of launching Polar Plans today. Fastest growing SaaS, ever.
Excited to introduce Polar Plans 🚀 Offering lower transaction fees transparently as you grow. No "volume based discount" gatekeeping. Available to anyone, today. With Scale, growing startups can get lower fees with Polar than pure PSPs, but with all MoR benefits included 🤯

Support is a known achilles heel for Merchant of Records. We've always been praised for ours (mostly – nobody is perfect), but in February, we started seeing it get away from us – reaching ~600 tickets/day in the backlog. Excited to have aggressively turned the trend around despite 10x in growth. → Hired a Director of Merchant Operations to help scale our support, risk and success team. → We shipped our own AI support chat. → We shipped our own continuous account review agent. → We shipped self-review onboarding against our AUP and integration requirements. → We've shipped a ton of internal tooling → We've answered 5,000 tickets We're far from done, but excited about the momentum in the right direction.

Had the most mind blowing AI experience today. Scene At the country house and the water pump stopped. From the former owner, I knew there had been a history of issues. Only hours before, I had brought a plumber over ($500 - including on-call fees due to weekend) to help install a new washing machine due to separate issues. We had not been able to wash clothes for 2 weeks. So the water pump quitting on us after a) only one load of washing clothes & b) shortly after the on-call plumber had left was... bad timing. The cost of getting the plumber to drive to us on a weekend alone was $250 before labour. After restarting everything and still experiencing issues, I decided to call the former owner for advice given the history: "Uhm, I've never seen *that* issue before. Try A, B, C... Z". None worked. So I flipped in the manuals some more. Felt like a different language. That specific problem felt easy to solve... ChatGPT I took a few photos of the manuals and gave brief context to ChatGPT. So I could chat with the manuals instead. Of course, it nailed it. It also went a step further and started giving some really good troubleshooting advice. Nothing surprising here. Still magic, but accustomed magic. Yet, I guess it encouraged me. I was also desperate to wash clothes after having spent $1.2K on a new machine installation to solve a 2 week problem. So I felt willing to try what felt like a hail mary. I walked into the pump house and started snapping photos. Quite shitty ones - some attached here. Of the fuse box, fuse chart, all equipment, wiring, plumbing. Here are some images of the pump house. Given your troubleshooting advice what would you have me do? Expecting more of a generic interpretation of the messy images and parroting the former guide in context of some lightweight new information. No. I immediately got instructions to turn of a specific fuse followed by one piece of the equipment and let it rest for 30-60 minutes. Combined with a logical reasoning behind it and endless more clarification of what all these wires, fuses and plumbing meant. I went from feeling completely clueless about the pump house to at least now having a sense of understanding – regardless of the outcome. But of course, I also did what it said since it now felt fully logical. Fast forward 60 minutes: Activated the fuse and turned the equipment on again. Voila, water was back baby. Neighbours started calling me The ChatGPT Plumber and I'll wear that title with honour. Perhaps this is obvious to some reading this. Trust me, I get it too. At least all the individual technological feats that went into accomplishing this, but it's like knowing all instruments: It does not mean you've experienced all the combinations of them together, i.e there are endless new symphonies that can be created.
