Thrilled to announce our $10M Seed led by @Accel today, with continued support from @AbstractVC & @MischiefVC, and incredible angels. Join us and let's build the future of billing for developers to empower the next generation of software 🚀
Polar@polar_sh

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? 🧵

@samlambert Makes me happy to hear solid engineering posts getting traction in the day and age of slop canons and zero code reviews.

I want to hang out with design teams in Europe. Visit their office, work for a day and learn from how they operate. Any ideas who I should connect with?

@xn1cklas Yes, and in batches. Raised our $10m Seed about a year ago, but recently got a surge in "Congrats on the fundraise!" paired with "We can help with sourcing open source developers looking for better funding and monetization tools"... 🤦🏼‍♂️we pivoted from that 24 months ago.

Getting so much spam calls & AI slop emails/DMs lately, it’s absolutely infuriating, and a guaranteed way of making me principally against working with these companies.

@mitsuhiko Agree. All these founders focused on $ boasting vs building something they truly care about, is overall tiring and unfortunately rewarded in the current cycle.

Our @stripe account just got closed for high risk of disputes. We've transacted thousands of dollars in our first few months of business, successfully identified and refunded several payments that had a potential for fraud, and only have ever had three disputes.

@birk @polar_sh I didn’t, but you guys really need to allow us to add our own policies that customers must accept before making a purchase.

If you considered @polar_sh, but opted for another MoR/billing/payment solutions recently, why? What did we miss?

accidentally attended a zoom interview with a @supabase t-shirt, and got rejected almost instantly after because "that kind of technological bias makes me seem technically weak" my bad chat 👍

The tech workforce is splitting in two A year ago, we ran the first large-scale survey of how tech workers feel about their jobs and careers. What emerged we summarized in four words: burned out, but optimistic. Today, we're back with the results from our 2026 survey, and it's a tale of two workforces. Half of tech right now feels amplified by AI—more capable, more confident, more excited than they've been in their entire career. The other half feels shaken by it—less sure of their value and whether there’s still a place for them. Which side of that line you fall on predicts how you feel about your career more than anything else, including your role, seniority, company size, or any other measure we collected. The workforce is bifurcating into two realities. A few other takeaways that surprised us: + Significant burnout jumped from 44.7% to 55.7% in one year, while career optimism fell from 54.8% to 48.7%. A worrisome trend. + 53% of tech workers would steer a newcomer away from a career in their own role, even when they're optimistic about their own future. + The biggest AI fear is of being squeezed to do more work. Only 22% worry about “losing my job to AI.” Far more worry about being expected to do more for the same pay, getting trapped in an unsustainable pace, and the quality of their work declining. The question that best predicts how a tech worker feels about their work, in 2026, is no longer "What do you do?" or "Where do you work?" It’s "What has AI done to your sense of who you are?"

Number of seats at @polar_sh have an exponential growth! The feature has been behind a feature flag since the beginning. Now, it's mature enough to release it to everyone 🚀

1) Should never be the case. We had a bad incident last month indeed, but making a lot of investments to prevent similar ones in the future since resilience is #1 priority. 2) We don’t make any money on those and agree. Aim to ship some big things that will allow us to mitigate and slice them.

@birk @polar_sh I am a current user but few reasons if I will move will be * extended downtime, Polar had few last month. * Fee, I am okay with payment processing fee but then there are payout fees, international fees and currency conversions fee. All these adds up, there are options in market

@terzi_federico @polar_sh I hear you. We don’t make money on those, and will do orchestration and new payout options which will allow us to get rid of them.

@birk @polar_sh 70% of my revenue comes from outside of the US + I'm based in Sweden. Between international payment fees and payout fees Paddle ends up being far cheaper, even with the discounted startup plan

Birk Jernström@birk·
We have integrations with both, and lot of our customers build their own form of PPP that’s more bespoke. For transparency, I’d always rather partner with integrations on these vs build it ourselves. We have so much room for innovation in billing and helping with usage based billing. By going wide an integration native affiliate and other adjacent services, I think we spread ourselves thin and create something meh, versus going deep in our domain and partnering with others who do the same. That’s my 2c and reasoning behind us not having invested in these areas like LS and others.
