last 24H has been crazy, #2 on @ProductHunt
with @propane_ai , all the learning, and user growth.
Now the real work starts 😅
Already #1 on @ProductHunt. Thank you to everyone who showed up today. 🚀

My friend @greenlieber just launched his new product — Propane on @ProductHunt!
Go check it out and show him and his team some love! 🤗🎉

We're live. Today we open Propane up to the world. Would mean everything to get your support. 🚀 go.usepropane.ai/phlive
We need to stop thinking that what we've built so far can fix product management. More tokens, more AI, more tools—it's not working.
Context is still scattered, everyone is reinventing the wheel.
We're building something to change that, more on this later this week. 🔥
We're launching on @ProductHunt this week and opening it up for everyone.
Follow to be first when we go live. go.usepropane.ai/phlive 🚀
Talked to a dozen people building their own product management stack this week. The Venn diagram is basically a circle, everyone's rebuilding the same 90% with Ai. Same loop, same workflows, same setup, from scratch 🧐
Please, someone convince me this is the best way to work going forward?
A few days ago we shipped the State of the Agentic PM 2026.
We'd wanted to do this for a while. Built with our own tool, @propane_ai, @cursor_ai @vercel and @n8n_io. Dogfood the whole way through check it out.
Yesterday we launched State of the Agentic PM 2026. We wanted to understand how the PM role is actually changing. AI interview, 5 to 10 min, $10 to charity, open sourced. Data coming in. We need a massive dataset.
We are planning to build a massive qualitative dataset on the future of product management. Help us scale it. For the community and for charity.

We're building the biggest qualitative research project in PM history, please support us 🙏 @lennysan @cagan @joulee @cohentomer @karrisaarinen @johncutlefish @villaumbrosia @karrisaarinen @antonosika @danshipper
We're building the biggest qualitative research project in product management history, open sourced and with $10 going to charity for every interview completed. The PM role is at a real turning point, everyone feels it.
Tell us what you think comes next.

Proactive AI Agents
Today’s AI products are reactive. You give the model a prompt, it responds with an answer. These are useful, but I’m excited about products that take this further and shift the paradigm from “ask → answer” to “observe → act."
These agents will continuously monitor context in the background across all of your connected tools and data, predict what matters, and take action before being asked to do so – much like a human does. So instead of you prompting the model, the model will start prompting you.
Examples here could include agents that remind you about tasks you forgot to complete, resolve customer issues before support tickets are filed, or debug and ship code fixes automatically.
This shift represents a new paradigm where AI products behave more like humans and less like tools. We’re already starting to see this dynamic with products like OpenClaw, Poke, and more - and we’ve only scratched the surface of capabilities here.
We’re accepting applications for the next cohort of @a16z @speedrun – If you’re building the next generation of AI products, apply online.

one ritual I'm glad to see the back of: the standup
15 min every morning describing work that could be read..
in @propane_ai , I can just ask. no breaking flows!
15 min/day back to human collaboration & problem solving - stuff that matters!
what can we build to save you time?

@Amplitude_HQ, @hidovetail, and @cannyHQ are now live in Propane.
Usage data + research + feedback — in the same canvas where you write specs and run agents.
No CSV exports. No tab-switching. No manual synthesis.

Today is a hard day. I shared this note with the @linear team today: We’ve made the difficult decision to increase our workforce. This is not a cost-cutting exercise or a reflection of anyone’s performance. We’re simply reimagining every role for the agentic AI era. We’re hiring. We’re sorry about that.
