Plumb

3...2...1... 🚀and we're live! Starting now, anyone can build AI workflows in Plumb. Which means anyone can monetize their flows instantly. Start building today at useplumb.com

@aarondignan So long and thanks for all the fish! 👋

major life update: we are shutting down @useplumb after several years of hustling on agentic workflow automation, we have decided to hang it up what we got right: ✅ Agentic Workflows > Agents - determinism and the ability to debug still matter guys (even Open AI gets this with agent builder) ✅UX/UI - the hand feel of building in Plumb is what I’m going to miss the most, nothing else even comes close ✅Structured Output - exquisite JSON schema out of every step unlocks so many cool possibilities, agentic branching among them ✅HITL - being able to interact with agents/flows via SMS, email, and Slack is so important, and nodes like “collect input” (that inject responses downstream) are 🤌 what we got wrong: ❌ We invented workflow subscription (and a bunch of tech like MetaJSONSchema) BUT nobody asked us to, and nobody cared ❌ As a result of that decision ^ we couldn’t easily utilize MCP, iPaaS, webhooks, API triggers, etc. and that severely limited what you could build on Plumb ❌ We didn’t pick a vertical, function, or high value set of tasks to solve on day one - instead we spent way too long playing with “nice to have” flows that were technically interesting but not operationally valuable If we did it all again, we’d do it differently. More learnings in a future post. For now, we want to thank our investors, including @BenjLerer @asymmetric_vc @greenfield_cap @humanvc @galeforceVC @theready @scottbelsky @ericries and many many more - you won’t find a more supportive bunch out there. If you're raising, ask them. 🚨 Finally, we’re officially looking for a home for this team, so if you want to snap up an elite squad of applied AI nerds… my DMs are open Please RT this for reach bc this team hangs the moon 👉 @chaseadams @keyavadgama @petekp @tihalstead @abtweedy @sarashpit And now for what's next...

@IMJustinBrooke @theaaron fair! we just mean "people that know how to AI and want to offer flows to an audience of subscribers"

@theaaron @useplumb They lost me at “where technical creators”

I've sold about $72,000 worth of AI agents (as a side hobby), here's what I learned... 1. YOU are not your customer. Small businesses barely know how to change their printer ink, let alone fix an AI agent you built for them. They want very simple AI agents. - It should do 1 job very well - It should be hard to break - It MUST be easy to use 2. Fortune 500 companies don't need you. They already have IT and dev teams. You'll bang your head against the wall with long sales cycles, decisions by commity, and then ultimately have to deal with a tech team that feels threatened by you. @mindstudioai is what I've been using, am an ambassador. They have pre-built agents that you can start with literally today. You can copy them into your account and see how they work under the hood. N8N might be cool to you, and personally I think it's a very neat platform. The problem is my end client does not think it's cool. N8N scares them and overwhelms them. If you want to learn more about actually selling AI agents, instead of playing with them, DM me. I'd love to chat with you about your plan. 33 MILLION small businesses in the U.S. alone, and ALL of them want you to automate their payroll, lead gen, bookkeeping, social media, etc.

I know the bar for Apple's AI is on the floor, but I didn't realize Genmoji is THAT bad? Our design engineer was able to make an emoji generator in @useplumb in less than a day that actually makes what you ask for...and then there's Genmoji with the same prompt lmao

@tobi Nice! I went ahead and just built a signature cocktail generator on @useplumb based on this prompt. Hope everyone has good libations tonight! 🍹 Try it for free: app.useplumb.com/sites/plumb/si…

Get out your crayons.

API calls to LLMs fail all the time. Time outs. ⏰ Errors. 🤬 GPUs on fire. 🔥 So we built a fallback system into @useplumb Now you can enable automatic retry or specify specific fallback models for any LLM step.

do you have specialized expertise that could be encoded in a prompt or series of prompts? would you like to monetize that? I will interview you, build an AI workflow in @useplumb based on what you know, and we’ll promote it here together.

We launched a chat feature at @useplumb that lets you trigger flows straight from chat. Makes for a huge upgrade to my scheduler flow - feels like having a real EA. No form filling, I just have to drop a message with the basic details and it does the rest.

I wanted to read more AI research papers, so I built a flow to help me 😈 It's like a PhD intern that reads everything published and tells me about the most interesting one

I spent 50+ HOURS building an AI workflow that helps you post quality content on LinkedIn every day ⚡️ Leaders know they should be posting on LinkedIn more often, but they don't because they're locked in scrolling on X 😂 This @useplumb flow is the solution: → Give it your url and a writing sample one time → Exa scrapes your website and determines who your ideal customer is → Claude Sonnet 4 creates a list of questions your customers care about → One question and a winning LinkedIn formula are chosen at random every day → The flow emails you to ask if you have any thoughts on the topic → Then it conducts research on the topic, bringing back up-to-the-minute data → And emails you the perfect draft (including an image) using your voice, your initial thoughts, and the research → You can reply with feedback, have it publish straight to LinkedIn, or copy/paste and iterate on your own Turns what should take an hour into 5 minutes. The best part? You don't have to copy and paste this into n8n or some other platform that requires a PhD. You can just subscribe to it and I'll keep making it better for you every week. Want access to the LinkedIn Writer? Follow + comment "PLUMB" & I'll DM you the link to try it for free

If your AI workflow takes 5 minutes to build, then that’s your moat. 5 hours, better. 50 hours, now we’re talking.

Plumb is Substack for AI workflows. Build an automation with no code. Share it with your followers. They can subscribe and get updates when you improve it (like an app). Set your price and you get paid every time it runs.

We took @claudeai's new "previous conversation" aka memory feature for a test drive and WE HAVE THOUGHTS

Tuesday, 8:43 PM. Kids finally out for the night. Cracked the code: turned hours of copywriting grind into a 20-minute, AI-powered workflow with @DudaPlatform + @useplumb AI. @doorloopapp clients get custom web copy fast (minus the agency markup). I get my nights back. Sometimes the best breakthroughs happen after bedtime, with coffee and stubbornness. Want to see how?

Anyone actively using @useplumb ? Looks interesting; a bit like @n8n_io combined with @zapier and Langflow.

Why wouldn’t you jump on this? @useplumb is like n8n for agencies or people who are monetizing their automations No real business wants to get handed a 74-node n8n or Make flow they have no clue how to use, and can’t update

I can vouch for him, he's good for it
