You vibe-code. Now vibe-sell.
The same AI-assisted workflow you use for everything else—but for finding customers. Define your ICP, AI finds prospects, you refine and send.
You don't anymore. AI generates it, you refine. Sales works the same way now:
Remember when you had to write every line of code by hand?
Vibe-coding changed how you build
You describe the component. AI generates the code. You review, refine, ship. It's faster, better, and you stay in control. You'd never go back to writing boilerplate by hand.
Vibe-selling changes how you find customers
You define your ICP. AI finds prospects talking about your problem. AI drafts personalized messages. You review, refine, send. Same workflow. Different output. No more spending 3 hours researching one person on LinkedIn.
Quality over volume—just like your code
You don't generate 1000 lines of code and hope 10 work. You generate the right code and refine it. Same with sales: 10 perfect messages beat 100 generic ones. FirstSell is Cursor for finding customers.
The habit that actually gets you clients
Ten minutes a day. A system that remembers everything for you.
Pick
While you browse LinkedIn, X, Reddit, or Facebook, add prospects in one click. AI scores them against your Ideal Customer Profile.
Experiment
Build an experiment: every prospect gets a full conversation plan. First message, follow-ups, and what to do whether they reply or not.
Follow up
Every day you open the app and see who to message and why. Review, send, and FirstSell logs the replies and moves each conversation forward.
How FirstSell Works
From prospect to customer, with every conversation on record
Add prospects while you browse
From profiles, posts, or comments on LinkedIn, X, Reddit, and Facebook. One click and they're saved to your account.
- LinkedIn, X, Reddit, and Facebook
- One-click import
Build the experiment
Pick a group of prospects. AI scores their fit with your ICP and prepares a conversation plan for each one.
- Fit score and the reason behind it
- Full plan: if they reply and if they don't
Follow every conversation
Today's queue shows who to message and what to say. Review, edit if you want, and send. The extension picks up the replies.
- Who to follow up with today, and why
- Full history per prospect
Close and learn
When the experiment closes, leads and customers stay in your contacts with the whole conversation, and you see what worked so you can adjust the next one.
- Leads, customers, and discarded
- Learnings for the next experiment
An AI chat writes you a message. FirstSell takes you to the customer.
Any agent can write. What it can't do is remember your conversations, tell you who to follow up with, and learn from your results.

Deep Dive: Vibe-Selling
Everything you need to know about the new way to find customers.
What is Vibe Coding (And Why It's Killing Your Business)
You build apps because they're interesting, not because someone asked. Then you launch to crickets. Here's why—and what to do instead.

Read ModeHonest answers about vibe-selling
It's a workflow: you define what you want (your ideal customer), AI does the grunt work (finds prospects, drafts messages), you refine and send. Instead of spending 3 hours researching one person, you spend 30 minutes on 10 qualified prospects.
It's a workflow description, not marketing fluff. It describes how you use AI to assist with outbound while staying in control—like using AI for design, writing, or coding, but for finding customers. Some companies are trying to trademark the term. We're just using it to explain the concept.
Most tools either blast 1000 generic messages (mass automation) or just rewrite what you already wrote (AI wrappers). Vibe-selling is about the workflow: AI finds the right people, generates context-aware messages, you refine before sending. Quality over volume. Human in the loop.
No. The term started with developers because they already use AI workflows, but it works for any 1-person B2B business. Consultants, freelancers, coaches—anyone who needs clients and hates spending hours on cold outreach.
Mass tools send 500+ messages with basic personalization ('Hi {{firstName}}'). Vibe-selling sends 10 messages that reference what the prospect just posted about. One gets ignored, the other gets replies. Volume vs quality.
Yes, but it's slow. You'd manually search social media, read posts, research profiles, draft messages, track who you contacted. That's 2-3 hours per prospect. Tools automate the grunt work so you spend 30 min total on 10 prospects.
No. The term is getting popular and other companies are building similar tools (some even trademarking 'vibe selling'). We're focused on 1-person businesses who want quality over volume. Others target sales teams or specific industries.
Join the FirstSell waitlist for early access. Or start manually: define your ideal customer, browse social media for people talking about your problem, send 5 personalized messages a day. The workflow matters more than the tool.
Your next customer might be in a conversation you stopped following.
FirstSell remembers every conversation and tells you who to message today.
