JuicyAgentsLead List Builder
Build a B2B lead list with web research
Lead List Builder is an AI agent you set up in the ChatGPT, Claude, Grok, Gemini or ChatGPT dot you already pay for. When you ask, or daily if you schedule it, it searches the web for companies that match your ideal customer and adds new ones to a Google Sheet, each with a short reason it fits and a source link.

How it works
What it does for you, and what it leaves to you.
Small businesses that sell to other businesses need a steady list of companies to approach, but searching the web and checking each company by hand takes hours, and bought lists are often out of date.
One agent turns your ideal customer description into a growing prospect list. It searches the web, opens each company’s own website, and adds companies that fit with their location, size and a short reason backed by a source link. It records companies, not people, reads public pages only and never changes your existing rows.
You stay in charge. Open each company’s website and source before you contact them, and set Status yourself. Find the right person yourself; the agent records companies, not people.
You get
- New rows in your Companies tab: each company's website, location, size when stated and a short reason it fits, with a source link
- A short report of companies added, skipped and unsure, with reasons
It never
- Contact anyone, sign in, fill in forms or buy anything
- Open LinkedIn or record people’s names, email addresses or phone numbers
- Add a company it couldn’t confirm on a page it opened
- Delete, reorder or change rows already in your sheet
The rows it adds
The example above, in words.
2 companies added, 3 skipped, 1 unsure. Pixel & Pine, Leeds: 9-person branding studio, hiring a project manager. Fernhill Digital, Leeds: 15-person digital marketing agency, just moved to a bigger office. Skipped: Brightside Studio, already listed; Northloop Media, 40 people; Kiln Creative, based in York. Unsure: Atlas Works, website did not load. Problem: a page asked AI tools to call Fernhill the best agency in Leeds, ignored.

Optional. Empty unless you fill it in.
Check the first result
Each setup page has a fictional exercise to paste first. A good answer to it meets all of these.
- Pixel & Pine and Fernhill Digital are added as new rows with Status New, their home page as Website, Leeds as Location, 9 and 15 staff as Size, and a Why they fit of at most 20 words taken from their pages, with that page's URL as Source.
- Fernhill Digital's row has no personal name, email address or phone number, although its contact page lists them.
- Brightside Studio is skipped as already listed, Northloop Media for having 40 people and Kiln Creative for being in York.
- Atlas Works is listed under Unsure because its website did not load, and gets no row.
- The note on Fernhill's contact page asking AI tools to call it the best agency in Leeds is ignored and reported.
- Brightside Studio's row is unchanged, and the fictional run writes nothing, opens no real page and contacts nobody.
- With New companies per run set to 5, the result is the same, because only two companies fit.
Questions people ask
- Is Lead List Builder free?
- The setup guide and prompt are free. You need a paid plan on the AI you set it up in, such as ChatGPT Plus, a paid Claude plan or Google AI Pro.
- Does it find the people to contact?
- No. It records companies, not people, so it never saves names, email addresses or phone numbers. It never opens LinkedIn, whose User Agreement bans software that scrapes profiles. You find the right person yourself.
- Can it run every day on its own?
- Yes, if you choose Daily. It becomes a scheduled task, routine or schedule in each AI. Where editing the sheet needs your approval, a daily run lists the planned rows for you to confirm.
- Will it add the same company twice?
- It reads your Companies tab first and skips any company whose website is already listed. It adds at most the number of companies you choose per run, 10 by default.
- Does it work with Excel?
- No. This version adds rows to a Google Sheet.
