> SpecStream is the live web data engine for teams and agents. This is the Markdown copy of https://specstream.ai/for/enrichment. Every page, with what SpecStream does and costs: https://specstream.ai/llms.txt # Fill in the empty cells in the list you already have. SpecStream is the live web data engine for teams and agents. For enrichment, bring the rows you have, from a CSV, Excel, Google Sheets or Airtable, and SpecStream fills only the cells that are empty: website, phone, owner, email, the tools a site runs, or anything you can describe. Each new value links to the page it came from.

Import the list or link the sheet. Pick the rows and the details to add. SpecStream looks each row up by its website, a page link or an ID such as a company number or a DOI, reads the live web for the missing details, and writes them into the empty cells only. Your own values are never overwritten. A linked sheet is checked every day for new rows, so enrichment can keep running as the list grows. Send the filled rows back to the sheet or your CRM, matched to the records already there. ![A wooden crate full of index cards and photographs, every one filed in its place.](https://specstream.ai/world/marketing/card-crate.small.webp) ## Who is it for?

CSV, Excel or pasted rows, or a linked Google Sheet, Excel workbook or Airtable view, up to 20,000 rows a list. Common headers map themselves, your extra columns stay, and every address lands on the map free. ## What it costs Importing, mapping and exporting are free. Each row SpecStream finds and checks costs 5¢, and a row that matches pays its rate instead: 10¢ with up to 5 details. A named person's email adds 10¢, a phone 25¢. 1. Standard **$0.10**/match Up to 5 facts a row. Balance Roughly covers Free ($10) **100** rows Pro ($19) **190** rows Scale ($99) **990** rows Team ($499) **4,990** rows 2.

One built from the company’s own pattern counts and is labeled likely. A row without it pays its rate alone. **+10¢ a row** Their phone Added the same way, on any list. **+25¢ a row** A detail you mark as needed For each company that fit everything else and was left out without it, at most 10 for each row you asked for. The ones that have it come back as rows. **5¢ a company** Related records A related list, such as a company’s jobs or a creator’s posts, includes 10 records a row. Each further 10 are 10¢. **10¢ per 10** Rechecks 5¢, 15¢ or 50¢ a row to read it again and say what changed. A contact adds half its price too. **Half the rate** Rows from your own list For each one SpecStream finds and checks. One that matches pays its rate instead. Importing is free, and a row it can’t find costs nothing. **5¢ a row** Placing addresses on the map Each imported address lands at its postcode, and rows with their own coordinates keep them. **Free** Every account starts with $10 of work, no card. Pro is $19 a month for $19 of work, and the rates are the same on every plan. [Every plan and price](https://specstream.ai/pricing.md) ## Is it for you?

A row it finds and checks costs 5¢, and one that matches pays its rate instead. ### **How big can a list be?** Up to 20,000 rows and 20 MB a list. Rows that can't load are listed with their row number and the reason, and the rest load. ### **Can it enrich from my CRM?** Export from the CRM, import the file, and send the filled rows back.
