The problem

Manual prospect research is the slowest part of sales

Sales and marketing teams spend hours per week researching prospects: industry, headcount, funding stage, tech stack, location. The work gets done by a junior person Googling each row, copy-pasting notes into a spreadsheet, and missing things. AI does this same work in minutes, with web search, and at a fraction of the cost.

How it works

Three steps from input to output

  1. 1

    Upload your spreadsheet

    Drop an XLSX, XLS, or CSV file. We parse it instantly and show you the columns and row count so you know exactly what we're working with.

  2. 2

    Describe what to find

    In plain English, tell us what columns to add. "Add company website, employee count, industry, and recent funding round." We'll plan out the columns and ask you to confirm.

  3. 3

    AI enriches every row

    Claude Sonnet researches each row using web search, fills in the new columns, and shows you progress in real time. Download the enriched file as XLSX when done.

What you get

A clean enriched spreadsheet you can act on

Your original data plus the new columns you asked for, populated row by row with researched information. Download as XLSX with proper column widths and formatting.

  • Original columns preserved exactly
  • New columns added based on your plain-English brief
  • Per-row research powered by Claude with web search
  • Real-time progress: see each row complete (or error) as it happens
  • XLSX export ready to drop back into your CRM, sequencer, or analytics tool
  • Failed rows clearly marked so you know what needs manual review

Features

Built for real sales and marketing workflows

Web search per row

Each row gets researched against the live web — not just trained data. So you get current info on funding rounds, recent hires, product launches, and anything else with a public footprint.

Plain English instructions

No prompt engineering. Tell the tool what you want like you'd tell a junior sales rep: "Add their LinkedIn, headcount, and what their main product does." It figures out the columns.

Multi-column enrichment

Add 1 column or 10. Common combos: company size + industry + tech stack, or website + LinkedIn + recent news, or anything else you describe.

Progress visibility

Watch each row light up as it completes (or errors out). For a 100-row enrichment you can monitor exactly where things stand instead of staring at a spinner.

XLSX export with formatting

Output is a clean Excel file with column widths set sensibly and your original sheet name preserved. Ready to import back into HubSpot, Salesforce, or wherever the data needs to go.

Failed-row flagging

When the model can't find something with confidence, the row is marked instead of guessed. So you can quickly review the misses without scrubbing the entire export.

Built with privacy in mind

  • Spreadsheet data is processed in memory and never written to disk
  • All transfers use TLS encryption (HTTPS)
  • Anthropic's Claude API does not train on your data per their enterprise policy
  • Web search queries reference publicly available information only

FAQ

Common questions

What kind of data can the enricher find?
Anything publicly available on the web. Common requests: company website, LinkedIn URL, employee count, industry, recent funding, location, tech stack, product description, founder names, recent news. It can't find non-public information (private contact details, internal metrics, etc.).
How accurate is the enrichment?
Claude Sonnet with web search is significantly more accurate than older AI tools because it cites live sources. For well-known companies, accuracy on basic firmographics (size, industry, location) is very high. For niche or stealth companies, results may be sparser. Failed rows are flagged rather than hallucinated.
How long does enrichment take?
Roughly 5-15 seconds per row depending on what's being researched. A 100-row enrichment with 5 new columns typically takes 10-25 minutes. The page shows live progress so you can leave it and come back.
What's the row limit?
Up to 5MB per upload, which translates to roughly 10,000-50,000 rows depending on column count. Each row consumes one quota unit, so plan accordingly: free tier handles 25 rows, Pro tier handles 500, Business tier handles 2,500.
Will it hallucinate data?
The system prompt explicitly instructs the model to mark fields as unknown rather than guess. Web search citations help ground the responses in real sources. That said, AI is never 100% — for high-stakes data (legal, financial, compliance), spot-check the output.
Can I run this on an ongoing list automatically?
Not in the self-serve tool, but yes if we set it up. Same engine can be wired into a pipeline that pulls new leads from your CRM, enriches them automatically, and writes the data back. Book a free consultation to scope it.
