The Scenario
You're a competitive intelligence analyst at a B2B SaaS company. A new competitor appeared in last month's pipeline review — smaller, moving fast, winning deals you expected to close. Your VP of Product wants to know who else is playing in that space: companies with similar tech profiles that you haven't mapped yet.
You have BuiltWith access. You have an Excel workbook set up for tracking. What you don't have is a methodology for this — nobody on the team has done a lookalike analysis before, and the VP wants something on her desk by Thursday.
The bad version:
- Search BuiltWith's recommendation interface for the seed domain, get a list of similar sites, manually copy each domain into column A of your worksheet
- For each recommended domain, navigate to its BuiltWith profile, read the technology list, paste the relevant categories into the adjacent columns
- Repeat this for 50 domains, then realize the VP actually wants 100, and there's no fast way to extend what you've already started without redoing the column logic
The point of this analysis is to find patterns across 100 companies — something you can only see once the data is in a structure you can actually work with.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent that lives inside your Excel workbook. It reads the workbook context and uses BuiltWith's recommendation engine to generate a lookalike list — then writes the domains, countries, and technology profiles directly to the worksheet.
Open a blank Excel workbook and ask:
Use BuiltWith recommendations to find 50 websites with technology profiles similar to salesforce.com and write domain, country, and matching tech categories to this worksheet with headers in row 1.
SheetXAI pulls the lookalike list, fetches the technology categories for each result, and builds the table in one pass.
What You Get
- Row 1 with headers: Domain, Country, Matching Tech Categories
- One row per lookalike domain, with the root domain, BuiltWith-detected country, and the technology categories shared with the seed domain
- The worksheet is ready to filter immediately — you can ask SheetXAI to isolate domains in a specific country or segment by shared technology
What If the Data Is Not Quite Ready
I want to use multiple seed domains — find sites similar to both salesforce.com and hubspot.com
Use BuiltWith to find websites with technology profiles similar to both salesforce.com and hubspot.com. Pull the first 60 results that appear in both recommendation sets. Write domain, country, and shared technology categories to this worksheet with headers in row 1.
I only want lookalikes from specific countries
Find 50 websites with tech stacks similar to salesforce.com using BuiltWith recommendations. Only include results from the United States, United Kingdom, Canada, or Australia. Write domain, country, and matching tech categories to this worksheet.
I want to add a column showing which technologies they share and which they don't
Use BuiltWith to generate 50 lookalike domains for salesforce.com. For each domain, write domain, country, Shared Technologies (categories that match salesforce.com), and Unique Technologies (categories detected for this domain but not for salesforce.com) to columns A, B, C, D.
Full competitive mapping in one shot
Use BuiltWith to generate 75 lookalike domains for salesforce.com. Write domain, country, and full technology list to columns A, B, C. In column D, score each domain: "Close Match" if it shares 5 or more technology categories with salesforce.com, "Partial Match" if it shares 2–4, "Loose Match" if fewer than 2. Sort by column D with "Close Match" rows first.
The entire competitive landscape analysis runs in a single prompt — no manual copying, no column-by-column formatting.
