Start with your best customer, run Similar Company Finder, and get lookalike B2B accounts worth pitching next.
Check any match against the four attributes that determine company similarity. Every result shows which ones it shares with your seed account, so you see why it made the list.
Structured company data on the record, so the list stays inside the market you sell to.
Headcount, so the target companies stay at a scale your product and pricing fit.
City, state, or region, so a company similarity search returns a territory a rep can work.
Technology Insights surfaces companies running the same tools, a strong signal of similar businesses with a shared problem.
With every attribute switched off there is nothing left to match on. Turn at least one back on.
A lookalike business search turns one account you already trust into a set of companies that resemble it, and then the people to contact inside each one.
A customer, a closed-won deal, or a company you know uses a competitor.
Lookalike companies built from industry, size, location, and tech stack, so you see why each one is on the list.
Filter to the roles you sell to and export verified contacts, without leaving the result list.
Pick the roles you sell to and the same search returns named, verified contacts at every matched company.
Any company detail page in ReachStream Prospect: a customer, a closed-won deal, or a competitor’s customer.
The Lookalike Company Finder builds from that record’s own attributes. No brief to write, no seed list to upload.
Drop an attribute you do not care about, or add a filter you do. A similar company search is a normal search you can keep editing.
Reach the right roles at every matched company, verified in-platform before a credit is spent.
The company you start from decides what comes back. Find Competitors and Similar Companies from one record: start on a customer, a closed-won deal, or a rival’s account to find lookalikes of three very different kinds.
Two of the 54 reviews on our G2 profile, quoted as they were written. One founder and one operator, both working a whole segment rather than one account at a time.
“As a founder across multiple SaaS products like Serpdog, EcommerceAPI, and Scrapingdog, high-quality outbound lead generation is crucial for scaling. ReachStream has made this possible with its ultra-targeted B2B email lists, including niche segments like CTOs, Ecommerce Founders, and Healthcare professionals.”

Twelve questions people ask before using a Similar Company Finder. Want to see it run against your own customer list? That is the fastest version of this conversation.
Open one of those customers in ReachStream Prospect and run Similar Company Finder. It reads the industry, headcount, location, and technology on that record and returns companies that share them, so you find similar companies without writing a brief or uploading a list.
Start from an account that already works rather than from a description of one. A company similarity search built on structured company data shows which attributes each result shares, so you find similarities between businesses instead of guessing at them. Look for a tool that exposes those attributes and lets you edit them.
Run a lookalike business search from any customer record. ReachStream Prospect returns B2B lookalike companies matched on the four attributes it holds for every company, and you can drop or add attributes to widen or tighten the result.
Identify similar companies from two or three won accounts and compare the overlap. Companies that appear across all of them match your ICP on evidence rather than on a workshop definition.
Judge a Competitor and Similar Company finder on three things: whether it explains why each result matched, whether you can edit the match after it runs, and whether the contacts inside those companies are verified. ReachStream Prospect shows the shared attributes, keeps the result editable, and verifies emails before export.
A lookalike company is one that resembles an account you already sell to on the attributes that predict fit: industry, size, location, and the tools it runs. Similar businesses with comparable business models tend to share the same problem, which is why lookalike companies are a common starting point for target account lists.
Open that company in ReachStream Prospect and hit Similar Companies. The Lookalike Company Finder returns similar companies from the same record, and each result shows which attributes it shares with your starting account.
Work a segment instead of one account at a time. Finding lookalike accounts from a closed-won deal gives you a target account list where every company already resembles a buyer, and you can pull verified contacts at each one without leaving the result.
No. Running a similar company search does not spend export credits. Credits are spent only when you export verified contacts: one per contact with an email, ten per phone number, one per company export.
Every plan, including Free. Plans differ in how many Similar companies search runs you get, not in whether the feature is available. The pricing page has the full table.
Yes. A Similar companies search behaves like any other search, so you can filter to the roles you sell to and export verified contacts from the same screen. Deliverability is guaranteed at 90% on the emails you export.
No. ReachStream Prospect does not provide intent data. Similar company insights tell you who resembles your best accounts, which is a targeting signal, not a timing one.
Start there. Run Similar Company Finder on your best account and export your first 100 contacts free, verified before download, no card and no contract.
