Every company in the country, and the people who run it.

Kotka is a verified index of Canadian companies, with a date on every fact.

Three habits keep the index honest. Every fact carries the date it was last checked. A website is marked confirmed only after it has been checked against the company’s own name and phone. And nothing is harvested from customers’ inboxes or address books, ever.

What you get, and what it costs.

Looking is free. Credits are spent only on reveals, exports and enrichment, and never twice for the same person.

Search that never costs a credit

Filter companies and people by industry and NAICS code, province and city, employee and revenue range, department and seniority. Count, page and build lists for free, up to a daily limit on results that keeps the database from being copied.

Free on every plan

The company record, free to read

Name, address, company phone, website, NAICS code, size and revenue where known, and the date behind each field. Reading a record counts toward the same daily limit as search results.

Free on every plan

Decision-makers on record

Owners, officers and directors with title, seniority and department mapped to a published taxonomy. Reading them is free; only a verified email is paid.

Free on every plan

Verified email, one credit

Every address is checked against the mail server before it is shown. A credit buys one the server confirms; one it cannot confirm is free. Re-viewing a contact you already revealed is free forever.

One credit per confirmed email

Enrich your own lists

Upload a CSV with company names or domains and get the index fields back at the same credit price as the interface. Search results export as CSV.

Credits on export only

Freshness on every record

Each record says when it was last checked, and companies that have closed are taken out of search.

Included

Correction and removal built in

Every record carries a control to report an error and a request to be removed, answered by a person. Deletion propagates to exports.

Included

A record you can defend, not a row you have to trust.

Every field on a Kotka record says when it was last checked. This is a real record from the index, shown exactly as a signed-in user sees it before spending anything.

Verified, not scraped from inboxes

No contributor network reading your mail, no address book upload. Every record is checked on its own merits and dated.

Main street is in the index

The electrician with nine staff and the dental clinic with two partners are covered like any public company.

A real industry taxonomy

A NAICS code on more than nine in ten companies, with a published crosswalk, rather than one self-reported label.

A welder at work, sparks flying — **The contractor, the clinic, the shop and the hauler.** Businesses that never made it into a contact database, because they were never on anyone’s list.

Per seat. Credits pool at the team.

Eight rules, published, so the bill is never a surprise.

Search is free, always.

Filtering, counting and list building never consume a credit. Each person can view a set number of search results a day, which keeps the database from being copied.

One credit reveals a verified email.

Company phone, address, industry and size cost nothing. Nothing is charged unless data is returned.

A reveal that finds nothing is free.

Nothing is charged unless an address comes back. Some domains accept mail for any address, so no mailbox can be confirmed there; that address is labelled unconfirmed, as our best guess, and is free too. A credit buys an address the mail server confirms.

Re-viewing is free forever.

A contact you have already revealed never costs a second credit.

Unused plan credits roll over.

Up to twice your monthly credits, while your subscription is active. Yearly plans get the same rollover as monthly, since credits are granted monthly on both. Plan credits expire when a cancelled subscription’s paid period ends.

Every seat brings its own credits.

Add the whole team. Each seat adds a monthly allowance of credits and export records to one shared balance, and the running balance shows before any action is confirmed.

Export is metered, and reading has a daily limit.

Reading records costs nothing, up to a daily limit that keeps the database from being copied. A person costs a credit the first time they leave Kotka, and every exported row counts toward your plan’s monthly allowance.
