I used it to collect sales lists when launching a new BtoB business.
The list can be collected just by launching the tool, so we use the collected list to send emails and make tele appointments.
The decisive factor is "cost performance". Collecting a list of companies of this class would cost more than 50,000 yen per month, but IZANAMI costs only 5,980 yen. I can't find any reason not to install it.
