If your LEAD.bot is matching the whole company, you probably have added the bot to a TEAM that includes all the people in your company. Please delete the bot from that team. 

Create a new TEAM (not channel )and only invite the users you would like them to be matched. If you set the team to be a public team and announce the news in the GENERAL channel, people might join voluntarily as well. The bot will only match the people within the matching team. (if you add the bot to a team, the team will become a matching team.)
