Viktor works in lemlist for you. Ask in Slack or Microsoft Teams.
Viktor is an AI employee that connects to lemlist and helps you run cold outreach sequences and follow up with prospects, running 14 lemlist actions for you like Get Lead, Add Lead To A Campaign, and Update Lead In Campaign. Ask in plain English from your workspace; Viktor does the work in lemlist and reports back. Viktor connects with an API key.
Viktor connects to your lemlist account and completes work in it. He doesn't just answer questions about lemlist, he takes the actions on your behalf and delivers the finished result to your workspace.
Unlike workflow builders such as Zapier or Make, there is nothing to configure - no triggers to map, no workflows to maintain. You describe the outcome in plain English, and Viktor picks the right lemlist actions, chains them with the other 9,800+ tools he connects to, and asks for approval before anything sensitive runs.
