Woofun AI reports that Anthropic launched Claude Tag, a Slack-native AI assistant, on June 23, directly competing with startups like Viktor. Internal data from Viktor indicates the launch acted as a growth catalyst, with the startup gaining 407 new sign-ups while losing only 5 customers on the same day. Viktor leveraged the product release for customer acquisition through targeted Google Ads campaigns.

Viktor distinguishes itself by supporting both Slack and Microsoft Teams, connecting to over 3,000 tools, and allowing users to switch between underlying models such as OpenAI and Google. While Claude Tag remains tied to the Anthropic ecosystem, Viktor emphasizes operational memory and context ownership as key advantages. Despite the short-term traffic boost, Viktor acknowledges Anthropic as its primary threat due to brand recognition and enterprise relationships.
