Key points

• Pluto has raised $42M total, including an $8.5M seed led by TLV Partners and a $34M Series A led by Jump Capital.
• Startup says about 60% of risks it detects come from tools vibe-coded by non-developers, with finance teams the largest source.
• Pluto reports over $2M in annual recurring revenue and more than 30 enterprise customers since selling began in April.
• Its software monitors agent behavior in real time and can stop actions or prompt agents to ask for confirmation.

Why it matters for marketers: Marketing and content teams using AI tools may face new internal security reviews, so brand-approved AI workflows and vetted tool lists will matter more.
