Tiga.ai, a leader in signal-based prospecting, announced that it has raised $2 million in funding. The round was led by Bull City Venture Partners, with participation from Cascade Seed Fund and Virginia Venture Partners. The biggest challenge in B2B selling is reaching accounts that are in a high potential buying cycle. These accounts are often identified by custom buying signals that take significant manual effort to discover. Tiga is the first AI agent purpose-built to autonomously discover custom buying signals and activate personalized outreach to the buyer.
