San Francisco-based AI marketing startup GIGR said on Tuesday it raised $5.4 million in a pre-seed round.

The round was led by global venture capital firm BRV Capital Management, with Mirae Asset Venture Investment participating. Angel investors included KRAFTON outside director Bora Joung, a former Bill.com executive, former Hyprsense CEO Jihoon Yoo, whose company was acquired by Epic Games, and Crew Capital.

GIGR said it sees the next stage of marketing not as another tool, but as a workflow that turns performance signals into rapid iteration. To that end, it said it developed a marketing platform that supports the full creative lifecycle using multi-agent AI, and launched its first product, Playad, in the third quarter of 2025.

Playad is an AI-native creative platform that starts with interactive advertising and extends to images and video. It is designed to help marketers learn quickly from performance and immediately reflect the results in the next creative, supporting efforts to reduce uncertainty that arises during iteration.

GAGR said it is continuing collaborations with a range of global companies related to Playad, and plans to expand its market push by targeting marketing organizations with high volumes of creative production, mainly in gaming and commerce.

GIGR CEO Jaeyeon Cho (조재연) said, "Marketing performance depends on how quickly you learn from creative and execute." He added, "Through Playad, we will make iteration the default and focus on eliminating uncertainty in the digital advertising decision-making process."
