Premium boutique creative agency serving top-tier technology brands, acquired by Twitter in 2021
Ueno was a globally recognized creative and digital agency founded in 2014, with offices in San Francisco, New York, Reykjavik, and Los Angeles. The agency built a strong reputation for delivering high-quality brand identity, UX/UI design, web development, and digital product strategy for a roster of prominent technology and consumer brands. Ueno was widely admired in the design community for its distinctive aesthetic sensibility, cultural voice, and commitment to craft. The agency worked with clients including Airbnb, Google, Uber, Lyft, and various other tech-forward companies, positioning itself at the intersection of brand strategy and digital execution. While not a traditional AdTech company, Ueno operated in the broader digital marketing and brand experience ecosystem, helping companies shape how they presented themselves across digital touchpoints. In February 2021, Twitter acquired Ueno to bolster its in-house creative capabilities. Following the acquisition, Ueno's team was integrated into Twitter's internal design and creative organization. The Ueno brand effectively ceased to operate as an independent agency entity after the acquisition, with its founder Haraldur Thorleifsson (known as Halli) joining Twitter as a senior executive before later departing.
