Kdan Mobile Software Ltd., headquartered in Tainan, Taiwan, is a prominent global SaaS provider established in 2009. The company has built a reputation for developing productivity and content creation tools that empower mobile-first professionals. With a global footprint that includes offices in the United States, China, Japan, and South Korea, Kdan Mobile has successfully navigated the transition from simple app development to a sophisticated ecosystem of cloud-integrated solutions. Their product portfolio, which includes PDF Reader and DottedSign, has garnered over 200 million downloads, reflecting their strong market position. The company focuses on the 'hybrid workforce,' ensuring that creativity and productivity can happen anywhere, seamlessly bridging the gap between desktop power and mobile convenience.
The company was founded in 2009 by CEO Kenny Su, who previously gained extensive technical experience at the Industrial Technology Research Institute (ITRI) in Taiwan. Su's original vision was to capitalize on the nascent App Store ecosystem following the release of the iPhone 3G, identifying a gap in mobile-friendly productivity tools. Starting with a focus on PDF management, the company pivoted toward a broader 'Creativity' suite as mobile hardware capabilities evolved. The early years were marked by rapid user adoption in Western markets, which fueled the company's expansion into a multi-product firm. Su's leadership has been characterized by a commitment to user-centric design and a strategic focus on cross-platform functionality, which remains a core pillar of Kdan’s identity today.
Kdan Mobile has successfully secured significant investment rounds to fuel its global expansion and technological development. In 2018, the company completed a $5 million Series A round to bolster its cloud-based content creation tools. This was followed by a major $16 million Series B funding round in July 2021, led by Dattoz Partners, with participation from WI Harper Group, Taiwania Capital, and Golden Asia Fund (Mitsubishi UFJ Capital). This funding was strategically allocated toward international market penetration, particularly in the US and Japan, and the development of enterprise-scale collaboration features. More recently, reports indicate continued investor interest, highlighting the company's valuation growth and its trajectory toward a potential public offering, as mentioned by leadership in strategic briefings.
Kdan Mobile offers three primary product lines: the Creativity 365 suite, the Document 365 suite, and enterprise solutions like DottedSign. Write-on Video is the cornerstone of their multimedia offering, working in tandem with Animation Desk for 2D animation and NoteLedge for digital note-taking. These products are interconnected through Kdan Cloud, allowing users to move assets between applications—for instance, taking a storyboard from NoteLedge into Write-on Video to begin production. Their Document 365 line, led by the industry-standard PDF Reader, caters to high-volume document workflows, while DottedSign provides a legally binding e-signature service compliant with international standards, targeting the digital transformation needs of modern businesses.
Since its inception in Taiwan, Kdan Mobile has aggressively pursued a global expansion strategy. They established a US headquarters in Irvine, California, to better serve the North American market, followed by strategic offices in Changsha (China), Tokyo (Japan), and Seoul (South Korea). Their growth is characterized by heavy localization, including support for over 10 languages and partnerships with regional resellers. Kdan’s expansion is not just geographic but also sectoral; they have moved from individual consumer apps to enterprise-grade solutions, securing partnerships with educational institutions and large-scale corporations that require centralized management and high-level security compliance for their creative and productivity workflows.
In the last 18 months, Write-on Video has seen significant feature enhancements aimed at professionalizing the mobile editing experience. Most notably, the introduction of AI-powered auto-captioning has revolutionized the subtitling process for creators. The 'Pod' system was also overhauled to include more detailed scene description fields and improved template logic for specific genres like 'Unboxing' and 'Tutorial' videos. Integration with YouTube has been tightened, allowing for the direct export of project markers as SEO-ready timestamps. Additionally, the desktop versions for macOS and Windows received performance updates to support 4K 60fps editing, ensuring the software keeps pace with modern camera hardware and user expectations for high-definition output.
Kdan Mobile prides itself on a culture of innovation, agility, and inclusivity. As a global company, they emphasize a 'hybrid-first' work environment, allowing employees the flexibility to work from diverse locations—a philosophy that mirrors the purpose of their software. Their values focus on empowering the 'Modern Professional,' which translates internally into a commitment to continuous learning and professional development. They maintain a strong focus on DEI (Diversity, Equity, and Inclusion), supported by their multi-national office structure that brings together diverse perspectives from Asia and the West. This culture of freedom and responsibility is what founder Kenny Su credits for the company's ability to compete with much larger tech giants.
The community surrounding Write-on Video is vibrant and active, primarily centered around the 'Write-on Video Creators' Facebook group and Kdan’s own 'Creativity 365' community portal. Here, users share storyboarding tips, video tutorials, and technical advice. Kdan also engages its users through certification programs and design competitions, such as their annual 'iDesign' contest, which encourages creators to showcase their work using Kdan's suite. For developers, Kdan offers API and SDK options for their document technologies, fostering a developer ecosystem that extends the utility of their core engines into third-party applications, further solidifying their role as a foundational technology provider in the digital creativity space.
