Key people at Kiko.
Kiko was founded in 2005 by Justin Kan (Founder) and Emmett Shear (Founder).
Kiko was an early web-based calendar application designed to offer universal access, easy sharing, and a user-friendly experience for personal and professional scheduling. It targeted anyone needing to keep and share calendars online, including business professionals and event organizers. Kiko aimed to solve the problem of fragmented and inaccessible scheduling by enabling calendar access from any computer or mobile device, with features like inviting non-users to events and seamless sharing. Despite its innovative approach, Kiko struggled to maintain growth momentum due to intense competition and market timing challenges, ultimately leading to its acquisition after a brief lifespan[1][2][3].
Founded in 2005 by Justin Kan and Emmett Shear—who later became notable for founding Justin.tv and Twitch—Kiko emerged from the founders’ recognition of the growing need for online productivity tools. The idea was to create a calendar that was as easy to use as paper but leveraged the power of the web for sharing and accessibility. Early traction was promising, supported by Y Combinator backing in the Summer 2005 batch. However, the rapid emergence of Google Calendar in 2006, with its superior integration and brand power, overshadowed Kiko’s initial lead. Internal challenges such as divided focus, slow execution, and team issues further hindered its ability to scale[1][2][3].
However, Kiko lacked a unique angle strong enough to fend off larger competitors and suffered from execution delays and team missteps[1][2][3].
Kiko was riding the early wave of cloud-based productivity tools and the shift toward web applications accessible from anywhere. The timing was critical: the mid-2000s saw rapid adoption of online services, but Kiko’s early entry was eclipsed by Google’s ecosystem integration, which became a dominant market force. Kiko’s experience highlights the importance of rapid scaling and differentiation in a market where tech giants can quickly leverage their platforms to dominate adjacent services. Its attempt to integrate calendars with other web tools anticipated later trends in API-driven productivity ecosystems, influencing how startups approach calendar and scheduling solutions today[1][3][6].
While Kiko itself did not survive, its founders went on to significant success in the tech world, and its story serves as a cautionary tale about timing, focus, and competitive strategy in tech startups. The calendar and scheduling market continues to evolve with AI, integrations, and mobile-first design shaping future solutions. Companies building on Kiko’s vision must prioritize rapid execution, seamless ecosystem integration, and unique value propositions to thrive. Kiko’s legacy is a reminder that being first to market is insufficient without speed and differentiation—principles that remain vital in the tech landscape.
