Benefits of Sponsorship

Gather neutral, engineer-created content

Articles for sponsor calendars are contributed by Qiita users. This allows sponsors to collect authentic, unbiased content rather than advertisements or promotional material.

High visibility during Qiita’s most active period

By gaining exposure during December—the month when Qiita sees its highest page views of the year—sponsors can reach a vast audience of engineers.

Recommended for companies that:

Want to increase awareness and promote services or tools targeting engineers

Aim to strengthen branding as a 'technologically strong company' and accelerate engineering recruitment

Seek engagement with engineering communities and encourage high-quality technical output

Accelerate your technical branding with a 'Gift Calendar'

Sponsoring companies can set their own unique theme (e.g., product usage, desired technical domains for recruitment) and select outstanding entries from submitted articles. This provides an ideal opportunity to receive high-quality technical content directly from engineers interested in your company’s technology.

Last year, sponsors contributed gifts totaling 2 million JPY in value. Generous prizes further boost user participation, creating significant excitement year after year.

Additionally, we offer plans for continued engagement with participating engineers through award ceremonies, post-events, and more.
