We Are Zeals

A communication tech company based out of Tokyo, Japan. We are a group of scrappy and hungry bunch from different walks of life, looking to make an actual impact on the way people and businesses communicate through our AI Chatbot technology. We obsess over bringing hospitality to everyone--be it our customers or you! You’re an individual with unique needs. As an employer we are ready to roll-up our sleeves and change the status quo if it means to make your experience better!

Everyone matters here at Zeals--regardless of their background. Be it a young coding prodigy (Yes, our CTO just turned 23) to someone who hardly speaks Japanese. Everyone has a voice. We went from a small, humble apartment to a 300 people organization across multiple time zones (with no sign of stopping) in the span of 7 years--all that thanks to our members’ contributions. So, if you join us, get ready to raise up your voice and spend your time contributing to projects that matter!

Our last 2 years have been phenomenal and we are still growing (with so much untapped potential). While we can’t attract you with ping-pong tables or all-you-can-drink espresso bars. We can promise you full flexibility on your workstyle and co-workers that you can brag about to your friends, family or anyone you meet the next time you go out for a party!

About Zeals

株式会社Zealsは、業界トップクラスの“チャットコマース”事業を主力に、“接客DX”事業にも注力し、「おもてなし」という日本文化の強みをデジタル化する挑戦を通じてクライアントの事業変革に貢献しています。

チャットコマース事業

チャットコマース『Zeals（ジールス）』とは、「ネットにおもてなし革命を！」をコンセプトにした、ユーザーがAIと会話しながら商品を購入したり予約したりできるサービスです。

ユーザーはLINEやFacebookなどのチャットアプリを通じ、従来は実店舗に限られていた接客体験を、Webやアプリケーション上で体験できます。チャットボットによる“ヒアリングファースト”な接客体験により、通常のLPと比較して約5倍の購買率向上を実現。旅行、化粧品、サロン、金融業界などに幅広く導入頂き、約400社のお客さまの売上増をお手伝いしています。

日本では「チャットボットはカスタマーサポートを自動化するのに使うもの」という認識が一般的ですが、海外ではチャットボットをコマース・マーケティングに活用する事例が多く生まれてます。

中国で人気のwechat上には800万体のチャットボットがマーケティングに活用されており、アメリカでもConversational Commerceと呼ばれるチャットボットを活用してマーケティングを行うサービスが増えています。チャットコマースはまさにこの"会話を通じて商品を買っていただく"ことに特化したチャットコマースを提供する業界初のサービスです。

接客DX事業

チャットボットをコアとして、ビデオツール等お客さまの課題に応じた手法を組み合わせ、実店舗での接客をデジタル空間で実現する一気通貫したサービスです。AIと人のハイブリッドにより最適化された接客体験をユーザーへ提供することで深いインサイトやニーズ、悩みに応えます。

今後は、チャットコマース事業と接客DX事業を主軸に様々な業界でのオンライン接客を広げ、海外展開や音声への拡張を目指します。また、現在の主軸事業の他にも、ビジョンに沿った新規プロダクトの開発やコアテクノロジーの開発を進め、日本が誇るおもてなし文化に新たな人と人とのつながりを創造します。

ここに注目！

Zealsは、テクノロジーを通じて新たな人と人のつながりを創造し、世界に通用する革命を起こすことを目指しています。この大きな志を達成するために働く人への投資を惜しみません。徹底した自社開発を行っており「テクノロジーに対する理解と投資」重視しています。2021年4月には総額18億円の資金調達を完了し、今後は更に積極的にテクノロジー、そして人に投資をしていく方針です。来年には、現在の2倍のエンジニアを採用する予定です。

企業カルチャーの特徴としては、Zealsは典型的な日本の会社ではありません。日本の伝統的な階層形システムや生産性より労働時間を重視するような働き方は全くありません。例えば、ZealsのCTOは20歳で就任しています。年齢ではなく、能力とやる気のある人に積極的にチャンスを与える文化があります。また、18ヵ国以上のバックグラウンドを持つグローバルメンバーなど、多様なメンバーが揃うフラットな環境です。フレックス制度、リモートワーク制度などが充実しており、柔軟な働き方も可能です。積極的に新しい技術を取り入れる社風があり、新しいテクノロジーが大好きなメンバーが集まっています。

グローバルかつ、エンジニアドリブンな企業であるZealsのカルチャーに共感いただける方にぜひジョインいただきたいと思っています！

Zeals' policies during COVID-19 are as follows:

Overseas candidates are welcome to apply — and can even continue working from abroad!
There are currently no meetings that require your physical presence (especially during COVID-19)
For anyone who does relocate to Japan during COVID-19, Zeals will cover any costs for quarantining, testing etc.

Japanese Language Policy
At Zeals, the developers use primarily English (dev-related discussions happen in English on Github or Slack). There might be occasional discussions in Japanese, but most Slack messages are in English (or both languages).

As for meetings, all dev-related ones take place in English. In the past they used Japanese at times, but now they have a clear policy to use English since they have several members who don’t speak Japanese.

Given the above, Japanese skills are not required for engineers. But one unique aspect of the culture at Zeals is that many Japanese members are working on their English while many non-Japanese members also work to improve their Japanese skills.

Since before Zeals was focused on global expansion, around 40% of their members were non-Japanese but most spoke Japanese fluently. In order to build a truly global team, these multilingual members will typically help out when communication is needed between people who don’t speak a common language. In this fashion, Zeals has slowly been turning English into their official language for engineers.

Even now Zeals has many multilingual members that proactively support the rest of the team to ensure smooth communications.

Even outside of the development team, important company-wide announcements are made in both English and Japanese. For example hiring announcements, new product launches etc. they’re announced in both Japanese and English.

Also, they provide simultaneous interpretation for presentations at their monthly all-hands meetings, among other tactics to ensure that everyone gets the information they need.
Paid Leave
- All Japanese public holidays off
- 10 days of PTO (awarded 3 months after joining)
- Summer holiday, Year-end holiday, Childcare leave, Congratulations/Bereavement leave
