Haranaga’s Expertise Graduated with a Master's degree in Mechanical Engineering from the Graduate School of Science and Engineering at Aoyama Gakuin University. Started my career as an engineer in 2001 as part of the first batch of new graduates at Yahoo Japan Corporation. Subsequently, ventured into entrepreneurship, launching various web services centered around C2C. Notably, my founded company, SparkLab Inc., operated a marketplace for handmade items, which was acquired by GMO Pepabo, which runs Minne, Japan's largest handmade marketplace. In 2008, I co-founded Bracket Inc. (later renamed [STORES.jp](http://stores.jp/)), serving as the CTO and leading numerous C2C services, including peer-to-peer car sharing and model matching sites. In 2011, I was also a co-founder and CTO of note Inc., which runs [note.com](http://note.com/), Japan's largest content platform, which is listed on the Tokyo Stock Exchange Growth Market. In 2015, I joined REAPRA PTE. LTD. in Singapore as CTO, engaging hands-on in investment decisions in Southeast Asia and Japan, supporting product development for investee companies, and accompanying entrepreneurial education. My expertise lies in technology, experience design for products and services, product management, and managing global development teams. 青山学院大学の理工学研究科で機械工学の修士号を取得。2001年にYahoo Japan Corporationの新卒第一期生と してエンジニアのキャリアをスタート。その後、起業に踏み出し、C2Cを中心とした様々なウェブサービスを立 ち上げる。特に、私が設立した会社SparkLab Inc.は、手作り品のマーケットプレイスを運営し、日本最大の手作 りマーケットプレイスであるMinneを運営するGMOペパボに買収された。 2008年にはBracket Inc.(後にSTORES.jpに改名)を共同設立し、CTOとして、ピアツーピアのカーシェアリン グやモデルマッチングサイトを含む数多くのC2Cサービスをリード。エンジニアの育成スクールの立ち上げ運営を経て、2011年には、日本最大のコンテンツプラッ トフォームであり、東京証券取引所グロース市場に上場しているnote.comを運営するnote Inc.の共同創業者兼 CTOを務めた。 2015年には、シンガポールのREAPRA PTE. LTD.にCTOとして参加し、東南アジアと日本での投資決定に関与し、出資先企業の製品開発をサポートし、起業家の伴走支援に従事。得意領域は、経営戦略、事業戦略、商品戦略、技術戦略を横断した戦略立案、実践。主にITを用いたプロダクトおよびサービスのエクスペリエンスデザイン、プロダクト運営、グローバル開発チームのマネージメント。
