Registered Business

App Grove Field Co., Ltd. is the official registered business name operating from Office 7, 38 Test-daero, Seocho-gu, Seoul. We were established in 2019 to address a gap we observed repeatedly: families accumulating cryptocurrency reserves across multiple hardware signers without any documented register of devices, custodians, or recovery procedures.

Origin

Our founders spent years assisting relatives and acquaintances who lost access to family reserves after a single signer’s device failed, a passphrase was forgotten, or siblings disagreed about which derivation path held the primary holdings. The pattern was consistent — technical competence among individual signers, but no shared documentation binding the arrangement together across generations.

App Grove Field was founded to provide that binding documentation through structured consultations, not software products. We work air-gapped, never request private keys, and deliver written registers that survive personnel changes within a family.

Our Approach

We treat each family reserve as a custodial arrangement spanning decades. Our consultations focus on verifiable facts: device serial numbers, firmware versions, xpub fingerprints, geographic key distribution, and plain-language recovery procedures. We avoid promising specific investment outcomes and do not manage funds on behalf of clients.

Team

Jae-won Park — Lead consultant. Former systems administrator with fifteen years of experience in key management practices. Facilitates multisig ceremonies and register documentation.

Eun-hye Kim — Documentation specialist. Prepares bound register documents, recovery procedure drafts, and conducts follow-up balance verification sessions.

David Okonkwo — Client relations. Schedules consultations, manages inquiry responses, and coordinates on-site visits for families outside Seoul.

Values

  • Documentation over memory: Written registers outlast individual recollection.
  • Air-gapped by default: Private keys never touch our systems or networks.
  • Family-readable language: Recovery procedures must be understood by non-technical signers.
  • Honest scope: We document arrangements; we do not manage investments or promise returns.

Community

We participate in Seoul-area digital asset custody discussions and contribute educational articles to our journal on multisig practices, offline verification techniques, and family reserve planning considerations.
