AI Contract Management Cloud 'Hubble' Integrates with 'Adobe Acrobat Sign' for Automated Contract Importing and Compliance

Hubble Inc. (Headquarters: Shibuya-ku, Tokyo; CEO: Shinpei Hayakawa; CTO: Katsuya Fujii; CLO: Tomoya Sakai), the provider of the contract operations and management cloud service 'Hubble', has launched an API integration with Adobe's e-signature solution, 'Adobe Acrobat Sign', as of May 18, 2026.

This integration enables the automatic importing of contract data completed via Adobe Acrobat Sign into 'Hubble' and 'Hubble mini'. It establishes a system for centralized management of contract data scattered across various e-signature services and minimizes the burden of complying with the Electronic Book Storage Act.

## Background: Eliminating 'Analog Double Work' from Digitalization
While the spread of e-signatures has advanced the digitalization of contracts, it has also created new challenges for legal and administrative departments. One such challenge is 'analog double work'—manually downloading signed PDF files from e-signature systems and re-uploading them to contract management systems for consolidation.

This manual process not only increases the workload for legal teams but also carries the risk of human error, such as forgetting to save files or missing data entries. Furthermore, the strict management requirements of the Electronic Book Storage Act have added a significant burden to teams ensuring legal compliance.

In response to these challenges and direct feedback from users at the 'with Hubble' user group, Hubble developed this feature to enable seamless synchronization with Adobe Acrobat Sign and create a centralized database compliant with tax laws.

## Key Value Provided by the Integration

### Automated PDF Import for Both Sent and Received Contracts
Contract PDFs that reach 'Complete' status on Adobe Acrobat Sign are automatically stored in designated folders within Hubble and Hubble mini. This supports both contracts sent from the user's account and those received and signed from third parties, completely eliminating the manual labor of downloading and uploading files.

### Compliance with the Electronic Book Storage Act and Prevention of Human Error
By bypassing human intervention, the system ensures that the final PDF is stored directly in Hubble, eliminating risks of oversight. Hubble has obtained JIIMA certifications for both 'Electronic Transaction Software Legal Requirements' and 'Scanner Storage Software Legal Requirements'. By using the 'Full Compliance Option', users can apply certified timestamps and minimize the burden of managing data from multiple e-signature services in accordance with the law.
