Partner use cases
How organizations use AuthorHash gift codes.
📚
Publishing Platform Onboarding
"Welcome to our platform. Your first AuthorHash certificate is on us."
Include a gift code in every new author's welcome email. Cost at Growth tier: $4.00 per user. Perceived value: $11.99. Authors associate your platform with protecting their work from day one.
✉️
Manuscript Submission Protection
"Before you submit, protect your work."
Add a prompt to your submission workflow. Authors timestamp their manuscript before sending to agents or editors. Position it as a platform feature, not an upsell.
🏆
Writing Contests & Awards
"Every entry is AuthorHash-protected."
Give each entrant a gift code. The certificate proves the entry existed before the deadline, protects unpublished work shared with judges, and eliminates timing disputes.
🔒
Investigative Journalism & Whistleblowers
"Protect your evidence before you share it."
Distribute codes to field journalists and sources. Zero-knowledge architecture means your organization never sees the evidence — only the source and the mathematics know what was timestamped.
🎭
Writer Guilds & Associations
"Your membership includes 3 AuthorHash certificates per year."
Bundle certificates into membership tiers. At Scale pricing, 3 certificates per member costs $9.00/year — a high-value benefit at modest cost.
🎓
Academic Institutions
"Timestamp your research before publication."
Provide certificates to researchers, PhD candidates, and faculty. Establish priority of discovery for pre-prints, datasets, and novel methodologies.
What every gift code includes
Full $11.99 certificate. No compromises.
