Copyright In Motion

It’s your work: Protect it, Blockchain it, Sendergram it!

Sendergram was born from my experiences and frustration as a music photographer ( and as a producer of over a 100 music videos with the lack of copyright protection, accountability, and recourse I had when pitching clients creative ideas, sending examples, delivering artwork and collecting payment. I set out to build an integrated solution for all creative types to simplify working with creative assets, to help protect artists copyright throughout the creative process and to get paid on delivery.

Redefining Trust

A trusted creative environment

Sendergram enables people to engage in trusted transactions with full confidence in the integrity of the assets and data being exchanged (photos, songs, scripts, video, code, manuscripts) or any important files. An audit trail of all files transactions and events are encrypted, time-stamped, registered, stored, and verifiable in the blockchain. Sendergram supports all creative types including photographers, filmmakers, musicians, writers, designers, sales, agency or production teams.


Data integrity, immutability and trust

In order, to maintain data integrity, and provide verifiable proof of authenticity each Sendergram automatically generates a time-stamped digital signature (cryptographic hash) for each individual file or creative work. The file signatures are then combined with all sender and recipient activity including file downloads, views, additions, comments and payments. As new events happen, the registration is updated and a new blockchain receipt is generated.
