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

Sendergram was born from my career as a rock photographer ( and music video producer (Underground showreel) pitching clients creative ideas, sending examples, delivering artwork and collecting payment. Through this experience, I built an affordable, integrated solution to simplify, enable, protect, and certify the creative process for all creative types working with creative assets.

Instant and permanent, irrefutable record

Sendergram helps to protect users not only by registering a file to prove attribution but also by tracking and registering the whole communication, transaction and events: what was discussed? what was agreed upon? All participant interaction is logged through an immutable time-stamped activity record. In this way, Sendergram is uniquely focused on auditing a communication trail in addition to registering and time-stamping a digital file in the blockchain.

  • Proof a file, creative work, discussion or idea occurred at a certain point in time
  • Proof a document or communication hasn’t been tampered with
  • Proof of exactly what each recipient received, opened view, discussed, downloaded
  • Proof of entire communication, transaction agreements between parties
