About Custos Media Technologies
At Custos, they want to provide a globally effective way to combat media piracy by tracing a leak to its source in a decentralized way using cryptocurrency. As soon as the Bitcoin reward is claimed, content owners are notified that a leaked copy of their content has been discovered as well as the identity of the person who was entrusted with that specific copy. The team has grown to cover various experts in the fields of watermarking technology, the economics of piracy, and the use of decentralized systems and the Bitcoin blockchain.

Custos Media Technologies Reviews
Write a ReviewDelivered on scope, on time, and with code quality that passed our strictest review
Declan Hartley / Chief Digital Officer - Southern Cross TechnologyMar 16, 2026
Project summary: Evolving open banking obligations required us to rebuild our API layer from the ground up. The architecture needed to be compliant by default, not bolted on after the fact.
What made the most difference in practice was the quality of the engineering judgment on this team. Not the ability to execute a specification — that is a baseline expectation. The ability to recognise when a specification was suboptimal, explain why, propose an alternative, and support the client in making a decision about it. That consultative dimension elevated the output beyond what the brief described and resulted in a product that is more fit for purpose than the one we had originally specified.
Commercially transparent throughout — no hidden assumptions, no bill shock at the end, change requests that were fair and clearly explained rather than used as a margin-recovery mechanism
We underestimated the input required from our subject matter experts during the requirements phase. The team flagged this early but our resource planning did not fully reflect it — our responsibility, not theirs
Questions & Answers
Technically rigorous, commercially grounded, and a genuine pleasure to work with
Nathan Prescott / VP of Technology - Ironclad Insurance GroupMar 08, 2026
Project summary: Our internal product thinking was strong but our execution capability in this specific technology domain was limited. We needed depth, not generalism.
The technical quality of the final deliverable is the easiest thing to point to. The automated test coverage is thorough, the deployment pipeline is reliable, the documentation is genuinely useful rather than ceremonially produced. But the metric I keep returning to is the number of post-launch conversations we have not had to have. No incident calls at two in the morning. No emergency patches. No retrospective discussions about what went wrong. The absence of those events is the evidence I would show to someone considering this vendor.
Collaborative culture that made the team feel like a genuine extension of our organisation, strong asynchronous communication across time zones, zero-drama handling of the inevitable mid-project changes
Time zone coordination required some deliberate overlap management from both sides in the first couple of sprints, after which we had an efficient async rhythm that worked for the whole project
