A signature isa measurement,not a ceremony.

Sennasign is a chronograph for documents. Route a contract, witness the hand, stamp the proof — three sectors, one lap, sealed under eIDAS and ESIGN.

S/01 — Sector breakdown

Three sectors.
One lap.

Every signing event in Sennasign is split into three measured sectors. We don’t hide the wall-clock — we publish it. The apex is where draft, route, and stamp meet under one cryptographic timing block.

S/02 — Specification stack

Trust, but
serialise.

We don’t buy compliance badges from a stock library. Each certificate Sennasign claims is its own engineering part — with governing body, revision, scope, and a hash that any auditor can verify against our public statement.

Note · only the standards above are claimed. Any further certificate will appear here as a serialised part — never as a generic badge.

S/03 — Apex chart

Most vendors brake
into the corner.

We plotted six competing platforms on a chart we do not enjoy building. Throughput on X, judicial admissibility on Y. Most cluster in the safe mid-field. Sennasign is the only point that holds the apex line on both axes.

Throughput · y = trust · n = 7 platforms

Three laps,
three witnesses.

“We had a deal die on a Friday at 17:48 because we could not get a director’s signature in time. Sennasign was retained on Monday. Same scenario, six weeks later, sealed in 41 seconds.”

One stint.
One race.
