Use case — onboarding & KYC

Onboard a client in one verified channel

Identity verified once. Every KYC document collected and timestamped in one encrypted space.

What it is

One channel for the first weeks of a client relationship

Identity is verified once with PostNumber. KYC documents land in the place they will be needed later, not in an inbox.

Every exchange is timestamped, so the onboarding file is complete before the first mandate is signed.

Letro’s own AI, working inside your boundary

Private AI is the assistant built into Letro. It runs in an environment assigned to your organisation, bound to verified PostNumber identities. In onboarding, it turns your requirements into a workflow, asks each client for their documents in the same channel and flags what needs a second look. Your compliance team makes the final decision.

How it works

From invitation to an auditable client file

01

Invite the client

Send an invitation. The client installs Letro and verifies once with PostNumber.

02

Request the documents

Identity papers, contracts and forms arrive end-to-end encrypted in the same channel.

03

Review with the right people

Compliance, the relationship manager and legal work in one Workspace, scoped by role.

04

Keep the record

The timestamped delivery record stays with the file and exports when a regulator asks.

Why Letro

Four reasons onboarding belongs here

Verified from the first message

Every client holds a PostNumber issued after passport verification. You know who is on the other end.

One space, every document

Identity papers, contracts and compliance forms in one access-controlled channel instead of scattered attachments.

A record you can show a regulator

Delivery and receipt are timestamped and tamper-evident, with export when you need to evidence the process.

Cross-border without friction

Clients open Letro from their phone in any country. No portal accounts, no plugins, no setup.

Discuss your deployment model

Standard rollout, private infrastructure, or stricter residency and isolation. The evidential foundation is the same.
