AI-native software studio

Software at agent speed.

ERST puts AI agents to work in its own delivery pipeline and inside client products. Architecture and the final call always stay with engineers.

01 / Approach

Speed comes from agents; judgment comes from people. Agents plan, write code and run tests. Engineers design the architecture, approve each step and own the result. The outcome: software that reaches production sooner.

02 / What we do

From software to the server.

A

AI agents

Sales, support, appointment and operations agents. They work with WhatsApp, the CRM and internal systems, and hand over to a person at critical steps.

B

Company software

Company applications, panels, CRM and ERP. Roles, APIs and the data model. Built properly once, used for years.

C

Web and interface

A new site, and development of the one already live. Fast, multilingual, and readable by search engines.

All services

06 / Blog

What we learned in the field.

Don’t leave WhatsApp on one phone.

When WhatsApp lives on one employee’s phone, customer conversations get lost. A shared inbox fixes that.

QR is quick to start. Bulk messaging needs another route.

Connecting WhatsApp with a QR code and sending from a Meta-verified line are not the same thing.

An exchange office website is a separate product.

A site that shows rates, takes orders and tracks them is not just a tab inside the CRM.
