From first audit to secure production.

We audit, stabilize, build and secure the systems marketplace and e-commerce businesses run on: marketplace integrations, SaaS products, internal tools and AI adoption. Start where your system is today.

Where we
come in.

Four capabilities behind every AI adoption engagement, from the first audit to the system that runs. Each is also available on its own, when one thing needs doing well.

Fig. 01DL-010

Audit

Consulting reviews of your marketplace operations, systems and data, with risks ranked and where AI pays off first.

Fig. 02DL-020

Stabilize

Incidents, broken integrations and AI-coded apps that fail in production, brought under control without stopping sales.

Fig. 03DL-030

Build

Custom software, AI agents and automation for commerce teams, built to scale and documented for handover.

Fig. 04DL-040

Secure

Security, data protection and marketplace policy compliance, so your accounts, listings and customer data stay safe.

Audit: understand the system

Stabilize: restore control

Build: engineer what comes next

Secure: verify and protect

Where engagements usually start

  1. 1.

    Inherited code or an AI-built app nobody fully understands: Audit.

  2. 2.

    Integrations or AI-coded apps that fail, slow down or cost too much: Stabilize.

  3. 3.

    A process, product or integration that doesn't exist yet: Build.

  4. 4.

    A security, data-protection or marketplace-policy requirement: Secure.

Audit, Stabilize, Build and Secure each act on the client's production system; inherited code enters through Audit, a new product through Build and a security or compliance need through Secure.findingsmapfixextendverifyINHERITED SYSTEMEntry pointNEW PRODUCTEntry pointSECURITY NEEDEntry pointAUDITMap / rank risksSTABILIZEFix / migrateBUILDIntegrate / extendSECUREVerify / approveYOUR SYSTEMIn production

Questions engineers ask us.

Q01How does DataDoe relate to Deltologic?

DataDoe is a Deltologic product: the Amazon data layer for AI agents, joining Seller Central, Vendor Central and Amazon Ads in one schema. Deltologic builds custom applications on it for teams that would rather not build on the data themselves.

Q02Who owns the software after you build it?

You do. Once the project is delivered, you legally own everything needed to run, maintain or extend it: source code, scripts, project files and executables.

Q03How do you price a project?

We give a transparent estimate based on our hourly rate, with scope, timeline and cost set out before work starts. You can pay in monthly instalments; larger projects usually start with a down payment.

Q04We have an idea but not the full feature list. Can you help define it?

Yes. We run workshops of 16 to 80 hours to work through the functionality with you and design the concept before anything is built.

Q05Our project is not about Amazon or marketplaces. Can you still help?

Yes. Marketplace commerce is our specialisation, but we also build for logistics, agriculture, automotive and other industries.

Not sure where to start?

Describe the system and the problem. We'll tell you which capability fits, and what the first step costs.
