Enterprise custom development

Build what your organisation is missing, not the years of foundation underneath it

Enterprises that decide to build their own email marketing, SMS, CRM and AI agent platform find that the foundation alone takes years: permissions, consent, deliverability, audit logs and localisation. That foundation already exists here and is tested. A local development team builds only what is specific to you, working side by side with your own developers.

How long does it take to build a marketing automation platform in-house?

This is the path when you start from zero, against building on an existing base. The years are the order of magnitude of an in-house build, not a commitment for your project, but the order of the work never changes.

  1. Year 1

    Foundation

    Database, permissions, department isolation, sending and deliverability, consent and unsubscribe handling.

  2. Year 2

    Channels

    SMS, WhatsApp on the official API, templates, forms, landing pages and reporting.

  3. Year 3

    Automation and AI

    Behaviour-triggered journeys, CRM, AI agents, audit logs and a connection layer for AI assistants.

  4. On our platform

    Only what is yours

    The foundation exists and is tested. Development goes on your integrations and your processes.

What your team will not have to write

More than 9,000 automated tests already run on this foundation before a change is merged.

Permissions and isolation

Separation between departments, brands and clients enforced in the database, with an audit entry for every action by a person or an AI agent.

Every channel from one list

Email, SMS and WhatsApp with a documented consent record per recipient and an unsubscribe that applies across all channels.

CRM and automation with versions

Contacts, deals, tickets, projects and workflows with versioning, simulation before activation and rollback.

AI agents with limits

Agents that answer from your content, open leads and hand over to people, with only the permissions you grant and a human approving every send.

Three languages, including right-to-left

English, Hebrew and Spanish across the interface, so a multinational rollout does not start with a translation project.

An MCP layer for AI assistants

Every capability, including the extensions built for you, can be operated by an AI assistant your organisation approves.

The campaign editor is already built. Your project starts from here, not from an empty repository.

How does a project with a local team work?

  1. 1

    Specify what is missing

    We sit with your business and technical teams and write down what the platform must do that it does not do yet: an ERP integration, an internal approval flow, a specific report, or an agent for your industry.

  2. 2

    Build as an extension, not a fork

    Development lands as an extension of the platform rather than a separate copy of it, so security fixes and new releases keep reaching you without breaking what was built.

  3. 3

    Your developers inside the project

    Your engineers work next to ours, see the code, the tests and the documentation, and by the end know how to maintain and extend it on their own.

  4. 4

    Delivered with tests

    Every capability ships with automated tests, an interface in English, Hebrew and Spanish, and documentation. Nothing untested counts as done.

Why a local team saves more than time

A marketing and CRM project in a large organisation rarely fails in the code. It fails in the gap between what the business needs and what a vendor in another time zone understood. A local team knows the anti-spam and privacy rules you operate under, your accessibility requirements, your SMS providers and the way your organisation approves decisions. It sits in the meetings, answers in your working hours and speaks the language of the people who will use the system.

The largest saving is the foundation. A serious marketing automation platform needs consent management that survives legal review, deliverability that keeps mail out of spam, isolation between departments, audit logs and a complete multilingual interface. All of that already exists and is covered by tests, so your development budget goes to what actually sets your organisation apart.

And when the project ends, the work does not disappear into a vendor. Extensions are documented, tested on every release, and reachable by AI assistants through the platform's MCP layer. If data may not leave your network, the same extensions run in an on-premise installation.

When building on the platform is the wrong call

Your product is the email platform

If you are building an email platform to resell as your own product, another vendor's foundation will limit you exactly where you want to compete. Build it yourself.

You need one small integration

A single connection to an external CRM or Zapier does not need a development project. It usually exists already as a signed webhook or a ready integration, and we will show you how to set it up.

Nobody owns the decisions

A development project needs one accountable owner who approves requirements and accepts the result. Without one, requirements change every week and the project drags, whatever the team.
