Antegrate helps companies untangle, modernize and extend business-critical software without blindly rewriting everything.

Start a conversation How we assess a system

Paths a change must travel

Software becomes expensive when a change has to cross too many boundaries.

Most systems that need this work are not failing. They are processing orders, serving customers and generating revenue, and have been for years. Nothing is on fire. What changed is the price of change — and that transition is almost invisible until a specific request makes it obvious.

You are probably somewhere here

A change that sounds smallcomes back estimated in quarters
A partner, market or regulationhas nowhere clean to go
Integrations fail quietlyand customers find them first
Deployment is manualand one person can run it
Systems that should talk don’tso people move the data by hand
A rewrite has been proposedand everyone is quietly terrified

None of these is a crisis. That is precisely why they get deferred — and deferral is how a system that merely became expensive to change eventually becomes one that cannot change at all.

We diagnose the problem and then build the solution.

Strategy firms will analyse your system and hand you a document. Development shops will build what you specify. Neither is much use when the actual problem is that you know what outcome the business needs and it is not obvious what should be built.

Antegrate is principal-led. Technical ownership stays with Dorian Ben Haim throughout the engagement — architecture, the significant technical decisions, implementation oversight and acceptance. That accountability is not delegated.

Three kinds of work

Legacy Modernization

The system still works. Changing it has become slow, risky and expensive.

Architecture remediation, incremental replacement, deployment and infrastructure modernization — without the rewrite that would freeze delivery for two years.

What this involves

Systems Integration

Your systems don’t talk to each other, or they do and it breaks.

APIs, third-party integrations, cross-system workflows, data movement, and the automation of processes that currently move through people.

What this involves

Custom Business Systems

What the business needs does not exist as a product you can buy.

Internal platforms, operational applications, portals, APIs and purpose-built software around the processes that make you different.

What this involves

A single problem can cross more than one of these. Systems that have become hard to change are rarely broken in a single layer, which is the main reason a specialist review tends to recommend replacing everything.

The work is the proof

Read a complete assessment.

Every section, at the depth we write to. A seven-year-old .NET order platform, three brittle integrations, a manual release process, and a partner integration priced at five months against a six-week expectation.

It concludes: do not rewrite the platform. Then it prices the alternatives against each other and recommends against several pieces of work that could have been sold.

The company is invented. The standard of work is not.

Technical Systems Assessment

Example

Northwind Industrial Supply — Order Management Platform

Why does the Meridian partner integration cost five to seven months when it was expected to take six to eight weeks? The estimate is approximately correct, and the reason it is correct is the finding of this assessment.

Patch into existing pipeline	$66K
Seam + Meridian + stabilization	$119K
Full platform rewrite	$1.65M–$3.4M

Recommendation: do not rewrite the platform. Build the integration boundary that should have existed, and deliver Meridian through it.

How an engagement works

A conversation about the system, not a proposal: Describe what you have and what is making it difficult to change. We will tell you whether this is work we are the right firm for — including when it is not.
Technical Systems Assessment: A bounded diagnosis with a written, decision-grade output that works for both a CTO and a CFO. It carries no implementation credit, because it is meant to be worth its price on its own.
Implementation: Follows the plan the assessment produced, in phases with defined scope. Dorian remains accountable for architecture, significant technical decisions and acceptance throughout.
Where the assessment is not the right instrument, we skip it: If the problem is well understood and scoped, there is no reason to pay for a diagnosis of something you already know.

What the assessment includes

When we are the wrong firm

We would rather tell you now than three emails from now.

You need hands on a backlog
Antegrate takes ownership of a problem, a system or an outcome — not a seat on your board.
You are building a new product from zero
Greenfield with no existing system is a different discipline, and there are firms better suited to it.
You need two applications connected and nothing more
Real work, wrong firm. It sits below the level where this makes economic sense for either side.
You need guaranteed round-the-clock response
We are deliberately small and will not sell response-time commitments we cannot reliably honour.
You are running a formal enterprise procurement
Vendor onboarding, security questionnaire cycles and insurance thresholds carry an overhead a practice this size cannot absorb honestly.
Lowest price is the primary decision criterion
There will almost always be a cheaper quote. If minimizing upfront cost matters more than technical ownership, Antegrate is unlikely to be the right fit.

Tell us about your system

Not a sales call. Describe what you have, what is making it difficult to change, and roughly what you are working with commercially. We will tell you whether there is a sensible engagement here — and if there isn’t, we will say so.
