Own the AI layer running on your SAP. Every agent you add ships faster than the last.
Most enterprises don't need another AI product. They need AI running as infrastructure on their SAP, so every new use case is just logic, not a new integration project. We design that layer with your team and install it inside your environment: your choice of models, swappable anytime, no subscription, no black box. You own it, end to end.
The problem
You've seen this stall before. It was your pilot.
These aren't abstract industry figures. They describe the project you already ran, or watched a peer run: a working demo, an executive sponsor, and a budget line that never reached production.
0%
of enterprise GenAI pilots deliver zero measurable return — most stalling after a demo everyone in the room had already approved.
0%
of CIOs say traceability and explainability gaps have already delayed or stopped AI projects from reaching production.
0%
of CIOs said their AI budget would be cut or frozen without proven value by mid-2026. That deadline has passed — and a pilot with zero return counts as no value at all.
A pilot that can't answer “why” stops at the wall — a system with readable rules and logs walks through
None of that is bad luck. It's what happens when a black box that can't explain itself meets an enterprise that has to audit every answer.
Rent vs. own
You don't have an AI problem. You have a rental problem.
Every SaaS AI tool and most systems-integrator contracts are the same deal: your data moves to someone else's cloud, the model is whichever one they picked, and the bill renews every month whether the thing works or not. That is why 95% of enterprise GenAI pilots never show a measurable return - a rented black box nobody inside your company can open, audit, or extend was never going to carry a core process.
Own the layer and none of that applies. It's installed inside your own environment, on-premise or in your cloud, and wired into your S/4HANA or ECC data, so your records stay where they already live and there's nothing new to re-approve every time you add a capability. The first integration is the expensive one. Every one after it gets reused, so each new use case ships faster and costs less than the one before it.
Renting AI
- Your data moves through the vendor's cloud, on the vendor's terms.
- The vendor picks the model. You live with it.
- A generic black box, retrofitted onto your SAP system.
- The vendor holds the keys. You hold the invoice, every month.
- Every new use case means a new contract and a new review.
Owning the layer
- The layer runs inside your perimeter, on-premise or in your cloud. Never ours.
- You pick the model, cloud or local. Swap it anytime.
- Agents built around your highest-value SAP processes - logic your team can read.
- Your own team holds the keys and runs it. No subscription.
- Every new use case reuses what's already built, faster and cheaper than the last.
What we install
One AI layer, installed inside your environment, wired straight into S/4HANA or ECC.
Requests start messy: an email, a ticket, a spreadsheet, someone typing a question in plain language. The layer reads the request, checks it against your SAP data and your business rules, then writes back a clean transaction, a posted document, an approved step, an updated record, through the same interfaces your own developers already use. No schema changes, no touching the core.
And it's deliberately not pure AI. Deterministic logic and LLM reasoning split the work: a rules engine owns the steps that must always be exact, the model handles the unstructured parts, confidence scoring decides when its output can be trusted, and a human approves anything below that bar. That mix is what keeps precision high and running costs low - and none of it is a black box: your team can read every rule and every log. We design that logic with your team first. Then it runs on your infrastructure, next to the SAP system it was built to read.
Installed inside your environment
Not a hosted SaaS tenant. The layer runs on your infrastructure, on-premise or in your cloud, next to the SAP system it talks to.
You own it, end to end
The pipelines, the agent logic, the interfaces: all of it stays yours after go-live. No subscription, no per-seat pricing, no vendor holding the keys.
Wired directly into SAP
Reads and writes at the transaction level in S/4HANA or ECC. No off-the-shelf connector: we develop the SAP side of the integration ourselves, against your actual landscape.
Any LLM, swapped without rework
The connections to SAP stay in place while the model underneath changes: a cloud provider, a local model behind your firewall, or whatever you choose next year.
No lock-in
Swap the model. The work doesn't stop.
Change providers, or point the layer at a local model behind your firewall, without touching the agents, the pipeline, or a single SAP interface.
The compounding
The first agent builds the interfaces. Every one after it just plugs in.
Agent one has nothing to connect to yet, so it spends its three months wiring governed interfaces into SAP, Orders, Invoices, whatever the process touches. Those interfaces are yours the moment they exist. Agent two needs one of them again, reuses it instantly, and only builds what's actually new: weeks, not months. Agent three needs nothing new at all. Both interfaces it touches already exist, so there's no wiring left, only logic to ship: days. And every agent, first or tenth, inherits the layer's built-ins, human-in-the-loop approval, confidence scoring, the rules engine, so none of that is ever built twice either. Watch it happen below. The work doesn't repeat. It stacks.
The tenth agent won't cost what the first one did. The interfaces were the expensive part, and because you own them, you only build each one once.
The offer
The layer installed. Your first use case live in production.3 months.
Timeline
3 months
One-time implementation. No subscription, no license fee - the layer is yours outright.
Guarantee
Miss it, we work free
If the layer isn't installed and your first use case isn't live in 3 months, we keep working at no charge until both are done.
Deliverable & value
The layer installed inside your own environment, wired into your S/4HANA or ECC data - we develop the SAP side of the integration ourselves, against your actual landscape. One production use case live on top of it, chosen to move a number you already report to the board: revenue, OPEX, or risk. And every interface built along the way stays yours, reused by each use case after it.
“You own the layer. It runs on your infrastructure. The number you report is one you can defend.”
The proving ground
Proven at a regulated German bank, not in a lab
Our first customer for this layer was a regulated German bank, and the architecture passed every security check there before go-live. That's the one thing we'll say about security. The argument that matters day to day is flexibility: you own the layer, you pick the models and swap them when you want, and nothing in it is a black box your own team can't open and extend.
SAP
Deep engineering fluency in S/4HANA and ECC - we develop the SAP side of every integration ourselves, down to the transactions that run the business.
AI / ML
Agents that pair a rules engine with LLM reasoning - confidence scoring and human-in-the-loop included - built to run daily operations, not stall after the demo.
Data
Data pipelines and governance designed in from the start, not bolted on after the first audit finding.
Architecture
Yours end to end: no black box, no vendor dependency, nothing your own team can't operate and extend without us.

Who this is not for
Not everyone reading this should book the call.
If any of this is true, we'll save you the 30 minutes.
You're not running SAP S/4HANA or ECC. The layer itself isn't SAP-only, but SAP is where we build the ERP side ourselves. If your core is something else, we're probably not your fastest path.
You want a strategy deck and nothing built. We do help with strategy - but always on the way to working software, with a use case live in 3 months.
You'd rather rent a tool than own your stack. Everything we build runs in your environment and stays yours. If a subscription you can cancel is the goal, a SaaS vendor is the better call.
NexIT is for teams that have already decided to own their AI layer end to end - not the ones still shopping for a vendor to rent one from.
