Vision Nexera

AI Development Services

Custom AI systems designed, built, and operated end to end, by a team that ships its own AI products, not just client decks.

Who this is for

The situations that bring people to us

AI is on the roadmap. Which 20% is real?

Every vendor says everything is possible. You need someone to separate the use cases that survive production from the ones that only survive demos, and to say so before you spend.

The prototype worked. Production didn't.

A notebook or no-code demo impressed everyone, then met real data, real latency budgets, and real users. Closing that gap is most of the actual engineering.

Your team builds software. LLM systems are a different discipline.

Retrieval quality, evaluation, cost control, and failure handling don't come from a weekend with API docs. Renting that experience is faster than growing it.

What we build

Concrete deliverables, not categories

AI products, zero to one

Full product builds where AI is the core: interface, backend, model orchestration, and infrastructure designed as one system.

How we build our own: NexeraHR

LLM-powered features

Assistants, extraction, summarization, and generation built into real products, with the caching, fallbacks, and observability that keep them dependable.

Retrieval & data foundations

Ingestion pipelines, embeddings, vector stores, and evaluation sets that make model output trustworthy on your data specifically.

Rescue & hardening

Inheriting a stalled AI build and getting it to production: an audit, an eval baseline, and a pragmatic path out.

How it works

How an AI system actually hangs together

Reference architecture: data and context feed retrieval, retrieval grounds models, models power the product surface, and operations closes the loop with evals and monitoringData & contextyour sourcesRetrievalgroundingModelsorchestrationProduct surfaceUI · APIOperationsevals · monitoringfeedback improves retrieval & prompts

Every dependable AI system we have shipped has the same skeleton. Your data and context get ingested and indexed; retrieval grounds the model in facts it can cite; an orchestration layer routes between models, tools, and fallbacks; the product surface is where users actually feel it; and operations (evaluation sets, tracing, cost and latency monitoring) is what keeps it true after launch.

Most AI failures happen at the seams between those layers, which is exactly where multi-vendor projects fall apart. We build and operate all five layers as one team, so nothing falls between contracts. And because we run our own products on this same skeleton, we feel the consequences of our architecture decisions before you do.

Decision framework

Generative AI, classic ML, or plain rules?

The most valuable call we make is often before any code: matching the problem to the cheapest technique that will actually survive production. Here is the framework we scope with.

ApproachWhere it winsWhat to watch
Generative AI (LLMs)Language, judgment under ambiguity, unstructured data, conversationNeeds grounding + evals; probabilistic by nature
Classic MLPrediction and scoring on structured, historical dataNeeds labeled data and time; less flexible, more measurable
Rules & automationDeterministic processes with clear logic: cheapest and most reliableBrittle where the real world is fuzzy

Proof, not promises

Our product

NexeraHR: an AI-powered ATS in production

The applicant tracking system we design, build, and operate for SMB hiring teams: resume parsing, matching, and screening workflows running on this exact architecture.

How we work

Four steps, each with an artifact

Artifacts beat adjectives. Every step of an engagement ends in something you can hold us to.

Step 1

Scoping call

Written scope & estimate

Thirty minutes on what you are building and why. You leave with a written scope, an honest estimate, and our view on whether AI is even the right tool.

Step 2

Architecture sprint

System design document

We design the system before we bill for building it: data flows, model choices, failure modes, and the success measure we will be judged against.

Step 3

Build in weekly demos

Working software, week one

Short cycles, working software every week, and decisions made in the open. You see progress in the product, not in status reports.

Step 4

Launch & run

Monitoring, evals & handover

We ship it, instrument it, and either run it with you or hand it over with documentation your team can actually operate from.

Most engagements start with a fixed-scope pilot: a written scope, a working system judged against a success measure we agree in advance, and a clean decision point. From there, work continues as a retained build with weekly demos.

Our pricing philosophy over a rate card: honest scoping, written assumptions, no surprise change orders. We will tell you when AI is the wrong tool, because our credibility is worth more than one project.

Straight answers

Questions buyers actually ask

What does an AI development company actually do?

It designs, builds, and operates software where machine intelligence does part of the work: from scoping which use cases are viable, through data and model engineering, to shipping and monitoring the product. At Vision Nexera that means end-to-end delivery: interface, backend, model layer, and infrastructure, handled by one team.

How do you decide whether my use case is viable?

In the scoping call and architecture sprint we test three things: is the data available and clean enough, can success be measured, and can the business tolerate the error rate. If any answer is no, we say so. Sometimes the right recommendation is rules or classic automation, not AI.

How much does custom AI development cost?

Scoped pilots typically start in the low five figures (USD); full product builds run higher depending on integrations, data work, and the reliability bar. We quote fixed scopes with written assumptions rather than open-ended hourly estimates, so the number you approve is the number you pay.

How do you handle hallucinations and reliability?

Grounding through retrieval over your data, constrained tool use, evaluation sets that run on every change, and human-in-the-loop gates where mistakes are costly. Reliability is engineered, not prompted. It is most of the difference between a demo and a product.

Who owns the code?

You do. Code, prompts, pipelines, and documentation transfer on payment, and we build on your accounts and infrastructure wherever possible, so there is no hostage risk and no forced dependency on us.
