Built for teams at every stage of their AI journey.

Where does AI fit in your business?

01From idea to production

You want AI in your product and need a team that has done this before.

Your board is asking, competitors are moving, the use case is real. We handle the data work, model decisions, and engineering so your first AI project ships well.


A working AI feature in production, with evals, guardrails, and a cost ceiling you can plan against.

02Prototype to production

Your AI pilot proved the value; now it needs to run at scale.

Predictable latency, optimized inference cost, monitoring, graceful edge-case handling. This is where AI projects become AI systems.


Production-hardened AI with monitoring, fallback logic, and inference costs inside budget.

03AI at scale

You're rolling out AI across teams and want to do it right.

Multiple teams, multiple use cases, real need for consistency, security, and governance. We build the platform layer, not just features.


An AI platform built into your tooling, with a compliance posture your CISO will sign off on.

Before you commit to a path, choose the right one.

Custom AI build vs API integration vs off-the-shelf AI SaaS

Each path has genuine strengths; the right choice depends on your use case, volume, and goals. Here's how the three compare across the dimensions that matter most twelve months in. Zethic builds the first two; we'll tell you honestly when the third is the right call.

What matters
Recommended Custom build
Common alternative Off-the-shelf SaaS
Other path Low-code platform
Time to first value 10 to 16 weeks to a production system built for you Days to a working prototype, fastest path to validation Hours to start, within the vendor's feature set
Staying current with frontier models You control the upgrade cycle and timing Automatic new releases reach you immediately Vendor manages upgrades on their schedule
Fit to your domain Built around your data and edge cases, highest accuracy ceiling General-purpose, shaped by your prompts Pre-built workflows, fastest to adopt as-is
Long-term cost (3 yrs) Flat after launch, inference optimized for your volume Pay-as-you-go scales smoothly at low to medium volume Predictable per-seat pricing at smaller sizes
Maintenance Full control, SLA-backed if you want Minimal, provider handles model ops Fully managed by the vendor
Data ownership Your models, pipeline, embeddings Governed by the provider's policies Managed within the vendor's platform
Compliance posture Your audit trail, controls, and governance Inherits the provider's certifications Inherits the platform's certifications
Flexibility over time Codebase evolves with your business Easy to switch providers Tied to the vendor's roadmap
Pick custom when
  • Accuracy needs exceed general-purpose models.
  • Volume makes a one-time build cheaper than per-token pricing within 18 months.
  • Data residency or regulation calls for infrastructure you control.
  • AI is the product itself, and governance needs full audit trails.

AI inside our delivery, not just in the product.

How we ship AI faster, with AI in the loop

AI is a tool in our delivery pipeline as much as it is the thing we build for you. Here is how it changes the work, the speed, and the quality of what we hand over.

Schedule a call

Evals and guardrails from day one

Every AI feature ships with a test harness, golden datasets, and live eval dashboards. No silent regressions when a model version flips or a prompt changes.

  • LangSmith
  • Promptfoo
  • Braintrust
Regressions caught pre-release

AI-assisted coding with guardrails

Senior engineers pair with Cursor and Copilot where it earns its keep, with a typed style guide and review gates so generated code clears the same bar as hand-written.

  • Cursor
  • GitHub Copilot
  • Claude Code
~30% faster feature delivery

Cost-aware model routing

Token budgets, caching, batching, and right-sized model selection are designed in before launch, so inference cost scales with value rather than usage curves.

  • OpenRouter
  • LiteLLM
  • Semantic cache
Inference cost inside budget

AI-assisted research and discovery

Faster use-case teardowns, data-readiness audits, and architecture options. You get more shape on the problem in the first two weeks, not the first two months.

  • Claude
  • Perplexity
  • Notion AI
Discovery in 1 to 2 weeks

Every line of AI-generated code is reviewed by a senior engineer and ships under your IP, the same as anything else we write. No model-generated code goes to production unattended.

Why teams choose Zethic to build AI

Senior AI Engineers, Direct Access

The pod that scopes the work is the pod that ships it. No outsourcing, no junior teams, no account managers sitting between you and the engineers doing the build. Clients in the US, UK, Middle East, and Southeast Asia receive the same engineering quality they would expect from a top London or New York firm, at India-based pricing.

Evals Before Everything

Eval framework, golden datasets, and acceptance criteria are defined before the first model call. Test harness and live eval dashboards catch regressions pre-release. Where precision matters most, we add human-in-the-loop checkpoints.

Cost-Optimized Inference

Token budgets, model selection, caching, and batching are designed from day one. We treat inference cost as a first-class engineering constraint, so cost scales with value, not with usage curves.

Full Code and Model Ownership

Your models, embeddings, pipelines, training data, and IP are yours to run, fork, and extend forever. Everything lives in your repo and cloud account. You stay free to switch providers, swap models, or take the system in-house at any time.

Frequently Asked Questions

The full process of building, integrating, and deploying AI systems: consulting, data pipelines, model development and fine-tuning, integration, and post-launch monitoring.

We start by mapping what you already have. Most projects need some extraction, cleaning, labeling, or enrichment, and we scope that work transparently up front, usually 15 to 30% of the budget. Discovery gives you a clear picture of what you have, what you need, and the fastest path between them.

Grounding and guardrails. RAG ties answers to your actual sources, eval suites verify quality before release, and every system ships with fallback logic and confidence thresholds. Where precision matters most, we add human-in-the-loop checkpoints.

We're model-agnostic by design. We work with OpenAI, Anthropic, open-source models like LLaMA and Mistral, and your own fine-tuned variants, choosing whichever meets your accuracy bar and budget. You stay free to switch as the market evolves.

We architect so models are swappable. Prompt versioning, an eval harness, and a clean model interface let us benchmark each new release against your golden datasets and adopt it when it improves your metrics, no rewrite required.

You do, fully: models, weights, embeddings, training data, and pipelines live in your repo and cloud account.

Eval frameworks, bias testing, adversarial red-teaming, drift monitoring; architected to SOC 2, ISO 27001, GDPR, DPDP, and HIPAA.

We treat inference cost as a first-class engineering constraint from day one: right-sized model selection, caching, batching, and token budgets are designed in before launch. As usage grows, we tune model routing and infrastructure so cost scales with value.

Cost transparency, before the call.

What actually moves the number

Get a real scope band
01

Data readiness

How much extraction, cleaning, labeling, and enrichment your data needs before a model can use it, usually 15 to 30% of the work.

02

Accuracy bar

The higher the precision requirement, the more eval work, fine-tuning, and human-in-the-loop checkpoints the system needs.

03

Integrations

Every external system and data source (CRM, ERP, knowledge base, identity) adds discovery, contract testing, and failure handling.

04

Compliance posture

SOC 2, HIPAA, RBI, DPDP, and similar add architecture constraints, audit work, PII handling, and pre-launch reviews.

05

Inference volume

Expected request volume drives model selection, caching, and infrastructure, the difference between a flat cost and a runaway one.

Bands include data work, engineering, evals, MLOps, and PM. Model and inference fees, hosting, and third-party licenses are billed at cost.
