LLM development company in Jerusalem
Senior engineers who move at startup speed, plug into your codebase and work most of your day.
Clarigo Infotech is an LLM development company that builds custom applications on large language models such as OpenAI GPT, Anthropic Claude, Google Gemini and open-source models like Llama. We design the prompts, retrieval, tools and guardrails, connect the model to your data and systems, and run it in production with monitoring, evaluation and cost control.
Israeli startups and tech companies most often hire us for AI and LLM products, SaaS platforms and extra senior engineering capacity alongside their own team.

Speed, depth and direct communication
Israeli teams move fast and expect engineers who can keep up: senior, hands-on and direct. We work as an extension of your team, not an agency layer.
Senior engineers only
People who have shipped this before and can pick up an existing codebase in days.
Your processes, your tools
Your Git flow, your sprint rhythm, your Slack, including Sunday-to-Thursday schedules when agreed.
Straight answers
Direct feedback on scope, risks and trade-offs, so decisions happen quickly.
AI and deep tech
LLM apps, agents, RAG and computer vision built for production, not demos.
What we build with LLMs
Custom LLM applications
Assistants, copilots and internal tools built around your workflows, not a generic chat window.
LLM integration
Add GPT, Claude or Gemini to your existing product through secure, well-tested APIs.
Open-source and private models
Deploy Llama and other open models on your own cloud when data must stay in-house.
Fine-tuning and evaluation
Tune models on your examples and measure accuracy with test sets before and after launch.
Guardrails and safety
Input and output filtering, PII masking, grounding checks and human review where needed.
Cost and latency optimisation
Model routing, caching and prompt design that keep responses fast and bills predictable.
How we approach LLM development
Choosing the right model
There is no single best model. We compare OpenAI, Claude, Gemini and open-source options on your real tasks for accuracy, speed, cost and data handling, and design the app so the model can be swapped later without a rewrite.
Grounded in your data
Most business value comes from connecting the model to your documents, databases and tools. We use retrieval (RAG), function calling and agents so answers come from your information and actions happen in your systems.
Built for production, not demos
We add evaluation test sets, logging, monitoring, rate limits, fallbacks and cost alerts from day one, so the app keeps working well after launch and you can see exactly what it is doing.
Security and compliance
Data minimisation, encryption, access control and providers configured not to train on your data. For healthcare we build to HIPAA requirements with BAAs in place for any service that touches PHI.
How we work with Jerusalem clients
Time-zone overlap
Israel is only two and a half to three and a half hours behind India, so our working days overlap for most of the day, including Sunday-to-Thursday schedules when agreed.
The Israeli Protection of Privacy Law and Data Security Regulations
We design products to the Protection of Privacy Law and the Privacy Protection (Data Security) Regulations: access controls, encryption, logging and data kept in the cloud region you choose. We sign NDAs and data agreements before work starts.
Billing
Invoices in Israeli new shekels (ILS) or US dollars. Typical senior rates are $25 to $49 (USD) per hour, or a fixed price for a defined scope.
Industries we work with in Jerusalem
Jerusalem's healthtech, edtech and deep-tech companies work with us on web and mobile products, AI features and the platforms that support them.
Cybersecurity
Security startups need polished SaaS dashboards and fast releases. We build AI agents, assistants and automation around these workflows.
Fintech
Payments and insurtech firms build global-first products. AI here usually means faster reporting, fewer manual steps and better customer replies.
Healthtech
Digital health firms combine medical data with AI. We start with one costly process and automate it end to end.
Agritech and water tech
Irrigation and water innovators sell IoT platforms abroad. We build AI agents, assistants and automation around these workflows.

Where will our data be hosted?+
Usually in AWS Israel (Tel Aviv) and Google Cloud me-west1 (Tel Aviv), or wherever your data rules require. Everything runs in your own cloud account, so you stay in control.
Do you support WhatsApp?+
Yes. Customers in Jerusalem often prefer WhatsApp and Telegram and LinkedIn, so we connect chatbots, notifications and support flows to them.
Which LLM should we use: GPT, Claude, Gemini or open source?+
It depends on your task, data rules and budget. We test the options on your real examples and recommend the best fit, and we build so you can switch models later.
Can you keep our data private?+
Yes. We use providers configured not to retain or train on your data, mask sensitive fields, and can deploy open-source models on your own cloud when data must not leave your environment.
