LangChain development services
Build production LLM applications, AI agents and retrieval-augmented generation (RAG) pipelines with LangChain — orchestrating models, tools, memory and your data into reliable AI features.
LangChain is one of the most widely used frameworks for building applications on top of large language models, and Acqurio Tech uses it to ship production AI — RAG assistants grounded in your data, multi-step AI agents, and LLM features wired into your existing systems. We handle model orchestration, tool and API calling, memory, vector search and evaluation so your AI is reliable, not just a demo.
Whether you're adding a knowledge assistant, automating a workflow with agents, or connecting an LLM to your databases and tools, our engineers build it with the right guardrails, cost controls and observability — model-agnostic across OpenAI, Anthropic, Google and open-source models. Book a free discovery call to scope your first LLM feature.

What does LangChain development cost?
There's no fixed price for LangChain development — cost depends on scope, complexity and how much you build up front. We keep your risk low by starting with a small, high-value first phase.
Scope & features
A simple LangChain build costs far less than a complex, multi-feature platform. We scope must-haves first.
Complexity
Real-time, high-security or heavily-integrated LangChain work adds effort.
Integrations
Connecting to existing systems and third-party services adds scope, but saves manual work.
Team & timeline
Whether you need a fixed project, a dedicated team or staff augmentation changes cost and pace.

What our clients say
Real words from real clients — tap a quote to read the full case study.
“Acqurio Tech became our complete digital team — logo, website, SEO, content and social, all handled in one place. Within months we were ranking on the first page of Google and getting genuinely qualified leads, not just traffic. They're responsive, senior, and they actually move the needle.”
“Acqurio Tech rebuilt our entire online presence — a fast website on Azure, real-time tracking, quote tools, branding and SEO. We went from nowhere on Google to the first page across the US, UK, Canada and Australia, and from no online leads to over 100 enquiries a month — our business has roughly tripled since launch. They're responsive, technical, and they understand what a 24/7 courier business actually needs.”
“Acqurio Tech delivered a corporate website that finally matches our scale — every service vertical, every state we work in, our full project portfolio and an investor centre, all engineered for search. It's fast, genuinely premium, and it's helping us get found for the infrastructure work we do. A senior, dependable team.”
“Acqurio Tech took our whole IT modernisation off our plate. They moved 500+ GB of mail and data to Microsoft 365 without a minute of downtime, hardened it with MFA and endpoint protection, and rolled out firewalls, VPN and biometric access across our offices and construction sites. They're responsive, they genuinely know enterprise IT, and they've made our environment far more secure and reliable.”
“Acqurio Tech has been our complete digital team — they built our Shopify store, then rebuilt it headless so it's as fast and premium as our products, with a custom AI try-on and shade finder our customers love. They also run our SEO, social and ads. One senior team that genuinely gets our brand.”
“For the first time we run our whole FMCG operation — sales, purchase, manufacturing, inventory, HR and accounts — from one platform. Our 68-person field team lives in the mobile app, and I can see every rep, every beat and every order in real time on the dashboard. Acqurio Tech built exactly what we needed, on web, iOS and Android.”
