We build the AI agents and models behind ambitious products.
We are a boutique studio crafting custom AI agents, domain-specific models, and the software around them.
We partner with teams who need real AI capability to empower their business. Every engagement pairs research-grade model work with the engineering to ship it, so what we build actually runs in your product.
AI has stopped being a bet on the future. It's how competitive businesses run today.
The question is no longer whether to adopt AI, but how deliberately you do it. Done well, it compounds, freeing your people, sharpening your decisions, and widening the gap between you and everyone still doing it by hand.
Speed becomes a habit
Work that used to take a team days, research, drafting, analysis, support, collapses into minutes, so your people spend their time on judgment, not busywork.
Scale without adding headcount
Well-built agents handle the repetitive volume around the clock, letting a small team operate like a much larger one.
Your data becomes an edge
The knowledge already sitting in your business, documents, tickets, transactions, turns into models and assistants no competitor can copy.
The gap is widening
Your customers and rivals are already adopting it. Every quarter you wait, catching up gets more expensive and the lead in front of you gets longer.
Deep AI capability, engineered to ship.
Custom AI Agent Development
We design and build production AI agents around your real workflows, planning, tool use, memory, and guardrails included. From a single focused assistant to multi-agent systems, we own the whole loop: architecture, evals, and the integration work to put them in front of users.
Domain-Specific Model Training
When off-the-shelf models fall short, we fine-tune and train for your domain, finance, legal, logistics, oil & gas, or something more specialised. We build the datasets, run the training, and hold the work to evaluation criteria that reflect how it will actually be used.
Web & App Development
AI is only useful once people can use it. We build the surfaces around your models and agents, web apps, dashboards, APIs, and the infrastructure underneath, with the same team that built the intelligence, so nothing gets lost in translation.
Advisory & Team Enablement
For teams building in-house, we run intensive workshops and embedded advisory, from architecture reviews to hands-on sessions on building, evaluating, and shipping agents and models responsibly.
How we work
Discover
We map the problem, your data, and what success actually looks like before writing a line of code.
Prototype
A working proof-of-concept fast, so we can measure what matters and de-risk the hard parts early.
Build
Production engineering, evaluation, and hardening, with you in the loop the whole way.
Deploy
We ship into your infrastructure and stay on for monitoring, tuning, and support.
Selected work
MingAI
We trained a domain-specific model for metaphysics and built the AI agents around it, plus the full product surface, a web application and native Android and iOS apps.
Nanimom
We designed and built the ecommerce storefront for this organic baby & toddler meal brand, with AI capabilities built in, from personalised product discovery to an assistant that helps parents choose the right meals.
Gafung Petroleum
An AI workflow to enhance inventory and cost management for this oil & gas firm, alongside the web presence that surfaces it to their team.
AçaiFlow
Web design and a food-ordering system for this wholefood bowl brand, a bowl builder and online ordering flow, with AI woven through the experience.
A small studio for serious AI work.
Cortexum is a Singapore-based studio building custom AI agents, domain-specific models, and the software that carries them into production.
We stay deliberately small. Every project is run by the senior people who do the work, no layers, no handoffs. That means research-grade modelling and production engineering under one roof, moving at the pace a small team can.
We work with founders, enterprises, and public-sector teams who need AI that holds up in the real world, measured, auditable, and built to last beyond the demo.
