Technology Built Around Your Business.
Build
Applications shaped around your process
AI-powered products, custom business software, CRM and SaaS platforms, websites and commerce systems — designed for how your business actually operates.
Every business has different processes, customers and challenges.
We don't believe in forcing businesses into one-size-fits-all software.
Redlitmus helps businesses design, develop and connect technology around their actual requirements.
We start with how the work is done today — including the exceptions nobody documents.
Architecture, data model and interface decided before code, and agreed with you.
Delivered in reviewable cycles on standard, well-supported technology you own.
Your systems, APIs and communication channels integrated into one working whole.
Measured, extended and improved as volume and requirements grow.
REQUIREMENT → ARCHITECTURE → SOFTWARE → INTEGRATION → SCALE
Six capability areas. Most engagements combine two or three — a CRM that also automates follow-up over WhatsApp, or a commerce platform wired into inventory and messaging.
We build practical AI solutions that improve operations, customer experiences and decision-making — grounded in your own data, with a human review path where one is needed.
const context = await retrieve(question, { topK: 6 });
// answer only from retrieved sources — never from memory
const answer = await generate({ question, context, cite: true });

From internal systems to customer-facing platforms, we design and develop software around the way your business operates.
We create CRM and SaaS platforms that help businesses manage customers, teams, workflows and operations from one connected system.
The screen a salesperson opens at 9:30am is designed first. If the CRM is not faster than the spreadsheet it replaces, it does not get used — and every report built on it becomes fiction.
We build fast, responsive and scalable websites designed around business goals — with a dedicated page per service so each one can rank on its own.
│ = target threshold
Most online stores do not fail at the product page. They fail in the operational half of the loop — stock, fulfilment and the update the customer never received.
Storefront + order consoleConnect systems, remove repetitive processes and create workflows that help teams work faster — while the conversations that need a person stay with a person.
Workflow builder
Every channel your customers use, connected to the systems that hold your data — so messages are triggered by real events and logged against the right customer.
Verified business profile, approved template messaging, a shared team inbox, chatbots and AI conversations, campaign sending and full CRM integration.
Application-to-person messaging for OTPs, transactional alerts and notifications, with sender ID handling, delivery reports and retry logic.
Rich business messaging with branded sender identity, images, carousels and suggested replies on supported Android devices, falling back to SMS where unsupported.
Business voice and calling services connected to your workflows, so calls are triggered, routed and recorded against the right record.
Direct inward dialling numbers for departments, campaigns, cities or teams — so you can tell where a call came from and route it correctly.
Number lookup and related telecom data services used to validate numbers before you spend money messaging them.
One shared inbox// Order shipped → notify the customer on their channel
await messaging.send({
to: customer.phone,
channel: "whatsapp", // falls back to SMS on failure
template: "order_status",
variables: { order: order.id, eta: order.eta },
});
// → delivery status is written back to the CRM record

Your business systems should work together.
We connect applications, APIs, platforms and communication services into one efficient ecosystem — with a defined owner for every field and monitoring that makes failure visible the same day.

Architecture
WorkshopSix stages. You see working software from stage four onwards, not at the end.
We understand your business, users and requirements.
Process mapping with the people doing the work, not only the brief from management.
We define the technology, architecture and workflow.
Data model, integrations, roles and delivery sequence agreed in writing.
We create intuitive interfaces and experiences.
The screens used most often are designed first and reviewed with real users.
We build scalable and secure technology.
Short cycles with a working build you can open and comment on.
We connect your systems, APIs and communication channels.
Tested against real credentials and real failure cases before go-live.
We support continuous improvement and growth.
Monitoring, training, handover documentation and a defined next phase.
YOU SEE WORKING SOFTWARE FROM STAGE 04 ONWARDS — NOT A DEMO AT THE END.
We are a technology partner, not a vendor selling one product. That shows up in how projects are scoped and what happens after launch.
The first conversation is about your process, your margins and your bottleneck — not our stack. If a packaged product solves it better than a custom build, we say so.
Your approval chain, pricing logic, roles and terminology are modelled as specified. Nobody has to work around a limitation in a product designed for a different business.
Systems are built with clean data models and documented APIs, so AI features attach to them later without a rewrite — and AI is only used where it beats a rule.
Requirement, architecture, interface, build, integration and launch handled by one team — so nothing is lost between a design agency and a development vendor.
We build software and the communication layer around it — WhatsApp, SMS, RCS, voice and APIs — so systems and customer channels are not separate projects.
Delivered in phases with a working system early, on standard technology you own, documented so any competent team can maintain it.
We are a technology partner, not a vendor selling one product. That shows up in how projects are scoped and what happens after launch.
The technology is similar. The process, the compliance and the moments that matter to a customer are not — which is where the design work actually happens.
We build on widely-adopted, well-documented technology so your system can be maintained by any competent team — including one that is not us. No proprietary framework, no vendor lock-in, no dependency on a single developer.
Access, credentials, handover
Source, documentation and every credential transfer to you at the end. Nothing stays locked to us.
These are the technologies we work with. We do not claim vendor certifications or partnerships we do not hold.
