Need custom software but getting vague estimates and time-and-materials proposals that shift as scope evolves?
Inherited a legacy system that's blocking growth and needs modernisation without a full rewrite?
Software Development Services
Software development is broad. The right build for a startup validating a market looks nothing like the right build for an enterprise modernising a legacy system -- and both look nothing like building a SaaS product for scale.
We build custom software, SaaS platforms, enterprise systems, and product MVPs. Fixed cost, clear scope, source code ownership. No surprise invoices when requirements sharpen.
Custom software, SaaS platforms, enterprise systems, and product MVPs
Web applications, API development, CRM/ERP, marketplaces, and on-demand platforms
AI-integrated products -- not just traditional software
Fixed-cost delivery in 12-14 week cycles with working software every two weeks
RaftLabs is a software development company that builds custom software, SaaS platforms, enterprise applications, MVPs, and AI-integrated products for startups, scale-ups, and enterprises. We've shipped 100+ products across 24+ industries. Our delivery model is fixed-cost with clear scope -- not time-and-materials. Working software is delivered every two weeks throughout the build. All clients own their source code.
What you're actually paying for
A software development project doesn't fail because the engineers can't write code. It fails because the scope was unclear, the architecture wasn't designed for the actual use case, or the delivery process didn't surface problems early enough to fix them.
We invest the upfront time to get scope and architecture right. Then we deliver visibly -- working software every two weeks, not a reveal at the end.
What we build
Custom software and SaaS platforms
Business software built for your specific workflows -- not adapted from a generic template. Multi-tenant SaaS platforms, custom CRM and ERP systems, internal tools, and operational software that your team actually uses. Starting from business requirements, not a feature checklist. See Custom Software Development and SaaS Development.
Product MVPs and startup builds
Fast, focused first versions that test your core business hypothesis at production quality. We scope the right MVP -- the minimum version that validates the market, not the minimum version that's technically functional but unusable. 12-14 week delivery. See MVP Development and Startup Software Development.
Enterprise software development
Large-scale software for established organisations: enterprise resource planning, complex workflow systems, data platforms, and integration projects connecting multiple systems. Experience with enterprise procurement, compliance requirements, and complex stakeholder environments. See Enterprise Software Development.
Web applications and API development
Full-stack web applications: customer-facing products, internal tools, data dashboards, and admin systems. REST and GraphQL API development for first-party and third-party integrations. API-first architecture for products that need to support mobile, web, and external integrations. See Web Application Development and API Development.
Marketplace and on-demand platforms
Two-sided and multi-sided marketplace platforms: buyer and seller matching, listing management, payment processing with Stripe Connect split payments, review systems, and search and discovery. On-demand platforms with real-time dispatch, driver/provider apps, and customer-facing booking. See Marketplace Development and On-Demand App Development.
Legacy modernisation
Migrating legacy systems to modern architecture without stopping the business. Strangler fig pattern for incremental migration, API layer over existing systems, database modernisation, and full rewrites where incremental migration isn't viable. We assess the legacy system first -- the modernisation approach depends on what you're starting from. See Legacy Modernisation and Software Modernisation.

Frequently asked questions
Custom business software (CRM, ERP, HRMS, workflow tools), SaaS platforms (multi-tenant web applications sold to other businesses), product MVPs for startups validating a market, enterprise software modernisation (migrating legacy systems to modern architecture), web applications, API development and integration, marketplace platforms (two-sided and multi-sided), on-demand platforms, e-commerce, and AI-integrated software. We don't build commodity projects -- if a no-code or low-code tool solves the problem, we'll tell you.
We work on fixed cost, not time-and-materials. We scope the project with you, agree on what's included, and give you a fixed price for that scope. If scope changes, we discuss it and adjust together. We don't do open-ended billing that shifts the cost risk to you. Project pricing varies by complexity -- see our individual service pages for typical ranges. An MVP with 4-5 core features typically runs $35,000--$70,000. A full SaaS platform runs $70,000--$200,000+. We provide a proposal after a discovery session.
Both, but the engagement looks different. Startups: we help you scope the right MVP -- the minimum version that tests your core hypothesis -- and build it to production quality in a single cycle. Speed to market and capital efficiency matter most. Enterprises: we engage on larger projects -- software modernisation, new internal systems, or greenfield product development where you have existing infrastructure to integrate with. We can work within your procurement and compliance processes.
Discovery (1-2 weeks): scope definition, architecture planning, and delivery milestones agreed. Design: UX/UI design for all screens before development starts. Development in 2-week sprints: working software delivered to staging every two weeks. QA integrated throughout the build, not at the end. Launch: deployment, performance monitoring, and handover. Post-launch support available. You have visibility into progress throughout -- not a black box that opens at week 12.
You do. Full IP ownership transfers at project completion. We don't license software back to you or retain rights. You receive all source code, documentation, and access credentials. We're happy to be your ongoing development partner -- but you're never locked in.
