RaftLabs is an AI-first tech studio that builds SaaS products for startups and growth-stage companies. Since 2015, we've shipped 100+ products including B2B SaaS platforms, marketplace apps, and AI-native tools for clients including Aldi, Nike, and Vodafone. We deliver SaaS products in 10-16 weeks at a fixed cost with full source code ownership and no vendor lock-in. RaftLabs is a tech studio, not an agency. One team owns your product from architecture through launch, no handoffs, no relay race between four vendors.
According to Gartner, worldwide SaaS revenue grew 16.7% to $218.5 billion in 2024, making it the fastest-growing segment of enterprise software spending. That growth means more SaaS buyers with higher expectations for data isolation, compliance posture, and billing flexibility — all architecture decisions that have to be right from the first sprint.
The architecture decisions you make when building your MVP constrain you at every subsequent stage. Shared-schema multi-tenancy that works at 50 customers breaks at 5,000. Subscription billing bolted on after launch is harder to change than if it was designed in. Role-based access retrofitted after enterprise deals require it is a rebuild.
SaaS development done right means making the right architectural decisions at the start, not paying for them at Series B.
Key Insight
Two SaaS platforms we've built since 2015 were acquired after launch: Gula (acquired by Runchise) and a food logistics SaaS (acquired by Gojek). In both cases, the multi-tenant architecture we shipped held up under the acquiring company's scale without a rebuild.
Gula is one example. We built the multi-platform food order management SaaS, including multi-tenant data isolation and Stripe billing, in 16 weeks. It was acquired by Runchise shortly after launch. Read the full case study.

Capabilities
What we build
01Multi-tenant SaaS platforms
SaaS products where one codebase serves many customers with complete data isolation. The tenancy model matches your buyer, and cross-tenant isolation is enforced by an automated security test suite, not a one-time design decision.
- Built with
- PostgreSQL · Temporal.io · Step Functions
02Subscription and billing infrastructure
Recurring subscriptions, trials, proration, usage-based metering, and invoicing, with webhook events processed idempotently. A dunning sequence runs from the first payment-failure email through account suspension at day 14, and any feature can be plan-gated without a code deployment.
- Built with
- Stripe Billing · LaunchDarkly · Unleash · Lago
Team and workspace management, audit logs, API key management, and webhook delivery for product events. The access controls enterprise buyers check before procurement approval, built in from the start, not added when the first enterprise deal requires them.
- Built with
- SSO · SAML · OAuth · RBAC
04SaaS API and integration layer
Public API for third-party integrations, webhook delivery for product events, and native integrations with the tools your customers already use. The integration surface that makes your product a platform, not a silo.
- Built with
- Zapier · Make · Slack · Salesforce · HubSpot
05Admin and operations tooling
Internal admin dashboard for managing tenants, monitoring usage, and handling billing overrides without database access. Usage analytics and churn signals surface to your customer success team, so they can run the product without relying on engineers for every support task.
06SaaS infrastructure and DevOps
Production infrastructure with staging environments, database backups, monitoring and alerting, and auto-scaling. It supports zero-downtime deployments and handles traffic spikes, deployed to your cloud account and managed by you after handoff.
- Built with
- AWS · Vercel · GCP · CI/CD
100+ products shipped since 2015. We know what breaks SaaS products at scale.
Fixed cost. 10-16 week delivery. Full source code ownership. No dependency on us to run your product.
Process
How we build SaaS products
Before writing code, we design the data model, tenancy model, and API structure. The architecture review catches decisions that are cheap to change now and expensive later, then documents them for your sign-off before development starts.
02Fixed cost on defined scope
We scope the product before pricing it: a discovery session, a wireframe to validate scope, and a defined feature list set the fixed cost. If scope exceeds your budget, we cut to the essential core and build the rest in a later phase, with no hourly billing.
03Working software at every milestone
We build in two-week sprints with a deployed build at the end of each, so you see working software every two weeks, not a finished product after 16. Problems surface at sprint review when they cost hours, not at launch when they cost weeks.
04Built for your engineering team to take over
We write code as if we're handing it to a different engineering team, because we usually are: standard frameworks, documented APIs, a clean codebase, and infrastructure-as-code. Your future engineers can extend it without reverse-engineering our decisions.
SaaS architecture decisions made right the first time
Multi-tenancy, subscription billing, and enterprise features designed in from day one. Fixed cost.
How we work
From scope to shipped
Every project follows the same four phases. Scope is locked and price is fixed before development starts.
- Week 1
01Discovery and scope
We map the problem, the user, and the workflow. You leave week 1 with a written scope document, a defined feature list, and a fixed-price quote. No development starts without your sign-off.
- Weeks 2-3
02Architecture and design
We design the data model, tenancy model, and API structure before writing code. Wireframes validate the UX. Architecture decisions made here cost a fraction of changes made in week 8.
- Weeks 4-12
03Build, integrate, and QA
Working software deployed to staging at the end of sprint one. Bi-weekly demos with milestone sign-off before the next payment. QA runs in parallel with every sprint, not as a phase at the end.
- Weeks 12+
04Launch and handoff
Production deployment with monitoring activated on launch day. 8 weeks of post-launch support included. Full source code, infrastructure definitions, and documentation transferred to you at project end.
Why us
Why SaaS founders choose RaftLabs
01Senior engineers build what they scope
The engineers who assess your product also build it. No bait-and-switch, no offshore handoff after the contract is signed. The team you meet in week 1 ships in week 12.
02Fixed price before development starts
We scope the product, calculate the cost, and lock it in writing before any development starts. A scope change is a change request: priced, agreed, or dropped. It never absorbs into the project and appears on the final invoice.
039 years and 100+ products shipped
Clients include Vodafone, T-Mobile, Aldi, Nike, Cisco, and Lockheed Martin. Track record across B2B SaaS, marketplace, AI-native platforms, and fintech. We have shipped multi-tenant products for US, UK, and Australian buyers.
04Compliance built in from the start
GDPR, HIPAA, SOC 2 - compliance requirements are scoped in week 1, not retrofitted before launch. We have shipped HIPAA-compliant systems for US healthcare clients and GDPR-compliant products for European markets.
