What We Cover

  • Product Discovery: user research, problem definition, feature prioritization, and roadmap design — so you build the right thing before spending time building it right. The most expensive product decisions are the ones made without this step: features built for assumptions that real users immediately contradict.
  • UX & Design: information architecture, user flows, wireframes, and high-fidelity UI designed to convert, activate, and retain — not just to look good in a demo. Design decisions made here determine how long it takes users to reach value, and whether they come back.
  • Architecture & Data Modeling: technology selection, scalable backend design, multi-tenancy model, data schema, and API contracts established and documented before development begins. The architectural decisions made in week two of a SaaS build are the ones you live with for years — or pay to undo at the worst possible time.
  • Development & Testing: frontend, backend, APIs, and third-party integrations built iteratively with automated testing at every layer — so the codebase doesn't become something your engineers are afraid to change as it grows.
  • CI/CD & Deployment: infrastructure-as-code, automated pipelines, environment promotion controls, and deployment automation built in from day one — not retrofitted six months later when manual deployments have already caused two production incidents and made the team scared of Fridays.
  • Growth & Iteration: monitoring, product analytics instrumentation, A/B testing readiness, and ongoing feature development as you scale and learn from real users — so the product improves based on what people actually do, not what they said they wanted in a survey.

Common Triggers

  • "I have a validated idea and need to build it properly": not a throwaway prototype — a real product foundation with the architecture, multi-tenancy model, design system, and technical decisions that won't force an expensive rewrite six months after launch. You've done the market validation. Now you need the build to match the ambition, not cut corners that compound into problems the moment you get traction.
  • "We built an MVP ourselves and now need to professionalise it": no tests, no CI/CD, engineers afraid to deploy on Fridays, a codebase that's impossible to onboard new hires into, and infrastructure held together by tribal knowledge. These are the codebases we inherit regularly. We know how to systematically fix them — adding tests, automation, and structural improvements — without stopping delivery or rewriting everything from scratch.
  • "We're growing but our architecture isn't keeping up": slow deployments, frequent outages, database queries that time out under real load, and a team spending more time on incidents and bug fixes than shipping features. The architecture that got you to your first hundred customers is rarely the one that gets you to ten thousand. Scale requires a different foundation, and waiting until the system is actively failing to address it is the most expensive time to do it.
  • "We need to add capabilities our team can't build": AI features, complex usage-based billing, SSO and enterprise-grade auth, payment systems, or deep third-party integrations — specific technical domains where shallow implementation causes serious problems later. Your team is strong, but these are specialised areas where experience with the failure modes is the difference between something that works and something that becomes a liability.

Stages We Support

01

Zero → MVP

Validate your idea quickly with a working product users can actually use — not slides or prototypes.

02

MVP → PMF

Iterate fast on real user feedback. Improve retention, activation, and conversion based on data — not assumptions.

03

PMF → Scale

Harden the architecture, improve performance, and build the team processes and tooling for sustained growth.

04

Scale → Leadership

Competitive differentiation through product depth, ecosystem integrations, and platform extension for power users.

SaaS Foundations We Get Right

  • Multi-tenancy: proper data isolation, tenant configuration, and permission boundaries designed from the start — not bolted on after your first enterprise customer asks for it. Adding multi-tenancy to an existing single-tenant data model is one of the most expensive rewrites a SaaS team can face — it touches schemas, APIs, access controls, and billing simultaneously, and it tends to happen exactly when you've just closed your first significant enterprise deal and can least afford to pause delivery.
  • Authentication & authorization: SSO (SAML/OIDC), role-based access controls, API key management, MFA, and audit logs — the table stakes enterprise buyers expect before signing. A failed security questionnaire or a missing SSO integration is a deal-stopper in enterprise sales, and retrofitting SAML support into an existing auth layer under commercial deadline pressure is a different project than building it in correctly the first time.
  • Billing & subscription management: Stripe integration, plan and feature gating, usage-based billing, trial flows, upgrade/downgrade logic, and invoice management — the infrastructure that makes a SaaS business actually work. Billing built as an afterthought produces revenue leakage, failed webhook handling, and edge cases in trial and upgrade flows that quietly cost you customers and ARR without appearing in any report that makes the problem obvious.
  • Onboarding & activation: in-app onboarding flows, empty state design, activation metric tracking, and time-to-value optimisation — because acquisition without activation is just churn waiting to happen. A product with a strong value proposition and a poor onboarding experience loses users before they reach the moment that would have made them stay — and most teams don't realize how much this is costing them until they instrument the funnel and see where users drop.
  • Observability: error tracking, performance monitoring, user session analytics, and alerting so you know what's failing in production before your customers do. Without instrumentation from launch, you spend the first months of production learning about problems from support tickets rather than dashboards — and the data that would have told you which features are actually used, what's causing churn, and where sessions break doesn't exist yet because it was never wired up.
  • Security baseline: secrets management, dependency scanning, pen test readiness, and data handling practices that let you answer enterprise security questionnaires with confidence. The typical first-time security questionnaire from an enterprise prospect exposes credentials in environment variables, vulnerable packages, missing audit logs, and data handling practices that were never formally documented — findings that delay or lose deals that your product otherwise deserved to win.

Technologies We Build With

  • Frontend: React, Next.js, Vue, TypeScript, Tailwind CSS — fast, accessible interfaces with component libraries designed to grow with the product without becoming a maintenance burden.
  • Backend: Node.js, Python, Go, .NET — API-first architectures, background job systems, webhooks, and the server-side logic that powers SaaS products reliably at scale.
  • Auth & identity: Auth0, Clerk, NextAuth, or custom OAuth — SSO (SAML/OIDC), social login, MFA, API keys, and the role/permission model your enterprise customers require.
  • Billing: Stripe, Paddle, Chargebee — subscription plans, usage-based billing, trial logic, proration, coupon management, and the revenue reporting your finance team needs.
  • Data & infrastructure: PostgreSQL, MongoDB, Redis, S3, Terraform, Kubernetes, AWS and Vercel — the right data stores and deployment targets for your performance and cost requirements.
  • Analytics & observability: PostHog, Segment, Sentry, Datadog — product analytics, error tracking, and performance monitoring wired up from launch so you have data from day one.

Who We Work With

  • Founders building their first SaaS: a validated idea and a clear problem to solve — you need a technical delivery partner who can act as a co-founder on the product side without the equity cost. In practice, that means being in the product decisions, not just the implementation ones — asking whether the right thing is being built, how users are expected to reach value, and which technical decisions will constrain you six months from now if made without that consideration today.
  • Bootstrapped and VC-backed startups: seed to Series A, under pressure to ship fast and demonstrate traction — without accumulating technical debt that kills your velocity before you reach scale. The companies that struggle at Series A often have a strong product story and a codebase that can't keep up with it — slow deploys, brittle tests, a monolith that can't be split, and an engineering team spending half their time on maintenance that should have been preventable.
  • Established companies launching a SaaS arm: internal tooling or domain expertise being turned into a standalone product — needs a team who can move quickly and owns the full build. The challenge is usually not the domain knowledge, which the company already has, but the ability to execute at product-company speed while navigating internal stakeholder requirements, compliance expectations, and the inertia of an organisation built around a different delivery model.
  • SaaS teams that have stalled: existing product, growing team, but engineering velocity has slowed, incidents are increasing, and every sprint feels harder than the last. The pattern is consistent — a codebase that was built for speed and never refactored, test coverage too thin to refactor safely, deploys that have to be manually supervised, and a team that's spending more time managing the consequences of past decisions than moving the product forward.

Why Kubrik for SaaS

  • One team from whiteboard to production: product discovery, UX, frontend, backend, infrastructure, and DevOps — handled by a single delivery team with shared context, not passed between agencies. The handoff gaps between design and development, and between development and deployment, are where most SaaS projects lose time and quality. We close those gaps by design.
  • We know which shortcuts cost you later: we've built SaaS products at every stage, so we've seen what happens when multi-tenancy is added as an afterthought, when billing is patched in at month six, and when a codebase built for speed can't survive a single engineer leaving. We make those decisions correctly upfront — not because we're cautious, but because we've watched the alternative play out.
  • Engagement that adapts to your stage: a sprint team for early validation, a dedicated squad for scaling, targeted augmentation for specific capability gaps — we don't lock you into a fixed engagement model that doesn't fit where you are. As your product evolves and your team grows, how we work with you can change without renegotiating from scratch.
  • We care about your product metrics, not just our delivery metrics: story points closed and velocity charts are easy to optimise for. We ask harder questions — are users activating? What's driving churn? Which features are actually used? — and build accordingly. Our job isn't to ship code; it's to help your product succeed.

Results You Can Expect

A production-grade SaaS product built on foundations that hold up as you grow — not ones that force a rewrite the moment you hit real scale. Faster time to market on new features, fewer production incidents, and a codebase your next hire can contribute to on day one. The technical decisions made early compound over time: the right multi-tenancy model, the right data architecture, the right observability setup — built in from the start instead of retrofitted under pressure. Founders we've worked with consistently describe the same outcome: they stopped worrying about the engineering and started focusing on the business.
