Based in Ahmedabad, India, working with SaaS, product and enterprise teams in the UK, Europe, Middle East and beyond.
Designed for long term product scaling, not one off projects.
QalbIT partners with SaaS founders, product leaders and CTOs who already have users in production, but feel that engineering capacity, stability or delivery practices are holding growth back. Our Product Scaling Team plugs into your environment and helps you scale product development without losing control.
You have paying customers, growing demand and a clear roadmap, but feature delivery is slow, quality issues keep coming back and you are constantly pulled into technical firefighting.
How we help
We provide a small, stable product scaling squad that owns day to day engineering, reduces incidents and ships roadmap items while you focus on customers, sales and strategy.
You look after product strategy and stakeholder expectations, but the backlog keeps growing and the current team cannot deliver at the speed or quality you need.
How we help
We turn your roadmap into a realistic delivery plan, improve collaboration between product and engineering and ensure that each sprint results in usable, measurable increments.
You own the architecture and internal team, but need additional capacity and disciplined engineering practices from a product development team in India that respects your standards.
How we help
We work inside your repositories and tools, follow your review process and take responsibility for specific modules or streams, from refactoring and performance to new features.
You rely on an internal platform or custom software that is critical to operations, but performance problems, bugs and missing features are limiting growth.
How we help
We stabilise the system, put monitoring and release discipline in place and then work through the roadmap so your teams can rely on the product every day.
What we take ownership of
Our Product Scaling Team focuses on the parts of engineering that matter most once you already have a live product: stability, performance, predictable delivery and continuous improvement. We work as an integrated product development team rather than a ticket only vendor.
Plan and deliver feature releases in small, reviewable increments with clear acceptance criteria, demos and impact tracking.

Many clients start with a stabilisation and scaling phase, then continue with us as an ongoing product development team.
We deliver product scaling work from Ahmedabad, India, partnering with SaaS and software companies across India, the UK, Europe and the Middle East who need a mature engineering team without building a large in house department immediately.
How we work together
Our process for product scaling starts with understanding your current reality: codebase, team, users and business goals. From there we stabilise the foundation, set up a predictable delivery rhythm and keep improving performance and reliability while shipping new value.
Most Product Scaling Team engagements run for 6–18 months, with visible improvements in stability and delivery speed usually appearing in the first 6–12 weeks.
Codebase and product health review
We review your repositories, environments, deployment process, monitoring and backlog. The goal is to understand what is working, what is fragile and what is blocking faster delivery.
Key outputs: Health report with key risks, quick wins and a prioritised list of technical and product improvements.
Roadmap and priorities alignment
We work with founders, product and technology leaders to align on objectives, must ship initiatives and constraints, then create a roadmap that balances new features with stabilisation work.
Key outputs: Shared roadmap, high level milestones and an initial 6–12 week delivery plan.
Stabilise and harden
We tackle critical bugs, improve test coverage, implement monitoring and harden the deployment process so releases become safer and easier to repeat.
Key outputs: Reduced incident volume, clearer observability and a safer path for frequent releases.
Feature delivery sprints
Once the foundation is stable, our Product Scaling Team runs regular sprints, shipping features, refactors and improvements with demos, release notes and impact tracking.
Key outputs: Regular feature releases, updated documentation and visibility into what shipped and why.
Performance and scalability
We profile the system, optimise queries and caching, adjust infrastructure and address architectural bottlenecks so the product can handle growth without constant fire drills.
Key outputs: Performance benchmarks, optimisation changes and recommendations for future capacity planning.
Continuous improvement and handover
We embed good practices into your workflows, document critical parts of the system and ensure your internal team can operate and extend the product confidently.
Key outputs: Living documentation, handover materials and a roadmap for the next 6–12 months of product scaling.
Different products and teams need different levels of support. We structure our Product Scaling Team engagements so you can start with a focused stabilisation phase and then grow into a long term partnership if it makes sense.
A focused engagement to review the codebase, fix critical issues, introduce basic monitoring and address high risk areas that block faster delivery.
Deliverables: Health report, stabilisation changes, monitoring setup and recommendations for the next phase.
A stable squad of backend, frontend, QA and DevOps engineers working as your long term product development team.
Deliverables: Ongoing feature delivery, refactoring, performance work and shared ownership of product health.
A compact pod that owns specific modules, integrations or strategic initiatives while your core team focuses on other priorities.
Deliverables: Module or feature ownership from design to deployment, with documentation and handover.
Experienced engineers embedded directly into your team, following your ceremonies, tools and code standards while still backed by QalbIT processes.
Deliverables: Additional capacity aligned to your sprint plan with shared KPIs and continuous knowledge transfer.
Before any engagement starts we share a clear proposal that covers scope, assumptions, timelines, team composition and commercial terms so you understand exactly how your product scaling budget will be used.
We are often brought in after an initial launch or a challenging first build. These examples show how our Product Scaling Team helped stabilise, extend and professionalise existing products.
Multi tenant link management SaaS covering short links, QR codes and campaign analytics. QalbIT helped move from early MVP to a more robust, scalable platform.
Operations platform for internet service providers handling onboarding, billing, tickets and network data. QalbIT refined modules and improved reliability as customer count grew.
Platform for limousine bookings with operations dashboards and driver apps. QalbIT continued development after initial launch to improve stability and add features.
Alongside these products, our Product Scaling Team has supported fintech, HR, field operations, education and logistics platforms. Many engagements are under NDA, but they follow the same pattern: stabilise, scale and deliver features with clean engineering practices.
Scaling an existing product is not only about adding more code. It requires the right stack, observability and disciplined delivery practices. We combine modern tools with pragmatic engineering so your team can move faster without losing control.
Strong, maintainable backends that can evolve as your product grows.
Responsive, accessible interfaces aligned with your brand and design system.
Mobile apps where they are part of the product experience or operations.

Contact our expertsA Product Scaling Team is the right fit when you already have a working product or MVP in the market and you need to ship features faster, improve performance and stability, or prepare for the next stage of growth. Typical triggers include frequent production incidents, a growing backlog your internal team cannot keep up with, or pressure from customers and sales for new capabilities.
An MVP team focuses on getting the first version of your product live with a lean feature set. A Product Scaling Team works on an active, real-world product. The focus shifts to reliability, performance, debt reduction, new feature delivery and long-term architecture. We need to respect existing users, data and releases, while still shipping meaningful improvements every sprint.
Yes. Most scaling engagements are collaborative. We often plug in as a dedicated squad that works with your CTO, product managers and existing engineers. We clarify responsibilities upfront — for example, QalbIT owning specific modules or streams — and align to your coding standards, review process, infrastructure and ceremonies.
We usually begin with a structured technical audit: codebase review, architecture and infra assessment, monitoring and incident history. Based on that, we classify debt into high-risk issues that must be addressed quickly and lower-risk refactors that can be scheduled over time. Our goal is to stabilise the product while creating room for new features, not to rewrite everything from scratch unless absolutely necessary.
Many scaling engagements run for 3–9 months or more. We start with a short discovery and audit, then define a prioritised roadmap covering stability work, performance improvements, UX fixes and new features. A dedicated QalbIT squad then executes in sprints with regular demos and releases. Over time we can either continue as your long-term squad or help you transition to a larger internal team.
We put strong emphasis on environments, testing and release practices. That means working with staging environments, automated and manual regression tests for critical flows, feature flags where appropriate and controlled rollouts. We avoid large, risky releases and instead ship smaller, well-tested increments with clear rollback strategies.
Success is usually measured in concrete outcomes: reduced incidents and support tickets, faster response times and page loads, more predictable release cadence, improved conversion or retention, and a clearer roadmap with debt under control. We work with you to define 3–5 key KPIs at the start and then report against them throughout the engagement.
We aim to keep your time focused on decisions, not micromanagement. Typically we agree on a cadence of weekly or bi-weekly planning and review calls, with async updates in between. Product owners help prioritise the roadmap and sign off on releases. For strategic decisions around architecture or major refactors, we bring clear options and trade-offs for your leadership to consider.
Yes. In addition to engineering, we support product and technical planning: defining themes and epics, sizing work, sequencing releases and highlighting risks. For clients building internal teams we can help structure roles, handover plans and onboarding so that new hires can take over smoothly from the QalbIT squad over time.
Most product scaling engagements begin with a short call where we understand your current product, pain points, incident history and growth goals. We then propose an initial audit and a 6–12 week plan that balances stabilisation, improvements and new feature work. To begin, you can contact us with details of your live product or schedule a scaling discovery call.
