How long does it take to build an MVP in London?

Most MVP builds for London startups take eight to sixteen weeks from product discovery to first production release. A focused MVP with one user journey, Stripe integration and REST API backend takes eight to ten weeks. A SaaS product with multi-tenant data isolation, subscription billing and AWS deployment takes twelve to sixteen weeks. Softomate uses Agile Scrum with two-week sprints, so working software is available for user testing throughout delivery. Discovery and architecture take two to three weeks. UAT and production submission add one to two weeks. A scoped discovery workshop gives a precise timeline once the feature set, integrations and compliance rules are confirmed.

Can you help define the product before starting development?

Yes. Softomate runs product discovery workshops that define user personas, core jobs-to-be-done, feature scope and technical architecture before build starts. Discovery produces a prioritised backlog, user journey maps, wireframes and a fixed-price delivery plan. Founders and product managers get clarity on what will and will not be in the MVP. This helps prevent scope creep and helps the first release test the riskiest product assumptions rather than building every idea. Most clients complete discovery in one to two weeks. Discovery output directly informs sprint planning for the build phase.

Does Softomate build UK GDPR-compliant SaaS products?

Yes. UK GDPR compliance is specified in product architecture before build starts. Data minimisation, consent capture, subject access request workflows and retention schedules are built into delivery. AES-256 encryption protects data at rest and in transit. OAuth 2.0 scoped permissions help prevent unauthorised access to multi-tenant data. ICO breach notification hooks and deletion workflows are mapped during discovery for regulated products. Softomate clients in financial services also receive FCA Consumer Duty and HMRC AML controls in the same delivery scope. A compliance review happens before launch and after thirty days of live traffic.

Can Softomate integrate Stripe into our SaaS product?

Yes. Softomate integrates Stripe subscriptions, trial periods, usage-based billing and invoice management into SaaS products through the Stripe API and webhook event system. Plan upgrades, cancellations and failed payment retries are handled automatically. Stripe Customer Portal gives subscribers self-service access to billing history and card management. UK GDPR-compliant consent records and payment data handling are designed into the integration from the start. Most Stripe integrations are completed within two to three sprint cycles. Softomate has also integrated Stripe with React frontends, Python backends and multi-tenant PostgreSQL databases.

What happens after the MVP launches?

After MVP launch, Softomate provides a prioritised product backlog, handover documentation and an optional ongoing support and development retainer. The backlog captures features deferred from the MVP scope, performance improvements and integrations identified during UAT. CI/CD pipelines keep deployments automated so new releases go out without manual intervention. Monitoring dashboards on AWS track uptime, error rates and response times. Most clients move into a monthly sprint retainer for iterative feature releases within four to eight weeks of launch. Explore our bespoke software development services and web application development services for the next growth phase.

Benefits and fit

What should a product development partner help you launch?

Move from a validated idea to production software that can charge customers, stand up to due diligence and keep growing.

Faster time to first launch, with visible progress

Product discovery workshops and prioritised MVP scoping get London startups from validated concept to working production software in eight to sixteen weeks, not six to twelve months. Two-week Scrum sprints with demo sessions give founders and product leads working software to test and share with investors at every delivery milestone, not just at the end.

Revenue-ready Stripe integration

Stripe subscription billing, trial management and webhook automation are built into the product from the first sprint, so the platform charges customers from day one of launch.

UK GDPR compliance from architecture

Data minimisation, consent capture and AES-256 encryption are specified in product architecture before build, helping prevent costly compliance rework at the point of investor or enterprise sales due diligence.

A scalable, maintainable architecture

PostgreSQL multi-tenant data isolation, AWS auto-scaling and Docker containerisation are designed to handle growth from ten to ten thousand users without a platform rewrite between funding rounds. Git repositories, CI/CD pipelines, runbooks and handover documentation mean your in-house team or a future engineering hire can extend the product without rebuilding from scratch.

What we deliver

What does product development with Softomate include?

Five services cover the route from discovery to a live, billing product and its later releases. Expand a service to see what you receive; your written proposal confirms the scope.

MVP development and product discovery

Founders and product managers get a structured discovery process that defines user personas, core jobs-to-be-done and a prioritised MVP feature set before build starts.

Discovery produces wireframes, a technical architecture plan and a fixed-price delivery roadmap.

React frontends and Python backends are then built in two-week Agile sprints with founder review sessions at each boundary.

SaaS platform architecture and build

Growth-stage teams get multi-tenant SaaS platforms with PostgreSQL data isolation, OAuth 2.0 authentication and Stripe subscription billing built on AWS.

Docker containers and CI/CD pipelines automate testing and deployment on every sprint cycle.

GraphQL and REST API layers support mobile clients and third-party integrations without rebuilding the backend for each new channel.

Stripe billing and subscription management

Monetisation-ready products get Stripe subscriptions, trial periods, usage-based billing, invoice management and the Stripe Customer Portal integrated in one delivery scope.

Webhook events for plan upgrades, cancellations and payment failures are handled automatically.

UK GDPR-compliant consent records and payment data handling are specified in architecture before the first sprint starts.

REST API and third-party integration

Product teams get REST API layers and webhook integrations connecting their platform to Salesforce, HubSpot, identity verification services and payment gateways.

OAuth 2.0 authentication and rate-limiting are built to production standards.

Integration testing and UAT cover field mappings, error handling and data-consistency rules before any customer-facing release goes live.

Post-launch iteration and retainer development

Post-launch teams get a prioritised feature backlog, CI/CD-automated deployments and a monthly sprint retainer for iterative product releases.

Monitoring dashboards on AWS track uptime, error rates and response times.

Softomate embeds alongside growing in-house engineering teams using your existing GitHub, Jira and AWS tooling without disruption to live product operations.

Technical choices

Which technical choices shape your product?

Three groups of technical decisions determine whether the product can grow, bill customers and release safely.

Interface and data

React and Next.js product frontends use component libraries, TypeScript type safety and server-side rendering to give SaaS products fast, accessible interfaces for desktop and mobile users. PostgreSQL multi-tenant data architecture uses row-level security, schema separation and indexed queries to isolate tenant data and keep platforms performant as customer counts grow.

Billing and access

Stripe API and webhook automation handle subscription lifecycle events, trial management, invoice generation and payment retry logic from day one. OAuth 2.0 and JWT authentication use scoped tokens, role-based access control and HTTPS enforcement to protect user accounts and multi-tenant product data for UK GDPR compliance.

Hosting and delivery

AWS cloud and Docker deployment run containerised applications on AWS ECS or Elastic Beanstalk with RDS managed databases and S3 storage that scale automatically under user load. CI/CD pipeline automation with GitHub Actions and AWS CodePipeline handles testing, linting and deployment, so every sprint produces a reviewed, production-ready release.

Why Softomate and aftercare

Why choose Softomate for software product development?

A fixed price after discovery, production-grade foundations and support after launch.

Software development work shown on the Softomate homepage

Discovery first, then a fixed price

Softomate runs product discovery workshops that define user needs, feature scope and architecture before any build starts, helping prevent costly scope changes mid-sprint.

Softomate quotes fixed project prices after discovery, so founders know total cost and delivery milestones before committing to a build contract.

Focused software starts from £15,000 and a SaaS MVP from £25,000, with scope agreed before development. MVP fixed price is set after a Discovery Week that produces a written scope, architecture decision record and feature priority matrix.

The V2 and V3 roadmap is included in the Discovery output, so you have a full product plan, not just an MVP.

Production-grade and revenue-ready from sprint one

Stripe billing, trial management and UK GDPR consent flows are built into the product from sprint one, so commercial features are not bolted on at the end of delivery.

We do not build prototypes with technical debt baked in. Our standard stack (React/Next.js frontend, Node.js API, PostgreSQL, AWS ECS with autoscaling) is production-grade from the first deployment. It is designed to grow without a platform rewrite.

B2B SaaS products require multi-tenancy (data isolation per customer), subscription billing (Stripe integration with trial, paid and enterprise tiers) and usage metering (API calls, seats, storage). All three are included in the standard MVP scope, not sold as add-ons.

PostgreSQL multi-tenant isolation, Docker containers and AWS auto-scaling are designed to let the product handle growth without a full rewrite between seed and Series A.

Compliance by design and support after launch

Data minimisation, AES-256 encryption and consent workflows are specified in architecture before build, helping prevent compliance rework at investor or enterprise sales due diligence.

SaaS products that process personal data require a Data Protection Impact Assessment, Data Processing Agreements with all sub-processors and privacy-by-default architecture. We produce all documentation and configure your data handling to ICO guidance before launch.

CI/CD pipelines, monitoring dashboards and a monthly sprint retainer keep product releases flowing after launch without rebuilding team capacity from scratch.
