SaaS product development, from first release to paying users.
One team to design, build, host and market your SaaS product: a lean first version, billing that works, onboarding that gets people to value, and the search and email work that brings the next sign-up.
This page describes how we approach SaaS products. Ask us for relevant work samples.
Building the product is only half of the work.
Early SaaS teams are usually short on the same two things: time and certainty.
A first version that keeps growing
Scope creeps and the launch slips.
Sign-ups that don’t activate
People join but few reach the point where the product proves its worth.
The unglamorous parts
Plans, trials, invoices, failed payments, roles, backups and monitoring can take months if not planned.
Marketing blind to the product
An agency that has never opened the product can’t say which channel brought customers who stayed.
How we approach it
- Design the product, onboarding and acquisition as one system.
- Plan billing, accounts and permissions from the start.
- Judge everything by one shared set of numbers.
What a SaaS development company should cover.
- 01
MVP and product builds
We start by cutting the first release down to the one job a customer will pay for, then build it on a stack your future hires will recognise: typically React or Next.js, Node.js and PostgreSQL. Typed, tested code, in a repository you own from day one.
- 02
Multi-tenant architecture
Separate workspaces for each customer account, with data isolation, roles and permissions, team invites, audit logs and an admin panel for your own staff. We decide early whether tenants share a database or get their own, because changing it later is expensive.
- 03
Billing with Stripe
Plans, trials, seats or usage-based pricing, coupons, tax handling and invoices through Stripe Billing, plus the customer portal for upgrades and cancellations. We handle webhooks and failed payments properly, so access always matches what the customer has paid for.
- 04
Onboarding and activation UX
We map the steps between sign-up and the first useful result, then cut what isn’t needed. Sample data instead of empty screens, short checklists, helpful empty states and emails triggered by what users have or haven’t done yet.
- 05
AI features that earn their place
Search over your customers’ own documents, summaries, drafting assistants, classification and chat, built on models from providers such as OpenAI or Anthropic. We check cost, accuracy and data handling first, and say so when a plain rule would do.
- 06
Cloud, DevOps and product-led growth
Hosting on AWS, Google Cloud or Vercel with CI/CD, staging, backups and monitoring. On the growth side: SEO and content for the problems your product solves, paid acquisition on Google, Meta or LinkedIn, and lifecycle email for trials, activation and renewals.
How we would take a SaaS product from idea to launch.
A focused MVP typically takes six to twelve weeks; adding features or growth work to an existing product usually runs month to month. You see working software every week.

Week 1
Discovery and scoping
We sign an NDA, then learn who the product is for, what they pay for today and what the first release must prove. You get a feature list split into “launch” and “later”, and a written proposal within 7 working days.
- 2
Weeks 1–3
UX and architecture
Clickable designs for sign-up, onboarding and the core screens, reviewed in Figma. In parallel we fix the data model, tenancy, billing plans and hosting.
- 3
Weeks 3–10
Build in weekly releases
Features ship to a staging link every week with a written update. Authentication, billing and analytics events go in early, so you can test the full path from sign-up to paid account before launch.
- 4
Launch week
Launch and instrumentation
Production release, monitoring and error alerts, product analytics and conversion tracking, and the first onboarding emails. Code, cloud accounts and documentation are handed over to you.
- 5
Monthly, if you want it
Iterate and grow
An agreed number of hours each month for features and fixes, alongside SEO, content, ads and lifecycle email, reviewed against sign-ups, activation and paid conversions.
Who this is for, and who it isn’t.
A good fit if
- Founders with a validated problem who need a first version built properly, not a throwaway prototype
- Product teams that need extra senior developers or a designer for a set period
- SaaS companies with a live product that want onboarding, billing or AI features improved
- Teams that want the product and its marketing run from the same plan and the same numbers
Probably not for you if
- Ideas that haven’t been tested with a single potential customer yet: a few conversations first will save you money
- Products that need regulated certifications such as HIPAA or SOC 2 from the first release, unless your own compliance team leads that work
- Anyone looking for a partner to take equity instead of payment
What SaaS product development costs.
Cost depends mainly on user roles, integrations and billing rules, not screen count. We work on a fixed price for a defined MVP, or hourly and monthly for ongoing development and growth work. There is no lock-in, and ad spend is paid by you directly to Google, Meta or LinkedIn, never marked up. If a deliverable doesn’t match the agreed scope, we fix it at our cost.
Starting from $49
Questions we’re asked.
It depends on the number of user roles, integrations and how complex billing is. A single-role product with Stripe subscriptions costs far less than a multi-tenant platform with usage-based pricing and third-party integrations. After a short call we send a written proposal with a fixed price within 7 working days.
A focused MVP typically takes six to twelve weeks from approved designs to launch. Larger products are usually built in phases, so you can start charging customers before every feature exists.
You do. The repository, cloud accounts, Stripe account, domain and analytics are set up in your name, and the agreement assigns the code and designs to you. We sign an NDA before the first call.
Typically React or Next.js on the front end, Node.js with PostgreSQL behind it, hosted on AWS, Google Cloud or Vercel. If your team already works in another stack, we would usually build in that instead so they can maintain it.
Each customer gets a separate workspace, and every query is scoped to that workspace so one tenant can never see another’s data. We choose between a shared database with tenant IDs or separate schemas early on, based on your customers’ size and data requirements.
Yes. We start by checking whether the feature solves a real problem for your users and what it would cost per request. Common examples are search over customer documents, summaries, drafting help and automatic tagging, built with guardrails and logging.
Yes, if you want it. We would typically start with tracking and onboarding emails, then add SEO and content around the problems your product solves, and paid campaigns once we know which users convert. Every account stays in your name.
