SFDIFYSaaS development from a studio that runs its own SaaS.
SFDIFY is a SaaS development company. We design and build multi-tenant products with billing, roles, analytics and the operational tooling behind them, and we run SaaS products of our own, including Yolda, Segeo and MuChat.
SaaS product development services.
Multi-tenant architecture
Accounts, workspaces and data separation designed in from the start, not bolted on after the first big customer.
Subscriptions and billing
Plans, trials, upgrades and invoices, with Stripe billing wired into the product.
Roles and permissions
Team invites, roles and admin controls, so every customer can manage their own people.
Admin and operations tooling
The internal side: support views, account management, audit trails and the dashboards your team needs.
Analytics and product metrics
Activation, usage and revenue tracked from day one, so decisions come from data.
AI features
Assistants, automation and smart defaults built into the product where they genuinely help users.
Segeo: a SaaS that publishes every day.
Small businesses know they should publish useful content to be found on Google and in AI answers, but rarely have the time to write it.
- A multi-tenant SaaS with an account per business
- Topic planning that avoids repeating itself
- A useful post written and published to each customer's site every day
- Instagram posting from the same account
- Subscription plans from $89 a month
Segeo publishes for its customers every day. It also writes this site's blog, so we see the product the way a customer does.

A good fit when
- ✓You are launching a subscription product, or turning an internal tool into one.
- ✓You need accounts, roles, billing and admin done properly from the start.
- ✓Your current SaaS has outgrown its first codebase.
- ✓You want a team that has handled billing, support and on-call for its own SaaS.
Probably not a fit when
- ×You only need a marketing website. See our web work instead.
- ×The idea is not tested yet. Start with an MVP.
- ×A no-code tool already handles your users and billing well enough.
From first call to launch.

What drives the cost of SaaS development.
A SaaS is a product plus the business machinery around it. These factors decide the effort.
Core product scope
The main job the product does, and how many workflows it needs on day one.
Multi-tenancy and roles
Workspaces, team invites, roles and data separation for every customer.
Billing
Plans, trials, upgrades, invoices and tax handled through a provider such as Stripe.
Integrations and AI
Each third-party API or AI feature adds work and testing.
Admin and analytics
The internal tools, support views and metrics your team needs to run it.

What does a SaaS development company do?
It designs, builds and often helps operate software sold as a subscription: the product itself, plus the accounts, billing, permissions, analytics and admin tools behind it.
Why hire a studio that runs its own SaaS?
Because running Yolda, Segeo and MuChat means we handle billing edge cases, support, on-call and churn ourselves. That experience shapes how we build client products.
What tech stack do you use?
Usually TypeScript with React and Next.js, Node or Python, Postgres, and AWS or Azure, plus OpenAI, Anthropic or Gemini for AI features.
Can you work on a SaaS product that already exists?
Yes. We can review the current codebase and product, then continue from there instead of starting over.
How long does it take to build a SaaS product?
It depends on the core workflows, billing and integrations involved. We usually recommend a lean first release that real customers can pay for, then growth from there. Projects typically start 2 to 4 weeks after the first call.
Can you add billing and subscriptions to our existing product?
Yes. Plans, trials, upgrades and invoices can be added to an existing product, with Stripe billing wired into your accounts and permissions.
