Design and engineering for SaaS founders
We build the whole subscription product. The marketing page is the easy part. The hard part is the payment system that has to clear the first charge, the auth that has to pass the first security review, and the product that has to show its value before someone thinks about cancelling.
The problems we hear most
Billing is five different tools and none of them talk to each other
The founder ends up spending the evenings holding together the payment processor, the subscription manager, the customer email tool, and the shared sheet for extending dead trials. By month-end no one really knows how many weeks of runway are gone.
A no-code MVP that put hard ceilings in the wrong places
The founder arrived with a prototype that got him the first three customers, and at four customers the no-code ceiling shows. The internal views are fake, the audit log doesn't exist, and the first prospect who asks how customer data is kept separate stalls the deal.
A pricing page that talks to engineers, not to buyers
The plans were copied from a competitor. The comparison table runs too long and nobody reads it through. What the customer consumes above the plan never makes it onto the invoice.
Moko, a customer support workspace built whole
We designed and developed Moko from scratch, from the inbox to the portal where the customer searches on their own. Every screen the team touches every day was built with the same care, under a single design system.
How we built Moko
Moko replaces the full workspace a customer support team lives in, from the inbox to the portal where the customer searches on their own. The brief was clear: every screen finished to the same level of care, no polished hero followed by half-built drawers. That's the shape of work that breaks most support tools after the first launch. The inbox grabs all the attention, the reports stay rough for months, and the customer portal is something someone adds the evening before launch.
The design system was the project
Every screen at the same level of finish means the design system carried the project, not the other way around. We started with the parts every view would share, from the buttons to the tables to the charts, and built the product areas on top of that base. No screen got special treatment, no area asked for a one-off variant.
The inbox is the most important page
The inbox is where a support agent lives during the day. The reply window changes colour when switching between the public reply and the internal team note, so the mode is unambiguous before pressing send. Status changes are instant and reversible, and the interface never blocks waiting on the network. Tags and priority are edited directly from the message row, without opening another window. Above long conversations a summary appears automatically, telling the agent how the customer feels, what plan they're on, and what could help as a next step.
The whole page can be used by keyboard alone. The shortcuts cover the steps an agent repeats a hundred times a day. Whoever learns them never reaches for the mouse again.
A customer profile that doesn't make things up
Every customer carries their own story. The profile summarises the key stats in a strip, shows all the customer's open and closed tickets, and lets the team add custom fields directly from the row, without opening a separate window. The same view appears inside the inbox. Whoever opens a conversation immediately sees what plan the customer is on, where they're writing from, and what their last tickets were about. Everything stays in the same screen.
A knowledge base for the team and the customer
The knowledge base is written by the support team and read by customers. On the internal side it's an editorial tool, with the categories, the drafts, the published articles. On the public side, at /help, it's a real reading surface, with the search in the foreground, the categories grouped, and a table of contents inside each article. Both sides read from the same data. The agent who updates an article to close a ticket knows the same article is what the customer will find searching on their own.
Both themes designed together from the start
The light theme and the dark theme weren't added one after the other. They were designed together from the start of the project, and we worked with both active during development. The product pulls its colours and font sizes from the design system, and no value is hand-written inside an individual screen. When the theme changes, the charts and the status labels change alongside the buttons, and no part stays behind. Changing the colour of a chart category across the whole product is a one-place edit.
Why this matters for someone shipping a subscription product
A complete SaaS product is a system where the support team, the finance side, the leadership, and the customer each find their own place to work. Moko holds all of that inside one design system, and the product still looks like the same product when the team doubles or the brand changes direction.
What we deliver for this vertical
Auth with data isolated per customer
Each customer sees only their own data, and the rule is enforced inside the database itself. It's the answer in writing the security team of your first enterprise deal will want to see before signing.
Recurring billing that holds up at the edges
Mid-month upgrades, downgrades, renewals, and retries after a failed charge are calculated to the cent. The notifications Stripe sends are processed exactly once, even if they arrive twice, and the internal accounting ledger stays in sync.
A read on who is actually getting the product
We track the actions that predict renewal, not generic clicks. You can tell early who will stick and who is about to drift, before the cancellation email arrives.
An internal cockpit for your team
Refunds, plan changes, customer-level data access when something goes wrong, all from a UI. Your team stops diving into the database by hand.
Compliance ready for the first audit
Different permissions for each role, a log of the operations that matter, GDPR export and delete. What your first enterprise customer asks to see is already there, ready.
Defence against trial reset abuse
We check the email domain, recognise the device signing up, and cap the retries from the same network. Opening a private window is no longer enough.
A stack that pays for itself twice
Every layer here pays for itself twice. Once when you ship the first version of the product. Once when you start scaling, hiring, or answering the hard questions from the procurement team of your first enterprise customer. We pick the stack that holds up in that second moment, not the one that only works today.
The public site, the in-app product, and the admin panel live in one Next.js repository. The pricing page is static and ranks well on search engines. The product itself, once the user is inside, is fast from the first click. Marketing and product work on the same codebase, with no argument about which framework owns the signup flow.
Customer data is isolated inside the database itself, and not in application code. The reason is simple. The first serious enterprise deal you chase goes through a security review, and that review asks the same question every time, namely how you guarantee that customer A cannot see customer B's data. With a managed Postgres the answer fits in a handful of lines of code, and you can put it in writing in the contract. The same database also holds user accounts, file uploads, and real-time updates, and your team stops stitching together three services that disagree on who the user is.
Billing runs on Stripe. Subscriptions, plan changes, and retries after a failed payment are handled by Stripe for us, so the billing layer grows with the product instead of asking for a rewrite when the first real customers sign. If Stripe has a hiccup, the internal accounting ledger stays in sync and no customer gets charged twice. The customer manages their own plan from the Stripe portal, and your support team stops doubling as the billing department.
Abuse protection runs on a managed Redis service, with no server for you to maintain. Customer files live in an object storage that doesn't charge per download, and a user pulling the same file a thousand times doesn't turn into a four-figure surprise on next month's bill.
Every line of code is written in TypeScript, from the database queries to the views on the screen. It's the least flashy benefit and the most load-bearing. When an engineer leaves the team, when a feature is renamed, errors surface immediately instead of showing up six months later in production. Whoever opens the codebase the next day can move around without a guided tour.
Questions founders ask
What if I already have an MVP in Bubble?
We migrate it. The Bubble logic gets rewritten in real code, the data moves to Postgres, and the new product ships as a proper application rather than a no-code prototype with a low ceiling.
Can you build only the billing layer?
Yes, with a clear perimeter. We build the Stripe billing module as a self-contained piece, with the integrations wired in and an internal view for your team. The scope and price depend on how complex your pricing model is.
How do you handle free-trial reset abuse?
We treat it as a security layer, not a marketing trick. We check the email domain, recognise the device signing up, and cap the number of retries from the same network. Opening a private window is no longer enough.
What is the smallest scope you will ship to get to paying customers?
Three things at the start. Customer auth, billing that works, and the one core workflow that justifies the subscription, done well. Internal views and integrations come after the first paying customers tell you which one to build next. The unnecessary stuff gets cut before it is built, not after.
Do you stay on after launch?
Two options. The first is a clean handover to your team, with all the documentation and the design system in their hands. The second is staying on as an ongoing product partner. We don't vanish after launch.
