SaaS Development From First MVP To Live Platform

We build and grow subscription software, covering sign-up, billing, roles and the product itself, from the first MVP to a live platform. For Coach Catalyst we added a Stripe Connect marketplace and moved the front end to Vue 3 while customers kept using it.

What A SaaS Product Needs

A SaaS product is two things at once: the feature customers pay for, and the accounts, billing and admin that keep a subscription business running.

Core capability

Accounts, roles and teams

Sign-up, invitations and permissions for admins, team members and end customers.

Subscription billing

Plans, trials and upgrades through Stripe. Klingit bills its customers on multi-tier subscriptions.

Real-time features

Messaging, video and live updates. Whistle It runs secure video meetings on top of the open-source BigBlueButton engine.

Scheduled and bulk jobs

Work that runs in the background at scale. One40Connect sends scheduled and recurring text campaigns for its customers.

Data-heavy products

Products that crawl, track or process data all day. Clicks.so tracks thousands of keyword rankings without its server costs climbing.

Project story · Coach Catalyst

Turning a coaching tool into a marketplace that pays coaches directly

Coach Catalyst is a platform where fitness coaches run their client programs: scheduling, messaging and progress tracking. The product worked, but it was slow, hard to use and built on code that made new features risky.

The problem

Pages loaded slowly and people struggled to finish tasks. Coaches had no built-in way to get paid by their clients. The chat module was written in CoffeeScript and struggled under load. The codebase had never been planned for a community feature, and the front end was still on Vue 2.

What we changed

  1. 01Redesigned the interface for clarity and cut load times by optimizing code, requests and media.
  2. 02Built a Stripe Connect marketplace with OAuth onboarding, so coaches get paid by their clients directly and payouts are handled securely.
  3. 03Rewrote the CoffeeScript chat in Vue.js with real-time updates that hold up under load.
  4. 04Added a community module in phases, isolating its components so the rest of the product kept working.
  5. 05Migrated the front end from Vue 2 to Vue 3 with the Composition API, which also reduced the bundle size.

Where it stands

The platform is faster and easier to use, and the marketplace opened a new revenue stream for coaches and for the business. That is typical of SaaS work: most of the value comes from improving a live product without interrupting the customers who pay for it.

From Idea To Scale

We ship the smallest version paying customers will use, then let usage decide what comes next.

Discover

Shape The First Version

We agree the one workflow customers will pay for, plus sign-up and billing, and leave the rest for later.

Develop

Build For Many Customers

Tenant separation, roles and billing go in from the first sprint, with weekly demos of the product.

Scale

Grow With Usage

Product analytics show which features people use, and the roadmap follows them.

What To Get Right Early In A SaaS Product

Some SaaS decisions are cheap to change later and some are not. These are the ones we settle at the start.

How tenants are separated

Whether customers share a database or each get their own affects security, cost and how hard enterprise deals become later.

Billing and payouts

Subscriptions, trials, usage pricing or marketplace payouts like the Stripe Connect setup on Coach Catalyst all shape the data model.

Roles and permissions

Admins, team members and end customers need different access. Retrofitting permissions into a live product is slow and risky.

An MVP that is a real product

Ship the smallest version paying customers will use, with sign-up and billing working, and leave the rest for later.

Upgrades without downtime

Frameworks age. Coach Catalyst moved from Vue 2 to Vue 3 while customers kept using it, which is far easier when the code is kept tidy.

Usage data from day one

Product analytics show which features people pay for, so the roadmap follows evidence instead of guesses.

SaaS Development FAQs

What founders and product leads ask before building a SaaS product.

Building software that customers subscribe to and use in a browser or an app. It also covers what a subscription business needs around it: accounts, billing, roles, onboarding and analytics.

Yes. An MVP should include the core workflow, sign-up and billing, so you learn whether people will pay. Everything else waits for evidence.

We decide early whether customers share tables scoped by tenant or get separate databases, based on your security needs and target customers. Then that rule is enforced in one place in the code.

Yes. On Coach Catalyst we rewrote the chat, migrated the front end to Vue 3 and added a Stripe Connect marketplace while the platform stayed live.

Yes. We can place full-time engineers in your team, or take on a defined part of the roadmap ourselves.

You do. Everything we build for you, including the source code and the intellectual property in it, belongs to you.
