What we build

These are the most common categories. If yours isn't here, it probably still fits.

Custom CRM

Built around your actual sales pipeline. Not generic, not a glorified spreadsheet.

Quotes and calculators

Complex pricing logic wrapped in a simple interface your customers actually use.

Client portal with roles

Separate access for companies, employees, admins. Each sees what's relevant.

Appointment system

Bookings, confirmations, reminders — synced with your calendar and WhatsApp.

Dashboard / internal panel

Your metrics in one place, with the logic only your business understands.

Inventory / ops apps

Stock, orders, internal flows — without expensive monthly SaaS licences.

Challenge

Build a single product that serves three very different audiences — corporate HR contracting wellness programs, certified coaches offering their services, and employees enrolling in sessions — across two countries (Canada and Mexico) with distinct cities, currencies, and languages.

What we built

A complete B2B platform: marketing landing with interactive cost calculator, a Company dashboard for contracts and enrollments, a public coach directory filterable by discipline and city, and a Coach dashboard with multi-step profile (info, disciplines, media, availability, pricing) including a weekly availability grid. Auth with role-based routing and dark/light mode throughout.

Why it's a system, not just a landing

  • Three distinct dashboards: Company/HR, Coach, Employee — each with its own sidebar, metrics and flows
  • Public coach directory filterable by discipline (HIIT, Strength, Yoga, Cardio, Meditation) and city (Guadalajara, Vancouver)
  • Interactive cost calculator on the landing tied to team size and frequency
  • Multi-step coach onboarding with progress percentage (Basic Info → Disciplines → Media → Availability → Pricing)
  • Weekly availability grid where each coach toggles slots that companies then see live
  • Company panel tracks active contracts, employees, pending approvals and billing
  • Multi-country ops: en-CA + es-MX, CAD + MXN, two cities live
  • Custom design system: dark/light mode, neon #c8fa5f accent, condensed uppercase typography

Frequently asked questions

What people ask us before commissioning a custom system.

How is this different from a landing page?+

A landing page captures interest — one audience, one action. A custom system runs an actual business process: multiple roles, persistent data, integrations (Stripe, WhatsApp, Calendar, etc.) and authenticated flows. NewMe is a good example: company HR signs up one way, employees onboard another way, and both share the same class catalog.

What types of systems can you build?+

Most common: CRMs, client portals, quote calculators, appointment systems, internal dashboards and inventory apps. If your business has a process that hurts every week, it probably fits.

How long does it really take?+

1 week for simple systems (single role, basic CRUD). 2–3 weeks for multi-role with integrations. Up to 4 weeks for platforms with payments and complex flows. We give an exact date after the 30-min brief.

Do you use no-code templates or frameworks?+

No templates. We use AI to generate the first working version fast, then human experts refine flows, integrations and edge cases. The stack is real code (TypeScript / Next.js / Postgres on the backend), not a no-code platform you can't migrate out of.

Can it integrate with Stripe, WhatsApp, Google Calendar, etc.?+

Yes. Stripe (one-time and subscriptions), WhatsApp Business (notifications and conversation flows), Google Calendar (appointments), Google Sheets, Resend (transactional email), Supabase auth — these are the most common ones we ship.

What happens after delivery if I need changes?+

You get a monthly support plan (from $100 CAD) that covers minor changes, monitoring and infrastructure. Bigger features are quoted separately. You always own the code and the data.
