Case Studies
Software case studies from a team that ships
These are the products SpaGreen Creative has designed, engineered and launched end-to-end — from WhatsApp marketing SaaS and multi-vendor eCommerce to OTT streaming platforms, learning systems and courier dispatch software. Every case study below documents the real challenges, the architecture we chose, the team we deployed and the measurable outcomes our clients hit after launch.
Whether you’re hiring a software development company, validating a SaaS idea, replatforming a legacy product or scoping your next custom build, use these stories to benchmark scope, timeline and stack decisions against teams that have already solved similar problems.

How SpaGreen turns a brief into a shipped product
Every case study on this page followed the same predictable 4-stage playbook — the same one we’ll use on your project. No billable-hour surprises, no junior devs hidden in the team.
Discovery & scope
NDA-protected workshops, user stories, data model and a fixed-price proposal you can lock in.
Design & build
Senior product engineers ship weekly demos. You see, test and steer the product every Friday.
Harden & launch
End-to-end tests, load testing, security review, observability and a clean production cut-over.
Grow & scale
30-day free warranty, retainer plans and infra cost reviews so the product compounds after launch.
Buyer FAQ — how to evaluate a software case study
The questions buyers most often ask before commissioning a project from SpaGreen Creative.
Eleven detailed case studies covering WhatsApp marketing SaaS (SaleBot, WhatsAble, Rapiwa), multi-vendor eCommerce (Yoori), OTT and video streaming (Flixoo, OXOO, OVOO), online learning (Faculty LMS), video conferencing (MeetAir), IT asset management (ITNOW) and courier and logistics dispatch (Delix). Each case includes scope, team, stack, timeline, challenges and measured outcomes.
Look past the screenshots and check four things: (1) the team composition — were senior engineers involved or only juniors; (2) the architecture — multi-tenant, scalable, secure; (3) timeline transparency — were milestones met; (4) measurable outcomes — uptime, conversion, cost-per-tenant, time-to-market. SpaGreen case studies disclose all four.
Yes. Each case study on this page reflects a battle-tested architecture template we can re-deploy with your branding, features and integrations. Most clone-style builds ship in 6–12 weeks; custom variations take 12–26 weeks depending on scope. Every project begins with a fixed-price discovery sprint.
Fixed-price MVPs start at $7,500 USD. White-label re-deployments of an existing case study (Yoori, OXOO, Flixoo, SaleBot) start at $4,800 USD. Enterprise-grade platforms with SSO, SOC 2 readiness, dedicated DevOps and custom integrations are scoped on proposal. You always get an itemised quote — never hourly surprises.
You do — 100%. SpaGreen signs your NDA before discovery, and you receive full ownership of source code, Figma files, cloud infrastructure access and documentation as each sprint is paid. No code escrow, no lock-in.
Metrics published on case study pages are based on telemetry from live deployments and aggregated where multiple clients use the same product (e.g. Yoori, OXOO, Flixoo are sold to many businesses). Specific brand attributions are made only with written client consent.
Retail and eCommerce, media and OTT, telecom and messaging, logistics and courier, IT services, EdTech, real estate, healthcare and B2B SaaS. Our clients range from solo founders to enterprise teams in 110+ countries.
Discovery starts within 5 business days of contract signing. MVPs typically launch in 8–12 weeks, white-label re-deployments in 6–10 weeks and full custom platforms in 14–26 weeks. Every sprint ends with a working demo and changelog you can forward to investors or your board.
