Most businesses don't need 10 different agencies they need one team that can handle everything. At FIZNEX, that's exactly what we do. From websites and mobile apps to AI tools and blockchain platforms, here's a complete look at every service we offer and how each one helps your business grow.
FIZNEX is a full-stack custom software development agency. Since 2021, we've built products across web, mobile, AI, and blockchain for clients in the US, UK, Canada, and Europe. Whatever stage you're at, there's a service here that fits.
Web Development
Your website is often the first thing a customer sees, so it needs to be fast, clean, and built to convert. We build custom websites and web apps from scratch business sites, online stores, booking systems, dashboards, and CRMs.
Every site is responsive, fast-loading, and SEO-friendly, so it looks great on any device and ranks higher on Google. You also get an easy admin panel to manage everything yourself, plus optional AI features like 24/7 chatbots and smart search.
Mobile App Development
We build mobile apps for both iPhone and Android from a single codebase, using React Native and Flutter. That keeps your costs lower and your launch faster no paying twice for two separate apps.
From food delivery and booking apps to social and fitness apps, we handle login, push notifications, in-app payments, maps, and real-time features like live chat and video calling. You also get an admin panel to manage everything.
Here's what makes our process different: we send you regular Loom video updates so you can see the progress with your own eyes, and we test every app on real physical devices not just emulators so it works perfectly before launch. You get full video proof, start to finish.
AI Integration & Chatbots
AI isn't the future anymore it's how smart businesses run today. We build custom AI chatbots and assistants powered by GPT-4, Claude, and Gemini.
We connect the AI to your own data your documents, FAQs, and products so it answers accurately about your business (this is called RAG). We also build sales assistants, voice agents, and automation that connects to WhatsApp, Slack, and your CRM.
SaaS Development
Got a software idea you want to sell as a subscription? We build complete SaaS platforms from the ground up from a quick MVP to a full product ready for thousands of paying users.
This includes user sign-ups, subscription billing with Stripe, pricing plans, team accounts, and a powerful admin dashboard. Everything is built on secure, multi-tenant architecture so it scales smoothly as you grow.
Blockchain & NFT Development
We've been building on Solana and Ethereum for years. If your project lives in Web3, we know this space deeply.
We create NFT marketplaces, minting websites, smart contracts, token launches, staking platforms, and full crypto apps. We connect wallets like Phantom and MetaMask, and write secure, audited contracts that handle payments and royalties automatically.
NFT Art & Collection Design
Beyond the code, we also design the art. For NFT projects, we create eye-catching collections ready to launch.
This covers custom characters, avatars, and PFPs, plus full generative collections with thousands of unique pieces and rarity levels. We design in 2D and 3D and deliver mint-ready files with all metadata included.
CRM & Business Software
Off-the-shelf software rarely fits the way you actually work. We build custom CRM and business tools shaped around your exact process.
From lead and sales tracking to inventory, invoicing, booking, and HR tools we replace messy spreadsheets with one clean dashboard. We can also add AI for automatic follow-ups, smart reports, and payment reminders.
DevOps & Cloud Management
A great app means nothing if the server keeps crashing. We handle the setup, security, and smooth running of your servers on VPS, AWS, and DigitalOcean.
This includes auto-deployment on every code push, CI/CD pipelines, Docker, SSL, and domain setup. We harden your server with firewalls and 24/7 monitoring, and recover crashed or hacked servers when needed.
Bug Fixing
Something broken and need it fixed fast? We fix bugs on websites and apps often within 24 hours.
We handle crashes, white screens, slow loading, login and payment errors, API failures, and even App Store or Play Store rejections. We find the root cause so the same bug doesn't return and you don't need to have built the project with us.
App Publishing
Getting an app approved on the App Store or Play Store can be confusing. We take care of the entire publishing process for you.
Don't have a developer account yet? No problem we help you set up both accounts the right way. We prepare your store listing, icons, screenshots, and compliance forms, then submit your app. If it gets rejected, we fix and resubmit until it's live.
