How we help
Four ways we can help
Most projects start with one of these. If yours does not fit, write to us anyway.
Build a new AI product
You have an idea with AI at its core. We take it from first prototype to a launched product, with quality tested and running costs worked out.
See AI services: Build a new AI productRead the Preplo case study
Add AI to your product
Assistants, search over your own data, document extraction and automation, built into the product you already run and measured on real tasks.

Build on-chain
Smart contracts, dApps and decentralized storage, shipped to mainnet. We have built on-chain products for 4+ years, on Sui, MultiversX, EVM chains, Solana and NEAR.
Ship web and mobile apps
MVPs, SaaS platforms and iOS and Android apps, from first sketch to store release, with design and engineering in one team.
Our products
Seven products of our own
We build our own products as well as yours. Running them keeps us honest about what it takes to go from idea to production, and several have won awards or funding.

What does Nano Soft do?
Nano Soft designs, builds and launches software for other companies: MVPs, AI features and agents, smart contracts and dApps, and web, SaaS and mobile apps. We go deepest in AI and blockchain, with 10+ years in software engineering and 4+ in blockchain.
We also build our own products. Kraterion, Just Add and Preplo have won awards from the Sui Foundation and RevenueCat.
Who do you usually work with?
Nano Soft works with four kinds of teams: founders who need an MVP or v1, companies adding AI to a product they already run, web3 teams and foundations that need smart contracts and dApps, and companies that want one dependable partner for web, SaaS and mobile work.
What matters more than size is a clear goal and someone on your side who can make decisions.
Do you only take AI and blockchain projects?
No: AI and blockchain are where Nano Soft goes deepest, but as a full-stack team we also build web apps, SaaS platforms, marketing sites and iOS and Android apps without either.
Many products mix them anyway. Preplo and Just Add, two of our own, are iPhone apps with AI inside, and Perqly is a web subscription business with an AI assistant.
Do you build your own products, or only client work?
Nano Soft does both: we build software for other companies, and we build our own products: Preplo, Just Add, Duskwatch, Kraterion, Inkray, Perqly and Coindrip.
Our products are the proof. We know what it takes to go from idea to production, and what happens after launch, because we do it ourselves.
Can you build our MVP, and how long does it take?
Yes, Nano Soft builds MVPs and first versions for founders, and we agree a date in the written plan before the build starts.
Timing depends on scope. For reference, we built the first version of Kraterion in about 6.5 weeks, and Preplo was built for a contest with a four-week build window. A short discovery sprint first can firm up the estimate.
How do you price a project?
Nano Soft prices each project from a written plan, so you see the cost before any build starts.
A fixed-scope build has a fixed price tied to milestones. An ongoing team works to a monthly budget you agree. A discovery sprint is a small, fixed engagement that ends with a plan and an estimate.
Who owns the code and the accounts?
When Nano Soft builds your product, you own the code, designs, documentation and accounts.
Repositories, cloud, app store and domain accounts are set up in your name or handed over to you, so you can change teams at any time without asking us for anything. We set this out in the contract before work starts.
How do we start a project?
To start a project with Nano Soft, email hello@nano-soft.tech with a few lines about what you are building, where it stands today and when you need it.
We reply within 2 working days, usually to set up a call. After the call you get a written plan with scope, milestones and cost, and you decide from there.
