Investia ICO

We are very happy and satisfied with our collaboration with Ragnarson. We were able to focus 100% on our core business as the technological stack was covered by the Ragnarson team. What I really appreciate is the clear understanding of our business needs and the preparation of non-trivial, non-standard technical solutions as a response to them. It is especially important in virgin markets, like blockchain and cryptocurrencies.

Frequently Asked Questions

What are smart contracts?

Smart Contracts are pieces of code which allow you to exchange money, shares or anything of value in a transparent and conflict free way without a middleman. Nowadays they are very often used for Initial Coin Offering (ICO).

Do you only write the Smart Contract part?

No at all. Actually, it’s the smallest and not the most complicated part. The whole process looks like this: first we give you feedback on your project idea, then we proceed to preparing a time and material quote. If you need an ICO we write the smart contact for the ICO to gather the funds. Later on we move forward to building the actual project/platform. The last phrase needs the most planning and effort.  

About our abilities to build the whole product: we are a full stack web developers with over 11 years of experience. We can do everything from front-end development, back-end development, server infrastructure to complex transactional systems. Meet our clients on our Cluch profile and Case Studies page.

I would like to learn more about how to design a token economy around my business. Can you refer me to any online resources?

Sure. We have written a ten-page document on how to design a token economy around your business, you can get it in the Case Studies section of this page.  

You might also want to check the three part blog post by Trent McConaghy from Ocean Protocol project about Blockchain and possible token use cases: Can Blockchains Go Rogue?, Towards a Practice of Token Engineering and Token Engineering Case Studies 

How do investors decide which ICOs are worth investing in?

Check out those two podcasts for understanding what red flags for investors are: a16z Podcast: Cryptocurrencies, App Coins, and Investing in Protocols and a16z Podcast: Why Crypto Tokens Matter

How do you work and which methodologies do you use?

For development we use agile methodologies, with weekly sprint meetings and frequent deployments. Here is a detailed document on how we work PDF

Do I have to come to your office or do you work remotely?

Sure, you can visit us but if you can’t that’s not a problem. We are a remote first company. We have one office in Berlin and one in Łódź.

What materials do you need from me to start? 

For giving you feedback on your idea we need to chat with you. If you have a white paper we are happy to go through it. Later on we will need wireframes or designs (list of features, layout, workflow etc.). You might want to use Invision app for that.

My product idea has a potentially huge scope with lots of moving parts. Can you help me with that?

It’s a known issue among non startup savvy people to try to do everything at once. Usually we recommend to trim the product idea to a minimum viable product (MVP), where you can test whether or not your project has a market fit without spending tons of money and wasting time. We recommend reading a great piece on Lean Startup methodology.

Do you accept tokens as a means of payment?  

No, we only accept payments in EUR or USD. 

Do you work on a fixed price or time and materials basis?

We only work on a time and materials basis.
