It is 11th of June 2018 today. This review takes into consideration investing in Leonardian (LEON) – ICO at a price of 2000 per ETH(which could be a lot lower, read below).

We do not endorse the ICO’s we are writing reports on – we just have a big pile of ICO’s that people have mentioned to us could be worth taking a look at and we are going through them one by one. All shared personal statements are a personal point of view.


Short description of the project:

Leonardian is a blockchain based marketplace which connects directly service providers offering digital or freelance services with potential customers. The major problems other marketplaces have are that they mainly offer either products or freelance services, where the customers often need supporting services to help them properly use them, maintain them and mold to their individual needs. Other key features are lower fees, instant payments, strict quality assurance, refunds and randomized algorithms that allow new sellers to be able to be discovered.


In-depth project overview:

I really like seeing a project that wants to tackle a specific pain. Leonardian has a specific in front of them – to allow the customer have an encompassing solution to their need and the service provider to receive their reward securely and in a timely manner.  Another thing that I also like seeing is a professional team with a realistic timeframe.  With so many developers that have years and years of experience, the set goals of releasing a beta version end of Q1 next year, should be achieved.

Software purchases are expected to reach 389 billion USD until the end of 2018 and IT services are evaluated to 985 billion USD, so the market for both is huge and the trend is upwards. With this expanding market the team has identified several major problems and has come up with the solutions for them:

  • High fees – Some marketplaces take 30-70% from the revenue from a sale, where the team offers a set fee of 8%.
  • Delayed payements – The payment after a sale arrives after 15-45 days, with the help of blockchain the payments are being made instantly.
  • Biased algorithms – Other marketplaces promote the top sellers and the new ones struggle to get an audience. Leonardian will have an algorithm that shows sellers on a random basis, giving equal chance to be spotted.
  • Product approvement – Products that are to be reviewed by a marketplace can take a long time to be reviewed and without specific guidelines and a subjective approach the process can be unpleasant for the seller. The Leonardian marketplace will have a system for quality assurance where the product is being reviewed by a person and by an AI-powered algorithm.

The reviews of products will be assigned also randomly and anonymously to QA’s with knowledge in the specific domain of the product, who perform their checks following strict rules. The reviewer receives a payout which depends on the difficulty of the task, the time needed for the review, the speed of completion of the task and rating of the reviewer.

The rating of the reviewer is being made from 0-100 and is being decreased if there are grounded disputes resulting in a refund, a big discrepancy between the score of their manual review and the score from the AI(where an reviewer will have to step in) and a delay of delivery. The rating determines how many tasks you can get.

Also buyers, sellers and the products themselves can be rated according to their performance.

A dispute can be made if the two sides do not come to an agreement within 5 days. It goes to a mediator, who is a reviewer with a very high score, who has 3 days to resolve it.

The seller has a deposit in the system, which guarantees that he will provide quality products. This deposit is higher if the seller has a lower rating, has few sales or resolves dispute (if there were such) slowly. This deposit is withdrawable if the seller closes their account (if there are no pending disputes).

In the situation of a closed account or the disputed sum is bigger than the deposit of the seller this will be taken care of through the funds in the Fee Pool.

The Fee Pool itself will be split as follows: Future Development and Marketing 30%, Angels Annual 20%, Quality Assurance 20%, Other Operational 20%, Disputes 10%.

Angels are investors that have more than 10,000 tokens. They receive an annual incentive for holding the token. If they have more than 25,000 tokens they get 1 vote that can be used for steering where the platform should go development wise and a single investor cannot have more than 10% voting power.


Here is the budget allocation: marketing & business development 40%, development 30%, operational costs 15%, legal, accountant, compliance, regulatory 10% and unforeseen costs are 5%.

Here is the token allocation: liquidity of the system 40%, the token sale 50% and 10% for the team and advisors, which is quite on the low side!

The transactions will be done directly from customer to services offeror and vice versa. No intermediaries. The blockchain ensures secure and timely payments. But there can be also payments in different cryptocurrencies, PayPal and other payment options.

The transactions on the platform will be done with LEON tokens, but balances can also be withdrawn in different cryptos.

Website: does it look good/presentable:  really like the how the website looks, colors and overall appearance, has all the needed information on it.

Website – https://leonardian.com/

Roadmap –Directly on the website in the top menus.

Whitepaper – Also directly on the website in the top menus. I really like a well-structured whitepaper that makes sense. No unneeded information.

How does the cryptocurrency name sound (does it sound legit and like a good brand name) – The name is awesome, I love the academic atmosphere and you can sense it here. Leonardo da Vinci was a remarkable scientist and inventor.

How does the logo look – The logo is really simple but says many things.  Da Vinci’s Vitruvian Man, read about it if you do not know!

Who is behind the cryptocurrency, are they shady figures, or have they placed their names and pictures on the website; what is their track record and reputation – The CEO, Kristyan Lozanov, has had many years of experience in IT and people and project management. The rest of the team also looks solid with many years of experience. Quite the tech team!

What is the limit on supply of coins in circulation – Total token supply will be 263,000,000 LEONs.

What the project survival relies on – Providing a good product that does what is supposed to do and making it grow so more people can join. The demand for their work is there.

Will this project survive a cryptocurrency bubble burst and does/will it have enough of a following that needs it every day – if they establish themselves solidly on the market, it looks so, and the ability to pay in fiat is helpful.
