Accompany as a Service

We build IT Web/App
development teams

to increase your profits





In the world of IT, just as there is a word called SaaS for "Software as a Service", we'd like to introduce a new keyword AaaS for "Accompany as a Service", which comes from the idea of accompanying customers throughout development, as a service.
When read in Japanese, AaaS is pronounced as "AAAS", and adding the fact that there are three A's (ア), it would then be pronounced as "Athlee" ("l" and "r" are quite interchangeable in Japanese), thus the name of our company ATHLEE.


Together, we think of how to achieve your goals, and create solutions.

In the world of IT, there are already a lot of companies with talents who can create web applications.
However, when something needs to be created, there should always be a reason for doing so, which includes boosting revenues, increasing your brand awareness, attracting more users, or even solving certain problems.
And that is why in order to achieve a part or all of these goals, companies think of building web apps.
Requirements and specifications given out when outsourcing these projects might just do the job.
But what if these requirements and specs are not appropriate?
There are cases when not creating something is the better option.
And this is exactly why we sit down together to understand, and come up with solutions to achieve your goals.
Our IT development partners who are expert builders are ready to help us.

"Accompanying our customers"

A complete delivery of a web app or a system is only half of the journey towards achieving your organization's goals.
After development, your organization continues to answer several questions like: How do we improve the product to achieve our initial goal? How do we get know what are those improvements? Do the users think it is solving the problem? What improvements would they suggest?
These are series of processes that we strongly bear in mind when receiving IT development requests, and we feel that this is the exact meaning of "Accompanying our customers". We would like to be that company to realize it for you.

Washizu Yoshinori

He started his career as a software engineer at one of the largest game console manufacturers in Japan, and engaged in joint development of gaming technologies with local engineers in London and Silicon Valley.
After that, he joined in launching a video synthesis cloud service and became the CEO.
Since 2016, he has been mainly based in Singapore and became the CEO of a group of companies engaged in offshore development in both Singapore and the Philippines.
That same company has now grown into a 200 person organization providing services to Japan and the ASEAN region.
The group of companies have been involved in more than 1000 projects so far,and has managed everything from requirements definition all the way to implementation in collaboration with the development team.



From here onwards, more and more people become familiar with IT development and find it indispensable.
I do even think that companies and shops that have never created apps or built web-based systems for their businesses would have their custom made ones as a matter of course.


However, business owners with little to no experience in IT do have concerns in mind such as
・Whom should I consult to?
・What kind of message should I relay to a consultant?
・How do I get a quotation in the first place?
・How do I know if the quoted price is right?
・How do I compare between several quotations?
・When a job order is in place, how do I communicate my requests?
・What should I do if the product is different from my expectations?
・What about maintenance after completion?


Finding a development company is not enough. Finding a partner that will accomplish exactly the goals set for development,who will accompany business owners all throughout, is the kind of engagement that I strongly feel is necessary.
Moreover, as Japanese IT companies are required to compete with the rest of the world,it is said that the shortage of domestic IT development talents will be on a scale of nearly 1 million people in the future.
Thus, in order not to fall behind the competition on scarce IT talents,there is an urgent need to set up development bases abroad and secure development partners.


That said, there is a pile of uncertainties mounting over businesses such as:
・Can we manage foreign engineers located overseas?
・Which country could be the best fit for us?
・How do we setup development bases abroad?
・How do we recruit and train local engineers?
It is my strong opinion that even global corporations need help in tackling these challenges.
And we would like to support you in addressing these issues.
