Here is Michele Cimmino, I'm a software engineer and full stack developer, owner of Lasting Dynamics SRL.
I spent last 8 years building the company, studying, experimenting and refining best agile practices and keeping myself always in step with times with latest innovation and automation.
Just read your description and it seems we are the right team to create the blockchain and the platform for your saas solution.
We are SME focused on quality software development, that means we only pick few partners per year and we provide the same effort and high quality standard to all projects. Our aim is to provide a long term (lifetime) partnership and support to you. We follow a SCRUM-like agile methodology we invented ( RoundRush ) by getting best practices from all agile methodologies, following the CI/CD process and a strict QA process, using docker containers, automated tests, and a custom workflow management system we built that will soon become a JIRA competitor.
I also invite you to check my profile, as you can see there are many feedbacks, all of them are 5 stars and released for projects of 60k+

As a reference, I've been personally working not only with my 3 teams in Lasting Dynamics but also with many others from North Europe like in Copenhagen, Oslo, London and Zurich, and what I did was introduce a more productive development process that could bring the company to quickly scale up
I remain at your disposal.
Kind regards
