B2B SaaS Development from A to Z

SaaS B2B Development

Want to launch your B2B SaaS but don't have a tech team?

My approach: everything starts with a scoping interview

During our first scoping interview, I'll first assess with you, based on your skills, project progress, and budget, whether diving into code is a good idea. Developing a SaaS with code requires on one hand a substantial budget, and on the other hand the ability to manage and maintain the application after the mission is complete. This necessarily implies either hiring internally, using a service provider, or taking charge yourself if you can.

If I determine that your best interest is to develop an MVP without code, I'll connect you with a no-code expert.

There are generally two possible paths in SaaS development missions, and we'll need to decide between them from our first meeting based on your needs.

  • Either you're in a hurry, and speed is your main criterion. In this case, I'll do everything possible to deliver as quickly as possible. In this situation, certain aspects will be compromised, particularly the level of user interface customization, the presence of regression tests, and design choices that will be less optimized for performance and scalability. However, there are certain points I never compromise on regardless of the situation, primarily security and data protection, as well as data reliability.
  • Or you want high quality, without compromise. In this case, I'll deliver a high-end application with all development best practices.
