Evolve your mature SaaS solutions
WakaStart supports mature software publishers whose solutions are already deployed on a large scale and who must now meet reinforced cybersecurity, compliance and maintainability requirements.
In an increasingly restrictive regulatory context, the challenge is not to start from scratch, but to develop the existing system towards a secure, compliant and sustainable platform.
When maturity imposes a new level of requirement
Legacy publishers have proven solutions, but ISO 27001, NIS2, and 2026 cybersecurity requirements make a comprehensive review of the code and architecture essential.
A simple update is not enough. WakaStart offers a structured approach to rewrite and modernize the solution while maintaining existing functionalities and uses.
A tailor-made approach, adapted to complex solutions
The budget and the schedule are therefore tailor-made, according to several criteria: number of applications to be used, code volume, number of modules, functional specificities and technologies involved.
In the case of a single application deployed by multiple customers, an estimated budget of €10,000 per month over 12 months constitutes a working basis. This framework is then refined according to the real complexity of the project, the number of screens, functional richness or specific technical constraints.
A gradual and controlled rewriting
The objective is to completely rewrite the legacy solution over a period of between 5 and 20 weeks, depending on the complexity of the project, in order to allow operational implementation in a maximum of 6 months.
This approach guarantees functional continuity while securing the transition to the new version.
The project plan necessarily involves the partner publisher's teams:
for writing and reviewing technical specifications,
for functional validation,
for the test phases,
and for gradual deployment to existing customers.
A work of partnership
The objective is not to create a dependency, but on the contrary to allow legacy publisher teams to take back control of application management, support and product evolution once the transition has been made. WakaStart is here as a technological partner, at the service of the sustainability of the solution. The budget of €10,000 per month for 12 months covers:
The rewrite
complete solution
The upgrade
ISO 27001 compatible security
The follow-up
security updates
The fixes
linked to the first developments over the period
Post-transition accommodation and operation
At the end of the first 12 months, a Legacy Hosting Pack takes over for a period of 12 months, renewable each year.
Complementary development or recipe environments can be set up on demand, according to the needs of the publisher.
A clear framework for mature publishers
Project milestones are precisely defined to ensure a controlled transition. Each stage meets measurable criteria and validated deliverables.
Rewrite time
maximum depending on the complexity, global implementation up to 6 months
Monthly payment
per month for 12 months
Lodging
included in the monthly payment
