You have customers in production, an established MRR — and an architecture showing its limits at the exact moment you need it most. WakaStart rebuilds your SaaS without interrupting your service, and delivers it ready for ISO 27001 certification in 3 to 4 months.
What you're experiencing right now
A scale-up that stalls technically doesn't only stall technically. It loses contracts, slows down its team, and accumulates debt that will cost 10 times more to fix in 18 months.
A major account is blocking renewal
Your strategic customer's CISO demands ISO 27001 before resigning. Without the certificate, the contract — and the €50,000 of associated MRR — is at stake.
One big customer = the SaaS grinds to a halt
As soon as a high-volume account connects, performance degrades for everyone. The architecture wasn't designed to scale — and it shows.
80% of dev time = maintenance
Your developers are fixing bugs instead of creating value. Every fix introduces a new one. The product backlog has stopped moving.
Vulnerabilities found in the pentest
The security audit commissioned by your board has revealed structural vulnerabilities. Insufficient IAM, exposed secrets, non-compliant logs. The report is on your desk.
NIS2 is blocking new deals
Since January 2026, your enterprise prospects have received internal directives: every SaaS provider must be NIS2-compliant. Without proof, you're excluded from tenders.
Impossible to rebuild alone
Your team is fully committed to maintaining the existing product. A parallel rebuild would require doubling headcount, 12 months of work — and would risk service continuity for your current customers.
The most common scenario
"Are you ISO 27001 certified? Our CISO is blocking the signature until we have the certificate."
This sentence comes up in our customers' testimonials every two weeks. A contract worth €40,000 to €100,000 of annual MRR — blocked not by product quality, not by price, but by the absence of a certificate that a traditional IT services firm would have taken 18 months to obtain for €150,000. With WakaStart, it takes 3 to 4 months to deliver a certification-ready SaaS — at a fraction of the cost.
Real customer case
An HR sector SaaS scale-up. Solid product, established customer base, steady growth — but an architecture built quickly to get to market that was starting to show its limits at the worst possible moment: a major account had just blocked renewal due to the lack of ISO 27001 certification.
The situation was typical for a scale-up of this age: the architecture had been built for speed, not to last. Multi-tenant isolation was insufficient, API secrets were hardcoded, and audit logs didn't meet ISO requirements. And on top of that — a recent pentest had flagged 4 critical vulnerabilities. The free audit produced the diagnosis in 48 hours: a 4-month rebuild plan, fixed price, zero service interruption guaranteed. Phase A reproduced the entire product identically on the Cybercoding architecture while customers continued working normally. Phase B delivered the features that had been waiting in the backlog for 8 months. One month after going live, the SaaS was delivered ISO 27001-ready. The major account resigned straight away. Three new enterprise deals followed within 6 months.
"We were afraid of breaking everything during the migration. In fact, our customers noticed nothing. And our devs finally spend time on features instead of patching bugs."
The WakaStart method
We read your code. You know where you stand.
Our Lead Developer and our CISO analyse your existing source code. Within 48 hours, you receive: a map of vulnerabilities, areas of architectural fragility, and a rebuild plan with a fixed timeline and budget. Not an estimate. A precise quote based on the reality of your code.
Free · 48 hours · No commitmentYour product regenerated identically. Your customers see nothing.
The AI analyses every screen, every flow, every business rule of your existing SaaS. It produces complete functional and security specifications — even without documentation. It then regenerates your SaaS on the Cybercoding architecture, feature by feature. Automated 1-to-1 tests guarantee no regressions. Your customers keep using the old version throughout Phase A.
1-to-1 tests · Zero regression · Customers unaffectedWhat you could never deliver. Now possible.
Once the sound foundation is validated, we integrate the features that technical debt had prevented you from shipping for months. Reinforced multi-tenancy, new integrations, WAKA-SIGN or WAKA-DOC modules. Without any risk of breaking what already exists. Every enhancement goes through the full Cybercoding pipeline.
Sound foundation · Risk-free enhancementsISO 27001-ready. The stalled deal can be signed.
Your SaaS emerges from the rebuild with ISO 27001 rules built in natively — documented ISMS, compliant audit logs, access segregation, secrets management. The subsequent auditor certification (COFRAC) is therefore much faster and more predictable. You have complete audit documentation, ready to present to any prospective CISO.
ISO 27001-ready · NIS2 native · Complete audit documentationWhat we guarantee contractually
Zero service interruption
Your customers use your SaaS throughout Phase A. The switchover is invisible. A rollback plan is in place at every step.
Fixed price — controlled budget
No runaway day rates. You know the figure before signing. It won't be exceeded — guaranteed contractually.
Your teams stay — and level up
WakaStart works with your developers, not instead of them. They upskill on Nest.js, Kubernetes, Keycloak — and move from curative maintenance to value creation.
Code 100% your property
Nest.js / Next.js — universal standards. Zero technology lock-in. IP transferred from day one.
What this actually changes
The real conversation to have
Every rebuild triggers resistance — out of caution, habit, or sometimes pride in work accomplished. These questions are legitimate. They deserve honest answers.
What your devs think
They're going to rewrite my code — that means I did a bad job."
Technical debt doesn't mean the work was done badly — it means it was delivered quickly under constraints. WakaStart doesn't judge your code. It analyses it objectively and regenerates it with resources you didn't have: an AI agent forge, a dedicated CISO, an industrial framework.
An AI can't understand our business logic."
That's exactly why we need you. The reverse-engineering phase is done with your team, not without it. Your business knowledge is irreplaceable. The AI analyses the code — you validate that the understanding is correct.
After the migration, there'll be no more work for me."
On the contrary. The rebuild frees up time for the features you've never been able to deliver — the ones your customers have been asking for for months. With a sound foundation, you create value instead of patching bugs.
What you can tell them
“We're not changing your role — we're changing your working conditions."
You remain the business and product experts. WakaStart handles generation, testing, security and deployment. You focus on the vision — not on Sunday-night incidents.
“You'll gain skills that command a high price in the market."
Nest.js, Kubernetes, Keycloak, GitOps — the most in-demand skills of 2026. No one leaves a WakaStart project less skilled than they arrived.
“If we lose this contract, everyone is affected."
Losing a major account over compliance can represent 30 to 50% of revenue. The WakaStart rebuild isn't a technological luxury — it's a matter of commercial survival.

What this budget doesn't include — unlike an IT services firm.
No runaway day rates
An IT services firm bills you by the day with no commitment to results. WakaStart commits to a fixed price — the figure doesn't move after signing.
No separate €150k ISO project
Certification is included in the package. Our COFRAC scope extension in 30 days — not a standalone project.
No need to hire DevOps or a CISO
The WakaStart Run team includes 24/7 monitoring, updates and incident management — without additional payroll.
No bank loan
The spreading is backed by our holding company JDS Conseil. Your balance sheet isn't affected. No personal guarantee required.
Your questions
Will my customers be affected during the migration?
No. The migration happens in Phase A (identical functional transposition, validated by 1-to-1 tests) before any switchover. Your customers keep using the old version throughout this phase. The switchover happens live, after full validation, invisibly. A rollback plan is in place at every step — nothing switches over without a safety net.
Our code is poorly documented and complex. How will you find your way around it?
That's precisely why cognitive reverse engineering exists. Our AI agents analyse the source code and interfaces — even without documentation, even with ageing code. They produce the functional specification of your SaaS as it actually behaves. Your team then validates it. It's often the opportunity to re-document a product that no one fully understood any more.
How long does the rebuild take?
3 to 4 months for a standard scale-up. The free audit lets us precisely estimate the timeline for your project within 48 hours. For more complex projects (numerous business modules, ERP integrations, high data volume), the timeline can be 5 to 6 months — with the same guarantee of zero service interruption.
Does WakaStart replace my development team?
No. WakaStart works with your team, not instead of it. Your developers take part in the specification phase and validate the reverse engineering — their product knowledge is irreplaceable. After the rebuild, they upskill on the Waka stack (Nest.js, Kubernetes, Keycloak) and move from curative maintenance to business value creation.
How much does a WakaStart rebuild cost?
From €55,000 excl. VAT for a scale-up, spreadable without a bank loan with instalments from €3,000/month over 36 months. This package includes reverse engineering, the full rebuild, and ISO 27001 preparation natively integrated as an option. Start with the free audit — you'll get a precise figure based on your actual code within 48 hours, with no commitment.
What if our SaaS evolves during the rebuild?
Phase A reproduces the existing product identically — it isn't affected by ongoing changes. New features are integrated in Phase B, on the sound foundation, using the same Cybercoding pipeline. Your product roadmap isn't put on hold during the rebuild.
Start with the free audit — a free 48-hour review of your code. Our Lead Developer and our CISO analyse your architecture, identify the blockers and hand you a rebuild plan with a fixed timeline and budget. No commitment.
