Your SaaS already exists.
So do your customers.
The stakes are different.

You have a live product, a team, and customers relying on you. WakaStart rebuilds your architecture without interrupting your service — and certifies your SaaS ISO 27001 in 1 to 3 months.

The signs don't lie

Your SaaS works.
But something's stuck.

These situations sound familiar. They don't disappear on their own — they get worse. And they hold back your growth at a critical moment.

A key account is asking for ISO 27001

Your prospect's CISO halts the deal. Without certification, you can't sign. And your current architecture isn't certifiable as it stands.

Your developers spend 80% of their time on maintenance

They fix bugs, patch vulnerabilities, handle incidents. They're no longer innovating. Technical debt piles up, and every fix introduces a new one.

Performance degrades as you grow

The architecture wasn't built to scale. One big new client and the SaaS grinds to a halt. You dread traffic spikes instead of welcoming them.

Your tech stack is outdated or unreadable

Ageing PHP, monolithic Java, a spaghetti of dependencies. Every hire becomes difficult. Every change takes three times longer than planned.

Your on-premise clients are asking for SaaS

Your software is installed on your customers' premises. They now want a cloud version, updated automatically. But your architecture doesn't allow that without a full rebuild.

NIS2 is blocking your contract renewals

Since January 2026, your key account clients are themselves subject to NIS2. They're asking you for proof of compliance. You can't provide it.

For your profile

WakaStart adapts
to your actual situation.

SaaS scale-up

Growing SaaS showing its technical limits

Architecture that doesn't scale — one big client and everything slows down
ISO 27001 is blocking key accounts
Developers drowning in reactive maintenance

Full rebuild + ISO 27001 in 1-3 months. Zero downtime. Your developers upskill on the Waka stack.

On-premise vendor

Software installed at customer sites, stagnating revenue

Customers wanting cloud SaaS with automatic updates
Perpetual licence model in decline
Impossible to guarantee security in client environments

Migration to cloud SaaS with gradual coexistence. Your on-premise clients migrate at their own pace — with no service disruption.

Enterprise / CIO

Sprawl of heterogeneous SaaS, unsecured legacy systems

Legacy Java/COBOL/.NET systems — costly to maintain
NIS2 requires urgent compliance across the whole chain
Full rebuild too risky, too costly

Coexistence with legacy systems. We start with new peripheral developments, then modernise module by module — with no risk of downtime.

The WakaStart method

We don't reinvent your product.
We industrialise it.

WakaStart migration follows a rigorous 3-phase process. Each phase is validated before moving to the next — zero possible regression, zero surprises for your customers.

Preliminary phase — Free audit

Cognitive reverse engineering

Our AI agents analyse your existing code, screens, user journeys and documentation. They produce a complete functional and security specification (FSS) of your current SaaS — even if your documentation is missing or outdated. You finally recover the "truth" of your product, formalised and usable.

AI + CISO · Existing code audit · 48-72h
Phase A — 1-to-1 transposition

Regeneration with identical functionality

Your SaaS is regenerated on the Cybercoding architecture — feature by feature, behaviour by behaviour. Comparative automated end-to-end tests confirm that every screen, every flow, every business rule is strictly identical. No functionality disappears. Your customers see nothing. We never move to Phase B until Phase A is 100% validated.

1-to-1 tests · Zero regression · Customers unaffected
Phase B — Enhancements and new features

Your SaaS moves forward, cleanly

Once the base is sound, stable and certifiable, we integrate the new features you were never able to deliver — either because technical debt prevented it, or because your developers didn't have the time. Each enhancement is generated atomically, tested and deployed with no risk.

New features · ISO 27001-certifiable

Migration guarantees

Zero service interruption

Your customers keep using your SaaS throughout Phase A. The switchover happens live — invisible to your users.

Zero data loss

Data migration with a full rollback plan. Every step is reversible until the final validation of Phase A.

Fixed price — controlled budget

Unlike a consultancy's day rates, WakaStart commits to a fixed price. You know from the outset exactly what it will cost — and it won't go over.

ISO 27001 within the following month

A direct extension of our COFRAC scope. The auditor is known, the process is proven. Within 30 days of going live, you're certified.

Your code belongs to you

100% your property from day one. Nest.js / Next.js — universal standards, zero technology lock-in.

"WakaStart made it possible to entirely reinvent the Documalis solution, whose ageing architecture no longer met the new requirements imposed by the NIS2 directive."

Your teams

We don't replace
your developers.
We free them up.

Your developers' first question will be: "Is WakaStart here to take our place?"The answer is no. And here's why that's not just talk.

We work with your team, not instead of it

Your developers take part in the specification and validation phase. They know your business better than anyone — that knowledge is irreplaceable, and we need it.

We upskill them on Waka standards

Nest.js, Next.js, Kubernetes, Keycloak, GitOps — skills in high demand on the market. Your developers leave the project with a stronger technical toolkit than when they started.

We free them from reactive maintenance

No more spending 80% of their time on fixes and incidents. With Cybercoding, your developers focus on what they're meant to do: create business value and new features.

Before WakaStart
With WakaStart
80% of time on reactive maintenance and bug fixing
80% of time on new business-value features
Every fix potentially introduces a new vulnerability
Clean major releases through quarterly atomic generation
Outdated stack — hiring difficulties, tech frustration
Modern Nest.js/Next.js stack — skills valued in the market
Production incidents at night, firefighting weekends
24/7 monitoring by the WakaStart team — peace of mind restored
Unreadable code — only the person who wrote it understands it
Clean, documented, auditable code — anyone can pick it up

To take the conversation further

Your developers have doubts.
That's normal. Here's how to answer them.

Any major change creates resistance — out of caution, habit, or sometimes pride in the work already done. These objections are legitimate. They deserve honest answers.

What your developers are thinking

The real objections — and the real answers

They're going to rewrite my code — that must mean I did a bad job.

No. Technical debt doesn't mean you did a bad job — it means you delivered under time and budget pressure, like every developer does. WakaStart doesn't judge your past code. It analyses it objectively and regenerates it with resources you didn't have: a forge of coordinated AI agents, a dedicated CISO, an industrial security framework. It's a step up, not a judgement.

An AI can't understand the business logic I built over 3 years.

Exactly — that's why we need you. The reverse-engineering phase is carried out with you, not without you. Your knowledge of the business logic is irreplaceable. The AI analyses the code and interfaces — you confirm the understanding is correct. Only then do we generate. It's collaborative work, not a replacement.

After the migration, there won't be any work left for me.

Quite the opposite. The migration frees up time for what you've never had time to do: the new features your customers have been asking for for months, the UX improvements you've had in mind, the integrations the market expects. With a healthy base and no more daily reactive maintenance, you'll have more value to create, not less.

I don't know Nest.js / Next.js. I'll be lost.

WakaStart trains your developers on the stack during the project. Nest.js and Next.js are the most sought-after standards on the market in 2026 — mastering these technologies significantly boosts your value in the job market. No one leaves a WakaStart project less skilled than when they arrived.

What you can tell your developers

The arguments that unlock the conversation

"We're not changing your role — we're changing your working conditions"

You'll remain the business and product experts. WakaStart handles the generation, testing, security and deployment. You focus on vision and value — not Sunday-night incidents.

"Technical debt isn't your fault — letting it grow would be ours"

Every team that delivered fast created some debt. It's not an individual failure. But continuing to patch instead of rebuilding means collectively choosing to stay stuck — and that's what puts the company at risk.

"You'll gain skills that are highly valued on the market"

Nest.js, Next.js, Kubernetes, Keycloak, GitOps — these are the skills CTOs are looking for. By the end of the project, you'll have practised a level of industrialisation no consultancy would have offered you.

"Your business knowledge is our advantage — not the AI"

AI generates clean, secure code. But it doesn't understand why this client needs a special billing rule, or why this business flow is counter-intuitive. That knowledge is you. And it's essential.

"If we lose this contract because of ISO 27001, everyone's job is at risk"

Concretely, directly. A lost key account due to compliance can represent 30 to 50% of revenue. The WakaStart migration is a matter of commercial survival — not a technology luxury.

Zero downtime

Your customers see nothing.
That's the rule.

The WakaStart migration is designed so that your existing customers experience no interruption, no service degradation, no data loss. It's an absolute constraint, not a goal.

Your questions

We answer honestly.

Does WakaStart replace my development team?

No. WakaStart works with your team, not instead of it. Your developers take part in the specification phase, validate the reverse engineering, and upskill on Waka standards (Nest.js, Next.js, Kubernetes). After the migration, they move from time spent on reactive maintenance to time spent creating business value — what they're there for.

Will my customers be affected during the migration?

No. The migration runs in two parallel phases — Phase A (identical functional transposition) then Phase B (new features). Your customers keep using the old version throughout Phase A. The switchover only happens after full validation of the 1-to-1 tests. A rollback plan is in place at every step. The migration is invisible to your users.

How long does a WakaStart migration take?

1 to 3 months for a scale-up or a standard SaaS vendor. ISO 27001 certification follows within the month after going live. For large organisations with complex legacy systems (Java, COBOL, .NET), the migration is gradual and spans several years — module by module, with no business disruption. Our free audit lets us precisely estimate the timeline for your situation.

Our code is complex and poorly documented. How will you find your way around it?

That's exactly 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 and security specification of your SaaS as it actually behaves today. Your developers then confirm the understanding is correct. It's often the opportunity to re-document a product no one fully understood any more.

What does a WakaStart migration cost?

From €30,000 excl. VAT, spread out with no bank loan needed — instalments from €2,000/month. The actual budget depends on the complexity of your existing SaaS — start with our free audit to get a precise estimate within 48h. WakaStart commits to a fixed price: no runaway day rates, no budget overruns.

We have on-premise software installed at our clients' sites. How does this work?

The migration to cloud SaaS happens gradually. Your existing on-premise clients migrate at their own pace — they keep using their local installation while the cloud SaaS version is validated. For clients with absolute physical isolation requirements (defence, healthcare, finance), WakaStart offers on-premise deployment on your own infrastructure, with the Cybercoding Control Plane maintaining consistency via GitOps.

Your SaaS has survived
its growth.
Now, make it thrive.

Start with our free audit. Our Lead Dev and CISO analyse your existing code, identify the blockers and hand you a migration plan with a fixed timeline and budget. Within 48h, you'll know exactly where you stand.
