Serdao is a France-headquartered IT support and custom software development vendor with Vietnamese delivery, and it has spent nearly two decades building a loyal client base in the European market. If you're a European company that needs managed support coverage, end-to-end web delivery, and a single vendor to handle both, Serdao is worth a serious look. If you're a US-based engineering leader trying to hire AI-native product engineers on a flexible basis, it's probably the wrong conversation entirely.

Serdao operates as an outsourced IT and software delivery firm, not a talent marketplace or a staff-augmentation platform. Its model is closer to a managed services provider: the client contracts with Serdao for a body of work or an ongoing support function, and Serdao's Vietnam-based delivery team executes. The French headquarters gives European clients local-language sales and contracting, while the offshore team provides cost leverage. The company claims 96% customer loyalty across 18 years of operation. That's a number worth taking seriously. Managed service vendors live and die by renewal rates, and sustaining that kind of retention over nearly two decades signals genuine operational discipline, not just clever marketing.

The clearest picture of Serdao's positioning comes from its public content strategy. The blog covers a wide range of technical and operational ground: custom web development, ticketing and support system architecture, front-end interactivity and dynamic web patterns, and software development tooling including CI/CD, container orchestration, and serverless deployment. That breadth is deliberate. It tells you Serdao is positioning as a full-service vendor capable of owning the entire conversation from discovery through support, not just a specialist shop. For a European SME that wants one vendor to handle everything from a new customer portal to the helpdesk that runs underneath it, that end-to-end coverage is genuinely attractive. The 24/7 support coverage is a real operational capability. Staffing firms and marketplaces don't provide this. When you hire an engineer through a marketplace, that engineer keeps their own hours. Serdao's managed model means the lights stay on regardless of who's working the shift.

End-to-end delivery coverage. Serdao demonstrates fluency across the full stack: custom web development, front-end interactivity, deployment infrastructure, and IT support. A client who needs all of that under one contract doesn't have to manage multiple vendors or stitch together a hiring pipeline. That simplicity has real value, especially for teams without a strong internal engineering function. 24/7 operational support. The managed model means Serdao can provide continuous coverage, something no marketplace or staffing firm promises. For companies running customer-facing systems where downtime has a direct revenue cost, that's a meaningful differentiator. European market fit. A French headquarters with Vietnamese delivery is a smart structural choice for European clients. Local language, local contracting, local business hours on the sales and account side, with offshore cost structures on the delivery side. This model has worked for 18 years because it solves a real pain point for mid-market European companies. Loyalty and tenure. A 96% customer loyalty rate over 18 years is not an accident. It reflects that Serdao's clients find enough value to keep renewing. In a market full of vendors who over-promise and under-deliver on outsourcing engagements, that track record stands out.

The minimum contract term is one year. That's appropriate for a managed services relationship, where Serdao needs time to staff, onboard, and stabilize delivery. But if your roadmap is shifting quickly, if you're scaling up a new product line, if your engineering priorities might pivot in Q2, a twelve-month minimum creates friction. The model rewards stability, not speed. The center of gravity is support and managed delivery, not product engineering. Serdao's public positioning emphasizes web development and IT support, which are execution-oriented disciplines. If you need someone who can own an architectural decision, drive a technical roadmap, or build AI-native product features from scratch, a managed delivery vendor is structurally different from embedding a strong product engineer on your team. These are different jobs, and the engagement model reflects that. The delivery team is Vietnam-based. For European clients, this typically works well because the time zone gap is manageable and the French headquarters handles relationship continuity. For US-based engineering leaders, the overlap with Pacific or Eastern working hours is limited, and the firm's entire contracting and account infrastructure is oriented toward the European market.

Here's what Serdao leaves you to figure out on your own: which individual engineers are actually driving results inside that delivery team, whether any of them are genuinely AI-native, and what happens to your roadmap when the engagement ends. That's not a knock on Serdao. It's just how managed delivery works. You buy an outcome, not a person. Which is fine, until you need to build something that requires a specific kind of engineer, the kind who reaches for AI not as a finishing tool but as the first tool, who can take an ambiguous problem and ship working code in a day instead of a sprint. Those engineers aren't on managed delivery benches. They aren't applying to marketplaces either. They're deep in someone else's codebase, shipping, heads down, not looking. Nextdev reaches the top 1% of AI engineers by going to find them, not by waiting for them to apply. Then we give them a real problem to build and watch how they work. Not a take-home quiz. Not a whiteboard. A genuine engineering problem, evaluated by people who can tell the difference between an engineer who uses AI fluently and one who just mentions it on their profile. When the right engineer is identified, we employ them for you. One named person, embedded in your team, working your hours, aligned to your roadmap. The contract, payroll, and compliance sit with us. You get the engineer. No twelve-month minimum. No mystery about who's actually doing the work. No offshore team you've never spoken to. You're not picking from who signed up. You're getting the engineer who never would have.

Serdao is a well-run business doing something genuinely useful for a specific kind of buyer. If you're a European company that needs managed web delivery and 24/7 IT support under a single, stable vendor relationship, eighteen years of 96% customer loyalty is a serious signal. That's not marketing fluff; that's clients renewing year after year because the model works for them. Where Serdao doesn't fit is the use case that's becoming more urgent in 2026: finding and embedding individual engineers who are already working at the frontier of AI-augmented development. The managed delivery model isn't built for that, and Serdao isn't trying to be. If your next hire needs to be someone who can multiply your team's output with Cursor, Claude, or whatever replaces them next quarter, you need a different kind of search.

The companies winning right now aren't buying more hours of managed delivery. They're finding fewer, better engineers and giving those engineers the tools and trust to move fast. That search is harder than it's ever been, because the best candidates are already employed, already shipping, and not watching their inbox. The teams that figure out how to find those engineers anyway are the ones building the next generation of products. The ones that don't are the ones wondering why their roadmap keeps slipping.
