Syntellix is a LinkedIn marketing agency based in Ho Chi Minh City, Vietnam. We work with B2B companies that sell into Vietnam and Southeast Asia, and with teams that want senior LinkedIn execution without hiring and training someone in-house. In practice that means three jobs: finding and starting conversations with the right decision-makers, publishing founder content that makes those conversations easier, and setting up a company page that looks credible when a buyer checks you out. We don’t run ads, we don’t use automation tools, and we don’t promise numbers we can’t stand behind. This page explains who we work with, what we do and how a project runs.
Quick answer
Syntellix is a LinkedIn agency in Vietnam for B2B companies targeting Vietnamese and Southeast Asian buyers. We offer three services: LinkedIn lead generation, founder content and profile positioning, and company page setup. Every project has a dedicated Marketing Lead, our founder is involved in strategy, and the profiles, content system and CRM process stay yours when the contract ends.
Who we work with
Most of our clients fall into one of three groups:
- Foreign B2B companies selling into Vietnam. For example, a Singapore SaaS company selling to Vietnamese factories, or a European equipment maker looking for a local distributor. You know your product; you don’t yet know who signs off in a Vietnamese company or how they read a cold message.
- Vietnamese and regional B2B companies selling across Southeast Asia. Data, software, manufacturing and professional services firms that need to reach buyers in Singapore, Thailand, Indonesia and beyond.
- Founders and sales leaders who want senior hands on LinkedIn. You don’t want to hire a junior coordinator and spend six months training them. You want people who have done this before, every week.
We are not a good fit if you sell to consumers, if you mainly want LinkedIn Ads managed, or if you want thousands of automated messages sent each month. We do none of those.
Three services, one system
Each service stands on its own, and they build on each other. A company page and a positioned profile are the base; content makes strangers trust you; outreach turns that trust into conversations.
| Service | What it does | Best for |
|---|---|---|
| LinkedIn lead generation (Growth) | ICP definition, 100–200 researched lead profiles a month, 20–30 personalized connection requests a week, plus content and weekly reports | Teams that need conversations with decision-makers in Vietnam or Southeast Asia |
| Founder LinkedIn content (Authority and Foundation) | Profile positioning, a B2B content strategy for your industry and 8–12 posts a month written in your voice | Founders and executives whose name sells the company |
| Company page setup | A complete, keyword-ready company page in 1–2 working days, with a 7-day free warranty | New companies, new market entries and pages that were never finished |
Pricing depends on scope and markets, so we quote after a strategy call rather than publishing a rate card.
Why a Vietnam-based team
Plenty of agencies can schedule posts. Fewer know how a Vietnamese buyer actually decides. That local layer is where most foreign outreach goes wrong, and it is what we work with every day:
- Titles and language. Many Vietnamese decision-makers write their profiles in Vietnamese or in both languages. A search for “Purchasing Director” alone misses the “Giám đốc Mua hàng” and “Trưởng phòng Mua hàng” who hold the budget. We build searches in both.
- How decisions get made. In an owner-led SME, the owner often decides. In an FDI subsidiary, the local director may need sign-off from a regional office in Singapore, Japan or Korea. State-owned companies follow formal procurement. Each needs a different first message and a different contact.
- Where conversations continue. A LinkedIn chat with a Vietnamese buyer often moves to Zalo once there is trust. We plan for that handover instead of fighting it.
- Timing. The weeks around Tết are slow for new decisions. We plan campaigns around the lunar calendar, not only the Western one.
One current note: since October 2026, LinkedIn has been hard to reach on some Vietnamese internet providers. It is not nationwide and there has been no official statement. We factor it into timing and follow-up, and we’ll tell you honestly if it affects your target segment.

What we have done
We only publish results we can show. The main one:
- Easy Data, a Vietnamese data company, went from an unknown profile to 6,000+ connections with CEOs and Purchasing Managers in Southeast Asia, by combining LinkedIn with its website and CRM. The full Easy Data case study is in Vietnamese.
- We have helped connect 5+ B2B clients with buyers in Singapore, Thailand and Indonesia, and used the same system to find customers in Spain.
- We have built company pages for Easy Data, Test Mentor, HTN Solutions and Tam Phu WPF.
We won’t show you invented averages or anonymous “300% growth” claims. On the call, we’ll tell you what is realistic for your market and what isn’t.
How a project runs
- Audit and positioning. We review your profile, page and current results, then run a positioning interview with you. You need to be in that session; nobody can position you without you.
- Strategy plan. Who you target, what you say, which content and outreach each month.
- Execution and optimization. We write, research and send. You approve content before it goes out.
- Measurement. Weekly and monthly reports, then adjustments based on what the data shows.
Each project has a dedicated Marketing Lead, and our founder, Trang (Celine) Phan, is involved in strategy. Trang has 4 years in B2B marketing and has used LinkedIn for 6+ years. The published team also includes 2 Content Leads, 2 Business Development Specialists, a Content Marketing Specialist, a Graphic Designer, a Video Editor and a Technical Lead. Everything we build, from profiles to the content system and CRM process, belongs to you after the contract.
International clients work with us on Google Meet, in English, with updates sent asynchronously so time zones don’t slow the work. Details are on the contact page.
FAQ
Do you only work with companies in Vietnam?
No. Many clients are based outside Vietnam and want to reach buyers here or elsewhere in Southeast Asia. We also help Vietnamese companies sell regionally. What matters is that your buyers are on LinkedIn and that you sell B2B. If your target market is far outside our experience, we’ll say so on the call.
Do you run LinkedIn Ads?
No. Syntellix does not run paid ads and we don’t offer ads management. Our work is organic: positioning, content, research and personalized outreach. If you need ads alongside that, you’ll want a separate specialist, and we’re happy to coordinate so the messaging stays consistent across both.
Do you use automation tools for outreach?
No. Every connection request is written for a specific person after we read their profile. We keep volume deliberately low, 20–30 requests a week, because a restricted account costs you far more than slow growth. Automation is also against LinkedIn’s rules, and decision-makers notice templated messages quickly.
How much do your services cost?
We don’t publish prices because scope varies a lot: one founder or a sales team, one market or four, English only or bilingual. After a free 30-minute strategy call we send a proposal with a clear scope. Authority and Growth have a setup fee plus a monthly fee, with a three-month minimum.
Can you write in English and Vietnamese?
Yes. Our team is Vietnamese and works in English daily. For international audiences we write in English; when you sell into Vietnam, we can write outreach and some posts in Vietnamese or both, depending on who reads them. You approve everything before it is published or sent.
