Introduction
Finding the right B2B customers in Vietnam can be challenging for international businesses, particularly without local market knowledge or an established sales network. Identifying decision-makers, qualifying potential buyers, and maintaining consistent follow-ups all require time and resources.
Working with a B2B lead generation company can help businesses navigate these challenges. Providers such as Source of Asia (SOA) offer market intelligence and local sales development support, while others specialize in outsourced sales operations or appointment setting. Understanding these differences is essential when choosing a partner that fits specific business objectives.

What Are B2B Lead Generation Companies?
B2B lead generation companies help businesses find and connect with potential corporate customers. They identify target companies, research decision-makers, and initiate conversations that may lead to sales opportunities.
Some agencies specialize in outbound prospecting and appointment setting, while others also provide market research, partner search, and ongoing sales development.
Common B2B Lead Generation Services
Most B2B lead generation agencies offer services such as prospect research, outbound outreach, lead qualification, appointment setting, and sales follow-up.
Prospect research involves finding companies and decision-makers that match a client’s ideal customer profile (ICP). Agencies then contact potential buyers through email, LinkedIn, phone calls, or industry events.
Interested prospects are assessed based on their business needs, purchasing responsibilities, and potential fit before being introduced to the client’s sales team. Some agencies also manage CRM updates and pipeline reporting to help clients track opportunities and follow-up activities.
Why Local Expertise Matters for Lead Generation in Vietnam
For international businesses, finding potential customers in Vietnam can be challenging without an understanding of local industries, distribution networks, and purchasing structures.
In some sectors, purchasing decisions are made locally, while others involve regional headquarters or multiple departments. Identifying the right contacts requires research into how each target company operates.
A local lead generation partner can help businesses validate prospect information, communicate with Vietnamese decision-makers, and coordinate meetings. This support can be particularly useful for foreign companies that have not yet established a local sales team.

Greswin
Company overview and experience
Greswin is a Hanoi-based sales outsourcing company established in 2023. With approximately three years of operating history, it focuses on B2B prospecting, appointment setting, and account-based marketing.

Key services
According to Clutch, Greswin provides B2B lead generation, B2B appointment setting, sales outsourcing, social media marketing, and account-based marketing.
Sales outsourcing represents 65% of its reported service portfolio, with B2B lead generation and appointment setting each accounting for half of that category. Its listed services are therefore closely related to prospect identification and early-stage sales engagement.
Case studies and proven results
As of October 2026, Greswin has no published client reviews on Clutch. The available directory information also does not provide verified results from B2B lead generation projects, such as qualified meetings delivered or sales opportunities generated.
Although its services align directly with outbound B2B prospecting, businesses should request recent project examples, client references, and details of its qualification process before assessing its performance.

How to Compare and Choose the Right B2B Lead Generation Company in Vietnam
Compare B2B lead generation companies in Vietnam based on industry expertise, lead quality, proven results, and pricing.
Choosing a lead generation partner takes more than comparing company size or online ratings. A suitable agency should understand your industry, identify prospects with genuine commercial potential, and support a sales process that matches your business goals.
The five companies covered in this guide offer different services. The table below summarizes their main areas of expertise and the types of businesses they may be best suited to.
| Company | Main expertise | Best suited for |
| Source of Asia (SOA) | Market intelligence, B2B prospecting, partner search, and local sales development | International companies entering or expanding in Vietnam |
| TDCX | Sales outsourcing, customer acquisition, and customer engagement | Mid-sized and large companies requiring scalable outsourced sales operations |
| Swivelt | B2B lead generation, appointment setting, and CRM support | Technology and B2B companies seeking outsourced sales and CRM support |
| Greswin | Outbound B2B prospecting, appointment setting, and account-based marketing | Businesses seeking targeted prospecting and qualified sales meetings |
| Altius Link Vietnam | Lead generation, telemarketing, telesales, market research, and contact center services | Companies requiring telephone-based prospecting, market research, and outsourced customer outreach in Vietnam |
This comparison is based on publicly available company information and service descriptions. The suggested business fit reflects each provider’s service focus and does not represent an independent ranking of lead generation performance.
Industry Expertise, Services, and Local Market Knowledge
Start by looking at the industries an agency has worked with and the services it actually provides. Lead generation for a software company can be quite different from prospecting for an industrial manufacturer, particularly when it comes to identifying buyers, understanding technical requirements, and navigating purchasing decisions.
For example, an equipment supplier entering Vietnam may need a partner familiar with local manufacturers, procurement structures, and distributor networks. A technology company may prioritize LinkedIn outreach, CRM integration, and appointment setting.
Local experience is also worth considering. An agency with knowledge of Vietnam’s business environment can help identify relevant organizations, understand purchasing responsibilities, and manage communication with potential customers.
Before choosing a provider, check whether its industry experience and local resources match the type of business development support required.
Lead Quality, Qualification Process, and Target Clients
Generating a large contact list does not necessarily create valuable sales opportunities. What matters is whether those prospects match the business’s ideal customer profile (ICP) and have a realistic reason to consider its products or services.
A qualified prospect should meet relevant criteria such as industry, company size, geographic location, business needs, and purchasing responsibilities.
For example, an industrial automation supplier may need to identify manufacturers with specific production equipment, expansion plans, or investment requirements. A general list of factories would offer limited value without checking which companies meet those conditions.
When comparing lead generation agencies, examine how they identify prospects, verify contact information, and assess commercial interest. It is also useful to clarify the expected deliverables, since a contact list, a qualified lead, a confirmed meeting, and an active sales opportunity represent different stages of the sales process.
Agreeing on these definitions from the beginning helps businesses assess lead quality and measure performance consistently.
Client Reviews, Case Studies, and Proven Results
Client reviews and case studies offer insight into an agency’s previous work and ability to deliver. Platforms such as Clutch provide information about service specializations, customer feedback, and completed projects, but ratings alone do not determine which provider will generate better B2B opportunities.
Look for case studies involving similar industries, target markets, or business challenges. A useful case study should explain the client’s objectives, the work delivered, and the results achieved.
For lead generation projects, relevant results might include qualified prospects identified, meetings held with decision-makers, sales opportunities developed, or commercial partnerships established.
It is also important to distinguish between different types of results. Improvements in customer satisfaction, website traffic, or marketing performance may demonstrate an agency’s broader capabilities, but they do not automatically establish success in outbound B2B prospecting.
Where detailed case studies are unavailable, businesses should request recent project examples and client references before making a decision.
Pricing Models, Reporting, and Expected ROI
B2B lead generation agencies may charge monthly retainers, fixed project fees, or performance-based rates. Some also offer dedicated sales representatives through longer-term outsourcing arrangements.
Costs depend on the target industry, campaign duration, prospecting channels, required language capabilities, and level of sales involvement.
When comparing quotations, businesses should examine what each proposal includes. One provider may deliver researched contact lists, while another manages outreach, qualification, meeting coordination, and ongoing follow-ups.
Reporting is equally important. Before starting a project, agree on measurable indicators and how frequently results will be shared.
| KPI | What it measures |
| Qualified leads | Prospects meeting the agreed qualification criteria |
| Meetings booked | Sales appointments arranged with target companies |
| Meetings held | Meetings that actually take place |
| Lead-to-opportunity conversion | Percentage of qualified leads progressing into sales opportunities |
| Sales pipeline value | Potential commercial value of qualified opportunities |
| Customer acquisition cost | Total acquisition expenditure per new customer |
For businesses with longer B2B sales cycles, revenue may take time to materialize. Tracking lead quality, completed meetings, and opportunities progressing through the sales pipeline can provide a more useful view of early campaign performance.
A suitable agency should clearly explain its pricing, deliverables, reporting process, and how its activities contribute to the client’s sales objectives.

Its approach combines market research with direct commercial execution, making it relevant for companies that need to understand their target market before committing to a full local sales operation.
Market Intelligence and Qualified Prospect Identification
Effective B2B prospecting starts with identifying the companies most likely to become relevant customers, distributors, or business partners.

Frequently Asked Questions About Lead Generation Companies in Vietnam
Key questions about B2B lead generation in Vietnam, from operating without a local office to lead generation timelines and sales outsourcing.
Can Foreign Companies Generate B2B Leads in Vietnam Without a Local Office?
Yes. Foreign businesses can conduct market research, identify prospects, and engage potential customers in Vietnam without immediately establishing a local office.
Working with a local sales development or market expansion partner can support prospect qualification, business introductions, and commercial follow-up. This lets you test demand before committing to a larger investment. However, check any applicable requirements before undertaking regulated business activities, entering contracts, or conducting local transactions
How Long Does It Take to Generate Qualified B2B Leads?
The timeline varies by industry, customer profile, target market, and prospecting approach.
Initial activities usually include defining your ideal customer profile (ICP), researching target companies, preparing outreach materials, and identifying relevant decision-makers. The time needed to secure qualified meetings and create opportunities then depends on prospect responsiveness, purchasing requirements, and the length of the sales cycle. B2B sales cycles are often long, so judging results may take several months. Agree on realistic milestones and reporting expectations before launching a campaign.
What Is the Difference Between a Lead Generation Agency and a Sales Outsourcing Company?
A lead generation agency focuses on identifying potential customers, qualifying prospects, and creating opportunities for your sales team. A sales outsourcing company may manage a broader range of activities, including appointment setting, sales conversations, pipeline management, and customer acquisition.
Many providers combine both approaches. Compare the actual scope of responsibilities, especially who manages prospect qualification, follow-up, sales negotiations, and conversion.
