The best Apollo alternatives for Southeast Asia depend on what is missing for you. If you need deeper local company records, look at regional data providers such as The Grid or Asia-focused data such as Pubrio. If you need a large global platform with more enterprise depth, ZoomInfo or Cognism are the usual comparisons. If you mainly need emails and simple sequences, Hunter.io and Snov.io are lighter options. If you want company search, AI-drafted emails and follow-ups in one place for SEA markets, Saella (our product) is built for that.
No tool wins in every country, so test the same list of real SEA companies in each.
Key Takeaways
Apollo is a strong all-in-one platform. Most teams look for an alternative because results in their specific SEA market are thin, not because the product is weak.
Regional providers usually go deeper on local company records, such as Singapore registry fields. Global platforms usually go wider.
Contact data and outreach are separate jobs. Some tools below do only one of them well.
Check each tool country by country. Coverage in Singapore says little about coverage in Vietnam or Indonesia.
Test before you switch: 20 real target companies, the same list in every tool, scored on the same fields.
This post compares named tools. If you first want to understand the different types of prospecting tools and a buying checklist, read our guide to B2B prospecting tools for Southeast Asia.
Why look for an Apollo alternative for SEA?
Apollo is popular for good reasons. Its site describes a large global contact and company database, a workspace that combines prospecting, outreach and a dialer, and AI agents that can research, build lists, write outreach and follow up. There is a free sign-up with no credit card. For teams selling mostly into the US or Europe, it is very convenient.
The questions change when your buyers are in Ho Chi Minh City, Kuala Lumpur, Jakarta, Bangkok, Manila or Singapore:
Local company coverage. Many SEA buyers are small and mid-sized, family-owned or locally registered companies with a light LinkedIn presence. Global databases may return fewer of them.
Email coverage. A company record without a working email address cannot start a cold email campaign.
Local registry data. In some markets, official registry fields (registration number, industry code, incorporation date, entity status) are the most dependable way to confirm a company is real and active.
Language. Company names, addresses and industry labels may appear in local scripts or local terms. Search that only works well in English can miss records.
Follow-up. You still need a relevant first email, a healthy sending domain and polite follow-ups.
None of this means Apollo is a bad fit. It means you should test it in your market against tools that are built differently.
What is the quick comparison?
The Grid: SEA and ANZ company and people data, deepest in Singapore with registry-checked fields; includes outreach features. Best for Singapore, Malaysia and Thailand prospecting.
Pubrio: Company and contact data with a stated focus on Asia-Pacific, plus signals about companies entering new markets. Best for tracking expansion and Asia-wide research.
ZoomInfo: Large global GTM platform with data, intent signals and AI agents. Best for enterprise teams selling across many regions.
Cognism: Sales intelligence with phone-verified data and a strong European compliance focus. Best for teams whose core market is Europe, with SEA as a secondary target.
Hunter.io: Email finding and verification by company domain, plus simple sequences. Best for small teams that already know which companies they want.
Snov.io: Email finder, verifier, warm-up and email plus LinkedIn campaigns. Best for small teams that want data and outreach in one low-commitment tool.
Saella (our product): SEA company search by country and industry, AI-drafted emails you approve, and follow-ups. Best for small teams that want one workflow for SEA outreach.
The Grid: is it the best Apollo alternative for Singapore?
What it is. The Grid is a B2B sales platform focused on Southeast Asia and ANZ. Its site lists Singapore, Malaysia, Thailand, Australia and New Zealand, and describes itself as deepest in Singapore.
Strengths. For Singapore, The Grid says company records are cross-checked against ACRA, the national business registry, with fields such as UEN, SSIC industry codes, incorporation date, directors and entity status. It also lists decision-maker names and roles, validity-checked emails and direct dials, growth signals like hiring and leadership changes, plain-English AI search, CRM integrations (HubSpot, Salesforce, ActiveCampaign), and outreach from Gmail, Outlook or SMTP with AI-drafted first emails.
Limits for SEA outreach. Its listed markets do not include Vietnam, Indonesia or the Philippines, so teams selling there should check coverage directly before committing. Pricing was not listed with figures on the homepage.
Who it suits. Teams whose pipeline is mostly in Singapore or Malaysia and who value registry-backed company details.
Pubrio: is it a good choice for Asia-wide data?
What it is. Pubrio describes itself as market expansion intelligence for go-to-market teams. It tracks signals that a company is entering a new market, such as new offices, first local hires, localized ads and regional launches.
Strengths. Its site says its strongest coverage is Asia-Pacific and other under-served markets, naming Vietnam, Indonesia and Thailand among others. It mentions localized data sources, native-language search for several Asian languages, company and people search APIs, monitors that alert you to new expansion signals, and a sequences feature for multichannel outreach. There is a free tier and a free trial.
Limits for SEA outreach. The homepage does not describe email finding or verification, so check how many of your target companies come back with a sendable email. Its native-language search list did not include Vietnamese, Thai or Bahasa at the time of writing.
Who it suits. Teams that sell to companies expanding into or across Asia, or that want an Asia-heavy dataset to plug into their own tools.
ZoomInfo: is it worth it for SEA prospecting?
What it is. ZoomInfo positions itself as an all-in-one AI GTM platform for sales, marketing, RevOps and customer success teams.
Strengths. It combines contact and company data with firmographic, technographic and intent data, org charts, lead routing and CRM sync. Its site says records come from public web sources, regulatory filings, job postings and a contributor network, with human researchers verifying them. It offers AI agents for account research and meeting prep, API and MCP access, and integrations with Salesforce, HubSpot and Dynamics 365. Pricing is credit-based, and there is a free plan (ZoomInfo Lite).
Limits for SEA outreach. Like Apollo, it is a global platform, so depth in a single SEA country is something to test, not assume. It may be more platform than a small team selling into one or two SEA markets needs.
Who it suits. Larger sales and RevOps teams that sell across several regions and want data, intent and AI workflows in one enterprise system.
Cognism: does it work outside Europe?
What it is. Cognism is a sales intelligence provider offering contact search with buying signals, CRM enrichment, API and MCP access, and CRM integrations.
Strengths. Cognism highlights phone-verified data with extra verification layers, which matters for teams that call as well as email. It puts heavy weight on compliance, citing GDPR and CCPA alignment and Do-Not-Call coverage across Europe.
Limits for SEA outreach. Its site describes itself as built for growth in Europe and did not mention Southeast Asian coverage on the pages we read. Pricing is by quote through sales.
Who it suits. Teams whose main market is Europe and who also prospect into SEA. Test SEA results separately.
Hunter.io: is an email finder enough?
What it is. Hunter.io finds and verifies professional email addresses. You enter a company name or website and it returns addresses it has found for that domain.
Strengths. It is simple: domain search, an email finder for a named person, an email verifier, a free Chrome extension and automated cold email sequences. The free plan gave 50 credits a month, shared across finding and verifying emails, with no credit card when we checked.
Limits for SEA outreach. Hunter starts from a domain. It does not help you discover which Vietnamese logistics firms or Malaysian manufacturers to target, and many smaller SEA companies use free webmail or have thin websites, which limits domain-based finding.
Who it suits. Small teams that already have a target company list and need emails for it, or want to verify a list before sending.
Snov.io: is it a good all-in-one for small teams?
What it is. Snov.io is a sales tool that combines lead search, email finding and verification, email infrastructure, warm-up, multichannel campaigns and a light CRM.
Strengths. It covers a lot in one place: AI and filter-based lead search, LinkedIn lead search, an email verifier, help setting up SPF, DKIM and DMARC, automatic inbox warm-up, and sequences that mix email and LinkedIn steps. There is a free starting plan with no credit card.
Limits for SEA outreach. Lead discovery leans on web and LinkedIn data, so smaller local SEA companies with little online presence may be harder to find. Check results in each target country.
Who it suits. Small teams and freelancers who want one inexpensive tool for finding emails and running sequences, especially in markets where LinkedIn is widely used.
Saella: how does it compare for SEA outreach?
Disclosure: Saella is our product. We have tried to describe it as plainly as the others.
What it is. Saella is an outreach platform for Southeast Asia. You find companies by country and industry, focus on the ones that have an email on record, let AI draft a first email that you approve, and send follow-ups.
Strengths.
Company search by SEA country and industry, with industry codes normalized across countries so one filter works in each market.
An AI agent that reads your website or company documents and suggests companies that fit.
You can filter to companies that have an email on record, so you see the list you can actually reach before you write.
AI drafts the email and layout from your description; you edit it, and you approve every email before it goes out.
Automatic follow-ups go only to people who opened the earlier email, and sending pauses if bounces or complaints spike.
A free plan with no credit card.
Limits. Saella is company-first: it is built around company records rather than deep person-level data such as org charts or direct mobile numbers. It does not offer intent data or a dialer like the larger global platforms. If you sell mainly outside SEA, a global tool will fit better.
Who it suits. Small B2B teams selling into one or more SEA markets who want company search, email drafting and follow-ups in one workflow. Before sending at volume, read our guide to cold email deliverability.
How do you test an alternative before you switch?
Run one small, fair test instead of comparing feature pages:
Pick 20 real target companies across the SEA countries you sell into, including a few smaller local firms, not only well-known brands.
Run the same 20 through each shortlisted tool, including Apollo as your baseline.
Score the same fields: company found, correct industry and location, a sendable email, the right role or department, and how recent the record looks.
Send a small batch from your best two tools and compare bounces and replies, not just record counts.
Check the workflow cost: time from list to approved email.
If you need help defining which companies belong on that list, start with our guide to building a B2B database. For the first message itself, our B2B cold email templates give you a starting point.
Frequently asked questions
Is there a free Apollo alternative for Southeast Asia?
Several tools in this list had a free plan or free start when we checked, including Hunter.io, Snov.io, ZoomInfo (Lite), Pubrio and Saella. Free plans have limits, so use them to run your 20-company test rather than a full campaign.
Which Apollo alternative is best for Vietnam or Indonesia?
There is no single answer. Some regional providers focus on Singapore, Malaysia and Thailand, while others name Vietnam and Indonesia. Test with your own target companies in those countries and compare how many come back with a usable email.
Do I need a data tool and a separate outreach tool?
Not always. Hunter.io, Snov.io, The Grid and Saella all combine some data with sending. Larger teams often keep them separate.
Can I email every contact a tool gives me?
No. Having a record does not mean you may contact that person. Check the privacy and marketing rules in each country you target, send relevant messages, and make it easy for people to opt out.
