6 Best B2B Databases for Singapore in 2026

A B2B database for Singapore is a searchable store of companies and their people. It needs enough depth in finance, technology and trade to build a real list. Sales teams, agencies, analysts and engineers who sell into the city-state need one. The market is small, so a thin database fails fast.

Of the five rivals, only ZoomInfo prints a Singapore figure, on a country map. The rest give a worldwide total and leave Singapore to the buyer. So we ran a real count on LeadOcean on 2026-10-21 and read every rival's published limits and list prices in September 2026.

Each tool below has its own page: Lusha, ZoomInfo, Apollo, ContactOut and Cognism. For the contact-focused ranking, see best B2B data providers for Singapore.

TL;DR

"1M records" means 1M work-email lookups that return a result, at list price. Where a vendor publishes no 1M price, we print none and do not multiply a rate out.

What we evaluated

• Singapore coverage: a figure for Singapore itself, with a source, or a free way to measure it.
• Free sizing: whether you can count a Singapore audience before you pay.
• Mailable depth: whether the number means people with a usable email or phone, or only profiles.
• API and MCP: whether a script or an agent can pull Singapore records directly, and at what rate.
• Price at volume: flat, credits, seats or quote, and the cost of 1M records.

We ran counts on LeadOcean only. We ran no query on the rivals, so we print no hit rates for them. Vendor figures are vendor claims, and each vendor counts a "contact" its own way.

1. LeadOcean: best for API and agent buyers

LeadOcean holds 693M people and 67M companies, and its country filter takes SG. We ran the test on 2026-10-21 with the free leadocean_count_leads and leadocean_count_companies MCP tools. Neither spends a record.

The result: 2,285,316 people in Singapore across all email statuses. 518,089 of them are mailable, meaning a verified, catch-all valid or catch-all email. They span about 48,987 employers. 35,769 mailable people are in the C-Team. On the company side, 92,870 companies have a Singapore headquarters, and 63,104 of them have 1 to 10 staff.

Small companies are the bulk of the company list, which helps a startup-focused search. The people list is the opposite for some roles, so count your own titles first. IT Services and IT Consulting (4,500 companies), Business Consulting and Services (4,107) and Financial Services (3,066) lead the industries.

curl -X POST "https://api.leadocean.io/v1/people/search?count=true&limit=1" \
  -H "x-api-key: $LEADOCEAN_API_KEY" \
  -H "content-type: application/json" \
  -d '{"country": ["SG"], "jobLevel": ["C-Team"]}'

Over REST, meta.total stops at 100,000, so use narrow filters or the MCP count_leads tool for exact totals. The company count is also free at GET /v1/companies/count. The MCP server at https://api.leadocean.io/mcp exposes 13 tools and signs in with OAuth 2.1. A single search pages to 10,000 rows, so split a big Singapore list by industry or headcount.

Pros

• Free, exact counts for people and for companies, with email status, title and size filters.
• Same data on every plan, including Free.
• A fair-use pace instead of credits: Agency is $497 a month with 200 requests a second.
• Hosted MCP server with 13 tools.

Cons

• No rep workspace, sequencer, dialer, CRM or Chrome extension.
• Free is 1,000 records, one-off, and bulk CSV export is not on Free.
• Phone and mailable counts depend on the filter, so read the label next to each number.

Best for: engineers, agencies and agents that build Singapore lists at volume and want a predictable bill.

Pricing: Free $0, 1,000 records for life. Solo $97 a month. Agency $497 a month. Platform $1,997 a month (LeadOcean pricing, October 2026).

2. Lusha: best for small batches with email and phone

Lusha prints no Singapore figure today. Its data page shows 515M+ contacts, 29M+ companies and 165M+ verified emails worldwide, with no country split (Lusha data page, October 2026). Test it on your own Singapore contacts with the 40 free credits.

An email costs 1 credit and a phone 5. Email plus phone is 7 credits through a single API request (Lusha API docs, September 2026). The MCP server has 50 tools and shares the REST credit pool (Lusha MCP docs, September 2026).

At volume the credit meter bites. 1M work emails by bulk API is 1,040,000 credits, and the largest public tier holds 10,000 credits a month. Scale is custom.

Pros

• Email, phone and company data in one lookup.
• An API key on every plan, Free included.
• MCP server with 50 tools.

Cons

• No public price at 1M.
• No Singapore figure on its data page.
• Rate limits are low on small plans: 40 a minute on Free and Starter.

Best for: small teams that look up Singapore contacts in batches of hundreds.

Pricing: Free $0 for 40 credits a month. Starter $49.90 a month ($37.45 billed yearly). Pro $69.90 ($52.45). Premium $399.90 ($299.95) (Lusha pricing, September 2026).

3. ZoomInfo: best for a published Singapore mobile count

ZoomInfo maps Singapore at 2.3M contacts, 601K mobile numbers and 139K companies (ZoomInfo data page, October 2026). Those are rounded vendor figures with no email split.

Its pay-as-you-go product, GTM AI, sells data credits from $20, at $0.45 a credit for 100 and $0.25 at 100,000. Search and lookup are free, and a record is charged once per 12 months (GTM AI pricing, September 2026; GTM AI docs, September 2026).

Because search is free, filter to Singapore first and spend credits only on rows you keep. API limits run from 5 requests a second on Builder to 35 on Scaling (GTM AI rate limits, September 2026). ZoomInfo has an official MCP server (GTM AI docs, September 2026).

Pros

• Published Singapore figures for contacts, mobiles and companies.
• Free search, with a record charged once a year.
• Official MCP server and a free tier with API access.

Cons

• Rounded figures, with no email split.
• The public slider stops at 100,000 credits, so 1M means Enterprise sales.
• Platform plan prices are not public: zoominfo.com/pricing showed a human check to our read.

Best for: teams that need Singapore mobile numbers and accept a sales call at volume.

Pricing: GTM AI pay as you go from $20, with 1,000 free data credits at signup (GTM AI pricing, September 2026). ZoomInfo platform plans are quote only in our read.

4. Apollo: best for a free count plus sequences

Apollo prints no Singapore figure that we could find. Its people search costs 0 credits, so you can measure Singapore yourself by location. An email costs 1 credit and a phone 8, and credits are pooled across the team (Apollo API pricing, September 2026).

The seat model is what hurts at volume. 1M work emails is 1,000,000 credits, which is 250 Professional seats at $99, or $24,750 a month at list on monthly billing. Billed yearly, Basic seats come to $19,600 a month equivalent (Apollo pricing, September 2026).

Paid enrichment endpoints allow 1,000 requests a minute, and search allows 200 a minute (Apollo rate limits, September 2026). The official MCP server works on any plan (Apollo MCP docs, September 2026).

Pros

• A free way to count Singapore people by location.
• Sequences, dialer and extensions in the same app.
• Official MCP server on every plan.

Cons

• Credits expire each billing cycle and do not roll over.
• A phone costs 8 credits.
• 1M emails means hundreds of seats.

Best for: reps who want a free Singapore count and a sequencer in one app.

Pricing: Free $0 (75 credits a month). Basic $65 per seat a month ($49 billed yearly). Professional $99 ($79). Organization $149 ($119) (Apollo pricing, September 2026).

5. ContactOut: best for cheap lookups outside the US

ContactOut prints no Singapore figure. Its own pages give conflicting global profile totals (ContactOut, September 2026). It sells a regional plan for contacts outside the US: Regional Email is $25 a month ($19 billed yearly) (ContactOut pricing, September 2026).

For a small team that looks up Singapore people one at a time, that is the cheapest paid plan on this page. It is not a bulk source. Self-serve fair use is 2,000 emails and 1,000 phones per account a month, with one user per company (ContactOut terms, September 2026).

API keys come from a sales meeting, with no public price (ContactOut API, September 2026). People Search allows 60 requests a minute. The MCP page shows 15 tools (ContactOut MCP, September 2026).

Pros

• Regional plans from $25 a month ($19 billed yearly).
• Profile-led lookups for people outside the US.
• MCP server with 15 tools.

Cons

• No Singapore figure.
• 2,000 emails per account a month, one user per company.
• No public API price.

Best for: recruiters and small sales teams that look up Singapore contacts one by one.

Pricing: Regional Email $25 a month ($19 billed yearly). Regional Email + Phone $49 ($39). Global Email $49 ($39). Global Email + Phone $99 ($79) (ContactOut pricing, September 2026).

6. Cognism: best for teams that take a quote and a sample

Cognism prints no Singapore figure and no price. Pricing is tailored by product, team setup and usage, with Standard and Pro plans by quote (Cognism pricing, September 2026). One credit is one revealed contact.

The API takes OAuth 2.0 client credentials and allows 500 requests a minute per operation (Cognism rate limits, September 2026). At 100 records a page, 1M records is 10,000 search calls. The MCP server has 15 tools that map one to one onto the API and use the same tokens and credits (Cognism MCP docs, September 2026).

Cognism's docs disagree on whether a count call costs a search token. The Credits page says yes, and the endpoint and MCP pages say no (Cognism credits docs, September 2026).

Pros

• A count endpoint and location filters with region and country.
• MCP server with 15 tools.
• Credits cover the platform, Enrich and the API.

Cons

• No public price and no Singapore figure.
• API and MCP need a package that includes them.
• Sizing a list may cost search tokens.

Best for: teams that will go through sales and judge Singapore coverage from a sample.

Pricing: No public price. Plans are Standard and Pro, quote only (Cognism pricing, September 2026).
