Pick each one when
Cognism
- The list leans European and phone data has to be screened against Do Not Call and TPS registers before anyone dials.
- An agent will call the data, and an MCP server at mcp.cognism.com/mcp saves the build.
- Your engineers need a documented API: OAuth 2.0 client credentials and 500 requests a minute per operation.
- Somebody outside your team will eventually ask where the contacts came from.
Lead411
- You want the price before the call: Ignite lists API access from $150 a month for 1,000 exports.
- Most lookups need both the email and the direct dial, and one export buys both.
- Your volume is lumpy, and exports that roll over to the next cycle suit it.
Neither vendor publishes a match rate you could hold them to, so the rate card only tells you half the story. Take 500 rows from the segment you actually sell into, run them through one trial and a small paid top-up on the other, verify both result sets, and divide spend by survivors. Half a day and about $20, and on a close pair it changes the answer often enough to be worth it.
What each one costs, tier by tier
Only one of these two publishes a rate card. Lead411 lists its tiers with prices, and Cognism quotes everything, so half of this comparison is a number you have to go and get. Every figure is read off the vendor's own pricing page, and the pages they came from are listed at the foot of this one.
| The short version | Cognism | Lead411 |
|---|---|---|
| Cheapest paid plan with the API | Not published | Ignite, $150 |
| Tiers published | None | 4 |
| Free tier | No free tier and no published price. Both plans include 5 seats. | 7-day free trial with 50 exports. No ongoing free tier, and the trial lists no API access. |
| Unit cost at entry | Not sold by the unit | $0.15 per export, at Ignite's starting price |
The cheapest paid plan is rarely the plan you end up on, because what moves you up a tier is usually volume rather than a feature, and the two cards below say what each side publishes and what it keeps off the page.
Cognism
Cognism publishes no price at all, so there is no rate card to put here. Everything is quoted, which means the number you get depends on what you ask for and on where in their quarter you ask it.
Get these in writing before you sign: the per-unit rate at your volume, the annual minimum, how many seats that price assumes, whether API access is included or an add-on. Without the first two you cannot compare this against anything else on this page.
Lead411
Lead411 publishes 4 tiers, one of them a free trial, and the paid ladder runs from $49 to $150, with a quoted tier above it.
Free trial
- Verified emails and direct dials
- Chrome extension
- No API access listed
Spark
- $490 a year billed annually, for 12,000 exports and buyer intent
- $0.049 an export at the monthly rate
- CRM customizations and the Chrome extension, no API
Ignite
- The cheapest plan that lists API access
- $0.15 an export at the published starting price
- $1,500 a year billed annually, flexible exports, intent as an add-on
- Multiple users with admin control
Blaze
- Unlimited exports a year
- API access, custom onboarding, optional buyer intent
What Cognism and Lead411 cost at your volume
Put your own volume in. The model picks the cheapest published plan that covers it on each side, which is the question a rate card cannot answer and the one that decides the bill.
Cognism
Publishes no price, so there is nothing here to model and the lines below say what to ask for.
Lead411
Priced on the volume you use, so the plan that covers a normal month is the one that decides the bill.
Plans are read from each vendor's own pricing page and the model picks the cheapest one that covers you, so these are list prices on the billing term each vendor publishes, annual where that is how it prices, before any discount you negotiate. Cognism publishes no price, so nothing is modeled there and the panel says what to ask for instead.
What a year costs at three volumes
The same plan-fit arithmetic as the model above, run out to a year, because an annual number is what a budget actually asks for.
The priced columns move with volume, through a bigger plan or more seats.
| A year at | Cognism | Lead411 |
|---|---|---|
| 1,000 a month | Quoted | $1,800 Ignite |
| 10,000 a month | Quoted | Quoted |
| 50,000 a month | Quoted | Quoted |
Cognism does not publish enough to price a year, so that column is marked rather than filled. These are list prices on the published plan that covers each volume, on the billing term each vendor publishes, so they are the number before you negotiate.
How this plays out once it is running
The Cognism vs Lead411 choice is between two kinds of opacity. Cognism publishes no price at any tier: two plans, five seats each, both quoted. What it does publish is the API, in full, from OAuth 2.0 client credentials in M2M Connect to a 500 requests a minute ceiling per operation with separate windows.
Lead411 is the mirror image. Its pricing page prints Spark at $49 a month for 1,000 exports and Ignite from $150 a month with API access, plus $490 and $1,500 a year on annual billing. Nowhere on its site is there an API reference, an authentication scheme or a rate limit; the homepage link labeled Lead Enrichment API goes to the pricing page.
So the evaluation work lands in different places. On Cognism you can build a proof of concept against the docs and then wait for a number. On Lead411 you can budget from a published starting price, $150 a month for Ignite, though its FAQ says Ignite is quoted by team size and features, and then wait for the integration details. Until you have them, the developer-friendly API its homepage describes is a claim rather than something you can test.
What each one is genuinely good at
These are the things that keep somebody paying after the first month, which is a different question from what the marketing page leads with.
Cognism
The compliance posture is the product
Cognism notifies the business contacts it holds within GDPR timeframes and screens its phone data against 15 Do Not Call and TPS registers. It carries ISO 27001, ISO 27701 and SOC 2 Type II. Lead411 is a registered data broker with a CCPA page in its footer, which is a disclosure rather than a screening process.
A documented API and an MCP server
Cognism publishes its authentication, its request limits and its metering, and runs an MCP endpoint at mcp.cognism.com/mcp beside the REST API. An engineer can read how the integration will work before anybody signs, and an agent can connect with a configuration line. On Lead411 neither is possible from public material.
A throughput ceiling you can plan against
Five hundred requests a minute per operation, each with its own window, is a number you can size a backfill against. Lead411 publishes no request rate at all; its FAQ says there are no data caps or daily limits, which describes exports rather than how fast the API will answer.
Lead411
One export is the whole contact
A Lead411 export unlocks a contact with its verified email and its direct dial together, and the pricing page lists direct phone numbers on every plan. At Ignite's published starting price that is $0.15 a contact, both fields included. Cognism meters search tokens for the rows a query returns and credits for the contacts you reveal, and prices neither.
A published starting price
Spark is $49 a month for 1,000 exports, or $490 a year for 12,000 with buyer intent added. Ignite starts at $150 a month and $1,500 a year, and it is the plan that lists API access. Lead411 also says it will match or beat most enterprise competitor quotes, which gives you a lever against any quote you already hold. Ignite's $150 is a starting price: Lead411's FAQ says the plan is quoted by team size and features.
Exports roll over, and there is a real trial
Unused exports roll over to the next billing cycle on every subscription, so a quiet month is not a lost one. The free trial is 7 days and 50 exports, enough to check whether your kind of company comes back with a direct dial before you commit. Cognism has no free tier and no published trial.
Where each one falls down
Every provider on this site has a case it handles badly, and the people who find out are the ones who bought it for that case. These are the ones worth knowing before you sign rather than after.
Cognism
No published price, and five seats in the floor
Both Cognism plans include five seats whether or not five people will use them, and neither carries a number. A headless pipeline is buying a team license to get an API key, and the cost of finding out what that license costs is a sales process.
Three meters, and the binding one is not the obvious one
Search tokens meter rows returned, credits meter contacts revealed, and requests are capped per operation. Teams size against credits because the contract talks about credits, then hit the token ceiling on a broad search that returned far more rows than it revealed.
Lead411
No public API reference
Lead411 publishes no endpoints, no authentication method and no rate limits. The homepage calls it a developer-friendly API and links to the pricing page, and the only way to learn what a request looks like is to ask. For an integration you are going to maintain, that is the first question to settle, not the last.
The cheap plan has no API, and unlimited means Blaze
Spark at $49 lists no API access, so the programmatic floor is Ignite from $150. The FAQ says Lead411 has no data caps, but Spark and Ignite both list monthly exports; unlimited exports belong to Blaze, which is annual and quoted. Buyer intent is on annual plans only, and an add-on on annual Ignite.
No MCP server
There is no MCP endpoint, so an agent integration means building against an API whose reference you have to request first. Cognism, Lusha, Apollo and RocketReach all run one in this directory.
Using Cognism and Lead411 together
Teams comparing these two often end up running both, and the arrangement below is the one they settle on.
Running both is a regional arrangement rather than a redundant one. Lead411 on the North American rows where a $0.15 export buys the email and the direct dial together, Cognism on the European rows where its database and its register screening are the reason to pay for it. The routing rule is the country on the account record, decided before the call goes out.
The practical constraint is Lead411's integration. Until you have its API terms, the reliable route in is one of the 25 or more CRM integrations it lists, so the split may be Cognism through its API and Lead411 through a CRM sync. That is a fine arrangement for a sales team and a weak one for a product, where you want both sides behind code you control.
The exception is compliance, and it does not route. If Cognism is on this page because somebody needs to answer where the contacts came from and whether the numbers were screened, the North American rows need that answer too. Decide whether the posture is a requirement or a preference before you design the split, because it changes the answer from both to one.
Cognism or Lead411, for you
Five questions, answered from the same records as the rest of this page. Nothing is sent anywhere and there is no result to email yourself.
Each answer leans one way. The recommendation appears here once you have picked at least two.
A tool like this can only weigh what is on the page. It does not know your workload, and the one test that does is the bake-off on this page: your own rows, queries or records, run on the cheapest entry each side offers.
Where an answer leans on a certification or an integration, it means that vendor publishes it on the pages this directory read, which is not the same as the other one lacking it. The sources are listed at the foot of the page.
Where the data comes from, and what you may do with it
The question that arrives late and expensively is who is allowed to hold the data. These are the fields each one returns, the coverage it claims and the compliance it publishes.
| Provider | Fields returned | Coverage | Compliance | Redistribution |
|---|---|---|---|---|
| Cognism | Work email, Mobile phone, Firmographics, Technographics, Intent and news, Job postings, Job changes | Global | ISO 27001 ISO 27701 SOC 2 Type II GDPR notified data | Not stated |
| Lead411 | Work email, Mobile phone, Firmographics, Technographics, Intent and news, Job postings | Global | CCPA | Not stated |
None of these states a redistribution position on its pricing or docs pages. Internally that never matters. Put the rows in something your customers can see and it becomes the question your legal team asks first.
Two practical notes that apply to every provider on this page. A compliance badge describes the vendor rather than your use of it, so a GDPR DPA does not give you a lawful basis for the outreach you send. And every one of these vendors runs its own opt-out, which means a person who asks you to delete their record has to be removed from your copy as well as from theirs.
Moving between Cognism and Lead411
Most readers of this page are already on one of these two, and the order below catches the expensive mistakes while they are still free.
Measure the thing you are about to lose
Run 500 rows you already have through Cognism and record the match rate, the fields that came back populated and the cost. Without that number a migration cannot be judged, because every provider looks cheaper per unit than the one you are paying for today.
Check which fields change
Lead411 does not return job changes, which Cognism does. If anything downstream reads that field, the switch changes your pipeline as well as your vendor.
Rewrite the auth and the limits, in that order
Cognism authenticates with OAuth 2.0 client credentials, from M2M Connect in platform settings. Lead411 publishes no authentication method. Lead411 has no public API reference; access is set up with Lead411 on the Ignite or Blaze plan.
The limits are the part that bites later. Cognism's limits: 500 req/min per operation, separate windows. Plus search tokens and credits.
Lead411's limits: not published. Lead411 says there are no data caps or daily limits, which describes exports rather than request rates. A loop tuned to the first will either crawl or get throttled on the second.
Run both for one billing cycle
Keep the old key live and route a slice of real traffic to the new one. A month is the shortest honest test, because credit expiry, rollover and the overage rate only show up at renewal and those are where the surprises live.
Cancel on the renewal date
Credits on most of these plans do not survive a downgrade. Check what happens to the balance you have already paid for, and time the switch so you are not buying the same records twice.
The step people skip is the first one, and it is the only one that cannot be done after the fact. Once the old key is off you have nothing to compare the new match rate against, so a provider that is quietly worse on your segment looks like a provider that is fine.
What practitioners say about Cognism
The one part of this page that is not a vendor claim. Quotes are transcribed as written, linked to the thread, and nothing here is the only source for a figure in the tables above.
The regional split is the real difference, and practitioners buy both
Each data tool only really excels at one or two things. ZI is solid for NA mid-market and enterprise, while Cognism crushes it in EMEA and cell numbers. Every time I need one, we run a trial. If you've got the budget, use 2-3 tools to cover more ground. Right now, I'm using Clay for data infrastructure, Cognism for EMEA, and ZoomInfo for the US. sometimes Cognism finds data that ZI can't-and vice versa.
r/SalesOperations · November 2024 · 5 points
The comparison pages here reach the same place from the rate cards rather than from experience: Cognism sells notified EMEA data and mobile coverage, ZoomInfo sells North American breadth, and neither of them publishes a price. This is somebody running both with Clay in front, which is the arrangement those verdicts describe rather than the either-or the question usually assumes.
Coverage is the one thing nobody in this category will put a number behind, so "crushes it in EMEA" is an experienced opinion and not a measurement. The thread it sits in is itself a request for accuracy benchmarks that do not exist, which is a fair summary of the evidence available on either vendor.
14 threads read on 13 October 2026, searched by vendor name. Scores and dates are the comment's own. Nothing here is the only source for a price or a limit on this site: every figure in the tables above comes from a vendor's own page.
The wider field for both
Sometimes the answer is neither, and the reason you are comparing these two points somewhere else entirely: Cognism alternatives and Lead411 alternatives both start from the reason people leave.

Cognism and Lead411, answered
Read from the same records that drive the table above.
Is Cognism or Lead411 cheaper?
Cognism does not publish a price for the API, so the two cannot be compared on cost. Lead411 starts at $150 a month on Ignite, which is as far as the comparison goes.
Can I try Cognism and Lead411 for free?
Cognism: No free tier and no published price. Both plans include 5 seats. Lead411: 7-day free trial with 50 exports. No ongoing free tier, and the trial lists no API access.
What are the rate limits on Cognism and Lead411?
Cognism: 500 req/min per operation, separate windows. Plus search tokens and credits. Lead411: Not published. Lead411 says there are no data caps or daily limits, which describes exports rather than request rates.
Do Cognism and Lead411 both have MCP servers?
One of them. Cognism ships one at https://mcp.cognism.com/mcp; Lead411 documents none.
Which is better, Cognism or Lead411?
Pick Lead411 if you want a published price and one unit that buys the email and the direct dial together, and get its API terms in writing first, because it publishes no API reference. Pick Cognism if the list leans European, if an agent needs an MCP server, or if somebody will ask how the contacts were sourced and screened.
What are the downsides of Cognism and Lead411?
Cognism: no published price, and five seats in the floor; three meters, and the binding one is not the obvious one. Lead411: no public API reference; the cheap plan has no API, and unlimited means Blaze; no MCP server. The Limits section above has each one in full.
Can you use Cognism and Lead411 together?
Running both is a regional arrangement rather than a redundant one. Lead411 on the North American rows where a $0.15 export buys the email and the direct dial together, Cognism on the European rows where its database and its register screening are the reason to pay for it.
Can I migrate from Cognism to Lead411 without losing data?
Not without losing a field. Lead411 does not return job changes, which Cognism does, so anything downstream that reads it has to change. Either way, measure your match rate on 500 rows before you switch, because that number is the one you cannot recover afterwards.
