Kaspr vs Vainu in 2026: Contact Data or Company Signals?

Kaspr vs Vainu is the wrong fight. One tool sells contact data. The other sells company signals. This guide shows which gap you are filling, and what each one costs.

TL;DR

• Kaspr vs Vainu is not a real head-to-head. Kaspr sells person data: mobiles and emails, pulled next to LinkedIn profiles. Vainu sells company data: size, revenue, and buying signals, strongest in the Nordics.
• Pick Kaspr when the pain is "I can't reach this person." Pick Vainu when it is "I don't know which accounts to work."
• Kaspr charges per seat and per credit. Vainu charges a yearly data fee. The two cost curves split fast past five reps.
• Both carry GDPR risk. Kaspr handles personal data. Vainu mostly handles public company records, which is an easier sell to legal.
• Need verified work emails at scale, with no seats and no browser add-on? A dedicated email finder does that job for far less.

Most "Kaspr vs Vainu" searches start the same way. A colleague hands you a shortlist. You wonder why two tools with very different price tags sit on the same page. The short answer: someone mixed up contact data with account data. This post pulls them apart. Then it tells you which gap you are really filling.

What is Kaspr, and what does it do?#

Kaspr is a B2B contact-data tool built around a Chrome add-on. Open a LinkedIn profile, a Sales Navigator list, or a group. Click the add-on. Kaspr shows you phone numbers and email addresses. Cognism bought it in 2022. Kaspr now sits at the cheap, self-serve end of that lineup.

The source matters. Much of Kaspr's database comes from its own users. Install the add-on, and your contacts join the pool. That model covers European mobile numbers well. Direct dials in France, the UK, and DACH are strong. Coverage is thin wherever the user base is thin.

What Kaspr is good at:

1. Mobile numbers in Europe. This is why most teams buy it. Western Europe beats most US-built databases.
2. Work inside LinkedIn. Reps never leave the tab. Enrich, list, push to CRM, start a basic sequence.
3. Bulk pulls from Sales Navigator. Select a result set, pull contacts in one go, export.
4. A real free tier. A few credits each month, no card needed. Testing it costs nothing.
5. Native CRM push. HubSpot, Pipedrive, Salesforce, plus Zapier for the rest.

What Kaspr is not: an account-picking tool. It has no view on which companies you should call. It assumes the list already exists.

What is Vainu, and who is it for?#

Vainu is a company-data platform from Helsinki. It does not index people. It indexes firms — millions of them. Each record carries revenue, headcount, industry, registry data, tech in use, and site activity. It also carries trigger events.

A trigger is a change worth acting on. New funding. A new leader. An office opening. A public tender. A sudden hiring spree in engineering.

Vainu is strongest in the Nordics. Finland, Sweden, Norway, and Denmark keep very open business registers. Vainu built its moat by reading them properly, down to filed accounts you cannot get in most markets. Outside the Nordics and the Netherlands, coverage is real but thinner. Test that first in any trial.

The buyer is not a lone SDR. It is a revenue-ops or marketing-ops owner. They want to score, sort, and route accounts on autopilot. That is why Vainu builds inside Salesforce, HubSpot, Dynamics, and Pipedrive instead of shipping a browser add-on.

Kaspr vs Vainu: how do they compare head to head?#

Prices move. Treat the table as a guide and check both sites before you sign. Kaspr posts its tiers. Vainu does not. That alone tells you the deal is annual, run by sales, and open to talk.

Read the table again and the answer writes itself. These tools do not overlap on a single row that matters. If both landed on your shortlist, the real question was never "which one." It was "which layer of my data stack is broken?"

Which problem are you trying to solve?#

Run this check before you open either pricing page.

• "My reps have a list but cannot get anyone on the phone." That is a contact-data gap. Kaspr fits. Vainu will not help.
• "My reps call random firms and win rates are bad." That is an account-choice gap. Vainu fits, or an ICP score on the data you already own. Kaspr will just make you faster at the wrong thing.
• "My CRM rows have no industry, no headcount, no revenue." That is an enrichment gap. Vainu solves it well for Nordic data. A general data enrichment API solves it cheaper worldwide.

Two more, and they are the ones teams miss most:

• "I have 4,000 name-and-company rows and no emails." That is pure email discovery. Neither tool is built for it. You want a bulk email finder with a verify step.
• "I never know when an account is ready to buy." That is a signal gap. Only Vainu, or a dedicated intent vendor, covers it.

Most teams have two of these at once. Then they try to fix both with one purchase. That is how you pay enterprise money for a tool reps open twice a week.

Kaspr vs Vainu pricing at 5 and 20 reps#

Here is the part that surprises people. Kaspr looks cheap at one seat. It stops looking cheap around seat eight.

The Kaspr vs Vainu cost gap is not about the sticker price. It is about shape. Per-seat and per-credit pricing punishes success. The moment reps really use the tool, the bill moves. Data plans do the opposite. You pay the same whether reps log in or not. That is why Vainu rollouts die quietly when nobody drives adoption.

Want a third shape? Usage-based API pricing splits spend from headcount. Tomba pricing opens with a free tier at 25 searches a month. Starter is $49/mo, Growth $99/mo, Pro $249/mo. Credits are shared across the team, not locked to a seat. For an ops person running jobs nobody logs into, that gap is the whole budget.

Kaspr vs Vainu: data accuracy and GDPR risk#

Two separate questions. Teams mix them up all the time.

Accuracy. Much of Kaspr's data comes from its users, so freshness moves by region. European mobiles: strong. US direct dials: weaker than US-first vendors. Emails: decent, but each address is a guess until something checks it. Reviews on G2 praise the phone data and flag the email hit rate. That matches what most teams report after a trial.

Vainu's accuracy question is different. Register data is near-official in the Nordics, because the registers themselves are official. Triggers are noisier by nature. A flagged "expansion signal" may be a press release with no budget behind it. Judge triggers on precision, not volume.

GDPR. Kaspr handles personal data: names, work emails, and personal mobile numbers. None of those people opted in. Kaspr publishes its stance and honors deletion requests. But you run the outreach, so you carry the GDPR duty. A personal mobile number raises the bar far above a role-based work email.

Vainu's risk is lower. Company register data is not personal data. Where Vainu does show people, the same rules apply. But that is a small slice of the product.

One practical note. If you sell in the EU and legal is involved, expect a longer review for Kaspr than for Vainu. Plan for it.

Is there a better setup than picking one?#

For most mid-market teams, yes. It is also cheaper than either tool alone.

The stack that works splits three jobs that both vendors bundle:

1. Account choice — decide which firms to work. Vainu does this well in the Nordics. An ICP filter over your CRM does it well enough elsewhere.
2. Contact discovery — find the person and the work email. A domain search plus a name lookup solves this for a fraction of per-seat pricing.
3. Validation — confirm the address is live before it hits a sequence. An email verifier with catch-all handling guards the sender reputation you spent months building.

Split those jobs and no single vendor holds your pipeline. You pay top dollar only for the layer that truly needs it. For most teams that layer is account choice. Contact discovery was never worth €79 per seat per month.

One setup does favor bundling. A European outbound team of three to six reps who call more than they email. Kaspr's phone data plus the LinkedIn flow is hard to match cheaply. At that size the seat math has not turned on you yet.

Kaspr vs Vainu: which should you choose in 2026?#

Choose Kaspr if: you sell in Western Europe, phone is your main channel, reps work in Sales Navigator daily, you have fewer than eight seats, and you want to start today.

Choose Vainu if: you sell into the Nordics or Benelux, you own RevOps, your CRM is the source of truth, you need company data and triggers flowing on their own, and a yearly contract is fine.

Choose neither if: your real gap is verified work emails at volume. Same if your team sells in regions neither vendor covers, or you need API access instead of a browser add-on. That is an API job, and the Tomba API covers it with one build instead of two contracts.

Whatever you pick, run both trials on the same 100 target accounts. Not a demo list. Your list. Count usable records, not total records. Then divide by monthly cost. The winner is almost never the tool with the better deck.

---

Start with the layer that is actually broken. Kaspr vs Vainu is a question about layers, not vendors. If your reps have accounts but no way to reach the people inside them, that is a contact gap. It is also the cheapest one to fix.

Tomba Email Finder returns verified work emails from a name and a domain. Every result carries a confidence score and a source. Credits are shared across the team, and the free tier covers 25 real prospects. Find the emails first. Then decide if you still need the €79 seat.
