Endole vs ListKit 2026: UK Company Data vs US B2B Leads

Endole vs ListKit is a choice between two different jobs. Endole tells you whether a UK company can pay you. ListKit tells you who to email today. Here is the short version.

TL;DR

• They are not really rivals. Endole is a UK company data and credit risk platform. It is built on Companies House filings. ListKit is a US-first contact database built for cold email and cold calling. Comparing them is like comparing a land registry to a phone book.
• Pick Endole if you sell to UK limited companies. It fits when your qualifying step leans on financials, directors, group structure, or credit risk.
• Pick ListKit if you run high-volume cold email or cold calling into US and global SMB. You get ready-to-send contacts with phone numbers attached.
• Neither one does on-demand email lookup well. Endole gives you companies, not verified work emails at scale. ListKit gives you lists, not a lookup API for the account you just found on LinkedIn.
• The common fix: keep one as your account source. Then bolt an email finder and an email verifier on top. Every account then turns into a contact you can actually reach.

What are Endole and ListKit, exactly?#

Endole is a UK business data platform. It is built on public filing data from Companies House: registrations, annual accounts, director appointments, charges, and group ownership. On top of that it adds credit scores, industry codes, and estimated financials for small filers. You get company profiles, a list-building tool, and credit reports. Buy them one at a time or by subscription. The buyers are UK credit teams, deal analysts, insolvency firms, and reps who need to know a target can pay before they pitch. See the product at endole.co.uk.

ListKit is a B2B contact database built for outbound agencies and small sales teams. The pitch is speed. Filter by title, industry, headcount, location, and tech stack. Then export contacts with verified work emails and, more and more, mobile and direct-dial numbers. It all flows straight into a cold email tool or a dialer. It sells credits, not research. Product details are at listkit.io.

So here is the honest framing of Endole vs ListKit. Endole answers "is this company real, solvent, and worth my time?" ListKit answers "who do I email tomorrow morning?" Some teams need both. Most teams think they need one and really need the other plus a lookup tool.

How do Endole and ListKit compare head-to-head?#

Endole vs ListKit pricing moves, and part of it sits behind a quote. So treat any number in a blog post — this one included — as a starting point, not a quote. As of early 2026, Endole's self-serve plans sit in the low tens of pounds per month for solo research use. API and bulk data access climb into enterprise pricing. ListKit's self-serve plans start around the $100/month band for a few thousand credits, with volume pricing above that. Check both vendor pages before you budget. Then check current reviews on G2 to see how those prices are landing with buyers this year.

What does each platform actually give you in a record?#

This is where the Endole vs ListKit comparison stops being abstract. Here is what lands in your spreadsheet.

What Endole hands you:

1. Endole company record — company number, registered address, SIC codes, incorporation date, filing history, current and past directors, shareholder and group structure, filed or estimated turnover, employee counts, county court judgments, charges and mortgages, and a suggested credit limit. Great for qualifying. Almost nothing you can put in the "To:" field.
2. Endole officer record — director name, month and year of birth, other roles held, and the address on file. Useful at small UK companies where the director is the buyer. Still no verified work email.

What ListKit hands you, and the gap both leave:

3. ListKit contact record — first name, last name, job title, seniority, LinkedIn URL, a work email marked verified, and often a mobile number. Add company name, domain, headcount band, industry, and location.
4. ListKit company attributes — technographics (what the company runs), rough revenue bands, funding signals, and location filters that let you slice a list without leaving the UI.
5. What neither gives you cleanly — the ability to say "here is a domain and a name I found five minutes ago on LinkedIn, get me the address now." Endole is not built for it. ListKit is built around pre-filtered lists, not one-off lookups. That gap is why teams add a domain search or a LinkedIn finder next to whichever platform they picked.

Which one is better for UK outbound?#

Endole, if your qualifying step is about money. ListKit, if it is about volume.

Selling to UK limited companies has a quirk you do not get in the US. The filings are public, standard, and free at source. That makes Endole's raw material genuinely different. Do you sell working capital finance, insurance, accountancy, insolvency support, or commercial property? Then a prospect's balance sheet decides the deal, and Endole's credit data does real work. You can build a list of UK companies with turnover between £2m and £10m, one SIC code, filings 30 days overdue, and a falling credit score. No US-first contact database can match that.

The catch: you end up with company names, addresses, and director names. You still need work emails. Endole's contact coverage below director level is thin. That is expected. It was never a people-data product. If your buyer is a Head of Finance and not the listed director, you are on your own.

ListKit's UK coverage exists, but it is not the core. You will find contacts at known UK mid-market firms and at tech companies with a busy LinkedIn presence. You will find fewer at a 40-person engineering firm in Sheffield with no marketing site. For UK SMB depth, the filings-first source wins on account discovery every time. That is the clearest split in the Endole vs ListKit debate.

Which one is better for US cold email and cold calling?#

ListKit, comfortably. Endole has almost no US company data to build outbound on.

ListKit fits how US outbound runs in 2026. Pull 2,000 filtered contacts. Drop them into a sequencer. Run a multi-channel cadence with a dialer chasing the mobiles. Measure by booked meetings. The phone layer is the part people renew for. Direct dials and mobiles are now the scarce piece, because inboxes are noisier and reply rates have fallen. If you call as well as email, that changes the ROI math against an email-only list vendor.

Two cautions apply to any list vendor, ListKit included:

• "Verified" is a point-in-time claim. A contact checked on the way into the database is not the same as a contact checked today, eight weeks later. B2B data decays fast. People leave, teams get restructured, and domains change. Re-verify before you send, not after your bounce rate tells you.
• Filter breadth is not filter accuracy. Headcount bands and revenue figures on SMB records are modelled, not filed. That is true across the whole category. It includes well-liked providers like BookYourData, which sells the same kind of pre-built list with its own promise on accuracy. Model the segment first. Then spot-check twenty records by hand before you trust the whole pull.

How accurate is the data, and how do you actually check?#

Vendor accuracy claims are marketing until you test them. Both Endole and ListKit publish confident numbers. So does every rival. Here is the test that costs you an afternoon and settles Endole vs ListKit for your own market.

That last row catches more teams than any other. Catch-all domains accept every address, so a naive checker marks them valid. You then learn the truth from your bounce report. Run exports through a catch-all verifier before they reach your sequencer, whoever supplied them.

What does each one cost you in practice?#

The number that matters is cost per deliverable contact, not cost per credit. A list that costs half as much and bounces at 9% is the pricier option. Bounces hurt your sender reputation, and that damage costs you the next three campaigns too. Run the maths on contacts you delivered and got replies from. If you want to compare a per-lookup model, Tomba pricing is public and not gated behind a quote. That makes the sum easier than it is with most list vendors.

When should you use neither — or both, plus something else?#

Three realistic setups.

You sell to UK SMB with a financial qualifying step. Use Endole to find and screen accounts. Then run each qualified domain through a bulk email finder to turn company records into named contacts with verified addresses. Endole tells you the company is worth chasing. The finder tells you who to email.

You run US-heavy volume outbound. Use ListKit as the main list source. Re-verify at send time. Then fill the gaps for accounts ListKit misses with on-demand domain search. No database covers every account you care about, and the fill-in layer stops you dropping named targets.

You are building a product or an internal data pipeline. Neither platform is really an API-first company. If your workflow is "our app needs an email for this domain and name, in 300ms," you want a lookup service, not a list marketplace. Wire the Tomba API or the data enrichment endpoint into your own system and skip the export-import loop.

What is the verdict on Endole vs ListKit?#

Endole wins on UK company data. ListKit wins on ready-to-send contacts. Neither wins on both, and no amount of feature-page reading changes that.

Choose by the question your pipeline is stuck on. Are deals dying because you pitched companies that could not pay? Buy financial data. Are they dying because you cannot reach enough of the right people? Buy contact data. Are they dying because your emails bounce? Then the problem is verification, and both vendors are the wrong purchase order.

Whichever source you land on, the last mile is the same. A name and a domain have to become a verified inbox address. That is what the Tomba Email Finder does. Search by domain, name, or company. Get a scored address with verification built in, on a free tier of 25 searches a month or $49/mo Starter with no quote call. Point it at your Endole export or your ListKit gaps and see how much of your list survives contact with reality.
