Endole vs Leadsforge 2026: UK Data or AI Lead Lists?

Endole vs Leadsforge is a comparison of two tools that barely overlap. Endole reads UK company filings. Leadsforge builds contact lists from a chat prompt. This guide covers what each one does well, what each one costs, and the gap both of them leave open.

TL;DR

• Endole is a UK company-intelligence platform built on Companies House filings — firmographics, financials, directors, credit signals. It is a research tool, not a prospecting list builder.
• Leadsforge is an AI list builder. You describe your ICP in plain English and it returns a contact list with emails. It is a prospecting tool, not a financial-data source.
• The two overlap far less than the "vs" framing suggests. If you are underwriting, qualifying, or territory-planning in the UK, Endole wins. If you need 500 contacts by Friday, Leadsforge wins.

Both tools also share one blind spot:

• Neither is primarily a verification engine. The deliverability of the email addresses they hand you is still your problem.
• Most teams end up running one of them plus a dedicated finder and verifier layer. That combination costs less than upgrading either platform to its enterprise tier.

What is Endole, and who actually uses it?#

Endole is a UK business intelligence platform. Its core asset is a structured, searchable layer over Companies House filings — the statutory register of every incorporated UK business — enriched with financial statements, director histories, group structures, industry codes, and credit-risk indicators.

What that means in practice: you can search for "manufacturing companies in the West Midlands with turnover between £2m and £10m, incorporated before 2015, showing year-on-year revenue growth" and get a defensible list of legal entities. Endole's typical users are credit teams, M&A analysts, procurement, and B2B marketers doing territory or TAM analysis in the UK.

What Endole is not built for is handing you firstname.lastname@company.co.uk for the person who signs off on your product. It will tell you a company exists, how healthy it is, and who its registered directors are. Directors are not always your buyers. In a 400-person business, the registered director is almost never the person you want to email.

What is Leadsforge, and how is it different?#

Leadsforge sits at the opposite end of the workflow. It is a conversational, AI-driven list builder: you describe your ideal customer profile in natural language ("heads of marketing at Series A SaaS companies in London, 20–200 employees"), and the system turns that into a query against its contact database. It returns a list with names, titles, companies, and email addresses.

The pitch is speed and zero learning curve. No filter trees, no boolean strings, no Sales Navigator gymnastics. For an SDR who needs a list this afternoon, that is genuinely valuable.

The trade-off is the one every AI-abstraction tool makes: you lose precision over the query. When a filter-based tool returns the wrong companies, you can see exactly which filter did it. When a natural-language layer returns the wrong companies, you rephrase and hope. The underlying data is a general-purpose contact database rather than a statutory register, so UK coverage on small and mid-market firms is not as deep as Endole's.

Endole vs Leadsforge: how do they compare head to head?#

Here is the honest side-by-side. Where a vendor does not publish a figure, this table says so rather than guessing — check both vendor pages before you buy, because tiers move.

The row that matters most is the third from the bottom. Neither Endole nor Leadsforge treats email verification as a first-class product. Endole does not claim to. Leadsforge bundles some validation, but bundled validation inside a list builder is structurally different from a standalone email verifier that runs SMTP handshakes, catch-all detection, and role-account filtering as its actual job.

Endole vs Leadsforge: which platform has better data?#

"Better data" means nothing until you name the axis. Break it into five.

1. Entity completeness (UK). Endole wins decisively. Every incorporated UK company is in the register by law. Leadsforge's database skews toward companies with a digital footprint, like every commercial contact database. That under-represents the 4-to-30-employee UK firms that make up most of the market.
2. Contact-level depth. Leadsforge wins. Endole gives you directors and registered addresses. Leadsforge gives you job titles, seniority, and mailboxes for people who appear on no filing at all.
3. Financial and risk signals. Endole wins with no contest. Filed accounts, gearing, CCJs, and credit ratings are not something an AI list builder produces.

The last two axes are where the picture gets murkier.

4. Freshness. Split decision. Endole is only as fresh as the filings, and for small companies accounts can be nine months stale by law. Leadsforge's contact data decays at the usual B2B rate. Roughly 25–30% of business emails go bad each year as people change jobs, a figure reported consistently across vendor benchmarks and G2 review data.
5. Deliverability of what you get. Both are weak here next to a purpose-built verification stack. This is the gap that quietly costs you domain reputation.

That fifth axis is where most evaluations go wrong. Teams compare record counts, buy the bigger number, then find that their bounce rate is 12% and their sending domain is throttled inside three weeks. Volume without verification is a liability, not an asset.

What does each one cost, realistically?#

Both vendors sit in the "talk to us" zone above the entry tier, which makes true cost comparison hard until you are in a sales cycle. Here is what to interrogate before signing.

• Endole: subscription tiers gate how many company reports and searches you can pull, with bulk data and API access sitting on higher plans. Ask specifically about report caps, whether exports are included or metered separately, and what the API rate limit is. Deep-data and bulk-feed access is quote-based.
• Leadsforge: credit-based. The critical question is what consumes a credit — is it a returned contact, a revealed email, or a query? And are credits refunded for hard bounces? Vendors that refund invalid records are quietly telling you they trust their data; vendors that do not are telling you something too.
• Tomba: published and flat. Free tier at 25 searches/month, Starter at $49/mo, Growth at $99/mo, Pro at $249/mo, Enterprise by quote. Full Tomba pricing is on one page with no seat minimums.

The pattern worth naming: when a platform hides pricing above the smallest tier, your effective cost is a function of your negotiating leverage, not your usage. That is fine for a 40-seat enterprise procurement team. It is punishing for a five-person sales org that just wants 2,000 verified contacts a month.

Which should you choose for UK outbound?#

Pick by the question you are actually trying to answer.

Choose Endole if:

• Your ICP is defined by financial characteristics — turnover band, growth rate, solvency, asset base.
• You sell into UK SMEs and need to confirm an entity is real, trading, and creditworthy before you invest sales time.
• You are doing TAM sizing, territory carving, or account-tiering for a UK go-to-market plan.
• You need an audit trail. "Companies House filing, FY2025" survives a compliance review. "The AI suggested it" does not.

Choose Leadsforge if:

• Your bottleneck is list-building speed, not list accuracy.
• Your team is junior and you want to skip filter training entirely.
• Your ICP is described more naturally in prose than in firmographic filters ("agencies that recently posted about hiring a paid-media lead").
• You are prospecting globally, not just in the UK.

Choose neither as your only tool if your primary output is cold email volume. That is the case where the missing verification layer becomes the whole problem, and where a dedicated email finder plus verifier does more for your reply rate than either platform's next pricing tier.

How do you actually stitch these together?#

The workflow that consistently outperforms single-vendor setups looks like this:

1. Define the account list in the tool that knows accounts. Endole for UK firmographic and financial precision, or Leadsforge's natural-language pass for a fast first draft.
2. Export domains, not contacts. Domains are stable. People move. A list of 800 domains ages far better than a list of 800 mailboxes.
3. Run domain search against those domains to pull the current, live contacts by department and seniority — including the people who joined last quarter and appear in no static database.
4. Verify everything before it touches a sequence. Catch-all domains, role accounts, and dead mailboxes get filtered here. This is the step that protects your sender reputation.
5. Enrich back into the CRM. Push firmographics from Endole and contact-level fields from your finder into the same record so scoring rules can see both. Data enrichment closes the loop.
6. Re-verify quarterly. With ~25–30% annual decay, a list you built in January is materially worse by June. Rebuild the contact layer, keep the account layer.

Step 2 is the one teams skip and the one that pays. Buying contacts locks you into a snapshot. Buying accounts and resolving contacts on demand means your data is generated the week you use it.

What are the common objections to this setup?#

"Two tools is more expensive than one." Usually not. The jump from a mid-tier plan to an enterprise plan on a data platform is typically larger than the entire cost of a finder subscription. A $49/mo Starter plan alongside your existing platform costs less than most enterprise upgrades, and it solves the specific problem those upgrades do not.

"Our platform already includes verification." Check the definition. Syntax validation and MX-record checks are cheap and near-useless on their own. What matters is SMTP-level verification with proper catch-all handling. Ask your vendor which of those they perform, and what they report on a catch-all domain. If the answer is "we mark it as valid," you have found your bounce source.

"We can just guess the pattern." Pattern-guessing works until it doesn't. Companies run mixed formats after acquisitions, use non-obvious aliases, and route to shared inboxes. A permutation guess that lands in a spam trap does more damage than a contact you never emailed.

"We need this in our own systems." Then API access is non-negotiable, and you should compare it early rather than late. A platform that gates its API behind a quote-only tier will shape your architecture around its pricing. The Tomba API is available on every paid tier, so you can script the enrich-and-verify step into an existing pipeline instead of running it as manual CSV work.

The verdict#

Endole vs Leadsforge is not really a head-to-head fight. They are complements that happen to show up in the same searches. Endole answers "is this company worth pursuing and can it pay?" Leadsforge answers "who do I contact and how fast can I get 500 of them?" Buying one and expecting the other's strengths is the most common mistake in this comparison.

What both leave on the table is the reliability of the email address itself. That is a narrow, technical problem, and it is best solved by a tool that does only that.

If your outbound depends on contacts that actually land, run your account list through Tomba Email Finder — find current work emails by domain, name, or company, verify them before they enter a sequence, and push clean records into your CRM. Start on the free tier at 25 searches a month, or move to Starter at $49/mo when you are ready to run volume. No quote call required.
