The SDR Team Lead

Weighted verdict

Runs eight SDRs against a monthly meeting target. Wants filters that find the right buyer at the right company, emails that do not bounce, and direct dials that reach a person. Measures a database by connect rate, not by the record count on the homepage.

Same scores as the panel view — this lens weights them the way this judge cares.

Scored by The SDR Team Lead

Coverage, accuracy & freshness

How this is scored

How much of the target market the database actually covers — judged on DACH and EU coverage as much as North American — and what the vendor documents about verification and refresh, because accuracy claims cannot be checked from outside.

0 — No stated coverage, no refresh cadence, no verification method; accuracy asserted as a percentage with nothing behind it.

3 — Headline record counts for the whole database, thin or unstated European coverage, and no description of how often records are re-verified.

5 — Coverage stated per country or region including DACH, email verification described, a stated refresh cadence, and firmographics beyond name and domain.

8 — Coverage broken down by country, industry and data type (email, direct dial, mobile), verification method and refresh cadence documented, company data drawn from official registers where available, and a bounce or credit-back guarantee with stated terms.

10 — The vendor is accountable for its data: per-country coverage and accuracy methodology published, every field carrying a last-verified date visible to the user, register-sourced company data, and credit-back terms that make inaccuracy the vendor's cost rather than the buyer's.

The SDR Team Lead

I found no public coverage figures — no record counts, no per-country or DACH numbers, no refresh cadence and no bounce or credit-back terms; the only accuracy practice described is filtering ISP, hosting, telecom, mobile and VPN IP ranges before matching. Enrichment fields like employee count, revenue estimate, industry and job title are listed, but with nothing on how often any of it is re-verified, so I cannot judge what connect rate this data would give my team. 1 4

Data sources & lawful basis

How this is scored

Where the personal data in the database comes from and on what legal basis it is processed — as evidenced on the vendor's own pages. Covers Art. 6(1)(f) legitimate interest, the Art. 14 notice to the people in the database, and whether they can find, object to and remove their record.

0 — No statement of where contact data comes from or on what legal basis; "GDPR-compliant" asserted without explanation, and no way for a listed person to object.

3 — Sources described in general terms ("public sources", "partners"), legitimate interest named without any balancing, and an opt-out request form as the only route for data subjects.

5 — Source categories named (registers, company websites, contributory networks, licensed partners), legitimate interest stated as the basis for EU records, a dedicated privacy notice for the people in the database, and a self-service opt-out or removal process.

8 — The above plus an Art. 14 notification practice described (people informed when added), contributory or browser-extension collection disclosed as such, a legitimate-interest assessment summarised publicly, and EU records handled differently from US records where the law differs.

10 — Provenance is traceable per record: the source and collection date available for each contact, Art. 14 notices sent and documented, the balancing test published, objections honoured across the whole dataset and suppressed permanently, and no data sourced by scraping behind logins or from contributors' address books without their contacts' knowledge.

The privacy policy covers Leadboxer's own website — cookies, server logs, tracking pixels, newsletter double opt-in, and data-subject rights to access, portability and erasure — and EU deployments are described as consent-gated before tracking starts. But for the people whose profiles get built I found no public information on where the enrichment contact details come from, the legal basis for holding them, an Article 14 notice, or a self-service removal route; personal details are stated to appear only when a visitor submits a form or replies by email. 2 4 5

Visitor identification & intent signals

How this is scored

Identifying companies behind website visits and surfacing buying intent — scored on what is identified (company or person), how the tracking works, and whether the vendor states that its script needs consent under §25 TDDDG and how it behaves without it.

0 — No visitor identification or intent data, or person-level identification of EU visitors with no statement of legal basis.

3 — Reverse-IP company identification with a cookie-setting script, no statement about consent, and match rates claimed without method.

5 — Company-level identification with filters, visit history per company, a stated position that the script requires consent where it sets cookies, and a consent-mode or cookieless option.

8 — Company-level only for EU traffic by design, cookieless operation documented, integration with common consent management platforms, intent topics or page-level signals with the source of third-party intent data named, and alerts routed to owners.

10 — Identification that survives a DPO review: no personal data of visitors stored, the TDDDG and GDPR position published and specific, third-party intent data sourced from a named co-op or panel with its consent basis stated, and scoring on intent that the user can trace back to the underlying visits.

Report an error

The SDR Team Lead

Company-level is the stated default, the IP address is used to identify the company but not written to disk, an IP-masking option zeroes IPv4 and IPv6 before storage, and EU traffic is documented to begin tracking, identification, enrichment and scoring only after valid consent through a consent-management platform. Scoring draws on page visits, form submissions and content interest categories, with alerts to email, Slack and CRM. What holds it back: the returning-visitor ID lives in a first-party cookie, no cookieless mode is documented, and I found no public statement naming the German TDDDG or the consent position for it. 3 4 5 7

Prospecting workflow & outreach rules

How this is scored

Search, list building and outreach — and whether the product helps the buyer stay within UWG §7 and the GDPR once the list exists, rather than leaving the legal risk entirely with the customer.

0 — A search box and an export button; nothing on the pages about what the buyer may lawfully do with the contacts.

3 — Filters on firmographics and job title, saved lists, and a terms clause making the customer solely responsible for compliance.

5 — Advanced filters including technographics and triggers, company-level lists and alerts, a global suppression or do-not-contact list, and guidance on cold outreach rules in the main EU markets.

8 — The above plus country-aware handling (for example flagging German contacts where cold calls and emails require consent), phone numbers checked against national do-not-call registers where they exist, and opt-outs from outreach synced back to the database.

10 — Compliance is part of the workflow: outreach channels restricted or flagged per country and contact type by default, suppression shared across the whole account and every export, the Art. 14 notice supported at first contact, and a documented record of how each contact entered the buyer's pipeline.

Report an error

The SDR Team Lead

Segments on industry, company size, location and behaviour, saved lead lists with scheduled export, and a visual pipeline with automated assignment by region, size, industry or product interest make the list-building half genuinely usable. The vendor states the customer is the controller and stays responsible for the communication and for removing data from its own systems in time; manual and API-driven deletion with downstream suppression controls exist, but I found no public information on cold-outreach guidance for the main EU markets, country-aware flagging of German contacts, or checks against national do-not-call registers. 3 4 5

CRM sync, enrichment & export

How this is scored

Getting the data into the systems where sales works — CRM sync, enrichment of existing records, API — and what happens to exported data, and to the buyer's access to it, when the subscription ends.

0 — Manual CSV export only; no CRM integration and no API.

3 — A one-way push to one CRM, CSV export, and no statement on whether exported data may be kept after cancellation.

5 — Native sync with the major CRMs including field mapping and deduplication, enrichment of existing CRM records, and a documented API with stated limits.

8 — Bidirectional sync with scheduled re-enrichment, update and deletion propagated when a record changes or a person objects, webhook or API access with credit costs per call published, and data retention rights after cancellation stated plainly.

10 — The vendor treats the buyer's CRM as the system of record: objections and corrections propagated into synced records automatically, full change history per field, a versioned API with a deprecation policy, and exit terms that say exactly which data the customer may keep and for how long.

Report an error

The SDR Team Lead

Two-way sync with Salesforce, HubSpot and Pipedrive, enrichment of existing contact records (the HubSpot integration enriches via tracking cookies), and a documented REST API returning JSON with a developer site covering the data model and guides. I found no public information on field mapping, deduplication, API rate limits or per-call costs, or on what a customer may keep after cancellation; the stated model puts removal from the customer's own systems on the customer, which reads as an instruction rather than exit terms. 4 5 6 7

European sovereignty

How this is scored

Where a database of EU residents' personal data is held, who the contracting entity and controller are, and which subprocessors see it. Independently sourced by the sovereignty pipeline; weighted heavily here, because the product itself is personal data about people who never chose the vendor.

0 — Non-EU vendor and contracting entity, hosting unstated, subprocessors unnamed, and EU residents' contact data processed outside the EU with no stated transfer basis.

3 — Non-EU contracting entity with an EU representative under Art. 27, or EU hosting offered while enrichment, support or AI processing stay non-EU.

5 — EU contracting entity and EU hosting as standard, but parts of the chain — data partners, enrichment sources, tracking infrastructure — are non-EU without an explained safeguard.

8 — EU contracting entity and controller, EU hosting on named infrastructure, subprocessor and data-partner list published, and any non-EU transfer named with its legal basis.

10 — Sovereign end to end and evidenced: vendor, controller, hosting, data partners and every subprocessor European, certification published, and a DPA covering both the customer's data and the database records the customer exports.

Report an error

The SDR Team Lead

The pages claim a GDPR-native architecture, 100% EU-based data hosting and EU-hosted ISO 27001-certified data centers, but those claims appear in a learn article, the privacy policy is silent on storage location, and no hosting provider, data partner or subprocessor list is named; the vendor's own site also integrates Facebook, Google and LinkedIn components. That is an EU-hosting promise without the named infrastructure or subprocessor disclosure I would need before putting EU visitor data in it. 2 5

Pricing transparency

How this is scored

Whether a buyer can compute the real annual cost from public pages alone — including credits per email, phone number and mobile, credit expiry, seat pricing, visitor-identification tiers and the API — in a category where the unit of billing is often invented by the vendor.

0 — No public prices at all; every tier is a sales conversation.

3 — A monthly headline exists, but what a credit buys, whether credits expire, or the cost of an additional seat is unstated — the invoice is unknowable.

5 — Tier prices public with credit allowances given, but at least one commonly needed piece (mobile numbers, extra seats, API access, CRM sync) is unpriced or behind a sales call.

8 — Every tier priced publicly with credits per data type, credit expiry and rollover, per-seat costs, overage rates, minimum term and VAT treatment stated.

10 — Complete price computability: the annual invoice derivable for a given number of seats, exported contacts by data type, identified companies and API calls, with every credit cost and the refund rule for inaccurate data published.

Report an error

The SDR Team Lead

Public entry points exist: a free tier with basic visitor tracking, IP-to-company matching and API access, a fourteen-day trial without credit card, a Signal Start plan at € 95 /month, and flat-rate plans with the captured pages giving different starting figures of $195 per month and $205/month, plus a custom enterprise plan. Pricing is described as usage-based with no published unit of usage, and I found no public information on seat costs, overage rates, expiry terms or VAT treatment — so the annual invoice for a fixed team size cannot be computed from the public pages. 1 4
