B2B contact database with live email verification at expo...

Speed

Lighthouse mobile performance 56/100 with an LCP of 31.9s — roughly 13x the 2.5s 'good' threshold. Desktop is better at 70/100. CLS is excellent (0.001) and TBT is acceptable (362ms), so the problem is load weight, not layout.

Argorant

About this app

Argorant is a B2B contact data platform built around a single, sharp promise: verified-at-export. Instead of selling you a static database and letting decay become your problem, it runs a live SMTP check against the recipient's mail server at the exact moment you download a list. Rows that fail are filtered out and cost you nothing — only deliverable contacts are charged. The database covers 626.5M contacts across 184 countries, with filtering by industry, country, size, role and technologies, plus free counting and masked previews before you spend a credit. What genuinely sets it apart is the agent-native layer: an MCP server, REST API and CLI let Claude, ChatGPT, Codex or your own agent search, count and export contacts under plan-level limits and credit accounting, which means an overnight agent can build a validated list without ever blowing your budget. There is no annual lock-in (monthly plans or a pay-as-you-go wallet that doesn't reset), no 'request a quote' wall, and self-s...

Scout Review

Written by AI from measured evidence, scored out of 100.

Argorant is a B2B contact data platform that bets on one promise: verified-at-export. Every email is checked live against the recipient's mail server at download time, and undeliverable rows cost nothing. The database claims 626.5M contacts across 184 countries with filtering by industry, country, size, role and technology, plus free counting and masked previews before you spend a credit. Pricing is transparent — $99/$249/$449 monthly tiers with credit-based billing, no annual lock-in, and a pay-as-you-go wallet that doesn't reset. The agent-native layer (MCP server, REST API, CLI) is the standout feature and genuinely rare in this category. Weaknesses: mobile performance is poor (Lighthouse 56, LCP 31.9s), security headers are largely absent (4/13), and accessibility has three real failures despite a 92 score. The product is early — domain registered 0.7 years ago — but the positioning against ZoomInfo, Apollo and Clay is specific and defensible.

Measure by measure

Usability

100 free credits and 300 campaign emails with no credit card is genuinely low-friction. Docs site is a real developer hub with API reference and MCP setup guides for Claude, ChatGPT, Codex and Cursor.

Design

Dark, modern SaaS landing page with animated workflow demos and clean three-tier pricing cards. Mixed German/English copy on the /de locale reads as localization in progress rather than finished polish.

Speed

Security

HTTPS enforced with SPF and DMARC in place, but no HSTS, CSP, frame protection, X-Content-Type-Options, Referrer-Policy, Permissions-Policy or secure cookies — 4/13 on the header checklist. No SOC 2, ISO or pen-test claims found.

Accessibility

Lighthouse accessibility 92/100, but three real failures: insufficient color contrast, undersized touch targets, and visible text labels without matching accessible names. No WCAG statement or a11y page found on the site.

Growth

Verified-at-export is a real, specific wedge against ZoomInfo's quote walls and Apollo's static decay problem. Agent-native MCP/REST/CLI access is a genuine differentiator. Domain is only 0.7 years old.

Improvement areas

Mobile performance: Lighthouse 56/100 with 31.9s LCP — needs payload reduction and lazy loading.
Security headers: 4/13 checklist points, no HSTS, CSP, frame protection or secure cookies.
Accessibility: three failing audits (contrast, touch targets, accessible names) despite a 92 score.

Design & Usability

Argorant's landing page is a competent dark-mode SaaS site with animated workflow demos showing the count-check-export-campaign loop, which is a smart way to explain a data product. The pricing page is clean and the credit model (1 credit = 1 validated contact, 0.5 for external verification) is stated plainly. The /de locale mixes German and English copy, which reads as localization still in flight. On usability, the free tier is genuinely generous — 100 credits, 300 campaign emails, no card — and the docs site is a real developer hub with an API reference, CLI guide, and MCP setup instructions for Claude, ChatGPT, Codex and Cursor. That's more than most contact-data tools bother to ship. The main friction is that the product is doing a lot at once (data, verification, campaigns, inbox, agent access), and the homepage tries to sell all of it in one scroll.

Speed & Security

Speed is the weakest measured dimension. Lighthouse mobile performance lands at 56/100 with an LCP of 31.9 seconds — that is not a rounding error, that is a page that takes half a minute to render its main content on a phone. Desktop is 70/100, so the issue is load weight on constrained connections, not a broken build. CLS is near-perfect at 0.001 and TBT is a reasonable 362ms, so the layout is stable and the JS isn't the bottleneck — it's the payload. Security is middling: HTTPS is enforced, SPF and DMARC are configured, but the header checklist comes back 4/13 with no HSTS, CSP, frame protection, X-Content-Type-Options, Referrer-Policy, Permissions-Policy or secure cookies. No SOC 2, ISO 27001 or pen-test claims appear anywhere on the fetched site. For a tool that handles API keys and connects to customers' Google Workspace and Microsoft 365 mailboxes, that's a gap worth closing.

Accessibility & Growth

Accessibility scores 92/100 on Lighthouse, which is strong, but the three failing audits are not cosmetic: insufficient color contrast, touch targets that are too small or too close together, and visible text labels that don't match their accessible names. The last one is the most concerning — it means some interactive elements announce the wrong thing to screen readers. No WCAG conformance statement or accessibility page was found. On growth, the idea holds up. The B2B contact data category is crowded with ZoomInfo (quote-based, annual contracts), Apollo (all-in-one but static data), and Clay (enrichment orchestration that still needs a source). Argorant's wedge is specific: verified-at-export with pay-per-valid pricing, plus agent-native access via MCP, REST and CLI. That last piece is the real differentiator — most contact tools have no safe programmatic path, and an overnight agent building a validated list without blowing the budget is a concrete, underserved use case. The domain is only 0.7 years old, so this is early, but the positioning is sharper than most newcomers in the space.

Conclusion

If you're an outbound team tired of paying for bounced emails and burning domain reputation, Argorant's verified-at-export model is worth a look — the free tier (100 credits, 300 campaign emails, no card) makes it cheap to test. If you're an AI-first operator or RevOps engineer who wants an agent to build and validate lists programmatically, the MCP/REST/CLI layer is the reason to pick this over Apollo. But go in with eyes open: the mobile site is slow, the security headers need work before you connect your Google Workspace, and the accessibility gaps mean some users will struggle with the interface. The idea is sharp; the execution needs another pass on the plumbing.

Suggestions for improvement

Fix the mobile LCP — 31.9s is a conversion killer. Compress hero media, lazy-load below-fold assets, and consider serving static HTML for the landing page.
Add HSTS, CSP, X-Content-Type-Options, Referrer-Policy and secure cookie flags. For a tool that connects to customer mailboxes, this is table stakes.
Publish a security page with SOC 2 roadmap or pen-test results. Enterprise buyers will ask, and 'we don't have one' loses deals.
Fix the three failing accessibility audits: color contrast, touch target sizing, and accessible names on labeled elements. Also add a WCAG conformance statement.

ZoomInfo

Enterprise-grade B2B data and go-to-market suite with huge coverage, but quote-based contracts, multi-module pricing and annual commitments that Argorant explicitly avoids.

Apollo.io

Popular all-in-one contact database plus sequencing platform; broader as an outreach tool, while Argorant narrows in on the verified-at-export data layer and agent access.

Clay

Powerful data enrichment and waterfall orchestration tool often paired with a source database rather than replacing one — a natural complement to Argorant via its built-in integration.
