A side-by-side look at how the two compare, and which one fits your use case.
| Dimension | PersistData | Lead411 |
|---|---|---|
| Data model | Server-side data API; per-request fetch, not a large owned brand-name database | Owned proprietary B2B database, not a live LinkedIn scraper and not a bring-your-own-cookie tool. Lead411 markets technology aggregation plus human validation, with what it calls 'triple-verified' emails (SMTP + human + ESP-open per the vendor) and 'double-checked' direct dials; the Chrome extension serves Lead411's own DB while you browse LinkedIn rather than scraping the page (lead411 extension page, syncgtm 2026). Vendor-claimed size (not independently audited, as of June 2026): ~450M contacts and 20M-30M companies, with the company count inconsistent across the vendor's own materials (syncgtm '450M across 20M companies'; older Gartner-era marketing '30M companies'). PersistData is also an owned/server-side dataset, so the 'real database, not your cookie' property is shared, not exclusive; Lead411's claimed scale is far larger but is a vendor claim. |
| Login / seat required | No login, no seat, no extension | Yes to all three for normal use. Lead411 is a seat-based SaaS: you log into web.lead411.com on a paid per-user subscription, and the Chrome extension is the headline workflow for finding emails/phones on LinkedIn and company sites; an API exists only on Ignite and above. The extension page does not spell out a precise 'subscription required for full functionality' line, so treat the paid-seat dependency as practical positioning rather than a verbatim quote (lead411.com, 2026). This is the opposite of PersistData's server-side, no-login/no-seat/no-extension positioning, a genuine structural difference in the default workflow. |
| LinkedIn account ban risk | None; fully server-side, never touches your LinkedIn session | Low-to-moderate for your LinkedIn account: materially lower than bring-your-own-cookie scrapers, but not strictly zero. Per Lead411's extension page and syncgtm (2026), the extension serves Lead411's own database rather than scraping LinkedIn in real time, so it should not run high-volume profile fetches under your logged-in session (the main documented driver of restrictions). Residual risk: it is still a browser add-on active on LinkedIn pages, and LinkedIn's User Agreement broadly prohibits plugins that copy profile data; LinkedIn enforced aggressively in 2025 (Apollo and Seamless company pages removed March 2025; its suit drove Proxycurl to shut down July 4, 2025). Lead411 publishes no 'no ban risk' guarantee and we assert none on its behalf. For fairness, lower account-ban exposure is NOT exclusive to PersistData; any own-database/server-side provider (including Lead411's own Ignite+ API) shares it. |
| Pricing model | One-time packs or month-to-month; transparent per-credit (PersistData's published terms) | Credit/export-based seat SaaS with multi-year discounts. Per Lead411's own pricing page (verified June 2026): Pilot Light = free 7-day trial (50 exports); Spark = $49/mo for 1,000 exports/mo, or $490/yr for 12,000 exports/yr (annual adds buyer intent); Ignite = from $150/mo (from $1,500/yr), adds API; Blaze = custom quote, marketed as 'unlimited exports/year' with API + premium; multi-year discounts commonly cited ~10-20% for 2-3 year terms. Conflict to flag: 2026 third-party trackers (Capterra, GetApp, derrick-app, prospeo, saleshive) still cite older figures (Spark ~$75/seat/mo annual or ~$99 month-to-month, ~200 exports/mo, a reported ~3-month minimum, Ignite ~$3,000/yr, Blaze ~$6,000+/yr, Bombora intent ~$750/seat/yr add-on), likely a 2026 Spark price cut trackers haven't updated; treat lead411.com as current authority and confirm caps/minimums at quote time. PersistData markets ~$0.02-$0.10/credit on packs or month-to-month, undercutting Lead411 on raw price for pure data pulls; Lead411 bundles a fuller platform plus intent for the spend. |
| Approx. $ per record | ~$0.02-$0.10 per credit; 1 credit per profile/company, 5 credits per verified email (PersistData's stated rates) | Approximately $0.04-$0.05 per exported contact at plan allocation, derived from list prices (not a Lead411-published per-record rate). syncgtm.com (2026) computes ~$0.049/contact on monthly Spark and ~$0.041/contact on annual Spark ($490/yr / 12,000 exports). Overage rates are third-party-reported (derrick-app/prospeo 2026), not on the official page: Spark ~$0.50, Ignite ~$0.44, Blaze ~$0.40 per export. One export bundles email + direct dial together (Lead411 does not appear to meter them separately), so the effective cost per usable record can be better than competitors that meter phone separately. PersistData markets ~$0.02-$0.10/credit (5 credits per verified email), so on a verified-email basis the two land in a similar ballpark. |
| Pay only for found | Yes; a not-found costs 0 credits (per PersistData's terms) | Partially, and unconfirmed: we do not claim a no-charge-on-miss guarantee for Lead411. Per bookyourdata (2026) and Lead411 materials, viewing profiles, emails and phones in the app is described as unlimited/free, and a credit is consumed when you export or push a record to a CRM/integration (one credit = one contact export, email + dial bundled). What is NOT confirmed by any credible public source is whether an export returning no usable data costs zero, i.e. a true 'miss = 0 credits.' Because billing is on export of a record it behaves closer to pay-for-the-record than pay-per-search-attempt (you do not burn credits just searching), but there is no published Lead411 statement that a failed or empty enrichment is free. PersistData's explicit 'a miss = 0 credits' is a cleaner, stated guarantee; Lead411's no-charge-on-miss behavior is undocumented. For fairness, pay-for-found is offered by some other vendors too, so it is not unique to PersistData. |
| Free tier | Evaluation via low-cost packs (no perpetual free plan) | A 7-day free trial ('Pilot Light') with 50 export credits, no credit card required (lead411.com/pricing and softwareadvice, 2026). Per those sources the trial includes verified emails, direct dials, advanced search, company/employee data, and the Chrome extension. It is a time-boxed trial sized to evaluate data quality, not a perpetual free tier and not sized to run campaigns (prospeo 2026). PersistData by contrast positions one-time credit packs / month-to-month with low entry cost and no perpetual free plan; the two entry experiences differ (Lead411 = 50 exports for 7 days). |
| Annual lock-in | None; one-time packs or month-to-month | Annual plans exist and carry some lock-in friction, but a month-to-month option is available (at a higher unit price). Per Lead411's pricing page (2026), monthly Spark is cancel-anytime while annual plans require contacting support to cancel; annual is paid upfront (~$490/seat/yr Spark per the official page; older trackers say ~$900/seat/yr, another sign the third-party figures lag). Third-party trackers (prospeo, getapp, capterra 2026) report a minimum ~3-month commitment on entry plans and that Bombora intent is sold annual-only (third-party-reported, not confirmed against the current official page; flagged). prospeo (2026) reports accumulated/unused export credits are forfeited on cancellation with no payout ('all accumulated credits vanish instantly... no grace period or payout' per prospeo); attribute to prospeo, not as Lead411's stated policy. Within an active plan, trackers report unused exports roll over but cap around ~2x the monthly allocation. Auto-renewal language and the exact cancellation-notice window are not clearly documented in Lead411's public materials (prospeo notes this; flagged). Versus PersistData's no-annual-lock-in model, Lead411 pushes annual contracts (especially to unlock intent) but also offers a genuine month-to-month option, so this is a difference of degree and PersistData's no-lock-in stance is not unique. |
| API access | API-first by design; server-side, no seat | Yes, but the API is key/seat-based and gated to the Ignite tier and above (confirmed against lead411.com/pricing and syncgtm 2026). The $49/mo Spark plan has no API; programmatic access starts on Ignite (from $150/mo, or annual from $1,500/yr) and is included on Blaze. Lead411 markets a 'Sales Intelligence API' / Contact Enrichment API for CRM and proprietary-system integration (Salesforce, HubSpot, 25+ CRMs) with what it calls triple-verified emails and direct-dial enrichment. So the API is real but an upper-tier add-on rather than the core product: Lead411 is fundamentally a seat + extension UI tool with an API bolt-on, contrasting PersistData's API-first design where the API is the entire product and available from entry level. The exact API auth scheme, rate limits, and per-call pricing are not published in the sources reviewed (flagged), so we state no specifics. |
Lead411 (Lead411 Corporation, founded 2001, Boulder, Colorado) is an independent, actively maintained sales-intelligence platform that genuinely outclasses a focused enrichment API on platform breadth: its standout is affordable bundled Bombora buyer intent (annual Spark at ~$41/mo effective is among the cheaper ways to get intent data) plus daily-refreshed sales triggers (funding, hiring spikes, exec moves, tech installs), email + direct dial bundled in one export, and deep CRM integrations on lower tiers (Salesforce, HubSpot, Salesloft, Outreach, Pipedrive, 25+ CRMs). Review standing is strong and consistent (counts approximate, as of June 2026): G2 ~4.5/5 (~477 reviews), Capterra ~4.7/5 (~76 reviews), TrustRadius ~9.1/10 (~69 reviews), Gartner Peer Insights ~4.6/5 (~37 ratings), with negligible Trustpilot presence. Reviewers commonly praise data accuracy, affordability, and the intent data, while some report a base contact database smaller or noisier than ZoomInfo/Apollo and occasional UI/credit-limit friction (reviewer-reported, attributed to the platforms). On claimed database scale, brand, intent/buying signals, direct-dial coverage, CRM integrations, and end-to-end workflow, Lead411 legitimately beats a focused API like PersistData.
PersistData fits when you want a standalone, API-first data layer you call from your own software without a login, a paid per-user seat, a Chrome extension, or an annual contract: Lead411's everyday product is login + paid seat + extension, and its API is an upper-tier add-on starting at Ignite (from $150/mo), so a developer or non-Lead411 team wanting key-based programmatic access at a low entry point is the clearest place PersistData wins, along with raw price per record on pure data pulls and an explicit 'a miss = 0 credits' guarantee. Be honest about the limits: Lead411 is export-metered (you do not burn credits just searching), so it is already closer to pay-for-the-record than pay-per-attempt, and pay-for-found is offered by some other vendors too, so it is not exclusive to PersistData. Its own-database extension also carries materially lower LinkedIn-account risk than cookie scrapers, so low ban risk is largely shared, not exclusive; Lead411's no-charge-on-miss behavior is simply undocumented, so we frame pay-for-found as our confirmed policy rather than a proven contrast.
