A UK-built alternative to Lead411 — for teams that just need signals and a message.
We don't compete with Lead411 feature-for-feature. We do something narrower, for a specific UK B2B use case, at a much lower price point. Here's the honest version of where each tool wins.
What Lead411 actually is
A US-focused B2B contact and intent-data platform aimed at outbound sales teams, with a published-trigger feed for things like funding, hiring and growth.
When Lead411 is the right choice
- Your buyers are predominantly US-based.
- You want trigger feeds bundled with a contact database in one tool.
- Outbound at scale is your primary motion.
We'd rather you choose the tool that fits the problem than churn off Thawly in 60 days.
Where Thawly wins
- Thawly is UK-only. Lead411's UK public-data coverage is materially lighter than its US trigger feed.
- Thawly is purpose-built for the lost-deal use case, not for cold outbound.
- Thawly doesn't sell contact data — by design.

Comparison reflects published positioning at the time of writing. Tooling moves fast — if a row is out of date, email hello@thawly.co.uk and we'll update it.
A daily email — only when something fired — listing the companies on your lost-deal list with new signals, ranked by score. Each entry has a short Claude-drafted re-engagement message tuned to your industry. Three actions per entry: copy, snooze, dismiss.
Migrating from a contact-database tool
The migration path is short because there's no migration. You don't move contact data into Thawly — there's nowhere to move it to. You upload a CSV of companies you already track and Thawly starts watching them. Whatever contact tooling you keep keeps working.
Most teams who add Thawly do so as a complement, not a replacement. The all-in-one tool stays for outbound; Thawly takes over the closed-lost workflow.
Frequently asked
Is Thawly a direct replacement for Lead411?+
Not in every case. Lead411 a us-focused b2b contact and intent-data platform aimed at outbound sales teams, with a published-trigger feed for things like funding, hiring and growth. Thawly is a narrower, signal-first tool focused on UK companies you already care about. Many UK teams use both, with Thawly slotted in for closed-lost re-engagement.
Can I migrate my existing list across?+
Yes — upload a CSV. Company name and a few deal details is enough. Company records are resolved against the UK's authoritative business registry automatically, with a verification email so you can confirm the auto-matches.
How does pricing actually compare?+
Thawly's published pricing starts at £49/mo with a 14-day free trial and scales up to £299/mo for 5,000 companies. Lead411 pricing is typically not published; quote-based and seat-based contracts are common. The two products solve different problems, so direct price comparison is misleading.
Are these comparisons fair?+
We try. We don't reproduce Lead411's logo, don't make claims we can't back up, and explicitly call out where Lead411 is the better choice. If you spot something inaccurate, email hello@thawly.co.uk and we'll correct it.
