NewcoSignal vs Seamless.AI

Seamless.AI is a contact data platform for sales teams. Its own pricing page did not render the table when we checked, so the figures here come from third-party sources in 2026: a free plan with 50 one-off lifetime credits, the Basic tier removed, and Pro on quote, annual contracts, for a minimum of five users, typically $4,740 to $9,000 a year for five users, with a custom Enterprise plan. Treat these as indicative.

That is a team-sized, contract-based product. For a solo adviser, a small agency or a two-person sales team, the first question is usually how to find companies worth contacting, not how to reveal more contact data for companies already in a database.

NewcoSignal handles that first question for new UK companies. We ingest Companies House daily and let you filter by industry category and region. A saved search emails you the new matches daily or weekly. The free plan has unlimited company search and one saved search with a daily email of the top 5 new matches, and every new account gets a 14-day Pro trial with no card. Pro, at £39 per month + VAT or £348 a year + VAT, covers every match (up to 625 new companies a week), with 10 saved searches, CSV and Excel export, Zapier, webhooks, Slack and Teams.

A new company comes with a registered address (around 99.98%) and a named director (around 99%), with formation-agent addresses and likely shell companies filtered out and a reachable-by-post filter for mailings. We do not claim emails or phone numbers for brand-new companies, because a company incorporated last week seldom has them, and we show a contact email or website only where verified. Instant alerts are hourly delivery of daily data, not real time.

If you already use a contact data platform, NewcoSignal is a cheap way to add a source of companies in their first days. Business, at £99 per month + VAT, includes native CRM sync for HubSpot, Pipedrive, Zoho, Capsule and Dynamics 365 and an API, so new companies can flow straight into the system your team already uses.
