Key takeaways
- Seamless.AI describes itself as a real-time search engine for sales leads.
- Lusha reveals emails and phone numbers through a browser extension, CRM integrations, an API and MCP.
- How recently a record was checked is a question to put to each vendor directly.
- Pebbles Ai finds work emails at 1 to 10 named companies a run, with no phone numbers.
Real-time contact search vs a database: what is the difference
The difference is where each product puts the work: Seamless.AI builds around a search engine that looks up sales leads in real time, while Lusha reveals details from its data inside tools you already use. Around that search, Seamless.AI lists three products: a Data Engine, an Engagement Hub and AI Agents.
Lusha meets the seller in the browser and the CRM. Its extension and CRM integrations show emails and phone numbers on the record in front of you, and its API and MCP server let a developer or an AI tool pull the same data into other systems.
Lusha vs Seamless.AI: the strengths of each
Seamless.AI's strength is a focused, quick lookup for individual prospects: search for the person you are after and get their contact details back. A free start with limited credits lets you judge the search on your own targets.
Lusha's strength is reach into the tools a team already has open. Phone numbers come alongside emails, lookups happen within the browser and the CRM, MCP access opens the data to AI tools, and a free tier covers a first trial.
Which one suits your sales team
Choose Seamless.AI if your reps start each day with names to look up and want a search engine built for that lookup; choose Lusha if they want details to appear in the browser and CRM they already work in. Phone-led teams should look closely at Lusha, which lists phone numbers on its pricing page.
A team that feeds other systems has a further reason to look at Lusha's API and MCP. As an illustration, a revenue operations lead wiring contact lookups into an internal tool cares more about that access than about a search screen.
Where Pebbles Ai fits as the third choice
Pebbles Ai fits a team that would rather describe its targets once than look people up one at a time. An assistant can first find companies that match your ideal customer, up to 50 a search, and Find fresh leads then returns the right people at up to ten of them, from Pebbles Ai's own growing B2B contact database, GDPR compliant. Each lead arrives in the built-in CRM, labelled Beta, with personalisation angles drawn from public LinkedIn posts, falling back to role and company.
It does not fit a seller who needs phone numbers, or a quick lookup for one person in the middle of a call. Pebbles Ai has no browser extension and no phone data; its work is the batch of leads, the research and the drafted outreach that follow.
Questions to ask both vendors about fresh data
Ask each vendor how a record is found and how it is kept up to date, because a current record matters more to a seller than a long feature list.
- When a contact is returned, how recently was it checked?
- What happens to a record when the person changes jobs?
- How are lookups counted against your credits?
- Which CRM does the data reach, and by what route?
- What do the vendor's trust pages say about personal data in your countries?
