Leadbro AIFind real leads.
Write the email.
Paste a company website. We read it, work out who buys from them, search the web for ten companies that fit and look up a published email for each, then hand you the best five to write to.
10 websites free. Google sign-in, no card, no checkout.
Four steps, and you approve every one
Nothing is written until you have seen who it is going to. Nothing is sent until you press send.
Analyse site
We read the homepage and up to five inner pages, then work out what the company sells, who buys it and why.
Find leads
A web search for companies that genuinely fit that profile — with the source link for each, so you can check.
Draft email
One email per selected company, written only from facts that appeared in the research. No invented details.
Send
From your own domain, or ours with replies routed to you. One at a time, with a pause between each.
It doesn't make things up
Most of the engineering here went into what the model is not allowed to do.
Email addresses are not part of what it is allowed to return. They come from the company's own published pages, or from a verified lookup.
An address is used only if it appears on the company site or comes back from the resolver as safe. Plausible guesses are dropped, not kept.
you@example.com, info@yourdomain.com and the rest of the template detritus are filtered out before they can reach a card.
If we cannot establish who the person is, you get the role. You will never send to a person the model made up.
The reason a company was proposed is shown next to a link to where that came from, so you can check it in one click.
The postal address and the opt-out line are appended by the application, never by the model, so they cannot be forgotten or reworded.

Before you sign up
Where do the email addresses come from?
From the company's own published pages — contact and about pages, and the site's own scripts — cross-checked against a resolver. The model is never allowed to supply one, so it cannot invent one.
Do the emails go out as me?
On the free plan the From address is info@techub.kr and the Reply-To is your own address, so replies come straight to you. We do that because techub.kr is the only domain we are authorised to sign for: SPF and DKIM pass, the mail arrives, and nobody can send under your company name but you. Connect your own Resend key or SMTP server and it sends as you instead.
Can I use my own sending setup?
Yes, on any plan. Add a Resend API key or your own SMTP server (Gmail, Workspace, Zoho, Fastmail, or your own) in Settings. Your key is encrypted before it is stored and is never shown back to you or to us in full.
What counts as one of my ten websites?
Each website you analyse. If a site cannot be read — it is unreachable, or built entirely in JavaScript — that attempt is refunded automatically and does not count.
Is this compliant?
We append the postal address and an opt-out line to every message in code, which is what CAN-SPAM requires. You are the sender: you are responsible for who is on your list and for the law where your recipients are, which in the EU and UK means more than a footer.
What happens when the trial runs out?
Nothing is deleted and nothing is locked. Everything you have already run stays fully usable — you can keep drafting and sending those leads. You just cannot add an eleventh website until you talk to us.

Takes about a minute. You will see the profile it builds before anything else happens.
