Describe your business once. Knockwire reads the internet, throws out the companies that are a waste of your time, and knocks on the doors of the ones that are not. Starting with their contact form.
No card. First 100 knocks free. Built by the team behind Crawlbase.
Every one scored against your profile, not a keyword.
The number that matters. Noise you never had to look at.
Real fit, with the evidence attached so you can check.
Two had no legitimate contact route. We said so.
This runs on what you actually type. Write two lines about your business and Knockwire will build the profile it would go to work with, including who it plans to throw away.
Waiting on a description.
Two sentences is enough to start.
Anything that fails a gate is dropped with a written reason, and you can read every rejection. That is how you find out whether the profile is wrong.
Knockwire reads the company the way a person would: what they sell, who to, at what size, on what stack. An agency that resells to your competitors looks identical to a customer in a keyword search. It is not one, and this gate is where that gets caught.
Fit without timing is spam with good aim. It looks for the trigger: a role posted, a stack change, a funding note, a page that says they are doing the thing your product fixes. No trigger, no knock.
A public contact form, a sales page, a stated route in. If the only way in is around a control someone put there on purpose, the company is marked unreachable and you are not charged. Knockwire does not defeat access controls.
Suppression list, contact history, and the rules where the recipient actually sits. Several jurisdictions require prior consent even between businesses. Those are excluded before anything is written, not after.
A cold email lands in a filtered inbox. A contact form lands in a channel a person is paid to monitor. We started where the reading happens, and we are honest about what is not built yet.
Found, filled, and submitted through residential IPs in the right geography, at human pace, with your identity attached and the full payload logged.
Same judgment layer, same suppression list, pointed at a verified address when the form is not the right door. Warmup and deliverability handled.
The channel is the cheap part. The profile, the scoring, and the suppression history are the asset, and they carry across all of them.
Automated outreach has a deserved reputation problem, earned by tools that blast forms with no ceiling and no record. The restraint here is not a setting you can switch off, and that is the point of the product.
Per period, by default. You can loosen it. You cannot remove the ceiling entirely.
Jurisdictions requiring prior consent for business contact are excluded until you deliberately opt in.
Real company name and a working reply address on every message. No anonymous sends.
Protected form, marked unreachable, no charge. We do not solve challenges to get through a door.
One request removes a company across every campaign in your account and every future run, permanently.
Timestamp, payload, route, and response, retained and exportable for when someone asks what you sent.
Reading four thousand companies to find eleven is our cost to carry, not yours. Unreachable doors are never billed either, which is what lets us refuse one without losing your money.
Enough to judge the messages before you spend anything.
For a team running continuous outbound without an ops hire.
Volume, dedicated IP pools, and paperwork procurement will accept.
Prices in US dollars, billed monthly and renewing until cancelled. Sales tax or VAT is calculated at checkout. Cancel any time; every charge carries an unconditional 30-day refund.
It depends where the recipient sits. Business to business contact through a published form is generally permitted in the US and much of the world. Several EU states, notably Germany and Italy, require prior consent even between businesses. Knockwire excludes those regions by default and you adjust the policy deliberately. This is not legal advice and you should confirm your own position before sending at volume.
Because you can audit it. Every rejection carries a written reason and every approval carries the evidence it was based on. If the profile is wrong you will see it in the rejection log within the first hundred companies, which is why the free tier includes the full log rather than only your wins.
Those tools optimise for volume through a filtered channel. Knockwire optimises for the opposite: reading a lot, sending very little, through a channel someone is paid to monitor. If you want to send ten thousand messages a week, we are the wrong product.
Form submissions do not touch your sending domain the way cold email does, which is a large part of why the channel works. Your exposure is with recipients themselves, which is what the per company ceiling and the suppression list exist to protect.
The team that built Crawlbase, a web crawling and proxy platform running since 2017 with more than 46,000 paying customers. Knockwire runs on that same residential network, which is why we can afford to read four thousand companies to find eleven. Crawlbase was also our first customer, and it still is.
Yes, and most teams start there. Upload domains, company names, or URLs and Knockwire runs the same four gates over them, tells you which ones it would have rejected on its own, and contacts the rest.
Write two sentences about your business, read the profile it builds, and look at what it throws away. That is the entire evaluation.
