The Premier B2B Lead Generation Agency for Businesses That Have Product-Market Fit

B2B lead gen agencies, admittedly, get a bad rep. There’s nothing we do that good agencies aren’t already doing, we’re just honest about what is (and what isn’t) achievable.

Bad copy

Hi Sarah,

We help businesses get more leads through cold email.

Do you have 15 minutes next week?

Any Other Agency
Good copy

Saw you are hiring two SDRs while expanding into clinics.

We helped a similar healthcare SaaS book qualified demos without adding another rep.

Worth testing one segment before you commit the headcount?

Market Partners

30 Meetings in Five Weeks for an Enterprise Client

The client on this engagement was a 250,000-employee technology enterprise that could not ask its own customers how they buy. We reached the open market instead, across industries, and got strangers to commit half an hour each. 27 of the 30 gave the same answer, and that answer set the direction for everything after it.

Linen and More

$200,000 in Pipeline in Six Weeks

Bed linen manufacture, selling into bedding e-commerce. Bought lists and cold LinkedIn had returned nothing at all across two years. Campaigns went live in April 2026 against a list narrowed to stores whose actual product is bedding, and inside four months there were hundreds of replies and five to six live negotiations running at once.

Got Any Questions?

Frequently Asked Questions

Do you guarantee meetings?

No. We do not guarantee meetings, pipeline or revenue. We run cold email campaigns, generate replies and qualify leads against criteria agreed before launch. Results depend on the market, offer, data, deliverability, timing and how quickly your team follows up.

Do you make the calls?

No. BuiltDiffernt is cold email only. We do not act as your SDR team, run discovery calls or close deals for you. We hand qualified opportunities to your team with the context needed to follow up properly.

What counts as qualified?

A qualified lead is agreed before launch. Usually that means the company fits your ICP, the person is relevant, and the reply shows interest, intent or a clear next step. A contact on a list is not automatically qualified or billable.

What happens on the sales call?

It is a 30-minute fit call. We look at your offer, target market, deal value, sales process and budget, then decide whether cold email is likely to work. If it is a fit, we agree the plan, pricing and next step on the call.

What if it does not work?

We diagnose the part of the system that is blocking results: data, offer, copy, inbox performance, replies, qualification or sales follow-up. Then we adjust the campaign with you. If the market does not respond after a fair test, we tell you plainly.

Is there a minimum term?

Yes. The minimum term is three months because cold email needs enough time to test data, messaging, inbox health and follow-up quality. Month one proves the angle, month two improves volume, and month three shows whether the channel can hold.

Will this put our main domain at risk?

We use dedicated sending domains and inboxes, with authentication, warm-up and monitoring, so campaign activity is separated from your main corporate domain. No email programme can promise zero risk or guaranteed inbox placement.

Who actually works on our account?

You work with the people responsible for the campaign strategy, build, launch and optimisation. That covers targeting, data, infrastructure, copy, reply review and reporting. Your team owns the sales conversations after handoff.
