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.

Why Us

Why Companies Choose BuiltDiffernt

Most outbound teams are still buying lists, sending from fragile inboxes, and hoping volume turns into pipeline. BuiltDiffernt combines deliverability, data, partnerships and our own platform to make every campaign visible, measurable and built to scale.

BuiltDiffernt is built for modern outbound.

We pair enterprise-grade sending infrastructure with partner-backed technology and live campaign transparency.

120,000,000 Emails Sent Every Year

Our sending infrastructure is built around world-class deliverability, with off-market partnerships across leading inbox providers so campaigns are set up to land, warm, monitor and scale properly.

Deep GTM Talent Network

Hundreds of go-to-market experts and consultants want to work on BuiltDiffernt client campaigns through David's LinkedIn network, giving us access to specialist talent most teams cannot reach.

World-Class Partnerships

We are closely connected with Revcode, Getleads.io, Smartlead and Instantly certified partners, giving clients access to best-in-class outbound technology and expertise.

Our Own Platform

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?

We Partner With Excellent Businesses

Martyn Lewis Founder, Market Partners Author of How Customers Buy and Why They Don’t

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 Pipeline Revenue 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 sell fake certainty. We guarantee the controllables: approved ICP, clean infrastructure, enough volume, human-written variants, reply handling, reporting and a clear market read. If the market does not respond, you know why and you keep the system.

Do you make the calls?

No. We deliver scored, qualified leads with the context behind them and your SDRs work them. Conversion rate and follow-up speed are won inside your team.

What counts as qualified?

You decide. Every contact is scored against your ICP and nothing below 8/10 makes the list, then you approve the list before a single email sends.

How do I get the 10,000 free contacts?

Book a campaign review. On the call we confirm your ICP, exclusions and qualification criteria, then we can build 10,000 contacts that are found, matched and scored against that ICP.

What if it does not work?

You will know inside 60 days with the data to prove it, and you keep the infrastructure and the market read either way.

Is there a minimum term?

Three months. Month one finds the winning angle, month two scales it, month three tells you whether the channel holds. Anything shorter is not a test, it is a sample.

Will this put our main domain at risk?

No. Everything runs from dedicated sending domains and mailboxes that are authenticated and warmed before use, kept entirely separate from your corporate mail. Your primary domain is never the thing being tested.

Who actually works on our account?

The person who sells you the programme runs it, alongside a senior go-to-market lead. There is no handoff to an account manager you have never met, which is the single biggest reason clients leave agencies in month three.
