BuiltDiffernt review
Builds and runs it
BuiltDiffernt is where the domain listed as The Prospect Agency now redirects. It is run by founder David Sinclair-Black and sells cold email and nothing else: its FAQ says it does not make calls, act as an SDR team or close deals. It builds the sending infrastructure, sources and scores leads, writes the copy and hands qualified leads to your team.
The pricing is the unusual part. Each plan is a monthly minimum, $5,000, $12,500 or $25,000, credited towards per-lead fees agreed before launch, so the buyer pays extra only when accepted leads exceed the minimum. Leads and replies are tracked in Bob, its own dashboard and shared inbox.
It is candid in places. The FAQ states that meetings, pipeline and revenue are not guaranteed, and the case study page explains that one headline figure counted research conversations rather than sales opportunities.
Who BuiltDiffernt is for
B2B companies doing $10M+ in revenue with product-market fit, a sales team that follows up quickly, and a budget of at least $5,000 a month for three months. The sales call page asks buyers to bring their offer, sales numbers and whoever approves the spend.
Calls and closing stay with the client, since the FAQ says BuiltDiffernt does neither, so the fit is a team that wants email handled and nothing more. A company that wants the system installed in-house can buy that on the Scale plan, for a separate fee.
Strengths and limits
What it does well
- Publishes three plan minimums with sending volumes attached: 100,000, 300,000 and 700,000 cold emails a month
- The monthly minimum is credited against per-lead fees, so a buyer is not paying a retainer and a performance fee on top of each other
- States plainly that meetings, pipeline and revenue are not guaranteed and that it does not make calls
- Its case study page explains what each headline number measured, including that 30 'meetings' were research interviews
Where it falls short
- Handing the system over is a separate $25,000 one-time fee, listed on the $25,000-a-month Scale plan
- Ownership of domains, inboxes and data is agreed in each scope, and a service page warns buyers not to assume a monthly plan transfers every asset
- Cold email is its sole channel, with no LinkedIn or calling
- Its homepage proof section still shows an unfinished entry reading 'TODO: sector and timeframe to be supplied'
BuiltDiffernt pricing
Three plans are published. Starter is a $5,000 monthly minimum for up to 100,000 cold emails across three segments, Growth is $12,500 for 300,000 across five, and Scale is $25,000 for 700,000. Each minimum is credited towards qualified-lead fees, with the per-lead rate and the lead criteria agreed before launch.
Scale adds a one-time $25,000 fee for installing the system and handing it to your team after the campaign. The minimum term is three months, so the smallest commitment is $15,000.
What you keep, and what counts as a result
Domains, inboxes, data and workflows
Does not say who owns the infrastructure
We found nothing on its site about whether the sending domains, inboxes, lists and workflows are yours when the engagement ends. That is the most common answer in this directory, and it is recorded as silence, not as a finding against the company. Ask before signing.
The unit of a result
Sells positive replies or leads
Publishes 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.”
Guarantee, as published: None. Its FAQ states: 'We do not guarantee meetings, pipeline or revenue.'
This records what BuiltDiffernt publishes about itself, read in September 2026. It is not an assessment of what the company does in practice.
Verdict
Paying against accepted leads, with the monthly minimum credited towards the fees, is the draw for an established B2B company that wants cold email run by specialists. A buyer who values a supplier that writes down what it will not promise will find that in the FAQ. The published minimums and the agreed lead criteria make the commercial terms easy to test before signing.
The $10M revenue floor and the email-only scope close the door to smaller companies and to anyone who wants calls or LinkedIn in the mix. Owning the infrastructure costs a $25,000 handover on the Scale plan; outside it, ownership is negotiated rather than stated.
Others worth a look
This is an independent review. BuiltDiffernt is not a client or a partner, we have no affiliate relationship with them, we earn nothing if you hire them, and nobody pays for placement in the directory. Prices were read from the company's own pages in September 2026 and change without notice.
