Where to find outbound sales campaigns for B2B SaaS companies in the UK

Why UK B2B SaaS Companies Struggle to Source Outbound Campaigns

Building an outbound sales motion is one of the fastest ways to grow a SaaS company, but most UK founders don’t know where to find campaigns that actually work. You can hire a sales development team yourself, but recruiting, managing, and training talent takes 4-6 months and costs £40k-60k per month. You can also outsource to traditional agencies, but many charge retainers regardless of results. Neither path gives you the speed or flexibility that early-stage SaaS needs.

The real question isn’t whether you should run outbound—it’s where to find teams that deliver meetings without the overhead.

The Five Main Channels for Sourcing Outbound Campaigns

1. Freelance Marketplaces (Upwork, Fiverr, Freelancer)

You’ll find plenty of outbound specialists on freelance platforms, but quality varies wildly. Most offer list building and email sequences, not actual cold calling or live conversations. Conversion rates from these campaigns typically fall between 2-5%, which is below industry benchmarks.

The real risk: you’re buying time, not results. A freelancer might send 1,000 emails, but you have no accountability for whether those prospects actually engage with your product.

If you go this route, insist on performance tracking from day one. Ask for call recordings, email open rates, and reply-to-meeting conversion rates. Don’t pay for volume; pay for qualified conversations.

2. Traditional Sales Outsourcing Agencies

Companies like SalesDrive, Martal Group, and similar UK-based agencies handle your entire outbound motion. They’ll research your ICP, build lists, run campaigns, and qualify leads. This is the “done-for-you” option.

The trade-off: retainers start at £5k-15k per month, with 12-month commitments standard. You get professional execution, but you’re locked into their cadence and methodology. Typical conversion rates sit around 6-10% reply rate, 15-25% meeting conversion from those replies.

These agencies work well if you have budget and can wait 90 days for momentum. They’re less ideal if you need to test different ICP segments or pivot messaging quickly.

3. Pay-Per-Meeting Models (Emerging)

A newer wave of companies charges you only for booked meetings, not activity. Glencoco operates this way in the UK—you connect with real cold calling teams through a marketplace, and you only pay when a prospect actually books time with you.

This flips the incentive structure. Instead of a team padding hours, they’re optimized for conversion, not calls made. If your typical sales cycle closes at 12-15% of meetings, you’re looking at a meeting cost of £50-200 depending on your ICP complexity and industry.

The advantage: zero risk if a campaign doesn’t work. You stop paying immediately. The disadvantage: you need a solid sales process on your end. If you convert at 3% of meetings instead of 12%, the per-booking cost explodes.

4. In-House Hiring Through Talent Platforms

Workable, LinkedIn Recruiter, and Indeed let you hire SDRs directly. This gives you control but requires management overhead. A junior SDR costs £22k-28k annually in the UK; a mid-level SDR costs £28k-40k plus commission.

You’ll need 2-3 months of onboarding before they’re productive. During that window, you’re paying for training, not results. Once ramped, a solid SDR generates 8-15 qualified meetings per month depending on industry and ICP quality.

Only choose this path if you’re planning to scale to 5+ SDRs. Otherwise, blended cost per meeting is higher than outsourcing.

5. DIY Cold Calling (Your Founders)

If you have time, you can run your own cold calling campaign using Phantom Buster, Apollo.io, or Instantly for list building and outreach infrastructure. You’ll learn your ICP fast, and every lesson is yours to keep.

The reality: this works for the first 100-200 conversations, then it scales poorly. Your time is better spent closing deals, not making calls. Most founders who try this discover they’re naturally better at different parts of the sales process.

Choosing the Right Channel for Your Situation

Early stage (pre-revenue to £10k MRR): Start with pay-per-meeting or freelance specialists. Low cost, high control, zero overhead.

Growth stage (£10k-50k MRR): Either hire your first SDR or partner with a traditional agency. You need consistency and accountability at this scale.

Scaling (£50k+ MRR): Build a hybrid: 2-3 in-house SDRs + outsourced cold calling for testing new segments. This gives you efficiency and experimentation capacity.

What to Look For in Any Outbound Campaign

Regardless of channel, demand these non-negotiables:

Targeting clarity. The team running your campaign must articulate your ICP in writing before day one. Ask: what companies? What job titles? What company size and revenue range? If they’re vague, walk.

Transparent metrics. You need weekly tracking: calls attempted, conversations had, reply rates, meeting bookings, and most importantly, cost per booked meeting. If a vendor won’t share this, they’re hiding poor performance.

Industry experience. Fintech and insurtech outbound is different from general B2B. Make sure whoever runs your campaign understands your vertical’s pain points, deal cycles, and buyer psychology.

Responsiveness to feedback. A good campaign evolves. Your first messaging won’t be perfect. The team should be willing to iterate on scripts, targeting, and cadence based on early data.

Why Most Outbound Campaigns Fail

Three reasons, in order:

First: weak ICP definition. You’re calling too broad, and most prospects don’t fit your product. Tighten your target ruthlessly.

Second: generic messaging. Your cold call or email sounds like everyone else’s. Reference the prospect’s company, recent funding, job change, or industry trend. Personalization drives 3-5x higher reply rates.

Third: no sales process on your end. The campaign books 20 meetings. You have no qualifying framework, no demo script, no follow-up system. Half the prospects disappear. That’s a campaign failure misattributed to the outreach team.
