5 Best Done-for-You Lead Gen Agencies for B2B in 2026

Not every B2B company has the resources, expertise, or desire to build a lead generation engine in-house. Hiring SDRs, managing outreach tools, maintaining email deliverability, sourcing data, writing sequences, and continuously optimising — it's a full operation. And building that operation from scratch takes months before you see consistent results.

Done-for-you lead generation agencies exist because of that reality. They take the entire prospecting workload off your plate and deliver meetings with potential buyers. You focus on closing deals and serving customers while the agency fills your pipeline.

But the market is crowded, and the quality varies enormously. Some agencies deliver a genuine stream of qualified conversations. Others flood your calendar with low-quality meetings that waste your sales team's time. Choosing the wrong partner costs you months and thousands of pounds in wasted investment.

We evaluated the leading done-for-you lead generation agencies operating in 2026 and selected five that consistently deliver results. We're honest about each one's strengths and limitations — including our own. The goal is to help you find the right fit, not to sell you on one particular option.

How We Evaluated These Agencies

We assessed each agency on five core factors that determine whether a done-for-you lead gen partnership will actually work for your business.

Lead quality. The most important metric. It's easy to book meetings — it's hard to book meetings with people who are genuinely interested, actually qualified, and ready to have a substantive conversation. We prioritised agencies known for delivering meetings that convert into pipeline, not just meetings that pad a report.

Targeting methodology. How does the agency identify prospects? Pure firmographic targeting (industry, size, title) is table stakes. We gave preference to agencies that layer in additional intelligence: intent signals, behavioural data, technology tracking, or event-driven targeting. The more precisely an agency can identify the right prospect at the right time, the better the meeting quality.

Transparency and communication. Done-for-you doesn't mean done-in-the-dark. Good agencies share what they're doing: which lists they're targeting, what messages they're sending, how campaigns are performing, and what they're learning. We favoured agencies with clear reporting and regular communication.

Flexibility and contract terms. Some agencies lock you into 12-month contracts with aggressive minimums. Others offer month-to-month or short commitment periods. We considered how easy it is to start, adjust, and exit each partnership.

Client fit. Different agencies serve different markets. An agency that excels with enterprise software companies may not suit a 10-person consulting firm. We evaluated who each agency serves best and flagged the ideal client profile for each.

1. Totalremoto

Model: Intent-based done-for-you lead generation.

Totalremoto (that's us) takes a different approach from traditional appointment-setting agencies. Instead of starting with a static list and sending cold outreach, we start by monitoring buying signals — intent data that tells us which companies are actively researching solutions like yours. We then send personalised outreach to the right decision-makers at those companies and book meetings on your calendar.

What we do well. The core strength is signal-based targeting. Because we're reaching prospects who are already showing buying intent, the meetings tend to be higher quality — the prospect has pre-existing awareness of the problem and is more ready to have a real conversation. Our outreach is heavily personalised, referencing the specific signal that triggered the approach. We handle email and LinkedIn, manage all deliverability infrastructure, and qualify responses before booking.

Limitations. We're honest about these. Totalremoto is a smaller operation than agencies like Belkins or CIENCE, which means we can't handle the same volume of simultaneous campaigns. Our intent-based model also means the total pool of prospects at any given time is smaller — we're only reaching companies showing buying signals, not your entire addressable market. If you need 50 meetings per month and your TAM isn't enormous, our model may not produce that volume. We also don't yet have the years of published case studies that more established agencies can point to.

Best for: B2B companies selling considered purchases (SaaS, consulting, professional services, agencies) that prioritise meeting quality over volume. Teams of 5–100 employees where the founders or senior sellers are closing deals and need a reliable pipeline without building an internal SDR team. Companies that want their outreach to stand out from the flood of generic cold emails their prospects receive.

Pricing: Competitive with mid-market done-for-you agencies. Pricing varies based on the scope of signal monitoring and outreach volume. See our plans or book a call for details.

2. Belkins

Model: Outbound appointment setting.

Belkins is one of the most established names in done-for-you B2B lead generation. Founded in 2017, they've built a large-scale appointment-setting operation that serves hundreds of clients across many industries. Their core service is straightforward: they build prospect lists, write outreach sequences, send emails and LinkedIn messages on your behalf, and book meetings on your calendar.

What they do well. Belkins' greatest strength is their operational maturity. They've run campaigns across hundreds of verticals, which gives them deep pattern recognition about what works. Their copywriting is consistently strong, their processes are well-documented, and they have the team size to handle multi-campaign engagements. They also publish excellent content about outbound best practices, which demonstrates genuine expertise. Their client portfolio is impressive and diverse.

Limitations. Belkins' model is fundamentally volume-driven outbound. They build lists based on firmographic criteria and run cold outreach campaigns. This means you'll get a mix of meeting quality — some conversations will be excellent, others will be with prospects who took the meeting out of curiosity rather than genuine interest. Belkins is also a larger operation, which can mean your account gets less individual attention than you'd get from a smaller agency. Their pricing has moved upmarket in recent years, reflecting their established position.

Best for: mid-market B2B companies that need a reliable flow of meetings and have sales teams capable of converting cold appointments into opportunities. Works well for companies entering new markets or verticals where broad outreach is valuable for testing messaging and generating early pipeline. Particularly strong for companies comfortable with a traditional outbound motion.

Pricing: typically starting around $3,000–$5,000/month with minimum contract terms. Pricing varies based on the scope and number of campaigns.

3. CIENCE

Model: Multi-channel outbound with data research.

CIENCE positions itself as a "people-as-a-service" outbound platform. They combine dedicated SDR teams with a proprietary data research team and technology stack. The model is more labour-intensive than many competitors — CIENCE provides actual human SDRs who work as an extension of your sales team.

What they do well. CIENCE's research capability is a genuine differentiator. Their data team manually researches and verifies prospect information rather than relying solely on database pulls. This results in cleaner lists and better deliverability. They also offer multi-channel outreach: email, phone, LinkedIn, and even direct mail, which gives them more touchpoints than email-only agencies. Their GO Data platform provides additional enrichment and intent signals. For companies that need a full SDR team without hiring one, CIENCE's model provides real human beings who can have conversations, not just automated email sequences.

Limitations. The human-intensive model means higher costs. CIENCE is typically more expensive than agencies that rely primarily on automated email campaigns. Quality can vary depending on which SDR team is assigned to your account — as with any people-dependent service, individual performance matters. Their complexity can also be a drawback for smaller companies that just want simple, focused outreach without a multi-channel operation.

Best for: companies that want a true outsourced SDR team with phone-calling capability alongside email and LinkedIn. Strong for B2B companies in industries where phone outreach is still effective (manufacturing, professional services, enterprise software). Particularly valuable if your sales process benefits from human-to-human conversations early in the funnel.

Pricing: typically in the $5,000–$10,000/month range, reflecting the labour-intensive model. Contracts tend to be quarterly or annual.

4. Martal Group

Model: Sales-as-a-service with dedicated account executives.

Martal Group offers what they call "sales-as-a-service" — going beyond appointment setting to provide dedicated account executives who can handle the entire top-of-funnel process. They target primarily B2B technology and SaaS companies and have built a team of experienced sales professionals who understand the tech buying process.

What they do well. Martal's team members tend to have genuine sales experience, not just SDR training. This means the conversations they have with prospects are more substantive, and the qualification is tighter. They also offer a "pay per lead" option, which is unusual in the space and attractive for companies that want to tie their investment directly to outcomes rather than activity. Their technology focus means they understand SaaS and tech selling cycles well — ICP definitions, competitive landscapes, and buyer personas in the tech space.

Limitations. Martal's tech focus can be a limitation if you're outside the technology sector. While they do serve other industries, their deepest expertise is in B2B tech. Their pay-per-lead model sounds attractive but requires careful definition of what counts as a "qualified lead" — if the criteria aren't aligned, you may end up paying for meetings that don't meet your standards. As a mid-size agency, they may not have the bandwidth for very high-volume or enterprise-scale engagements.

Best for: B2B technology and SaaS companies that want more than appointment setting — they want skilled salespeople representing their brand in early-stage conversations. Particularly good for companies that want to test a pay-per-lead model before committing to a larger monthly retainer. Works well for companies with average deal sizes above $25K where individual conversation quality matters significantly.

Pricing: retainer models starting around $3,000–$5,000/month, with pay-per-lead options available. Pricing depends on the complexity of your ICP and the expected deal size.

5. SalesRoads

Model: Appointment setting with phone-first outreach.

SalesRoads is a US-based appointment-setting agency that has been operating since 2007 — one of the longest-running companies in this space. Their core differentiation is their emphasis on phone-based outreach, combined with email and LinkedIn. In an era where most lead gen agencies have moved to email-first (or email-only), SalesRoads maintains that phone conversations produce higher-quality appointments.

What they do well. SalesRoads' phone-first approach genuinely works in markets where decision-makers still answer the phone or respond to voicemails: healthcare, manufacturing, financial services, government-adjacent businesses, and traditional B2B industries. Their SDRs are US-based and trained to have real conversations, which matters for companies that need their brand represented by articulate, knowledgeable professionals. Their longevity in the market is itself a credential — they've survived multiple cycles of outbound evolution and adapted their approach.

Limitations. Phone-based outreach is less effective in industries where buyers don't answer unknown numbers — which is increasingly common in tech, SaaS, and digital-first businesses. SalesRoads' model is labour-intensive, which means higher costs and potentially slower scaling. Their approach may feel "old school" compared to AI-driven and intent-based models, though there's nothing wrong with approaches that work. Geographic coverage is strongest in North America.

Best for: B2B companies in traditional industries where phone outreach is still the norm: healthcare, manufacturing, logistics, financial services, and enterprise-grade products. Particularly good for companies with average deal sizes above $50K where a phone conversation is the natural first step. Works well for companies that value US-based SDR teams and are willing to invest in a phone-first approach.

Pricing: premium pricing reflecting the US-based, phone-first model. Typically $5,000–$10,000/month depending on the campaign scope and SDR allocation.

How to Choose the Right Agency for Your Team

Choosing a done-for-you lead gen partner is a significant decision. Here's a framework for thinking about it clearly.

Start with your sales motion. How does your sales team actually close deals? If your reps thrive on phone conversations, SalesRoads or CIENCE (which include phone outreach) may be the best fit. If your buyers primarily engage through email and LinkedIn, Belkins, Totalremoto, or Martal Group are better aligned. Match the agency's outreach channels to where your buyers actually live.

Consider your deal size and sales cycle. If you're selling a $5K/year SaaS product, volume matters — you need a lot of meetings to move the revenue needle. Belkins' high-volume model or Martal's pay-per-lead option may make more sense. If you're selling $50K+ consulting engagements with 6-month sales cycles, quality matters more than quantity. Totalremoto's intent-based approach or CIENCE's research-heavy model may deliver better ROI per meeting.

Evaluate your internal capacity. How many meetings can your sales team actually handle per week? There's no point booking 20 meetings per week if your two salespeople can only take 8. Be honest about your conversion capacity and choose an agency whose volume matches it. Better to have 10 high-quality meetings your team can properly follow up on than 25 meetings where half go stale.

Ask about transparency. Before signing, ask each agency: "Can I see the emails you're sending on my behalf? Can I see the prospect lists? Can I see performance data by campaign?" If the answer is anything other than "yes," that's a warning sign. You should always know what's being said in your name and who it's being said to.

Start with a manageable commitment. If possible, start with a 3-month engagement rather than a 12-month contract. Good agencies are confident enough in their results to offer shorter initial terms. Use the first 3 months to evaluate meeting quality, not just meeting volume. The true test is: are these meetings turning into pipeline and revenue?

Frequently Asked Questions

How long before a done-for-you agency delivers results?

Expect 4–8 weeks before meetings start flowing consistently. The first 2–3 weeks are onboarding: defining your ICP, building lists, writing messaging, setting up infrastructure. Weeks 3–5 typically produce the first meetings. Consistent, optimised flow usually arrives by month 2–3. Any agency promising significant results in week one is either overselling or has an unusual model.

What's a reasonable cost per meeting to expect?

This varies by industry, deal size, and agency model. A rough benchmark: $200–$500 per meeting from a volume-focused agency (Belkins, CIENCE). $300–$800 per meeting from a quality-focused agency (Totalremoto, Martal). The meaningful metric isn't cost per meeting — it's cost per qualified opportunity and ultimately cost per closed deal. A $500 meeting that converts to a $50K deal is infinitely better than a $200 meeting that goes nowhere.

Should I choose an agency that specialises in my industry?

Industry experience is helpful but not essential. An agency that's run successful campaigns for SaaS companies can probably run one for your SaaS company. But an agency that's specifically worked with, say, cybersecurity vendors selling to enterprise CISOs will have a head start on ICP definition, messaging, and targeting. Prioritise targeting methodology and communication quality over industry specialisation — a good agency learns your industry quickly.

What if the meetings aren't converting into deals?

This is the most important question. If you're getting meetings but they're not converting, the issue could be lead quality (wrong people), lead timing (not ready to buy), or your sales process (how you handle the meeting). Work with your agency to diagnose the problem. Share meeting outcomes transparently — tell them which meetings were great and which were poor, and why. A good agency will adjust targeting and messaging based on this feedback. A bad agency will just book more meetings without improving quality.

Can I use a done-for-you agency while also running my own outbound?

Yes, but coordinate carefully. The main risk is reaching the same prospects through both channels — which looks unprofessional and can damage your brand. Share your target account lists with the agency and agree on territory rules: who's reaching out to whom. Some companies use the agency for new market outreach while their internal team focuses on existing accounts and upsells. That division usually works well. Book a call with Totalremoto if you'd like help designing a coordinated approach.
