Belkins Alternatives: 7 B2B Lead Generation Agencies Compared

The best Belkins alternatives depend on what you are buying: meetings, deals, or a full revenue engine. This guide compares seven B2B lead generation agencies, VirtuWise and six other names buyers shortlist, and gives you the criteria to separate them. We run one of the seven, so we say so up front and keep claims about the others to what you can verify yourself.

Why Do Buyers Look for Belkins Competitors?

Buyers look for Belkins competitors because shortlisting more than one vendor is standard practice for a retainer of €3,000 a month or more. Three triggers come up repeatedly: a need for different market coverage (EU and UK rather than US only), a need for deal support beyond the first meeting, or a wish to compare pricing structures before signing.

Searching for alternatives is not a signal that something went wrong. It is procurement. Comparing three to five vendors on the same criteria takes about two weeks and protects a budget that will run for at least six months.

What Should You Compare Across B2B Lead Generation Agencies?

Compare agencies on outcomes, not activity. Reply volume and email opens tell you a campaign is running. Qualified meetings, opportunities created, and revenue tell you it works.

Use six criteria on every vendor:

• Definition of a qualified meeting: who signs it off, you or the agency?
• Channels: LinkedIn, email, or both, and who owns the sending infrastructure.
• Scope after the meeting: handoff, or full-cycle support through proposal and close.
• Market fit: experience in your region and vertical, such as fintech, iGaming, SaaS, or IT services.
• Contract terms: monthly retainer, minimum term, and what happens if you leave.
• Reporting: weekly pipeline numbers, not monthly activity summaries.

A vendor that cannot answer all six in writing is not ready for your budget.

Which 7 B2B Lead Generation Agencies Are Worth Shortlisting?

Seven names belong on a shortlist for this search: VirtuWise, Belkins, Martal Group, SalesRoads, SalesAR, Sopro, and Keystrike AEO. We have not tested the others and we publish no claims about their pricing, features, or results. Check each against the six criteria above using their own proposals.

1. VirtuWise. A Europe-based growth partner covering outbound, SEO and AEO, and fractional growth leadership. Outbound starts from €3,000 a month; details follow in the next section.
2. Belkins. The reference point of this comparison. Evaluate it on the same six criteria as everyone else.
3. Martal Group. A B2B lead generation agency. Ask for its definition of a qualified meeting and its reporting cadence.
4. SalesRoads. An outsourced sales development provider. Ask which channels it runs and how handoff to your team works.
5. SalesAR. A B2B lead generation agency. Ask for market and vertical fit in writing.
6. Sopro. An outbound-focused agency. Ask for contract length and exit terms.
7. Keystrike AEO. A UK-based provider with an answer engine optimization focus. Ask how its scope connects to pipeline, not just visibility.

Treat this list as a starting point. Request the same one-page proposal from each, then score them side by side.

How Does VirtuWise Compare With the Other Agencies?

VirtuWise is built around outcomes, not activity. We run three pillars: outbound, inbound, and a fractional growth partner for the revenue engine behind both.

Outbound covers ICP research, verified prospect lists, LinkedIn and email outreach, reply handling, meeting booking, and weekly reporting, from €3,000 a month. Business development extends that into full-cycle sales support through proposals, negotiations, and closing, from €5,000 a month. SEO and AEO starts from €3,500 a month and covers keyword research, content, technical SEO, structured data, llms.txt, and AI crawler access.

If you want to see how we run the first pillar, read our B2B lead generation services page. Our focus is not the number of messages sent, but the number of qualified conversations your sales team can close.

We serve fintech and payments, iGaming, B2B SaaS and AI, IT services, and logistics technology across the EU, UK, and US. Outside those profiles, another agency may fit better. We would rather tell you that on a first call than after a signed contract.

Which Agency Fits Which Buyer?

Match the agency to the gap in your revenue engine. The right choice for a team with strong closers and no meetings differs from the right choice for a team with no sales capacity at all.

• You have closers, need meetings: a pure outbound retainer fits. Compare the definition of a qualified meeting first.
• You have meetings, lose deals: you need full-cycle business development, so verify scope after the meeting.
• You have neither positioning nor pipeline: start with an audit of ICP, funnel, and revenue engine before paying for outreach volume.
• You want compounding inbound demand: SEO and AEO belongs in the scope, not as an afterthought.

How Do You Run the Comparison in Two Weeks?

Run it in four steps with fixed dates. Open-ended evaluations drift for months and end in no decision.

1. Days 1–2: write your ICP and your definition of a qualified meeting on one page.
2. Days 3–5: send that page to three to five agencies and request the same proposal format.
3. Days 6–10: hold one call per agency and ask the six criteria questions in the same order.
4. Days 11–14: score every proposal and decide, or run a paid pilot of 60 to 90 days with a clear pass or fail target.

The pilot target should be an outcome, such as qualified meetings booked, not emails sent.

Frequently Asked Questions

Are Belkins alternatives cheaper?

No, not by default. Price depends on scope, not on vendor name. Our outbound scope starts from €3,000 a month, and full-cycle business development starts from €5,000. Compare what each price includes before comparing the number.

What is the best lead generation agency for tech companies?

The best fit is the agency that has sold into your buyer's role and region. Technology buyers are skeptical and reply to relevance, not volume. Ask each vendor for its ICP research process and who approves a meeting as qualified.

How many agencies should I compare?

Compare three to five. Fewer than three gives you no baseline. More than five stretches the process past two weeks without improving the decision.

Should I choose an agency for outbound or for SEO and AEO?

Choose by the gap you have today. Outbound produces meetings within weeks; SEO and AEO compounds over months. Many B2B teams need both, which is why we scope them together.

Which Agency Will Earn Its Retainer?

The one that answers all six criteria in writing and agrees to be measured on qualified meetings, not activity. Want a second opinion on your shortlist? Talk to the team at VirtuWise and we will map your gap to a scope, even if the answer is another agency.
