How to use this comparison hub
If you're picking between B2B lead gen agencies, the right answer is rarely the best-known name. It's the one that fits your stage, market, and what you actually need under contract. Below: 27 honest comparisons grouped by category.
Managed agencies
Book the team. They run outbound for you and either book the meetings or hand you the replies. Best when you don't want to hire SDRs in-house. Belkins, Sopro, Cience, memoryBlue (formerly Operatix), Callbox, SalesHive, Martal Group, Cleverly and ORRJO sit here.
Data and outreach platforms
Software your in-house team operates. Cognism, ZoomInfo, Apollo and Lusha sell B2B contact data and prospecting tools. Outreach and Salesloft are revenue platforms for prospecting, deals and forecasting. You supply the SDRs.
What to check in each one
Who books the meeting, which channels run, the published price and the contract term. These differ a lot between suppliers, so read each company's own pricing and terms pages before you compare totals.
Compare ORRJO with managed agencies
Direct head-to-head with the agencies most ORRJO prospects also evaluate.
Compare ORRJO with data and outreach platforms
Tools your in-house SDR team operates. You buy the data and software; your team runs the outreach.
Compare ORRJO Intelligence with research and competitive intelligence providers
Software and services for competitive intelligence and win-loss research, set against ORRJO Intelligence.
What separates ORRJO from the field
Three things ORRJO does that are worth testing in any head-to-head.
Demand gen can run first
ORRJO Demand Generation runs webinars, ABM warming, founder LinkedIn ghostwriting and content ahead of outreach, so the brand is recognised by the time SDRs call. Across all clients, ORRJO runs at 90%+ meeting attendance.
Brand and content under one roof
ORRJO Brand & Content rebuilds website, deck, and LinkedIn alongside outbound so the first thing a prospect Googles after your SDR call is congruent. Brand builds and full website rebuilds are priced on the call, both depending on the scope of the project.
UK and EU compliance native
Headquartered in Glasgow. Campaigns run in ORRJO's private CRM environment, EU hosted and run under GDPR, and call lists are screened against TPS and CTPS.
When to choose someone else
Honest take. ORRJO is not always the right answer.
Choose Belkins if
You want a larger, longer-established team for omnichannel appointment setting. Belkins' about page says it was founded in 2017 and reached 300 people by the end of 2022, and its pricing page lists packages of 100+ and 200+ appointments a year.
Choose Cognism or Apollo if
You already have a strong in-house SDR team and need data and software rather than a managed service. Cognism sells B2B contact data, and Apollo describes itself as an AI GTM system covering data, intelligence and execution.
Choose memoryBlue (formerly Operatix) if
You sell B2B software. Operatix's homepage says “Our client portfolio consists 100% of B2B Software vendors” and lists coverage across North America, LATAM, EMEA and APAC. memoryBlue acquired Operatix in 2023, and memoryBlue's site says Operatix now operates fully under the memoryBlue brand.
Choose Sopro if
You want your own team to work the positive replies, on no minimum contract. Sopro's pricing page says there is “no minimum contract”, and its services page says positive replies come straight back to your inbox.
Choose Cleverly if
You want done-for-you LinkedIn, cold email or cold calling from a low published starting price. Cleverly's LinkedIn lead generation page says its services “start at $397 per month”.
Choose ORRJO if
You're a UK or EU founder, you want brand and outbound to land together, and you want 90%+ meeting attendance.
Frequently asked questions
Three questions. One: do you want a tool you operate or a team that delivers meetings? Two: which markets and languages do you need covered? Three: do you need brand, demand generation or research as well as outbound, or just outbound? Then check each supplier's own website for who books the meeting, its published price and its contract terms. ORRJO books qualified meetings and sells Demand Generation, ORRJO Intelligence and Brand & Content alongside Lead Generation.
It depends what you need. Belkins was founded in 2017 and runs omnichannel appointment setting, with a demand generation service alongside. Its about page lists offices in Delaware, Colorado, Illinois and London, and its pricing page lists packages without prices. ORRJO was founded in Glasgow in 2022, prices every service on the call, and sells Brand & Content and ORRJO Intelligence as well as Demand Generation. Read the full ORRJO vs Belkins comparison.
It depends who you want to book the meeting. Sopro suits teams that want to work positive replies themselves, on no minimum contract: its pricing page says there is no minimum contract, and its services page says positive replies come straight back to your email and LinkedIn inbox. ORRJO suits teams that want qualified meetings booked for them, with 90%+ meeting attendance and Demand Generation and Brand & Content from the same team. Read the full ORRJO vs Sopro comparison.
Cognism sells B2B contact data, which its homepage calls Europe's most trusted B2B data for growing pipeline. ORRJO is a managed agency. Use Cognism if you have an in-house SDR team and need contact data. Use ORRJO if you want qualified meetings booked without building an in-house team. Read the full ORRJO vs Cognism comparison.
Cience runs managed SDR teams, including outbound SDR pods and high-volume scaled outbound programmes, and also sells demand generation and ads. Its about page says it is headquartered in Miami, Florida, and that graph8 acquired the assets of CIENCE. ORRJO is headquartered in Glasgow, has 45+ people, and runs Lead Generation alongside Demand Generation, ORRJO Intelligence and Brand & Content.
ORRJO works across 15 countries from its Glasgow headquarters, and its outreach runs in English. Several agencies here describe wider language coverage on their own websites: memoryBlue, which acquired Operatix in 2023, lists 30+ languages, Callbox runs multilingual SDR teams, and Cience says its operators work across more than 10 languages. If your campaign is US-only, Belkins lists three US offices and Cience is headquartered in Miami.
