Compare B2B Agencies
Honest, side-by-side comparisons of 18 B2B lead generation, demand gen, SDR, and outreach platforms. Where ORRJO wins. Where it doesn't. Where the real differences sit, with no fluff and no astroturfed reviews.
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: 18 honest comparisons grouped by category.
Book the team. They run outbound and book meetings. Best when you don't want to hire SDRs in-house. Belkins, Sopro, Cience, Operatix, ORRJO sit here.
Self-serve tools your in-house team operates. Cognism, ZoomInfo, Apollo, Lusha, Outreach, Salesloft. Lower per-meeting cost, but you supply the SDRs.
Cleverly, SalesHive, Martal Group, Callbox. Smaller teams, narrower focus, often by channel (LinkedIn-only, cold email-only).
Direct head-to-head with the agencies most ORRJO prospects also evaluate.
Tools your in-house SDR team operates. Lower upfront cost, more execution risk.
Three structural differences that show up in every head-to-head.
Most lead gen agencies start with cold outbound. ORRJO runs LinkedIn campaigns, content, and audits ahead of outreach so the brand is recognised by the time SDRs call. The gap shows in attendance: 90%+ vs the 50-60% UK industry average.
Belkins, Sopro, Cience, and Operatix don't touch your brand. ORRJO Creative Studio rebuilds website, deck, and LinkedIn alongside outbound so the first thing a prospect Googles after your SDR call is congruent.
UK-based, GDPR and PECR-compliant from day one. Most US-headquartered agencies treat compliance as a bolt-on. ORRJO has run UK campaigns since 2022 with zero ICO complaints upheld.
Honest take. ORRJO is not always the right answer.
Your campaign is US-only, you need a longer track record, or you want a 200-person agency with named industry pods. Belkins is older, larger, and US-led.
You already have a strong in-house SDR team and you just need data plus a sequencing platform. Tools beat managed services on per-meeting cost when you have the in-house engine.
You're enterprise tech with a 6-figure ACV and need a US-UK-APAC SDR pod targeting Fortune 500 buyers exclusively.
You want pure cold email at scale, you don't need brand or creative, and you accept industry-standard 50-60% meeting attendance.
You want LinkedIn-only outreach at low monthly cost. Narrow scope, narrow price, narrow result.
You're a UK or EU founder, you've been burned by agencies before, you want brand and outbound to land together, and you want 90%+ meeting attendance instead of 50%.
Three questions. One: do you want a tool you operate or a team that delivers meetings? Two: is your priority US scale or UK and EU compliance and quality? Three: do you need brand and creative as well as outbound, or just outbound? Map your answers against each agency's positioning. ORRJO wins on managed delivery, UK and EU focus, and integrated brand-plus-outbound.
ORRJO is the closest UK alternative to Belkins. Belkins has a longer US track record. ORRJO is UK-headquartered, GDPR-native, and integrates brand plus demand gen with outbound. Read the full ORRJO vs Belkins comparison.
Sopro is the right choice if you want pure email at scale and accept 50-60% attendance. ORRJO is the right choice if you want demand gen ahead of outbound, 90%+ attendance, and brand built alongside. Read the full ORRJO vs Sopro comparison.
Cognism is a data and outreach platform. ORRJO is a managed agency. Use Cognism if you have an in-house SDR team and just need contact data plus sequencing. Use ORRJO if you want booked meetings without the cost and management of an in-house team. Read the full ORRJO vs Cognism comparison.
Cience is US-based and operates at scale through dedicated SDR pods. ORRJO is UK-based, smaller, and integrates demand gen and creative with outbound. Cience suits high-volume US outbound. ORRJO suits UK, EU, and quality-over-volume founders.
ORRJO services 15+ countries from a UK base, with strongest concentration in UK, EU, and US East Coast. If your campaign is US-only, Belkins and Cience have larger US-native teams. If your campaign is APAC-only, Operatix has stronger APAC coverage. For UK and EU, ORRJO is the clear choice.
