Quick answer
Growth Room vs Outbound Pros is a comparison of two B2B outbound lead-generation agencies with different strengths.
Growth Room appears positioned as a broader French/English growth and outbound agency for SMBs, especially B2B services and IT companies. Their site and directory profiles point to multichannel outbound, CRM and RevOps support, ABM, and even Ads and SEO. Outbound Pros is narrower by design. We run founder-led managed outbound focused on coordinated email and LinkedIn, with deliverability infrastructure as the center of the system.
If you want one partner that can touch outbound, CRM, and wider acquisition, Growth Room has a credible case. If you want senior operators, owned sending setup, unified reply handling, and a channel mix built around inbox placement rather than calls, Outbound Pros is the better fit.

What is Outbound Pros?
Outbound Pros is a founder-led managed outbound agency built for B2B teams that want email and LinkedIn run as one coordinated system.
I built Outbound Pros around a simple idea: outbound breaks when infrastructure, targeting, messaging, and reply handling live in separate silos. So we run email and LinkedIn together, and replies land in Primebox, our unified inbox workflow. We do not do cold calling as a core service.
Our core specialty is deliverability. We set up dedicated owned domains per client, document SPF, DKIM, and DMARC, warm domains for 4 to 6 weeks, and target 85% to 95% inbox placement before we push volume.
The operating stack is modern and practical: Salesforge for sending, Clay for enrichment and AI personalization, Leadsforge and Apollo for sourcing, Agent Frank as an optional AI SDR layer, and Warmforge for warm-up. Clients get a live dashboard plus a monthly interpreted report on volume, quality, funnel, and ROI. Onboarding takes about 21 days, and campaigns usually spend month 1 on infrastructure before ramping toward 15 to 30 meetings per month in months 2 and 3.
Where does Growth Room win?
Growth Room wins when a company wants a broader acquisition partner, not just an outbound execution team.
First, their scope is wider. Their site and partner profile point to outbound, CRM/RevOps, ABM, Ads, SEO, and HubSpot support. If you want one agency that can connect prospecting to a wider growth stack, that breadth is real.
Second, they support more outbound channels in the published offer. The directory listing says cold email, LinkedIn, and calls. For teams that already believe calling should be part of the mix, that is a meaningful difference from Outbound Pros.
Third, they have visible third-party social proof and public entry pricing. A 4.9/5 rating from 8 reviews on the Lemlist expert directory and a listed outbound price around €3,500/month give buyers more public reference points than many agency profiles do.
Where does Outbound Pros win?
Outbound Pros wins on outbound operating depth for buyers who care most about inbox placement, channel coordination, and hands-on execution.
First, deliverability is our center of gravity, not a side note. We use dedicated owned domains per client, set up SPF, DKIM, and DMARC, and warm accounts for 4 to 6 weeks before ramp. The Growth Room data provided here does not publish that level of infrastructure detail.
Second, we treat email and LinkedIn as one sequence with one reply layer. Replies land in Primebox, which makes handoff and follow-up cleaner than splitting channels across tools and inboxes. If you care about coordinated touches, that matters more than just saying "multichannel."
Third, our reporting is built for operating decisions. Clients get a live dashboard plus a monthly interpreted report that covers volume, quality, funnel, and ROI. Growth Room does mention custom dashboards, and that is a positive, but our reporting format is explicitly tied to outbound performance management.
Fourth, the team model is senior and founder-led. That matters for buyers who do not want a strategy pitch sold by one person and then passed to a junior account layer.
Fifth, our stack is explicitly AI-native. Clay for enrichment and personalization plus optional Agent Frank gives us more flexibility in how we build and test campaigns. If that is a priority, you may also find our review of linkedin outreach tools compared useful when evaluating execution maturity.
Pricing: Growth Room vs Outbound Pros
Pricing is where these two agencies are easier than average to compare because both sides have at least some public guidance.
For Growth Room, the Lemlist expert directory lists multichannel outbound at about €3,500 per month and consulting or training at 3,500. I would treat that as directional rather than a precise custom quote, since directory listings can lag behind a live sales process.
For Outbound Pros, our service-based pricing runs from $1.5K to $10K per month, with common tiers around $1.5K, $3K, and $5K. We also offer a hybrid model with a retainer plus $25 to $50 per meeting above a baseline for trust-based accounts.
If you want a broad growth agency retainer with outbound inside it, Growth Room's listed price may make sense. If you want pricing that can align more directly with meeting production while still covering infrastructure and senior execution, Outbound Pros gives more flexibility.
If your benchmark is pure meeting output, our guide on cold email follow up sequences that convert is a good companion read because pricing only matters if the sequence design gets replies.
Who should choose Growth Room?
Growth Room is a fit for SMBs that want outbound connected to a wider growth engine.
Choose Growth Room if you want one agency that can combine prospecting with CRM or RevOps work, ABM, and paid acquisition. They also make sense if your team wants calls included in the outbound mix, or if you prefer a French or bilingual French/English agency context. B2B services and IT companies appear to be the clearest fit based on their directory positioning.
They are also a sensible option for buyers who value public third-party reviews and a visible starting point on pricing before taking a sales call.
Who should choose Outbound Pros?
Outbound Pros is a fit for B2B teams that want outbound execution built around deliverability and reply flow, not channel sprawl.
Choose us if your team wants email and LinkedIn managed as one coordinated motion, with owned infrastructure, clear inbox placement standards, and senior operators close to the work. We are especially strong for founders, lean sales teams, and revenue leaders who want a specialist rather than a broad growth agency.
We are also the better fit if cold calling is not central to your plan, if you want a live dashboard plus interpreted monthly reporting, or if you want hybrid pricing that can align part of the fee to meeting output.
If You're Comparing Options
Comparing agencies is really about matching the operating model to the job you need done.
Growth Room looks credible for SMBs that want multichannel outbound inside a broader growth and RevOps relationship. They have public reviews, a listed outbound price point, and a wider scope than most cold email shops.
Outbound Pros wins for buyers who want specialist depth in managed outbound, especially where deliverability, owned infrastructure, and unified email plus LinkedIn execution are the deciding factors. That is the lane we are built for.
If that sounds like your use case, start with our managed outbound service and see if the model matches how your team wants to scale pipeline.
