What is De Grijff B.V.?
De Grijff B.V. is a Netherlands-based business development partner that positions itself around niche and technical B2B sales support. Their homepage title calls them "Jouw Business Development Partner," and their site says they help improve B2B sales with a data-driven strategy, smart software, and a personal approach.
(Note: at the time of writing, De Grijff B.V. has no published client reviews or public pricing, so this profile reflects its stated services rather than third-party verified outcomes.)
From the public information available, De Grijff serves a wide mix of client types including enterprise, startups, mid-market, scaleups, and SMBs. In the Instantly partner directory, De Grijff B.V. is listed as a certified partner and is associated with industries including financial services, manufacturing, IT services, B2B services, legal services, sustainability, and SaaS. Their site also claims to support "more than 150+ companies worldwide" and says it is trusted by "more than 500+ sales professionals," but those are company claims rather than independently verified review data.
What is Outbound Pros?
Outbound Pros is a founder-led managed outbound agency focused on turning outbound into a controlled, measurable acquisition system. I built it to run email and LinkedIn together as one coordinated sequence, with replies landing in Primebox so sales teams are not juggling disconnected channels.
The core specialty is deliverability. We set up dedicated owned domains per client, document SPF, DKIM, and DMARC, warm accounts for 4-6 weeks, and target 85-95% inbox placement before scaling. The operating stack is modern and practical: Salesforge for sending, Clay for enrichment and AI personalization, Leadsforge plus Apollo for sourcing, Warmforge for warm-up, and Agent Frank as an optional AI SDR layer.
Operationally, onboarding takes about 21 days. We typically use month 1 for infrastructure and months 2-3 to ramp toward 15-30 meetings per month. Clients get a live dashboard plus a monthly interpreted report covering volume, quality, funnel progression, and ROI.
Where does De Grijff B.V. win?
De Grijff B.V. wins on broader business development positioning. Their site does not present them as only a cold email shop. Instead, they frame the offer around continuity in sales, structured follow-up, data insights, and support from strategy to execution.
De Grijff also appears well aligned for niche and technical business development. Their homepage explicitly asks whether you are looking for a partner in niche and technical business development, which is a useful signal if your product needs more context-heavy conversations.
They also have a credible cold email angle. Being listed as a certified partner in the Instantly partner directory suggests they are a vetted agency in that ecosystem, which matters if you specifically want an agency already recognized within a known outbound sending platform.
Where does Outbound Pros win?
Outbound Pros wins when the main job is predictable outbound execution with strong inbox placement. Deliverability is not a side topic for us. It is the system. That matters if your team has already felt the pain of burned domains, spam placement, or inconsistent reply quality.
We also win on channel coordination. Outbound here is not email in one tool and LinkedIn in another with no shared logic. We run email and LinkedIn as one sequence and route replies into Primebox, which creates cleaner handoff and less rep confusion. If you are deciding how those channels should work together, this guide on linkedin vs email when to use which channel for b2b outbound 2026 gives the operating logic behind that model.
Transparency is another real difference. Clients get a live dashboard plus a monthly interpreted report, so they can see not just activity but how volume, quality, funnel movement, and ROI connect.
We also tend to fit buyers who want senior operators close to the work. Outbound Pros is founder-led, with less appetite for burying execution behind an account layer.
Finally, our stack is built for modern outbound. Clay-based enrichment and AI personalization, optional Agent Frank support, and a practical sourcing plus warm-up stack make sense for teams that want current tooling without stitching it together themselves. If AI SDRs are part of your evaluation, our ai sdr buyer guide 2026 is a useful companion.
Pricing: De Grijff B.V. vs Outbound Pros
Pricing is the difference between public clarity and private discussion. De Grijff B.V. does not publish pricing on the sources provided, so if you are evaluating them you will likely need a sales conversation to understand package structure and scope.
Outbound Pros is more explicit. Our service-based pricing runs from $1.5K to $10K per month, with common tiers around $1.5K, $3K, and $5K. For trust-based accounts, we also offer a hybrid retainer plus $25-$50 per meeting above a baseline.
That does not automatically make one cheaper than the other. It simply means Outbound Pros is easier to pre-qualify on budget before a call.
Who should choose De Grijff B.V.?
De Grijff B.V. is a fit for buyers who want a business development partner rather than a narrowly defined outbound engine. If your sales issue is continuity, structured follow-up, and getting more process around business development, their positioning lines up with that need.
It also makes sense to consider them if you sell into one of the verticals named in their directory profile, such as financial services, manufacturing, IT services, legal services, sustainability, or SaaS, and you want an agency that speaks in terms of niche or technical business development.
If you prefer to buy from a Netherlands-based team and value a local partner in that market, De Grijff is the more obvious choice on geography.
Who should choose Outbound Pros?
Outbound Pros is a fit for teams that already know outbound should be a measurable acquisition channel and want specialists to run it well. If your priorities are domain health, inbox placement, coordinated email plus LinkedIn, and transparent reporting, that is exactly where we are strongest.
We are especially useful for founders and sales leaders who do not want cold calling as the core service and would rather build around email-and-LinkedIn-first outbound. The fit is strongest when you want owned infrastructure, fast visibility into campaign health, and a team that can move from setup to ramp without a long strategy-only phase.
