Other Managed SDR Providers

If a managed SDR is the right model but J2 Group specifically isn't the right fit, several providers run a similar playbook at different scale.
LevelUp Leads is a California-based, fully remote agency founded in 2021. It runs multi-channel outbound across email, phone, and LinkedIn, and unlike J2 Group, it publishes a starting price for its packages rather than gating the number behind a call.
Belkins and CIENCE sit further up the scale. One independent comparison puts Belkins, founded 2017, in the $4,000 to $8,000 a month range, focused mainly on email-led outbound. CIENCE runs larger, founded 2015, with dedicated SDR teams spanning email, phone, and LinkedIn, typically starting higher and ramping into $10,000 to $25,000-plus a month depending on team size.
| J2 Group | LevelUp Leads | Belkins / CIENCE | |
|---|---|---|---|
| Pricing | Not published | Published, packages from roughly $5,000 | $4,000 to $8,000/mo (Belkins), $10,000 to $25,000+/mo (CIENCE) |
| Channels | Calling-led | Email, phone, and LinkedIn combined | Email-led (Belkins), full multi-channel at scale (CIENCE) |
| Scale | Small, named team | Full-service team per campaign | Larger dedicated SDR teams |
The trade-off within this category is rarely about quality. It's mostly about scale, channel mix, and how openly each provider prices the engagement.
Self-Serve Sales Engagement Platforms
A different path skips the managed-service model entirely. Apollo, Outreach, and Salesloft are sales engagement platforms: software your own team runs, rather than a person or agency running it for you.
These tools hand you the sequencing, the dialer, and the tracking. What they don't hand you is a trained rep. Someone on your team still has to do the calling, the messaging, and the follow-up, using the software as the engine rather than paying for someone else's headcount.
- Apollo combines a contact database with built-in sequencing and calling.
- Outreach and Salesloft focus on cadence management for teams that already have their contact data sorted.
- Salesloft and Outreach are both priced per seat, so cost scales with how many people on your team are actually using them.
Choose this path if the constraint is tooling, not headcount, meaning you already have someone who could be making the calls, but they're doing it without a system behind them.
Hiring an SDR In-House
The third path isn't a vendor at all. It's running your own hiring process: recruiting, onboarding, and managing an SDR as a direct employee, rather than renting one through J2 Group or a comparable provider.

This path takes longer. A hiring process, onboarding, and ramp-up typically run months rather than weeks, and the business carries the hiring risk directly if the person doesn't work out. There's also an ongoing cost beyond salary: management time, tooling, and the risk of losing the person to another role once they're trained and productive.
In exchange, the rep works exclusively for you from day one, with no shared attention across other clients the way a managed provider's SDR might have. Market knowledge and relationships built during the role also stay inside the business, rather than walking out the door with an outside agency's staff turnover.
This is the right call when the role is permanent enough to justify building it in-house, and the business has the time to wait for a hire rather than needing calls happening next month.
An Owned System Instead of Rented Capacity
Intelligent Resourcing doesn't sit in any of the three paths above. It isn't a managed SDR provider, a tool your team runs, or a hiring process. It builds the signal detection and CRM routing logic that decides who's worth calling in the first place, regardless of who or what does the calling.

Pricing is published rather than requiring a conversation to find out: a AUD$1,500 GTM Playbook Session to start, then a retainer running AUD$3,500 to AUD$8,400 a month. The system stays live inside the client's own CRM once the engagement ends, which none of the three paths above are built to do.

Which Path Actually Fits

The right path depends on what's actually missing. If it's calling capacity specifically, a managed SDR provider or a self-serve platform solves that, and the choice between them comes down to whether you want software or a person doing the work. If the role is permanent enough to justify the investment, hiring in-house is worth the longer timeline, since the capability stays inside the business for good.
Choosing a lead generation agency walks through that decision in more depth, including how to test which constraint you actually have before committing to a path.

FAQs
Is a self-serve tool cheaper than a managed SDR provider?
Usually, yes, since you're paying for software rather than a person's salary and management overhead. The trade-off is that someone on your team has to run the campaigns themselves.
How long does it take to hire an SDR in-house, and is that path ever the wrong choice?
A managed provider like J2 Group or LevelUp Leads can have someone calling within weeks. Hiring in-house typically takes months once recruiting, onboarding, and ramp-up are counted, so it's the wrong choice when the need is urgent or temporary rather than permanent.
Do Apollo, Outreach, and Salesloft come with any calling staff included?
No. These are software platforms. Your own team, whether existing staff or a new hire, does the outreach using the tool.
What's the real difference between LevelUp Leads and J2 Group?
Both run a managed SDR model, but LevelUp Leads publishes a starting price and runs multi-channel campaigns across email, phone, and LinkedIn, while J2 Group is calling-led and doesn't publish pricing.
Can a business combine a self-serve tool with Intelligent Resourcing?
Yes. A sales engagement platform handles execution, while a signal-led system decides who to target in the first place. The two solve different parts of the same problem.
Do any of these alternatives publish pricing the way Intelligent Resourcing does?
LevelUp Leads publishes a starting price for its packages. Belkins and CIENCE's rates come from third-party comparisons rather than their own published rate cards. J2 Group publishes no pricing at all.
