AltiSales is a serious outsourced SDR and GTM acceleration firm. It can make sense when you want help building, optimizing, or eventually insourcing an outbound sales development motion.
Coseek is narrower. It is built for B2B teams that mainly want decision-makers reached by phone, qualified meetings booked, no retainer, no setup fee, and payment tied to meetings delivered.
The decision is not whether AltiSales is credible. It is whether you want a broader SDR system-build partner or a focused pay-per-qualified-meeting cold calling partner.
Coseek lens
The useful comparison is not who has the bigger team. It is what you pay for before a qualified sales conversation exists.
AltiSales vs Coseek at a glance
| Dimension | AltiSales | Coseek |
|---|---|---|
| Primary model | Outsourced SDR, GTM acceleration, consulting, training, and data operations | B2B cold calling for qualified meetings |
| Channels | Calls, email, LinkedIn, data research, RevOps, and playbook work | Phone, with responsive post-call emails after real conversations |
| Pricing | Custom, retainer, project, or program pricing depending on scope | Pay per qualified meeting |
| Commitment | Broader program or team-build engagement | No retainer or setup fee |
| Best fit | Teams building, revamping, or insourcing an SDR function | B2B teams that want sales conversations and booked meetings |
| Qualification | Qualified leads, meetings, pipeline, SDR efficiency, and team KPIs | Qualified meeting criteria defined upfront |
| Ownership outcome | Can transfer playbooks, workflows, and IP back to the client | Client owns prospect relationships and meeting handoff context |
AltiSales is built around SDR system improvement. Coseek is built around qualified meetings from phone-led outbound.
If you need a repeatable SDR engine, AltiSales may fit better. If you mainly need qualified meetings without funding a retainer first, Coseek is cleaner.
What AltiSales does
AltiSales positions itself around outsourced SDR, GTM acceleration, sales development consulting, data operations, RevOps, and outbound system improvement.
Its SDR outsourcing page describes a flow from research and contact information, to sequences and strategy, to outreach, scheduling meetings, and qualification as a potential buyer. It also says clients can get a dedicated SDR, email templates, call scripts, LinkedIn messaging, and multichannel plays.
The consulting page lists GTM Accelerator, SDR Outsourcing, Fractional Leadership, Data Research, Data Ops Strategy, Outreach Setup Optimization, audits, playbook creation, outbound messaging, and RevOps strategy.
That is a broader engagement than hiring a vendor to make calls. AltiSales can help build or improve the operating system behind outbound.
AltiSales pricing and contract model
AltiSales does not publish core SDR outsourcing retainer pricing on the checked official pages.
Its consulting page does publish starting prices for specific audits: a Potential Spam Phone Audit from $1,500 for 15 numbers, and Phone Call Success and Email Deliverability audits from $7,500. Its homepage Startup GTM Launch offer says it charges a small monthly fee, does mostly commission-based work, and may invest $50,000 to $300,000 for qualifying startups.
G2 says pricing details are not currently available. SalesHive's vendor profile describes custom, project-based, and retainer-based pricing, but that is third-party profile context rather than an official price card.
Coseek uses a different unit. Coseek charges $500 to $2,000 per qualified meeting for B2B clients. There is no retainer, no setup fee, and no B2B success fee. The first invoice arrives after qualified meetings are booked.
The buyer question is not which option is cheaper. It is whether you want to fund a broader SDR buildout or pay only when qualified meetings are booked.
Where AltiSales is likely the better fit
AltiSales is likely the better fit if you want to build or improve the SDR function.
Choose AltiSales if:
- You want to build or rebuild the SDR motion, not only outsource calls.
- You need consulting around outbound strategy, SDR process, RevOps, Outreach setup, dashboards, compensation, or playbooks.
- You want a multichannel program across phone, email, LinkedIn, and data operations.
- You have an existing SDR team that needs coaching, call-flow analysis, funnel diagnostics, or efficiency improvement.
- You may eventually want to insource the playbook, workflows, and operating model.
- You are an early-stage SaaS company that fits their Startup GTM Launch criteria and wants a partner that may participate with commission-heavy or investment-backed economics.
That model can be right when the gap is not just meetings. It is the sales development system itself.
Where Coseek is likely the better fit
Coseek is likely the better fit if you want phone-led qualified meetings without a broader system-build project.
Choose Coseek if:
- You want to test or scale B2B cold calling without a monthly retainer.
- Your ACV supports $500 to $2,000 per qualified meeting.
- You care more about qualified meetings than SDR headcount, lead volume, or a full outbound system-build project.
- You already know the ICP well enough to start calling.
- You do not want to buy email, LinkedIn outreach, RevOps consulting, SDR training, or broad GTM advisory from the same vendor.
- You want call context passed into the handoff: role, company fit, pain, current stack, objections, and next step.
- You want responsive post-call emails only after real conversations.
Coseek is not a replacement for AltiSales' consulting model. It is a narrower way to buy qualified meetings from the phone channel.
The real difference is scope plus pricing model
AltiSales is built for improving or operating an SDR system. Coseek is built for booking qualified meetings by phone.
A broader SDR program can be right when your team needs process, management, tooling, data operations, and eventual in-house transfer.
A performance model is cleaner when your team already knows who to call, has sales capacity to take meetings, and wants vendor risk tied directly to booked qualified meetings.
Use the math.
If your Coseek qualified meeting price is $1,000 and 10 qualified meetings produce one closed deal, meeting-fee CAC is $10,000 before internal sales cost. If your first-year ACV is $50,000+, that can be a defensible acquisition cost.
That is not a promised close rate. It is the model to test.
Meeting quality standards to compare before choosing an outsourced SDR partner
Before choosing AltiSales, Coseek, or another outsourced SDR partner, define the billable unit.
At Coseek, a qualified meeting has to clear four checks:
- Title or role matches the agreed list.
- Company matches the agreed target criteria.
- Specific date and time confirmed.
- Calendar invite sent.
Then ask every vendor:
- What counts as a qualified meeting?
- Are you paying for SDR capacity, leads, appointments, or qualified meetings?
- Is qualification based on role and company fit before the meeting, or on downstream pipeline outcome?
- What call context arrives with the calendar invite?
- Who owns follow-up after a conversation?
- What happens if a booked prospect cancels or no-shows?
- Is your goal to build a better internal SDR function, or to add qualified meetings to the calendar?
The questions are simple because the buying choice should be simple.
Is Coseek the right AltiSales alternative?
Coseek is worth a call if you sell B2B with meaningful ACV, already know the market you want to reach, and want phone-first outbound with no retainer and payment tied to qualified meetings.
AltiSales may be better if you want outsourced SDR capacity, GTM acceleration, RevOps consulting, outbound playbooks, SDR training, or eventual handoff of the operating model to your internal team.
The clean split:
- Choose AltiSales if you want to build or improve a broader SDR system.
- Choose Coseek if you want focused B2B cold calling and only want to pay when qualified meetings are booked.
