Add calling without building another team

You may already know your buyers, have a message that gets attention and still need someone to keep the calls happening. Coseek turns that starting point into a managed campaign. We research the relevant accounts and people, prepare the script and train your assigned rep around the offer and the conversations they will encounter.

The management continues once calling begins. Our sales manager reviews selected calls and practises with the rep each working day. If buyers keep raising the same objection, we use those exchanges to work on the explanation and the next question. Your campaign benefits from what the rep learns, with Coseek responsible for putting it into practice.

Your team supplies product knowledge, account exclusions and feedback from sales meetings. We handle the research, calling and coaching. You can keep your existing marketing running and your experienced sellers focused on taking opportunities forward.

How Coseek runs the calling operation

Know how your business will sound on the phone

The rep needs to explain your offer in words a buyer would use, listen to the answer and recognise a useful reason to continue. We prepare the rep to discuss the situations your product or service addresses and ask questions that reveal whether there is a relevant need.

Before a meeting is booked, we establish the agreed problem, current process, timing or use case. The buyer accepts the purpose of the next conversation, we confirm the attendee, date and time, and send the invite. Your salesperson receives the call context, so they can prepare for the discussion.

You can request relevant example recordings with your free game plan. Hear how our reps handle a conversation, then read the complete script proposed for your own campaign. That gives you something concrete to assess before hiring us.

What AltiSales offers

AltiSales' homepage describes three programs for starting or improving an SDR team:

ProgramPublished approach
StartUp GTM LaunchA program for a new team, with eligibility criteria and a mix of monthly fees, commission-based work and possible investment.
GTM AccelerationSupport for an existing team of 1 to 10 SDRs to improve its sales-development process.
Boost & Scale UpWork on the efficiency of a team with 5 or more SDRs, including calling, sequences and ramp.

Its fractional services include hiring, compensation-plan work, account distribution, data research and RevOps. Data Operations IP specifically covers helping a company hire, train and manage its own researchers, with workflows and tools for that work. These are relevant options when you want to develop a function your team will operate.

AltiSales also provides outsourced delivery. Its sales-development guide describes account research, calls, email and social contact, qualification and handoff to the client's sales team. Outsourcing is available from both providers. Coseek's offer centres on a calling campaign with an assigned rep, campaign preparation and daily sales management.

Begin with a prepared, four-week campaign

We typically start with a four-week cold-call validation sprint. Research, list building and rep preparation happen before the 20 calling days begin.

During the campaign, we review who we reach, what buyers say and the meetings your team takes. We use that evidence to improve the targeting and conversations and recommend the next step. Ongoing delivery is month to month. If you already have an established calling campaign, ongoing work can begin directly.

FAQ

How much does AltiSales cost?

AltiSales publishes starting prices for individual fractional services, rather than a single monthly price for a complete outsourced SDR campaign. Data Research is priced according to volume; hiring is based on hiring volume and a percentage of salary. A proposal is needed for the combined scope and billing schedule. Its startup program has a separate commercial structure.

Can Coseek use our existing list and messaging?

Yes. Your account knowledge, customer profile and previous campaign experience are useful inputs. We use them to prepare the calling campaign, research the relevant people and refine the message as we learn from conversations. We exclude the customers, active opportunities and other accounts you need to protect.
