Reach a new buying team inside a familiar market

A new product can take you to a different department within companies you already know. Your sales engineers may understand the application in detail while still needing a way to reach the people responsible for it.

Coseek researches the accounts and relevant roles, builds the calling approach and prepares the rep to open that conversation. Your expertise gives us the product context and the questions that matter. We turn it into a reason to talk, so your engineers can spend their time exploring the application with a relevant buyer.

Our sales manager reviews selected calls and practises with the rep each working day. Buyer responses and your team's feedback shape the next calling block. You keep the technical discussion and the sale; we keep the research, calls and rep management moving.

AGS's broader remit is relevant when you also need work on sales execution, forecasting or the systems your team uses. Coseek is a direct fit when you want the calling campaign owned and managed, with your salespeople ready to take the conversation further.

A meeting your salespeople can prepare for

We establish account and role fit and the relevant problem, current process, timing or use case the campaign needs to uncover. The rep explains why a conversation with your specialist would help. The buyer accepts that purpose, we confirm the attendee, date and time, and send the invitation.

Your salesperson receives what the buyer discussed, why they agreed to meet and the questions still to explore. A founder can keep leading the demos, or a sales engineer can take the technical evaluation, with the first conversation's context already in hand.

Your feedback from those meetings helps us refine the campaign. That keeps the calling work connected to the people responsible for progressing the sale.

How qualification and handoff work

Start with a prepared calling campaign

Coseek typically begins with a four-week validation sprint. Research, list building and rep preparation happen before the 20 calling days. We review the conversations and meeting feedback to assess which buyers and messages are worth pursuing further.

Ongoing delivery is month to month. Where you already have sufficient market evidence and campaign inputs, ongoing calling can begin directly. We run campaigns in the US and UK; for other markets, get in touch and we can discuss your campaign.

More about the first campaign

Pricing and the first step

The official AGS homepage, lead-generation, revenue-operations and Sandler pages checked for this guide do not publish a standard campaign fee or minimum contract. Those details need to come from the proposal for your work. AGS also offers a revenue-system assessment as an initial step. AGS assessment

With Coseek, the first step is a free tailored calling plan you can share with your sales team. The script and targeting show how we would approach the market before you discuss paid execution. A private execution quote and relevant example call recordings are optional.
