Internal build
Hire and build the function
Recruit the rep, add management, buy the data and tools, build the phone operation, then wait for the team to ramp before the market produces useful evidence.
Highest setup cost and longest path to evidenceROI calculator
Model a four-week cold-calling sprint using your ACV, qualified-meeting scenario, close rate and sales-cycle timing. Then compare the result with the cost and delay of building the function internally.
Run the numbers01 / Calculator
The output follows the four-week meeting scenario to gross meeting value, expected wins, probability-weighted revenue and break-even economics.
02 / Build vs buy
Salary is only one line. The useful comparison includes the people, operating system, setup time, and pipeline delayed while the function is being built.
Internal build
Recruit the rep, add management, buy the data and tools, build the phone operation, then wait for the team to ramp before the market produces useful evidence.
Highest setup cost and longest path to evidenceValidation sprint
Use a four-week test to learn whether the segment, buyer, offer and message produce enough qualified conversations to justify a larger motion.
Fastest way to reach a scale, revise, or stop decisionOngoing campaign
Keep one campaign active with the rep, GTM engineering, sales management, phone infrastructure, qualification, and reporting working as one function.
Built for consistent market coverage03 / Methodology
The meeting is the first commercial handoff your sales team can assess. The model then applies your contract value, close rate, sales-cycle timing and the sprint investment.
meetings × ACVThe combined contract value represented by the meeting scenario before close rate is applied. It is not CRM-stage pipeline.
meetings × close rateThe statistical closed-won scenario created by your own historical close rate.
gross meeting value × close rateA probability-weighted scenario based on your close-rate input, not a forecast or guarantee.
expected revenue value ÷ sprint investmentThe probability-weighted revenue scenario divided by the fixed four-week sprint cost.
The model uses the standard four-week sprint. Gross meeting value is not CRM-stage pipeline, and expected revenue value is not a forecast or guarantee.
04 / Questions behind the numbers
Choose assumptions that match your sales process, include the complete operating cost, and compare more than one scenario.
Gross meeting value equals the qualified meetings entered for the sprint multiplied by your average contract value. It is not CRM-stage pipeline or a revenue forecast. The expected revenue value then applies the close rate you enter.
Use your historical meeting-to-closed-won rate when you have it. The 15% starting value is only an editable example, not a Coseek benchmark. If your data is limited, compare a conservative, expected, and strong case instead of treating one input as precise.
Sales cycle records the timing assumption behind the scenario. It does not change the gross meeting value or expected revenue value, predict the first close, or assume every opportunity progresses at the same speed.
A qualified meeting matches the agreed account and role criteria, captures the agreed problem, current process, timing, use case, or equivalent evidence, confirms the purpose of the next step, and has a specific attendee, date, time, and sent calendar invite.
This calculator models Coseek's standard four-week validation sprint. A fixed cost keeps the decision focused on the market, meeting scenario and downstream economics instead of letting an editable price input hide the actual offer being evaluated.
A sprint should be judged on market evidence as well as meeting volume. The calls should show whether buyers are reachable, how they respond to the problem and offer, what qualification looks like in live conversations, and whether the motion should scale, change or stop.
No. This is a planning model based on the inputs you choose. Actual results depend on market fit, buyer reachability, qualification, sales execution, prospect response, and the time required for opportunities to progress through your sales cycle.
Your market, your assumptions
