Decide build vs buy for outbound: in-house SDRs or a partner
Puts real numbers on the decision founders usually make on vibes: a fully-loaded 12-month cost model comparing in-house SDRs, an outbound partner, and hybrid — including management time, ramp, and turnover that salary-only comparisons hide — plus a fit assessment, per-path failure modes, and the due-diligence questions that expose meeting mills.
You are an advisor who has sat on both sides of the build-versus-buy outbound decision: you've built in-house SDR teams and engaged external partners, and watched both paths fail predictably. In-house fails when founders underestimate true cost — never just salary, but management attention, tooling, ramp time, and 40-50% SDR turnover. Partners fail when bought as a meeting vending machine with no internal owner and no feedback loop. You have no horse in this race; your job is honest math. Run my build-versus-buy analysis: 1. Fully-loaded cost model, 12 months, side by side: in-house (salary, benefits, tools and data stack, management time priced at my hourly value, recruiting cost, ramp months at partial productivity, and a realistic turnover scenario) versus partner (fees, my internal time to manage the relationship, onboarding period) versus a hybrid. Show cost per meeting under conservative, expected, and optimistic performance for each. 2. Fit assessment: score my situation on the factors that actually predict which path works — can someone here manage and coach SDRs, is my messaging proven, how fast do I need signal, how complex is the pitch, and where institutional knowledge lands in each path. 3. Risk profile per path: the top three failure modes for each and which I'm most exposed to. 4. Recommendation: one path, with the conditions that should trigger revisiting it, and the first three steps. 5. If partner: the 8 due-diligence questions that separate real operators from meeting mills — including questions about who owns the infrastructure, data, and learnings when we part ways. Avoid: pretending one answer fits everyone, comparing partner fees against SDR salary alone, and ignoring the option value of learning outbound internally. Before you write anything, interview me. Ask me these questions ONE AT A TIME, waiting for my answer each time: 1. What's your current outbound situation — anyone doing it today, and with what results? 2. What's your deal size, sales cycle, and is your outbound messaging proven or hypothesis? 3. Who would manage an SDR internally, and have they done it before? 4. What's your budget range, and how fast do you need pipeline signal? 5. What matters more in 18 months: owning the capability in-house, or maximum meetings per dollar? Once you have my answers, run the analysis. If my messaging is still unproven, weight that heavily — and say why it changes the answer.
How to use it
- 1
Copy the prompt into Claude, ChatGPT, or any LLM.
- 2
Price your own management time honestly in the interview — it's the cost founders zero out and regret.
- 3
Answer question 2 with evidence: 'proven messaging' means documented reply and meeting rates, not confidence.
- 4
Stress-test the recommendation by asking the model to argue the opposite path before you commit.
- 5
If you go the partner route, use the due-diligence questions verbatim on at least three candidates.
Best practices
Unproven messaging favors whichever path iterates fastest — clarify that before comparing costs.
A first SDR hire without an experienced manager fails more often than any other configuration; weight question 3 accordingly.
Whatever path you choose, insist on owning the domains, mailboxes, data, and learnings — portability is leverage.
Revisit the decision at 6 months with actual cost-per-meeting data; the right answer changes as you scale.
Example: what this looks like in practice
A founder of a 25-person insurance-tech company with $28K ACV debates hiring two SDRs versus engaging an outbound partner at $6K a month. He answers the interview: messaging is half-proven (one campaign at 1.5% reply), nobody internal has managed SDRs, and he needs pipeline signal within a quarter. The model's cost table shows in-house at roughly $210K year one fully loaded with a realistic mid-year turnover event, versus $84K for the partner — but flags the real differentiator as fit: no internal SDR manager plus unproven messaging makes the in-house path's failure mode (a floundering junior with no coach) highly likely. Recommendation: partner for 12 months with contractual ownership of domains and data, revisit at month 9, and hire in-house once messaging is validated and a sales manager exists.

Far more than the salary. A realistic fully-loaded number includes base and variable comp, benefits, the tool and data stack (sequencer, data providers, enrichment — often $500-1,000+ monthly per rep), recruiting costs, 3-4 months of ramp at partial productivity, and management time. For many companies the true first-year figure lands at 1.7-2x salary — before accounting for the sector's high turnover rates.

Build a quarterly outbound plan that survives contact with reality
Produces a complete quarterly outbound plan — pipeline math, prioritized segments, 3-5 concrete plays, a launch calendar, and named risks — grounded in your actual win rate and team capacity. The capacity check is the killer feature: it forces the plan to admit when the math doesn't close instead of papering over it with optimism.
Design an irresistible B2B offer with the value equation
Applies the value equation to your actual B2B offer instead of leaving it as a book concept. You get a blunt scoring of your current offer, three rebuilt variants with guarantees your margins can survive, the operational cost of each, and a small validation test — turning 'our offer is fine' into an engineering exercise.
Build a 13-week outbound campaign calendar for the quarter
Turns a pile of campaign ideas into a staggered 13-week execution calendar with owners, prep time scheduled before launches, standing review rhythms, and kill criteria at week 7. It prevents the classic quarter shape — frantic week-1 launches, silent middle, panicked final push — by design rather than discipline.
