Three ways to staff outbound and the systems behind it. Who should choose each one, the nine questions that decide it, and where each option honestly wins.
By Rees Bayba ·
TL;DR
Should you staff outbound with a fractional GTM team, an outbound agency or an in-house hire? Choose an in-house hire if you have a RevOps or GTM engineering leader who can direct the work and you can wait for a search and ramp. Choose an outbound agency if you only want meetings booked and do not want to own a system. Choose a fractional GTM team if you have no GTM engineer and need the data, signals and outbound system built and run now, by people who have built it before.
| Question | Fractional GTM teamAstra GTM | Outbound agency | In-house hire |
|---|---|---|---|
| Who builds and runs itSource: how a fractional GTM team engages | Wins on this row. A GTM engineer who builds and a campaign strategist who runs the motion, assigned to your account for the whole engagement. | The agency's team runs lists, copy and sending on its own process. | Your hire builds and runs it, often one person covering every layer alone. |
| Time to first live campaignSource: Astra GTM vs hiring a GTM engineerSource: agency vs in-house SDR | Work starts on your backlog in the first weeks, because enrichment, verification and campaign QA tooling already exist. | Fast. An existing team and stack start on your account. | Slowest. Search, offer and ramp all come before systems ship. |
| Who owns the system and data afterSource: how a fractional GTM team engages | For teams with no GTM engineer. Built in your stack, it is yours. Run on our infrastructure, the copy, lists and data are yours and the infrastructure stays ours. | Varies by contract. Get what you keep in writing before you sign. | Yours. Systems, prompts and data stay in house. |
| Cost shapeSource: BLS Employer Costs for Employee CompensationSource: GTME Pulse salary surveySource: build or buy outbound | A retainer scoped per engagement, with a three-month minimum. | A retainer, a per-meeting or per-lead fee, or a smaller base plus a performance fee. | Salary, plus benefits and payroll costs, plus tools, data and recruiting. |
| Depth of strategy and GTM engineeringSource: how a fractional GTM team engagesSource: Astra GTM vs hiring a GTM engineer | Wins on this row. Strategy, data, signals, deliverability and CRM architecture from one team that has built each before. | Built around campaign execution. Systems and strategy are lighter. | Depends on the hire. One person is usually strong in one or two layers and thin elsewhere. |
| Control over messaging and day to daySource: how a fractional GTM team engagesSource: agency vs in-house SDR | Shared. Nothing sends without your review, and the team runs the day to day. | Lower. The agency runs its own process and cadence. | Wins on this row. Full. They sit on your team and follow your priorities. |
| Scaling up or downSource: Astra GTM vs hiring a GTM engineerSource: what an outbound agency costs | Capacity can be re-pointed as priorities change, with a three-month minimum. | Set by the contract. Many sell units such as emails, prospects or meetings that you add or cut. | Hardest. Growing means another search, and shrinking means a departure. |
| Institutional knowledge kept in houseSource: agency vs in-house SDRSource: Astra GTM vs hiring a GTM engineer | Systems built in your stack stay there, but the people who know them sit outside your team. | Mostly stays with the agency. | Wins on this row. Stays on your team for as long as the hire does. |
| Fit with an existing RevOps or GTM engineering leaderSource: agency vs in-house SDRSource: Astra GTM vs hiring a GTM engineer | Works alongside them and adds build capacity around their roadmap. | Feeds their pipeline but sits outside their systems. | Wins on this row. Strongest. Your leader hires, directs and develops the person. |
| Best for | Teams with no GTM engineer that want the system built and run now, by people who have built it before. | Buyers who only want meetings booked and do not want to own or manage a system. The simplest of the three. | Teams with a RevOps or GTM engineering leader ready to direct a full-time hire and wait for the ramp. |
Read the marked cells honestly. An in-house hire wins on control, on knowledge that stays in the building and on fit with an existing RevOps or GTM engineering leader. An outbound agency is the simplest buy when meetings are the only thing you want. A fractional GTM team wins on who builds it and on depth of GTM engineering, for teams that do not have a GTM engineer. Ownership is not a contest: what Astra builds in your stack is yours, and when work runs on our infrastructure, the copy, lists and data are yours while the infrastructure stays ours. Both are normal, and the contract should say which applies.
An in-house hire costs more than the salary. The Bureau of Labor Statistics puts wages at 68.5% of total employer cost for full-time private-industry workers, so benefits and payroll costs add the rest, before tools, data, recruiting and the months of ramp. For the salary line itself, use GTME Pulse's survey of GTM engineer pay by seniority, location and company stage.
Outbound agencies bill four ways: a monthly retainer for an agreed scope, a fee per meeting, a fee per lead, or a smaller base plus a per-meeting or performance fee. Compare them on everything you pay in a month divided by held meetings that match a written definition. Astra GTM does not publish a rate card. Engagements are scoped per engagement with a three-month minimum, and most run past twelve months.
Often the best answer is two of the three in sequence. A fractional team builds the data, signal and outbound system and runs it while you hire, and the hire inherits a working motion. Clipper Defense started with zero outbound and averaged 23 ICP-fit meetings a month once that system was running. The full story, with context, is on the Clipper Defense case study.
An outbound agency sells meetings and runs lists, copy and sending on its own process. A fractional GTM team builds and runs the system behind pipeline: data, signals, deliverability, CRM architecture and campaigns. At Astra GTM that is a GTM engineer and a campaign strategist assigned to your account, working in your stack or ours.
When you only want meetings booked and do not want to own or manage a system. If your ICP and offer already convert and you are happy for the agency to own the process and tooling, an agency is the simplest of the three options.
When you already have a RevOps or GTM engineering leader who can direct the hire, outbound is a permanent core channel, and you can wait for a search and ramp. An in-house hire gives you the most control and keeps the knowledge on your team.
It depends on scope, so compare cost shape rather than the invoice line. A hire costs salary plus benefits and payroll costs (the Bureau of Labor Statistics puts wages at 68.5% of total employer cost for full-time private-industry workers), plus tools, data, recruiting and ramp. Astra GTM does not publish a rate card; engagements are scoped per engagement with a three-month minimum.
With Astra GTM, what we build in your stack is yours. When work runs on our infrastructure, the copy, lists and data we produce for you are yours and come back to you, and the sending infrastructure and tooling stay ours. Ask every partner, agency or not, to put this in the contract.
Yes, and it is a common pattern. The fractional team builds and runs the system during the search and ramp, and the hire inherits a working motion. A fractional team also works alongside an existing RevOps or GTM engineering leader by adding build capacity.
Astra GTM is a fractional GTM team based in Austin, Texas, working with B2B startups and mid-market revenue teams. Engagements have a three-month minimum and most run past twelve months.
