Two founders want to stop renting their marketing. One wants to run it herself within six months. The other wants a team that's his, but led by someone more experienced than him. They need different models. Here's how to tell which one is yours.
Both BOT and BOM build a marketing team inside your company, on your payroll, with your accounts and data. In Build-Operate-Transfer, we run a 90-day pilot and then hand the team over to your leadership. In Build-Operate-Manage, we stay on as your fractional CMO, leading and managing your team. Choose BOT if someone in your business can lead marketing; choose BOM if you need senior leadership you don't yet have.
- BOT: we design, hire and train your team, run a 90-day pilot, then transfer it. Typically 3 to 6 months.
- BOM: the team is yours, and we stay as the management layer and fractional CMO, with OKRs, weekly reviews and training.
- The deciding question is usually leadership: is there someone in your business who can run marketing after handover?
- In both models the team is on your payroll and accounts, data and playbooks are yours.
- 82% of large US advertisers now run in-house teams, and the top concern is keeping that talent energised.
What's the difference between BOT and BOM?
Ad Asthra works through two main models. Both start the same way: we audit your marketing, design the team you need and build it inside your company, with people on your payroll, accounts in your name and processes written down. The difference is what happens once the system is running.
- Build-Operate-Transfer (BOT): we design your team structure, hire and train the people, run a 90-day pilot to set up the routines, KPIs and reporting, then transfer a working marketing engine to you. Your leadership runs it from then on. See how BOT works.
- Build-Operate-Manage (BOM): the team stays yours, but we stay on as the management layer, acting as your fractional CMO. We align the team's work to your business goals, run weekly reviews, keep the team trained and hold everyone to the numbers. See how BOM works.
BOM isn't an agency retainer. Agencies do the work themselves. In BOM, your own employees do the work, and we lead and manage them.
| BOT | BOM | |
|---|---|---|
| Whose payroll is the team on? | Yours, from day one | Yours |
| Who leads marketing long term? | Your own leadership, after the transfer | Ad Asthra, as your fractional CMO |
| Typical timeline | 3 to 6 months: 4 to 6 weeks of hiring, then a 90-day pilot | Ongoing, reviewed against agreed goals |
| Best when | You want full independence and someone in-house can lead | You have or want a team, but no senior marketing leader yet |
| How success is measured | A team that hits its KPIs without us | OKRs tied to revenue, efficiency and output |
| Who owns accounts, data, playbooks? | You | You |
Why the choice matters more now
Companies everywhere are rethinking who runs their marketing. Among large US advertisers, 82% now have in-house agencies, up from 42% in 2008, and 65% have moved some work from external agencies in-house in the past three years (ANA, 2023). Gartner found 39% of CMOs plan to cut agency budgets (Gartner, 2025), and labour's share of marketing budgets rose from 21.9% to 24.5% in a year (Gartner, June 2026). Businesses are spending more on their own people and less on rented capability.
But building a team is only half the job. Someone has to lead it. That's the real question behind BOT or BOM.
The 5 questions to ask
1. Do you want marketing to run without any outside help?
If your goal is full independence, a team that knows your business and is led from inside it, BOT is designed for that. We build it, prove it works, then step away.
If you'd rather have experienced leadership on call while your team does the work, BOM fits better. Many founders choose BOM first and move to full ownership later, when they hire their own marketing head.
2. Is there someone who can lead the team after handover?
This is often the deciding question. After a BOT transfer, someone in your business has to set priorities, review results and keep the team improving. It can be a founder for a while, or a marketing head you hire.
If nobody has the time or experience, a team without a leader drifts. That's the gap BOM fills: senior CMO-level guidance without the full-time cost. Our fractional CMO page explains what that role covers.
3. Can you support the team's salaries long term?
In both models, the team is hired onto your payroll, so plan for salaries, tools and training. The difference is the leadership cost. In BOT, you eventually carry a full-time marketing leader. In BOM, that leadership is shared and part-time. Our cost framework compares the numbers over three years.
4. How fast is your marketing likely to change?
If your channels, markets or products change often, a team needs constant learning. ANA research found the leading concern for companies running in-house teams was keeping talent energised, cited by 63% (we cover it in 82% of big advertisers now run in-house teams). BOM builds that upskilling in, with regular training on new tools, AI tactics and platform changes. With BOT, plan it into the handover.
5. How central is marketing to your growth?
If marketing is how you win customers, owning the capability fully is worth it: every campaign makes your own team smarter. If marketing supports a business that grows mainly through referrals, partnerships or a sales team, a managed model may be all you need.
A quick way to decide
| If this sounds like you... | Consider |
|---|---|
| "I want to own it fully, and I have or will hire someone to lead it." | BOT |
| "I have a team, but nobody senior is driving it." | BOM |
| "I want to own it eventually, but I don't have a leader yet." | BOM now, then hire your own head and transition |
| "I'm not sure what marketing team I even need." | Start with an audit; both models begin there |
| "I already have a mature team and just need an outside check." | Advisory & Governance |
Three founder scenarios
A multi-speciality clinic group in Hyderabad. The founder wants every centre to generate its own enquiries and has a capable operations head who can take over marketing reviews. BOT fits: build a team of three, run it through a 90-day pilot, then hand over.
A Bengaluru SaaS start-up with two marketers. The team is skilled but has no senior lead; the founder spends evenings reviewing campaigns. BOM fits: fractional CMO leadership with weekly reviews, OKRs and training, until the company is ready to hire its own head of marketing.
A real estate developer between launches. Each launch has meant a new agency and starting from zero. BOT builds an in-house launch team that carries learnings from one project to the next. See how we work with builders.
What both models have in common
Whichever you choose, a few things don't change:
- The team is hired onto your payroll.
- Ad accounts, analytics and data sit in your company's name from day one.
- Every process is documented, so the capability stays with you.
- Success is measured in business results, not activity.
That's the core difference from a traditional agency, and the reason we exist. The Why Ad Asthra page sets out the comparison in full.

Frequently asked questions
What is the difference between BOT and BOM?
In Build-Operate-Transfer, Ad Asthra builds your marketing team, runs it through a 90-day pilot, then transfers it to your leadership. In Build-Operate-Manage, the team is still yours, but Ad Asthra stays on as the management layer and fractional CMO.
Is BOM the same as hiring an agency?
No. An agency does the work with its own staff. In BOM, your own employees do the work, and Ad Asthra leads and manages them, setting goals, running reviews and training the team.
How long does a BOT engagement take?
Typically 3 to 6 months: around 4 to 6 weeks to hire, then a 90-day pilot to set up routines, KPIs and reporting before the transfer.
Whose payroll is the team on?
Yours, in both models. The team is hired directly onto your payroll from day one, so the people who learn your business stay in your business.
Which is better for a start-up?
It depends on leadership. If a founder or senior hire can lead marketing after handover, BOT gives full independence. If nobody has that bandwidth yet, BOM gives you senior leadership part-time until you're ready to hire.
Can we switch from BOM to BOT later?
Yes. A common path is BOM first, with fractional CMO leadership, then hiring your own marketing head and moving to full ownership. Because accounts, data and playbooks are already yours, the transition is straightforward.
What if a hire doesn't work out?
In BOT, Ad Asthra offers a replacement guarantee: if a candidate doesn't meet their KPIs within the first 60 days, we replace them at no extra cost.
