For most organisations, the honest answer is neither, on its own. Building alone is slow and carries real hiring risk; buying alone leaves you with no capability once the vendor leaves. The model that actually works is a third option most comparisons leave out: embed - external engineers who work inside your team, managed by someone else, so the capability stays with you when the engagement ends. ## The build option: hire and grow an in-house team Building in-house means recruiting AI engineers directly onto your payroll. The upside is real: the team is yours, the knowledge stays, and there's no vendor relationship to manage. The downside is time and risk. Good AI engineers are scarce and expensive to hire, ramp-up on your codebase and domain takes months, and a single AI hire is routinely asked to carry an entire strategy - evaluating tools, building agents, redesigning workflows and training colleagues at once, which is [an impossible brief for one person](https://www.andabove.com/feed/hiring-an-ai-engineer-isnt-your-ai-strategy.md). Building works best when you already know what to build and just need more hands on it. ## The buy option: hand the problem to an agency Buying means engaging an agency or consultancy to scope, build and hand over a solution. The upside is speed and access to people who've solved similar problems elsewhere. The downside is the handoff. A consulting team delivers a roadmap or a finished build, an internal team inherits it, and the organisation is often left unable to extend or maintain what was shipped without going back to the vendor. Buying works well for a bounded, well-defined piece of work with a clear handover point - it works less well when the goal is a standing internal capability. ## The option most comparisons skip: embed Embedding means external engineers work inside your team, day to day, on your codebase and your workflows, managed by the partner rather than by you. It removes the handoff risk of buying (there's no handover moment, because the people who build it are already working alongside your team) and the hiring risk of building (you're not recruiting, managing performance, or carrying the cost if a hire doesn't work out). It is, in effect, buy and build at once: you get the in-house delivery you wanted, without the recruitment load, and the capability transfers to your people as the work ships. This is the model behind [an embedded squad of ten running inside Tesco for two and a half years](https://www.andabove.com/work/tesco/retail-media-from-weeks-to-live-in-days.md), taking retail-ad creative approvals from four weeks to days. It's also how [an AI-powered property valuation platform shipped for Upstix in seven days](https://www.andabove.com/work/upstix/building-a-scalable-app-to-transform-selling-homes.md) - a technical path too unproven for an internal team to have derisked alone, delivered at a pace no external handover model could match. ## Two tiers of embed, depending on what's missing Embedding isn't one shape. We run it in two tiers. The first is [forward-deployed engineers](https://www.andabove.com/services.md): senior engineers embedded directly in your team when the gap is technical - you know roughly what needs building and need capacity or specific expertise to build it. The second is an AI product squad: the same embedded engineers plus product management and design, for when the gap is broader than engineering - when the harder question is what to build and for whom, not just how. [We built the agent system now supporting 5,000 Google Cloud sellers](https://www.andabove.com/work/google/scaling-googles-salesforce-with-custom-solutions.md) this way, from concept to production in 90 days. Because we don't sell a platform, an embedded squad has no reason to optimise for which model you end up locked into - the architecture gets built around your constraints, not a vendor's roadmap. That's the same independence argument [we've made about forward-deployed engineering generally](https://www.andabove.com/feed/forward-deployed-engineers-alone-wont-fix-ai-adoption.md): the model only pays off if what's left behind is capability, not just a shipped workflow. ## How to actually decide Start from what's genuinely missing, not from a default preference for owning everything. If the constraint is throughput and the technical path is already clear, hiring in-house is often the right call. If the technical path is unproven, or the team doesn't have anyone who's solved this class of problem before, an embedded squad gets you there faster and de-risked, without leaving you dependent on the vendor forever. Most organisations that get this right end up doing both over time: internal engineers own the system long-term, while embedded squads open up new ground the internal team hasn't tackled yet. For a fuller walk-through of how to weigh a large consultancy against an embedded specialist squad against in-house build, see [how to choose an AI consultancy](https://www.andabove.com/feed/how-to-choose-an-ai-consultancy.md). We also unpack this build/buy/embed framing in more depth in [our webinar on the AI decision](https://www.andabove.com/webinars/build-vs-buy.md). ## Frequently asked questions ### Should we hire an AI agency or build an in-house AI team? Neither is automatically right - it depends on whether your constraint is throughput (build) or judgement on an unproven technical path (buy or embed). Most organisations that get furthest do both over time, with an embedded squad opening up new ground and an internal team owning what's proven long-term. ### What does it mean to 'embed' an AI team instead of building or buying? It means external engineers - and, where the gap is broader than engineering, product and design too - work inside your team on your codebase and workflows, managed by the partner rather than recruited onto your payroll. You get the pace and expertise of an agency without the handoff, and the capability stays with your people as the work ships, rather than leaving when the vendor's engagement ends. ### Is embedding more expensive than hiring in-house? It avoids the costs hiring carries that don't show up on a rate card: recruitment time, ramp-up months before a new hire is productive, and the risk of a hire that doesn't work out. For a single well-scoped workflow or an unproven technical path, embedding is typically faster to value than recruiting, even before those hidden costs are counted. ### Can we switch from an embedded team to fully in-house later? Yes, and it's the point of the model done properly. Because the embedded team works inside your codebase and processes rather than a vendor's own systems, the capability transfers as the work ships. The two-and-a-half-year Tesco engagement is the model held over the long term rather than a one-off deployment; other engagements are structured to hand over sooner, once your team can run what's been built. ## Next up - [Should you hire an AI engineer?](https://www.andabove.com/feed/hiring-an-ai-engineer-isnt-your-ai-strategy.md) - [The fastest way to waste money on AI](https://www.andabove.com/feed/the-fastest-way-to-waste-money-on-ai.md) - [View our feed](https://www.andabove.com/feed.md) --- ## Footer ### Pages - [Home](https://www.andabove.com/index.md) - [Work](https://www.andabove.com/work.md) - [Services](https://www.andabove.com/services.md) ### Studio - [About](https://www.andabove.com/about.md) - [Careers](https://www.andabove.com/careers.md) - [Feed](https://www.andabove.com/feed.md) ### Legal - [Privacy](https://www.andabove.com/privacy-policy.md) - [T&C](https://www.andabove.com/terms.md) ### Our partners - Anthropic - Google Cloud Partner - Vercel - Webflow Certified Partner ### Recognition - [Top Clutch.co Artificial Intelligence Company England 2026](https://clutch.co/profile/above-1?utm_source=clutch_top_company_badge&utm_medium=image_embed&badge=127900) ### Contact [Contact](https://www.andabove.com/contact.md) 1st Floor, The Binary, 27 Copperfield St London, SE1 0EN © 2026 &above™
