AI Development Company in Berlin
The best AI Development Company in Berlin, at the best available price.
Most of what gets sold here as AI development is a team of five with one person who has shipped, and a bill that reflects the other four. This is the opposite arrangement: the engineer who scopes it is the engineer who builds it, the price is fixed before anything starts, and you pay nothing until a checkpoint is delivered and you accept it.
Berlin is Germany's startup capital: venture-backed companies in fintech, e-commerce, mobility and consumer apps work in English, hire internationally and move faster than the rest of the German market. It is also the seat of the federal government, so a second, slower market of ministries, agencies and their contractors sits alongside the startups. Startups here buy on speed and founder trust, while public-sector buyers buy through formal tenders.
AI projects in Berlin lean towards customer-facing features: support agents in several languages, search over product catalogues and document workflows for digital health and fintech. Each one is built with evaluation, EU hosting and a clear handoff to a person.
What you get
- One senior engineer end to end: the person on your first call architects it, writes it and hands it over
- LLM features, retrieval over your own documents, agents that call real tools, and voice where it earns its place
- Deployed in your own cloud account in a regional data centre, or on your own hardware where residency demands it
- Fixed price and fixed scope agreed in writing before work starts, invoiced per accepted checkpoint
- Code and infrastructure in your repository and your accounts, written to make us replaceable on purpose
Nothing payable upfront. You hold every dollar until a checkpoint is delivered and accepted, and thirty days of defect correction is included. Final scope and price are settled on a call before any work begins.
Invoiced in USD or EUR, payable by Wise or bank transfer.

You speak to the engineer who does the work. No sales rep, no deck.
Who builds here
AI Product & MVP Development
The typical Berlin buyer is a funded founder with a small English-speaking team who needs a working product before the next round, and who can decide in a week rather than run a tender.
What Berlin companies build with us
Get it built at $0.
That is not a discount. It is when you pay. The work is split into checkpoints with acceptance criteria written down before anything starts, and each checkpoint is invoiced only after you have seen it and accepted it. No deposit.
- $0 to start
- You hold every dollar until a checkpoint is delivered and you accept it. No approval, no invoice.
- Fixed cost, unlimited features
- Or hire the team outright: one fixed monthly cost, unlimited feature development, any stack.
- The engineer takes your call
- The person on your first call is the one who architects and writes it. No account managers, no bench time.
A US agency quotes $50,000 to $150,000 for the same build and asks for 40 to 50% of it before a line is written. Account managers, project managers, sales commission and bench time. None of it appears in your product.
Three stages, nothing hidden.
Twenty-minute call
You talk to the engineer who will build it. We scope the problem, and if this is the wrong fit for you, you get told so on that call rather than three weeks into a proposal.
Fixed proposal in 48 hours
Fixed price, fixed timeline, defined deliverables, in writing. No hourly billing, no open-ended scope, and no change-request business model.
Checkpoints until it ships
Working software at each checkpoint, with acceptance criteria agreed before that checkpoint starts and an invoice only after you accept it. Direct access throughout, not a ticket queue.
What actually applies here.
Regulation and data
GDPR applies alongside Germany's Federal Data Protection Act (BDSG), and private companies in Berlin are supervised by the Berlin Commissioner for Data Protection and Freedom of Information. Where a company has a works council, any tool capable of monitoring employees' behaviour or performance needs its agreement under Section 87(1) no. 6 of the Works Constitution Act, which often includes AI assistants that log usage. Digital health apps seeking reimbursement go through the BfArM's DiGA process. Germany's NIS2 implementation act has applied since December 2025, and the federal AI market surveillance law of July 2026 makes the Bundesnetzagentur the main AI Act authority. The EU AI Act has been in force since August 2024: general-purpose model rules applied from August 2025 and transparency duties from August 2026, while the 2026 Digital Omnibus moved the main high-risk obligations to December 2027 for stand-alone systems such as hiring or credit scoring, and August 2028 for AI built into regulated products.
Contracting and payment
You contract with an individual consultant based in India. Invoices in EUR or USD, paid by Wise or bank transfer. Your accountant handles an overseas supplier in the usual way, and any documentation they need is provided before access is granted.
Working hours
Four or more hours of daily overlap across your morning, Central European time, with same-day replies on working days.
Can you work with a Berlin startup that operates in English?
Yes. All work, documentation and calls are in English, which suits most Berlin startup teams. If a German public body or corporate customer needs material for their procurement, the technical documentation is written so your team can translate or adapt it.
Will our data stay in the EU?
Yes. Deployments go into an EU region of your own cloud account, such as Frankfurt, or onto your own hardware. The model, serving layer and logs stay inside that boundary, and access is named, limited and removed at handover.
How do working hours line up with Berlin?
Four or more hours of daily overlap across your morning, Central European time, with same-day replies on working days. The work is remote from India, so there are no in-person meetings, but reviews and demos happen on calls in your morning.
Why would we use an overseas engineer rather than a local integrator?
Often you should use both. An integrator holding the prime contract and the local relationship, with a specialist doing the AI and data layer underneath, is a common and sensible structure here. What you should not do is pay integrator rates for engineering that one person is actually doing.
Can the system run entirely inside our own infrastructure?
Yes, and in this region that is frequently the requirement rather than the preference. Model serving on your own hardware or in your own cloud account in a regional data centre, with no outbound calls, up to fully air-gapped.
Who owns the code?
You do, entirely. It ships into your repository on your own cloud accounts, documented so your team or your next hire can carry it without us, and all our access is removed at handover with written confirmation.
