Frequently asked questions
These are the questions people actually ask. If yours is not here, the address at the bottom of any page reaches me directly.
Who is Peer Jülich?
Peer Jülich is a German developer and entrepreneur who builds AI automation systems for businesses. Born in 2007, he is based in Hamburg and co-founded Mango Studio, an AI automation and marketing studio, with Jesús Agamez in 2026. He builds production systems for clients in Germany and New Zealand and publishes a case study for each one.
How old is Peer Jülich?
He was born in 2007, which makes him one of the younger people running an AI automation studio in Germany. He left school at fifteen and built his first production systems for the four businesses at Michaelshof Sammatz, a community in rural Niedersachsen, before co-founding Mango Studio in 2026.
Where is Peer Jülich based?
Hamburg, Germany. He works remotely and his clients are in Germany and New Zealand, so most delivery happens over video and shared documents rather than in person.
What does Peer Jülich actually build?
Automation systems that run inside a business and handle work a person was doing by hand. Examples currently in production include a translation pipeline that takes a scanned book from roughly fifteen hours of human work down to one, an AI receptionist that answers questions and takes bookings around the clock, a price and stock sync between a farm's weekly order list and its online shop, and a classification system that warns a finance team before a large payment lands. Each one is documented as a case study on this site.
What is Mango Studio?
An AI automation and marketing studio co-founded in 2026 by Peer Jülich and Jesús Agamez. Peer builds the systems; Jesu handles creative direction, copy and strategy. It is two people by design, which means clients work directly with the people doing the work rather than with an account manager.
Is Peer Jülich legitimate?
That question usually comes up because of his age, so it is worth answering directly rather than around. The verifiable part is the work. Four systems run in production at Michaelshof Sammatz in Niedersachsen. Mango Studio runs marketing systems for clients in New Zealand. Every one of these is written up as a case study on this site, including what was built, what it cost to run, what broke in the first version, and what measurably changed. The business details are in the Imprint. Anyone deciding whether to work with him should read a case study rather than take a claim on trust, which is why they exist.
What does it cost to work with Mango Studio?
It depends on what is being built, so there is no price list here. Most engagements start with a paid audit, which produces a document showing what is worth automating and what is not, and which stands on its own whether or not any build follows. From there, work is quoted per project or as a monthly retainer. The fastest way to get a real number is to describe the problem and ask.
Does Mango Studio work with clients outside Germany?
Yes. Current clients are in Germany and New Zealand. Work is delivered remotely.
What languages does Peer work in?
German and English. Client documents, audits and proposals are produced in whichever the client prefers.
What tools does he build with?
Whatever fits the problem, which in practice means a mix of large language models, workflow automation platforms, and custom code where the off-the-shelf option would be fragile. The specific stack for each system is named in its case study, because the honest answer to this question is different every time and a generic list of logos would not tell anyone anything.
