About me

Sebastian Kirsch. Founder of Meritong

Software, hardware, general management and China in one person. You will rarely find that combination a second time in the German-speaking market, and it is at the core of every audit.

01 / What sets this apart

Why Meritong and not another provider?

Expertise in hardware, firmware, China and AI

01 Hardware

From prototype to series production. I review every component for cost, dependencies and AI readiness.

02 Software

Software and firmware are a decisive factor today. That is why I review them from the full assessment upwards, provided your product contains software or firmware.

03 China

I speak fluent Mandarin and read original Chinese documentation. I hold the conversations with your suppliers in Mandarin and, where needed, in English, German or Spanish.

04 AI

Want to run AI on your hardware? I assess on technical grounds whether a component supports the planned AI application.

02 / Background

How does this combination come about?

From a machine learning degree to running a deep-tech start-up

Stage 01

Computer science degree with a focus on machine learning

Chinese alongside the degree, up to negotiation level. The two threads that run through every audit today start at the same point.

Stage 02

Freelance software developer and project lead

Software architecture as a craft. That is why the audit reads the code base and not only the bill of materials. During this time, leading Chinese development teams, first experience with Chinese suppliers of embedded hardware and six months working in China.

Stage 03

Move into hardware: Cerabyte

Cerabyte in Munich writes data with a laser into a ceramic nanolayer on glass — archival storage built to outlast millennia. Optics, lasers and semiconductors, first as head of software development and later of the entire engineering department. Products from prototype through to series production.

Stage 04

CTO, then Managing Director Technology at Cerabyte

From the first grant to a multi-million valuation, across several funding rounds. Externally the liaison to CERN openlab on an open format standard for the data carrier, with talks at the US Library of Congress and at several developer conferences in Silicon Valley.

05 / Client references

What do clients and referees say?

Client testimonials

When critical components could no longer be sourced through the usual channels, Sebastian opened up alternatives for us on the Asian market: fast, structured and on site. He not only found suppliers, he also checked them for integrity and the goods for authenticity. In the end we had a clear and dependable basis for our decision.

Dr. Achim OehlerSenior Director, Dream Chip Technologies GmbHGermany

Sebastian conducted a scalability audit of our systems and supply chain and helped us define a development and procurement roadmap aligned with our financial constraints. He identified a better-fit hardware component and supplier in China, projected to save tens of thousands of euros at scale, and supported the efficient integration into our software stack.

Tobias FinéCEO, Be-In GmbHGermany

Sebastian combines deep technical understanding with strong system-level thinking across software, hardware, and global supply chains. He consistently demonstrated excellent analytical skills and the ability to communicate complex topics clearly across engineering and executive teams.

Steve CampbellCTO (retired), Western DigitalUSA

Sebastian led the implementation of a cloud-based platform with integrated edge devices for our municipality. He coordinated across software, hardware, and stakeholder groups and successfully delivered a system that operates reliably at scale. His ability to translate complex technical requirements into practical solutions was particularly valuable.

07 / The next step

How do I start?

The first call is free.

Thirty minutes. Your situation, your product, your suppliers. At the end you have the potential check: how many alternative suppliers are worth considering, and what saving is realistically on the table.
