My name is Marc Bax. I founded Panchromos in 2004 to work directly with clients on the development of  technology-enabled products. I take a hands-on, system-level approach, focused on getting complex designs to work in both concept and practice.

Rather than supplying effort in a single discipline, I take responsibility for how a system comes together across electronics, mechanics, software and related physics domains such as sensing, optics or fluidics. This avoids the coordination overhead and late surprises that often arise when specialists optimise individual parts in isolation.

Technical  leadership and ownership

I lead the technical work on each project and carry out much of the engineering myself, taking responsibility for system-level decisions from early concept through to implementation and validation. This ensures that technical intent is preserved as designs evolve, and that trade-offs are resolved with full visibility of the system as a whole.

Rather than assembling a fixed team and fitting projects around it, I shape the team around the problem at hand. Where additional expertise or capacity is needed, I bring in a small number of trusted specialists for clearly defined contributions, while remaining the primary point of responsibility.

This approach combines broad, system-level thinking with deep single-discipline expertise where it matters, without the overhead, fragmentation or loss of context that often comes with larger delivery structures.

I often work alongside internal engineering teams, manufacturing partners or regulatory consultants. In these cases, my role is to provide system-level design leadership and integration, not to replace in-house capability.

A fully equipped studio

I work from my home studio, which comprises separate office, lab and workshop spaces, set up specifically for system development and experimentation. It provides dedicated electronics and fine mechanics work areas, diverse machinery for practical prototyping, and instrumentation  for measurement and testing.

Having these extensive facilities in-house allows me to move quickly between analysis, design and experimentation, and to resolve questions through evidence rather than assumption.

Practical outputs

Projects are structured around clearly defined deliverables, agreed with the client at the outset of each phase. These are chosen to represent meaningful progress and to support informed decisions about the next steps.

A key difference in how I work is that design outputs are typically validated in practice, not just on paper. System representations and CAD models are paired with physical mock-ups or prototypes; electronic designs are supported by built hardware and test results; analytical work is checked against experimental evidence where feasible. This is where my studio setup matters.

This approach reduces the gap between design intent and real-world behaviour, and gives clients greater confidence that outputs will stand up beyond the development environment.

So what?

For clients, this way of working typically results in:

• Faster convergence on viable system architectures
  Key trade-offs are addressed early, reducing rework and late-stage surprises
• Clear technical ownership and communication lines
  Responsibility is explicit, decisions are traceable, and coordination overhead is reduced
• Access to broader expertise without the overhead of a large team
  Additional specialists are brought in when needed, without fragmenting responsibility
• Faster learning through tangible evidence
  Decisions are informed by models, prototypes and test results, not just plans or assumptions
• A development setup geared towards making things real
  Ideas are explored and validated through hands-on work rather than remaining theoretical

If it’s not obvious whether Panchromos may be a good fit, an initial conversation is usually enough to find out.
