Yes, perhaps it's a decent algorithm for finding near-optimal solutions to the traveling salesman problem, but the quantum computing thing seems to be mostly marketing.  Emulating quantum computing on non-quantum hardware sounds like... just normal computing.

It does not take any special expertise to make that judgement. (not kidding)
If it can run on regular HW it is just another algorithm with all the rules that apply.

The portrait of a CEO does not support the credibility either.

If anything is dubious here it is D-Wave's claims. I've heard a lot of people claim that their machine isn't a proper quantum computer and cannot perform the same kinds of operations. I also remember prior claims that the, at the time, state of the art D-Wave machine had worse performance than a well coded software implementation. But I don't know how fast their current hardware is versus a software implementation.

The algorithm has already been proven by ServicePower's customers. It was first used back in 2012 for an academic problem: "Quantum annealing is a combinatorial optimization technique inspired by quantum mechanics. Here we show that a spin model for the k-coloring of large dense random graphs can be field tuned so that its acceptance ratio diverges during Monte Carlo quantum annealing, until a ground state is reached. We also find that simulations exhibiting such a diverging acceptance ratio are generally more effective than those tuned to the more conventional pattern of a declining and/or stagnating acceptance ratio. This observation facilitates the discovery of solutions to several well-known benchmark k-coloring instances, some of which have been open for almost two decades." https://e-space.mmu.ac.uk/618085/

This is not my field, but I'm getting vibes of dubiousness.
