Aventus Consulting is a niche B2B knowledge-based consultancy that requires a different marketing approach to many other businesses. Siobhan’s experience in niche B2B marketing has been an invaluable asset to our company, with many of our clients commenting on how professional our marketing material is and that we punch above our weight with marketing. Siobhan also creates detailed technical drawings for the documents we prepare for government submissions. I recommend With Zest to any B2B business who is looking to improve how they market their business.
