Marta was very helpful and knowledgeable. She was well prepared for the meeting. With herself as a founder and a mom, she understands the issues well.

Marta is a very kind and helpful mentor. I work at a small company without a lot of internal marketing expertise or other colleagues to brainstorm ideas with. Having Marta as a resource to talk through my work has been a huge help!

Marta helped me think through how to develop a content strategy out of an existing customer communication project I'm working on. She was kind enough to share a tracking sheet that she's used in the past to PM the strategy, as well. Thanks Marta!

Marta and I talked SEO for my startups first big push into content. As Head of Growth I like to think I know something about content and yet Marta brought a fresh pair of eyes to the conversation that's, frankly, hard to qualify. It's been said "a fresh perspective is worth 40 IQ points".....truthfully, it's more like 100 IQ points. Thanks Marta!

Marta was friendly, her advice was beyond cliche, she had made notes in advance of things that needed my attention. She is knowledgable and knows what she talks. She had a debut on GM with my session, I wish her the very best in helping entrepreneurs!
