"We brought Summer in at Zerve when we needed content that could actually drive organic search, and the results were hard to argue with. Blog traffic grew over 500% year over year, with individual posts ranking and pulling real traffic within weeks of publishing. She ran a complete content operation for us, learned the product deeply, and produced at the level of a full team. If you're an early-stage B2B company that needs content to perform, she's the person to call."

She is organized, comes in with actionable ideas, and is a pleasure to work with. I give her our highest endorsement."

"Summer and I worked together for a year at the tech startup Zerve AI, and she is someone I could always rely on to get things done. She wrote a steady stream of blog and web content for us, helped manage the migration of our blog to a new system, and handled a lot of behind-the-scenes SEO details completely independently. Her high-quality work helped increase our visibility across search and AI platforms. On top of that, she brought thoughtful ideas to the table and was just a genuinely pleasant person to work with day-to-day. I would happily work with Summer again."
