Jeff Lewis is the founder and CEO of Guidebook. Prior to Guidebook, Jeff was Director of Sales for Criteo, where he was the first US hire and grew the team to 40 people and the business to 10M+ in annual revenue.
Jeff was a pleasure to work with while at Criteo. He brought an exceptional balance of salesmanship, technical expertise, and domain knowledge which gave us a high comfort level with both him and his team. I fully expect Jeff to be very successful in his future endeavors.
Jeff is a quick, smart and talented guy. He combines solid sales skills with good business instincts. I enjoyed working with him and look forward to hearing about his future successes.
Jeff has a dynamic personality and a passion for business. After communicating with Jeff on several occasions it became evident that he possesses the skills to match products and services to business objectives. Jeff always demonstrated the ability to partner in vision casting for business goals and offering recommendations on how to achieve them. I look forward to partnering with Jeff in the future.
I highly recommend Jeff Lewis since he is extremely smart, a very hard worker, and a top producing sales professional. Jeff closed our top advertiser as well as a few more in the top 10 while at Criteo and our US office was able to surpass our goals thanks to him. In addition to being a great colleague, Jeff was a leader and team builder outside of the office by organizing a fun company basketball league.
Jeff Lewis spear headed the advertising launch of Criteo in the US. As the first sales person hired, he had the amazing challenge to navigate a difficult landscape and build relationships quickly that could scale the product. He did just that by negotiating, closing, and integrating multiple top 25 online retailers that helped build the foundation for Criteo US. Jeff brings an entrepreneurial spirit, team dedication, and strategic thought to the office every day.
I enjoyed working with Jeff and highly recommend him. As a sales manager, Jeff can be push the sale without being too aggressive. Additionally, he seems comfortable with both the interpersonal and analytical aspects of the partnership. This allowed us to implement new strategies and move the business ahead. Most importantly, I trust Jeff’s integrity and business ethics. While I am certain he always had the best interests of his company in mind, he also had a strong sense of the long-term and worked to ensure the expectations of all parties were met.
I hired Jeff as the first member of the Advertiser sales team at TrialPay to sell into the top 500 Internet retailers. He identified the right partnerships to pursue, and closed them. Within a year, Jeff had closed many of the company's largest revenue-generating accounts, including two of our most valuable partnerships. He was my top sales manager on the advertising sales side of our business. In addition to his strong individual performance, Jeff was a solid team player who was well-respected by everyone in the company. I highly recommend Jeff and would hire him again if the opportunity arises.
Jeff is one of the most conscientious salespeople I have ever had the pleasure of working with. He has a great business sense and is able to discern which sales opportunities have the highest revenue potential—and makes marketing requests accordingly. Jeff takes the time to understand the workflows of other teams and was a valuable asset to all departments at TrialPay. I would welcome the opportunity to work with Jeff again in the future.
Jeff can articulate and subsequently negotiate and setup complex business partnerships as well as anyone. He is a great business development professional, a real pleasure to work with and also has some serious pickup basketball skills. Regardless of what side of the table I am sitting on I look forward to being at the same table as Jeff.
