CUSTOMER testimonials:


I engaged David Lieberstein to assist us in negotiating contracts with our overseas supplier, coordinate importation and customs details, logistics warehousing and marketing strategies in the early stages of our product launch for our new biodegradable Bios Urn products.

The level of professionalism, expertise and positive support to us has been invaluable. His consulting services saved us a tremendous amount of extra time, money and worries to seamlessly support us to successfully import and launch our product.

I highly recommend David to assist anyone bringing a new product to market.

Just My Face

I don't know what I'd do without David. I am the consummate entrepreneur. I have numerous product ideas, plans and schemes. David helps me focus, prioritize and is teaching me the 'ins and outs' of bringing my product to market!

I know one of my inventions is going to make it with his expertise and support!

My Sipsee: Consulted with the inventors to support the final details of production, packaging, marketing strategy. I continue to support them in marketing their unique Portable Bottle Stopper with carrying case to the housewares and gift markets.

Fogle's Tape Pro: Consulting the inventor, Bruce Fogle, on all aspects of marketing, web development, logistics and business strategies along with sourcing a lower cost factory for projected volume sales. The Tape Pro easily holds the painter's blue masking tape in your pocket, to keep from misplacing or losing it.

Laundranet: Initially acted as a licensing agent for the inventors, David and Terrie Knell, to license their Retractable Clothing Drying Rack. After realizing that the potential licensees were too busy to focus on developing their product, we worked together to get fully engineered plans, locate the best factory overseas and get a working prototype. I was asked to join their new business as an equity owner and we just launched the Laundranet at the International Housewares Show in March 2017.

The Pet Concierge: Worked on a 6 month consulting program to assist a successful local veterinary hospital in negotiating with an overseas supplier in Europe on pricing, minimums, packaging, logistics and customs to import the first container of the Bios Urn. 

KHS Imports project: A major producer/factory of tabletop and household linens in India contracted with me to design a full product line to market to independent and middle tier retailers. I reviewed portfolios from dozens of artists to choose unique design concepts to differentiate this new collection from the competition. We were able to design this product line with three new licensed artists, 12 design concepts and 150 products with samples produced in a professionally made booth at the major Atlanta gift show in less than 120 days! 

Wine Things Unlimited: I developed this company as the founder, sole owner and art director beginning with decorative pewter cast Bottle Stoppers. Over the years, I was able to establish 'added value' by securing licensing rights to designs of Betty Boop, Looney Tunes, Star Trek, Popeye, Cirque du Soleil along with unique artists such as Laurel Burch. We expanded into hand painted drinking glassware, ceramic serveware, Wine Charms and wine accessories peaking at over $5 Million/year. ​
