Charles River Ventures has renewed its 13,576-square-foot lease at 1000 Winter St. in the Bay Colony Corporate Center in Waltham.

The early-stage venture capital firm occupies space on the building’s third floor, which serves as the company’s east coast headquarters.

"Charles River Ventures works with some of the top start-up companies in the world, advising them on market strategy and helping them grow," said Ron Friedman, senior vice president of Richards Barry Joyce & Partners, which represented the company. "We are pleased to have counseled them in their lease negotiations. Waltham is an excellent location for Charles River Ventures, as it places them close to many of the companies they work with."

Friedman and Jon Varholak, partner of RBJ&P, represented Charles River Ventures. The building’s landlord, Eastern Development, was represented by FHO Partners.

"Jon and Ron provided us with exceptional expertise in this market. They made the entire process run smoothly and we could not be happier with the outcome," said Jack Genest from Charles River Ventures.
