1stdibs.com is changing its leadership at the start of 2027. CEO David Rosenblatt will become executive chair of the board on Jan. 1, while Chief Product Officer and Chief Marketing Officer Bradford Shellhammer will take over as CEO.
The company also announced results for the third quarter ended Sept. 30, but the financial figures and operating details are not included in the material available here.
Key details
-
Leadership change takes effect Jan. 1, 2027. Rosenblatt will step down as CEO and principal executive officer but remain a director as executive chair, providing other services to the company. He will no longer be an executive officer.
-
Shellhammer will become CEO and join the board. He has led product and marketing at 1stdibs since August 2025. The company expects to add one board seat for him when he takes the CEO role. He will not receive additional compensation for board service.
-
Shellhammer’s background spans online marketplaces and product leadership. Before 1stdibs, he held senior roles at Rent the Runway, Reverb and eBay, including leading product and buyer-experience work. He has also founded three companies.
-
His new compensation package includes salary and a target cash bonus. Shellhammer’s initial annual base salary will be $600,000, and he will be eligible for an annual cash bonus targeted at $600,000 under the company’s executive bonus plan.
-
The package includes two proposed equity grants, subject to board approval. Shellhammer is slated to receive an annual grant of 360,000 restricted stock units and a one-time promotion grant of 200,000 units. The annual grant would vest in quarterly installments over three years; the promotion grant would vest quarterly over five years. Vesting for both is scheduled to begin June 8, 2027, and depends on continued employment.
-
Some earlier bonus repayment terms remain in place. If Shellhammer resigns or is terminated for cause within 24 months after his original employment start date, he must repay 50% of a previously paid $200,000 signing bonus and all of a previously paid $100,000 retention bonus.
Plain-English implications
The transition separates the CEO role from Rosenblatt’s ongoing board leadership, while Shellhammer is expected to take both the top operating role and a board seat. The new compensation terms add substantial cash and equity incentives, with the equity awards tied to continued service over several years.
