1stdibs.com announced a leadership change alongside its third-quarter results. Chief Executive David Rosenblatt will become executive chair on Jan. 1, 2027, and Chief Product and Marketing Officer Bradford Shellhammer will take over as CEO. The results announcement covers the quarter ended Sept. 30, 2026, but the financial figures are not included in the material provided here.
Key details
- Transition date: Rosenblatt will leave the CEO and principal executive officer roles effective Jan. 1, 2027. He will remain on the board as executive chair and continue providing services to the company, but will no longer be an executive officer.
- New CEO: Shellhammer, 50, has been 1stdibs’ chief product and marketing officer since August 2025. His previous roles include product and marketing leadership at Rent the Runway, chief product officer at Reverb, and senior positions at eBay. He has also founded several companies.
- Board role: The company expects Shellhammer to join the board when he becomes CEO, by adding a new directorship. He will not receive additional compensation for board service.
- Pay package: Shellhammer’s new offer letter sets his annual base salary at $600,000 and makes him eligible for a target annual cash bonus of $600,000. It replaces his earlier employment offer letter.
- Equity awards: Subject to board approval after his promotion takes effect, Shellhammer is to receive an annual grant of 360,000 restricted stock units and a one-time promotion grant of 200,000 units. The annual award is scheduled to vest in quarterly installments over three years; the promotion award over five years. Vesting for both is scheduled to begin June 8, 2027, and depends on continued employment.
- Existing bonus repayment terms: The new offer letter continues repayment obligations tied to Shellhammer’s previously paid $200,000 signing bonus and $100,000 retention bonus. If he resigns or is terminated for cause within 24 months after his original employment start date, he must repay half of the signing bonus and all of the retention bonus.
The transition changes the company’s top operating role while keeping Rosenblatt on the board as executive chair. Shellhammer’s CEO appointment is paired with a substantial cash-compensation package and equity awards, with the equity grants still subject to board approval.
