What Heyday does
Heyday is described as an AI copilot for research, notes, and conversations, positioning the company in the personal knowledge-management and AI assistant category that competes with tools such as Notion AI, Mem, and Reflect. The product concept centers on helping individual users capture, organize, and interact with information across research and conversational workflows, though the source data provides no detail on the underlying technical architecture, model stack, integrations, or feature set. The company was founded in 2021 and is headquartered in San Francisco, with a listed team size of 1-10 employees, indicating an early-stage operating profile.
The business model is not disclosed in the available inputs. There is no public pricing information, no customer logos, no segment detail, and no documented go-to-market motion. The company has raised approximately $6.5M in disclosed priced capital through a 2022 round led by Spark Capital, with participation from Abstract, Alumni Ventures, Correlation Ventures, FirsthandVC, Ride Ventures, and Spacecadet Ventures. Two additional funding entries are recorded with $0 reported amounts: a 2021 round involving Bossa Invest and Unpopular Ventures, and a 2024-05-24 entry attributed to Salesforce Ventures, which suggests possible enterprise distribution intent or ecosystem alignment. Samuel DeBrule is listed as co-founder.
A material caveat: the corporate website at heyday.xyz is currently parked with GoDaddy rather than hosting an active product or marketing site. This signal, combined with the small headcount and absence of any disclosed revenue, pricing, or customer references, indicates the company may be inactive, in a transitional state, or operating at very low scale. The available data does not support a confident assessment of current operations, customer traction, or forward momentum.
