Good Fits
- HR professionals and hiring managers evaluating product manager or data analytics roles.
- Recruiters who need a fast read on product judgment, analytical fluency, and technical literacy.
- Operators or investors evaluating product direction across research tools, native apps, and privacy-minded services.
- Teams with a concrete product, market, data, or funding conversation.
What to Send
Role, mandate, or investment context
Product area, market, or data analytics scope
Timeline and next step
Company, fund, product page, brief, or job link
Email is best for detailed role, product, or investment context. LinkedIn is best for recruiting and hiring-manager introductions. GitHub is best when the conversation starts from a technical artifact.
Response
I usually answer considered role, hiring, and product messages within one or two days. For time-sensitive interview loops or calls, put the deadline in the subject line.
