Startup and founder journeys are unique. Our support and engagement is tailored to your needs.
High-level judgment, fundraising support, targeted introductions, and strategic counsel across GTM, partnerships, policy, and market positioning.
Best for founders who need leverage, judgment, and network access.
Embedded operating support across growth, product, partnerships, GTM systems, and special projects. Typically 1–4 days/week for 1–3 months.

Long-term collaboration with aligned incentives through equity, revenue share, advisory, or partnership structures.
Best for exceptional founders building in areas where we have deep conviction in AI, markets, and infrastructure.
We don't believe every company needs a full-time hire, a consulting firm, or a venture round. Sometimes the right answer is focused support at the right moment.
Let's talk →Most collaborations begin with a focused conversation. Start with a short intro call, a one-off expert session, or a structured sprint.
A quick chat to compare notes on what you're building and explore whether there is a fit. Five slots per week, first come first served.
Best for first conversations and exploring whether to work together.
Book intro call →Bring one specific question on GTM, positioning, fundraising, product, or operator strategy. You leave with a focused conversation and a written 1-page summary within 24 hours.
Best for founders who want a focused answer on a specific question.
Book Expert Hour →A focused 6-week engagement with 4 working sessions, Slack access throughout, and a written strategic recommendations doc at the end. For founders working through a high-stakes challenge.
Best for founders who need more than a single conversation but not yet an ongoing retainer.
Start the Sprint →Building products ourselves keeps us close to the same technical, distribution, and operational challenges our founders face.
