## Questions

### Who runs investment decisions at Milemark Capital?

The four founding partners — Sebastian Barriga, Adela Jamal, Sinan Aral, and Michael Lipton — appear to make investment decisions collectively. The firm does not list a separate investment committee or junior investment staff. Aral provides the core AI expertise as an MIT professor, while Barriga brings institutional private equity experience from Carlyle and Lipton offers serial entrepreneurship and go-to-market skills.

### How does Milemark Capital source proprietary deal flow?

Milemark's sourcing relies on deep institutional ties to MIT and Harvard. Aral is a chaired professor at MIT; the firm states its team is embedded in the square mile between the two universities. The partners serve as mentors for on-campus entrepreneurship programs and attend exclusive startup events on and around the campuses. This academic adjacency gives Milemark access to companies before they circulate widely to other venture firms.

### Does Milemark Capital participate in fund commitments or only direct deals?

Based on the firm's public disclosures, Milemark invests directly into early-stage companies. There is no indication the firm makes commitments to external venture funds as a limited partner. Sinan Aral separately co-founded Manifest Capital, a Series-A venture fund, but Milemark's own portfolio is built from direct equity positions alongside board or advisory roles.

### Where does the underlying capital come from?

Milemark has not publicly disclosed the source of its investment capital. The four founding partners bring varied professional backgrounds — private equity, investment banking, technology operations, and academia — but no single family wealth origin or anchor LP has been identified. The firm operates as an independent early-stage investment manager.
