Frequently asked questions
How does Positive Sum source proprietary deal flow?
Positive Sum's sourcing model is not publicly described. Without named team members or visible institutional partnerships, its approach to deal origination and proprietary pipeline development remains unclear from an external standpoint.
Profile maintained by Altss using OSINT (open-source intelligence), regulatory filings, licensed data partners, and verified direct submissions. Read the methodology. Source record modified: . Public records carry source-specific dates where available. No population-wide measured refresh cadence or universal verification deadline is established here. Page modified, source captured, fact observed, entity verified and aggregate measured describe different events. Check the date attached to the relevant claim; a missing verification date means unknown. Stored source history does not establish a customer-facing historical-analysis interface. To correct this record or make a privacy request, send the page URL and your evidence to privacy@altss.com; corrections are free.
