A portfolio manager builds his own financial tools with Codex
A portfolio manager at Benefit Street Partners built a loan-valuation tracker with Codex in about 10–12 development hours, according to OpenAI. Here, the person doing the work also builds the software—a practical example of AI making bespoke tools accessible beyond software teams.
Anant Kumar previously needed someone with software expertise to build a dashboard and bring in the data. His tracker now compares how different holders value the same loan; the reported development time includes later additions and refinements.
A second tool produces a first-pass analysis of credit agreements, often 300 pages or longer, in about 20 minutes, followed by at least an hour of human review. Kumar says committee follow-ups that once took days or weeks can now be answered within a day, sometimes during the meeting.
BSP describes using this capacity for more thorough underwriting within existing deal timelines. Investment decisions remain with people.
