  • Exponent Financial

    Participated · Series A · May 2026

    Exponent provides an integrated platform combining capital, expense management, and AI-powered accounting tailored for multi-unit franchise operators. The company positions itself as the Financial Operating System for America’s franchise operators, serving businesses within the $921 billion U.S. franchise economy. Exponent was founded and seeded by Era. It offers lending products for franchise acquisition, buildout, and bridge financing and plans to expand with AI Accounting products slated for release at the end of the year. The recently completed $40M equity-and-credit Series A is intended to accelerate product releases and scale lending and finance operations. Management emphasizes bringing strategic financial oversight onshore and automating bookkeeping to support franchise customers.

  • Nitra

    Participated · Series B · Mar 2026

    Nitra embeds AI agents into core business functions—payments, procurement, inventory management, scheduling, and insurance verification—giving medical practices a single system to run their back office. Its financial suite includes a Visa-powered expense card, bill pay, patient payment processing, and AI-driven accounting, while its commerce marketplace connects users to thousands of biopharma and medical-supply products through partners like McKesson and Medline. Recently the company added a voice-AI patient management module that handles appointment scheduling and insurance eligibility checks. In 2025 the platform’s annualized revenue jumped from $4 million to more than $33 million on 740 percent growth, and it surpassed $1 billion in annualized processing volume across thousands of doctors in over 700 clinics. December 2025 saw a single-day record of roughly $9 million in purchases. Management expects to serve 3,000+ clinics, top $150 million in annualized revenue, and exceed $4 billion in processing volume during 2026. Founded in 2024 by CEO Tim Hwang and President Jonathan Chen, Nitra plans to expand headcount from about 50 to over 200 and roll out new AI modules for revenue-cycle management, patient marketing, payroll, and staffing.
