Sola Tech Stack

Payment processing platform for merchants and high-risk accounts

Financial Services Brooklyn, New York 51–200 employees Privately Held

Sola operates a merchant payment platform with a .NET and React stack on AWS, focused on credit card processing, POS systems, and high-risk merchant services. Current hiring is support-heavy (3 of 8 roles) with engineering and sales each at 1 role, signaling a company in operational scaling mode rather than product acceleration. The pain-point list—bank rejections, merchant account changes, integration friction—reveals a business grinding through merchant onboarding and retention challenges, not exploring new payment verticals.
