About Perfios

**Perfios — company profile** Perfios Software Solutions Private Limited (CIN U72200KA2008PTC046602) is a Bengaluru-headquartered B2B fintech software company founded in 2008 by V. R. Govindarajan and Debasish Chakraborty, who set out to transform financial decision-making through technology. Debasish Chakraborty serves as Co-Founder and CTO. The company launched its first product, Perfios Finance Manager, in 2009, and its first B2B product, the Bank Statement Analyser, in 2012 — the product category that established its position in Indian lending infrastructure. Perfios describes itself as India's largest SaaS-based B2B fintech software company, and states it empowers 1,000+ financial institutions to make informed decisions in real time. Its platform specialises in real-time credit decisioning, analytics, digital onboarding automation, underwriting, risk and fraud assessment, due diligence and ongoing monitoring. The core of the business is aggregating and analysing financial data — bank statements, GST records, ITR data and other financial documents — and converting unstructured financial data into structured, decision-ready intelligence that banks, NBFCs and digital lenders use to underwrite loans faster. Customers are financial institutions rather than consumers, making Perfios a piece of infrastructure sitting behind much of Indian digital lending. On funding and valuation, Perfios has raised approximately $435 million from investors including Bessemer Venture Partners, Warburg Pincus and Ontario Teachers' Pension Plan (Teachers' Venture Growth), with a reported valuation of around Rs 10,000 crore. Perfios became a unicorn in 2024, sixteen years after its founding, and was the first of the Indian companies to enter the 2024 unicorn cohort. On culture and people practices, the company runs an interactive e-learning platform called Perfios University for training and learning modules, and operates rewards and recognition programmes for employees throughout the year. Perfios recruits across engineering, product, data and business functions, primarily in Bengaluru, with some roles offered remote or on-site. **Industry:** Fintech / B2B SaaS **Headquarters:** Bengaluru, Karnataka, India **Official website:** https://perfios.ai **Why work here as a fresher** Perfios is the kind of company where early-career talent is given real scope rather than busywork. Interns and freshers are placed on live problems, paired with experienced mentors, and reviewed on the same quality bar as everyone else. That combination — real ownership plus real feedback — is what turns a first role into a genuine career head start. **Culture** Expect a fast-paced, outcome-oriented environment with flat communication, short feedback loops and a strong bias for action. Teams are small enough that your contribution is visible and large enough that you learn from people who have already solved the problem you are facing. Learning, curiosity and honest debate are valued over hierarchy. **Growth & hiring** Perfios hires internships across engineering, data, product, design, marketing, finance and operations, and a meaningful share of its early-career hires convert to full-time offers. All openings are published on the company's official careers page, and applications for this role are submitted directly to Perfios there — no middlemen, no aggregators.
