About CommerceIQ

**CommerceIQ — company profile** CommerceIQ is an e-commerce software company headquartered in Palo Alto, California, with a large India engineering and operations centre in Bengaluru employing 150+ people. It was founded by Guru Hariharan, a former senior Amazon executive. The company's lineage runs through Boomerang Commerce, founded in 2012; in 2018 Boomerang began developing e-commerce solutions for consumer brands, later sold its retail business to Lowes, and rebranded around its remaining decision-management tools as CommerceIQ in 2019 — the company dates its ecommerce-solutions work from 2018. CommerceIQ specialises in what it calls Ecommerce Channel Optimization (ECO), applying machine learning, analytics and automation across supply chain, marketing and sales to help consumer brands succeed on Amazon and other retail channels. Its software helps brands sell on online marketplaces, manage inventory and make decisions using predictive analysis. More than 2,200 brands use the platform daily to maximise incremental sales, category market share and unit profitability through online retailers including Amazon, Walmart, Target and Instacart. In 2022 CommerceIQ closed a $115 million Series D round led by SoftBank Vision Fund 2, reaching unicorn status at a valuation of over $1 billion; total funding stands at approximately $195.5 million across four rounds. Investors include SoftBank Vision Fund 2 and Madrona Venture Group. Following the round the company announced plans for a wider India presence. CommerceIQ operates in the US, UK and India and promotes cross-regional collaboration and inclusion. Its careers messaging emphasises empowering talent to drive innovation in ecommerce technology. Its Greenhouse board currently carries roughly 25 open positions across Engineering, Data Science, Product Management, Sales/Account Management, Operations and Finance, with many roles based in Bengaluru, Karnataka, plus references to Chennai. **Industry:** SaaS / E-commerce Analytics **Headquarters:** Bengaluru, Karnataka, India **Official website:** https://www.commerceiq.ai/ **Why work here as a fresher** CommerceIQ 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** CommerceIQ 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 CommerceIQ there — no middlemen, no aggregators.
