NSG is a senior-led growth and analytics practice serving fintech, e-commerce, and consumer brands across the US, EMEA, and MENA. We embed with your team, build the data and ML infrastructure your growth depends on, and deploy AI where it actually moves revenue.
Founder-led from New York City. Columbia · Google Cloud · Microsoft AI. Trusted by operators in e-commerce, fintech, and consumer growth.
What We Do
Most growth teams are flying blind because their data lives in five places and reconciles in none. We architect unified data pipelines that integrate e-commerce platforms, paid media, CRM, and product telemetry into a single source of truth. The result: every marketing dollar, every cohort, every channel — measured cleanly.
Reporting tells you what happened. Models tell you what to do next. We build production-grade machine learning systems for audience segmentation, churn prediction, propensity scoring, and revenue forecasting — applied through rigorous A/B testing and statistical validation.
Generative AI has changed what a growth team can produce in a week. We deploy AI across creative testing, content personalization, lifecycle automation, and conversion rate optimization — translating model outputs into measurable lift on customer acquisition and lifetime value.
How We Work
We work as an extension of your team — not a vendor on a SOW. Every engagement is led by senior practitioners who have built and run growth at venture-backed companies. No outsourced execution, no junior managed accounts.
Audit data, attribution, and the growth math. Find what's actually broken.
Stand up the pipelines, dashboards, and measurement infrastructure to make decisions on real numbers.
Build the predictive layer — segmentation, propensity, forecasting — that turns data into decisions.
Move models into production, test continuously, and compound the wins.
Industries
Payments, lending, neobanks, and wealth platforms. We understand the regulatory constraints, the LTV math, and the compliance posture that fintech growth requires.
DTC, marketplaces, and omnichannel retailers. From MMM to creative testing to subscription mechanics — we know the levers that actually move category growth.
Lifestyle, wellness, and digitally native brands scaling from $5M to $100M. We bring the data infrastructure most consumer teams don't have but desperately need.
Currently serving clients across the United States, Europe, and the MENA region.
