Company profile
researched Sep 2026CustomerGlu is a Bengaluru-based enterprise software company offering a low-code, interactive customer engagement and retention platform for consumer apps. The product provides a library of ready-made, game-like interactive templates — including scratch cards, spin-the-wheel reward programs, "collect the stamp" and challenge-style activity programs, cart discounts and product-discount recommendations — that brands embed in their own apps to drive users toward specific actions such as completing a purchase, booking a ride or exploring a catalogue.
The platform is delivered as SDKs for web, native iOS, Android, React Native and Flutter, with REST APIs available for unsupported platforms. A hosted dashboard is used to configure campaigns, view real-time analytics and retrieve API keys, while webhooks and callback schemas let customers' backend systems listen for reward and analytics events. Earlier positioning emphasized AI-driven offer optimization: tailoring discounts to customer behaviour and lifecycle stage against budget and margin constraints, incorporating external signals such as competitor pricing and seasonality, and recommending specific products, brands or categories.
The company frames its approach as an alternative to push-notification-driven marketing, arguing that notifications generate brand recall but few conversions, and instead building "action trigger loops" inside the product. Management has described an intended move beyond gamification toward broader customer experience and retention, including in-app stories, real-time data-aggregation-based triggers and a low-code builder that lets customers create their own templates.
Founding story
Prateek Gupta, who worked on game development while studying at Vellore Institute of Technology, was introduced through a common professor to Raman Shrivastava, a VIT senior who had built a mood-based food recommendation app in the US and found he could acquire users but not retain them. Sumant Subrahamanya (Sumant US), a mechanical engineer from SRM University, had built a stock prediction app and encountered the same retention problem. Prateek's initial contact with Raman came in 2016 around software scalability challenges at Marax, and Sumant joined to lead product; the trio came together in mid-2017. Their first approach was predicting user behaviour to forecast churn, but they found the work non-scalable because every client had its own datasets, and that predictions alone did not tell companies what to do to retain customers. Prateek has described the resulting shift using an analogy to the game Mario, applying the idea of guiding a player's moves toward a maximum score to guiding users toward conversion.
Business model
CustomerGlu sells a B2B software platform to consumer-facing companies, delivered through SDKs for web, iOS, Android, React Native and Flutter plus REST APIs, with a dashboard for campaign management, analytics and API key administration. The positioning is low-code: product managers and marketers can launch interactive retention campaigns from a library of plug-and-play templates without engineering involvement. Stated product plans at the time of the pre-seed round included a low-code builder, a marketplace of templates and a community of "GluExperts."
Revenue comes from customer contracts for the platform, including annual contracts; the company reported crossing an approximately $200,000 annual run rate in late 2021 on the back of signing annual deals.
Traction
Reported metrics as of December 2021: roughly $200,000 ARR, monthly run rate growth from about $3,000 in January 2021 to $20,000, 15 live customers and about 50 in the pipeline, with a nine-person team as of May 2021. Named customers include Purplle — which reported a 4x revenue uplift from its programmes — BookMyShow, Zalora and Nykaa. Customers were reported to have seen a 42% uplift in daily activities and about 10% uplift in conversions.
Latest developments
At the end of 2021 the company reported approximately $200,000 in annual run rate, up from about $3,000 in monthly run rate in January 2021 to $20,000 monthly, with 15 live customers and roughly 50 more in the pipeline. It had closed a $320,000 pre-seed round led by Better Capital, was part of the Techstars Bangalore 2021 cohort, and planned to launch a low-code builder, a template marketplace and a GluExperts community while relocating one founder to the United States to lead expansion there.
▸Full profile — market position, technology, go-to-market, geography, history, risks & controversies
Market position
CustomerGlu competes in the customer engagement and retention software category, positioned as a low-code, in-app engagement layer for mobile-first consumer businesses. Reported customers and prospects include Purplle, BookMyShow, Zalora and Nykaa, with early US proofs of concept at companies including Seated and Even Better Snacks. The company has framed its addressable opportunity around the more than one trillion transactions occurring on mobile devices and the roughly 10% average margin companies make on each transaction.
Management positions the product against two reference points. Flyy is described as not a direct competitor because its game-centric approach increases app opens without delivering meaningful engagement, whereas CustomerGlu aims at horizontal customer engagement through in-app nudges, stories, real-time triggers and a low-code template builder. US-based AirKit is described as the closest comparison in terms of product build, but focused largely on contact-center automation; the company characterizes itself as an equivalent for customer experience inside the product rather than in customer service. The SDK-based delivery is presented as removing the need for product managers to depend on engineers.
Technology
The platform consists of a REST API backend, client SDKs for web, native iOS, Android, React Native and Flutter, and a dashboard for campaign management and real-time analytics. Integration options include SDK embedding or direct API use, third-party integrations, webhook and webview callback schemas, and an analytics schema. The offer-optimization side has been described as AI-based, using reinforcement learning ideas to tailor discounts against budget and margin constraints, with the predecessor product at Marax AI built as a proprietary churn-prediction engine.
Go-to-market
Customer acquisition has been sector-agnostic, spanning gaming, fintech, entertainment, content, D2C, e-commerce, edtech and utility applications. Early growth came from landing reference customers and then expanding into adjacent brands — after Purplle reported a 4x revenue uplift from its programmes, the company took on regional fashion retailer Zalora and subsequently Nykaa, and reported active conversations with PharmEasy and Paytm. Developer-led onboarding is supported by public documentation, quickstart guides and a CodeSandbox template. Proceeds from the pre-seed round were earmarked for expanding the product marketing and sales teams to scale customer acquisition globally, particularly in North America.
Mobile-first and consumer internet businesses, particularly e-commerce and D2C brands, plus fintech, gaming, edtech, entertainment, content and utility applications. Within those organizations the product is aimed at product managers and marketers who want to launch campaigns without engineering support.
Geography
The team is based in Bangalore, India. One source lists a Palo Alto, California address for parent organization Marax AI, Inc. Customers span India and South East Asia, and the company reported establishing a base in the United States with early proofs of concept there, naming North America as its priority expansion market.
History
The parent organization, Marax AI, Inc., began in October 2016 working on problems at the intersection of customer retention and B2C e-commerce, building a proprietary AI engine that predicted which customers were at risk of churning, why, and what actions would retain them. Marax AI worked with B2C companies including Orahi, Fynd, Nestaway and Petoo. Observing that roughly 80% of retention marketing actions were offers, and that deep discounting weighed heavily on e-commerce P&Ls, the team validated a new idea with more than 50 e-commerce companies and launched CustomerGlu in May 2020, following with an MVP in August 2020. In October 2020 the company was out of capital and the founders went without salaries for several months before signing Purplle as its first customer; BookMyShow followed in January 2021. Over 2021 the company raised pre-seed capital, joined the Techstars Bangalore 2021 cohort, and was named to YourStory's Tech50 2021 list of promising pre-seed startups.
Risks & controversies
The company experienced a severe capital shortage in October 2020, when the three founders went without salaries for three to four months and carried debt before its first customer contract provided runway. Its earlier behaviour-prediction product proved difficult to scale because each client maintained distinct datasets, and predictions alone did not translate into retention actions — a limitation that prompted the pivot to the current product.
