ATLANTA, Georgia and GRAND CAYMAN, Cayman Islands - Mobilewalla, a leading provider of data and vertical agentic AI solutions, and SPACSphere Acquisition Corp. (NASDAQ: SSAC), a publicly traded special purpose acquisition company, today announced they have entered into a definitive business combination agreement through which Mobilewalla will become a publicly listed company. 

Mobilewalla was founded in 2012 by Dr. Anindya Datta.  Since its founding, Mobilewalla has been focused on building a proprietary, exabyte-scale, research grade consumer data platform which provides high quality, privacy compliant data that is optimized to power vertical agentic AI solutions across multiple consumer facing industries. 

“I am excited to partner with Bala and his team to help accelerate Mobilwalla’s proven vertical AI solutions across our current  consumer facing markets, with an opportunity to accelerate our entrance into new markets, all of which we anticipate will benefit greatly from our approach,” said Dr. Anindya Datta, CEO of Mobilewalla. “We believe vertical agentic AI is the next frontier in the evolution of AI and solves industry challenges that horizontal AI cannot support.”

The company currently offers three vertical-specific products as part of their platform that drives actionable results across telecom, financial services and the marketing and advertising sectors. Mobilewalla’s current platform has been utilized globally by clients within its core verticals, and the company sees an opportunity to target a TAM of over $115 billion with a repeatable playbook into adjacent vertical markets.

Mobilewalla Data Platform includes:

• Feature Mart — a curated library of hundreds of pre-built, privacy-compliant data features and attributes engineered from Mobilewalla’s global data assets and designed to improve the accuracy and convergence speed of predictive models used in customer analytics, risk scoring, and churn prediction.

• Data Enrichment — an enterprise service that augments first-party data sets with additional consumer attributes such as behavioral trends, device-level information, and demographic signals enabling organizations to build a more complete view of their customers while maintaining compliance with applicable data-protection regulations.

• Audience Segments — pre-packaged or custom audience groups derived from thousands of behavioral and demographic attributes. These segments support digital marketing, personalization, and audience-targeting initiatives across advertising and communications platforms.

Vertical AI Solutions

• Market Flow (Telecommunications) — a competitive-intelligence and analytics suite for broadband and telecom providers. Market Flow helps operators measure market share shifts, assess customer churn and acquisition dynamics, and benchmark network performance relative to peers.

• Telescope (Telecommunications) – an agentic AI solution integrating data from multiple sources and employing an agentic framework to cost effectively and efficiently deliver mission critical insights by incorporating data from a variety of sources, core AI techniques and an understanding of industry nuances. Telescope combines Mobilewalla’s proprietary data with natural-language access and autonomous agents, allowing telecom clients to ask highly specific competitive and operational questions that generic AI tools cannot answer

• LendBetter (Emerging Market Financial Services & Fintech) — a data and analytics product tailored for lenders, enabling credit-risk modeling, identification of “new-to-credit” customers, fraud prevention, and portfolio optimization.

“We feel fortunate to partner with Anindya and the Mobilewalla team at this stage in Mobilewalla’s development, as they seek to expand into their large market opportunity for vertical agentic AI solutions that leverage their proprietary consumer data set,”  said Bala Padmakumar, Chief Executive Officer and Chairman of SPACSphere Acquisition Corp.  “We believe that the team is well positioned to deliver long term value for shareholders.”

Key Investment Highlights

• A proven platform built on 14 years of R&D investment, with three usage-based solutions in the market today generating $13.9 million of ARR as of April 30, 2026. 

• Attractive financial profile with 94% gross retention, 96% monthly recurring revenue mix, scalable gross margin profile and a clear path to near-term EBITDA breakeven.

• Proprietary Data Platform built on over 11 years of longitudinal signals is the foundation of a structural competitive data moat. The company has amassed a 400 PB data lake with over 5,000 consumer attributes and 250 predefined, predictive features.
