Deepvue is building the decisioning layer for AI agents — starting with identity, risk, and fraud infrastructure on India Stack. We solved data access. Aadhaar, UPI, DigiLocker, India Stack — the rails are world-class. But turning that data into high-stakes decisions still takes teams, manual reviews, and stitched-together vendor stacks. That's an industry-wide bottleneck. And it gets harder as fraud grows more sophisticated and regulation demands more transparency. The answer isn't more people. It's a stack that automates the decision and explains it — every layer, every time. Four layers deep: - Infrastructure (Live) — Connect to every data source in India, one integration. - Intelligence (Private Beta) — Turn raw data into signals that mean something. - Decisioning (Coming Soon) — Encode human judgment into rules that run themselves. - AI Agents (On the Horizon) — Systems that observe, decide, and explain without waiting for a human. Autonomy — without a black box. Today, we power API Infrastructure via 50+ API integrations across identity, business, document, face, banking, credit, and employment — serving 60+ businesses across 15M+ decisions. Trusted by India's fastest-growing FinTechs & Platforms. ISO 27001 certified. DPDP Ready. Backed by 100X.VC.

Retailers spend heavily to win a customer at checkout — then lose the same customer at their next device upgrade 18–24 months later. Each upgrade cycle effectively resets CAC to zero. Techster builds infrastructure that keeps that upgrade inside the same retailer checkout. We combine subscription mechanics, residual value modelling, and upgrade-timed routing to turn one-off device sales into predictable, multi-cycle recurring revenue. Instead of reacquiring customers through paid channels, retailers retain them economically — because upgrading at the same checkout is cheaper and easier than leaving. We start with UK iPhone-heavy retailers, where upgrade behaviour already exists (~80% of devices are on monthly payments). The infrastructure to capture those upgrades does not. Our model is asset-light and capital-efficient, partnering with finance providers rather than holding inventory. We are currently pre-seed and building toward 1–2 retailer pilots.

The BIG App was born from a personal struggle. I was broke, stressed about rent, trapped in minimum payments, watching debt grow no matter how hard I worked. I asked myself two questions: What do broke people want most? Money. What's second? Free things. That's where this started. I'm building a goal-based savings platform and debit card for everyday Americans tired of financial products that work against them. Every swipe of the BIG Card gives users a real chance to win meaningful cashback, automatically routed toward their most important goals. Paying off debt. Building savings. Getting ahead for once. No overdraft fees. No fine print traps. Just a card that fights for you. Save BIG. Buy BIG.

We are setting a new standard by building the Turnkey Alternatives Management Platform (TAMP) to help wealth managers run private market programs at scale.

Mason is building the AI workforce management platform for construction. We help contractors run their entire back office — time tracking, HR, payroll, compliance, and communication — without the manual work that slows teams down. Today, managing labor in construction is fragmented across paper field notes, spreadsheets, text messages, emails, HR platforms, payroll systems, benefits websites, and accounting tools. These workflows are ripe for unification and automation through AI and modern, cloud-based systems that connect the field and back office. Mason replaces firms' siloed tools with a single platform that connects the field to the office in real time — capturing hours, simplifying HR, running payroll, and ensuring compliance automatically. Our platform saves teams 20+ hours per week by eliminating repetitive data entry and reducing errors across HR, payroll and accounting. Workers get a modern, intuitive way to track time and manage their pay, while office teams receive clean, structured data that flows directly into payroll and job costing systems. Construction is the least-digitized major industry in the U.S. — and we’re changing that. Mason is a NYC-based, venture-backed company on a mission to bring AI-first workflows to the field. Come build the future with us! About our team: Our team is led by Matt Kozlowski (former Chief of Staff at Plaid) and Jef Chedeville (3x acquired/exited founder - previously co-founded YC-backed HR SaaS HigherMe).

We have a range of products and services across all five brands under BTC Inc.
