Top Tech Startups to Work For in 2027

Sequence Holdings is a permanent holding company that brings AI and engineering to the core of great American businesses.

We have recently taken on a 3D modelling long-term Modelling & Simulation project focused on developing commercial-grade hard-surface vehicle assets for professional visualisation and digital production. The project involves creating highly detailed, technically accurate 3D vehicle models from reference material, with a strong focus on clean topology, accurate proportions, surface definition and production-ready geometry. Using Blender and established 3D asset-development workflows, the project encompasses the full modelling pipeline, including hard-surface modelling, UV unwrapping, material and texture development, lighting, rendering and final asset preparation. Our objective is to deliver high-quality, commercially viable 3D assets that meet professional standards for visual accuracy, technical consistency and presentation, while maintaining an efficient and scalable production workflow.

MandAPI is building the affordable AI infrastructure layer for Latin America, starting in Brazil. Our Vision AI is transforming how the world builds software, but access remains fragmented, expensive, and unnecessarily complicated — especially for developers in emerging markets. We believe powerful AI should be accessible to everyone, regardless of geography, currency, or company size. What We're Building MandAPI provides a unified, OpenAI-compatible API that connects developers to leading AI models, including GPT, Claude, Gemini, DeepSeek, and more. With a single integration, developers can access multiple models, compare transparent pricing, and build AI-powered applications without managing separate provider accounts. Starting in Brazil, we offer pricing in Brazilian reais (BRL), local Pix payments, prepaid credits, and flexible pay-as-you-go billing. Beyond the API We're developing an ecosystem of tools around AI infrastructure: MandAPI Gateway: Unified access to multiple AI models through one API. MandAPI Connect: A desktop experience for AI-powered coding workflows. MandAPI Radar: Model discovery, pricing intelligence, and AI ecosystem insights. Our Mission To remove the financial, technical, and geographic barriers between developers and the world's most powerful AI technologies. We're an early-stage, product-driven project focused on developer experience, affordability, and rapid experimentation. Our journey starts in Brazil. Our ambition extends across Latin America. One API. More possibilities. Less cost. mandapi.com

We're rebuilding India's $17B MEP industry around software. Mechanical, Electrical, Plumbing, HVAC, Fire Safety — the physical infrastructure behind every commercial office, retail outlet, warehouse, and hospital. It's a massive market with no scaled, tech-enabled player. Work sits with line contractors at the bottom of the construction value chain, and they stay sub-scale for structural reasons: sales is informal, procurement is local and expensive, execution knowledge sits in the owner's head, and there's no documentation. Nirmaan is the first MEP contractor built around proprietary software end-to-end. Our platform — the Nirmaan Stack — runs every stage of a project's lifecycle, from the first sales call to final handover. One team runs 70+ live projects across 20 cities at once, a scale conventional line contractors simply can't reach, because growth no longer depends on how many experienced people we can hire. Clients include Decathlon, Siemens, Grant Thornton, Cushman & Wakefield, Hexaware, HomeLane, Sterlite, Table Space, Kearney, Wakefit, HCG Hospitals, D E Shaw & Co, and 30+ others. The Nirmaan Stack — live in production: • Sales CRM — account mapping, BOQ pipeline, salesperson-wise conversion tracking • AI BOQ Engine — estimation turnaround cut from days to hours • Procurement Engine — centralized RFQs against a live rate history, so every buy is benchmarked • Project Intelligence — site-wise progress, manpower and material tracking against budget • Cash Sheet — per-project live margin and receivable position • Project Record — full digital trail per project Why this matters: a traditional line contractor holds all of this in the founder's head. Because our software holds it instead, we price off data, procure centrally, and open a new city on a repeatable playbook. That's what turns a relationship business into a scalable one.
