Top Tech Startups in United States in 2026

Marble is a climate tech venture studio solving hard climate problems. Our mission: bring us at least one gigaton closer to net zero and create a future that thrives. We do this by partnering with scientists, engineers and operators to build deeptech startups that slash emissions, remove carbon, and cool the planet. The climate crisis is the most pressing challenge of our times. Solving it requires breakthrough technology, as available solutions only get us halfway. We can’t put all our hopes in classic tech transfer. We need to intentionally create and deploy radical solutions for hard-to-abate emissions. Backed by top climate and deep tech investors, we're searching for individuals who could apply their skills to solve hard climate problems and who have the will to turn their skills into a new startup company. Joining as Founders-in-Residence, they work with us to scope high-impact climate opportunities and build ventures with massive impact potential. We invest in the best teams at pre-seed.

What We Are Building We are a proprietary digital marketplace modernizing the personal styling and fashion tech ecosystem. Currently operating in a private beta phase, our platform architecture is fully functional, launched, and validating successfully with an active user base. To protect our market entry strategy and proprietary user data, we are maintaining complete brand confidentiality during this early growth phase. The Strategic Opportunity While retail & fashion represents a multi-billion dollar global market, the consumer demand for personalized styling remains highly fragmented, opaque, and underserved. Historically, scaling this sector has suffered from prohibitive inventory overhead and logistical limitations. We are solving these inefficiencies through an asset-light, multi-sided marketplace model that connects consumer demand with expert personal styling services - eliminating inventory risk entirely while maximizing scalability and margin potential. The Partnership The company is led by an experienced business founding team with deep domain expertise and operational track records. We are expanding our executive suite to include a long-term Technical Co-Founder/CTO. This individual will take complete ownership of the technical roadmap, audit and optimize the existing platform infrastructure, and act as a strategic partner as we position the business for future institutional capitalization. (Full documentation and product access will be shared transparently with qualified candidates post-introduction.)

Whipair helps car dealers and car buyers close deals faster and easier. Today, after a customer agrees on a car, dealers still rely on calls, emails, PDFs, and manual follow-ups to complete the transaction. This slows deals down and causes drop-offs. We built a simple and standard journey that lets dealers go from “yes” to a signed and paid deal in one flow.
