Top Tech Startups in Silicon Valley in 2027

Coastal Carbon is a seed-funded startup on a mission to create positive impact through earth observation and AI. Founded at the University of Waterloo by a team of PhDs and engineers, we’re backed by some of the best AI and climate tech investors like HF0, Inovia Capital and Propeller Ventures, angels like James Tamplin (cofounder Firebase) and Sid Gorham (cofounder OpenTable, Granular), and partners like Amazon AWS and the United Nations. We’re building multimodal foundation models for the natural world. We believe there’s more to the world than the internet + more to intelligence than memorizing the internet. Our models are trained on satellite remote sensing and real world ground truth data, and are used by our customers in nature conservation, carbon dioxide removal, and government to protect and positively impact our increasingly changing world. Our ultimate goal is to build AGI of the natural world.

We are building a family of smart turrets that can take precision shots at swarm drones to neutralize the threat at a very low cost per engagement.

HEAL (Healmenow Inc.) is building the first screenless, voice-first companion for medication adherence and mental wellness. Instead of another app competing for screen time, HEAL lives as a physical device in your space — you talk to it, it responds, it helps you stay on track with your care. We sit at the intersection of hardware, AI, and emotional design, because behavior change doesn't come from reminders and gamification — it comes from feeling understood. What We're Building A screenless medication adherence device paired with an AI voice companion. Say "Hey HEAL" and it dispenses your medication, logs adherence, and has a real conversation with you about how you're doing — building the kind of clinical documentation that qualifies for Medicare Remote Therapeutic Monitoring (RTM) reimbursement. V1 is built and working; we're now developing V2 using real user data, targeting a significant jump in treatment effectiveness. Our voice companion also carries a crisis-escalation layer, built with clinical oversight from a psychiatry advisor with 15+ years of experience. Hard Problems We're Solving Medication non-adherence, especially for mental health conditions, is a massive and under-addressed problem — people don't stop taking their medication because they forget, they stop because no one is checking in on how they actually feel. Existing solutions (pillboxes, reminder apps) treat this as a logistics problem, not an emotional one. We're solving three hard problems at once: designing a voice AI that can hold a caring, clinically-sound conversation without a screen; building the crisis-detection logic responsible enough to flag real risk without false alarms (the single highest-risk, highest-scrutiny part of the FDA classification question); and proving this new adherence data can actually satisfy Medicare RTM reimbursement requirements, which is what will make this sustainable at scale rather than another wellness gadget.
