Wakemate

WakeMate makes personalized alarm clocks that sync with both a user's body and their cell phone, enabling the iPhone alarm system to sound at the end of a REM cycle. The application/ wristband system also provides a full sleep analysis on their Analytics Platform. The WakeMate uses a science called actigraphy to analyze your sleep. Actigraphy uses an actigraph (the WakeMate unit) placed on a subject’s wrist to monitor the motion. The motion data is then analyzed to determine sleep patterns and circadian rhythms of the subject. WakeMate was funded by the startup incubator Y Combinator.

Warmly, logo

Warmly,

Autonomous sales platform to auto-email your warmest leads

Step 1: We find you warm leads: contacts + companies that are showing interest on your website (via 6sense/Clearbit) and researching you around the web (via Bombora) but haven't converted yet. Step 2: We then auto follow up via chat, email or LinkedIn. Depends what workflows you want to set up - we can AI chat with them on your website, auto AI email them via your sequence provider of choice, and/or auto AI linkedin sequence them. Your humans can verify everything before being sent too.  Outcome: 10x more outbound than a human SDR, 3x reply rates since they're warm and more booked meetings (results shown in ROI dashboard).  P.S. if you want to use humans: you can send 1-click warm intro requests via your network or live chat/video call them too. This is the power of an autonomous sales orchestration platform and we have 100+ paying customers who can back it up.

Warpfy

Building Shein of Home: tech-driven, design-mfr Home Lifestyle Brand

The Fine Living Company (Warpfy) is on a mission to revolutionize the $800B home and kitchen market, building a tech-enabled cross-border Home Lifestyle brand from India—think Shein for Home or Williams Sonoma. Our Design-to-Manufacture-to-Consumer model cuts out the middlemen, delivering high-quality products directly to consumers (D2C), through marketplaces, and via our proprietary B2B channel, The India Wholesale Company). With a fragmented market where 70% is dominated by single-store boutiques and online penetration is just 20%, Home and Kitchen segment is ripe for disruption. India’s share of products has been minimal due to 60%+ value inflation from intermediaries. We’re changing that. Our full-stack approach: AI Copilot-driven product design, ERP for multi-channel distribution & manufacturer retention, and optimized supply chain—offers unparalleled speed & value.
