E1121: Mark Suster on investing in human-computer interfaces & sustainability, what he looks for in founders, SPACs impact on early-stage investing & more

Episode Summary

Executive Summary: Jason Calacanis and Mark Suster discuss Density, computer vision and sensor-driven startups, continuous health monitoring, sustainability investing, politics in the workplace, and the effects of SPACs and COVID on venture markets. The conversation broadens into weight loss, public policy, education, capitalism, and geopolitics, with Suster emphasizing bias toward action, privacy-first product design, and long-term investing in resource-constrained future markets.

Main Topics: Density and privacy-first physical-world sensing (Priority: 5/5): Suster explains why he invested in Density: a privacy-compliant, non-camera system using lasers/radar to understand occupancy and proximity in office, hospitality, warehouses, and other spaces. Computer vision, HCI, and ambient health monitoring (Priority: 5/5): He lays out a broader thesis that computers can interpret the physical world better than humans and gives examples like Ring, Nanit, and continuous monitoring for infant, senior, and disease detection use cases. Sustainability and resource security investing (Priority: 5/5): Suster frames sustainability as investing in solutions to water, food, energy, and climate constraints, citing Apeel, insect-based fish feed, and zero-mass-water as examples of scalable infrastructure bets. Politics, inclusion, and workplace norms (Priority: 4/5): The discussion addresses Brian Armstrong’s 'politics at work' memo, arguing companies need structured, safe forums for employees to discuss social issues rather than banning the topic entirely. SPACs, liquidity, and the public-private market shift (Priority: 4/5): Suster argues SPACs can be both positive and negative: they create earlier liquidity and access to capital, but some of the biggest value creation has moved to private markets over the last decade. Weight loss, glucose monitoring, and behavior change (Priority: 4/5): The hosts compare their own weight-loss journeys and discuss how continuous glucose monitoring, portion control, and walking changed eating behavior and health outcomes. Capitalism, regulation, education, and governance (Priority: 4/5): Suster defends capitalism as the best system available while acknowledging its flaws, supports some government intervention, and argues for education reform, competition, and earlier vocational/pre-K interventions.

Key Arguments: Computers can interpret the physical world more accurately and continuously than humans, creating opportunities in security, healthcare, retail, and operations. Privacy-first sensing will outperform camera-based systems in many enterprise and consumer environments because it avoids surveillance concerns and can be cheaper to process. The best founders show a bias toward action through product shipping and talent attraction rather than persuasive storytelling alone. Sustainability is not a branding exercise; it is a five-to-seven-year investment thesis around water, food, energy, and waste reduction. COVID accelerated technology adoption by several years, making telemedicine, delivery, scheduling, and workplace sensing more mission critical. SPACs can unlock liquidity and capital, but the most valuable companies increasingly stayed private longer, shifting gains away from public markets. Workplaces should not ignore politics; instead, they should create intentional, opt-in forums that preserve employee psychological safety and focus. Capitalism remains the strongest system for broad value creation, but requires regulation, competition, and anti-corruption safeguards. Education should move toward earlier intervention, more vocational training, and less reliance on a universal four-year degree model. Government and regulation often lag innovation, so startups frequently have to push boundaries ethically and then seek forgiveness rather than permission.

Data Points: Density bookings growth: 550% quarter over quarter - Suster cites COVID-era acceleration as Density moved into mission-critical uses such as warehouses and logistics. Nanit revenue: tens of millions of revenue - Suster says Nanit has built one of the largest infant-growth datasets in the U.S. and is doubling rapidly. Nanit data growth: more than doubling every year - Based on the expanding corpus of infant and toddler development data. Ring investment pattern: seed through E round - Suster notes Upfront backed Ring repeatedly across multiple funding rounds. Upfront companies above $1B valuation: 16 companies - Used to illustrate the firm’s long history and multiple unicorn outcomes. Suster peak weight: 222 pounds - His personal health story before losing weight through fasting and calorie control. Current weight: 154 pounds - Suster says he lost about 70 pounds over roughly 15 months. Weight-loss timeframe: 15 months - Used to emphasize the discipline and consistency of the transformation. Daily calorie target: 1,800 to 1,900 net calories - Suster describes quantified eating as central to his weight loss. Glucose monitor use: 30 days - Calibrate his eating decisions and understand spikes from specific foods. Restaurant delivery shift example: ~$20M to $80M revenue - Suster cites ChowNow as benefiting from COVID-driven adoption of delivery software. Retail waste reduction with Apeel: avocado waste from about 10% to about 2% - He uses Apeel as an example of sustainability-driven product impact. Citrus waste reduction with Apeel: from 6-7% to less than 1% - Illustrates how shelf-life extension improves economics and sustainability. Apeel sales lift in grocers: more than 40% - Suster says grocers using Apeel saw increased sales due to lower spoilage. Fish feed company scale: north of $100 million in bookings overnight - He describes explosive demand for insect-based fish feed. Water generation product: one case of water every day from two roof panels - Suster mentions Zero Mass Water as an example of atmospheric water generation. Bird ride margin: very positive contribution margin on every ride - Suster argues Bird’s unit economics are stronger than critics claim.

Pivotal Quotes: "The interesting thing is that computing devices are much better at interpreting the physical world than human beings are." — Mark Suster: Explaining his investment thesis in computer vision, sensing, and human-computer interfaces. "What I was going to mention about levels is I just amazed that they're biased towards action and ability to get stuff done." — Mark Suster: Describing what he looks for in founders and why execution matters more than rhetoric. "If you want to have people of color... you can't put your finger in your ear and say things like homeless that don't matter or black rights don't matter." — Mark Suster: Arguing that employers must acknowledge societal issues and provide safe internal forums for discussion.

Implications: The episode reinforces a thesis that sensing, health tech, sustainability, and logistics software will keep winning as COVID-era behavior changes persist. Founders should prioritize execution, privacy, and ethical disruption while investors should expect more private-market value creation and more public scrutiny.
