Michael Bloch brings an unusual combination of hands-on operating experience across the entire startup lifecycle—from early DoorDash regional GM to founding and selling Pillar to Acorns, then becoming a senior product leader—giving him direct perspective on building companies from zero to scale. He's one of the few venture partners who actively invests across both consumer fintech and national security/defense technology, having created detailed market maps of the defense startup ecosystem while leading investments in technical infrastructure companies like DragonflyDB and Mach9.
What they've been talking about across their social media accounts

- Focus on finding new moats in an era where artificial intelligence commoditizes software development. Points out that since intelligent tools make hard technical things easy, the real threat to traditional software businesses is that everyday customers or former employees can now build the products themselves. Believes durable companies must rely on hard to replicate advantages like network effects, liability bearing operations, or connections to the physical world such as hardware and manufacturing.
- Interest in hardware breakthroughs and new computing infrastructure that can solve processing bottlenecks. Closely tracks alternatives to standard industry graphics processing units, using Taalas as a prime example of a company introducing a faster and highly cost effective computing paradigm. Also notes that when deep tech companies like this face heavily polarized public opinion, it is usually a strong positive signal for investors.
- Advocating for updated startup compensation models that reflect massive productivity gains. Argues that because a tiny engineering team can now do the work of a massive legacy workforce using modern tools, standard startup equity grants are fundamentally broken. Suggests that founding engineers who replace entire departments should receive significantly higher equity stakes combined with longer vesting periods to ensure fairness.
- Valuing independent founder thinking and customer obsession over startup echo chambers. Highlights that while San Francisco is an incredible place to build a company, it suffers from a consensus problem where people naturally just agree with whatever is trending. Stresses that the absolute best founders distance themselves from that noise and stay closer to their actual end consumers rather than continuously networking with other startups.
- Active support for public policies that financially benefit early stage founders and startup operators. Spent considerable effort rallying the New York tech ecosystem to protect a specific small business stock tax exemption from being repealed by the state senate, arguing heavily that the incentive is vital because it uniquely rewards people who take the risk of building something completely from scratch.

Quiet Capital is led by founder Lee Linden, who built and sold social gifting startup Karma to Facebook and then ran commerce at Facebook, giving the firm deep operator experience rather than a traditional finance-only background. Despite maintaining a deliberately low public profile since 2017, the firm has quietly built stakes in recognizable companies like Reddit, Instacart, Epic Games, and Mercury while operating as both a prolific pre-seed leader and late-stage investor up to Series D.
