Despite being hired as a semiconductor expert at USVP, Hamid realized the future was in software by observing his peers and attending Web 2.0 events after work. He taught himself the software space as a "side project," which eventually became his main focus, demonstrating the power of informal networking.

Horizontal SaaS companies fracture their customer knowledge across diverse industries, forcing generic messaging. Vertical SaaS companies build compounding knowledge with each customer within a niche. This leads to deeper insights, stronger competitive secrets, and more effective, specific messaging over time.

According to Box CEO Aaron Levie, the stickiest SaaS products are those with strong network effects, deep integrations, and mission-critical workflows. A simple heuristic for vulnerability: if you can get the same value from a fresh install as a decade-old one, your product can be easily replaced by AI-generated software.

Enterprise products must solve the complex, day-to-day problems of the implementers, not just the C-suite buyers. Slack built a dedicated admin dashboard separate from executive-level metrics to serve the critical but often ignored IT admin, whose job is facilitating work for thousands.

Analyzing over 200 investments, TinySeed observed that vertical SaaS companies consistently achieve stronger exits, grow further, and have lower churn than horizontal SaaS. This data-driven insight has shifted their investment thesis toward more defensible, niche-focused companies, as they have proven to have distinct advantages.

Directly approaching large organizations is often ineffective. Instead, emulate Slack's growth model by getting individual employees to use and love the product. This creates internal champions who advocate for wider organizational adoption, pulling the product in rather than pushing it from the outside.

Slack's founder shut down his popular game, Glitch, because he felt it wasn't the right path, despite having millions in funding. He embraced the unknown and pivoted to an internal tool the team had built. This demonstrates that breakthrough opportunities are often discovered through a willingness to face uncertainty, rather than being meticulously planned.

Mamoon Hamid, a top Series A SaaS investor, has a unique talent for identifying the precise moment a company's trajectory 'kinks' upward, even with very little data. He did this with Figma at only $500k ARR by seeing the usage curves inside key early customers like Google, recognizing the inflection point before anyone else.

Enterprise buyers purchase tools like Slack because employees love using them, not based on clear ROI. This presents a major adoption hurdle for non-viral, single-player products like enterprise search, which must find creative ways to generate widespread user adoption and love.
