Date: October 31, 2025
Host: Jennifer (a16z)
Guests: Robert Ng, Advith Chelikani, Marty Cautious (Co-founders of Pylon)

Overview

This energetic and deeply candid episode goes inside the startup journey of Pylon, an AI-native customer support platform shaping the future of B2B support. Pylon’s founders—Robert Ng, Advith Chelikani, and Marty Cautious—discuss their path from scrappy beginnings (including still living together in a windowless apartment) through intentional company culture building, relentless product bets, and the vision to become “the operating system” for customer-facing teams. The discussion explores why B2B support remains an unglamorous but massive opportunity, how to create fun and intensity in a "grinder" culture, why building in public matters, and how AI and product focus set Pylon apart.

Key Discussion Points & Insights

1. Pylon’s Founding Story & Unique Living Situation

[00:01–03:28]

• The founders emphasize a “happy grinders” culture: high-competency, low-ego, intensely debate-driven, and deeply all-in—illustrated by their choice to share a modest apartment even after success.

  “People think, oh, you’re series B now, you’re doing so well, you probably have a nice living situation. No, we live in like a dinky apartment… we are very, very scrappy.”
  —Robert Ng [00:23]

• Their founding was based on compatibility, not the idea:

  “You shouldn’t choose your co-founder based on the idea you’re working on because you’ll probably pivot.”
  —Advith Chelikani [00:35; 21:35]

• Early connections: The trio met via Caltech, the KP Fellows internship (at DoorDash, Slack, Airbnb), and ultimately chose to work (and live) together after several “co-founder dating” rejections before aligning on shared goals.

2. Debunking the “No Fun, AI-Era Founding” Myth

[03:28–05:25]

• The Wall Street Journal’s depiction of relentless, joyless AI-founding is challenged:

  “One thing [the article] got really wrong…we are very motivated by fun and adventure… Even if you’re really passionate, it’s not worth spending 12 hours a day on just any problem. So, for us, fun is definitely our core motivation.”
  —Robert Ng [03:58]

• Work intensity is real—minimum six days a week—but passion and joy, not just grind, drive it.

• Despite the emphasis on effort, they invest in sleep (“Our mattresses are expensive” [04:53]) and intentionally create a sense of adventure.

3. Culture: Debate, Scrappiness, and In-Person Energy

[05:25–12:41]

• Peer Pressure and Employee Culture:

  • While founders work extreme hours, they clarify this is not an explicit expectation for employees. Still, founder intensity sets a “bar,” especially for new leaders.

    “As founders, we’re 996 and we’re very happy to do 996 or more, but for employees… it’s about output and moving fast, not about hours.”
    — Marty Cautious [07:06]

• In-person work increases collaboration and speed.

  “All eat lunch together….has helped us get away with way less process…because people ended up talking to each other.”
  —Advith Chelikani [10:48]

• Transparency: Every deal, win/loss, and live company metrics are shared with the team.

  “…everyone sees every deal that is won and the amount, every person sees what deals are lost and the reason…also like a live company dashboard that everyone can see our revenue every single month.”
  —Robert Ng [11:11]

• “Happy grinders,” “high-competency, low-ego,” and debate are cultural foundations, making even fierce arguments feel like “debating for sport.”

4. Building in Public and Personal Branding

[12:42–16:39]

• Pylon leverages LinkedIn for direct customer engagement and brand-building, helping pipeline generation and public perception.

  “When we started it was just, hey, we want to produce pipeline. This other YC founder told us that it’s working for them. And so we just started posting…anything about…customer support on Slack. …Then there was one post that…absolutely took off.”
  —Robert Ng [14:39]

• Robert’s follower count grew from five to 45,000; public storytelling was not planned but became key to creating “perception” of momentum.

5. Product and Market: The B2B Support Wedge and Evolution

[16:53–38:09]

• Why B2B? Most support tools serve consumer needs; B2B firms need integrated tools for support, customer success, account management, solutions, etc. — all of which Pylon aims to unify.

  “We’re the first customer support platform that’s built for B2B companies…we’ve built one product that’s encompassing all the needs of all those teams.”
  —Robert Ng [16:53]

• Idea Selection and Pivoting: Their journey was driven by desire to build a large, defensible company, focusing on market size and “why now.”

  “The business is really important…if you observe why did some companies get to $10 billion market cap…market was a really, really big differentiator…so you may as well choose the mega markets.”
  —Robert Ng [26:33]

• Discovery of the B2B conversational “why now”: Customers shifted to support over Slack/Teams/Discord, creating new needs and opportunities.

  “Our first insight was…many customers are talking to their vendors over shared slack channels…none of it’s being tracked…there’s no solution to help.”
  —Robert Ng [29:07]

6. AI-Native Approach and Competitive Differentiation

[33:34–38:09]

• Pylon’s formation coincided with the ChatGPT launch, enabling an AI-native product from the outset.

  “We built everything in an AI native way because we knew it existed from basically the beginning…a lot of the other people in our batch were just like throwing AI at the wall and seeing what would stick. We went to customers first, figured out the problem, made sure that AI actually was the answer.”
  —Marty Cautious [34:34]

• Focus: Using AI not for generic chatbots, but for transforming unstructured B2B support data—auto-tagging, context summaries, proactive signals, and more.

  “Now…you can build these signals that tell you, hey, this customer might be interested in purchasing this additional SKU, or hey, they're at risk of churn…structure it into these signals or different fields and then build automated workflows off of it.”
  —Robert Ng [36:08]

• Vision: Not just competing on tickets—building the “operating system” for all customer-facing teams, leveraging AI for scalable, cross-functional solutions.

7. Strategic Vision & Multi-Product Expansion

[37:30–42:22]

• The founders aspire to be a “compound startup” (Rippling as model), rapidly creating new verticals (support, account intelligence, customer ops).

  “We're taking a very rippling-like strategy. We're trying to be a compound startup and spin up several different verticals…it's a very risky but high risk, high reward kind of strategy.”
  —Marty Cautious [37:44]

• They focus on fast-growing mid-sized firms (not just large enterprise), teaching them the “Pylon way” as they scale.

• The thesis: AI enables a vastly larger surface area, allowing one engineering team to build what previously might have taken multiple companies.

8. Decision-making, Debate, and Startup Intensity

[43:15–46:44]

• Decision-making is debate-heavy, with arguments framed around building a generational, public-company scale business.

  “We solve all problems in the company by debating super heavily…it’s like the steel sharpen steel mentality…we just debate ideas heavily…if we can't make a decision, it means we don't have enough information…and if it's not critical or priority enough, we have to push it.”
  —Robert Ng [44:15; 45:30]

• As the company grew, debates moved from public to private to avoid alarming employees, but the founders describe the process as “incredibly fun…debating for sport.”

Notable Quotes & Memorable Moments

• “You shouldn’t choose your co-founder based on the idea you’re working on because you’ll probably pivot.”
  —Advith Chelikani [00:35; 21:35]

• “The business is really important… For us, it’s like the business is really important.”
  —Robert Ng [00:39; 26:33]

• “Fun and adventure is one of the best reasons to start a company… For us, that’s definitely our core motivation.”
  —Robert Ng [03:58]

• “We're very transparent and very direct. We just debate ideas until we get tired and there's no ego in it.”
  —Robert Ng [11:11]

• “We all eat lunch together for the most part. That’s helped us get away with way less process or cross-functional things for a longer amount of time.”
  —Advith Chelikani [10:48]

• “Now you can build a company like this that has this product surface area…we are moving—I think we might be the fastest company to ever execute this type of strategy.”
  —Robert Ng [42:22]

Conclusion

Pylon’s founders combine discipline and debate with a surprisingly playful approach to “grind” culture, using it as both a competitive edge and a source of sustainable joy. Their strategic clarity around building a B2B “compound startup” for customer ops—using AI as an enabling lever—and their willingness to challenge both startup and industry norms (in public, and sometimes in pajamas) makes them a unique force in enterprise SaaS. The operating system for the next generation of customer-facing teams might just come from a windowless apartment powered by three friends arguing for fun.

For listeners who want to understand startup grit, the real-world application of AI in SaaS, or the anatomy of a modern high-performance founder culture, this episode is a must.
