Mid-stride in a market he created

Marty Kausas does not have a customer support background. He has a Purdue CS degree, a stint at Airbnb he describes as something he "absolutely hated," and a theory that the entire enterprise support industry was built for a world that no longer exists. He founded Pylon in November 2022 alongside Advith Chelikani and Robert Eng, and has since raised $51 million, signed 1,500+ enterprise customers, and positioned the company as the definitive challenger to Zendesk in the B2B market.

Pylon's core insight is structural. Consumer support works fine with a single customer-facing team. B2B support involves customer success managers, solutions engineers, professional services, and support engineers - all touching the same account, scattered across Slack channels, email threads, and Microsoft Teams. No existing tool handled that complexity. Kausas decided to build the one that does.

The platform integrates across Slack Connect, email, Teams, and Discord to create a unified inbox with AI-powered workflows, SLA management, knowledge bases, and CRM integrations. It is not a bolt-on. It is a full replacement - and the "Migrated from Zendesk" logo wall on Pylon's homepage is deliberate.

"In B2C you only have one team that's customer facing - customer support. In B2B you have customer support, customer success, solutions, professional services."

18 months of failure, then the couch

After graduating from Purdue, Kausas went through a standard-issue elite startup sequence: intern at Qualcomm, intern at Yelp, Engineering Fellow at Kleiner Perkins Caufield & Byers, software engineer at Clipboard Health, then Airbnb. The Airbnb chapter ended when he decided to build something himself. What followed was 18 months of ideas that didn't stick.

When he landed on the Slack connector concept in late 2022, the validation was almost absurd in its immediacy. He walked upstairs in his San Francisco hacker house and found Tejas from Hightouch sitting on the couch. He asked about the problem. Tejas said they were actively looking for exactly that solution. Pylon had its first customer before it had a product.

The pricing conversation that followed became a formative lesson. Kausas's team suggested $15,000 without any anchor or justification. Hightouch pushed back and they landed at $2,700. The education was cheap. Every future sale would be different.

Anecdote

Marty found Pylon's first customer within minutes of having the idea - literally sitting on the couch in his hacker house. Tejas from Hightouch was already looking for the exact solution Marty had just conceived. The first deal was signed before a single line of production code was written.

The Sunday session that built a pipeline

Kausas is an engineer. He had zero sales experience when Pylon launched. So he engineered a sales system. Each of the three co-founders sent 40 personalized LinkedIn messages per day to professionals with titles like "support engineer" and "customer success manager" - 120 total. The messages were not blasted. They were researched, specific, and focused on understanding the problem rather than pitching a product.

He calls the approach "anti-selling." Ask questions until someone admits they have the problem. Don't explain why the product is great. Find out if there's genuine pain first. If there is, the sale almost closes itself.

The content engine runs on a different discipline. Every Sunday, Kausas spends 5+ hours at a local coffee shop writing LinkedIn posts - roughly 9 per session, for all three co-founders' accounts. He writes every post. The result is approximately 50% of Pylon's total pipeline flowing from organic LinkedIn content - a ratio most startups would trade a product feature to achieve.

His explanation for why highly credentialed people struggle with public visibility: fear of embarrassment. His prescription: "You just have to get over that."

"People like people. They don't like companies."

Three rounds, all faster than expected

Pylon closed its $3.2M Seed in 6 days in early 2023 - during the week Silicon Valley Bank collapsed. The approach was unconventional: Kausas replaced the standard pitch deck with a Notion memo, scheduled 46 VC meetings across 6 days, and closed General Catalyst at a sushi dinner. Back-channel introductions from customers championing Pylon to investors created the kind of momentum that compressed the usual timeline by months.

The Series A story is even sharper. Pylon had been cash-flow positive for three months and was not fundraising when one investor expressed interest. Word spread fast. The $17M Series A from Andreessen Horowitz closed in 14 days. The company didn't need the money. That's the point.

The $31M Series B, co-led by a16z and Bain Capital Ventures and announced in August 2025, brought total funding to $51M with participation from General Catalyst, Y Combinator, and existing investors. The use of funds is pointed: expand the AI platform, grow the team, and accelerate what Kausas has called the mission to "reinvent B2B support."

Kausas on building

"We set a goal for ourselves to build a $10 billion plus public company."

"Story-telling about how BIG you can become is more important than traction at Seed."

"You should anti-sell your product quite early."

"Speed remains the most important advantage startups have when competing against large incumbents."

"We raised Pylon's $17M Series A in 14 days. We didn't need the money. We had been cash-flow positive the past 3 months."

"Sales [is] like debugging code." - on how he approached selling as an engineer

$10 billion, built deliberately

Kausas does not talk about building a billion-dollar company as a surprise outcome. He talks about it as a founding thesis, set before the first customer signed. The specific number he cites - a "$10 billion plus public company" - is less a boast and more a design parameter. He started Pylon knowing what category of outcome he was attempting to engineer.

The competitive positioning reflects this clarity. Pylon calls out Zendesk and Salesforce Service Cloud by name, frames itself as the modern replacement, and uses a "Migrated from" logo wall on the homepage to show which enterprise customers have already switched. This is not diffidence. It is a company that believes the incumbents built for a B2C world and are now fighting a rear-guard action against a platform built specifically for how B2B actually works.

With 1,500+ customers including Together AI, Cognition, Temporal, and AssemblyAI - and an AI-native architecture at a moment when enterprise software is being rebuilt from scratch around large language models - Pylon is positioned at the intersection of two large shifts simultaneously: the migration of enterprise support away from legacy ticketing systems, and the integration of AI agents into every customer-facing workflow.

Kausas describes the culture at Pylon as "happy grinders." The tension between speed and quality, between moving fast and building something durable, is something he thinks about explicitly. The company has 120 employees. The goal is a public company. The path between those two points is the work.
