Statements from this episode (18)
Looker grew from 15 employees at Series A to over 600
“The first week I was there was when Tomas closed the Looker Series A. They had 15 people there. I think now they have over 600, and they've raised hundreds of millions of dollars.”
Early-stage SaaS companies cannot hide fast growth from LinkedIn headcount tracking
“So if you're an early stage SaaS company, you can't really hide if you're growing fast. People can check your LinkedIn headcount, see how fast you're hiring on the website, what type of people.”
Top growth-stage software companies do not need venture capital
“At the end of the day, the best companies in growth don't need the money, and so that makes it pretty tough”
Founders should limit non-fundraising meetings to investors who add tangible value

SaaS growth stalls at $10M to $30M ARR without sufficient market depth

Absence of competition indicates a B2B SaaS market isn't large or interesting
“I think at a very high level, if there's no competition, it's not really a large, interesting market. I don't think there's any free lunch in B to B or SAS anymore. Every large market, every large company is going to have competitors.”
Spark Capital conducts 10 to 15 customer reference calls per investment
“For the best companies, I feel like once you do 10 to 15 calls, and they're all starting to sound the same, you know you've sort of figured it out. But we like to do at least that many for every company that we're thinking about investing in.”
Capital is only a temporary competitive advantage in enterprise software
“It's certainly a competitive advantage, but I think it's only temporary. But it can still have big impacts on markets. So in the early days, for sure, but I think at some point, the rubber meets the road. These companies are going to have to go public. They're…”
ServiceNow grew to $43B market cap by launching new products annually

Growth investors should prioritize software that is critical to business continuity
“At the end of the day, it's like, is this product core to business continuity? So what does that mean? If you ask the customer or stakeholder, If you rip this thing out or if it shuts off, what's going to happen to their business? I think the best products are…”
Best-in-class SaaS companies need 75% of ramped reps hitting quota
“I think you want to have at least 75% of your ramp reps at a hundred percent of quota.”
Realistic SaaS payback periods are 15 to 18 months, not 12
“15 to 18 months for high growth businesses is what we like to see. Very rarely, everyone talks about 12, it's very hard to get it down to that level.”
Best-in-class $5M to $20M ARR SaaS grows 7.5% to 10% monthly
“Let's just say you're kind of between five and 15, 20 of ARR. I think you want to be growing seven and a half to 10% month over month. That would be best in class.”
High-growth SaaS companies should target 130% plus net dollar retention
“I think on a net expansion or net dollar retention, which is kind of the North Star number that we focus on, you want to be a 130% plus.”
Median 2018 SaaS IPO took 15 years and reached $200M ARR
“You had to be around about 15 years. You're about two hundred million plus in ARR, growing around 40%, have 75% gap gross margins, are losing money, have at least 120% net dollar expansion rate, sell a thirty-k product per year on average, Have about a thousan…”
Public cloud penetration is only 7% of the $600B enterprise IT market
“We're only about seven percent penetrated in what is a six hundred billion dollar plus enterprise IT market.”
The 'move fast and break things' philosophy fails in enterprise SaaS
“I think for SaaS companies, moving fast and breaking things, you can't break things for your customers. You don't get many opportunities. You've got to deliver a great customer experience from the onset.”
Braze will win marketing automation over legacy giants Salesforce, Adobe, and Oracle
“Braze. It's an incredible team and product in the marketing automation space. They are helping company large brands figure out how to engage with their customers and giving them a single view of their business across channel. And that's something that Salesfor…”
