“And really, 90% of the time, the vast, vast majority of the time, founders get stuck in the very early stages. It's the very long unpaid design partnerships.”

Insight
Blomfield: Early startups waste time overbuilding platforms instead of narrow wedges
“What many founders do, which is a mistake, is to try and overbuild a really broad platform, which is a mistake at this stage of your company because you just don't have the resources. You can waste a lot of time without any real signal that a customer wants wh…”

Insight
Blomfield: Free B2B trials fail when run without clear end goals
“The most common problem for these free trials is again, they're too long, maybe two or three months, and they suffer from the same low commitment problems as a design partnership. There's no target or end goal, and the customer isn't really committed to engagi…”

Insight
Blomfield: Discussing pricing early almost never scares off enterprise prospects
“Founders are often very afraid to have a willingness to pay conversation. They feel like if they bring a dollar amount up, it might scare the customer off. But honestly, that's almost always not true.”

Insight
Blomfield: Early startup sales sell the founders, not a bug-free product
“Because your product is so early, you're never really selling a complete bug free experience. You're actually selling the founders and the early team. You're selling the promise that you personally are going to solve this problem for them.”

Insight
Blomfield: Reducing time-to-first-value is the top lever for pilot conversion
“Reducing it from weeks to hours is often the biggest single lever for higher pilot to paid conversion.”

Insight
Blomfield: Never require customer engineering time during a sales pilot
“I would never do a full API integration during a pilot if it requires any engineering time from the customer whatsoever, because that's just going to delay you by months.”
Tom Blomfield Aug 15, 2025 ▶ 12:51
Insight
Blomfield: Use Recurring Contracts With Opt-Outs Instead of Standalone Pilots
“So to get around this really sophisticated founders move on from paid pilots to recurring revenue contracts with an opt out period. So this is typically a monthly or annually recurring contract With a 30 or 60 day money back guarantee or opt out period at the …”

Insight
Blomfield: Early startups should accept customer contract terms unless company-ending
“So I'd be pretty flexible on signing, frankly, whatever your early customers want, as long as it's not going to expose you to like unlimited liability or container clause that's going to transfer all the IP in your product to your customer or something company…”
