IT'S NOT JUST YOU. CUSTOMERS ARE ASKING FOR SHORTER AND SHORTER CONTRACTS IN THE AGE OF AI

Enterprise buyers are increasingly demanding shorter contract terms because the rapid evolution of artificial intelligence makes them hesitant to lock into multi-year commitments. Recent data shows that sales cycles have compressed while sub-one-year contracts have risen significantly as customers try to keep their software options open.

YOUR AI FEATURE IS QUIETLY DESTROYING YOUR GROSS MARGIN

AI needs to be treated like traditional SaaS COGS. The classic SaaS model was built on high gross margins and low marginal costs. However, add AI inference costs, model-routing costs, vector database costs, and other AI infrastructure, and that margin profile can change fast. AI can create a better product, but it can also quietly pressure the most important leverage point in the SaaS financial model. Businesses need to learn to isolate that pressure in their SaaS P&L, otherwise they will feel it everywhere.

GREAT COMPANIES ARE BUILT IN HACKATHONS

PostHog has shipped four real products out of hackathons. Logs became one after someone ran the math on Datadog's bill and saw $260K a month. The rules are what make it work. Nothing from the roadmap, no sneaking regular work in, non-engineers participate. It treats hackathons the way most companies treat roadmap planning, which is why they actually produce companies.

THE RUMPELSTILTSKIN EFFECT: WHY WE BUY

Naming a problem gives you power over it. People feel better the moment a vague struggle gets a clean label, even before anything's actually fixed. Febreze coined "noseblind" and suddenly everyone was panic-sniffing their couch cushions. Snickers named the feeling "hangry." A consultant pitching generic marketing help loses, but the same consultant selling a "Content Paralysis Crusher" package closes. The companies that win aren't always the ones with the best product - they're the ones who named the thing their customer was already feeling but couldn't articulate.

NO DEFAULTS

No matter how obvious they appear, it's important to always question all assumptions. In many cases, what is known to be 'true' is only partially true, inaccurate, or simply the residue of a world that no longer exists. It's important to reexamine and reunderwrite your defaults from time to time. Carefully assess even those that seem to be working - these are the most dangerous, as most will not think to question them until it is too late.

STARTING A COMPANY AT THE BEGINNING OF THE EXPONENTIAL

A month-by-month account of a founder watching his moat evaporate in real time. November, two weeks of building replaces two months. December, a week becomes a day. January, a day becomes hours. February, a customer asks on a call why Claude can't just do the whole thing and nobody on the team has an answer. The useful part isn't the doom: it's noticing how quickly "we'll build it" stopped being a defensible answer.
