The Two-Bucket Rule: Why Most Funded Startups Still Go Broke
How Top Founders Use the 70/30 Rule to Extend Runway and Drive Growth
In 2008, Brian Chesky was sleeping on an air mattress in his apartment, selling cereal boxes to stay afloat. Airbnb had $200 left in the bank. His co-founder Joe Gebbia wanted to hire a PR firm—$5,000 for “real media coverage.” Brian said no. Instead, they spent $178 on a better camera for listings. That decision—choosing product over polish—added three months to their runway. Those three months got them into Y Combinator. The rest is a $75 billion story.
Curiosity Teaser
Most early-stage startups die from distraction, not starvation. They hire too early, build unnecessary infrastructure, and optimize irrelevant problems. The question isn’t whether you have enough money, but if you’re spending it on the only two things that matter: making something people want and getting it in front of them.
Narrative Burst #1: The Fallacy of “Real Company” Spending
There’s a misleading belief founders tell themselves: “We need to look like a real company.”
They lease office space, hire an executive assistant, pay for Slack Enterprise, commission a brand refresh, and buy standing desks. The burn rate climbs from 8K to 28K monthly, and six months of runway becomes two.
Here’s what happened: you confused professionalism with advancement.
Patrick Collison, Stripe’s CEO, ran the company from a tiny apartment until they had millions in revenue. Drew Houston coded Dropbox alone for a year before hiring anyone. Paul Graham’s rule was straightforward: “Make something people want, then figure out everything else.”
Every dollar spent on “looking legit” is a dollar not spent on the only two things that keep startups alive: Product (making something better) and Go-to-Market (putting it in front of buyers). Everything else—HR systems, corporate cards, team offsites, fancy tools—are luxuries earned with revenue, not expenses justified with optimism.
Founder Takeaway #1: Postpone any cost that doesn’t directly improve your product or acquire customers until revenue makes it trivial.
Narrative Burst #2: The Compounding Cost of Premature Infrastructure
Jake, a founder I advised, raised $800K. Within four months, he hired a head of operations, a finance manager, and a “culture lead.” His reasoning? “We’re building for growth.”
Eight months later, he had 12 employees, $90K in MRR, and three months of cash left. The operations head built dashboards no one used. The finance manager optimized a struggling budget. The culture lead planned offsites for a team that should’ve been selling.
Meanwhile, his competitor—same space, same funding—had three people: a founder, a founder, and one engineer. They hit $200K MRR in the same timeframe. When Jake’s company folded, his competitor hired his best engineer.
The difference? Jake funded infrastructure, while his competitor funded growth.
Sequoia’s advice translates to “Default alive, not default dead.” Spend like every dollar could be your last, because it might be. CB Insights shows 29% of startups fail because they run out of cash—not due to lack of opportunity, but because they spend on tomorrow’s problems instead of today’s survival.
Founder Takeaway #2: Hire and spend for your current revenue, not projected revenue. Scale follows traction; never the opposite.
Cross-Disciplinary Lens: The Farmer’s Maxim
Ancient Roman farmers had a principle: Primum vivere, deinde philosophari—first survive, then philosophize.
You don’t plant olive groves when the wheat harvest is failing. You don’t build a barn with three chickens. You focus on what sustains you now, and once you’re secure, invest in what sustains you later.
Startups operate the same way. Your wheat—product and GTM—generate the revenue that keeps you alive. Everything else—legal infrastructure, HR policies, analytics, optimization—are olive groves. Beautiful, valuable, worth having. But only after you’ve survived.
Botanists call this “apical dominance.” The main shoot suppresses side growth until it’s strong enough to support branches. Your startup works identically. The main shoot is revenue generation. Premature branching (team expansion, operational complexity, tooling sprawl) undermines the core.
Biology teaches that organisms in resource-scarce environments develop efficiency. Desert plants don’t waste water on decorative leaves. Early-stage startups shouldn’t spend capital on decorative roles.
Try This Today: Open your bank statement. Highlight every expense from the last 30 days. Ask: “Did this directly improve our product or get us customers?” If no, cancel or pause it. You’ll save 15–30% of your burn in under 30 minutes.
Toolkit: The Two-Bucket Audit
Run this monthly review to maintain discipline:
1. Classify Every Expense List each cost under three categories: • Bucket A (Product): Engineers, design tools, hosting, product contractors, user research • Bucket B (Go-to-Market): Sales salaries, ads, events, content creation, outbound tools, partnerships • Bucket C (Everything Else): Office, admin, legal, HR, finance, unrelated software
2. Calculate Your “Focus Ratio” Formula: (Bucket A + Bucket B) ÷ Total Spend × 100
Aim for 70–85% at pre-PMF stage and 60–75% at early PMF. If you’re below 60%, you’re funding distractions.
3. Apply the “Revenue Test” For every Bucket C item, ask: “If we paused this for 90 days, would revenue drop?” If no, pause it.
4. Reallocate Aggressively Take 50% of Bucket C savings and split them: 70% to GTM experiments, 30% to product improvements. Run this each quarter.
5. Track Weeks of Runway per Dollar Divide remaining cash by weekly burn. Every $1,000 saved = X more days alive. Make it impactful. Print it. Display it daily.
Startups don’t fail from thinking too small. They fail from spending too much.
Your job isn’t to build a “real company,” but a profitable one. Everything that doesn’t serve product or distribution is a luxury you haven’t earned yet. The founders who survive aren’t the ones with the best office or biggest team, but those focused on the two buckets that fill themselves: making something worth buying and getting people to buy it.
24-Hour Challenge: Within a day, cancel one subscription, pause one non-essential service, or defer one “nice-to-have” hire. Use the saved money for a GTM experiment—new ad channel, cold email campaign, or customer interview session. Experience the difference between spending on someday and today.

The Airbnb story perfectly ilustrates how discipline is more valuabe than capital in early stages. The 70/30 rule feels counterintuitive because most founders think they need to 'look profesional' to atract customers, when actually customers just want a product that solves their problem. Those three extra months of runway literally changed everything.
Great post. +1 to everything.
