A startup is a company designed to grow fast by searching for a repeatable, scalable business model.
Key points
- Paul Graham defines a startup as a company designed to grow fast; being newly founded is not enough [1].
- Steve Blank describes a startup as a temporary organization designed to search for a repeatable and scalable business model [2].
- Graham cites 5 to 7% growth a week as a good rate during Y Combinator, and 10% a week as exceptional [1].
- Paul Graham notes that most companies able to grow fast find outside money helps them grow faster, but he also argues that reaching profitability puts founders in a stronger position, and some startups choose Bootstrapping instead [4].
- The early priority is Product-Market Fit; scaling a Go-to-Market (GTM) Strategy before fit tends to waste capital [3].
What makes a company a startup
Age and size do not define a startup; intent does. Paul Graham's essay Startup = Growth argues that a barbershop is not designed to grow fast, while a search engine is, and that this design for growth is what the word startup captures [1]. Steve Blank adds an operational view: large companies execute a known business model, while startups are still searching for one, testing assumptions about customers, channels and pricing [2]. That search is why startups run Customer Discovery, sell through Founder-Led Sales and change direction often. Wikipedia notes that startups typically face high uncertainty and failure rates, and that many are in technology because software can reach large markets with low marginal cost [3]. Many of today's startups are B2B SaaS companies.
Funding and growth
Startups usually spend ahead of revenue, so funding shapes their options. Many raise venture capital in stages, trading equity for money to grow faster than revenue alone would allow; Paul Graham describes a small first round, a larger round to build the company, and later rounds to accelerate growth once it is clearly succeeding [4]. Others grow through Bootstrapping, funding themselves from customer revenue. In both cases, investors and founders watch growth rate, burn rate and Unit Economics such as Customer Acquisition Cost (CAC) and Customer Lifetime Value (LTV). Graham's benchmark of 5 to 7% weekly growth during Y Combinator shows how aggressive expectations can be [1]. Funding rounds are also a common Trigger Event for outreach, because newly funded companies often hire and buy tools soon after closing a round.
Startups as buyers
Startups are attractive customers for many B2B products. They make decisions in small teams, adopt new tools quickly and are often Early Adopters willing to try unproven vendors. Their needs also change fast as they grow, which creates regular buying moments around new hires, new markets or a change in tech stack. The trade-offs are smaller budgets, higher Churn Rate and the risk that a customer runs out of money. Sellers targeting startups usually define their Ideal Customer Profile (ICP) by stage, team size and funding, then reach out with short, relevant emails that respect the founder's time. Qualifying on these traits up front, through Lead Scoring and clear Disqualification rules, keeps outreach focused on companies that can actually buy.
