This book (by Gabriel Weinberg and Justin Mares) is for startup founders and marketers looking for practical strategies to acquire customers and grow their user base. It explores 19 different marketing channels and helps identify the best ones for a given product.
In Traction: A Startup Guide to Getting Customers, Gabriel Weinberg and Justin Mares provide a comprehensive playbook for startups seeking growth. The book emphasises that traction—evident growth in metrics like revenue, user base, or downloads—is the most critical determinant of a startup’s success. Through interviews with over 40 founders and research into numerous startups, the authors identify and break down 19 key marketing and distribution channels that companies can use to acquire customers and scale effectively.
1. The Importance of TractionTraction is described as the lifeblood of startups, providing validation that the business is working and helping unlock opportunities such as fundraising, partnerships, and hiring. A startup’s primary goal is to grow, and traction provides the quantitative evidence of that growth.
2. The Bullseye Framework
The Bullseye Framework is a systematic approach for identifying the most effective marketing channel for your startup at any given time. It consists of five steps:
3. Traction Thinking
Startups should spend 50% of their time on product development and 50% on traction efforts. This dual focus ensures startups avoid the “product trap,” where founders assume that a great product will naturally attract users without strategic marketing.
The authors outline 19 channels through which startups can gain traction. Each channel is illustrated with case studies and expert insights:
Each channel is backed by real-world examples. For instance, Dropbox’s referral program, which rewarded users with additional storage for inviting others, is highlighted as a successful use of viral marketing.
Critical Path and IterationThe book stresses the importance of defining a critical path—a clear series of milestones to reach your traction goals. After identifying the most promising traction channel, startups should continuously optimise their efforts and pivot to new channels as needed.
Traction offers actionable insights and frameworks for systematically growing a startup, making it an essential guide for entrepreneurs aiming to scale their businesses effectively.

Most B2B marketers are either Random Ricks (trying everything) or Specialist Steves (obsessed with one channel). Generalists run tactics without strategy. Specialists hit channel ceilings. But there's a better way.

Tries everything at once. Posts on LinkedIn, runs ads, tweaks the website, chases referrals. Nothing compounds because nothing's consistent. Growth feels chaotic.

Obsessed with one tactic. 'We just need better ads' or 'SEO will fix everything.' Ignores the rest of the system. One strong engine can't carry a broken machine.
