Introduction

Growth hacking is a fast, experiment-driven approach to finding reliable ways to grow a business. Instead of committing big budgets to a single plan, you run many small, low-risk tests landing pages, referral nudges, onboarding tweaks to see what moves leads, revenue or retention. Keep the winners, drop the losers, and repeat. It is less about tricks and more about systematic experimentation.

Why it matters

Growth hacking matters because conventional marketing channels become increasingly expensive and competitive as more companies pursue them, whilst creative alternatives often remain underexploited and disproportionately effective. When LinkedIn ads targeting CFOs cost £15 per click, the company that discovers a viral growth loop or strategic integration can acquire customers at fraction of competitors' costs, gaining decisive advantage. This efficiency particularly benefits resource-constrained organisations early-stage companies, bootstrapped firms, challenger brands that cannot outspend established players but can out-innovate them. Beyond cost savings, growth hacking builds a culture of experimentation that accelerates learning velocity: teams running ten experiments monthly discover what resonates 10x faster than those pontificating endlessly about single big campaigns. Research on breakout growth companies reveals they frequently deployed creative, unconventional tactics during early scaling rather than simply executing standard playbooks better. The methodology also creates compounding advantages: each successful experiment generates insights applicable beyond that specific test, building institutional knowledge competitors cannot easily copy. However, growth hacking requires discipline the temptation is chasing clever tricks rather than sustainable systems. Organisations that succeed treat growth hacking as systematic hypothesis testing, not random tactic generation, documenting failures as rigorously as wins to prevent repeated mistakes.

How to apply it

Growth hacking for B2B agencies and consultancies

Start with simple, resource-light tests that fit client-facing workloads.

  1. Turn your most popular blog post into a one-page PDF checklist and gate it for email addresses.
  2. Send a personal Loom video follow-up to every proposal within 24 hours.
  3. Add a referral line to client invoices offering a free strategy hour for introductions.
  4. Insert a dynamic case-study block in outreach emails that swaps based on industry tag.
  5. Host a quarterly live audit webinar and invite prospects to submit their site for review.
  6. Offer a one-week paid discovery sprint at a fixed price to lower commitment friction.
  7. Add a simple exit-intent pop-up on the blog asking visitors to book a fifteen-minute call.
  8. Re-share every LinkedIn post as a carousel with key metrics highlighted for higher engagement.
  9. Automate proposal follow-ups with a three-email sequence triggered when a deal is idle for five days.
  10. Publish a public roadmap of upcoming service add-ons to spark early interest and feedback.

Growth hacking for B2B SaaS companies

Focus on product touch-points and user referrals.

  1. Shorten the free-trial sign-up form to name and email only; capture extra data after activation.
  2. Trigger an in-app tooltip highlighting one hidden feature per day for new users.
  3. Offer an annual-billing discount during the first seven days of the trial.
  4. Add a one-click Slack invite inside the app so users can bring colleagues.
  5. Launch a referral banner that rewards account credits for every invited user who activates.
  6. Send a usage milestone email (e.g. ‘You saved 100 hours’) that includes a social share link.
  7. Create a public changelog with a subscribe option to keep leads warm before they buy.
  8. Auto-generate a personalised onboarding video using the user’s name and company logo.
  9. Detect inactive accounts at day ten and trigger an automated concierge call offer.
  10. Add a pricing-page FAQ accordion answering the top five objections gathered from support tickets.

Growth hacking for B2B e-commerce and wholesale platforms

Use on-site tweaks and post-purchase loops to drive repeat orders.

  1. Display real-time stock levels to create urgency on popular SKUs.
  2. Offer volume-based discounts that unlock automatically in the basket.
  3. Add a reorder button in account dashboards showing previously purchased bundles.
  4. Trigger a cross-sell email three days after dispatch, suggesting complementary products.
  5. Include a printed insert in every parcel with a QR code linking to a feedback survey for a discount.
  6. Run a monthly ‘buyers club’ webinar previewing new inventory for registered customers.
  7. Place a sticky banner for free shipping thresholds visible during the entire checkout.
  8. Offer Net 30 terms instantly via a credit partner to reduce friction for first-time buyers.
  9. Use exit-intent pop-ups on product pages to offer a PDF spec sheet in exchange for email.
  10. Create a points-based loyalty programme that rewards both order value and review submissions.

These straightforward hacks keep risk low while uncovering what truly accelerates growth for each business model. Test, measure, adopt what works, and move on to the next idea.
