Designing a 2026 growth engine: from one‐off campaigns to compounding growth loops

Read time: 3 minutes.

Welcome to the 193rd edition of The Growth Elements Newsletter. Every Monday and sometimes on Thursday, I write an essay on growth metrics & experiments and business case studies.

Today’s piece is for 8,000+ founders, operators, and leaders from businesses such as Shopify, Google, Hubspot, Zoho, Freshworks, Servcorp, Zomato, Postman, Razorpay and Zoom.

Today’s The Growth Elements (TGE) is brought to you by:

How AI Will Actually Change CX in 2026

Most CX leaders agree AI is the future — fewer agree on what actually changes next.

This guide distills six concrete predictions shaping customer experience in 2026, from agentic AI and AI operations to real-time CX experimentation.

Built for enterprise teams navigating scale, complexity, and accountability — not hype.

[1] Funnels vs loops: define the system

• Funnels move prospects from A → B → C and then stop; they’re useful for diagnosis, but not as the core growth model.

• Growth loops feed outputs back into inputs: one customer or action increases the chance of another (eg: content → subscribers → referrals → more reach → more customers).

Your goal is to design a single primary loop for your stage and ICP.

[2] Three canonical B2B SaaS loops in 2026

1. Content/community loop:

   • Content → audience → trust → inbound pipeline → more customer stories → better content.

2. Product usage → advocacy loop:

   • Activation → habit → outcomes → reviews/case studies/referrals → more high‑intent leads.

3. Partner/eco loop:

   • Integrations/partners → shared customers → co‑marketing → more exposure → more integrations.

Pick one as the backbone; others can layer later.

[3] Build your loop

For one chosen loop, define:

• Input:

  • Where does “energy” first enter? (eg: weekly newsletter, free tool, integration.)

• Core actions:

  • What must users do for the loop to work? (Subscribe, share, invite, review, integrate.)

• Output:

  • What compounding asset do you get? (Audience, content, social proof, data, distribution.)

• Metrics:

  • 2-3 KPIs (eg: subscriber growth, invite rate, review volume, partner‑sourced pipeline %).

If any arrow is weak (eg, users don’t share, partners don’t co‑market), that’s where you intervene.

[4] Plug performance marketing into the loop (not next to it)

1. Use paid to accelerate parts of the loop, not as a separate silo:

   • Promote the best content to target the ICP to grow the audience.

   • Boost proof (case‑study ads, review ads) to audiences already aware of you.

2. Measure paid on its contribution to loop health (subscribers, trials from core ICP, community growth), not just last‑click conversions.

[5] Operating model: make it a real “engine”

1. Weekly:

   • Review loop metrics (inputs, key actions, outputs), decide 1-2 changes or experiments.

2. Monthly:

   • Reassess loop design. Are you still running “campaigns,” or do outputs clearly feed new inputs?

3. Ownership:

   • One person owns the loop end‑to‑end (not just channels), with cross‑functional support from product, sales, and CS.

Final learnings

• Campaigns create spikes; loops create compounding baselines that get easier to grow over time.

• The winners in 2026 are not those with the best isolated tactics, but those with one clear, well‑operated growth loop that performance marketing and product both reinforce.​

That's it for today's article! I hope you found this essay insightful.
