Best growth hacking tools (2026): what we run, and which hacks still work in B2B

Growth hacking tools are the scrapers, automation platforms, analytics products and referral engines a small team uses to get the output of a much bigger one. For a B2B startup the useful ones fall into three jobs: finding and reaching buyers before anyone else does, wiring tools together so nothing waits on a human, and measuring which experiments actually moved signups or pipeline.

Below is the stack OneGTM runs for its own pipeline and its clients, then the automation, analytics, experiment and referral tools worth knowing, with what each vendor publishes about price. Some links are referral links that may earn us a credit, which never changes what you pay or who is listed. Most hacks stop working once everyone copies them, so the section on what still works in 2026 matters more than the tool picks.

Key takeaways

  • We run Claude Code, Deepline, Apify and PhantomBuster for scraping, enrichment and outbound automation.
  • Zapier, n8n and Make glue tools together. n8n is the cheapest at volume if you can self-host it.
  • PostHog and Mixpanel both give you 1M product events a month free, which covers most early startups.
  • Referral tools like Viral Loops and GrowSurf only work when the product already has users who like it.
  • The hacks that still work in B2B are fast reactions to buying signals. Spray and pray volume burns domains.

The growth stack OneGTM runs

Claude Code writes and runs the scripts, Deepline handles enrichment and scheduled plays, and Apify and PhantomBuster scrape the public data Deepline does not cover, such as who engaged with a competitor's LinkedIn post. See how we wire it together in Claude Code for GTM.

Claude Code

OneGTM uses this

Anthropic's coding agent in the terminal. We use it to build scrapers, enrichment scripts, list cleanup jobs and landing page tests in hours, then keep them in a git repo the client owns.

Best for: Building custom growth tooling without an engineering team

Pricing: Included in Claude Pro ($20/month, or $17/month billed annually) and Max from $100/month.

Deepline

OneGTM uses this

GTM data and orchestration layer you drive from a CLI or Claude Code. It routes enrichment across dozens of providers, runs scheduled plays and live monitors, and pushes results to the CRM and sequencers.

Best for: Enrichment waterfalls and signal plays as code

Pricing: Pay as you go at $0 platform fee plus usage at $0.10 per credit, with up to 15 scheduled plays and monitors. No per-seat charge.

Apify

OneGTM uses this

Marketplace of ready-made scrapers (actors) for LinkedIn, Google Maps, job boards, review sites and almost anything else public, plus the infrastructure to run your own on a schedule.

Best for: Scraping public data at scale for list building

Pricing: Free plan with $5 of usage a month; Starter $19/month, Scale $199/month, Business $999/month, each including the same amount in usage. 10% off billed annually.

PhantomBuster

OneGTM uses this

Cloud automations (Phantoms) that extract LinkedIn and social data and chain them into workflows, such as pulling everyone who engaged with a post and exporting them to a CRM. We still use it for LinkedIn engagement scraping.

Best for: No-code LinkedIn and social scraping workflows

Pricing: Start $56/month, Grow $128/month, Scale $352/month billed annually (20% off monthly pricing). Plans differ by automation slots, execution hours and email credits.

Automation, scraping and signal tools

These connect the rest of your stack and turn raw data into lists. Pick one automation platform and stick with it. Running Zapier and Make side by side is how workflows break without anyone noticing.

Zapier

The default no-code automation platform, with the biggest app directory. Good for simple triggers like new form fill to CRM to Slack, and expensive once you run thousands of tasks.

Best for: Non-technical teams wiring common SaaS apps

Pricing: Free with 100 tasks a month. Professional from $19.99/month billed annually ($29.99 monthly) for 750 tasks. Team from $69/month billed annually for 2,000 tasks. Enterprise custom.

n8n

Workflow automation you can self-host, with code steps and AI agent nodes. Prices by workflow execution, so a long workflow costs the same as a short one.

Best for: Technical teams running high-volume workflows cheaply

Pricing: Self-hosted community edition available free on GitHub. Cloud Starter EUR 20/month and Pro EUR 50/month billed annually (2,500 and 10,000 executions). Business EUR 667/month self-hosted. Enterprise custom.

Make

Visual automation builder with branching, routers and data stores, cheaper per operation than Zapier for most multi-step scenarios.

Best for: Complex visual workflows on a small budget

Pricing: Free plan with 1,000 credits a month. Core, Pro and Teams plans are priced by monthly credit volume, with a discount for annual billing. Startups under 20 employees may get 50% off Business.

Clay

OneGTM has used this

Spreadsheet-style enrichment and research tool that pulls from many data providers and runs AI research columns on each row. We built client tables in it before moving new builds to Deepline and Claude Code.

Best for: Point-and-click enrichment and account research

Pricing: Free plan with 100 data credits a month. Launch from $167/month and Growth from $446/month billed annually, priced by actions and data credits. Enterprise custom.

RB2B

OneGTM has used this

Identifies US individuals visiting your website and posts them to Slack or your CRM, so you can reach out the same day someone reads your pricing page.

Best for: Turning anonymous site traffic into named leads

Pricing: Free with 150 resolutions a month. Starter $79/month for 300. Pro from $149/month. Pro+ from $199/month.

Product analytics, experiments and referral loops

These matter once people are signing up. Analytics tells you where they drop, experiment tools tell you whether a change helped, and referral tools turn happy users into a channel.

PostHog

Product analytics, session replay, feature flags, A/B tests and surveys in one product, with a free allowance that resets every month and usage pricing after it.

Best for: Startups that want analytics and experiments from one vendor

Pricing: Free every month: 1M analytics events, 5,000 session recordings, 1M feature flag requests and 1,500 survey responses. Usage-based pricing above that, for example web recordings from $0.005 each past 5,000.

Mixpanel

Event-based product analytics for funnels, retention and cohorts. The free plan is generous and Growth is priced only on event volume.

Best for: Funnel and retention analysis for SaaS

Pricing: Free up to 1M events a month. Growth is free for the first 1M events, then $100/month billed annually for 1.5M and $840/month billed annually for 10M. Enterprise custom. Startup program gives the first year free if eligible.

GrowthBook

Open source feature flags and A/B testing that reads results straight from your data warehouse, so experiment numbers match the rest of your reporting.

Best for: Running A/B tests on your own data

Pricing: Open source self-hosted plan free with unlimited users. Cloud Starter free for up to 3 users. Pro $40 per seat per month. Enterprise custom.

Viral Loops

Templates for waitlists, giveaways, newsletter referrals and customer referral programs, installed with a snippet of JavaScript.

Best for: Prelaunch waitlists and newsletter referrals

Pricing: Billed annually: Start-up $35/month (1,000 participants), Plus $99/month (5,000), Growing $159/month (10,000), Power $279/month (25,000). Enterprise custom. 14-day free trial.

GrowSurf

Referral and affiliate program software aimed at B2B and SaaS, with fraud checks and rewards tracked through the signup and payment flow.

Best for: Customer referral programs for SaaS

Pricing: Startup plan for up to 5,000 participants (price not listed). Business $449/month for up to 10,000 participants. Custom pricing above 150,000. 14-day free trial.

Prices are from each vendor's site as of October 2026 and change often, so check before you buy. This is an opinionated list, not a paid ranking. Some links are referral links that may earn us a credit; that never changes what you pay or who makes the list.

Which growth hacks still work in B2B in 2026

Every hack has a half-life. Once a tactic shows up in a LinkedIn carousel, buyers have seen it fifty times and it stops working. What lasts is speed and relevance: reaching the right person within a day of a real signal, with a message that proves you noticed.

The ones we see working right now all start with public data and end with a fast, specific message. Our lead generation strategies page goes deeper on each.

  • Scrape everyone who comments on a competitor's or influencer's LinkedIn post, filter them against your ICP, and message them within 48 hours.
  • Identify website visitors and email the ones who hit your pricing or comparison pages the same day.
  • Watch job posts for the role your product replaces or supports, and reach the hiring manager.
  • Build free tools (calculators, graders, checkers) that rank in search and collect emails from people with the exact problem.
  • Add a referral loop only after users already recommend you without being asked.

How to choose growth hacking tools

Start with the bottleneck. If you do not have enough of the right people to talk to, buy scraping and enrichment first. If people sign up and leave, buy analytics. If you have happy users and no word of mouth, try a referral program. Buying all three on day one just adds logins.

Then decide who will run it. No-code tools like Zapier, PhantomBuster and Clay are fast to start and get expensive at volume. Code-first tools like n8n, Apify and Deepline are cheaper per run and need someone comfortable with scripts, which Claude Code now makes far easier for a non-engineer.

  • Check what each plan charges per task, credit, event or participant, then model your real monthly volume.
  • Make sure the tool can push results to your CRM or sequencer without a manual export.
  • Prefer tools with an API or MCP server so you can script them later.
  • Pick one automation platform and one analytics tool. Two of either creates conflicting numbers.

Pitfalls that kill growth hacks

Most failed growth experiments die in execution. Watch for these.

  • Burning your main domain with high-volume cold email. Send from separate domains and warm them first.
  • Scraping LinkedIn from your own account at high volume and getting it restricted.
  • Running tests without enough traffic to reach significance, then shipping the noise.
  • Building on a vendor that disappears. Trigify announced it was joining HubSpot and shut off its standalone platform for standard customers on 22 October 2026, so keep your data and logic somewhere you own.
  • Tracking vanity numbers like list size and open rates instead of meetings booked and pipeline.

When to get help with growth tooling

Signing up for tools takes an afternoon. The hard part is wiring scraping, enrichment, scoring and outreach into one loop that runs every day without breaking, and knowing which signals are worth acting on for your market.

OneGTM builds that loop on Claude Code and Deepline, with Apify and PhantomBuster for the scraping and Instantly and HeyReach for outreach. You own the code, the data and the accounts.

  • You have five growth tools and no idea which one produced your last ten meetings.
  • Your Zapier bill grows faster than your pipeline.
  • You want to act on competitor engagement, website visits or hiring signals and nobody has time to build it.
  • You tried a growth hack once, it worked for a month, and it has not been rerun since.

Growth hacking tools FAQ

What are the best growth hacking tools for B2B startups?
The best growth hacking tools for a B2B startup are a scraper (Apify or PhantomBuster), an enrichment layer (Deepline or Clay), one automation platform (Zapier, n8n or Make) and one product analytics tool (PostHog or Mixpanel). OneGTM runs Claude Code, Deepline, Apify and PhantomBuster for its own pipeline. Add a referral tool like Viral Loops or GrowSurf once users already recommend you.
Are there free growth hacking tools?
Yes. PostHog and Mixpanel are free up to 1M events a month, n8n and GrowthBook are free to self-host, Zapier has a free plan with 100 tasks a month, Apify includes $5 of free usage a month, and RB2B identifies up to 150 website visitors a month for free.
What is the difference between growth hacking and growth marketing?
Growth hacking is fast, cheap experimentation to find a channel or tactic that works, usually built with scrapers, automation and small tests. Growth marketing is the longer-term work of scaling the channels that proved out, with budget, content and process behind them. Most startups do the first until something works, then switch to the second.
Is scraping LinkedIn for growth hacking legal?
Scraping publicly visible data has generally been treated as lawful in the US, but it can still break LinkedIn's terms of service and get accounts restricted, and GDPR applies to data on people in Europe. Tools like Apify and PhantomBuster limit risk by pacing requests, and you should only collect what you need. This is not legal advice.
Should I use Zapier, Make or n8n?
Use Zapier if non-technical people will build the automations and volume is low. Use Make if you want complex visual workflows for less money per operation. Use n8n if someone technical can self-host it, since you pay per workflow execution rather than per step and the community edition is free.
Can Claude Code replace growth hacking tools?
Claude Code can replace a lot of the glue work, such as writing scrapers, cleaning lists, calling enrichment APIs and building small landing page tests. It does not replace data sources or sending infrastructure, so you still need tools like Apify, Deepline, Instantly and an analytics product. OneGTM uses Claude Code to build and run the scripts that tie those together.
What growth hacks still work in B2B?
The B2B growth hacks that still work are fast reactions to public buying signals: messaging people who engaged with a competitor's LinkedIn post, reaching website visitors who viewed pricing, contacting hiring managers posting relevant jobs, and free tools that rank in search. High-volume generic cold email has mostly stopped working.
