About
Yakir Hannan

11+ years in product growth across AI SaaS, fintech, cybersecurity, and AdTech. Based in Tel Aviv. I build growth engines for products that scale through self-serve adoption, not sales headcount.

My focus is the space between product and revenue, end to end: acquisition, activation, retention, and monetization, plus the analytics stack underneath. Lately that means agentic products: systems that act for the user, not just answer them. My work spans B2B SaaS and B2C at consumer scale, from Chargeflow and Workiz to ReasonLabs, where the product protected 10M+ daily active users across 180 countries.

From seed-stage startups to enterprise platforms at scale. I chase what moves metrics, not what fills slide decks.

Users at Scale

AI products have longer paths to value, higher trust barriers, and complex activation flows. I build the systems that solve that.

01

AI & Agentic Products

Taking AI products from concept to production. I define the use-case portfolio, design agentic architectures on MCP, and validate every scenario against live production data before release, so the model's answers stay grounded in what is actually true for each user. The evaluation suite is part of the product, not an afterthought. I build hands-on with LLMs and multi-agent systems.

Activation & Onboarding

Diagnosing and fixing the gap between signup and first value. AI products face unique activation challenges: trust in automation, time-to-value for ML-driven features, and complex setup flows. I map the entire journey from install to activation, identify where users drop off and why, then design and ship the flows that move them forward, whether the evaluator is a person or an agent.

03

Growth Architecture

Designing end-to-end PLG systems from metrics definition through execution. I build the infrastructure that connects product analytics, lifecycle emails, billing optimization, and attribution into one growth engine, so what acquisition spends and what the product does are measured against the same definitions instead of 2 disconnected systems that disagree at the end of the quarter.

Monetization & Billing

Billing is where growth meets revenue, and most product teams treat it as plumbing. I treat it as a product surface. I have owned billing and payments end to end across Stripe, Shopify Payments, and WooCommerce, restructured billing flows as activation levers, and built self-serve monetization tooling for SMB and enterprise motions alike. In the usage-pricing era the meter needs product thinking, and that is the work.

Product-Led Strategy

Translating business targets into product-driven growth plans. I define OKRs, build roadmaps, and align cross-functional teams around a single North Star metric. The goal is making the product the primary growth driver. Including the handoff most PLG companies get wrong: routing product-qualified accounts into a sales motion without breaking self-serve.

What I've built and shipped across AI-native B2B SaaS, fintech, cybersecurity, and AdTech.

I
AI Product, 0 to 1
Built the Chargeflow AI assistant from 0 to 1 on an MCP-based agentic architecture: an in-product analyst that answers each merchant's questions about their own account and recommends the next action. It takes repetitive questions off support and surfaces the right next product for each account, so it pays for itself on both sides of the ledger, and every answer is validated against live production data before release. Earlier, shipped Workiz Genius, an LLM assistant for call-recording insights that became one of the company's top sellers.

II
Product Growth Systems
Founded a cross-functional growth guild spanning product, marketing, CX, and analytics, to run growth as one operating system instead of 4 separate functions. 11+ years driving product growth across B2B SaaS, adtech, marketplaces, and consumer platforms, owning the roadmap and the metrics in each. Built the flagship SSP platform at Tremor International, now Nexxen, from concept to production.

III
Growth at 10M+ User Scale
Owned growth for endpoint and mobile at ReasonLabs, a B2C cybersecurity platform protecting 10M+ daily active users across 180 countries. Owned conversion and cross-sell strategy, shipped predictive ML features that detect threats by behavior, and ran experiments at 50,000 to 100,000 users per variant, which is the scale where a result is believable rather than suggestive.

IV
Activation for AI Products
Redesigned signup-to-activation funnels at Chargeflow, a B2B AI chargeback automation platform serving 20,000+ merchants, where users must trust automated decisions. Rebuilt self-serve signup and onboarding with unified auth and integration-specific paths, taking activation to its highest point since launch. Drove the launch and the virality work behind Prevent, a real-time fraud-prevention product that took Product of the Day on Product Hunt.

V
Enterprise Platform & Product-Led Sales
Turned enterprise commitments sold ahead of build into shipped platform capabilities at Chargeflow, and built the routing that qualifies self-serve signups into an enterprise pipeline. Earlier, built self-serve monetization tooling at Tremor International, now Nexxen, whose SSP held exclusive outstream video rights across 50+ News Corp titles in 3 markets including The Times and The Wall Street Journal, scaling into $1M+ in daily revenue.

VI
Growth Metrics & Operating Cadence
Designed North Star metric frameworks adopted across product, sales, CS, and executive teams. Built weekly reporting cadences that replaced reactive decision-making with structured prioritization based on what moves revenue.

Start 10,000 people at the top. At 50% a step, 313 reach the far end still paying.

Why that beats one big redesign

Writing about what I've learned building growth systems for AI products and agentic systems.

Unit Economics

The Free Tier Meets the Inference Bill

Free was a marketing expense that rounded to zero, until every action acquired a model call behind it. Free moved from duration to quantity, and now it needs a budget and a conversion job.

Monetization

Pricing After Seats: What Growth Teams Own Now

The human seat was the unit of SaaS pricing for 2 decades. Agents broke it. When the unit of work detaches from the unit of pricing, the pricing page becomes a product surface.

AI Product Craft

Evals Are the New QA

Every AI product works in the demo. Production is a stranger asking about their own data. The scenario library is the new PRD, production data is the only honest test set, and the eval suite belongs in the release path.

Agentic Growth

The Agentic Growth Team

Agents already run the middle of the experiment loop. What breaks when they do, what humans keep, and why the metric definition is now the highest-leverage artifact on the team.

AI-Led Growth

AI-Led Growth: The Motion After Product-Led

Half the industry says PLG is dead because the next user is an agent. Both sides argue about the wrong layer. The economics survive, the funnel's assumptions die, and the build list is the same either way.

Agent-First Growth

When Your Next User Is an Agent

A person who hits friction retries tomorrow. An agent fails silently and takes the next tool in the registry. 3 kinds of users now move through the funnel, and each needs its own definition of activated.

AI Adoption

Production Is an Org Problem

Almost every company has an agent pilot. Far fewer have one in production. The surveys disagree on the spread and agree on the causes, and model quality is not among them.

Agentic Commerce

Friction Was Doing a Job

In-assistant buying removed every step between intent and purchase, and converted worse than sending the shopper to the merchant. The steps that got deleted were carrying the decision.

Outcome Pricing

When Resolved Becomes a Price

Bill per resolved outcome and the rubric deciding what counts as resolved stops being a quality artifact. It becomes the billing engine, and an eval failure becomes an invoice that never goes out.

AI Product Growth

The AI Trust Gap: Why Traditional Onboarding Fails AI Products

AI automation asks users to trust a black box with real business outcomes. That trust gap creates activation friction traditional SaaS onboarding patterns cannot solve. What works instead.

AI Disclosure

The Transparency Tax

Disclosing chatbot identity before a sales conversation cut purchase rates by 79.7% in a field experiment. The timing fix that recovered it is what Article 50 of the EU AI Act removed on 2 August 2026.

Switching Costs

The Moat That Exported Itself

Every deck calls memory the last AI moat. Then the 3 companies with the most of it to protect all shipped memory portability inside a month. Whatever survives a plain-language export was never a switching cost.

Marketplace Growth

Time to First Dollar

A marketplace has 2 activation problems running on different clocks. Supply activates on first earning, demand on first satisfying transaction, and referral loops built before either one works amplify churn.

Growth Measurement

Attribution After the Click

Discovery moved inside LLM answers, where the click never fires. Share of answer replaces share of shelf, branded search becomes the shadow of invisible recommendations, and some influence is now honestly unmeasurable.

Distribution

Distribution Is a Product Skill Now

The best product no longer wins by default. Building got cheap, discovery compressed into AI answers, and owned audience became an asset a product team has to build on purpose.

Growth Infrastructure

Growth Runs on the Warehouse Now

Every tool in the old growth stack kept its own copy of the customer, with its own definitions. The copies are dying, and the team that runs on the warehouse owns definitions instead of tools.

Enterprise Growth

Going Enterprise Without Killing Self-Serve

Moving upmarket is usually framed as outgrowing self-serve. Backwards. Self-serve is the qualification engine the enterprise motion runs on, and the handoff decides whether you capture the deal.

B2B Onboarding

The Buyer, the Admin, and the User

The flow is designed for 1 person and 3 different people show up, each with a different definition of value. Detect the persona at entry, branch the first session, treat activation as a chain.

Growth Metrics

Metrics That Move Teams, Not Just Dashboards

Most product dashboards measure what is easy to count. The metrics that change behavior are the ones a PM, designer, and R&D lead can argue about in the same room.

Retention

Building Retention Before You Need It

Churn is a receipt, not an event. Retention is an instrumentation problem long before it is an analysis problem, and the cancellation flow is the highest-signal surface most products waste.

Funnel Optimization

The Compound Effect of Small Funnel Fixes

Growth teams chase 10% wins and miss the ones that compound. A 5% lift in 3 places does more for ARR than a single redesign, and it ships in a week.
