Bio

Most people who've come to me over the last four years didn't arrive with a brief. They arrived with a problem: "here's what's broken, can you help us figure it out?" That's the kind of call I like best. We start with the business problem, then work out what to fix first. Where I can help: - Paid acquisition that won't scale. I've run paid across Meta, Google, YouTube, TikTok and Reddit. At Rev.com, we grew net-new customers 34% while cutting CPA 30%. If your CAC keeps creeping up or a channel has stalled, we'll look at creative, audiences, bidding and the landing page behind it. - Marketplace growth. I spent four years at Thumbtack on both sides of a 300K+ provider marketplace, scaling customer acquisition 37% Y/Y and then leading supply-side growth. If you're balancing supply and demand, I've done it. - Measurement you can trust. A lot of spend decisions rest on platform-reported wins. I built incrementality testing at Thumbtack, and I'll help you set up attribution and lift tests so you know what's working before you put more money in. "I built it, now what?" If you shipped fast and now need to work out who it's for, we'll go through your ideal customer, your messaging and positioning, and how you stack up against competitors. Often the acquisition problem turns out to be a positioning problem. - AI in your marketing workflow. I've built agentic workflows that cut campaign time-to-market by 40%, including a Slack agent that analyzes paid performance every morning. I'll show you where AI saves time and where you still need human judgment. - Building and leading a growth team. I managed a team of 8 at Rev.com, and mentoring is what I've missed most while consulting. We can talk through hiring, testing culture, or helping the people you have grow. I've worked with everyone from two-person teams building their first website to Series C and enterprise B2B companies. Bring me the problem, and we'll figure out where to start.

Expertise

  • Growth marketing

    Bring me the growth number that's gone flat and we'll work back from it: paid, conversion, lifecycle, organic, and the measurement tying it together. I like the mix of creative and math, and I'll help you find the one place that's holding things back.

  • PPC strategies

    I started as a channel manager on Meta and have run paid across Google, YouTube, TikTok and Reddit. Bring your account or your plan and we'll look at structure, creative testing and bidding. At Rev.com that work grew new customers 34% while cutting CPA 30%.

  • Demand generation

    If leads are coming in but not turning into pipeline, I can help you find the leak. For one B2B SaaS client, rebuilding lead-to-SQL conversion and attribution cut cost per opportunity by 85%. We'll start with where your demand really comes from before deciding where budget goes.

  • Conversion rate optimisation

    I look at the whole path from ad to signup, so a channel never gets judged on its own. Bring your landing page or onboarding flow and we'll pick the tests worth running first. At Rev.com, reworking landing pages and onboarding lifted paid traffic conversion 55%.

  • Go to market strategy

    For the "I built it, now what?" moment. We'll work out who your ideal customer is, what to say to them and where to find them, before you spend on ads. A good fit for founders who shipped fast and now need a plan.

  • Product marketing

    Messaging, positioning, ICP and competitor work. When ads aren't landing, the message is often the problem, so we'll test how clearly you explain what you do and how you stand apart from the alternatives.

  • Artificial intelligence

    I build AI workflows for campaign optimisation, customer research, messaging and creative briefs, work that used to take weeks. I'll show you where AI saves real time in your marketing and where you still need a human call.

  • Building a team

    I led an in-house growth team of 8, and it's the part of the job I've missed most. Happy to talk through hiring your first growth person, setting up a testing culture, or helping the people on your team grow.

Toolkit

  • Meta Ads logo

    Meta Ads

    Meta is where I started and the platform I know best. Bring your account and we'll look at campaign structure, creative testing, and how to scale spend while still knowing what's working.

  • Google Ads logo

    Google Ads

    I've built and optimized Google Ads campaigns of all sizes (from hundreds a month to millions a month). I keep a strong focus on ROAS and optimizing dynamic inputs for the best possible results

  • Claude logo

    Claude

    I use Claude and Claude Code daily as core growth infrastructure. I've built a Slack agent that analyzes paid performance each morning, cutting time-to-insight from hours to minutes, plus LLM-driven creative testing workflows that generate and iterate ad variants at scale. Together these cut campaign time-to-market by 40% with no added headcount. I can help you build the same.

  • YouTube Ads logo

    YouTube Ads

    I've run YouTube as part of full-funnel paid programs at Rev.com and for consulting clients, alongside Meta, Google Search, and TV/CTV. I build creative testing roadmaps for video, match formats to funnel stage, and use incrementality and lift testing to measure YouTube's true impact beyond last-click. At Rev, this cross-channel approach helped grow net-new customers 34% while cutting CPA 30%.

  • MySQL logo

    MySQL

    I use SQL to pull and analyze my own data instead of waiting on analytics queues. I write queries for cohort analysis, CAC and LTV by channel, and funnel conversion, and use them to check platform-reported results against actual business outcomes. At Thumbtack, this work fed the LTV models we used to target high-value provider segments and lift provider activation 30%.

  • LinkedIn Ads logo

    LinkedIn Ads

    Reviewing resume claims against each listed consulting channel. I've used LinkedIn Ads for B2B demand generation, targeting by job title, company size, and industry to reach decision-makers. I focus on what happens after the click: lead quality, lead-to-SQL conversion, and cost per opportunity, not just CPL. For a B2B SaaS consulting client, I rebuilt funnel measurement and attribution to cut cost-per-opportunity 85%.

Industries

  • B2B

    A lot of my consulting has been with B2B companies, from early stage to Series C. I can help with paid acquisition, getting leads to turn into real pipeline, and the ICP and positioning work underneath it.

  • Marketplace

    I spent four years at Thumbtack growing both sides of a two-sided marketplace with 300K+ service providers. I scaled customer acquisition 37% Y/Y, then led supply-side growth, owning paid acquisition P&L and partnering with Analytics on LTV models that lifted provider activation 30%. I can help you balance supply and demand, set CAC targets by side, and grow without breaking liquidity.
