Services
A growth team that already knows what to ship on Monday.
Problem we solve
Most businesses get to a point where they need senior growth firepower but can't justify a full hire. Or they have a growth lead and need backup in specific lanes without diluting them.
The market answer is usually a generalist agency that ships impressions, or a freelancer who's brilliant in one channel and silent everywhere else.
We are the third option. A senior team that runs your acquisition, CRM and conversion as if we worked there, contracted as if we did not.
Part 1
Three services, described in plain English. The technical detail sits underneath each one for anyone who wants it.
Paid ads
Meta, Google, TikTok and LinkedIn ads planned, built, run and improved every week, with tracking that shows which ads actually bring in sales.
The detail
Identify the bottleneck. Concentrate spend there. Most breakouts come from one channel finally working, not five at half power.
We run weekly experiments. Every week's result informs the next week's brief. You always know what's live and why.
Server-side CAPI, proper deduplication, dashboards that report contribution margin and payback period instead of vanity ROAS.
We use Veo, Imagen, Gemini and HeyGen to produce static and video variants at ten times the volume a traditional agency can ship. We test them properly in market.
Meta, Google, TikTok, LinkedIn, paid newsletters. We have run all five at scale and pick on incrementality, not on what looks tidy in a case study.
Conversion and email
Get more of your visitors to buy or enquire, and bring customers back with email and SMS that runs on autopilot.
The detail
We work directly with your engineers to ship A/B tests on pricing pages, sign-up flows, activation moments, paywalls.
Trigger-based flows, segmentation, value-based optimisation, retention loops. Customer.io, Braze, Klaviyo, Loops. We're tool-agnostic.
We model LTV per segment, CAC payback per channel, contribution margin per cohort. The numbers a board actually defends in a meeting.
We sit with PMs and engineers as collaborators. We do not lob tickets over the wall.
Part-time growth lead
An experienced growth marketer working inside your business a few days a week, for a fraction of the cost of a full-time hire.
The detail
You work with one senior operator week to week. They show up to your standups.
Paid, CRM, analytics, creative. One engagement covers the surface area, not the silos.
An operator who reports into your CEO or VP of Growth, embedded in your sprint cadence.
Your engagement is with Nf3. We employ the specialists and carry the delivery risk. One contract, one invoice.
Part 2
For businesses that want senior people running their ads, email and creative, without building a team to do it.

Price on call

We'll talk it through on a free 30-minute call and recommend one, or tell you if neither is right for you.
Who we work with
Founders and marketing leads at small and growing businesses (e-commerce, hospitality, services, SaaS and marketplaces) who want senior people running their paid media.
If your next 12 months of growth are the ones that need to land, we should talk.
How we compare
At a generalist agency, the senior person you meet in the pitch often hands the work to a junior team. At Nf3, senior people do the work, and we report results in sales, not impressions.
Running your own ads takes time away from running the business, and every lesson is paid for out of your own budget. With Nf3 you get your time back, and a decade of expertise behind every pound you spend.
A freelancer is often brilliant in one channel and quiet in the others. Nf3 covers paid ads, website conversion and email under one contract, rather than one channel.
Hiring a senior marketer full-time is a six-figure annual cost and takes months to recruit. Nf3 can have a senior specialist working in your business within two weeks, and you can scale up or down month to month.
Our process
Most agencies start at the creative. We start with the people who buy, then keep going round. Each pass through the loop makes the next batch of ads cheaper to produce and more likely to work.
We speak to your buyers, customers who have left, and people who nearly bought. We ask what customers actually did, not what they think they might do. Opinions are cheap, past behaviour is evidence.
We sort what we hear into the real reasons people buy from you, in their own words. We rank those reasons by how often they come up and how costly the problem is to live with, which tells us what to say before we decide how to say it.
Each reason becomes an angle, and each angle becomes a batch of ads. Volume is the point. Nobody can reliably pick which framing of a real problem will land, so we stop guessing and start shipping enough variants to find out.
Everything goes into a structured test with enough budget behind it to give a readable result. Losers get cut without ceremony. Winners get more budget and get rebuilt into fresh variants that pull on the same thread.
What won, and why it won, feeds back into the next round of interviews and the list of reasons people buy. The next cycle starts from evidence rather than a blank page, which is why month six looks nothing like month one.
Back to 01
The loop runs continuously for as long as we are engaged. Every round of interviews is sharper than the last, because we already know which reasons convert and which ones only sounded good in a workshop.
FAQ
You'll see early learnings within the first few weeks. Most accounts need 60–90 days of testing to find what reliably works, and we report progress every week.
Yes. If you're spending on ads, or ready to start, and want senior people running them, we'd love to talk.
You do. Ad accounts, dashboards, creative files and audience data are all in your name from day one.
A retainer is Nf3 running a channel or set of channels for you, from strategy through to reporting. A fractional engagement is a named specialist from our team embedding inside your business for an agreed number of days per week. Retainers suit businesses that want senior operators owning the work. Fractional suits businesses that already have a growth lead and need firepower in a specific lane.
Usually within two weeks. Discovery call, one-page SOW, kick-off the following Monday. We have onboarded clients in seven days when the brief was tight.
Per engagement. For paid, that's typically contribution margin, payback period, and incremental revenue. For product and CRM, it's conversion rate lift on the experiments that ship and downstream retention. We agree the success metric on day one and put it in the Friday report from week one.
A standard B2B services agreement between your company and Nf3, with a one-page SOW per engagement. We're happy to send a template before the discovery call if it helps.
Engagements are priced based on scope and the number of days per week. A full retainer running paid, CRM and creative across a single business sits at the higher end. A fractional specialist in one lane sits at the lower end. We share a price band on the discovery call once we understand the scope.
Yes. Nf3's client base splits roughly across the three. B2B SaaS clients have included Fyxer and JAAQ. Marketplace clients have included DELLI and Stasher. Consumer brand clients have included MOB, Lifted, Mother Root and No Logo. The founders previously led growth at Deliveroo (marketplace), OYO (marketplace), Fat Llama (marketplace) and across SaaS portfolios at TikTok and Google.
London, UK. We work with clients across the UK, Europe and the United States. Most work runs remotely with weekly in-person time when a client is London-based.
Nf3 was founded by Alex Sowter and Ellie Ivanova. Alex was previously Head of Growth at DELLI, UK Growth Operations Lead at Deliveroo, Growth Manager at Fat Llama (Y Combinator) and the first UK marketing hire at OYO. Ellie was previously at TikTok, where she built TikTok strategy for Nestle, Mars, Huel and Suntory, and at Google, where she audited more than 100 internal media campaigns across EMEA.
An agency retainer is Nf3 running a channel as your growth team, from strategy through to weekly reporting. A fractional engagement is one named Nf3 operator embedded inside your business for an agreed number of days a week, working in your tools and showing up to your standups. Both are contracted with NF3 GROUP LTD.
No. Every engagement, including a part-time specialist, is contracted with NF3 GROUP LTD. We employ the specialists, which removes the off-payroll (IR35) question that comes with hiring a sole-trader freelancer directly.
