Jer — ads by jer

I'm not a consultant. I'm an operator who writes reports.

I spent eleven years running paid in-house. Started on the growth team at an on-demand company in 2014, then did stints across consumer marketplaces and, for the last five years, B2B SaaS. Budgets from $40K/mo to $14M/quarter. Every major channel at least once.

In 2022 I left to co-found a food & bev company. It didn't work. I went back to what I'm actually good at — reading accounts and writing what I see. This is that, productized. One price, two weeks, one document.

01Worked at
Four venture-backed co's between Series B and public. Growth teams of 2 to 18.
02Stages
Seed bridge → IPO. Usually most useful between $5M and $80M ARR.
03Channels
Google, Meta, LinkedIn, TikTok, YouTube, Reddit, Apple, Amazon, DV360, affiliate.
04Biggest line item
$14M / quarter in paid social at a marketplace that rhymes with "delivery."
05Opinions
Creative > bidding. Your MMM is probably wrong. Brand search isn't free.
06Not for
Consumer DTC, gaming, series-seed pre-revenue. I'll tell you and refer.

Section 1 of 5
TL;DR

You're spending $2.1M / quarter. ~34% of it is not producing pipeline.

The short version: Google Brand is doing Google Brand. Your LinkedIn Sponsored spend has 3 audiences that overlap 71% and one ABM list that hasn't been refreshed since 2024. Meta is a creative problem, not a budget problem.

If you execute the top 6 recommendations, my model says you recover ~$680K/quarter in wasted spend and open up two new viable channels. Full math in Section 2.

Skeptical ICP, mostly LinkedIn + branded Google. Spending like a Series D.

Found $190K/qtr we were flushing into LinkedIn lookalikes that overlapped 70% with our ABM list. Two weeks to fix. Paid for itself in three.

§ 07 — Word of Mouth

What operators say when Jer isn't in the room.

01 / 02

“Jer is an excellent thought partner for ads. He's always willing to go the extra mile or offer suggestions on how to squeeze more from our current ad sets or better align our landing pages. We work with Jer because he takes the time to learn the business and understand what our customers are looking for.”

Nick Allain
VP Growth Marketing · Proservice Hawaii

“Jer is a rare combination of deep performance marketing expertise and true business ownership, and is an asset to any executive team that cares about efficient, scalable growth. He has high agency, and works around the clock to make things happen. At Pilot, he took full ownership of paid search and turned it into one of our most reliable and efficient pipeline engines, consistently meeting all KPIs; in several months he drove 30–40% of total company pipeline and ARR through branded and non-branded campaigns.

Since his time at Pilot, it has been great to see Jer continue to evolve his craft and expand his impact in the ecosystem. While I haven't managed him directly since then, it's clear from the companies he partners with and the reputation he has built that he's grown into a true paid media leader and agency owner. He brings the same rigor, ownership, and cross-functional mindset he demonstrated in-house, and it's no surprise to see him become a trusted partner for teams looking for both strategic guidance and hands-on execution.”

Rao Adavikolanu
CMO · Pilot

“Jer was a huge help in cleaning up and optimizing Google Ad campaigns at a fintech startup where I was the Director of Marketing. He brought a unique blend of expertise in strategy, analytics, and creative, allowing him to operate as a true one-man team. Highly recommend working with Jer. Great guy and a hard worker.”

Nate Eldridge
Director of Marketing · Harness Wealth

“Before Jer came on board, our growth relied mostly on word of mouth and connections. As a growing company, we knew we needed something more intentional. Jer didn't just bring us a process—he brought energy, intelligence, and thoughtfulness that is reshaping how we reach potential clients.

What stands out most is Jer's mix of positivity and precision. He looks at how each outreach step ties back to results. You can feel that he's not just 'running a system,' he's designing ways for us to connect with the right people at the right time. Working with Jer has opened doors for us as well as opened our minds to a new way of building business.”

§ 10 — FAQ

Questions, answered.

If yours isn't here, email me. Real humans only — jer@adsbyjer.com.

A couple reasons. It's what a growth VP can expense without approval. It's about three days at my in-house IC rate — 25 hours of scope, priced honestly. And it's cheap enough that if you don't love it, I refund and we both move on.
Fine. I'll go deeper on that channel. Price doesn't scale with scope — one number, no quote calls, no SOW ping-pong.
Yes. The audit stands alone — plenty of teams wrap at day 10 and run the roadmap themselves. If you want me to actually execute it, I take fractional retainers: I work it day and night, more like an operator on your team than a consultant on a SOW. The full $5,000 audit fee credits against the first month.
Your agency needs you to keep spending. I don't. Most of what I find is your agency's fault. Not a dig — they're doing the job you hired them for. This is a different job.
Share-access (not admin) to every ad platform, GA/analytics, your warehouse if you have one, 18 months of spend CSV, and a 30-min kickoff with whoever owns growth.
Mutual NDA before kickoff. I'll send mine or sign yours — I've read both kinds of template, either works.
About a third of my audits come from agencies wanting an outside opinion for a client. I can sign with the agency or the client, up to you.
Hasn't happened. But if I find less than $15K/qtr of recoverable spend, I refund 50%. I've written that sentence 137 times and paid it out zero.
B2B SaaS — devtools, data, security, fintech infra, HR tech, AI-native. I've done consumer marketplaces before but that was a different life.
San Francisco. I work in PT, comfortable with ET, and flexible across most other time zones. I don't travel for the audit — it's all async and Zoom.
