Client reviews, on the record

Named founders and marketing leaders, in their own words.

Alex and Ali have a deep understanding of full-funnel pipeline generation. Ads, email, creative, landing pages, demand gen, lead gen, Clay. They've got you covered. They're a small, scrappy team that cares about results. Go with Understory to run your allbound and you will not be sorry.

Adam Robinson

CEO @ Retention.com & RB2B

For most of my eight years at Expensify we relied on product-led growth, without much of an outbound strategy. Working with Understory feels like taking on an internal employee with zero ramp-up, and we've seen material revenue from leads that are 100% attributable to our outbound with them. If you need a tooling-rich, full-scope go-to-market strategy quickly, they're a good fit.

Mitch Ward

Head of Go-to-Market @ Expensify

Understory has been an incredible partner to us. They are not only exceptionally skilled operators who understand B2B SaaS growth, but also a group of genuinely smart, proactive, and enjoyable people to work with. They really feel like an extension to the team, consistently bringing new ideas and executing at a high level. I definitely recommend them to any company looking for a true growth partner.

Nick Velkovski

Co-founder & CEO @ HeyReach

Understory took us from zero to probably one of the most compelling outbound motions I've seen. We've had about 365 positive replies and close to 75 meetings, our closed business has more than covered everything we've invested, and there's potentially eight figures in pipeline. I can't think of a better cold email partner.

Josiah Bryant

CMO @ FullPAC

We spent $50K with no ROI on LinkedIn ads, and then Understory spent a fraction of that and booked us 30+ demos in the first month and a half.

Ankit Kanoria

Chief Growth Officer @ Hiver

We'd never cracked paid social with previous agencies. Understory cracked LinkedIn, then Meta, and took our outbound to the next level. Paid media and outbound now account for 20 to 25% of our total pipeline and about the same share of revenue, up from 10 to 12%. They've been a force multiplier and an extension of our internal team.

Zach Sherrod

Head of Growth & Partnerships @ Northbeam

The Understory team excels everywhere. I knew Alex for a while as an early Clay expert, and eventually met Ali too before they became an enterprise partner. We discussed strategy and tactics, and I could just tell it was the right fit for our paid media efforts. This team excels across all channels, and there was no other agency that knew our audience better or could execute at their level.

Bruno Estrella

Head of Marketing @ Clay

When I joined Doppel to build paid media from the ground up, I went back to a partner I liked working with and picked Understory. We started with a very low five-figure budget on paid search and LinkedIn, and now we're getting toward mid-six figures and expanding from two channels to five. If you're looking for scale, they're the right team to partner with.

Rodolfo Yiu

Senior Director of Marketing @ Doppel

Understory jumped straight into an audit on our first call, and I cut them off about five minutes in because it was way better than what we had. They crushed any agency we'd had before. On paid social we 5x'd our leads on the same budget, and on search we doubled our lead goal, all without blowing up ad spend.

Logan LeBouef

Former Head of Marketing @ Knit

Jumping into projects with Understory has been a game-changer for our ad campaigns across LinkedIn and Google. It's like they scour the couch cushions for every last penny to make sure our budget stretches as far as it can go. With a keen eye for detail and a knack for making every dollar count, Understory's approach is a breath of fresh air.

Joseph Barringham

Director of Demand Gen @ Sonrai Security

I interviewed a lot of GTM engineering firms, and plenty of them aren't tied to outcomes. Understory had a really deep conversation with us about strategy and performance, and looked at outbound as a go-to-market channel. We did 26 opportunities in Q1 and 18 so far in Q2, closed seven, and we're ROI positive on the channel.

Connor Jeffers

Founder & CEO @ hapily

Paid media has become one of our top channels for creating qualified leads, and we recently won a deal from our LinkedIn ads in one of our strongest markets. Understory asked for our closed-won accounts by region and built lookalike audiences from them. And they don't charge a percentage of spend, which I think can be exploitative as you start growing.

Agnayee Datta

Director of Marketing @ Vicarius

Working with Understory has been refreshing. They jumped right into a highly technical niche and got up to speed on the nuances of our industry. They didn't try to reinvent the wheel, but instead used their expertise to build on our early strategies and successes.

Jono Krawczyk

Growth Marketing @ SecureW2

I talk with Understory for about 90 minutes a month, and they turn it into 10 to 20 LinkedIn posts aligned to my voice. Most get 5,000 to 10,000 impressions, one hit 50,000, and engagement is up 600% on the prior 90 days. For the time and money involved, it's a great way to get more visibility.

Chris Fezza

CEO & Co-founder @ Operatus

Our customers are hard to find on Apollo, and our last agency came back with laughably small lists. Understory went to sources like Google Maps and found more leads than I thought was possible. We've had about 300 positive replies in two active months, more than we can handle, and it looks like cold email will stand up as one of our primary channels.

Eric Golman

CMO @ WareSpace

We really couldn't ever imagine working without the Understory team, so I heavily recommend them for anyone really trying to look and build their business and really meaningfully grow.

Jordan Shamir

CEO @ Yofi

My co-founder and I had zero paid media experience. Understory came up over and over again in conversations with our founder friends, especially in Y Combinator, and this year we've 5x'd our revenue since we started working with them. Recommending Understory to other founders is a no-brainer.

Sriharsha Guduguntla

CEO & Co-founder @ Hyperbound

At the start of the new year, we observed a 40% increase in our campaign performance, a testament to their hard work and expertise. We are genuinely impressed and excited by the results achieved, and look forward to our continued partnership.

Angelica Krauss

Director of Marketing @ Remofirst

Understory team did a thorough audit on our paid media campaigns, found multiple weak spots, and proactively suggested tactics for us to implement. We were so impressed with the audit that we hired them for both paid social and paid search that week.

Gleb Polyakov

CEO @ Nylas

We wanted to scale outbound without adding headcount, and Understory was the only real option we considered. In some months we were bringing our SDR team 80 to 90 positive conversations, and we made the model work even with a really small ICP and TAM.

Matthew Hoyle

VP of Growth Marketing @ PatientNow

Working with Understory has been effortless. The syncs were regular, setup was fast and I was pleasantly shocked at the sheer pace Understory work at. This coupled with the passion and excitement Alex and Ali show has made them a pleasure to work with.

Scott Ferguson

Director of Revenue Marketing @ Netacea

They've completely transformed how we approach outbound campaigns. Before we were really struggling with weak positioning and limited reach, but after we partnered with Alex and Ali, we experienced steady, and really consistent growth.

Luis Perdomo

Director of Marketing @ Verify Treatment

It was clear they actually cared about delivering results for us, not just putting us through some generic, templated system. They really spend the time to understand what will create value for us, built a strategy, and then kept iterating on it to get better and better results.

Ryley Randall

CEO @ Devize

These guys are real nerds at this stuff. They make our campaigns work and I don't have to do any heavy lifting at all. After a successful exit, I'm focused on A players only, and Understory is exactly that. Trust the nerds. You won't regret it.

Eric Spett

CEO @ Scalebound

Working with Understory allowed us to reach tens of thousands of prospects and return multiple daily positive leads. They helped us locate potential users of our tool and dial in our messaging so that when we reached out, people responded positively.

Arel Moodie

Co-Founder @ Talkadot

I worked at Google for over 10 years with many performance marketing agencies and Understory is one of the best.

Jonathan Pelosi

CRO @ Avo

Working with Understory for my email campaigns has been what I wish every agency experience was like. They're shrewd, on the bleeding edge of the newest tech, organized, and timely. My favorite part about working with them has probably been their proactivity, and ability to adapt quickly.

Itai Joseph

CEO @ Fondu

Understory is incredible to work with. They're so creative in the way they approach ad creatives and copy, but extremely tactical and calculated with the way they manage ad spend. A year in, and I can't think of a better partner to work with.

Alia Vinson

Senior Marketing Manager @ VERO

Before Understory, we struggled to find a LinkedIn Ads agency that didn't just run us through generic playbooks. Since partnering with Understory, LinkedIn Ads has become one of our top acquisition channels, delivering some of our largest sales opportunities every week.

Mike Kilcullen

VP of Marketing @ Wiza
