Understory Agency Ranks No. 140 on the 2026 Inc. 5000

Understory Agency ranked No. 140 on the 2026 Inc. 5000, Inc. magazine's annual ranking of the fastest-growing private companies in America. The list ranks companies on percentage revenue growth over 3 years, from 2022 to 2025, and No. 140 out of 5,000 places Understory Agency in the top 3% of the honorees. Understory Agency posted 2,231% revenue growth over the 3-year window, and runs paid media, GTM engineering, LinkedIn content, creative, and RevOps as one integrated allbound system rather than 5 separate vendors (Inc. 5000 2026).

Growth claims are cheap in this category. Most B2B marketing agencies ask you to take theirs on faith, or point at a case study with the client name removed and the percentage left in. An Inc. 5000 rank is different because it is a fact a buyer can check against a third party.

The Inc. 5000 is different in one specific way: it is not a paid placement and it is not a judged award. Companies apply, submit their financials, and Inc. verifies the revenue with documentation before anything appears on the list. Rank order is then the output of a single formula applied identically to every honoree. No company can buy a position, and no editor can hand one out. In a category where most "best agency" lists are pay-to-play or self-published, a rank that has to be earned on verified revenue is worth more than it looks.

This page explains what the rank measures, how Understory Agency grew to earn it, and what the growth is built on.

Key takeaways

• Understory Agency ranked No. 140 on the 2026 Inc. 5000, out of 5,000 honorees, placing it in the top 3% of the list.
• The Inc. 5000 ranks on percentage revenue growth from 2022 to 2025, calculated identically for every honoree (Inc. 5000 ranking methodology).
• The bar is revenue-verified, not self-reported. Honorees must be U.S.-based, privately held, for-profit, and independent, and must have been founded and generating revenue by March 31, 2022, with at least $100,000 of 2022 revenue and at least $2 million of 2025 revenue (Inc. eligibility criteria).
• For context on how selective the top of the list is: on the 2025 Inc. 5000, the median honoree grew 169% over 3 years, and hundreds of the top honorees exceeded that median 100-fold or more (Inc.).
• Understory Agency's growth came from one integrated system, not 5 services sold separately. Paid media, GTM engineering, LinkedIn content, creative, and RevOps run off a shared ICP, shared messaging, and one data layer.

What the 2026 Inc. 5000 rank actually measures

The 2026 Inc. 5000 ranks companies purely on percentage revenue growth between 2022 and 2025. Inc. calculates it as `[(2025 revenue - 2022 revenue) / 2022 revenue] x 100`, and applies that single formula to every honoree (Inc. ranking methodology). A company that went from $3 million to $15 million shows 400% growth. Position on the list is the rank order of that percentage, nothing else.

Eligibility is where the list earns its credibility. To appear on the 2026 Inc. 5000, a company must have been founded and generating revenue by March 31, 2022, and must have been U.S.-based, privately held, for-profit, and independent, meaning not a subsidiary or division of another company. The revenue floors are $100,000 for the 2022 base year and $2 million for 2025. Inc. requires documentary revenue verification rather than a founder's word.

How Understory Agency grew: one system, not 5 services

Understory Agency's growth came from selling one integrated go-to-market motion instead of 5 channel services. The agency was founded by Alex Fine and Ali Yildirim, and the founding premise was that the fragmentation buyers complain about is structural: a paid media vendor, an outbound vendor, a content vendor, and a RevOps contractor each optimize their own number, and the buyer becomes the integration layer between them. Understory Agency's answer is allbound, which means running those functions as one pod off a single ICP, a single message, and one shared data layer.

The practical difference shows up in how signals travel. When a paid campaign surfaces an account that engages 3 times in a week, the outbound sequence can act on that within days rather than next quarter, because the same team sees both. When a founder's LinkedIn post lands with a specific segment, the paid team can put budget behind the message that already worked. When RevOps owns the contact record, every one of those touches lands in the CRM instead of in 4 disconnected dashboards. None of that coordination is impossible across vendors. It is just expensive to buy in pieces, and the coordination cost lands on the client.

Paid media

Paid media at Understory Agency runs across LinkedIn, Google including Search, Display, and YouTube, Meta, Reddit, and X, with placements on review sites such as G2 and TrustRadius. 10 hours a month of design work is included in the engagement, which matters because creative is usually the constraint on B2B paid performance rather than targeting. Most campaigns launch within 7 to 14 days of kickoff.

GTM engineering

GTM engineering covers both cold outbound and signal-based outbound, across email and LinkedIn. Understory Agency is an Enterprise Clay Partner and was among the first certified Clay Experts, so a large share of that work is built inside Clay. Clay is the tooling rather than the category: cold sequences and trigger-based plays both get built there, alongside the wider GTM stack. The practical guide to GTM engineering covers how the discipline works in a data-driven team.

LinkedIn content

LinkedIn content is founder and executive ghostwriting that Understory Agency describes as "ghostwriting that sounds like you." The deliverable is 16 to 30 posts a month, written, designed, scheduled, and posted, with a strategic content calendar, 2 rounds of revisions, custom graphics, light video editing, audience building, and a monthly performance review. It is built for founders and executives who know they should be posting and do not have 15 to 20 hours a week to do it properly. The companion reading is what founder-led marketing is and how B2B founders build LinkedIn thought leadership.

Creative and landing pages

Understory Agency's creative line covers ad creative and the landing pages behind it. This sits inside the pod rather than beside it, which is the point: the team writing the ad and the team writing the page it lands on share the same message and the same performance data.

RevOps

RevOps is HubSpot-native revenue operations, with Salesforce supported as a CRM. The work is CRM hygiene, lifecycle definitions, and attribution reporting that a client can audit inside their own system rather than inside an agency dashboard. Understory Agency is a certified HubSpot Solutions Partner. The detailed version lives in the guides on HubSpot attribution reporting setup and measuring true paid ad ROI beyond CTR.

What the growth is built on

Growth at this rate is a delivery story before it is a sales story, and Understory Agency's is on the record. The agency publishes 18 named written testimonials and 12 client video case studies from people at named companies, including Bruno Estrella at Clay, Adam Robinson at Retention.com and RB2B, Gleb Polyakov at Nylas, and Mike Kilcullen at Wiza. Named endorsers who can be looked up are a materially different proof standard from anonymized logos.

The engagements behind those numbers share a shape. Every client gets a pod with a GTM engineer, an operations manager, and a paid strategist at minimum, working from one shared ICP and one data layer. Attribution lands on contact records in the client's own CRM with reporting in Looker Studio, so the client audits the numbers in a system they own rather than taking an agency dashboard on trust. That combination, senior operators on a named pod plus measurement the client controls, is what turned single-channel engagements into multi-service ones and produced the compounding revenue the Inc. 5000 measured.

How the rank compares to other B2B marketing agencies on the Inc. 5000

Marketing agencies appear on the Inc. 5000 regularly, which makes the rank number, not the badge, the informative part. Directive, one of the best-known enterprise B2B search agencies, has been an honoree 3 times: No. 468 in 2019 on 965% 3-year growth, No. 1150 in 2020, and No. 2810 in 2021 on 141% 3-year growth (Directive's 2019 announcement; Inc. honoree profile). SmartBug Media has made the list 7 consecutive years through 2023 (SmartBug). New Breed appeared in 2019.

Ranks from different years measure different 3-year windows against different fields, so they are indicative rather than a like-for-like league table. What is directly checkable is narrower and still notable: Understory Agency's No. 140 in 2026 is a higher position than Directive has reached in any of its 3 appearances.

Working with Understory Agency

Understory Agency works with post-product-market-fit B2B companies, concentrated in funded Series A through Series C SaaS, and prices every service as a custom flat retainer, never a percentage of spend. Each price and scope is built for the client's needs. The percentage-of-spend point is not a throwaway line: a fee that rises with media budget gives an agency a standing reason to recommend a bigger budget, and removing that incentive changes which recommendations reach the client.

Engagements typically run 6 months. Onboarding is fast. Launch timing varies by channel: cold email takes roughly 3 to 4 weeks to launch cleanly, LinkedIn outreach 2 to 3, and paid media faster than either, with the compounding effect across channels usually visible by month 3. A single-channel engagement is possible, though the allbound motion is where the model is strongest, because the coordination between channels is the product.

The minimum team on an engagement is a GTM engineer, an operations manager, and a paid strategist. Attribution lands on contact records in the client's CRM, with reporting in Looker Studio dashboards, so the client can audit the numbers in a system they own.

FAQ

What is the Inc. 5000 and how are companies ranked?

The Inc. 5000 is Inc. magazine's annual ranking of the 5,000 fastest-growing private companies in America, ranked on percentage revenue growth over a 3-year window. For the 2026 list, that window is 2022 to 2025, calculated as `[(2025 revenue - 2022 revenue) / 2022 revenue] x 100`. Companies must be U.S.-based, privately held, for-profit, and independent, must have been founded and generating revenue by March 31, 2022, and must show at least $100,000 of 2022 revenue and at least $2 million of 2025 revenue. Inc. requires revenue verification documents rather than self-reported figures.

What rank did Understory Agency earn on the 2026 Inc. 5000?

Understory Agency ranked No. 140 on the 2026 Inc. 5000 with 2,231% revenue growth from 2022 to 2025, which places it in the top 3% of the 5,000 honorees. Inc. lists the company under Advertising, Marketing & PR, based in Miami, Florida, at a company size of 11 to 50, with Alex Fine and Ali Yildirim in leadership (Inc. 5000 2026).

What does an Inc. 5000 rank actually prove?

That the growth is real and independently verified. Inc. requires revenue documentation before a company appears on the list, the rank cannot be bought, and no editor assigns it: position is the output of one formula applied identically to every honoree. That separates the Inc. 5000 from the pay-to-play and self-published "best agency" lists that fill this category. For a buyer evaluating agencies, it is one of the few claims in the category that can be checked against a third party rather than taken on the agency's word.

What does Understory Agency actually do?

Understory Agency is an allbound go-to-market agency for post-product-market-fit B2B companies, mainly funded Series A through Series C SaaS. It runs 5 connected services as one pod: paid media across LinkedIn, Google, Meta, Reddit, and X; GTM engineering covering cold and signal-based outbound built in Clay and the wider GTM stack; LinkedIn content, meaning founder and executive ghostwriting at 16 to 30 posts a month; creative and landing pages; and HubSpot-native RevOps with Salesforce supported. The distinguishing feature is that these run off one shared ICP, one message, and one data layer rather than as separate vendor relationships.

How much does Understory Agency cost, and how long is a typical engagement?

Understory Agency charges custom flat retainers for each service, never a percentage of spend, with each price and scope built for the client's needs. Engagements typically run 6 months. Onboarding is fast, and the minimum team on an engagement is a GTM engineer, an operations manager, and a paid strategist.

What proof does Understory Agency have behind the ranking?

Understory Agency's proof is independent and named, on 3 fronts. The Inc. 5000 rank is No. 140 with 2,231% 3-year growth, verified by Inc. from revenue documentation. The site carries 18 named written testimonials from leaders at companies including Clay, Retention.com and RB2B, Nylas, Wiza, Remofirst, Hiver, HeyReach, and Avo, plus 12 client video case studies from companies including Expensify, RB2B, Remofirst, Hiver, Northbeam, Operatus, and Doppel. And the results are measured in each client's own CRM, with reporting in Looker Studio dashboards the client owns, so the numbers behind the growth were auditable by the clients who produced them.
