verdict
Rock The Rankings is the Single Grain alternative for B2B SaaS teams between $2M and $50M ARR that want a SaaS-only specialist rather than a horizontal agency, AI search and Google as the whole practice rather than one service among six, Founder, Justin Berg, on the account rather than a team under a well-known CEO, and tiers published from $5,050 a month against a $10,000 minimum, with a demo forecast written before the agreement. Skale ranks highest among the other alternatives for high-growth SaaS that want an SEO revenue team reporting in MRR. Aimers is the pick for a SaaS-only paid team if paid is the lever. Single Grain remains the right choice for a company that wants SEO, paid, content, CRO, and AI implementation managed by one recognized agency across SaaS, ecommerce, and enterprise.

Wighted criteria, pipeline impact first. Filter by how each agency is built.
Editorial scores by the Rock The Rankings team · Review counts from Clutch.co · Updated quarterly
How we scored
We reviewed public case studies, client rosters, pricing pages, and third-party reviews. One question outranks the rest: does the agency connect search activity to pipeline you can audit, or does it report traffic and hope you are impressed.
The breakdown
Read the criteria, check the results, and judge for yourself. Every other entry gets the same fields and an honest tradeoff line.
Discovered Labs is a London agency founded in 2024 by Liam Dunne and Ben Moore that treats answer engine optimization as the whole practice: daily content engineered for AI citation, an in-house visibility tracker, and month-to-month, performance-based terms from €5,495, with clients working directly with the co-founders. Four Clutch reviewers rate it 4.9.
It answers the AI-practice, founder-access, and price preferences at once. The trade is the short record.
SimpleTiger, in Sarasota since 2006 and SaaS-only throughout, runs SEO with AI search optimization, citation outreach, paid search, and Webflow development on month-to-month terms from $4,000. Thirty-four Clutch reviewers rate it 4.9.
It answers the SaaS-only and price preferences while keeping paid available. It does not change the reporting unit.
Skale, founded in London in 2020, sells itself as an SEO revenue team for high-growth SaaS and fintech, runs GEO and SEO as a single system, and reports in signups and new MRR. Twenty-three Clutch reviewers rate it 4.9.
It answers the SaaS-only and AI-practice preferences and changes the reporting unit. It does not publish pricing or run paid.
Founded in Austin in 2019, Omniscient Digital built its AEO practice on its own study of 23,000 AI citations and publishes cases with AI visibility and pipeline figures. Engagements run annually from $10,000 a month, reported in pipeline and ARR, and 18 Clutch reviewers rate it 4.9.
It answers the SaaS-only and AI-practice preferences and deepens the research. It does not lower the entry or shorten the term.
Aimers, founded in 2015 as Teamedia, runs performance marketing for B2B SaaS and tech from Tbilisi and Hong Kong with 50 to 249 people: paid search and paid social on Google, Meta, Bing, and LinkedIn, conversion optimization beside it, and spend reported against qualified pipeline. Its Clutch record is 4.9 across 25 reviews.
It answers the SaaS-only preference inside Single Grain's paid discipline. It does not run organic.
Garrett Mehrguth founded Directive in 2013; it now runs three divisions across six offices with more than 130 people, works only with B2B technology companies, and has served nearly 300 SaaS companies. The Performance division delivers paid media, SEO, creative, programmatic, and RevOps under the Customer Generation method; 56 Clutch reviewers rate it 4.8.
It answers the B2B-only preference at Single Grain's breadth. It does not change the structure or publish pricing.
Dev Basu's Powered by Search has sold B2B SaaS demand generation from Toronto since 2009 as three published-tier levers, paid media, SEO and LLM visibility, and RevOps, each run by a senior-only pod and backed by a 30% pipeline guarantee in 90 days, with SentinelOne, Varonis, and Basecamp among named clients.
It answers the SaaS-only and published-price preferences and keeps several channels. It has no Clutch record.
How to choose
FAQs
If yours is not here, bring it to the call. Same unpolished answer either way.
Single Grain is a Los Angeles digital marketing agency founded in 2009 and led by CEO Eric Siu that runs SEO and Search Everywhere Optimization, paid media, content, CRO, performance creative, and AI implementation for SaaS, technology, ecommerce, and enterprise brands. It prepares a custom proposal after a consultation; Clutch lists a $10,000 minimum with most engagements between $10,000 and $49,999, and third parties estimate $5,000 to $50,000 a month depending on scope.
The reasons B2B SaaS buyers give are wanting a SaaS-only agency, wanting organic and AI search as the practice rather than one of six services, wanting the founder or a senior operator on the account rather than a team under a recognized name, and wanting a published price below $10,000. None of them is a complaint about the work; its 12 Clutch reviews raise no significant areas for improvement.
Directive and Powered by Search run the closest multi-channel programs, narrowed to B2B technology or B2B SaaS. SimpleTiger is the closest SaaS-only agency that still runs paid. Rock The Rankings, Skale, Omniscient, and Discovered Labs are the opposite shape: one practice built deep.
On this page, SimpleTiger starts at $4,000 a month, Rock The Rankings at $5,050, Discovered Labs at €5,495, Powered by Search at $6,000 for paid and $9,000 for organic, Omniscient Digital at $10,000 on annual terms, and Aimers, Skale, and Directive quote from minimums between $4,000 and $5,000.
A horizontal agency brings patterns from other categories and can run several channels from one contract. A SaaS specialist knows the comparison surface, the trial-and-demo funnel, and the buying committee without a ramp. Most SaaS teams on this page's criteria already have paid in house and buy organic from a specialist, which is why six of the eight alternatives serve SaaS only.
We did. Rock The Rankings publishes this list and ranks itself, and every agency on the board is scored on the same seven weighted criteria shown above; Single Grain itself is profiled and not scored. Our routing list points to a competitor where one fits better.
