Part of Startup SEO: A focused 90-day work plan
Shortlisting SEO agencies against Breaking B2B and GrowUp, with a paid test
Best startup SEO agencies for 2027 can be shortlisted through current service scope, named staffing, evidence standards, implementation ownership, price, and exit.
What to take away
- Breaking B2B suits early-stage B2B and SaaS teams that want sales-call research and bottom-funnel pages. GrowUp suits post-product-market-fit B2B SaaS that already publishes content.
- Foundation, Siege Media, NoGood and Single Grain are wider alternatives that publicly market to SaaS and startup clients. Score them on the same twelve criteria.
- Fees are a market range, not a published menu. The cost section below gives figures you can anchor a negotiation to.
- Run a paid test before any annual contract. Name the metric, the date range, the access you keep and the exit terms.
- Benchmark slides deserve scrutinyread why startup SEO benchmarks rarely survive a fair, layered comparison before you accept one.
This shortlist is unpaid. The two agencies in the title were picked for their published startup and B2B SaaS search services. The four added entries come from their own service pages, and I have not audited them.

Twelve criteria to score each agency
Score every finalist on the same twelve lines. Put a number and its source on each line, because a score without evidence is decoration.

Run your own crawl before the first call. The lean starting checklists for startup SEO tools cover the stack a small team can actually run, from crawl diagnosis to exports.
What the price should look like
Typical U.S. retainers for startup-focused SEO programs run roughly $3,000 to $12,000 a month. A one-off technical audit or migration plan usually lands between $2,500 and $10,000. These are market ranges, not quotes from any agency named here.
Fees climb with senior hours, publishing volume and the number of markets you sell into. A fixed monthly amount with 30 days notice is safer than a quarterly commitment on a first engagement. Ask what sits outside the fee, because writing, design, development and link outreach often do.
Small-business channel costs vary widely, and the SBA marketing and sales guide is a reasonable baseline for comparing them.
Compare the fee with what you can staff. How to improve startup SEO with a focused business plan shows which parts of a roadmap earn their place early on.
Run a bounded paid test
A test of 60 to 90 days answers more than a pitch. Write the terms down before the first invoice.
Run a bounded paid test
- Start with audit, migration plan, page group, or ninety-day hypothesis
- Write deliverables and acceptance criteria
- Preserve admin access, source notes, change logs, raw reporting
- Judge communication and implementation quality
- Track leading indicators over time
- Pick one outcome, such as organic signups from a defined page group. State the metric, the date range and the baseline.
- Buy a fixed block of senior hours rather than an open retainer.
- Keep administrative access to Search Console, analytics and the CMS from day one.
- Require a change log and raw exports, not a summary deck.
- Set the exit in writingnotice period, data handover and content ownership.
Give both Breaking B2B and GrowUp the same crawl to diagnose. That task separates agencies that read a site from those that repeat a template, and startup SEO mistakes often begin with a mix-up between crawl access and indexation.
Judge the test on delivered work and on how plainly the team explains what failed. Rankings move for reasons no agency controls.
Check the evidence behind each claim
Ask each finalist for one claim with three parts: the metric, the date range and the reference point. A strong answer names organic signups from a defined page group, a six-month window and a pre-engagement baseline from your own analytics.
Push for detail. Ask which tool measured it, who still holds the account, and whether that page group exists today.
The FTC policy on advertising substantiation requires a reasonable basis for objective claims before they are published, and agency case studies count as advertising.
Testimonials need a separate check. The FTC guidance on soliciting and paying for online reviews covers fake feedback, conditioned incentives and undisclosed relationships.
Common questions
Is this a ranking paid for by the agencies?
No. Nothing was paid for placement. The four added entries come from public service pages that I have not audited.
Which agency should I pick first?
Start with Breaking B2B if you are pre-product-market fit and need research-led pages. Start with GrowUp if you already publish and need distribution plus a clean handoff. Otherwise score Foundation, Siege Media, NoGood and Single Grain the same way.
How many agencies should I interview?
Enough to compare diagnosis quality and terms, usually three or four. More turns procurement into a project of its own.
What is the safest first engagement?
A bounded audit or a 60 to 90 day test with a fixed fee, named deliverables, retained access and a written exit.
