7 Best SEO Companies for Startups

Startups buy SEO under conditions that make most agency models a bad fit. The runway is finite, the positioning may change twice before the engagement ends, and nobody has eighteen months to wait for a content programme to compound. A twelve month contract signed in month one is a bet on a strategy that might not survive the next board meeting.

What an early stage company actually needs is an agency comfortable with ambiguity: one that will build around a narrow wedge of high intent queries first, prove the channel works, and scale from there. The seven below were verified on their own websites and each one names startups, scaleups or early stage companies as a client type.

What early stage companies should buy first

Sequencing matters more at this stage than it does anywhere else, because you are spending money you may not be able to spend again.

• A narrow keyword wedge with genuine commercial intent, rather than a hundred informational topics.
• Technical foundations that will not have to be redone after the next site rebuild.
• Content written by someone who understands the category vocabulary, not a generalist.
• Enough links to make the wedge rankable, since a new domain starts with no authority at all.
• Measurement tied to signups or pipeline, not to sessions. The Google SEO starter guide is a reasonable baseline if you want to sanity check what is being proposed.
• Month to month or short term terms, so you can stop if the thesis changes.

Seven SEO companies that work well with startups

1. Single Grain

Best for: Funded startups scaling several channels at once
Core services: SEO, answer engine optimisation, paid media, content, AI workflows
Pricing: Custom pricing
Website: singlegrain.com

Single Grain works across search, AI search surfaces, paid media and creative, and states that a senior strategist responds within twenty four hours. For a funded startup that needs organic and paid running in parallel rather than sequentially, that breadth saves vendor management time.

The agency has also leaned hard into deploying AI agents and workflows inside client marketing teams, which suits a small team trying to produce more than its headcount allows.

Pros

• Organic and paid under one roof for fast channel testing
• Strong footing in AI search as well as classic SEO
• Senior response built into the sales process

Cons

• Better suited to funded companies than bootstrapped ones
• No published pricing

2. NoGood

Best for: Venture backed companies wanting an embedded squad
Core services: SEO, answer engine optimisation, paid, content, creative, organic social
Pricing: Custom pricing
Website: nogood.io

NoGood builds dedicated growth squads rather than assigning an account manager, and names startups and scaleups alongside large brands as its client base. The squad model is close to hiring a team you do not have to recruit, which is the main constraint at this stage.

The offer spans paid, organic, creative and social, so a startup can test several acquisition routes without signing with four vendors.

Pros

• Embedded squad model rather than arms length account management
• Covers the full growth mix, useful when the winning channel is unknown
• Established track record with venture backed companies

Cons

• Premium positioning, likely out of reach pre seed
• No published pricing

3. Siege Media

Best for: Startups competing on content and digital PR
Core services: Generative engine optimisation, content marketing, digital PR, affiliate, consulting
Pricing: Custom pricing
Website: siegemedia.com

Siege Media built its reputation on content that earns links by itself, and has since repositioned around generative engine optimisation while keeping content and digital PR at the centre. It names SaaS, fintech, ecommerce and health as the verticals it works in.

For a startup whose category is won by being the reference article everyone cites, this is the model that produces that outcome. It is slower than paid acquisition and more durable.

Pros

• Content that is designed to earn links rather than just rank
• Digital PR capability in house
• Early and credible move into AI search visibility

Cons

• Content led, so it is not the answer to a technical problem
• No published pricing

4. Rank Shifters

Best for: Startups that need authority fast on a new domain
Core services: Link building, technical SEO, content, digital PR, SaaS and ecommerce specialisms
Pricing: Custom, quoted within one working day
Website: rankshifters.com

A new domain has no authority, which is the single biggest reason early stage SEO stalls. Rank Shifters is built around closing that gap: editorial placements on publishers with verified organic traffic, scoped against your keyword map rather than bought from a bulk list.

Terms suit the stage. There is no long term contract, pricing comes back within one working day without a mandatory discovery call, every publisher is approved by you before outreach, and placements carry a twelve month replacement guarantee. Writers with subject knowledge handle the content, which matters when your category has vocabulary a generalist will get wrong.

Pros

• No long term contract, which fits an uncertain runway
• Pricing without a mandatory sales call
• Authority building aimed at the specific pages you need to rank

Cons

• Not a full growth agency, so paid media needs a separate partner
• Scoped per campaign rather than sold as a fixed package

5. Embarque

Best for: Bootstrapped startups on a small budget
Core services: SEO, content, SEO for large language models, CRO
Pricing: Published pricing, monthly with no lock in
Website: embarque.io

Embarque is one of the few agencies on this page that publishes pricing openly and sells monthly with cancellation at any time and a money back guarantee. For a bootstrapped company, that removes most of the risk of trying the channel at all.

The work is content and SEO led for fast growing software and marketplace companies, with optimisation for large language model surfaces alongside classic search.

Pros

• Pricing published openly on the website
• Month to month with cancellation at any time
• Built for small teams rather than adapted from enterprise work

Cons

• Smaller scope than a full service agency
• Less suited to complex technical SEO problems

6. Ten Speed

Best for: B2B startups selling to companies
Core services: SEO, answer engine optimisation, content, digital PR, thought leadership
Pricing: Custom pricing
Website: tenspeed.io

Ten Speed is a United States based organic growth agency working exclusively with B2B companies, covering SEO, answer engine optimisation, content, social and digital PR as one programme rather than separate line items.

For a B2B startup, the useful part is that the agency treats pipeline rather than traffic as the outcome, which changes which keywords get prioritised early.

Pros

• B2B only, so no translation needed from consumer playbooks
• Organic channels run as one coordinated programme
• Explicit focus on pipeline rather than sessions

Cons

• Not relevant for consumer startups
• No published pricing

7. Sure Oak

Best for: Startups that want a senior strategist on the account
Core services: SEO, generative engine optimisation, link building, content
Pricing: Custom pricing
Website: sureoak.com

Sure Oak assigns a strategist with more than ten years of experience to every engagement and positions itself against the cheap, heavily automated end of the market. For a founder without an in house marketer, having one experienced person owning the strategy is worth more than a bigger team producing more output.

Link building sits at the centre of the offer, alongside content and answer engine work.

Pros

• Senior strategist on every account by design
• Clear position against automated low quality link building
• Authority and content handled together

Cons

• Not startup specific, so you are one client type among several
• No published pricing

What to Look For Before You Sign With Any Agency

Four things separate an agency that genuinely works in a sector from one that lists it among thirty others. Each is checkable on the agency’s own site before you book a call.

• It names this type of client on its own site, rather than listing it as one of thirty verticals.
• SEO is the service being sold, not a bolt-on to a website build.
• Reporting and deliverables are described somewhere a prospect can read them before a sales call.
• Pricing is published, or it is clearly marked custom rather than left vague.

We did not score agencies on review counts or award badges. Both are easy to accumulate and neither tells you whether a team can move the pages that make you money.

Questions a founder should ask before signing

The usual agency questions matter less here than the ones about flexibility and sequencing.

1. What is the shortest commitment you will accept, and what are the exit terms?
2. Which twenty keywords would you target in the first ninety days, and why those twenty?
3. What happens to the strategy if our positioning changes in month four?
4. Who writes the content, and have they worked in this category before?
5. How many links do you expect we need before the wedge is rankable?
6. What would make you tell us to stop spending on SEO?

The last question is the useful one. An agency willing to say that SEO is a poor fit for your situation is an agency worth trusting when it says the opposite.

Pitches that should end the conversation

Most bad SEO engagements are visible in the sales call. These are the signals worth walking away from.

• A guaranteed number one ranking, which no agency can promise because no agency controls the algorithm.
• Refusal to name the publishers, pages or tactics behind link building.
• Reports built entirely on rankings and impressions, with no line connecting to leads or revenue.
• A twelve month contract signed before any audit has been done.
• Work handed to an anonymous team you never speak to after onboarding.

When a startup should not buy SEO yet

SEO is not the right first channel for every company, and an honest agency will say so. Hold off if any of the following is true.

• Nobody is searching for the problem you solve yet, because the category does not exist.
• Your positioning is still changing monthly, so any content written now will be wrong soon.
• You have under six months of runway and need revenue this quarter.
• The product is not ready, so traffic would arrive and churn immediately.

In those cases paid acquisition, outbound or community work will answer faster, and Google Search Central guidance on hiring an SEO is worth reading before you commit to any agency. Our comparison of doing SEO yourself versus hiring an agency is worth reading before you commit a budget either way.

Frequently Asked Questions

How much should a startup spend on SEO?

Spend enough to do one thing properly rather than three things partially. A small budget spread across technical work, content and links usually produces nothing in any of the three. Most agencies on this page will scope a narrow first phase if you ask them to, and Embarque publishes its pricing if you want a reference point before any calls.

How long before a startup sees results from SEO?

On a brand new domain, expect six to twelve months before organic becomes a meaningful acquisition channel, and longer in competitive categories. Low competition long tail queries can move inside three months, which is why a good agency starts there and uses those wins to justify the next phase.

Should we hire an agency or a freelancer?

A freelancer is usually cheaper and fine when you need one capability executed well, such as technical fixes or content. An agency makes more sense when you need strategy, content and link building running together, because coordinating three freelancers becomes a job in itself.

Do we need link building this early?

If you are targeting anything commercial, yes. A domain with no referring domains will not rank against established competitors regardless of content quality. The alternative is to target only very long tail queries until some authority accumulates, which is a slower route to the same place.

Making the call

Bootstrapped and testing the channel, start with Embarque because the pricing is public and the commitment is monthly. Funded and running several channels, Single Grain or NoGood. Selling B2B, Ten Speed. If the blocker is that nobody links to your new domain, that is the specific problem our link building work is built to solve, and you can get pricing without sitting through a call first.
