San Francisco has more B2B marketing agencies than most buyers can reasonably evaluate. The hard part is not finding one. It is figuring out which kind of agency your company needs right now, because a brand studio, a website builder, an SEO firm and a pipeline partner solve very different problems.
This list groups eleven San Francisco and Bay Area agencies by what they actually do, based on what each one publishes on its own website. We kept the original 2026 list where firms checked out and replaced two that we could not confirm as San Francisco B2B agencies.
Disclosure: this list is published by Lemniscate Growth, which is included. Last checked: September 2026.
How we chose
We looked for agencies a San Francisco B2B technology company could realistically shortlist in 2026. Each firm had to meet these criteria:
- Currently operating, with a working website we reviewed during this update.
- A San Francisco or Bay Area presence, stated on its own site, or in Lemniscate's case, a dedicated San Francisco program with a remote team.
- Clear relevance to B2B marketing: pipeline, search and AI visibility, content, communications, brand, web, product UX or media.
- A specialty that is easy to explain, so buyers can match the firm to a specific problem.
- Services and focus described specifically enough on the firm's site to evaluate without guessing.
Inclusion is based on what each firm publishes on its own site. We did not use ratings, awards or pricing, and we do not publish any agency's fees.
1. Lemniscate Growth
Lemniscate Growth is a B2B revenue pipeline generation agency. It works across the funnel, with AEO, GEO and SEO as a core service alongside outbound and content, and it reports on pipeline rather than traffic alone. It runs more than 35 active client programs and targets up to $10M in pipeline per client. The company is registered in the US and Dubai, with its team in Hyderabad.
For SaaS buyers, the Aavenir case study is a useful reference: a contract lifecycle management product on ServiceNow where 90 to 95% of results come from inbound search. The IQLECT case study shows $6.4M in pipeline from organic.
Best for: San Francisco B2B tech companies, from Series A to enterprise, that want one partner accountable for qualified pipeline.
Services: SEO, answer engine optimization, generative engine optimization, content, outbound and pipeline reporting.
Why it made the list: It is our own firm, so weigh this entry with that in mind. It fits teams that measure marketing by pipeline and want search, AI visibility and outbound run as one program. It is not the right choice for brand identity projects, large paid media buys, or teams that want an agency in the room in San Francisco every week.

2. Growth Marketing Pro
Growth Marketing Pro is a growth agency for fast-growing tech and SaaS companies, with locations listed in San Francisco, San Diego and Boston. Its site describes a "Search Everywhere Optimization" approach that extends search work to Reddit, YouTube and Quora, and it lists generative engine optimization as a service. It says clients work directly with senior operators rather than junior account managers.
Best for: Startups and growth-stage SaaS teams that want one agency across organic search, paid acquisition and conversion.
Services: SEO, GEO, paid media on Google, Meta and LinkedIn, content strategy, conversion rate optimization, Reddit marketing, link building and digital PR, web development.
Why it made the list: Few agencies of its size combine paid, organic and community channels like Reddit under one roof, which suits companies whose buyers research on forums as much as on Google.
3. Tendo Communications
Tendo Communications is a B2B content agency on Mission Street in San Francisco. Its site focuses on large B2B enterprises with complex sales cycles and multiple decision-makers. The work spans content strategy, production and the operations that keep a large content program running, and it publishes thinking on brand discoverability in AI-driven search.
Best for: Enterprise B2B marketing teams that need a content program with strategy, governance and measurement, not just more articles.
Services: Content strategy and planning, content creation, content operations, content performance, user experience services and an editorial content studio.
Why it made the list: Content operations is a real bottleneck for large B2B teams, and Tendo is one of the few San Francisco agencies built specifically around it.
4. Mortar
Mortar is an advertising and brand agency based in Daly City, just south of San Francisco. It works across healthcare, technology, education and consumer experiences, and its site pairs brand work with marketing strategy, media and measurement. Its site does not describe AI search services, so ask about that directly if it matters to you.
Best for: Companies that need brand identity, positioning and campaign creative, especially after a pivot, merger or category change.
Services: Identity and branding, creative development, marketing and communications strategy, messaging and positioning, media planning and buying, research, measurement and analytics.
Why it made the list: Weak positioning undermines every channel. Mortar covers the brand and messaging layer that pipeline agencies usually do not.
5. Baunfire
Baunfire is a Silicon Valley digital agency with an office in downtown San Jose. It says it works with established brands and startups in Silicon Valley, and its site and blog lean toward B2B and SaaS topics such as conversion rate optimization and SEO.

Best for: B2B tech companies planning a website redesign or replatform that has to support both brand and conversion goals.
Services: Website design and development, UX, creative and marketing asset design, strategy.
Why it made the list: Your website is the page AI engines and buyers both land on. Baunfire is a Bay Area specialist for getting that build right.
6. Neuron
Neuron is a UX and UI design agency on California Street in San Francisco. It specializes in enterprise software and B2B products, including analytics, CRM, finance and HR platforms, and lists AI interface design among its services. It is a product design partner rather than a marketing agency in the traditional sense.
Best for: Product-led and hybrid SaaS companies where trial, onboarding or in-product experience is limiting conversion.
Services: Product strategy, UX and UI design, UX audits, wireframing and prototyping, data visualization, AI interface design, design systems, usability testing, accessibility design, DesignOps and front-end engineering.
Why it made the list: In product-led motions, the product is part of marketing. Neuron addresses the experience that turns sign-ups into pipeline.
7. AdLift
AdLift is a search and digital marketing agency with a US office in Burlingame, near San Francisco International Airport, and offices in Gurugram, Mumbai and Bengaluru. Its site lists AI SEO, LLM optimization, GEO and AEO alongside traditional SEO.

Its site describes an "outcome-based marketing" approach that starts with business outcomes before choosing channels.

Mediasmith describes itself as an independent media agency. Its site lists an Oakland address and a San Francisco phone line. It plans and buys paid media across social, audio, video, out-of-home and LinkedIn, and it lists SaaS and financial services among the industries it serves.
Best for: Well-funded B2B companies running significant paid media that want independent planning and buying outside a holding company network.
Services: Media strategy, media planning and buying across social, audio, video, out-of-home and LinkedIn, and media analytics.
Why it made the list: When paid media budgets grow, a dedicated media agency usually outperforms a generalist, and independence matters to buyers who want unconflicted recommendations.
10. Victorious
Victorious is an SEO agency that lists a San Francisco address. Its site organizes its offer around SEO, answer engine optimization, content and technical SEO. It names the AI platforms it optimizes for, including ChatGPT, Perplexity, Google AI Overviews, Gemini, Copilot and Claude, and it lists B2B, SaaS, enterprise, finance and AI companies among its segments.

How to choose a B2B marketing agency in San Francisco
Match the agency type to the problem
Write down the one problem costing you the most revenue before you take a single call. If deals stall because nobody knows you, you need visibility and pipeline work. If buyers visit and leave, you likely need web or product UX. If your story sounds like five competitors, start with brand and positioning.
Your go-to-market motion matters too. Sales-led companies usually need a pipeline partner focused on target accounts and search demand. Product-led companies often get more from product UX and conversion work. Hybrid motions need both, which is why many San Francisco teams run one pipeline partner plus one specialist.
Plan for AI answer engines
Technical buyers increasingly ask ChatGPT, Claude, Perplexity and Gemini for vendor shortlists, and Google shows AI-generated answers on many research queries. Those answers draw on pages that state clear facts: comparison pages, documentation, pricing and integration pages, third-party reviews and community threads.
That changes what you should ask an agency. Rankings still matter, but so does how often your brand is named and cited in AI answers for the prompts your buyers actually use. Our guide on how to benchmark AI visibility explains how to measure this, and the AEO and GEO playbook covers the work behind it. For a San Francisco search partner specifically, see our San Francisco SEO, AEO and GEO page.
Insist on attribution you can check
Agree on definitions before signing: what counts as a marketing qualified lead, a sales accepted opportunity and sourced versus influenced pipeline. Then confirm the agency will report from your CRM, not from its own dashboard. An agency that cannot connect its work to opportunities in Salesforce or HubSpot is asking you to trust it on faith.
Account for California privacy law
The California Consumer Privacy Act, as amended by the CPRA, is enforced by the California Privacy Protection Agency. Per the agency's FAQ, the exemptions for business-to-business and employee personal information expired on December 31, 2022. It applies to for-profit businesses that meet at least one threshold, such as annual gross revenue of $26.625 million or more (as of January 1, 2025) or buying, selling or sharing personal information of 100,000 or more California consumers or households.
For marketing, that touches form fills, contact enrichment, intent data, ad pixels and retargeting. Ask any agency how it handles consent, opt-outs and data shared with third-party tools, and confirm your obligations with your own counsel.
Questions to ask on the first call
- Which of our problems are you best suited to solve, and which should we hire someone else for?
- Who will do the work every week, and how much of it is senior time?
- How will you report results from our CRM, and how do you define sourced and influenced pipeline?
- Which AI answer engines and prompts will you track for us, and how do you measure mentions and citations?
- What will you need from our product, sales and engineering teams, and how many hours a month is that?
- What should we expect to see at 30, 90 and 180 days?
- How do you handle consent, opt-outs and data sharing under California privacy law?
- How are fees scoped, and what happens if we want to change scope or exit?
- Can we speak with a current client whose company and motion look like ours?
Red flags
- Guaranteed rankings, guaranteed AI citations or a fixed number of leads before they have seen your data.
- Reporting built on traffic, impressions or follower counts with no link to opportunities.
- A pitch led by senior partners, followed by delivery handed to people you never met.
- Claims to do everything well, from brand identity to outbound to media buying, with no clear specialty.
- No written view on how AI answer engines affect your category.
- Long lock-in contracts with no performance review points.
- Vague answers about where your contact and visitor data goes.
