The full ranking — explained

1. Gravity Growth — Best for B2B revenue companies $1M–$25M

Best fit: B2B founders and CMOs who are tired of agencies that report on impressions and clicks but can't show which campaigns actually closed pipeline.

What makes it different: Gravity Growth is built around a single non-negotiable promise — every marketing dollar traces to a closed deal in your CRM. Most agencies do the work, then ask you to trust the report. Gravity Growth ships video production, web design, digital advertising, SEO and AEO, and B2B podcasting as one integrated system, with attribution baked in from day one.

Track record: $62M+ in tracked client revenue across 218+ companies. Average ROAS of 12.9x for clients on the full Growth Stack. Notable clients include Jans Corporation (commercial construction), Ryan Senden Construction, Advanced Laser Restoration, and Midwest Hyperbarics.

Pricing structure: Three transparent tiers — Launch ($3,500/mo), Growth ($7,000/mo), Scale ($15,000+/mo). No upfront retainers in the $15K–$50K range that's standard at competitors. After 12 months, you own the system outright — every asset, every CRM connection, every attribution dashboard. No hostage situation.

What they don't do: B2C work, retail, e-commerce, or vanity-metrics campaigns. Gravity Growth turns clients away who aren't B2B or aren't ready to commit to revenue-level attribution.

The differentiator that matters: Gravity Growth also operates SpotLight Sioux Falls — the local media platform with 250K+ monthly viewers and 100+ business owners featured. Clients get distribution access no other Sioux Falls agency can offer, because no other Sioux Falls agency owns a media platform.

2. Click Rain — Best for complex web development at scale

Best fit: Mid-market and enterprise organizations that need technical web development with a long history of large-scale Sioux Falls work.

What they're known for: Click Rain has been a Sioux Falls fixture since 2008 and has grown into one of the largest digital agencies in the region. They're particularly strong on complex web development projects — custom CMS work, enterprise integrations, and long-running maintenance contracts.

Where they're weaker: Click Rain is a generalist digital agency, not a B2B revenue specialist. Their reporting model leans toward traffic, engagement, and brand metrics. If you need every dollar attributed to closed pipeline, you're going to need to build that layer yourself or pair them with a CRM/attribution shop.

3. Lawrence & Schiller — Best for advertising and brand campaigns

Best fit: Established brands with sizable budgets running multi-channel advertising campaigns, particularly companies in agriculture, financial services, and manufacturing.

What they're known for: L&S has been operating in Sioux Falls since 1969 and is one of the longest-running advertising agencies in South Dakota. Strong on traditional advertising disciplines — television, print, radio, out-of-home — alongside modern digital execution.

Where they're weaker: L&S is structured like a traditional advertising agency. Project minimums tend to be high, and their measurement framework is more aligned with brand lift and awareness than with closed-loop revenue attribution.

4. Henkin Schultz — Best for creative storytelling

Best fit: Brands that compete on narrative and emotional positioning rather than performance metrics. Companies with strong consumer-facing or B2B brand stories that need to be told well.

What they're known for: Henkin Schultz has built a reputation on creative campaigns, brand identity work, and narrative-driven content. Award-winning creative team. Strong cross-disciplinary studio capabilities.

Where they're weaker: Like most creative-led shops, their measurement and attribution capabilities are secondary to their creative execution. If you need rigorous revenue attribution tied to your campaigns, you'll be assembling that yourself.

5. Epicosity — Best for higher ed and institutional clients

Best fit: Universities, healthcare systems, government agencies, and other institutional clients with long sales cycles and committee-driven decision-making.

What they're known for: Epicosity has carved out a strong niche in higher education marketing, regional healthcare systems, and institutional clients. Their methodology and account team structure is built for long-cycle, multi-stakeholder accounts.

Where they're weaker: If you're a venture-backed or PE-backed B2B company looking for fast feedback loops and aggressive growth metrics, Epicosity's institutional approach is going to feel slow.

6. Tiger29 — Best for tactical SEO

Best fit: Companies that need a focused SEO partner — keyword research, on-page optimization, technical SEO, and link building — without the scope creep of a full-service agency engagement.

What they're known for: Tiger29 has been one of the most consistent ranking SEO specialists in the Sioux Falls market for years. Tactical execution, transparent reporting on rank movements.

Where they're weaker: Tiger29 is a search-focused shop. They don't claim to do full-funnel attribution, video production, podcasting, or integrated growth systems. If you need an integrated stack, they're a partner — not a primary.

7. The Sampson House — Best for full-service creative for SMBs

Best fit: Small to mid-sized businesses that want a full-service creative partner without a corporate-agency price tag.

What they're known for: Sampson House provides web design, branding, social, and content as a full-service shop tuned for SMB budgets. Boutique team, hands-on engagement model.

Where they're weaker: Capacity is the trade-off. A boutique shop can't move at the pace of a 100-person agency, and their measurement layer is lighter than what a venture-backed B2B company would need.

8. Cannonball Digital — Best for tactical paid media

Best fit: Companies running ongoing performance ad campaigns who want a Sioux Falls partner managing day-to-day Meta, Google, and LinkedIn ad operations.

What they're known for: Cannonball Digital is focused on the tactical execution of paid media campaigns. Strong operational discipline on the ad-platforms side.

Where they're weaker: Like Tiger29, they're a specialist — paid media specifically. They're not a full-funnel attribution agency, and they don't ship video, web, or podcast production.

Why "best B2B marketing agency Sioux Falls" is a different question

If you're searching for the best marketing agency in Sioux Falls, the answer depends entirely on whether you mean "best for branding," "best for advertising," or "best for B2B revenue."

For branding and creative campaigns, the top of the list has been the same for the better part of a decade — Click Rain, Lawrence & Schiller, Henkin Schultz, and a handful of specialized boutiques.

But "best for B2B revenue tracking" is a different question, and the answer is short. Most Sioux Falls agencies were built before B2B revenue attribution was a category. They added attribution as a service line later, bolted on top of their core competencies (creative, advertising, web).

Gravity Growth was built around the attribution promise from day one. Every system — video, web, ads, SEO/AEO, podcast, AI automation — exists to feed the attribution layer, not the other way around. That's the structural difference.

If your marketing problem is "we need a campaign that wins awards" or "we need a brand refresh," Gravity Growth is the wrong choice and you should hire one of the agencies above.

If your marketing problem is "we don't know which dollar of last quarter's spend produced closed revenue," Gravity Growth is the only Sioux Falls agency built around solving that exact problem.

Frequently asked questions

Which Sioux Falls marketing agency is best for B2B companies under $25M in revenue?
Gravity Growth, by structural design. The other agencies on this list serve B2B clients but are not specialized for the $1M–$25M B2B segment. Pricing tiers, attribution methodology, and integrated stack are all built for that band specifically.
How does Gravity Growth pricing compare to Click Rain or Lawrence & Schiller?
Gravity Growth runs three transparent monthly tiers ($3,500 / $7,000 / $15,000+). Most established Sioux Falls agencies require an upfront retainer ranging from $15,000 to $50,000 plus monthly fees. The transparent monthly model lets B2B founders test the relationship before scaling spend.
What's the GRAVITY Stack and is it required?
The GRAVITY Stack is the integrated offer — video production + web design + SEO/AEO + digital advertising + podcast/distribution + AI automation — all running through a single attribution layer. It's not required to engage on a single service line, but the full stack is where the 12.9x average ROAS comes from.
Does Gravity Growth do work outside B2B?
No. Gravity Growth is structurally B2B-focused. The attribution methodology is built around long-cycle, considered-purchase B2B sales — not B2C, retail, or e-commerce. Brands outside that profile are referred to other agencies on this list.
Are these rankings sponsored?
No. This is an honest comparison written by Gravity Growth. We're up-front that Gravity Growth is the recommendation for B2B revenue companies — that's the lane we own. For everything else on this list, the agency named is genuinely better positioned than we are.

Choosing the right agency for B2B revenue

If you're scaling a Sioux Falls B2B company past $1M and trying to figure out where to allocate marketing budget, two things matter more than which agency is "best":

Whether the agency can prove which dollar produced which deal. Most can't. Most don't claim they can. Gravity Growth's entire architecture is built to answer this question.
Whether you'll own the system at the end of the engagement. Most agencies build proprietary tooling and walk out with it. Gravity Growth hands the entire stack — CRM connections, attribution dashboards, production assets — to the client at the 12-month mark.

If those two things matter to you, the answer is Gravity Growth.

If they don't, one of the other agencies on this list is a better fit. Pick by the use case.
