MountainGate Capital Taps Upswell to Supercharge Portfolio Growth

MountainGate Capital, the Miami-based private equity firm focused on lower mid-market B2B services companies, has brought in Upswell Marketing to solve a problem most PE firms pretend doesn't exist: their portfolio companies are terrible at generating leads. The partnership, announced this week, puts Upswell's performance marketing team directly in service of MountainGate's holdings — companies that now get access to fractional CMO expertise, demand generation programs, and brand positioning work without the overhead of full-time hires.

It's a bet that measurable marketing — the kind that tracks every dollar spent to every lead generated — can unlock growth faster than operational improvements alone. And it signals where MountainGate thinks the next wave of value creation lives: not in cutting costs, but in filling pipelines.

The partnership comes as MountainGate manages over $500 million in committed capital across its funds, with portfolio companies spanning logistics, professional services, and specialized B2B verticals. Upswell, founded in 2017, specializes in helping service businesses build lead-generation engines — the unglamorous, high-ROI work of SEO, paid media, and conversion optimization that most agencies ignore in favor of brand campaigns.

The deal gives every MountainGate portfolio company immediate access to Upswell's services. No RFPs. No vendor selection committees. Just a direct line to a team that's already been briefed on the fund's value-creation playbook.

For years, PE value creation meant one thing: operational efficiency. Cut costs. Consolidate vendors. Automate processes. Rinse, repeat. Marketing, if it existed at all, was treated as overhead — a cost center to be minimized, not a growth lever to be pulled.

That calculus is shifting. Lower mid-market firms especially are discovering that their portfolio companies can't just optimize their way to exits. They need to grow revenue. And in B2B services — where MountainGate plays — that means generating qualified leads at scale.

The numbers back this up. According to Bain & Company research, commercial excellence — sales and marketing optimization — now accounts for 30-40% of value creation in services-focused buyouts, up from less than 20% a decade ago. PE firms that once hired operational consultants are now hiring growth marketers.

MountainGate's move with Upswell is part of that trend, but with a twist. Instead of building an in-house marketing function or forcing each portfolio company to hire its own CMO, the firm is centralizing expertise. Upswell becomes the shared service layer — deployed wherever the need is greatest, scaled up or down as companies enter or exit the portfolio.

Upswell isn't a brand agency. It's not going to redesign logos or shoot lifestyle commercials. Its specialty is performance marketing — the discipline of turning marketing spend into measurable pipeline growth.

That means SEO audits to make sure portfolio companies actually show up when prospects search for their services. Paid media campaigns on Google and LinkedIn calibrated to cost-per-lead targets. Landing page optimization to convert traffic into form fills. Email nurture sequences that move cold leads to qualified opportunities.

For a PE firm, this is gold. Every dollar Upswell spends is tied to a lead. Every lead is tracked through the CRM. Every campaign has a clear ROI calculation. It's the kind of marketing finance teams can actually understand — and value.

The partnership also solves a talent problem. Most lower mid-market companies can't afford a senior marketing leader. And even if they could, that hire would spend half their time managing agencies and vendors rather than doing the work. Upswell collapses the agency and the leadership role into one package.

Here's how MountainGate and Upswell describe the collaboration: When MountainGate closes a new deal, Upswell conducts a rapid marketing assessment within the first 90 days. That includes a website audit, competitive positioning review, lead generation infrastructure check, and a 12-month growth roadmap tied to the portfolio company's revenue targets.

MountainGate Capital was founded in 2019 by Luis Casamayor and focuses on acquiring founder-owned B2B services businesses in the lower mid-market — typically companies doing $10-50 million in revenue. The firm's target sectors include logistics, professional services, specialized manufacturing services, and tech-enabled services.

These are businesses that often have strong unit economics and loyal customer bases but lack formal sales and marketing functions. The founder is usually the chief salesperson. Lead generation happens through referrals and word-of-mouth. There's no CRM, no marketing budget, and no one tracking customer acquisition costs.

That's the opportunity. MountainGate's thesis is that these companies can scale rapidly if you professionalize their go-to-market motion. And marketing is the first lever to pull — it's faster than hiring a sales team, cheaper than opening new locations, and more predictable than waiting for organic growth.

The Upswell partnership institutionalizes that approach. Instead of each portfolio company figuring out marketing on its own — or worse, not figuring it out at all — MountainGate can deploy a proven playbook from day one.

It also creates a data advantage. As Upswell works across multiple MountainGate companies, the firm accumulates benchmarks: what cost-per-lead looks like in logistics versus professional services, which channels convert best for different business models, how long it takes to see ROI from SEO versus paid media. That institutional knowledge compounds with each new deal.

MountainGate isn't the first PE firm to experiment with shared services for portfolio companies, but marketing has historically been one of the least centralized functions. Finance? Sure. HR and benefits? Increasingly common. IT infrastructure? Absolutely. But marketing has always been seen as too company-specific, too creative, too hard to standardize.

Upswell's approach challenges that assumption. Performance marketing — especially in B2B services — is more science than art. The tactics that work for a logistics company aren't that different from those that work for a professional services firm. Both need SEO. Both need paid search. Both need lead nurture. The messaging changes, but the machinery doesn't.

The MountainGate-Upswell deal is a signal of where value creation is heading in the lower mid-market. As purchase price multiples stay elevated and interest rates keep debt expensive, PE firms are under pressure to drive organic growth — not just financial engineering.

That's particularly true for firms like MountainGate that focus on founder-owned businesses. These companies rarely have professional management teams in place. The founder knows the business cold but has never built a repeatable sales process or thought strategically about customer acquisition. Post-close, the PE firm has to professionalize everything at once.

Marketing used to be third or fourth on that list. Now it's first. Because if you can't generate leads, you can't grow revenue. And if you can't grow revenue, you can't justify a step-up multiple at exit.

The partnership also highlights a broader shift in how PE firms think about expertise. The old model was to hire consultants project-by-project or expect portfolio company management to figure things out. The new model is to build or partner with specialist firms that can deliver consistent, repeatable outcomes across the portfolio.

MountainGate isn't alone in rethinking marketing's role in value creation. Vista Equity Partners has a dedicated marketing consulting arm that works across its software portfolio. Accel-KKR has hired CMOs-in-residence who rotate through portfolio companies. Even smaller firms are experimenting with fractional marketing leadership or preferred agency partnerships.

What makes the MountainGate approach distinctive is its focus on the lower mid-market, where companies have less infrastructure to build on and fewer resources to experiment. Upswell has to deliver results fast — ideally within the first year — or the portfolio company won't see the ROI.

Not every shared services model works. And marketing is particularly vulnerable to misalignment between the PE firm's priorities and the portfolio company's needs.

The biggest risk is that Upswell becomes a top-down mandate rather than a bottom-up resource. If portfolio company CEOs feel like MountainGate is forcing them to work with a specific agency, resistance is inevitable. Marketing only works when the internal team — sales, operations, leadership — is bought in. If they see Upswell as an outsider parachuted in by the sponsor, campaigns will stall.

There's also the scaling question. Upswell is a boutique agency, not a global consultancy. If MountainGate's portfolio grows rapidly — or if Upswell takes on similar partnerships with other PE firms — can it maintain quality? Or does it become another vendor stretched too thin?

And then there's the measurement problem. Marketing attribution is notoriously messy, especially in B2B services where sales cycles can last months and deals often close through relationships rather than inbound leads. If Upswell can't prove clear ROI, the partnership won't survive past the first few portfolio companies.

If the MountainGate-Upswell partnership delivers — meaning portfolio companies see measurable lead growth and faster revenue expansion — expect other lower mid-market PE firms to copy the playbook. The economics are too compelling: centralized marketing expertise at a fraction of the cost of full-time hires, with results that show up in the next quarterly review.

The real test will be exit multiples. If MountainGate can point to portfolio companies that scaled revenue 30-50% faster because of Upswell's work, that becomes a competitive advantage at fundraising time. Limited partners want to see differentiated value creation strategies. "We have a marketing partner" isn't sexy, but "we systematically professionalize go-to-market and accelerate pipeline growth" is.

It also raises a bigger question: What other functions in PE portfolio companies are ripe for this kind of centralization? If marketing can be shared across companies, what about sales enablement? Customer success? Product management? The lower mid-market has long been a laboratory for lean operations. Now it's becoming a laboratory for shared growth infrastructure.

For now, MountainGate has made a bet that most PE firms talk about but few execute: that the fastest path to value creation isn't in the back office, but in the front office — where leads turn into revenue and revenue turns into exits.

MountainGate Capital's partnership with Upswell Marketing is a tactical move with strategic implications. On the surface, it's a PE firm hiring a marketing agency. Dig deeper, and it's a thesis about where value creation happens in the 2025 buyout market: not in cost-cutting, but in revenue acceleration. Not in operational efficiency, but in commercial excellence.

Whether it works depends on execution. Can Upswell scale across a growing portfolio without losing effectiveness? Will portfolio company CEOs embrace the partnership or resist it? Can the firm prove that marketing dollars directly drive enterprise value?

If the answer to those questions is yes, MountainGate will have built a repeatable growth engine that most lower mid-market firms are still figuring out. If not, it's just another vendor relationship that sounded better in the press release than it plays out in practice.

Either way, the move signals where the industry is heading. Private equity firms are no longer just buying companies and optimizing them. They're building them. And building requires marketing that actually works — not the kind that looks good in a deck, but the kind that fills pipelines, closes deals, and justifies exit multiples.
