Bridge Growth Closes $790M Continuation Vehicle for Solace

Bridge Growth Partners just closed a $790 million continuation vehicle for Solace, the event-streaming software company it's held since 2019. Four institutional investors — Apogem Capital, Golub Capital, HSBC Asset Management, and Schroders Capital — led the vehicle, which lets Bridge extend its ownership while giving existing limited partners a liquidity option.

The deal marks one of the larger continuation vehicles this year for a mid-market software asset. Bridge originally backed Solace through its second fund, which is now seven years into its life. Rather than push for an exit into a tepid M&A market or an IPO window that remains mostly shut for infrastructure software, the firm opted to reset the clock with fresh capital and new institutional backing.

Continuation vehicles have become the preferred tool for private equity firms stuck between holding periods that are stretching and exit markets that aren't cooperating. For software companies specifically, the calculus has shifted: valuations that looked expensive in 2021 now look reasonable in 2026, but strategic buyers remain cautious and public market comps haven't recovered enough to justify exits at the prices LPs were promised.

Solace sells event-streaming infrastructure — the plumbing that moves real-time data between applications, systems, and devices. It competes in a space dominated by Apache Kafka and adjacent to players like Confluent and AWS Kinesis. The company's pitch centers on hybrid cloud deployments and use cases where latency and reliability matter more than raw throughput: financial services trading systems, logistics tracking, IoT networks.

The composition of the investor group is notable. Apogem Capital, Golub Capital, HSBC Asset Management, and Schroders Capital don't typically co-lead continuation vehicles together. Golub is best known as a direct lender; HSBC Asset Management and Schroders are insurance-linked and pension-backed capital pools; Apogem is a relatively newer secondaries-focused firm.

What they share: a willingness to underwrite extended hold periods on software assets where the growth story is intact but the exit path is murky. Continuation vehicles at this scale typically require conviction that the next three to five years will generate better returns than selling today. That means the investors believe Solace's revenue growth, margin expansion, or strategic positioning will improve enough to justify waiting.

Bridge didn't disclose Solace's current revenue or valuation, but the size of the vehicle suggests the company is likely doing $100 million to $200 million in annual recurring revenue. Event-streaming infrastructure companies at that scale typically trade at 8x to 12x revenue in private markets today, down from 15x to 20x multiples in 2021. If Solace is growing 25% to 35% annually and approaching breakeven or profitability, the valuation math starts to work for a continuation vehicle.

The deal also reflects a broader shift in how continuation vehicles are being used. Early iterations were often rescue mechanisms — ways to avoid marking down a troubled asset or forcing a fire sale. Now they're deliberate extensions for assets that are performing but mistimed. Solace fits that profile: a functional business in a real market that's trapped between a rocky IPO environment and a strategic M&A market that's repricing software infrastructure downward.

Solace operates in a category that benefited enormously from the 2020-2021 digital transformation spending boom and then got hammered when enterprises slammed the brakes on cloud budgets in 2022-2023. Event-streaming infrastructure is expensive to deploy, complex to operate, and often the first thing CIOs defer when they're told to cut costs.

But the category didn't collapse — it consolidated. Kafka remains the open-source default, Confluent went public and has spent three years trying to prove it can build a profitable business on top of it, and cloud providers have embedded their own event-streaming services into their platforms. Solace's survival in that squeeze suggests it's defending a specific niche: customers who need multi-cloud or hybrid deployments and are willing to pay for a vendor that isn't AWS, Azure, or Google.

The company's customer base skews toward industries where event-streaming is non-negotiable: financial services firms running trading platforms, airlines coordinating logistics networks, manufacturers tracking IoT sensors across factories. These aren't discretionary workloads. They're the kind of infrastructure that survives budget cuts because turning it off breaks critical operations.

The table above shows how dramatically software infrastructure valuations have compressed. Solace is likely valued today at roughly half what it would have commanded in 2021, even if its revenue has grown 60% to 80% since then. That's the math that makes continuation vehicles attractive: rather than sell at a depressed multiple, hold until either multiples recover or the company grows into a valuation that works at today's pricing.

Event-streaming infrastructure sits below the application layer and above raw compute and storage. It's the messaging bus that connects microservices, synchronizes data across distributed systems, and enables real-time analytics. Companies like Solace compete on latency, reliability, and deployment flexibility rather than raw feature breadth.

Bridge Growth Partners raised its second fund in 2017-2018, which means it's now outside the typical five-to-seven-year hold period that LPs expect. The Solace continuation vehicle is a signal that Bridge believes it can generate better returns by holding longer rather than exiting into current market conditions.

This isn't a novel strategy anymore. Continuation vehicles raised by U.S. private equity firms hit $30 billion in 2024 and are on pace to exceed $35 billion in 2025, according to data from Evercore and Jefferies. The majority are concentrated in software, healthcare IT, and business services — categories where growth assumptions from 2019-2021 vintage funds haven't materialized on the timelines that were underwritten.

For LPs in Bridge's original fund, the continuation vehicle offers a choice: roll into the new vehicle and stay invested, or take liquidity at whatever valuation Bridge and the new investors negotiated. LPs who need distributions will take the exit. LPs who believe in the long-term thesis and don't need cash will roll. The ones who roll are betting that Bridge can double the equity value over the next four to five years.

That's a steep bar. Solace would need to either grow revenue significantly faster than it has, expand margins to levels that make it attractive to strategic acquirers, or time an exit into a market where software infrastructure multiples have recovered. None of those are guaranteed. But the alternative — selling today into a buyer's market — likely leaves money on the table that Bridge believes it can capture by waiting.

The decision to bring in four institutional investors rather than a single large secondaries buyer also suggests Bridge wanted validation from multiple sources that the valuation and thesis were sound. Secondaries buyers are typically more aggressive on pricing — they're buying discounted positions and betting on mark-to-market gains. Institutional investors co-leading a continuation vehicle are underwriting the business itself, not just the discount.

Continuation vehicles typically involve Bridge Growth rolling its equity into a new fund structure, with the four institutional investors providing the $790 million in fresh capital. That capital goes to buy out LPs who want liquidity and to fund the next phase of growth at Solace — whether that's product development, sales expansion, or M&A.

Bridge likely retained a significant equity stake, and the four institutional investors now own the majority alongside them. The deal resets the fee clock — Bridge collects management fees on the new vehicle, and the carry hurdle resets based on the new valuation. For the institutional investors, the thesis is simple: buy into a software company at a post-correction valuation, hold it through the next growth phase, and exit when markets stabilize.

One of the reasons continuation vehicles are proliferating is that strategic buyers — the companies that typically acquire infrastructure software assets — are moving slowly. Oracle, Cisco, IBM, and Salesforce have all been active acquirers historically, but their M&A appetite has cooled as they focus on integrating past deals and managing their own margin pressures.

For a company like Solace, the natural strategic buyers would be cloud providers (AWS, Microsoft, Google) or enterprise software vendors building out event-streaming capabilities. But those buyers are increasingly building rather than buying, especially for infrastructure components where they can bundle features into existing platforms rather than pay a premium for a standalone vendor.

That leaves private equity-backed companies like Solace in a holding pattern. They're too large and mature to be attractive venture acquisitions, too subscale to go public alone, and not strategically essential enough to command premium M&A multiples. Continuation vehicles are the answer to that timing problem.

The bet is that either strategic buyer appetite returns in 2027-2028, or that Solace grows large enough to go public on its own terms. Both are plausible but not certain. The IPO market for infrastructure software has been dead since 2021 — Confluent, HashiCorp, and GitLab all went public in that window, and all have struggled to maintain their valuations. Solace would need to demonstrate significantly stronger unit economics or a clearer path to profitability to attract public market investors.

From an LP perspective, continuation vehicles are a mixed outcome. On one hand, they provide liquidity when exits aren't available. On the other hand, they force LPs to either accept a below-expectation exit price or double down on an investment that's already older than planned.

LPs who roll into the new vehicle are effectively extending their lock-up period by another four to six years. That's fine for institutional investors with long time horizons, but it's a problem for endowments, family offices, or funds-of-funds that have their own liquidity needs. The LPs who exit are taking whatever price Bridge negotiated with the new investors, which is likely below what they expected when they committed capital in 2017-2018.

The tension here is that continuation vehicles shift power from LPs to GPs. Bridge Growth controls the timing, the valuation, and the terms of the new vehicle. LPs can opt in or out, but they can't force an exit at a price they prefer. That dynamic is changing LP expectations around fund life, exit timelines, and liquidity rights — all of which will shape how future fund agreements are negotiated.

Some LPs are pushing back by demanding more transparency, shorter fund lives, or earlier liquidity options. Others are accepting that extended holds are the new normal in software and infrastructure assets where growth slowed but didn't collapse. The next generation of fund agreements will likely include more explicit provisions around continuation vehicles and LP consent thresholds.

The immediate question for Solace is whether it can accelerate growth now that it has fresh capital and a longer runway. The company will likely use the $790 million to fund product development, expand sales teams, and potentially acquire smaller competitors or complementary technologies.

Event-streaming infrastructure is a category where scale matters. Larger vendors can offer broader integrations, more deployment options, and better support for multi-cloud environments. Solace's customer base is strong in financial services and logistics, but it needs to expand into other verticals — healthcare, retail, manufacturing — to reach the scale that makes it attractive to strategic buyers or public market investors.

The company also needs to demonstrate margin improvement. Infrastructure software companies are increasingly valued on free cash flow rather than pure revenue growth. If Solace is still burning cash or operating at low margins, it won't matter how fast it's growing — buyers and investors will discount the business accordingly.

For the four institutional investors, the timeline is straightforward: hold for four to five years, work with Bridge to professionalize the business, and exit into either a strategic acquisition or a secondary sale to another private equity firm. The ideal outcome is a strategic acquisition at 12x to 15x revenue, which would generate a solid return on the $790 million even if Solace only grows modestly from here.

The less ideal outcome is that event-streaming infrastructure gets commoditized by cloud providers, Solace's growth stalls, and the business ends up worth roughly what it's valued at today. That's the risk the investors are taking by underwriting another five years of hold time in a category where the competitive dynamics are shifting.

The Solace continuation vehicle is a template for what's coming across the private equity industry. Hundreds of software companies backed between 2018 and 2021 are now approaching the end of their fund lives, and most won't exit at valuations that satisfy their LPs. Continuation vehicles are the pressure release valve.

The firms most likely to use continuation vehicles are mid-market growth equity investors — exactly where Bridge Growth sits. These firms backed companies at 15x to 25x revenue multiples when capital was cheap and growth was fast. Now those companies are worth 8x to 12x revenue even if they've doubled in size. Selling today crystallizes a loss. Holding another five years offers a chance to grow into the original valuation or wait for multiples to recover.

The risk is that multiples don't recover and growth slows further. Software infrastructure is being repriced downward not just because of interest rates and macro conditions, but because the category itself is maturing. Event-streaming, observability, data warehouses, and API management are all becoming commoditized by cloud providers. Standalone vendors need to prove they offer something a hyperscaler can't bundle for free.

Solace's next five years will be a test of whether that's possible. If the company can defend its niche, grow profitably, and time an exit into a better market, Bridge Growth and its institutional backers will look smart. If not, this continuation vehicle becomes another data point in the long, slow repricing of software infrastructure.
