Touchstone Partners founding team
Touchstone Partners, a Vietnam-focused climate-tech venture firm, has made a partial exit from Stride, a distributed solar platform for households and micro, small and medium-sized enterprises (MSMEs) in Vietnam, following the startup’s successful Series B raise.
Stride closed a US$15 million Series B co-led by Lightrock and TRIREC via the Accelerate7 platform, with existing backers Clime Capital’s SEACEF II and UOB Venture Management’s Asia Impact Investment Fund II also reinvesting. The financing has prompted at least one early investor to monetise part of its holding, reflecting growing interest in commercial-scale distributed solar in Southeast Asia.
A quick backstory
Touchstone and Clime Capital co-led Stride’s US$2 million seed round in 2023, among the earliest institutional bets on Vietnam’s residential distributed solar market. Since then, Touchstone, which specialises in climate-tech and impact-driven businesses, says it has provided strategic support, fundraising help and introductions to policy and corporate stakeholders while working alongside Stride’s founding team.

Stride’s footprint has expanded substantially: the company now claims operations across north, central and south Vietnam, supported by more than 75 verified engineering, procurement and construction (EPC) subcontractors. Touchstone says Stride has nearly tripled its project portfolio since the seed round and has become Vietnam’s largest platform for residential solar installations.
Why the partial exit matters
Partial exits from early-stage venture funds are noteworthy for several reasons. For limited partners, they provide realised returns and proof that the fund can return capital; for the fund, they free up deployment capacity to back new opportunities. For the market, such exits signal maturation: capital is being recycled from early backers into new deals within the same ecosystem.
“Since we have invested, the company has grown 7.25x in valuation,” Tu Ngo, General Partner at Touchstone Partners, said in a statement. She framed the exit as validation of Touchstone’s thesis that locally built climate solutions can generate both commercial returns and emissions impact, a claim consistent with rising investor appetite for Southeast Asia climate plays.
The figures behind the headline
Stride’s Series B of US$15 million is a meaningful vote of confidence from international and regional investors. Lightrock, a global investor that has backed climate and health tech, and TRIREC, an investment vehicle that uses the Accelerate7 platform,co-led the round. The participation of Clime Capital and UOB Venture Management, both of which reinvested, underscores continued support from regionally focused impact investors.
Touchstone’s partial sell-down comes after a 2023 seed investment of US$2 million that helped Stride scale its operations. Touchstone did not disclose the exact quantum of capital realised in the partial exit, nor the post-money valuation implied by the Series B, standard practice when exits involve negotiated secondary purchases.
What this says about Vietnam’s distributed solar market
Vietnam sits at an inflexion point in distributed renewable energy. Rising energy demand, frequent grid constraints, and a policy environment increasingly focused on decarbonisation have created fertile ground for rooftop and small-scale solar models. However, deployment has long been held back by financing, standards, and fragmented supply chains.
Stride’s model, a marketplace-style platform that aggregates EPC partners and focuses on households and MSMEs, tackles two of those constraints: professionalising installation supply and simplifying customer acquisition. Growing to a network of more than 75 vetted EPC subcontractors suggests the company has solved at least some of the operational challenges that often plague fragmented markets.

Yet the market is not without risks. Household and MSME adoption depends on affordable financing, stable incentives, and consumer trust in installation quality and after-sales service. The participation of a range of investors in the Series B indicates confidence in Stride’s ability to manage these risks. Still, competition from utilities, specialised solar providers and other platforms will intensify as capital flows into the space.
Investor strategy and sectoral signal
Touchstone’s move also reflects a broader pattern among early-stage climate funds in Southeast Asia: backing local founders through product-market fit and early scaling, then recycling capital as winners consolidate. By partially exiting a portfolio company after a successful institutional round, the firm increases its dry powder to chase adjacent opportunities in mobility, energy efficiency, clean production and other climate-tech verticals.
Touchstone’s portfolio includes companies such as Selex Motors and Enfarm, positioning the fund across mobility and agri-tech as it seeks to capture multiple vectors of the green transition in Vietnam. The firm also runs the Net Zero Challenge with Temasek Foundation, an initiative intended to bridge funding gaps for green-economy startups, further signalling its role as a catalytic investor in the local climate ecosystem.
What remains unanswered
Important operational and financial details around Stride were not disclosed in the announcement. Key unknowns include:
- The precise amount Touchstone realised from the partial sale.
- Stride’s revenues, profitability metrics or unit economics on residential and MSME installs.
- The company’s roadmap for growth outside Vietnam, if any, and capital allocation plans following the Series B.
These gaps matter for assessing whether Stride’s growth is primarily driven by demand or by favourable capital markets. They also affect how one reads the exit: validation of a durable business model versus a timely secondary sale enabled by strong investor appetite for climate-linked growth stories.
Broader implications for the region
Southeast Asia has become a target for climate-first capital, with distributed solar an obvious entry point. Solar complements other decarbonisation strategies and can be deployed rapidly compared with large grid-scale projects, making it attractive to both impact and growth investors.
The participation of global and regional players in Stride’s round underscores two trends. First, foreign capital is comfortable backing Vietnam’s climate startups when founders demonstrate scalable operations and clear go-to-market strategies. Second, re-investment by existing regional funds signals belief in the company’s execution, not merely a de-risking by new entrants.
What to watch next
- How Stride deploys the new capital: whether it focuses on deeper penetration in Vietnam, moves upmarket to commercial and industrial clients, or invests in financing solutions for customers.
- The competitive response: whether utilities and incumbent solar installers consolidate or partner with platforms like Stride.
- Follow-on exits: whether Touchstone and other early backers exit further as Stride matures toward eventual larger liquidity events.

For now, Touchstone’s partial exit is a modest but useful data point: investors are willing to both fund and monetise distributed solar bets in Vietnam, suggesting the sector is moving from pilot phase toward commercial scale. That, in turn, could accelerate a wave of follow-on funding and operational consolidation across Southeast Asia’s rooftop solar market.
