A San Francisco startup founded by former project financiers is replacing spreadsheets, email, and PDFs with software - one loan at a time.
Every solar farm, battery storage facility, and community wind project needs financing before it needs anything else. For decades, that financing has moved slowly, passed hand to hand between lenders, developers, and lawyers through email threads and shared spreadsheets. Banyan Infrastructure, a company built by people who spent years inside those deals, makes software meant to fix that plumbing.
The company describes itself as an end-to-end platform for project finance - covering the full arc from sourcing and underwriting a deal, through closing, to years of ongoing portfolio and compliance management. It is not trying to originate capital itself. It is trying to remove the friction that keeps capital that already wants to move from moving faster.
Project finance deals for renewable energy and other sustainable infrastructure are typically tracked across disconnected tools - inboxes, spreadsheets, PDFs. Banyan says this manual process can cost up to 1,000 hours of work per loan, slowing down deals that both sides already want to close.
Banyan's platform digitizes the workflow: automated data ingestion, standardized underwriting templates, covenant and compliance tracking, and shared "collaborative data rooms" where lenders, developers, and investors work from the same live data.
Banyan's customers sit on both sides of a renewable energy financing table: banks and institutional lenders who write the checks, and project developers and owners who need the capital. Green banks and community investment funds - public-purpose lenders focused on climate and clean energy - are also part of its customer base. Reported deal sizes on the platform tend to run in the $1 million to $5 million range, the kind of mid-market financing that is often too labor-intensive to process profitably by hand.
The problems Banyan solves are unglamorous but expensive: reconciling deal data scattered across parties, chasing down compliance documents after a loan closes, and rebuilding reporting templates for every new deal instead of reusing standardized ones. Left unaddressed, these frictions raise the cost of financing small and mid-size renewable projects to the point where some simply don't get funded.
Workflow tools and standardized templates for sourcing renewable energy deals and running underwriting analysis.
A centralized view across a lender's or investor's full portfolio of infrastructure assets, with automated performance and impact metrics.
Automated monitoring of loan covenants and regulatory reporting requirements, with proactive alerts when a deal drifts out of compliance.
| Model | B2B software-as-a-service, licensed to banks, lenders, and developers on a subscription basis by usage and feature tier. |
| Market Position | Positions itself as purpose-built for project finance, rather than a generic deal-tracking or CRM tool adapted to the sector. |
| Differentiation | Built by former project financiers rather than pure software engineers - the founding team says its underwriting and compliance templates reflect real deal structures, not generic workflow software. |
| Sector Focus | Sustainable infrastructure specifically: solar, wind, storage, and related renewable projects, as opposed to infrastructure finance broadly. |
Most competing options in this space are not purpose-built rivals so much as general-purpose tools bent to fit - spreadsheets, shared drives, or CRM and data-room software repurposed for deal tracking. Banyan's argument is that project finance has specific enough needs - covenant structures, impact metrics, multi-party compliance - that a dedicated platform beats a general one.

Banyan Infrastructure sits at the intersection of climate tech and fintech - a category sometimes called "climate fintech." Its customers are not consumers but the institutions that decide which renewable projects get built: banks, green banks, and developers negotiating financing terms. The company frames its mission around a widely cited estimate that renewable infrastructure faces a $3.5 trillion annual global financing gap, positioning its software as a tool for closing that gap through speed and standardization rather than by supplying capital directly.
