What Sighten does
Sighten is a privately held software company founded in 2012 and headquartered in San Francisco, California, that develops a software toolset to manage the complexity of distributed solar energy systems. With a team sized at 11-50 employees, the company builds software aimed at solar developers, installers, financiers, and asset managers who require infrastructure to streamline the design, deployment, and ongoing management of distributed solar portfolios. Sighten is led by co-founder Conlan O'Leary as CEO, alongside co-founder David Villagra as CTO and co-founder Graham Hommel.
The company raised approximately $5 million across four funding rounds between 2015 and 2017. The largest was a $3.5 million round in November 2015 led by Obvious Ventures, with participation from Alumni Ventures and Green D Ventures, following a $1.5 million round in June 2015 backed by Alumni Ventures and Endurance Companies. Subsequent strategic investments from Elemental Impact and WindSail Capital Group in early 2017 indicate alignment with mission-driven and energy-focused capital.

Revenue model
- Power Purchase Agreement (PPA): Customers pay for electricity generated by the solar panels rather than purchasing the equipment outright. EverBright owns the solar system and customers have predictable energy costs for up to 25 years with the option to add batteries. No upfront installation costs.
- Flex PPA: A flexible PPA option where customers pay only for the energy they use from the solar panels each month, rather than estimated or fixed amounts. Provides variable billing based on actual consumption.
- Shift PPA (California): California-specific PPA offering that includes solar panels and a non-backup battery, designed to capitalize on California's time-of-use rate structures.
- Solar Lease: Available in states where PPAs are unavailable. EverBright owns the solar system and handles installation financing. Customers make monthly payments based on the total cost of the system, not the system's solar production.

Sighten competitors and assessment
Company assessmentEmerging players
- Mosaic: Mosaic provides financing and a software-enabled platform for residential solar installers. Its installer-side tools and financing workflows overlap with the financier-tied portions of Sighten's toolset.
- PVsyst: PVsyst is a specialist PV system modeling and performance simulation tool widely used in solar engineering. While it is engineering-grade rather than sales-oriented, its modeling capabilities overlap with Sighten's design and performance software scope.
Broad incumbents
- Sunrun: Sunrun is the largest US residential solar installer and PPA/lease provider with its own operational and customer-facing software stack. As an in-house platform, it represents both a benchmark and a potential customer of best-in-class distributed-solar software like Sighten's.
- Enphase Energy: Enphase is a leading microinverter and battery manufacturer that also offers its Enlighten monitoring and installer software suite. Its installer platform competes for the same residential PV + storage workflow mindshare that Sighten targets.
Direct peers
- Aurora Solar: Aurora provides cloud-based solar design, sales, and proposal software for residential and commercial installers. It is the most direct functional competitor to Sighten's distributed-solar software toolset, covering PV design, shading, and proposal workflows for the same installer customer base.
- OpenSolar: OpenSolar offers free, end-to-end solar design, sales, and project management software for installers. Its freemium GTM and similar feature set compete head-to-head with Sighten's positioning for residential and small-commercial solar contractors.
- EnergySage: EnergySage operates a solar marketplace and quoting platform that connects installers with homeowners and supports solar proposal and comparison workflows. It overlaps with Sighten in installer-facing tools and the residential lead-to-design funnel.
- Solar.com: Solar.com runs an online platform connecting homeowners to vetted installers and provides installer-side software for quoting, design, and project management. It serves the same residential distributed-solar customer set as Sighten.
