Insight Partners led Gridsight’s USD $26 million Series B (~A$36.3M), reported September 1, 2026 by Capital Brief from the company’s media release. Galvanize joined; returning investors include Airtree, Energy Transition Ventures, and Aera VC.
Spine: the scarce asset is not “more AI” — it is usable capacity on the wires utilities already own, while interconnection queues for data centers, EVs, and DERs explode.
Key facts
| Field | Detail |
|---|---|
| Company | Gridsight (Australia-founded; utility capacity software) |
| Round | USD $26M Series B (~A$36.3M) |
| Date | September 1, 2026 (Capital Brief) |
| Lead | Insight Partners |
| Participants | Galvanize; Airtree; Energy Transition Ventures; Aera VC |
| Named customers | Xcel Energy; United Illuminating (Avangrid); Endeavour Energy (AU) |
| Company claim | Up to ~75% of grid capacity unused on average (varies by location/time) |
Who uses the product — and for what job
Users: distribution utilities and DSOs planning/orchestration teams.
Job: quantify where and when spare capacity exists so they can connect customers faster and aim CapEx at grid pockets with highest impact — CEO Brendan Banfield’s framing in the release.
This is operations software for regulated buyers, not a consumer energy app.
Why now
- Data-center and electrification load is outrunning greenfield infrastructure timelines.
- Interconnection delays are now a board-level constraint on economic growth.
- Utilities need decision systems for dynamic, geographically uneven capacity — not static planning spreadsheets.
Why Insight — portfolio fit
Insight is a classic ScaleUp software buyer: named enterprise logos, multi-geo expansion (AU → U.S. utilities), and a path to category software in a regulated vertical.
Likely founder rationale: graduate from Australian climate/energy VCs (Airtree et al.) to a global software growth lead that can underwrite U.S. utility sales cycles.
| Dimension | Fit |
|---|---|
| Stage | Series B expansion |
| Thesis | Vertical SaaS for grid operators |
| Buyer | IOUs / DSOs |
| Risk | Sales-cycle length; model accuracy vs field outcomes |
Airtree, Galvanize, ETV, and Aera are covered editorially without inventing /fund/ pages.
Competitive map
| Player | Difference |
|---|---|
| Traditional planning / ADMS suites | Strong on SCADA; weaker on AI capacity discovery |
| Emerald AI / flexible-load platforms | Different layer (flexibility markets vs capacity quantification) |
| CivilGrid | Underground asset intelligence — complementary dig vs capacity story |
What is not proven
- Revenue, ARR, and NRR are not disclosed.
- The “three-quarters unused” figure is a company claim — diligence should ask methodology by feeder class.
- Valuation not reported.
Practical takeaway
- Founders (climate SaaS): Name utility logos before pitching Insight-scale checks.
- Investors: Underwrite interconnection time saved and model validation — not TAM slides about “energy AI.”
- Operators: Relevant if your interconnection queue is the bottleneck, not generation scarcity alone.
