Our Story

Built by people who lived
the billing week.

Before Gridline was a company, it was a frustration. The manual processes. The utility formats that change without warning. The billing weeks that ate entire teams.

We built Gridline because we lived the problem first.

What we've built into the model

Years of operational knowledge, not just document parsing

Bill structures we handle

  • Net metering statements
  • Community solar credit statements
  • Virtual net metering allocations
  • Consolidated utility bills
  • Time-of-use rate applications

Edge cases we've catalogued

  • Mid-cycle rate changes
  • Retroactive credit adjustments
  • Subscriber moves and transfers
  • Partial-month allocations
  • Multi-meter subscribers
  • Low-income program variations

What you don't have to do

  • Copy-paste from utility PDFs
  • Maintain spreadsheet formulas
  • Manually create each invoice
  • Hope you caught all the errors
  • Spend days reconciling credits

Our journey

From frustration to automation

2018

Gridline founded

Started from firsthand experience with community solar billing pain.

2019

First billing automation

Deployed initial system. Started cataloguing utility formats.

2020

Scaled to multiple programs

MA SMART, MN Community Solar Garden, and more.

2021

Model development begins

Started training domain-specific extraction models.

2022

Platform milestone

90%+ straight-through rate achieved.

2024

Full platform launch

Billing cycles in minutes, not days. Full audit trail.

2025

Today

20+ projects across multiple state programs.

Why automation works now

Operators have been doing manual billing for years. What changed?

AI got good enough

Modern AI can actually extract structured data from messy utility bills—if you know how to validate and constrain it.

We have the edge cases catalogued

Years of operational data means we've seen the variations that break naive automation.

The cost of errors is too high

As portfolios grow, manual billing doesn't scale. A 2% error rate on 10,000 subscribers is 200 problems per cycle.

How we build

Principles that guide every line of code

Operator-First

We build for the person who runs billing every month. Their workflow is our spec.

Traceable by Default

Every step logged. Every artifact versioned. Every decision auditable.

Automation with Control

Automate the repetitive. Flag the exceptions. Keep humans in the loop.

Ship Fast, Iterate

Real software solving real problems. No vaporware. No roadmap theater.

Who's building this

Mike

Founder

Building Gridline to solve the operational pain points that slow down clean energy deployment. Previously worked on energy project finance, grid resilience modeling, and document automation.

"

The biggest impact we could have wasn't in education or research — it was in solving the operational pain points that slow down clean energy deployment.

— On why we pivoted from education to product

If you're an operator spending days on billing every month, I'd love to hear about your workflow.
