About Helonic

Built by builders to eliminate costly rework

Helonic is an AI company working to remove the $31B lost every year to construction rework. We are construction and software veterans who have lived the problem and are building the tool we wished we had.

Our mission

Catch every issue before it reaches the field

Construction is 13% of global GDP and one of the least digitized industries on the planet. Every year the US loses $31B to rework, most of it from mistakes that could have been caught during plan review.

We believe AI can fundamentally change this equation. Not by replacing experienced professionals, but by giving them superpowers: reviewing drawings faster, catching more issues, and focusing expertise where it matters most.

Our goal is to make AI-powered drawing analysis the standard in construction, as essential as Procore for project management or Bluebeam for PDF markup. Every project, every drawing set, every team should have access to this technology.

Our story

Helonic started from real frustration on real jobsites

Our founding team comes directly from construction. We have lived the pain of managing projects, coordinating trades, and dealing with the fallout when drawings did not match reality.

We watched millions of dollars burn on rework that could have been prevented with better plan review. The problem was not that people did not care. Manually reviewing hundreds of drawings across multiple disciplines, checking for coordination conflicts, code compliance, and missing information, is simply too much for any team to catch everything.

Important issues slip through. By the time they are discovered in the field, fixing them costs 10x more.

We combined our construction experience with deep computer science expertise to build what we wished we had: AI that reads drawings like an experienced project manager, catches the issues humans miss, and does it in minutes instead of days.

The team

Construction veterans meet builders of production AI

Helonic is small, focused, and built by people who have run the workflow and shipped the software.

Construction roots

  • Years of jobsite, preconstruction, and coordination experience.
  • Hands-on with RFIs, change orders, and the true cost of rework.
  • Worked across multifamily, commercial, healthcare, and institutional projects.

Software and AI

  • Engineering experience at leading technology companies.
  • Deep expertise in machine learning, computer vision, and document analysis.
  • Shipped production AI systems processing millions of construction documents.
Why we are different

Construction AI that fits the way your team actually works

Built by builders

We have lived the pain of rework and RFIs. We are not outsiders guessing what construction needs. We have been in the field and the trailer.

Works with 2D PDFs

Unlike BIM clash detection that requires 3D models, Helonic reads the drawings you already have. No model, no problem.

Fits your workflow

Native Procore and Autodesk integration. Pull drawings in one click and push issues back as RFIs with another. Helonic plugs into how you already work.

Y Combinator

Proud to be a Y Combinator company

Helonic is part of Y Combinator, the accelerator behind Airbnb, Stripe, DoorDash, Coinbase, and more than 4,000 other companies with a combined valuation north of $600B.

Being a YC company means we are held to a high bar on execution, product quality, and customer focus. We are building a company designed to change how construction approaches plan review and coordination.

About Helonic FAQ

Who founded Helonic?
Helonic was co-founded by Milind Sagaram (CEO) and Manas Gandhi (CTO). Milind leads product and go-to-market and works closely with general contractors, project managers, estimators, and owners, while Manas leads engineering and AI research and works directly with structural, MEP, civil, and fire protection engineers. The founding team combines hands-on construction delivery experience with production machine learning and computer vision expertise.
Is Helonic backed by Y Combinator?
Yes. Helonic is a Y Combinator company, the accelerator behind Airbnb, Stripe, DoorDash, and more than 4,000 other startups. The legal entity is Articulate AI, Inc., and the product is branded Helonic.
What does Helonic actually do?
Helonic is an AI platform that reviews construction drawings and flags coordination conflicts, code compliance issues, missing information, and constructability problems before they reach the field. It reads the 2D PDF drawing sets teams already have, so it does not require a 3D BIM model to run.
How is Helonic different from BIM clash detection tools like Navisworks or Solibri?
BIM clash detection requires a coordinated 3D model, which many projects never build or build too late to prevent RFIs. Helonic works directly on the 2D PDF drawing set, so it catches issues during plan review even when no model exists. It complements BIM workflows rather than replacing them.
Does Helonic replace professional plan review?
No. Helonic is built to support licensed professionals, not replace them. It surfaces likely issues with page references, severity, and recommended actions so reviewers can verify and act quickly, keeping the engineer or project manager in control of every decision.
Who does Helonic build for?
Helonic serves teams across the project lifecycle, including general contractors, architects, MEP and structural engineers, estimators, owners and developers, plan reviewers, and construction managers. Role-specific workflows are documented on the Solutions pages.

Milind Sagaram

Co-founder & CEO, Helonic

Milind is the co-founder and CEO of Helonic, where he leads product and go-to-market for AI-powered construction drawing analysis. He works closely with general contractors, project managers, estimators, and owners to understand how drawing quality drives project outcomes - and where AI can reduce RFIs, change orders, and rework. Milind has interviewed hundreds of construction professionals across project delivery roles, from preconstruction estimators at ENR top-400 contractors to facilities directors at institutional owners, and uses those conversations to shape both product direction and the way Helonic talks about the work.

Areas of focus
  • Construction project delivery and preconstruction
  • RFI and change order economics
  • Owner and GC workflows for drawing QA/QC
  • Estimating risk and bid-stage scope assessment

How this page was researched: Company facts on this page were confirmed against Helonic's Y Combinator company profile and the legal entity registration for Articulate AI, Inc. Industry figures are cited from the Construction Industry Institute (annual U.S. rework), the Navigant Construction Forum RFI cost study, and McKinsey's construction productivity research. FAQ topics focus on the questions prospective customers, partners, and press most often ask about who builds Helonic and how it fits alongside BIM and manual review.

Manas Gandhi

Co-founder & CTO, Helonic

Manas is the co-founder and CTO of Helonic, where he leads engineering and AI research for construction drawing analysis. He works directly with structural, MEP, civil, and fire protection engineers to translate the way they review drawings into AI systems that flag the issues that actually matter in the field. Before Helonic, he built machine learning pipelines for technical document understanding and has spent the last several years interviewing licensed design engineers and discipline leads to ground product decisions in real practice rather than industry assumptions.

Areas of focus
  • AI for technical document understanding
  • Cross-discipline coordination workflows
  • Code compliance automation (IBC, NEC, NFPA, IPC, IMC, ASCE)
  • Structural and MEP drawing review systems
