For architects and engineers, the moment a building design leaves the drafting table and enters the construction site is often when the real work begins. It is a phase defined by a relentless flow of submittals, requests for information, and change orders, a process still largely managed through a chaotic mix of email, spreadsheets, and printed paper. This is the problem Part3, a Toronto-based startup, is trying to solve with a cloud platform designed specifically for the consultant team. The bet is that by digitizing and automating construction administration, they can reduce delays, mitigate risk, and give design professionals back something more valuable than time: control.
A wedge for the design side
The construction software market is dominated by giants like Procore, platforms built for the general contractor. Part3's founders argue that these tools, while powerful, are not purpose-built for the architect or engineer. Their platform carves out a specific wedge: the workflows that happen after the drawings are approved, when consultants must review, approve, and track thousands of items to ensure the built structure matches the design intent. The software centralizes submittals, RFIs, change orders, and site reports into a single digital workflow, aiming to replace manual tracking and fragmented communication [Part3, Unknown].
Key to their approach is integration, not replacement. Part3 offers a dedicated integration with Procore, allowing data to flow between the contractor's system and the consultant's platform [Part3 Help Center, 2026]. This positions Part3 as a complementary layer for the design side, a strategy that avoids a head-on fight with an entrenched incumbent while addressing a clear, underserved user base.
The team's forensic and field experience
The founding trio brings a rare blend of deep domain expertise and scaled software experience to a niche often overlooked by tech.
- Craig Gosselin, Co-founder & CEO. With over 20 years in architecture and construction administration, Gosselin's career at firms like IBI Group exposed him directly to the manual processes Part3 seeks to automate [OurCrowd, c. 2024-2025].
- Jad Saliba, Co-founder & CTO. Saliba is the former founder and CTO of Magnet Forensics, a digital forensics software company that went public on the Toronto Stock Exchange in 2021 before being acquired [TechCrunch, 2023] [Bloomberg Markets, 2026]. He brings proven SaaS product-building and scaling experience.
- Tim Meagher, Co-founder & CPO. A licensed architect with more than a decade leading construction administration on large institutional projects, Meagher provides the product vision grounded in daily user pain points [OurCrowd, c. 2024-2025].
This combination,operational grit from Gosselin and Meagher, plus technical and commercial pedigree from Saliba,forms a credible foundation for navigating both the complexities of construction and the challenges of building a venture-scale software business.
Funding and early traction
Public funding details are fragmented, but records indicate Part3 has raised a seed round to fuel its development. A 2022 seed round was led by Graphite Ventures [Part3, Unknown], with additional investment from firms like OurCrowd, 519 Growth Fund, and Chicago Ventures, alongside angels including Scott Wolfe and Kerry Liu [Crunchbase, Unknown]. The total disclosed funding across various sources is approximately $2.6 million.
The company has begun to demonstrate early product-market fit. One case study cites VCBO Architecture, which reported significant improvements in efficiency and productivity after implementing Part3 [Part3, Unknown]. The platform is offered on a per-user, subscription SaaS model, with a starting price listed at $125 per month [Software Advice, 2026].
| Funding Round | Amount (Estimated) | Lead Investor | Year |
|---|---|---|---|
| Seed | $2,000,000 | Graphite Ventures | 2022 [Part3, Unknown] |
| Seed | $625,000 | Undisclosed | 2022 [CB Insights, 2022] |
| Seed | $2,800,000 | Undisclosed | 2023 [Crunchbase, 2023] |
Note: Amounts are from separate public sources and may represent overlapping reporting.
The competitive landscape and integration strategy
Part3 operates in a competitive field, but its positioning is distinct. The primary alternative for most firms is not another startup, but the status quo of email and documents, or the awkward use of a contractor's platform. The company's most credible competitive risks come from two directions.
- Platform expansion. The largest risk is that a broad platform like Procore decides to build a deeply integrated, best-in-class module specifically for architects and engineers, effectively copying Part3's wedge from within its own ecosystem.
- Category confusion. For a small architecture firm, the decision to adopt a new, specialized tool requires clear ROI. Part3 must consistently prove that its focused platform delivers more value than adapting a generic project management tool or continuing with manual processes.
The company's answer to the first risk is its proactive integration strategy and deep user empathy. By building a superior experience for a user persona the giants have historically underserved, Part3 hopes to become the indispensable specialist tool, even within a broader tech stack.
The next twelve months
The immediate roadmap likely involves converting early validation into broader market adoption. Key milestones to watch include the announcement of additional named enterprise customers beyond the initial case study, potential expansion into adjacent consultant verticals like structural or MEP engineering, and the evolution of its AI-powered tools for task automation and field reporting [Part3, Unknown]. Given its seed-stage capital and team profile, a Series A round within the next 12-18 months would be a logical step to accelerate growth and solidify its position.
For the thousands of architecture and engineering firms managing construction projects, the standard of care today is a precarious one. Critical decisions about building materials and design changes are buried in inboxes, tracked on shared spreadsheets vulnerable to error, or lost in stacks of paper on a job-site trailer desk. This fragmentation isn't just inefficient, it introduces risk to project timelines, budgets, and ultimately, building safety. Part3's ambition is to bring the same level of rigor and visibility to construction administration that CAD software brought to design. The patient population, in this case, is every architect and engineer who has ever spent a weekend chasing down a missing submittal log, and the buildings whose quality depends on their vigilance.
