StructionSite: from MVP to acquisition in construction tech.
General contractors needed a way to document job sites without manual photo logs. StructionSite built AI-assisted reality capture that turned 360-degree site walks into searchable, timestamped visual records. MVP to acquisition.
Originally at structionsite.com (now redirects to dronedeploy.com post-acquisition). Manuel Zamora built the MVP architecture.
The problem
Construction sites change daily. Walls go up, systems get installed, inspections happen. But documenting that progress is manual, inconsistent, and usually done with a phone camera and a folder of timestamped photos that nobody can search later.
When a dispute arises (was that pipe installed before or after the drywall went up?), the answer is buried in thousands of unsorted photos. General contractors, project managers, and owners need a visual record they can trust, search, and reference months or years later.
The existing solutions were either enterprise-heavy (Procore, PlanGrid) and didn't focus on visual documentation, or they were simple photo tools that didn't organize content by location and time. The gap was an automated, AI-assisted capture system that made site documentation as easy as walking the job.
What was built
A reality capture platform for construction. Walk the site with a 360-degree camera, and the system organizes, timestamps, and makes every frame searchable.
360-Degree Site Capture
Walk the job site with a 360 camera. The system automatically captures, timestamps, and geo-tags every frame as you move through the space.
AI-Assisted Documentation
Computer vision identifies and tags construction elements. Progress tracking against plans without manual annotation.
Timeline Navigation
Scrub through the visual history of any location on the site. See exactly what was there on any given date. Dispute resolution in seconds.
Floor Plan Integration
Captured imagery mapped to floor plans. Click any room on the plan to see the visual record at that location across time.
Searchable Visual Records
Every capture is indexed and searchable. Find specific areas, dates, or construction phases without scrolling through thousands of photos.
Team Collaboration
Project managers, GCs, owners, and subs all access the same visual record. Shared truth, no conflicting photo folders.
The engineering challenge
The MVP had to prove three things in 2.5 months: that 360-degree capture could be automated, that imagery could be organized by location and time without manual tagging, and that the result was useful enough for GCs to pay for.
Technical requirements
- 360-degree image capture and stitching
- Geo-location mapping to floor plans
- Temporal indexing (same location over time)
- Large media storage and retrieval
- Mobile capture + web viewing
Scale constraints
- Hundreds of 360 images per site walk
- Multiple walks per week per project
- GC teams across dozens of active projects
- Years of historical imagery per site
- Field conditions (dust, connectivity, speed)
Manuel's role
Manuel Zamora built the MVP architecture for StructionSite. This was a prior-career role before founding Downshift. The MVP shipped in 2.5 months and was accepted into the 500 Startups accelerator program.
The experience of taking a construction-tech product from zero to a working MVP under extreme time pressure (accelerator deadlines) is directly reflected in Downshift's 4-6 week build timeline. When a founder says "can you really ship a production product in 6 weeks?", the answer comes from having done it under tighter constraints.
Specific role details and dates are available on Manuel's LinkedIn.
Outcomes
Public metrics from Crunchbase, press coverage, and the DroneDeploy acquisition. No internal or non-public numbers.
From zero to working MVP. Built under accelerator timeline pressure.
Total venture funding raised across multiple rounds.
Annual recurring revenue reached before acquisition.
By DroneDeploy, a leader in drone-based reality capture used on 3M+ sites in 180 countries.

Working on something at this scope?
The MVP-to-acquisition path starts with production-grade engineering from day one. Downshift brings the same intensity to every venture it builds.
