Opportunity
JustFill is a carbon accounting workflow SaaS for decentralized clinical trials. It guides coordinators through a simple form to report emissions, automatically pulling data from calendars (travel), supplier networks (equipment), and geospatial analytics (site energy). AI policy search ensures the report aligns with the latest standards, turning a painful consultancy invoice into a few clicks.
Prefer to build this yourself?
A solo developer Micro-SaaS concept also exists for this domain — scoped for one person to build and grow to $5k MRR.

Research competitors and sharpen the wedge
Open this proposal in another AI with a research prompt: it will find competitors with real traction and recurring complaints, then help you improve the idea with a sharper wedge and MVP focused on fixing what incumbents get wrong.
Build this idea with Claude Code or Codex. Both links open with a coding-agent prompt for the first MVP.

Start with the buyer and the pain. The rest of the idea only matters if this audience has a reason to pay now.
Who Pays
Coordinators of community-run clinical trials, small-to-mid-size research organizations, and academic medical centers conducting decentralized or site-based studies.
Painful Problem
Community-run clinical trial coordinators face increasing pressure to report and reduce the carbon footprint of their trials, but existing solutions are either too complex (requiring sustainability experts) or too generic (ignoring clinical trial specifics). They waste weeks on manual data collection and risk non-compliance with emerging environmental regulations.
Then test whether the product is a credible answer to that pain, and whether this domain gives the idea a memorable strategic shape.
What It Does
Integration of calendar APIs to auto-capture travel distances and modes; a supplier network API to retrieve product carbon footprints (e.g., lab kits, devices); geospatial analytics to estimate site-specific energy emissions; and an AI policy search engine that cross-references the completed form against current regulatory frameworks (e.g., NIH Climate Action, EMA environmental guidance).
How It Creates Value
Reduces carbon reporting effort from weeks of manual work and expensive consultants to under two hours per trial, with built-in compliance assurance and auditable data trails.
Proof In The Product
- One-click calendar import: automatically fills travel emissions from coordinators' and participants' calendar events, suggesting mode of transport (car, flight, rail) and CO2 estimates.
- Policy alert: an AI agent scans the completed form and flags any fields where the trial's carbon intensity exceeds local regulatory thresholds, with one-click fix suggestions.
- Carbon Story dashboard: a visual timeline of emissions across trial phases (setup, enrollment, monitoring, closeout) with anonymized benchmarks against similar trials in the platform.
A fundable idea also needs a path to revenue, distribution, and defensibility.
Economic Engine
Per-trial subscription fee scaled by trial duration and number of sites; premium tier adds automated data export for funder reports and consulting-grade audit logs.
Why It Wins
Purpose-built for clinical research – not a generic calculator. Pre-populates from trial management tools (calendars, procurement), speaks the language of protocols and CRFs, and adapts to regional policy changes via AI.
Finally, the diligence layer shows what still needs to be proven before this becomes more than a promising concept.
Pros
- Addresses a rapidly growing regulatory and funding requirement for sustainability in clinical research.
- Automates data collection from existing calendars and supplier records, minimizing manual input.
- AI policy search ensures reports stay compliant without coordinator needing to track changing rules.
- Simple 'just fill' UX requires no training, lowering adoption barriers for non-technical coordinators.
- Can serve as a gateway to other trial compliance services (e.g., site monitoring, ethics reporting).
Cons
- Initial supplier network coverage may be sparse, requiring early manual entry for some items.
- Geospatial emission estimates for energy use rely on average data, which may not capture site-specific variations.
- Requires trial coordinators to actively connect calendars and authorize data access, a possible friction point.
- Per-trial subscription fee may feel like an extra cost if carbon reporting is not yet mandatory for the coordinator's funder.
