Serving biopharma since

2009

Built for biopharma, and only biopharma

Orbytel Group has worked exclusively with biotechnology and pharmaceutical companies since 2009. Our data is shaped by how those teams plan, review and present their work.

Quality over quantity.

Organized by therapeutic area

Every conference is classified into the therapeutic areas biopharma teams plan around, so you can pull everything for oncology or rheumatology without building your own mapping.

Clinical and medical focus

We cover clinically and medically oriented meetings and journals. We leave basic research and laboratory instrumentation to others.

Curated to remove the noise

Predatory conferences and journals are kept out, and coverage centers on the meetings and publications that matter to medical and scientific teams. Less noise means less cleanup on your side.

Reviewed by people who know the field

Our team checks records against official sources, and every date shows whether it is confirmed or still an estimate.

Standardized and presentation ready

Every record follows the same format, so the data is easy to review and can go straight into a slide, a plan or a report. Conference names, for example, always follow one pattern:

Data catalog

One API, a growing set of connected datasets

Every dataset uses the same key, the same request style and the same change feed. Records link to each other by ID, so a new dataset fits into what you have already built.

How syncing works

Conferences: date confidence

Every date tells you how sure we are

Next year's deadlines are often unannounced when you need to plan. Rather than leave a gap or pass off a guess as fact, each date carries its own status.

ConfirmedPublished by the organizer and checked against the official source.

EstimatedProjected from the lead times of the meeting's earlier editions, until the organizer announces it.

CopiedCarried forward from the previous edition and waiting for confirmation.

How syncing works

Stay in sync without reloading everything

Every dataset works the same way. Download it once; after that, each request returns only what was added, changed or removed since the last one.

Load the full dataset once
Download every record you are licensed for as one compressed file from /v1/exports/{dataset}. It includes a sync token.
Ask for what changed
Call /v1/{dataset}/changes?since=<token> daily, hourly, or as often as you like. Or filter by date with updated_since.
Apply updates and removals
Changed records arrive in full. Removed ones arrive as "deleted": true, so your copy never keeps a stale entry. Save the new token for next time.

Questions

Frequently asked questions

Do I need a developer to use the API?

No. The Excel starter workbook connects to the API for you: paste in your key, choose your filters and click Refresh All. Developers can use the same data through the API directly.

How current is the data?

Our team and monitoring tools check organizer websites and announcements throughout the year. A change is available through the API as soon as it is saved, so a daily sync keeps you within a day of our database.

Why isn't every conference or journal included?

On purpose. We cover the clinical and medical meetings and journals that matter to biopharma teams, and we leave out predatory and low-relevance ones, so you spend less time filtering noise.

Which datasets are coming next?

Conference abstracts are next, followed by professional societies and then key opinion leaders. Each new dataset uses the same key, request style and change feed as the ones available today.

What happens when a record is removed or merged?

The change feed returns it with "deleted": true, so you can remove it from your copy. You never need to reload the full set to find removals.

Which formats do you provide?

The API returns JSON. Full exports are compressed JSON Lines files, one record per line, which load easily into databases. Excel and Power BI users get a flat table through the starter workbook.

Do you include past editions?

Yes. Conference records start with the 2023 editions, and each meeting's editions are linked so you can compare deadlines and lead times across years.
