Why Peer Receipts exists

From scattered experience to shared context.

From quick conversations to detailed notes, scientists generate practical knowledge every day. Peer Receipts gives that experience a place where others can find and learn from it.

About Peer Receipts

The problem is not lack of information. It is lack of usable experience.

Scientific information is abundant. What scientists often lack is the practical context that turns scattered information into usable insight.

The information landscape

Scientific information is everywhere.

There is no shortage of product information, publications, protocols, and vendor materials.

  • SpecificationsTell you what a product is designed to do.
  • PublicationsShow what was demonstrated under defined experimental conditions.
  • VendorsExplain what a product offers.

The missing piece

Practical experience is harder to find.

Peer experiences show how tools perform, fit, and work together in practice.

  • What was it actually like to use?
  • Where did it perform well?
  • Where did it fall short?
  • What did it work well with?
  • What did the workflow depend on?
  • What would you change next time?

Why stacks

Scientific decisions rarely happen one product at a time.

Tools, reagents, software, and services rarely work in isolation. Their value depends on how they fit together within a real workflow.

Individual Receiptspreserve product-level experience.

Receipt Stackspreserve the relationships between those experiences.

Flow Cytometry Workflow

“This combination works seamlessly for our immune cell profiling. The instrument and reagent kit are well-matched, and the software makes analysis straightforward. Together they have significantly reduced turnaround time.”

  • Immune cell profiling
  • Research use

Stacks show how scientific tools work together.

  • Reflect real-world workflows and dependencies
  • Highlight what actually works well together
  • Surface trade-offs and constraints
  • Help scientists make more informed decisions

The context behind the score

The same product can be the right fit in one context and the wrong fit in another.

An ELISA kit used for exploratory biomarker screening may be evaluated differently from one used in a regulated QC environment. A kit that works well for small-batch research may be too variable or too slow for a high-throughput standardized workflow.

That is why Peer Receipts connects opinions to the circumstances behind them — use case, environment, duration, workflow, contributor background, trade-offs, and outcomes.

Our trust model

Anonymous sharing. Verified contributors.

Scientists should be able to speak candidly while still knowing contributions come from verified members of the scientific community. Peer Receipts separates professional verification from public identity.

Professional background is verified

  • Scientific organization and industry
  • Role and focus in the scientific community

The long-term vision

Building the memory layer for scientific practice.

Today, practical scientific knowledge is fragmented across people, labs, and workflows.

Our vision is to connect those experiences — products, conditions, workflows, outcomes, and trade-offs — into a shared layer of scientific context.

As that knowledge grows, Peer Receipts can reveal what works, where it works, what it works with, and what others learned along the way.

From isolated experience to a living map of scientific practice.

About us

Built by scientists, for scientists.

We know the small things scientists do for each other every day — asking a colleague what they used, warning someone that a product was more trouble than expected, sharing the workaround that finally made something work.

A lot of the most useful knowledge in science lives in those conversations.

Those lessons matter.

They come from trying things, troubleshooting, comparing notes, and figuring out what actually works in practice.

We built Peer Receipts to help those lessons travel a little further — beyond one conversation, one team, or one lab.

Because knowing what someone used is only part of the story. What really helps is understanding the context around it: what they were trying to do, what they used it with, where it worked, where it didn’t, and what they would do differently next time.

Peer Receipts gives those lessons somewhere to live, connect, and become useful to the next scientist.
