Your Work. Our Tools. Real Results.

Not every project needs full discovery program support. Sometimes, you just need targeted support from a team that has proved that it knows how to tackle the difficult problems. Our Fee for Service model gives you focused access to X-Chem’s platform, people and technologies, scoped to your goals.

Choose the services you need. Set the timeline.
We’ll take it from there.

What you can access and what it helps you achieve:

DEL Screening

Fast track to hits, confident validation, and assessment of new libraries

Chemistry Support

Expand SAR, generate analogs or characterize priority compounds

Computational Modeling

Prioritize series, design next steps or explore new chemotypes

AI Tools

Use experimental DEL data and predictive models to guide design or highlight top candidates

Scientific Advisory

Clarify direction, interpret data, or de-risk early decisions

Build the Scope That Fits

Some projects need more than a single service but don’t require a full discovery program. That’s where our modular project model comes in.

We can work with your team to build a custom service program that combines elements of HitBuilder, LeadBuilder, or other key platform capabilities into a single, flexible scope. You set the objectives. We’ll shape the plan to meet them

This approach is ideal when:
  • You want flexibility, but still need defined milestones and deliverables
  • You are running multiple workstreams and need integrated support
  • Your internal team needs specific expertise to round out a broader effort
  • You aren’t ready for a full strategic collaboration but want to leverage a pioneering drug discovery partner

You get the flexibility of project-based work, without the fragmentation. Every engagement is strategically scoped, outcome-focused and fully supported by our team.

Why Teams Choose FFS

  • You want to accelerate a specific phase of discovery
  • You already have internal workflows and need expert support to fill the gaps
  • You’re evaluating a new target or modality and need help assessing viability
  • You prefer flexible engagement before moving into a full partnership
How It Works

Tell us what you need. We’ll define the scope, deliverables, and schedule based on your goals. Projects can be as small as a one-off compound synthesis or as involved as multi-round SAR modeling. You stay in control, and we stay accountable.
