If you’ve ever worked in process development, you know it’s not just about tinkering with equations or tweaking lab protocols in a vacuum. The best, most scalable, and cost-effective processes don’t materialize out of thin air—they’re built in close partnership with the suppliers who hold the components, materials, and expertise that make your end product work. For me, this hits home: I’m a process development supplier, not just a vendor dropping off parts at a loading dock, and for over a decade, I’ve seen teams skip out on supplier collaboration, only to hit costly roadblocks mid-launch. This post is a breakdown of the lessons we’ve learned from partnering with 120+ pharma, industrial, and specialty chemical process teams on integrating suppliers into their process development workflows—no corporate jargon, just real, battle-tested steps that actually move the needle. Process Development
Let’s start with the biggest mistake I see process development (PD) teams make: waiting to loop suppliers in until after they’ve already locked in a formula or pilot line setup. When a PD chemist or engineer finishes running 20 iterations of a reaction in the lab and calls to say, “Okay, we need 100 kg of this monomer next month,” that’s when the trouble starts. Maybe the material has a unique purity specification no supplier offers at scale. Maybe the lead time is three times what the team assumed because the supplier’s internal scheduling is buried under other orders. Or maybe, worse, the material has a latent stability issue that only comes to light when it’s produced in 1,000 L batches—something the lab-scale team would’ve caught months earlier if a process-focused supplier had been in the room.
Early collaboration isn’t a nice-to-have—it’s non-negotiable. For example, last year, a small biotech PD team we worked with was developing a monoclonal antibody purification process. Their lab team had optimized their resin binding conditions to run at pH 6.2, but the resin supplier, when we connected them early on, flagged that their standard resin couldn’t maintain consistent pore size at that pH for 1,000 L batches. Instead of the team scrapping six months of lab work to adjust their pH to a more scalable 7.0, the supplier tweaked the resin’s polymer cross-linking in two weeks to meet their exact need. That saved them an estimated $2.1M in rework and a 6-month delay to their clinical trial timeline. That’s the kind of win early supplier involvement delivers.
So, how do you actually make that early involvement work, beyond sending a generic “contact our sales team” email? It starts with aligning on the right level of supplier engagement at each stage of PD, not a one-size-fits-all approach. PD projects have four distinct phases, and the supplier’s role should shift with each—treating every supplier like a general contractor for a house build, not a one-off lumber provider.
First, the ideation and proof-of-concept phase (the first 0–6 months of most PD projects). This is where you need to bring in specialized suppliers, not just your go-to general material vendors. We call this phase “pre-competitive collaboration,” and the key here is to share enough detail to add value, but not so much that you risk intellectual property (IP)—a fear that stops a lot of teams cold. At our company, we use a simple IP framework with partners at this stage: PD teams share high-level process goals (e.g., “we need a coating that cures at 80°C with 95% transparency”) instead of full molecular structures, and we sign a basic non-disclosure agreement (NDA) that covers only the specific project parameters, not the team’s entire product line. We also bring in a cross-functional supplier liaison—not a sales rep who only cares about closing a big order, but a process specialist who’s actually run the kind of reaction or purification the team is testing. For that biotech team we worked with earlier, that specialist didn’t just talk resin specs; they explained how pH shifts affect resin performance at scale, a detail that never comes up in standard product data sheets.
A big part of this phase is also running small, informal “supplier screening sessions” to narrow down partners. Last quarter, a specialty chemical PD team was working on a new catalyst for green hydrogen production. Instead of sending RFPs to 10 suppliers blindly, we helped them host a two-day workshop where three potential catalyst suppliers brought lab-scale samples, ran 2-hour mini-reactions with the team, and walked through their scaling capabilities. By the end of the workshop, the team didn’t just know which supplier could deliver the right catalyst—they knew which one was willing to adjust the catalyst’s metal loading to cut production costs by 18% without sacrificing performance. That workshop cost the team less than $15,000 to host, but it avoided months of testing materials that couldn’t be scaled.
Once you move into the pilot scale phase (6–18 months in, where you’re moving from 1 L lab batches to 1,000 L or 10,000 L batches), your supplier’s role shifts from strategic partner to integrated team member. This is the point where lab-scale processes often break at scale, and suppliers hold most of the data that fixes those breaks. The biggest mistake here is treating suppliers like a vendor only responsible for delivering the material on time—instead, bring their engineers to your pilot runs. I’ve seen a pharmaceutical PD team run three unsuccessful pilot batches of a drug intermediate, blaming their own mixing process, until the supplier of the raw material pointed out that the batch’s particle size distribution was 12% wider than the lab sample, leading to inconsistent reaction rates. By adjusting the supplier’s milling process to narrow the particle size (a 2-hour fix) and adjusting the team’s mixing time by 10 minutes, they got the batch to yield 92%—up from the initial 61% failure rate. Without the supplier on-site during those pilot runs, that problem would’ve taken weeks to diagnose, costing the team critical time for their next regulatory submission.
During pilot scale, we also recommend setting up weekly 30-minute syncs with your key suppliers, not just monthly formal reviews. These syncs should be focused on three things: material performance data, scaling bottlenecks, and small, actionable adjustments—not long PowerPoint presentations. Last year, an industrial adhesives PD team we worked with had a pilot run where their adhesive’s cure time was 25 minutes, too slow for their manufacturing line. Instead of the team going back to the lab to tweak the formula, the supplier’s process engineer noticed that the carrier solvent used to transport the adhesive was evaporating too quickly in the pilot’s low-humidity environment, leading to uneven cross-linking. The supplier adjusted the solvent’s boiling point by 5°C, and the cure time dropped to 12 minutes—all in one week, no lab rework needed. That’s the value of having a supplier embedded in the pilot phase, not just sending material and a data sheet.
The third phase is validation and launch (18–24 months in, where you’re running full-scale production and preparing for regulatory or commercial launch). Here, supplier collaboration becomes about quality control and risk mitigation, not just performance. For regulated industries like pharma or medical devices, this means working with suppliers to align on validation protocols, material traceability, and change control processes. I worked with a medical device PD team last year that was preparing to launch a new implantable sensor. Their supplier of the biocompatible coating wanted to switch to a new raw material to cut costs, but the team was worried about regulatory approval. Instead of the supplier making the change unannounced, we helped them set up a joint change control committee that reviewed the new material’s data, ran small batches to test biocompatibility, and submitted the change to the FDA together. This cut the approval time for the switch from 6 months to 6 weeks, and the cost savings were passed directly to the team without any regulatory risk.
For non-regulated industries, this phase is about building a long-term supply chain that’s flexible enough to handle future scaling. Too many PD teams focus only on the launch, not on what happens when demand grows. A food and beverage process team we worked with was launching a new plant-based protein bar, and their supplier of the protein isolate had only committed to 50,000 kg/year of capacity for the first year. We worked with the supplier to build a modular scaling plan that allowed them to add 20,000 kg/year of capacity every quarter after launch, so when the product hit 120% of projected sales in month 8, there was no disruption in supply. That’s the difference between launching a product and sustaining it—suppliers aren’t just vendors for the initial process, they’re partners for its growth.
Now, you might be thinking: “What about IP risks? What if I share too much with a supplier and they steal my process or my formula?” That’s a valid concern, and it’s one we’ve addressed with the framework we use for every collaboration. First, only share the level of detail relevant to the phase. For ideation, share high-level goals, not full molecular structures or process trade secrets. For pilot runs, share specific batch data, but not your end-to-end product roadmap. Second, use tiered NDAs: a basic NDA for early-stage discussions, a more detailed agreement for pilot phase work that covers specific process parameters, and a formal supply agreement for launch that includes IP clauses specific to material modifications. Finally, vet suppliers thoroughly. We don’t work with suppliers who have a history of IP disputes, and we require all our partners to provide references from other PD teams. At the end of the day, the best suppliers for PD are the ones who want your process to succeed as much as you do, not just make a one-time sale.
Another key point: don’t limit supplier involvement just to material suppliers. Process development relies on equipment suppliers, analytical testing providers, and even logistics partners to get products to market. I’ve seen a semiconductor PD team that spent $2M on a new reactor, only to find out the logistics supplier they used couldn’t transport the reactor’s specialty gases without a custom approval that added 3 months to their timeline. If they’d looped their logistics partner in during the equipment planning phase, they could’ve adjusted the reactor’s gas delivery system to use a more transportable gas mix, avoiding that delay. PD is a cross-functional process, and every part of the supply chain plays a role.
If you’re looking to get started with supplier involvement in your PD process, here are three actionable steps you can take this week. First, schedule a 30-minute call with one of your key material suppliers before your next pilot run, and ask them to share one small scaling bottleneck they’ve seen with similar processes. You’ll be surprised how often those small questions lead to big solutions. Second, set up a simple internal process map that outlines which suppliers to involve at each PD phase, and what level of detail to share. No need for a 50-page document—one page that says “for ideation, involve material suppliers with process expertise; share only high-level goals” will work. Third, if you’re worried about IP, start with a low-risk project. Test early collaboration on a small, non-critical process tweak, and see how it works before rolling it out to your core projects.
Process Development At the end of the day, process development isn’t a solo act. The most innovative, scalable processes in the world aren’t built by in-house teams working in silos—they’re built in partnership with the suppliers who understand the materials, equipment, and logistics that turn a lab idea into a commercial product. I’ve spent 12 years as a process development supplier, and the biggest wins I’ve been part of didn’t come from selling the cheapest material or the fastest delivery. They came from working side-by-side with PD teams to solve problems no one could solve alone. If you’re looking to integrate suppliers into your process development workflow, we’re here to help—let’s set up a conversation to talk through your specific project challenges.
