MITO Spent a Decade Making Graphene Boring Enough for the Factory Floor

The most useful thing MITO Material Solutions did with graphene was make it less exciting. For years, graphene lived a double life: miraculous in a slide deck, temperamental in a mixing vessel. It is strong and light, but nanoparticles have a habit of clustering together. A clump is not an enhancement. It is a tiny black troublemaker hiding in expensive resin.

MITO's answer was E-GO, a hybrid additive that attaches graphene oxide to an epoxide form of POSS, a cage-like silicon molecule. The chemistry is meant to help the particles disperse and bond with the surrounding polymer. In the recipes MITO promotes, the suggested dose can be roughly 0.1 percent of polymer weight. Manufacturers can add it as powder, a liquid dispersion or a spray, depending on how they already make a part.

That last phrase is the business. MITO did not sell manufacturers a dramatic new production line. It sold the possibility of using the same resin, tooling and process while changing what the finished material could tolerate. Its customers were formulators and makers of composite parts: skis, fishing rods, vehicle panels, coatings, infrastructure components and, potentially, aerospace hardware. It earned money by selling specialty additives and formulated systems, then helping customers test the right mixture.

The company hiding in a class assignment

MITO started at Oklahoma State University with an entrepreneurship course and technology that was still waiting for a commercial home. Haley Marie Keith, then an MBA student, met materials-science professor Ranji Vaidyanathan's patent-pending work through the class. Kevin Keith, her husband and an engineer, joined the effort. They interviewed people across the composites industry, won business-plan money and grants, licensed the university technology, and founded MITO in 2016.

The interviews changed the target. Plenty of companies were working on stronger fibers. Far fewer were improving the matrix - the epoxy or polymer that surrounds the fiber and transfers loads through the part. In plain English, everyone admired the skeleton while the glue was quietly deciding when the thing would split. MITO chose the glue.

“No one expected it to become a company.”Haley Marie Keith, on MITO's classroom origin

The founders went full-time after graduating in late 2017 and moved into their first lab in early 2018. National Science Foundation and Oklahoma support supplied more than $1.1 million for R&D. The Heritage Group's hard-tech accelerator brought them to Indiana in 2019, closer to chemical companies, manufacturers and Midwestern capital. A $1 million seed round followed in 2020, then a $4.6 million extension in early 2022 that included specialty-chemicals company Ingevity.

What failed first: the easy version

Graphene's theoretical properties were not the sticking point. Integration was. Bare graphene or graphene oxide can agglomerate, settle, change viscosity or produce inconsistent results from one batch to the next. Manufacturers also dislike additives that demand unfamiliar safety procedures, new equipment or a rewritten production schedule. A material can win every laboratory comparison and still lose to Tuesday's shift change.

MITO's functionalization platform was designed around those objections. E-GO's chemical and physical bonding points help it remain distributed through the polymer instead of behaving like chocolate chips sinking in pancake batter, an analogy Kevin Keith once used. The particles are micron-sized for handling. The product is fiber-agnostic, and MITO says it can enter processes including injection molding, pultrusion, resin-transfer molding, prepreg and additive manufacturing.

This is also where the claims need discipline. MITO advertises improvements as high as 135 percent, but no additive produces a universal result. Performance depends on the resin, fiber, filler package, dispersion equipment, cure cycle and property being measured. MITO has acknowledged that complex resin chemistry and heavy existing filler loads can be more sensitive. Its useful promise is not “every polymer becomes 135 percent better.” It is “we can run the experiment without first remodeling your plant.”

Ten grams, two skis and one honest test

The first public commercial application was not an airplane. It was a custom ski. During the 2020 outdoor boom, Colorado's Folsom Custom Skis made two nearly identical pairs. One build received ten grams of MITO's functionalized graphene oxide blend in the epoxy. On the bench, the enhanced pair showed no significant difference in stiffness, weight or measured flex. That was the first useful failure: the easy tests did not create a fireworks display.

So Folsom put the skis on snow. Its tester reported a more energetic, responsive ride, and the company moved the additive into selected touring constructions. Buyers could add it for $50. That price is the closest public answer to “what did it cost?” at the finished-product level. MITO did not publish a general industrial price list; specialty-material sales depend on volume, formulation and support.

The skis changed the conversation because customers could touch them. A visible product made the nanotechnology legible. Parlor Skis later used E-GO, and St. Croix applied MITO functionalized graphene in its premium Evo and Evo Salt fly rods, tuning strength, recovery, torsional stiffness and sensitivity while controlling the material in-house. Sporting goods became a beachhead, not the market ceiling.

The lab result opened the door. The ski run made the result believable.

A portfolio, not a packet of black powder

E-GO remained the flagship, offered for direct mixing, spray application and in the ready-made Res-1 laminating epoxy. ACRE moved the same functionalization idea into cornstarch, aiming to replace mined fillers such as mica and help recycled or bio-based polymers retain useful performance. LIGRA went into Fenix Fiber+, a collaboration with recycled-carbon-fiber company Vartega. Later public deal documents also named OMEGA and DELTA across thermosets, thermoplastics, coatings, liquids and resins.

The Vartega work shows how MITO tried to turn sustainability into measured material behavior. In the disclosed formulation, the partnership reported a 9 percent lift in tensile strength, 50 percent in elongation, 18 percent in flexural strength, 16 percent in notched impact and 37 percent in unnotched impact. Those are test-specific results, not laws of nature, but they show the commercial idea: use recycled fiber, then recover performance with chemistry that does not jam the customer's process.

MITO's competitors were not merely other graphene suppliers. They included conventional tougheners, carbon nanotubes, alternative fillers, a customer's internal chemistry team and the most dangerous incumbent of all: leave the recipe alone. MITO differentiated itself with functionalization, low loading, several delivery formats and application engineering. In 2022, the Graphene Council awarded E-GO its first Verified Functionalized Graphene status after safety and technical audits, third-party testing, a lab visit and review of toll manufacturer Monument Chemical. The process verified capacity of three to five metric tons a year.

The exit, with an earnout attached

By June 2026, Australian producer First Graphene saw something it could buy: U.S. market access, functionalization IP, equipment, product lines, supply and client agreements, immediate revenue and more than 25 clients in late-stage testing. It signed a binding asset-purchase agreement with MITO for AU$850,000 in total potential consideration.

The structure is worth reading closely. Most of the consideration was contingent on revenue generated by the MITO business after closing. That does not erase the company's technical progress; it prices the remaining commercial risk. Deep-tech pilots can look like a pipeline for a long time. The buyer paid cash for a working platform and kept the larger payout tied to sales. First Graphene later said the acquisition had completed and put Haley Keith in charge of U.S. business development.

MITO's decade therefore ends less like a victory lap than a relay handoff. The founders carried university IP through grants, scale-up, certifications and early products. First Graphene brings a broader graphene portfolio and public-company distribution. Whether the combination works will depend on the same thing that always mattered: converting recipes and tests into repeat orders.

What can be copied - and what cannot

Founders can copy the sequence: license overlooked IP, interview process owners, identify the adoption bottleneck, design around existing workflows, win a public and testable beachhead, and add independent validation before chasing regulated markets. They cannot copy the timeline away. Materials qualification is slow because failure is physical, warranties are expensive and a formula that works in one resin may disappoint in another.

MITO fits in the specialty-chemicals layer between graphene producers and finished-goods manufacturers. It did not need consumers to know its name. It needed the formulator, process engineer and purchasing manager to agree that a tiny addition could produce a repeatable improvement. The company's sharpest insight was that advanced materials become valuable only after they become routine. Graphene supplied the wonder. MITO worked on the instructions.
