- Ordinal
Led · Seed · Sep 2025
Ordinal is a gov-tech startup offering an AI research assistant that employs secure retrieval-augmented generation (RAG) to surface instant, source-grounded answers from municipal documents, codes, and records. By cutting the time employees spend on information retrieval—estimated at nearly 40 % of a typical work week—the platform aims to boost efficiency, improve decision-making, and strengthen public service delivery. The product has already been deployed in several municipalities, including Sallisaw (OK), Decatur (IN), Lowell (AR), Benton County (AR), La Quinta (CA), Pea Ridge (AR), and Willard (MO), demonstrating early traction and user adoption. Ordinal emphasizes compliance and accuracy by citing verified sources in every response, lowering barriers to adoption in a sector often slow to embrace new technology. The founding team—Jacob Herrington, Nick Spinazze, and Jacob Eubanks—plans to use new capital to expand its customer base, enhance a public-facing chatbot, and add features that further streamline civic operations. Although detailed revenue figures were not disclosed, the company reports a rapidly growing sales pipeline and measurable scaling progress facilitated by investor support. Long-term, Ordinal aims to restore civic trust and shape more efficient, transparent local governments through AI-driven knowledge management.

It closed a $20M Series B2 financing to support advancement of its pipeline and drug product manufacturing. Management says the funds will be used to advance clinical programs and scale drug product manufacturing. Detlev Biniszkiewicz, Ph.D. of MPM BioImpact will join Deka’s board as part of the raise. Deka Biosciences is an early-stage biotech developing novel cytokine therapies (Diakines™) to treat cancer and inflammatory diseases such as Crohn’s, psoriasis, rheumatoid arthritis and sepsis. Its Diakines™ are disease-specific therapeutic proteins designed to maximize patient benefit through improved pharmacokinetics/pharmacodynamics via targeted delivery of dual and complementary cytokines to affected tissues or cells. The company applies precision medicine to ensure treatment of patients most likely to benefit from and respond to cytokine therapies. Deka intends to use the newly raised funds to advance research, expand talent acquisition, and further develop its platform. Specifically, the company plans to file an Investigational New Drug (IND) application for its lead oncology program and advance the lead compound into Phase I clinical trials.
