THIIC was built by Summit Audience Segments to solve a specific problem: two parties need to identify shared audience records without either party sending raw PII across the wire.
Existing solutions required middleware vendors — companies that sit between sender and recipient, hold decrypted data, and charge for the privilege. That model creates a third-party dependency, a billing layer, and a PII custody risk that shouldn't exist in a bilateral exchange.
THIIC removes the intermediary. Sender hashes locally. Recipient matches locally. Nothing sensitive transits between them. The protocol is verifiable, the audit log is tamper-evident, and no vendor sees your data.
Summit Audience Segments is a pharma data platform with 15.3 million de-identified healthcare records, HCP intelligence across 16,600+ NPIs, and audience activation across DSP, clean room, and direct-to-publisher channels.
Summit operates three entities: the data platform (Summit Audience Segments), a patient health content hub (MySugarPill), and the THIIC protocol layer. THIIC is the transport and identity infrastructure that makes Summit's audience delivery HIPAA-safe by architecture, not just by policy.
Every Summit audience license ships with THIIC delivery at no additional cost. Partners receive encrypted tokens, not identifiable records. The exchange is bilateral. No middleware fees apply.
The exchange is bilateral by design. No third-party service sits between sender and recipient. No vendor receives, processes, or holds decrypted data at any step. Fees do not accrue per-record to an intermediary.
THIIC uses only NIST- and IETF-standardized primitives: SHA-256, HKDF-SHA256, AES-256-GCM, and Ed25519. No custom algorithms. No proprietary key schedules. Every primitive has published test vectors and independent review.
The protocol is novel in how it composes these primitives for a specific healthcare identity exchange problem — not in the primitives themselves. Architectural design choices are documented, auditable, and open to challenge.
20 years building patient acquisition infrastructure in healthcare media. Jake led sales at Alliance Health Networks during its rise as one of the largest healthcare-vertical ad networks online, then ran sales at Adprime Health, a category leader in pharma DTC media buying. He founded Silver Mountain Ventures in 2015 to operate at the intersection of healthcare consumer acquisition and direct-response strategy — work that produced the partnerships and operating relationships that became Summit's underlying data foundation. At Summit, Jake leads commercial strategy, partnerships, and the platform architecture that turns a decade of operationally-generated patient records into an addressable audience layer. He also owns Provocateur Gallery in Park City, where he lives with his three sons. Baylor University, B.A.
A two-time founder, two-time exited operator, and eight-time investor across seed and venture stages. Greg started his career as a G-10 spot currency trader at Barclays Capital and a credit derivatives broker at Creditex and Phoenix Partners Group during the post-2008 derivatives market reconstruction. He shifted to operating roles at Suja Juice, running supply chain through the company's growth from $700K to $80M+ in annual revenue. He later co-founded brekki (first-to-market ready-to-eat overnight oats, sold to Cedar's Mediterranean Foods in 2019) and Chefs Life (built from concept to nationwide Kroger launch in eight months). He continues to co-found and operate Jack Family Farms, an organic produce supply chain anchoring CPG brands including Suja. As founder of TGP Ventures, Greg has invested across consumer products, biomaterials, fitness, and financial technology — backing companies including Newlight Technologies, Betterment, Lume Cube, Zeno Gym, and Barry's. At Summit, Greg leads the company. He is responsible for capital strategy, board management, and the operating discipline required to build a data platform that compounds value over a 20-year exclusive license.

The operator behind the data. Jordan has spent 18+ years building and running healthcare patient acquisition businesses — first as Managing Member of Chase Consulting Services, then as VP of Marketing at Verus Healthcare (a top-tier national CPAP supplier, acquired by AdaptHealth in 2018), where he built the digital acquisition platform that enrolled 25,000+ sleep apnea patients in 18 months. Today he is Managing Partner & COO of Specialty Medical Equipment, one of the largest national mail-order providers of diabetic testing supplies, serving 50,000+ patients. He also founded GoHealth360 in 2016, the direct-response marketing engine specializing in diabetes and sleep health verticals that produced clients like PillPack and Divvy Dose Pharmacy. Both companies are operating entities whose decade of patient acquisition data Summit licenses exclusively. Jordan leads Summit's operations and is responsible for the data infrastructure connecting the source businesses to the licensed platform. He also co-founded Sleep8, a medical device manufacturer producing activated-oxygen sanitizing systems, where he holds two issued patents.
