Triangle Startups

Standout of the week

SelSym Biotech

Preclinical biotech developing synthetic platelet-mimetic therapeutics to stop bleeding at the point of injury.

Took its first equity financing from Persephoni Bio and will operate from Persephoni's RTP studio.

Persephoni Bio disclosed SelSym's first equity financing on July 15, naming itself lead investor and strategic partner and saying SelSym will run out of Persephoni's Clinical Impact Studio in Research Triangle Park. SelSym's lead candidate, SymClot, is a blood-type-agnostic synthetic platelet designed to control hemorrhage at the point of injury; the science originated in Ashley Brown's Advanced Wound Healing Lab at NC State. The financing amount and stage were not disclosed. The release calls the company Raleigh-based while its own site lists a Durham contact address, so the headquarters city is unresolved pending first-party confirmation.

Trybl

Duke and UNC grads shipped Coffee Chat, a social-automation app, on iOS.

Trybl is a bootstrapped 2025 startup building social-automation tools that match users for coffee chats and handle scheduling, AI prep, and follow-up. GrepBeat reported on July 16 that an early Communities release at Duke reached 200 users before the team rebuilt the product around Coffee Chat, now live on iOS. The founding team, Hakeem Shitta-Bey, Christopher Williams, and Nati Worku, won $2,500 at the NCCU AI Hackathon and $1,000 at an Alpha Phi Alpha regional pitch competition.

Deep dives

Capital

3 rounds

One disclosed number and two financings without one. 410 Medical's $12M growth round is the week's headline figure; SelSym's first institutional money and Extellis adding Shell Ventures both came without company-level amounts.

Extellis extended its November seed round with a new investment from Shell Ventures; the Durham satellite-imaging company did not disclose the amount and said the capital supports its Pathfinder mission, team expansion, and progress toward commercial operations

The student-founder pipeline supplied good news, with Launch Chapel Hill capping its first international accelerator. The incentive ledger supplied the other kind.

Institutional

North Carolina cancels Kempower's 306-job Durham incentive agreement at the company's request

Kempower had committed to 306 Durham jobs and reported just over 100 employees at the end of June after pausing hiring; none of the roughly $3 million in potential state incentives was paid because benchmarks were not met. The company says the Durham facility stays open and attributes the pullback to weaker demand after expired federal EV incentives and delayed customer projects. Kempower is Finland-headquartered, so this is an employer-presence record, not a directory company.
