Quick Answer: spARK Labs by ARK Invest is St. Petersburg’s primary tech incubator, a nonprofit operating inside the ARK Innovation Center at 1101 4th Street South in the Innovation District. Formerly the Tampa Bay Innovation Center, it rebranded in November 2025 under CEO Becca Brown and filled all 45 private office suites by March 2026, with a waitlist. Founders can still join through co-working and dedicated-desk memberships, structured on 12-month terms, and access lab space, mentorship and ARK Invest’s research network. The organization is also launching an early-stage venture fund and angel network to close the region’s seed-capital gap.
Key Takeaways
- spARK Labs focuses on ARK Invest’s five research themes: artificial intelligence, robotics, energy storage, digital assets/blockchain and multiomics biology.
- Private offices are full; co-working and dedicated desks remain open, and memberships run on 12-month terms.
- Moffitt Cancer Center is colocating researchers at spARK Labs and launching Speros by Moffitt in St. Pete, putting oncology AI inside the incubator.
- An early-stage venture fund and angel network, announced in mid-2026, is the first dedicated seed vehicle tied to the incubator.
- The building is the ARK Innovation Center; the incubator is spARK Labs. The two names are used interchangeably locally but refer to different things.
What Is spARK Labs?
The organization traces to 2003 as the Tampa Bay Innovation Center, a state-supported incubator that moved from downtown offices into the purpose-built ARK Innovation Center after Cathie Wood relocated ARK Invest from New York to St. Petersburg in 2021 and agreed to back it. Becca Brown became CEO and president in July 2025, launched a new incubator program in October and rebranded the nonprofit as spARK Labs by ARK Invest in November. At the end of 2025 the center was about 60 percent full; by March 2026 all 45 offices were taken.
Brown describes the model as sustained incubation for deep-tech founders rather than a cohort-based accelerator: members stay for a year or more, use hands-on build space and hardware labs, and plug into ARK’s analysts and venture network. She has said she dislikes Silicon Valley comparisons and points instead to Tampa Bay’s business climate, quality of life and defense-technology ties through MacDill Air Force Base.
How Do You Join spARK Labs?
- Confirm fit. spARK Labs prioritizes companies aligned with ARK’s themes. A restaurant app or services business is better served elsewhere; a robotics, AI, energy-storage or biotech startup with a working prototype is the target profile.
- Choose a membership tier. Private office (currently waitlisted), dedicated desk, or co-working. All are 12-month commitments.
- Apply through sp-ark-labs.com. The application asks for company stage, team, technology and what you need from the community.
- Interview and onboarding. Accepted members are placed into programming: workshops, founder office hours, investor introductions and the ARK Big Ideas Summit hosted at the center.
- Graduate or grow. Brown expects some companies to outgrow the space while others extend, which is how office availability will open up.
How spARK Labs Compares to Regional Options
| Incubator | Location | Focus | Model | Best For |
|---|---|---|---|---|
| spARK Labs by ARK Invest | St. Pete Innovation District | AI, robotics, energy storage, blockchain, multiomics | 12-month membership, office/desk/co-working, ARK network | Deep-tech founders with a prototype |
| Tampa Bay Wave | Downtown Tampa | Software, fintech, healthtech, cybersecurity | Cohort accelerators (90 days), diversity-focused tracks | Scalable software startups seeking structured programs |
| Embarc Collective | Water Street, Tampa | Broad tech | Membership hub with coaching, no equity | Early software companies wanting coaching and community |
| St. Pete Greenhouse | 440 2nd Ave N | Main Street small business | Free counseling, licensing help, city grant programs | Non-tech and local service businesses |
| Maritime and Defense Technology Hub | Port of St. Petersburg | Marine tech, defense, autonomous systems | Leased office and shared space | Ocean-tech and defense contractors |
Founders in the blue economy should look first at the Maritime and Defense Technology Hub, which is two blocks from spARK Labs and serves the same district with a different tenant profile.
Where Does the Money Come From?
Access to capital remains the biggest complaint among early-stage Tampa Bay founders, and it is the gap spARK Labs is now trying to fill directly. ARK Invest has run its later-stage ARK Venture Fund for several years; the new early-stage fund and angel network, announced in June 2026, aims to educate new angel investors, expand the local investor pool and write first checks into companies across ARK’s themes. Brown has said the fund may also support other regional organizations. Separately, Moffitt’s Speros initiative brings a research and commercialization partner with its own funding channels into the building.
What This Means for St. Pete Businesses
For founders: the office waitlist is real, but the desk and co-working tiers are the practical door in. Programming, investor access and the Moffitt collaboration do not require a private suite.
For investors: the angel network is the first organized way for local accredited investors to see deal flow curated by ARK’s research team. Expect it to become the default seed source for St. Pete deep tech.
For service providers: 45 resident startups plus co-working members represent a concentrated market for legal, accounting, IP, recruiting and lab-supply vendors. The center hosts regular public events that are the easiest entry point.
For landlords: spARK Labs filling up a year ahead of plan is the clearest demand signal yet for flex and lab space near the Innovation District.
Brian’s Take
The most important thing that happened here is not the rebrand; it’s the capital stack. Incubators without a fund are networking clubs. ARK putting an early-stage vehicle and an angel network behind spARK Labs, plus Moffitt bringing oncology AI into the building, turns a co-working space into an actual pipeline: research theme, prototype, first check, clinical partner. The risk is concentration. Everything routes through one firm’s five investment themes and one founder’s brand, and a bad year for ARK’s public funds would be felt on 4th Street South. For now, though, St. Pete has the only incubator in Florida where a founder can sit across the table from the analysts who decide what disruptive innovation means. Founders who fit the thesis should apply for a desk this quarter, not wait for an office.
