Suffolk Technologies, the venture arm attached to the Boston general contractor Suffolk, announced on 14 September the seven startups selected for BOOST 7, the seventh run of its accelerator for early-stage companies in the built environment. The program starts on 28 September, and its terms — which the release does not mention but Suffolk Technologies publishes on the BOOST page — are $150,000 on a post-money SAFE for 4.5% of the company.
That works out, by our arithmetic, to an implied post-money valuation of roughly $3.3 million. It is a conventional accelerator structure, and Suffolk publishes it rather than leaving founders to ask.
The seven are Airwave, Bear, Forma Systems, Memo, Scale Immersive, Tessi and Tubender. The release’s own headline names what makes this list worth reading: “Bringing Digital Intelligence and Advanced Hardware to the Physical World.”
Two of Seven Make Hardware
The composition is the story. Taking the release’s descriptions as given:
- Tubender is “a portable, automatic conduit-bending machine for commercial electricians that bends EMT and rigid conduit from ½-inch to 2-inch trade sizes.” That is a physical tool; its own site calls it a portable CNC tube bender.
- Airwave makes “smart safety glasses for physical work that offer hands-free video and photos, voice Q&A, and automated inspection and safety documentation.” Wearable hardware with a software layer on top.
- Memo is “a voice interface for construction teams that connects to existing jobsite radios,” turning field speech into “actions, alerts, and project updates.” Software, but software whose input device is the two-way radio already clipped to a foreman’s belt.
- Bear is “a code-first AI construction and BIM modeling platform that turns project data into executable models for visualization, takeoffs, engineering, and procurement.” Its site is a holding page.
- Forma Systems is “a structural optimization platform that automates preliminary engineering to create code-compliant, fabrication-ready designs that reduce material use and cost, starting with precast concrete.” It is unrelated to Autodesk’s Forma, despite the name.
- Scale Immersive is “a visualization platform that allows real estate, architecture, and construction teams to click, tap, or walk through a building before it’s built.”
- Tessi is “an AI-native disaster recovery platform that guides homeowners through assessments, recovery plans, funding, vetted provider matching, and restoration.”
Analysis: the cluster worth noticing is not hardware-versus-software but the three companies — Tubender, Airwave, Memo — whose product meets the worker at a physical object they already handle: a bender, a pair of glasses, a radio. That is a different distribution theory from selling a dashboard to a VDC manager. It is also a harder thing to build and to fund than a web application, which may be part of why an accelerator with a general contractor and a jobsite behind it is where it turns up. That is our inference about the selection, not a claim Suffolk makes.
The seventh, Tessi, is not really a construction company at all — it is disaster recovery aimed at homeowners, which puts it closer to the restoration-claims software this newsroom covered in Rebuild’s $13m round than to anything on a jobsite. Suffolk’s stated remit covers “real estate and development, architecture, engineering and construction, property management, infrastructure, and smart cities,” so it sits inside the mandate; it is simply the widest point of it.
Analysis: The Mentor Bench Is the Harder Thing to Copy
BOOST’s pitch is not the $150,000. It is access: the release describes an eight-week program combining founder programming with “direct engagement with Suffolk Technologies’ growing network of more than 60 Operating Partners, access to Suffolk expertise, and opportunities to explore pilots and customer relationships.”
The BOOST page does not name that network. What it does publish, under a heading reading “BOOST Team and Mentors,” is a roster of individuals with their employers — and that list is worth looking at, because it contains people from companies that compete directly with one another. Procore Technologies, Autodesk, Oracle, OpenSpace, EquipmentShare, Holcim, Kojo, Pype, Ediphi and Rugged Robotics all appear, alongside developers and contractors including Bosa Properties, RXR, Axiom Builders, Tidhar Group and Suffolk’s own staff. To be precise about what is being cited: these are the page’s mentors, not a published list of the “more than 60 Operating Partners,” which is a separate figure the documents do not itemise.
A mentor bench drawn from vendors that compete with each other is, on our reading, the part of BOOST that would be hardest for a rival programme to assemble — capital is available to anyone, and that room is not. Suffolk Technologies is a venture platform led, per the release, by managing partners Wan Li Zhu, Jit Kee Chin and Puneet Mahajan; the convening power plausibly comes from the contractor behind it rather than from the fund, though neither document says so and we are inferring it.
The program also gains a first Executive Director in Jennifer Davis, who the release says “brings five years of experience leading Techstars Boston.” Her quoted remarks open by welcoming the cohort and then turn to adoption rather than returns: “Together with our Operating Partner network, we’re thrilled to work alongside these exceptional founders to help bring their emerging technologies to real-world adoption and accelerate progress toward a more efficient, resilient, and sustainable future.”
The Track Record, As Suffolk States It
The figures below are Suffolk Technologies’ own, reported as the company reports them. Since BOOST launched in 2020, the release says, it “has supported 38 companies.” Alumni “have raised more than $730 million, with 85% raising within 18 months after completion of the program, and have launched more than 80 pilots with industry partners.” Suffolk also says BOOST 7 “saw a nearly 50% year-over-year increase in applications, creating the largest and most competitive applicant pool in the program’s history.”
We have not independently verified the alumni funding total or the 85% figure, and we are not presenting them as verified — they are the program’s account of itself, which is the normal form for accelerator disclosures and should be read with that in mind.
Mechanics, and What the Documents Do Not Cover
The program runs eight weeks from 28 September. Per the BOOST page, it “primarily runs virtually with two in-person events”: a Pre-Launch Program held in Boston on 8–10 September, which has already taken place, and Demo Day on 18 November at Suffolk’s Boston headquarters during the third annual Boston Built Week.
Neither the release nor the BOOST page states prior funding, founder names or headcount for any of the seven companies, and we did not find those details in the coverage we checked. We have therefore described each company as Suffolk describes it. The links above are the URLs Suffolk itself publishes behind each company’s logo on the BOOST page, not domains we guessed from the names — a distinction that matters here, because several of these names are generic enough that guessing would be a wrong link waiting to happen. We fetched all seven and confirmed each resolves to the company Suffolk describes.
Suffolk Technologies invests outside BOOST as well; this newsroom covered its undisclosed equity investment, alongside DPR, in the construction hiring platform Skillit. Suffolk has been publishing research too — we covered its joint white paper with MIT on where AI can take cost and schedule out of a project earlier this month.
What the cohort list tells you, in the end, is where a large general contractor thinks the buildable problems are right now. On this evidence, three of them are within arm’s reach of a person holding a tool.
