Linear Air Pitch Deck: 29-Slide Series B Deck

Linear Air positions itself as a digital marketplace for the air taxi industry, aiming to solve the inefficiencies of regional travel. By connecting passengers directly with operators of small aircraft like the Cirrus, they seek to offer a 'pleasant' alternative to 'painful' commercial airlines. The deck highlights a transition from manual booking to a mobile-first app ecosystem for both customers and operators. Notably, the presentation includes a highly specific Series B terms slide, citing a $4.66 million pre-money valuation and a maximum offering of $3.5 million. While the team boasts sig…

Frequently asked questions

What is Linear Air's core business model?

Linear Air operates as a digital marketplace connecting passengers with air taxi operators. According to slide 16, they avoid aircraft ownership risk, focusing instead on providing a platform for real-time booking, online quotes, and secure payments. They provide value to operators through business analytics and decreased hands-on administrative time, as detailed on slide 13.

Who are the key people behind Linear Air?

The team is led by CEO William Herp, who previously founded e-Dialog. The management includes Peter Schmidt (Senior Technology Advisor), Scott Healy (Senior Marketplace Advisor), and Melissa O'Shea (VP Sales & Ops). The advisory board features high-profile names such as Harvard Professor Clayton Christensen and Spark Capital General Partner Santo Politi, as listed on slide 7.

How does Linear Air differentiate itself from commercial airlines?

Linear Air uses slide 10 to frame commercial airlines as antiquated and time-consuming. They pitch the air taxi experience as a 'point-to-point' service that uses regional airports to optimize travel duration. The visual comparison shows a crowded airline cabin versus a private, two-passenger Cirrus aircraft cabin to emphasize comfort and exclusivity.

What are the specific terms of the funding round mentioned?

Slide 25 outlines a Series B round with a minimum offering of $1.5 million and a maximum of $3.5 million. The pre-money valuation is set at $4.66 million, with a price per unit of $1.30. The security type offered is Preferred Equity, and the minimum investment size is $25,000.

What technology is Linear Air developing?

The company is focused on a mobile feature rollout for both sides of its marketplace. Slide 4 illustrates a Customer App for booking and trip management, and an Operator App for trip acceptance and passenger check-in. The goal is to transition away from manual, email-based processes to a frictionless digital environment.

What the Linear Air Taxi pitch deck was used for

This deck is a 29‑slide Series B investor presentation for Linear Air Taxi, an air‑taxi and private charter marketplace digitizing regional air travel by connecting passengers with small aircraft operators. The presentation was distributed via OfferBoard Securities and is explicitly structured as a private placement for accredited investors under Regulation D. It appears to date from around September 2015, based on a traction slide titled “September 2015 Update” showing year‑to‑date marketplace billings and customer acquisition metrics. The raise is aimed at scaling Linear Air’s digital marketplace, operator network and mobile apps for operators and passengers in the air taxi segment.

Business model: Operator of an online charter marketplace that connects travelers with air taxis, private jets and other small aircraft via its own site and travel search partners, offering point-to-point regional flights without memberships or quote‑waiting.

$3.1M raised (aggregate, various rounds).

Round: Series B private placement to accredited investors under Regulation D, using OfferBoard Securities as placement agent.

Year: 2015 (inferred from the “September 2015 Update” traction slide within the deck).

Use of funds as presented: Scaling Linear Air’s digital marketplace for air‑taxi and charter flights, including operator and passenger apps, expansion of the operator network into new U.S. regions, and continued optimization of online travel‑search customer acquisition.

What happened after the Linear Air Taxi deck

After its early years operating very light jets and turboprops from bases in the Northeast, Linear Air evolved into an online air‑taxi marketplace launched in 2013, expanded along the East Coast with distribution through major travel‑search sites, and continues to operate as a privately held charter and air‑taxi provider headquartered in the Boston area.

• Launch of the digital marketplace and booking platform in 2013, connecting hundreds of operators and over 1,700 small ai
• Expansion of air‑taxi service along the U.S. East Coast and integration with online travel search platforms such as Kaya
• Recognition in industry and business press for navigating supplier disruption and evolving the model toward an online pl

What the Linear Air Taxi deck got right

• Demonstrated marketplace and air‑taxi segment traction with high year‑over‑year growth. The September 2015 update slide reports $2.9M total marketplace billings year‑to‑date and $1.5M air‑taxi segment billings, with YTD billings up 230% year‑over‑year and September up 250% over September 2014, indicating strong GMV growth in the marketplace and core air‑taxi segment at the time of the Series B.
• Attention to unit economics and CAC in the air‑taxi segment. The deck provides granular air‑taxi segment customer acquisition metrics, including a search CAC of $601 and an overall CAC of $312, alongside a target 12‑month customer margin value of $1,000, showing that the team closely tracks acquisition economics and is designing toward positive LTV:CAC.
• Strong advisory bench and investor affiliation. Linear Air’s team slide features notable advisors and investors such as Clayton Christensen (Harvard Business School professor and author of “The Innovator’s Dilemma”) and Santo Politi (co‑founder and general partner at Spark Capital), augmenting the credibility of the management team and strategic guidance.
• Clear product vision for digitizing operator and passenger workflows. Product slides outlining operator and customer apps emphasize transitioning from email/web‑based trip acceptance and booking processes to mobile apps with check‑in and trip management, illustrating a clear vision for digitizing manual workflows on both sides of the marketplace.
• Compelling dual‑sided value proposition for passengers and operators. The deck’s narrative frames air taxi as filling “a real and growing need” by offering a better passenger experience, tangible operator benefits, and market growth via a digital marketplace, which succinctly articulates value for both demand and supply and positions investors to benefit from market expansion.
• Robust securities disclosure aligned with Regulation D private placement requirements. The important disclosures slide thoroughly explains that the offering is a Regulation D private placement restricted to accredited investors, highlights illiquidity and high risk, and warns that additional capital may be needed, demonstrating a conscientious approach to investor risk communication and regulatory compliance.

What could have been stronger

• Limited visibility into revenue quality and profitability. The September 2015 update slide reports marketplace billings and air‑taxi segment billings but does not tie these to recognized revenue, margins, or unit economics beyond a target 12‑month customer margin value, leaving investors without a clear view of profitability or path to sustainable economics.
• CAC and customer value metrics presented without supporting cohort data. Customer acquisition cost (CAC) for the air‑taxi search segment is shown as $601, and overall CAC $312, but the deck only presents a target 12‑month customer margin value of $1,000 without demonstrating cohort retention, repeat usage, or realized margin, which may make the claimed margin value feel aspirational rather than evidenced.
• Operator network strength not quantified. The deck highlights a marketplace connecting passengers with small aircraft operators and mentions operator acquisition plans, but the available slides do not show quantitative data on operator supply (number of operators, aircraft, geographic coverage, capacity) or operator retention, which weakens the marketplace “network” story.
• Business‑specific risks underdeveloped compared to securities risk disclosures. While the disclosures slide clearly outlines private‑placement risks and illiquidity, the available text does not show a slide explicitly detailing key business risks (regulatory, safety, dependence on partners like Kayak, macro sensitivity), which would help investors assess risk beyond generic securities warnings.
• Competitive landscape and differentiation only lightly addressed. Competitive positioning is alluded to in the narrative that air taxi fills a real and growing need and that the digital marketplace will grow the market, but the accessible slides do not show a structured competitive landscape, pricing comparison, or differentiation versus other charter platforms, limiting investor ability to benchmark Linear Air.

How an investor would read this deck

What draws attention

• Marketplace billings growth and air‑taxi segment traction, including the reported 230% YTD and 250% September year‑over‑year increases.
• Customer acquisition cost and target margin metrics in the air‑taxi segment, which directly inform LTV:CAC and scalability assumptions.
• Strength and credibility of the team and advisors, particularly the presence of Clayton Christensen and Santo Politi, which may validate the vision and prior backing.
• Regulatory and structural setup of the offering, including reliance on a private placement agent and restrictions to accredited investors under Regulation D.
• Dependence on and performance of distribution channels such as Kayak and other internet travel search partners, which are referenced as drivers of customer acquisition.

Risks that stand out

• Private placements are illiquid and high‑risk, as explicitly stated in the disclosures slide, with investors urged to be able to lose their entire investment and warned that the issuer may require additional capital with no guarantee of securing it.
• The model depends on a distributed network of Part 135 operators and on travel‑search partners such as Kayak and Hipmunk for customer acquisition; changes in partner policies, search economics, or operator economics could materially impact growth.
• High reported CAC figures for search customers in the air‑taxi segment combined with an aspirational target margin value could imply sensitivity of profitability to marketing efficiency and customer retention.
• Regulatory, safety, and operational risks inherent in air‑taxi and charter services—such as FAA oversight, operator compliance, and liability in incidents—are structural to the sector even if not detailed in the deck.
• Marketplace growth and geographic expansion plans increase complexity in managing operator quality, customer experience, and pricing across thousands of regional airports, potentially stretching operational capabilities.

Questions this deck invites

• How do reported marketplace billings and air‑taxi billings in 2015 translate into recognized revenue, gross margin, and contribution margin, and how have these evolved since the deck was created?
• What empirical data supports the target 12‑month customer margin value of $1,000 (repeat bookings, cohort retention, segment profitability), and how do LTV and CAC compare across acquisition channels like Kayak vs word of mouth?
• What is the current size and composition of the operator network (number of operators, aircraft, geographies), and what are the key contractual and regulatory constraints governing these relationships?
• What capital has been raised to date beyond the $3.1M aggregate funding reported by PitchBook, and what portion was specifically tied to the marketplace expansion initiated in 2013 and described in the Series B deck?
• How has Linear Air’s business model and product evolved since 2015, particularly in response to supplier changes, competitive platforms, and macro events affecting regional air travel, and what are the main business risks today compared to

What founders can take from the Linear Air Taxi deck

• Including a detailed securities disclosure slide tailored to a Regulation D private placement clarifies risk, investor eligibility, and illiquidity up front, which can build trust with sophisticated investors when raising a Series B via a placement agent.
• Presenting concrete, time‑stamped traction data—such as year‑to‑date marketplace billings, segment billings, and year‑over‑year growth percentages—helps investors quickly gauge momentum, especially in marketplace businesses where GMV growth is a key signal.
• Explicit CAC numbers for specific channels (search customers vs overall) and a target customer margin value show that the team is tracking acquisition economics, but investors will expect supporting retention and margin data to validate those targets.
• Featuring credible advisors and investors, such as Clayton Christensen and Santo Politi, with clear titles and affiliations, strengthens perceived strategic guidance and prior validation, provided their roles and engagement are well‑explained.
• Clearly separating operator and customer app experiences in the product vision (transitioning email/web processes to mobile trip acceptance, booking, and check‑in) illustrates how technology can simultaneously improve both sides of a marketplace.
• Articulating how the current manual booking process for air taxi is inconvenient and inefficient for both passengers and operators sets up a strong problem statement that makes the case for digitization and a marketplace solution more compelling.
